Ways to protect your privacy online:
Paul Bischoff's "75+ free tools to protect your privacy online"
Fried's "The Ultimate Guide to Online Privacy"
Privacy Alert's "Internet and software privacy"
Privacy Alert's "Data broker opt-out"
Smartphones: Android, iPhone, etc
- Don't put really private stuff online. At all.
Naked pictures of yourself or your spouse ? Personal embarrassments ? Dark secrets ? Something illegal ?
Just don't put it online, or transmit it over the internet. Maybe don't
even put it on your computer or phone or camera.
- Give "them" as little data as possible.
Don't fill in all of those "profile" fields. Why tell Facebook where you've worked, where you went to school,
who your family members are ?
- Give them fake data.
Don't give them your real birthday, or real mailing address, or real phone number.
[But: if Facebook or whoever later challenges you to produce real ID to verify your account,
and your info doesn't match, you'll lose the account.]
You can get a disposable email address, which exists just long enough to finish registering somewhere:
10 Minute Mail,
A service which will "screen" your real email address, phone number, credit card number by
giving out different info which relays to your info:
(Stop giving out your real personal info online with MaskMe, a new privacy tool).
Maybe in the future we'll get "decoy" tools or services: something that posts fake info online to make it harder for others
to figure out your true info. Fake pictures of you, fake address, fake postings, etc.
- Maybe use login/password info from elsewhere,
instead of using your own.
- Use "blockers".
Several ways to do this:
- Extensions / plug-ins / add-ons in your browser.
(and then go to stop tracking
and stop social-media tracking)
Do Not Track Plus
Wallflower (similar to FacebookBlocker ?)
Disconnect (prevents tracking by Facebook, Google, Twitter)
Priv3 (affects Facebook, Google +1, Twitter, LinkedIn)
EasyPrivacy addition to Adblock Plus
Add-on to control or delete "referer" information in HTTP requests; in browser, do a "Get Add-ons" and search for "referer"
Fighting the System's "Hardening Firefox to Protect Privacy"
Decentraleyes (loads JS libraries locally; Firefox only)
More complex tools:
- Hosts file modifications.
Advantage: affects all browsers and all applications, from one place.
(get from here ?)
MVPS Hosts file
- In your network router.
Advantage: affects all devices and all browsers and all applications, from one place.
- For Android smartphone:
Non-rooted: AdGuard, Netguard, Dns66, AdClear, Block This, Cygery AdSkip.
Rooted: AdAway, MinMinGuard Xposed.
- General OS controls.
Spybot Anti-Beacon (prevents Windows sending info to Microsoft)
- Set the "do not track" option in your browser to (maybe) stop "ad tracking".
In FireFox 10, it's: Options - Options - Privacy - Tell websites I do not want to be tracked.
Jon Brodkin's "Yahoo is the latest company ignoring Web users' requests for privacy"
- Apparently, "opting out" via NAI
stops targeted ads, but does not stop companies from tracking your activities.
- Delete most cookies every now and then.
- Don't always use the same IP address or network, or hide your IP via a proxy or VPN.
And some people say you shouldn't use Google's DNS.
If you're doing illegal things, don't expect a VPN or proxy company and their ISP to shield you if they're served with a court order.
They may be forced to log your activity and trace you and
give the data to law enforcement.
Alan Henry's "Why You Should Start Using a VPN (and How to Choose the Best One for Your Needs)"
Max Eddy and Fahmida Y. Rashid's "The Best VPN Services for 2016"
Hide My Ass! (free proxy server)
can change your MAC address.
- Stay logged out of Google and Facebook et al as much as possible, as you browse other sites.
- Don't use everything from one company.
If you use Google Apps, Google Docs, Google Sites, Chrome browser, GMail, Google search, Google Maps,
and Google+, then of course Google is going to know a lot about you.
Instead, spread it around: Yahoo Mail, Facebook, some free web hosting service, Firefox browser, Google search, etc.
- You can delete your accounts on various services, although often they make it hard
to find out how to do that.
Some people say: instead of just deleting an account, first go in and delete as much of your data as you can, and change
as much of the rest as you can to fake data. Maybe let it sit in that state for a couple of weeks. Then delete your account.
Dibya Chakravorty's "How to clean your digital identity"
- Use the privacy controls in the social networks and sites you use.
Facebook lets you control the access that Apps and external sites get to your data: go to
Account - Privacy Settings - Apps and Websites - Edit your settings.
Melanie Pinola's "The 'Nuclear' Option for Total Facebook App Privacy"
Turn off your Google search history: here
YouTube: profile - Video Manager - History - Clear All Viewing History, and then History - Pause Viewing History,
and then Search History and do the same clear-and-pause.
See and turn off data aggregating by BlueKai: here
Handy central place to start: MyPermissions
- Put tape over the webcam on your laptop.
Kioskea's "Windows 8.1 - Prevent apps from using your webcam or microphone?"
- Turn off the microphone on your laptop or smartphone.
Maybe put a dummy plug into the external microphone jack.
Or put tape over the built-in microphone opening.
Alan Henry's "How to Stop Web Sites from Potentially Listening to Your Microphone" (Chrome only)
Jignesh Padhiyar's "How to Find and Prevent Apps from Accessing Your iPhone's Microphone in iOS 7"
Kioskea's "Windows 8.1 - Prevent apps from using your webcam or microphone?"
- Deleting browser history really does nothing for your privacy, unless someone steals your computer and looks at your history.
- Anything you store on a server may reduce your privacy. Your contact list in email, buddy list on
instant messaging, Friends list on Facebook, etc. Any emails in your Inbox, or saved long-term in a "folder" within
your email service. Okay, email or IM or Facebook won't function without those contact lists. But maybe you shouldn't
use your email as a data store.
- You have few rights to anything you store on or do with company computers or networks.
Don't use them for private things.
Kashmir Hill's "How To Tell If Your Boss Is Spying On You"
- Maybe turn off location-monitoring services and apps in your smart-phone and browser. But your cell-phone company
will always know where your phone is, if it's turned on, or maybe even if it just has a battery in it.
- There are more-aggressive things you can do, but I think the cost/inconvenience is too high for the benefit, in most cases.
(And some of them require your friends to use the same applications, or adapt to your behavior.)
Tor browser, run Linux (because you don't trust Microsoft or Apple),
multiple throwaway email accounts, proxy servers, encryption everywhere, prepaid throwaway phones, email and VoIP services
and social networks specifically designed to be more private, run your own email server, etc.
Peter Bright and Dan Goodin's "Encrypted e-mail: How much annoyance will you tolerate to keep the NSA away?"
Jody Ribton's "The Hostile Email Landscape"
- Your friends and relatives are a threat to your privacy. They may post about you on social networks,
put pictures of you online, mention you in emails.
- There is no such thing as total privacy, or perfect security. If the government or a spy agency or law enforcement
really wants to get your data, they can get it.
- Many apps harvest data from your Contacts list. Maybe keep only essential contacts in there, not everybody.
And for those contacts, keep only essential data (name and phone number) in there.
- Some apps demand a huge list of permissions, to everything in your phone. Maybe don't install those apps;
access the services through a browser instead. For example,
use m.facebook.com or mbasic.facebook.com through a browser instead of the Facebook app.
- Permission-controlling add-on: XPrivacy
- Privacy blocker for your Android smart-phone, to control what info other apps can see:
- There are claims that some apps may listen to you through the phone's microphone, even
when you're not using the app.
- Similarly, I would keep the phone's camera pointed at something uninteresting
when you're not using the phone.
- Older versions of Android give less control over app permissions. So upgrade the version (which may
require getting a new phone, or rooting your phone).
Facebook is a special case, because they know so much about you, and they have code on many
other web sites, and they buy data about you from other services.
Vicki Boykis' "What should you think about when using Facebook?"
- On phones, the Facebook app requires a huge set of permissions, and certainly harvests your Contacts list.
Use m.facebook.com or mbasic.facebook.com through a browser instead of installing the Facebook app.
- Don't fill in all of those "profile" fields. Why tell Facebook where you've worked, where you went to school,
who your family members are ?
- In the browser, use blockers such as:
Wallflower (similar to FacebookBlocker ?)
How do companies justify selling your information ?
- They are giving you a great free service, and they need to make money to keep it going.
- With more info, they can give you more relevant ads and news items and pointers to new Friends.
- They give you lots of ways to control the privacy/selling of your info.
[But sometimes have been caught cheating on this.]
- You agreed to it when you signed up for the service. And you could stop using their service and close your account.
- They sell your info in general/aggregate, not your specific name, address, phone number, etc.
Privacy In General
Why should I care about privacy ? I have nothing to hide.
Suppose you do some searches about cancer, or diabetes, or alcoholism.
Do you want that info popping up the next time you apply for health insurance or car insurance or a job ?
Even if you don't have cancer, diabetes, or an alcohol problem ?
Easiest for the company to just deny you the insurance or the job, rather than investigate or take a risk.
Suppose you're a woman with an abusive ex-husband, or a creepy ex-boyfriend ?
Do you want them to be able to track your location in real-time, or track you
even if you move to another city ? Or to know where your new job is, or who
many of your friends are ?
Suppose some of your friends or family care much more about their privacy than you do about your privacy.
Exposing your info to the world could expose some of their info to the world.
It even could affect future generations of your family: suppose you post about some genetic disease you have,
and years or decades later this affects your descendants ability to get medical insurance ?
Some people do depend on privacy for their profession, or their life. They work in journalism or activism
or investigations. Maybe they live under oppressive regimes, or investigate regimes which have a history
of retaliation against opponents, or work in the justice system (where criminals might retaliate
against them). If the rest of us don't value our privacy, there will be fewer tools
to protect them, too.
From noir_lord on reddit
Some people (including myself) are not comfortable with a faceless corporation knowing
- What medical problems I have (ever googled a medical problem for yourself or someone else?).
- Who my contacts are (if you use their webmail) and what we are discussing.
- Tracking just about every page you visit.
- Build up a remarkably accurate profile of who you are and your life.
- What videos you watch.
- What topics you are interested in.
Now each of those on its own is somewhat unsettling, but when you combine all that together and then
you don't really know how your data is handled now and how it might be handled in the future,
then it starts to get really unsettling.
The thing with all this data is that it just accumulates, and over time the companies can really
build up an accurate profile of you, and that is just f***ing creepy.
From Daniel J. Solove's "Why Privacy Matters Even if You Have 'Nothing to Hide'"
Some responses to the "I've got nothing to hide; you have something to hide only if you're doing something wrong" argument:
- Do you have curtains ? Why ?
- Can I see your credit-card bills for the last year ? Why not ?
- I don't need to justify my position. You need to justify yours. Come back with a warrant.
- I don't have anything to hide. But I don't have anything I feel like showing you, either.
- If you have nothing to hide, then you don't have a life.
- It's not about having anything to hide, it's about things not being anyone else's business.
- You are willing to let me photograph you naked ?
... the nothing-to-hide argument stems from a faulty "premise that privacy is about hiding a wrong."
Surveillance, for example, can inhibit such lawful activities as free speech, free association,
and other First Amendment rights essential for democracy.
Another potential problem ... is one I call exclusion. Exclusion occurs when people are prevented
from having knowledge about how information about them is being used, and when they are barred
from accessing and correcting errors in that data.
Yet another problem ... is distortion. Although personal information can reveal quite a lot about people's
personalities and activities, it often fails to reflect the whole person. It can paint a distorted picture
[and that can have consequences].
What if the government mistakenly determines that based on your pattern of activities, you're likely
to engage in a criminal act? What if it denies you the right to fly? What if the government thinks your
financial transactions look odd - even if you've done nothing wrong - and freezes your accounts?
What if the government doesn't protect your information with adequate security, and an identity thief
obtains it and uses it to defraud you? Even if you have nothing to hide, the government can cause you a lot of harm.
Reasons someone might want to attack you:
Srikrishna Sekhar's "Why worry about privacy?"
Ruth Coustick-Deal's "Responding to 'Nothing to hide, Nothing to fear'"
Patrick Allan's "Why Your Privacy Matters, Even If You're Not 'Doing Anything Wrong'"
New Yorker cartoon
- Your info (personal data, credit card info, etc) can be sold for money.
- Your internet-connected computer can be used as an agent in a bot-net (to send spam or attack other computers).
Another way to look at it: will anyone ever develop a grudge against you,
and look for ammunition against you ? Ways to embarrass you, or harass you ?
Perhaps you'll get involved in a divorce, get in a dispute with a neighbor, get
in a feud with a coworker. Or some idiot on the internet might come after you.
How much information do you want to make available to them ?
From someone on reddit 1/2014:
As an employer I run every name and email address I am given by a potential hire
through Google and Facebook. I look at everything public to make sure there isn't something completely f**king insane.
Things I don't do: I don't hold what their friends say against them. I don't Friend them or try to look at
things that are private. I don't hold it against them if they don't have an account or I can't find it.
I do look at public photos and statuses. I don't care if they go to parties. I do care if they
skip work to do so or because of it.
So far I'd say 80% of the applicants are fine. But in that other 20% I have found obvious racists,
people who actively hate gays, people who play games every working minute (while at work).
Funniest was someone who had set their account to public and constantly complains about being at work
FROM work and asked friends to come by and visit and talk, at a job where that was not appropriate.
For people who apply as interns, I let their school know to have them remind the student to lock down their account.
For people who apply for real jobs, I don't say a word.
Some people say: Innocent people have nothing to fear from government spying.
I'd certainly feel uncomfortable and creeped-out if someone followed me
around all day, videotaping everything I did, documenting every place I went
and everything I did, watching me. Should it be okay for the govt to do this ?
Why was protection from unreasonable search put in the Bill of Rights (4th Amendment) ?
It fits this situation exactly: govt is supposed to have a good reason for invading
Some huge government investigations have targeted and ruined the lives of
innocent people: the McCarthy hearings, the Atlanta Olympics bombing (Richard Jewell was innocent), and the
anthrax attacks (Steven Hatfill was innocent) come to mind.
Government powers have been used to target people with unpopular views, or journalists reporting news
that politicians didn't want reported: FBI under Hoover, Nixon's enemies list.
My response to someone who asked "Why is this NSA scandal such a big deal ? I'm not doing anything illegal.":
1- NSA scandal is just one symptom of a bigger issue: govt checks and balances have broken down.
Intelligence spending and activities are out of control, military spending is out of control,
citizens got panicked by 9/11 and let govt take major new powers and now govt is out of our control.
2- NSA is just one point along a spectrum of threats to you. It is the least likely but most powerful threat.
It points out that you are vulnerable to scammers, stalkers, eavesdroppers, online criminals, etc.
It reveals that our online security and privacy tools and laws are weak.
3- Technology, and the threats from it, will only get more powerful and more invasive in the future.
Insurance companies and advertisers and your wacky neighbor will all get more powerful tools to threaten your privacy.
4- Things you do that aren't illegal still may be private. Why do you have curtains on your windows ?
Why do you close the door when you go to the bathroom ? Would you mind if someone published your tax returns, your salary and net worth numbers,
your credit-card statements, your bank account statements, your medical records ? Why ? You're not doing anything illegal.
Future threats to privacy will be greater:
From Intelensprotient on reddit
... you do not need to be registered with Facebook for them to make a profile for you.
Once you have visited any page that is affiliated with them, they will create a file about
you and collect each and every visit to every site that has a "Like" button or a Facebook plugin.
The amount of data collected this way can be tremendous, which few people realize. Google is even more
extreme, as they collect data from every place that has AdSense, Analytics and similar services,
which basically covers almost everything the average person visits. Those services may not always be
as obvious as a "Like" button - for instance, some are implemented by displaying a single transparent pixel image.
You cannot know what kind of surveillance methods and laws will be implemented in the future.
Already, biometric information gathering such as the identification of people from video recordings
is becoming more and more successful, even prompting for the EU to begin implementing a system
that can link people in public places to their Facebook pages and other photographs. Similar plans
are implemented by the US. Other technologies include public voice surveillance, supervision of vehicle movement
or behavioral analysis in public spaces. All this data can and will be linked and combined with what is collected about you online.
More about the future: new technologies such as Google Glass and face-recognition and license-plate-recognition and CCTV
will connect your "real" life and your online life more tightly, and in real-time. Facebook, law enforcement, even
big retail stores are starting to do facial recognition. Things you do in public without giving your name, or giving fake data,
and using cash, may still be connected back to your personal info.
What you do online won't stay only online; what you do offline won't stay only offline.
Michelle Starr's "Facial recognition app matches strangers to online profiles"
George Dvorsky's "How Your Body's Unique Biosignatures Are Used for Surveillance"
In the future, CCTV and consumer cameras only will get better and better. In public, or through your window,
cameras may be able to read the screen on your phone, hear your conversation from a distance, photograph you in infrared at night.
One of the first users of this is the police force that brought us "stop and frisk":
Joe Coscarelli's "The NYPD's Domain Awareness System Is Watching You"
And "The Internet Of Things" is coming: your own devices (car, house, refrigerator, toilet, etc) will make more and more data available,
and some of that could be used to reveal your activities.
Another hint about where tech may go in the future: scanning your face and posture and movements to diagnose
Ben Amirault's "Diagnosing depression with facial recognition technology"
Maybe a good thing in a doctor's office. Maybe a bad thing when a retailer is doing it
and selling the data to insurance companies.

Neil J. Rubenking's "5 Ways Identity Theft Can Ruin Your Life"
- Many things people post about may be technically illegal. They may be rarely caught or prosecuted.
But bragging about them online creates a permanent record, and who knows what authority might
see them someday and decide to act ? Posting about downloading movies or music for free, about
how drunk you were when you drove home last night, about how you got back at your Ex by doing some nasty prank.
- Someone researching you in the future may not like what they find.
A potential employer, a potential mate, an insurance company.
How will they react when they see you complaining bitterly about your current boss,
bragging about how many one-night stands you have, how much you drank or smoked last weekend ?
And they may not distinguish between 18-year-old you and 28-year-old you.
- People who have sensitive jobs, or may ever find themselves in sensitive jobs, have to
be especially careful. Teacher, politician, priest, banker, reporter, law enforcement,
any bonded job (bank guard, cashier, treasurer, etc). Teachers have been fired for online pictures of
them doing things that are deemed bad examples to students.
- All of the online world carries risks; it's not just a problem with social networks such as Facebook.
If you comment on YouTube or newspaper sites or blogs, you might be identifiable.
Using pseudonyms can help avoid this, but may not avoid it completely.
- Risks come from your friends and their behavior, too.
If a friend or someone else at the same party posts a party-video or party-pictures,
and you're tagged on it, or identifiable in it, you may have a problem.
Suppose one of your friends Photoshops your face onto a picture of someone doing
something obscene, and the resulting image gets out into public ?
- Some posts can violate rules at your current job, or even violate SEC regulations. Or just
massively irritate your boss or coworkers.
Some societal nuances to privacy:
- Our goal as a society shouldn't be total privacy for citizens. Should your neighbor be
guaranteed total privacy as he abuses his wife and children, or brews up anthrax or meth in
his garage ?
- Of course the government needs to spy, on foreign citizens and foreign leaders and domestic citizens.
It helps prevent wars and terrorist attacks, and helps defend against espionage from foreign sources.
In some cases, it may defend against crime and commercial espionage.
Sure, often the effectiveness is exaggerated and the costs (in money, and to our privacy) are not examined.
And today in USA we don't have proper controls and transparency.
We need to find the appropriate balance. But the spying has always happened and there are good reasons for it.
A technical issue: it's not clear that NSA can separate "domestic" and "foreign" any more, even if it wanted to.
It is estimated that 90% of all internet traffic passes through US servers. US companies have servers all over the world.
There are plenty of foreign visitors,
temporary residents, and illegal aliens or illegal immigrants inside the USA at all times. Many
US citizens routinely reside or travel overseas. US citizens or residents
have traveled to foreign countries to join terrorist groups or be trained by them. US citizens or residents
have sent money or information to foreign terrorists. US citizens have committed
terrorist acts inside USA, motivated by foreign or domestic agendas.
Some say that the costs of the spying outweigh the costs of terrorism.
I agree that the costs of spying (our privacy, our rights, money, reputation)
are large. But the cost of terrorism shouldn't be judged solely by past events, bad as they were.
The future of top-level terrorism is in bio-technology. A major bio-attack could kill hundreds of millions of people.
I don't know if it will happen, or when it will happen, but you can't judge costs just by the past.
Better arguments: spying usually doesn't stop terrorism, other risks (homicide, drunk driving, disease) are greater,
perhaps we should address the causes of terrorism.
Spirit of the law
The Onion's "President Curbing NSA Spying"
- Even if we develop tools to give each person total control over their private data,
this may not result in "total privacy". Each individual may find it in their self-interest
to give away some of that data to Facebook, Google, and other companies in exchange for
services. And in fact that is what happens today in many cases: we voluntarily give
away some measure of our data, to get benefits. But there are other cases where our data is taken against our will,
or without our knowledge. Better tools and laws can address that issue.
- There is societal pressure to reduce your privacy.
If all of your family and friends are on Facebook, they will ask "Why aren't you on Facebook too ?"
They will make announcements or post pictures only on Facebook, and if you aren't on there, you will miss out.
If you refuse to provide certain info that everyone else provides, insurance companies
or others may refuse to deal with you.
If you refuse to answer police questions that most people answer routinely,
you may find yourself given extra scrutiny.
My response to an article saying "Google and Facebook and Twitter have not created new products that stand alone
like a car or a new house; they have created things that invade every other aspect of the economy and our culture.
That is a different level of power.":
I think this is overblown. I could stop using Facebook and Google and Twitter tomorrow,
with some effects but not big effects on my life. I can give them false info, give them minimal info,
use alternatives to them, do without them.
Government and military and police have the potential to have unavoidable, huge effects on my life.
They take some of my money (and give me services) without much choice on my part. Sometimes they cause other people to attack our country.
They have access to my tax information, credit info, bank account info, phone records, etc.
Some companies have large physical effects on my life and my health. Fossil-fuel power companies,
and other companies that put who-knows-what into the air I breathe and the food and drink I consume.
Other companies have pervasive effects throughout our economy and/or culture. TV networks. Phone companies. Walmart. Exxon.
The two political parties control much of what happens in the government and culture and economy.
Super-rich people could destroy me with lawsuits, or buy laws that affect me severely.
No, I think Facebook and Google and Twitter are pretty low on the list of powerful entities to worry about.
Companies that could have large access to your activities:
- Your OS vendor (especially if they do "telemetry", or server-based voice command processing).
- Your anti-virus vendor.
- Your browser vendor.
- Your browser add-on vendors.
- Your search engine vendor (especially if they do "search suggestions").
- Advertising networks/brokers (if you don't run an ad-blocker).
- Other vendors who have code/data on many different web sites, such as Facebook "Like" button, or Flash add-on (if you don't run blockers).
- Your router vendor.
- Your ISP (Internet Service Provider).
- Your DNS (Domain Name Service) provider.
- Your email provider.
- Your phone service provider.
- Your phone OS provider.
- On older versions of Android, vendor for any of your installed phone apps.
Some ways technology is stretching old notions of privacy:
Technology makes possible:
- Constant, multimedia surveillance of people.
- Connecting together various flows of information about a person.
- Publishing that information globally.
- Storing that information publicly forever.

Evan Dashevsky's "Admit It, You Don't Care About Digital Privacy"
The law (in USA):
[Mostly from Daniel Zwerdling's "Your Digital Trail: Does The Fourth Amendment Protect Us?"
Two legal ways the govt or others can get your data:
- Warrant: requires "probable cause"; has to be signed by a judge.
- Subpoena: requires "relevant to an investigation"; can be signed by a prosecutor, some other
govt agents, in some states even by a lawyer (such as in divorce case).
Fourth amendment of the Constitution protects against search and seizure.
But location of your data matters:
- In your home: requires a warrant.
- If it's shared with someone else (web company, phone company, your bank, your credit-card company,
etc): either subpoena or warrant. There may be even lower standards if the data has been on there more
than 6 months, so is considered "abandoned" by the law (1986 Electronic Communications Privacy Act).
But there are other standards. For example, once NSA collects masses of phone-metadata, it isn't supposed to search within it
and use pieces of it without a "reasonable, articulable suspicion" (RAS) that it is related to terrorism.
[from Ryan Lizza's "State of Deception"
And your cell-phone data may get swept up with that of criminals, with each phone company applying its
own rules about what data is given to police.
[from David Kravets's "Cops and Feds Routinely 'Dump' Cell Towers to Track Everyone Nearby"

- Password security:
Use the password and security features of your device and software;
many people don't even bother to set a password !
Use a password manager:
Password manager makes it easy to use a different password
for every web site, can generate hard-to-guess passwords, can remind
you to change passwords periodically.
Some passwords they don't
help manage: your PC's BIOS and Windows passwords,
encrypted disk drive's password, physical-world passwords such as ATM PIN.
Features to consider:
Wikipedia's "Password manager"
- Online: your passwords are stored online, which is bad (have to trust that place;
what if they go bankrupt)
and good (accessible from any device; backed up). Usually there will be a synchronized local
copy of your password database, too.
- Local application: your passwords are stored only on your device.
- Feature of a security suite: same as local application.
- Browser feature: first implementations of this had some holes/bugs, no way to
sync across different brands of browsers, maybe no way to sync across multiple devices.
- Devices supported (PC, smartphone, tablet, etc).
- OS's supported.
- Browsers supported (almost all managers use a related add-on in your browser).
- Syncing devices to each other.
- Cloud backup.
- Handles credit card info.
- Handles application passwords.
- Supports two-factor authentication.
- Supports fingerprint (biometric).
- Miscellanous: form-filling, import from other managers, automatic login capture, profile info, notes, credit report monitoring, etc.
Some free password managers:
(more than just a password manager)
seems to have every possible feature (some require premium version), and support every possible environment,
and gets top ratings, so I chose it.
Passwords, from article by Jacob Bernstein in The New York Times, June 24 2012:
... it is less clear to cybersecurity experts that having a password with extra numbers
or special characters actually makes customers safer.
"People's choice of passwords is not the real problem today", said Dr. Joseph Bonneau,
a University of Cambridge researcher who studies cyber security. "The real problem
is typing in passwords to the wrong Web site, which is stealing them."
So why are Web sites suddenly requiring users to add special characters or numbers ?
"It's security theater", Dr. Bonneau said. "So people feel safe.
It makes the Web sites seem like they're taking things more seriously, when in fact most of them
have no control if you have malware. In absence of a way to tackle bigger problems, it's easy to add restrictions.
They don't want to seem less secure than competitors."
Some sites offer two-factor authentication, where you can't log in unless you possess both knowledge (password) and
your registered device (phone or dongle or token). When logging in to the site,
you have to type in your usual password, plus some one-time passcode
you get through the device.
For standard web sites, usually that requires you to have a phone that does SMS (text messaging);
the site will SMS the passcode to your device, and then you type in the passcode on the web site.
[Note: SMS is expensive in Europe.]
Sometimes phones also can get the passcode via voice call or through a mobile app.
There is at least one application that doesn't require using a phone:
VeriSign "VIP Access Desktop"
Runs on a computer, generates the passcode you need.
But only works on a few sites. Most sites do SMS to a phone.
Some people have tried using an SMS application or site (such as Google Voice), instead of a phone.
Often doesn't work.
However you do it, check ahead of time to see what happens if you lose your device (or it dies, or the battery runs out),
or have to reinstall the security application (which
may change the security ID), or want to log in through some other computer (if using the no-phone option).
I guess you'd have to contact each vendor and answer security questions to get them to
set a new password and security ID on your account. This could be a real pain if you upgrade to a new phone or
laptop; you'd have to contact all of the vendors you use. Some systems have a way to print out verification
codes to use if your device fails; don't skip this step when turning on two-factor security.
Eric Ravenscraft's "What Happens If I Use Two-Factor Authentication and Lose My Phone?"
(Found these instructions for VeriSign VIP Access: "You need to save the VIP.tok from \Application Data\VIPAccess.
You also need to save the registry keys
HKLM\Comm\Security\Crypto\UserKeys\Microsoft Enhanced Cryptographic Provider v1.0\VipAccessKeyContainer
None of the consumer/free solutions seem to work for cases where multiple people would be sharing the same account,
or where you switch around a lot and carry only one of your multiple devices (phone, tablet, laptop) at a time.
If you use a computer (non-phone) app, how would that work with multiple computers (home desktop, work desktop, laptop) ?
As of 9/2013, it seems some major sites that support two-factor authentication are
Google, Facebook ("Login Approvals"), EBay, PayPal, ETrade, Twitter, Dropbox, Wordpress, Yahoo! Mail, (as of 11/2015) Amazon.
Not supported on Citigroup, my credit union (a smallish place), my 401K manager (a large national corp).

- Use fake data as answers to the "security questions".
If you give fake data as your mother's maiden name, town where you were born, etc, no attacker can look that up
somewhere and know what answer to give. Of course, you have to write down those answers yourself.
- Computer security:
Run the newest or newest-but-one version of your operating system, and turn on auto-updating.
- Anti-virus software:
Install it, set it to update automatically, run a full scan every now and then.
Things that loosely fall into this category:
I use AVG (free) and Malwarebytes (free).
If you use Adblock Plus,
you can then install a malware site filter.
Aurelian Neagu's "10 Warning Signs That Your Computer is Malware Infected"
/r/techsupport's "Official Malware Removal Guide"
Set your browser to update automatically; browsers contain security features that should be kept up to date.
Enable security features in your browser: IE's "SmartScreen Filter", Firefox's Options/Security tab,
Chrome's "Enable phishing and malware protection", Opera's "Enable Fraud Prevention".
- Use an "ad-blocker" add-on in your browser to protect against ads
that contain malware (malvertising).
(get from here ?)
- Turn off the computer:
When not using the computer, turn it off, so attacks can't get in.
Maybe put critical data on a thumb-drive or external drive, and only
mount that drive for brief periods when you need to use that data.
- Application-level encryption:
For communication apps, person at other end has to use same software.
Encrypted Communication (Firefox only;
encrypt/decrypt blocks of text in web pages or docs)
SafeGmail (GMail only; Chrome only)
Encipher.it (Chrome add-on, or client app; encrypt/decrypt blocks of text in any web page)
Other solutions require you (and person at other end) to change email providers or use different applications.
Not feasible, in my opinion.
We need transparent encryption of email:
I wish some large email provider, such as GMail or Yahoo Mail, would start using end-to-end (client-to-client) encryption routinely,
and transparently. When you click the Send button, software (maybe an open-source browser plug-in) looks to see
if your recipient has a preferred encryption method and public key registered anywhere (or if
one is cached locally, via prior key-exchange). If recipient does,
the message gets encrypted (by open-source browser plug-in) via that method before sending.
If recipient is not registered anywhere, message goes unencrypted, as usual. Simple !
And now the email provider itself can't read or decrypt the messages, and
can't decrypt them for the government.
The company that does this first could seize the mantle of "privacy champion".
They still could do targeted advertising based on keywords: the plug-in that does
the encryption first extracts a few keywords, and then passes them on along with the
Searching your messages on the server would be affected; the server
wouldn't be able to read the text of the messages. I suppose you could do a search by
sending all of the encrypted messages to the client (browser), and decrypting them and doing the search there,
but that would be horribly inefficient (but possible). Or search-keywords could be sent to the server along with each encrypted message
(compromising security a fair amount, but enabling searching).
Spam-filtering would be affected. If a spammer is willing to look up your public key and encrypt their message to you,
it will have to be caught on the client, not the server. That's an issue. Need an open-source spam-filter plug-in or something.
The reason I want an existing large provider to do this, as opposed to new secure-email startups,
is that the change by an existing large provider would immediately make encryption easily available to hundreds of millions
of existing users. No need for users to change providers, with new UI and new email addresses and having to transfer their contact lists.
Most users will NOT move to new secure-email services; we need to get encryption into existing services.
is a bit like what I want, although it's far from as transparent and integrated as what I outlined (which
requires changes by Google, Yahoo, etc).
Google and Yahoo were working on a couple of end-to-end things, but as of 2/2017 seem to have dropped their efforts.
Once we have end-to-end encrypted message bodies, a few changes could secure the meta-data better.
Move the subject line inside the message body before encrypting, and move it back out when decrypting,
so all of the servers and middlemen see only a dummy subject line.
Encrypt the destination user's email address in some way that the destination server can decrypt,
so only the originating client and the destination server and destination client know the full destination address (all
other servers and middlemen can see the destination server name, but not the real destination user name).
Do same with originating user's email address, in way that only originating server and originating client and destination client can decrypt.
Example: a middleman would see "From: 5$33!8*AW@gmail.com To: 7^h$g#FS@yahoo.com Subject: none".
GitHub's "Overview of projects working on next-generation secure email"
- Monitor your accounts for evidence of problems:
Check the activity in your credit card and bank accounts every week or two.
Check your credit record annually (free), or use a credit-monitoring service.
Maybe use an identity-theft warning service. Maybe freeze your credit (a "credit freeze" or "security freeze";
usually free to apply and $5 to remove) or institute a fraud alert (free, but not as good).
Kristin Wong's "Keep Your Identity Secure With a Credit Freeze or Fraud Alert"
FTC's "Credit Freeze FAQs"
- Be smart:
Be aware of security threats, and don't fall for them. Know how to recognize spam,
scams, phishing attempts. False alerts that say "something is wrong with your computer,
better run this scanning software right away !". Be especially careful when downloading and installing software.

If someone says "I got a strange email from you, your account must be hacked !":
This does not necessarily mean someone has been "hacked".
Perhaps some software scanned Facebook, found that A and B are Friends, and found A's email address
in A's Facebook profile. Then a scammer sends an email to A, claiming to be from B.
One way to check: A's email client may have a "show details" button or link,
where you can see the actual email address the email originated from.
It probably isn't B's email address, even though the displayed "from" name is "B".
And of course scams are not just online, they also can come via phone or snail-mail or in person.

Theft recovery software
All of these products work by your computer sending "here I am" messages over the internet
to a central site. But if the thief breaks up your computer to sell for parts, or uses it
but never connects to the internet, the product won't work.
One note: if someone (a hacker or ex-spouse) finds out your theft-recovery password, they
might be able to tell the software to delete all of your data, even though your
device hasn't been stolen !
Password / login issues:
All of these theft-recovery products work by your computer sending "here I am" messages over the internet
to a central site. But a computer running Windows 7 Home can't access the internet until the user has logged in to Windows.
So the thief has to be able to get past the BIOS/firmware password prompt and the Windows password prompt.
There are three ways this could happen:
1- you always use your laptop with no
passwords set, or
2- you have passwords set, but the thief resets the BIOS password and OS password (it can be done),
and then logs in, or
3- you have passwords set, but the thief resets the BIOS password (it can be done),
reformats the hard disk, installs a new OS, and then logs in.
In case (1) or (2), obviously a thief or casual snoop can log in right away, and read all of your files. Unacceptable.
Under Windows 7 Home Premium, there is no way to have a Guest account that can log in but then
be unable to read files.
In case (3), a few of these theft-recovery products can survive the reformat/re-install and
be capable of reporting their location when the thief eventually logs in and connects to the internet.
Case (2) or (3) represents a sophisticated thief; they could just pull out the hard disk and attach it to
another PC, so they could read your files that way. Unless you're using some special full-disk-encryption product.
And case (2) or (3), the sophisticated thief, probably would be aware of the existence of theft-recovery products.
So it seems to me that this is a Catch-22 situation: these theft-recovery products work best in case (1),
but that's the case where you've left your data most vulnerable to a naive thief or casual snoop.
And in case (2) or (3), nothing protects you very much from a sophisticated thief.
I believe Linux and Mac systems are slightly better than Windows in that: once the OS password prompt is displayed,
the machine can connect to the internet, even though the thief hasn't logged in to the OS.
The thief would still have to get past the BIOS password to get to this point.
So for Linux and Mac, if you set no BIOS password but do have an OS password,
the laptop might report its location while the thief is sitting there trying to guess your
Let's look at fundamentals:
What is important to you ?
What are you trying to protect or prevent ?
- Prevent your device from being stolen.
Solution: physical security (locks, cables, lock-box, etc).
- Prevent a thief from reading your data.
Best solution: full-disk encryption, either via hardware (built into the hard drive)
or software (such as TrueCrypt
Wikipedia's "Comparison of disk encryption software",
Martin Brinkmann's "List of TrueCrypt encryption alternatives",
Lifehacker's "How to Encrypt and Hide Your Entire Operating System from Prying Eyes",
Micah Lee's "Encrypting Your Laptop Like You Mean It",
Chris Hoffman's "Why a Windows Password Doesn't Protect Your Data").
The software approach offers several alternatives and gets a bit confusing;
hardware encryption is the wave of the future.
Dan Goodin's "Western Digital self-encrypting hard drives riddled with security flaws"
Joseph Cox's "Some Popular 'Self Encrypting' Hard Drives Have Really Bad Encryption".
A more limited solution: keep your most critical data in an encrypted text file
(perhaps by using NotepadCrypt or something similar).
Bitlocker, 7-Zip, AxCrypt also can encrypt individual files or sets of files.
How-To Geek's "How to Encrypt Your Android Phone and Why You Might Want To"
Eric Ravenscraft's "The Essential Android Security Features You Should Enable Right Now"
On iPhone, just set a passcode and everything gets encrypted automatically ?
Apparently, some smartphones must be jail-broken if you want to encrypt just specific
folders, not encrypt or password-protect the whole phone.
Password-lock your device, unless you're using a theft-recovery product that prevents this.
Most of the theft-recovery products listed on this web page give you a "delete" or "shred"
capability: when the thief connects to the internet, a command comes from the
central site and all data on the hard disk is deleted. This prevents the thief
from reading your data. But it works only if the thief connects to internet before
trying to read your data, and if they haven't disabled the theft-recovery software somehow.
Whitson Gordon's "How to Break Into a Windows PC (and Prevent It from Happening to You)"
- Avoid losing your data.
Best solution: back up your data frequently, and don't keep the backups next to the laptop.
- Avoid future losses.
If your device contains account and password info, identity info, info about your family and friends,
after a theft you'd have to take steps to avoid further damage. You'd have to change passwords, put out monitoring or alerts to prevent
identity theft, contact other people at risk, etc. What else is on the stolen device ?
Apps with registration codes or passwords stored in them,
email in-box with account and password data, bookmarks ditto, cookies, any data files you use to record accounts and passwords,
any BAT or CMD files with account/password in them.
Perhaps now, before any theft, you should evaluate your device. Does it
contain sensitive data that really doesn't need to be on there ? Or should
that data be encrypted ? Does the browser contain cookies that will give instant access to your email and Facebook accounts ?
After a phone or smart-phone is stolen, if you don't want to try theft-recovery, immediately report the theft to
your carrier, to avoid huge call charges. Do it immediately; you are liable for calls made until the time you report the theft,
and some gangs will make thousands of dollars of calls as quickly as they can after stealing the phone.
Double-check with your carrier to make sure they received and recorded the report of the theft; probably
a good idea to call them again and confirm it
Maybe report it online, and then call to confirm ?
Ask them to send an email confirmation to you.
A handset PIN doesn't protect you if the thief moves the SIM to another device.
- Get your device back.
Solutions: etch your contact info onto the case of the device, inside
Use the theft-recovery software listed on this web page.
Keep a record of make, model, color, and serial numbers.
Probably a good idea to have digital pictures of the device, front and back,
to give to police.
Display your contact info on the lock screen or login screen or physical label, so if a Good Samaritan finds
your device, they can return it to you.
After a theft, report the theft to police, and
report the theft to the manufacturer (they'll probably require a copy of the police report).
Maybe report it to online databases, such as
Put up fliers in the area where it was stolen, offering a reward for return ?
Look for it on Craigslist or EBay, maybe in the section for your local area.
Also: the "devices" you need to protect include your computers, tablets, phones and
backup media (external disks, tapes, flash drives, hard copies).
Privacy Alert's "Computer hardware privacy"
Mobile phone security:
[Do I have this right ?]
Three things to protect: your data
, your device
, and access to the service
(ability of thief to make calls and run up bills on your account).
Having a passcode/PIN set prevents thief from using your phone, even with another SIM inserted.
[But is there a hardware reset that wipes everything and sets back to defaults ?]
- If phone has a SIM card, disabling service after the theft
is your only protection on access to the service.
Having a passcode/PIN set on the device doesn't stop thief from popping out the SIM card and using it in another phone.
But: some SIM cards do have a separate PIN for the card itself.
- If phone has no SIM card, having a passcode/PIN set will prevent thief from using the service.
What "location" information do you get once the thief has logged in and connected to the internet ?
You'd get the IP address. Maybe also the Wi-Fi or Ethernet network name ?
If your stolen device had a GPS in it, you could get latitude/longitude.
If your stolen device connects via cellular data-modem, you could get approximate latitude/longitude.
Software could use the list of visible Wi-Fi networks to calculate approximate latitude/longitude.
From the IP address, you could find the ISP's info, and contact them.
If the IP address is specific to a person or house, the identity of the thief is fairly clear.
But if the IP address maps to a public Wi-Fi spot (such as provided by a school or library or McDonald's or Starbucks),
or a private house that's running an open Wi-Fi signal, the identity of the thief is unclear.
Most products can use the laptop's webcam to take a picture of the thief, which helps.
The companies selling the commercial theft-recovery products may assist in the tracking and recovery process,
helping you follow the IP address, contact law-enforcement, etc.
Some users who had devices stolen report great cooperation from law-enforcement in recovering their property;
others report that police were uninterested in
helping them. Probably varies from town to town and country to country, and also depends on how much
info you can give to the police.

Maintain a secondary email account, preferably on a different provider from your primary email.
If something happens to your primary, you can use the secondary to send critical messages until
you fix the primary.
Don't ignore the account-recovery settings on your accounts, or put bad data in there.
Sure, you'd rather not let Google or Yahoo or Facebook know your phone number or your second email address.
But that information can save you if their security triggers get pulled for some reason.
You travel, you try to access your email, you get "hey, we see a login attempt from a known-dangerous country,
we're turning off account access until you give us the code we're SMSing to your phone or emailing to your other account".
Better hope you've kept the account-recovery options up-to-date.

And not just what's on your hard drive.
trust the cloud!
Google recently ended my account for an unidentified TOS violation. I am not sure what I did.
I just logged into gmail one day and instead of an inbox I saw a message saying my account had been disabled. I lost:
8 years of email contacts
6 years of favorited YouTube videos
About a dozen videos I made with my brother that were uploaded to YouTube.
All my Drive/Doc files including original writing.
My passwords to several sites, including banking and insurance sites.
Three albums I had purchased from Google Play.
Here's the kicker: I was a google believer. I am one of the 5 or so non-developers who actually owns a first generation Chromebook.
I believed in the cloud!
Use and enjoy Google's services, but do NOT rely on them. Even though you buy their computers and purchase music from them,
you are STILL not the consumer with google. You are the product (sold to advertisers).
So when you are shut out from their garden, you have no customer service to appeal to, or to even
find out why you got tossed. You might as well be staring at an angel with a flaming sword, wondering where your pants are.
> Didn't you contact Support ?
When you get the "your account has been disabled" screen, they give you a link to voice your grievance.
After submitting, you get a message that says something to the effect of:
"If we find we have reason to contact you, we will contact you."
You can also go the community forums and plead for help. Sometimes someone associated with google
will actually say: "I'll have people take a look at this." In all my pleas, I never got a response.
That is as far as support goes. You are not a customer. You are the product, and you are merely a commodity.
Have you ever heard of "commodity support"?
From someone on reddit
A few days ago my Facebook account was disabled suddenly and without warning.
I've gone through what I thought was a fairly routine appeals process - filled in the form they link
you to when you try to log in and included a scan of my photo ID as they requested to prove I'm a
real person etc. However, I just received an email from Facebook saying the following:
> ... Upon investigation, we have determined that you
> are ineligible to use Facebook. ... Unfortunately, for
> safety and security reasons, we cannot provide
> additional information as to why your account
> was disabled. This decision is final. ...
This is really bizarre and quite upsetting - it's easy to forget just how much we rely on this service.
If I can't get my account reactivated, that's six years of content (and memories) lost,
and a huge blow to my ability to keep in contact with some friends and family.
The only possible reason I can think of for my account being disabled is what I was doing at
the time - sending some photos to someone through the private messaging system.
Some of the photos were (mildly) adult in nature (at her request!) which could be deemed
a breach of the Community Standards if you look at it in strict black and white terms
("Facebook has a strict policy against the sharing of pornographic content").
However I can't bring myself to believe that there is someone monitoring private message
attachments and instantly banning people if they see boobs. Beyond that, I genuinely
can't conceive of a reason as to why my account was singled out for anything.
Any advice would be appreciated as to what I should do next - I am not yet willing
to just give up and lose all of that content. I have replied to the email, though I
doubt anyone will read it, but beyond that there's really no other contact options
I can see, and Googling this problem does not produce much beyond more horror stories like this.
From sugarbreach on reddit
I am writing this to warn Google users to back up their data, and to realize that everything
you take for granted can be taken away in an instant.
About a week ago I attempted to log into my Gmail account and was greeted with a page
saying my account was disabled. It says that it was disabled due to a perceived violation
of the terms of service and product specific polices. I have read and reread the google terms of service,
and I know I haven't done anything to violate them. The only possibility I can think of is that someone
may have hacked into my account. I have been an enthusiastic gmail user since it first came out in beta,
and you had to be invited to get an account. I have relied on google apps to make my life easier.
I have filled in their account recovery form, and even tried calling members of the Gmail team, but have had no luck.
I also have posted on the gmail help forum, but an expert there said he contacted google and there was nothing
he could do and google wouldn't tell him anything "for privacy reasons".
This has created the ultimate real-life nightmare, and has turned my life upside down, a few examples of which are listed below.
All of my contacts were linked to this account. I now do not have access to emails, phone numbers, addresses, etc.
My google voice telephone number is no longer working. I had this phone number on my business cards and email signature,
and now when someone dials the number, they are given an error recording. "We could not complete your call, please try again".
My youtube account with many videos I cherished of my children are now gone.
I have all of my photos backed up to the account for nearly my entire life, as I thought this was the safest place to keep
them (the cloud!) I have photos of my beloved grandparents who have since passed away, and the thought that I can no longer
access these photos makes me sick. I also have thousands of pictures from vacations and of my children that I fear are gone forever.
A nice chromebook that I purchased to access all of the google apps is now almost useless since my account has been disabled.
I have multiple documents in my google drive that I have spent hours of work on, and can no longer access them.
I placed an enormous amount of faith and trust into google's products and services, as millions of people have worldwide.
It is a shame that something this important in someone's life cannot even warrant a response from a live person at Google.
I have been very depressed because my entire life was encased in google's products, and now everything is gone.
Again, I am writing this to warn others that this can happen to anyone at any time, so it would be wise to back up treasured
items in your google account. Ironically, google provides the means to do this through their "takeout" app, which I did not
learn about until after my account was disabled. If there is anyone out there reading this that can offer any guidance
for getting my account reinstated, I would sure appreciate it!
If you lose a cloud account, you can lose stored data, remaining time on a subscription, any accumulated credit or gift cards, network link that
makes some device (such as Amazon Echo) work.
Maybe some people don't consider their email to be "cloud data", but it is. If you're saving 10 years of past
emails in GMail or Hotmail or something, it may be valuable to you, and it may be used by a hacker if your account gets hacked.
It's also hard to back up. I'm a big believer in keeping your email account as close to empty as feasible.

From someone on reddit:
The basic methods of "hacking" accounts are:
- You forgot to log out.
- Guess the password. Many people have incredibly simple passwords and guessing can work.
Many websites have some kind of measure against repeated guessing (e.g. captchas).
I think Facebook's countermeasures are good enough that pure guessing can rarely work on that specific site.
- Find your password in a list of leaked username and passwords. Often when there is a breach of a huge database
the list ends up on the Internet and people who want to hack you can search for your name, e-mail and common
usernames to see if your password has ever been leaked. If it has they can try that password and it will often work,
or sometimes a simple change to your password will work.
- Guessing your secret questions. Often the answers can be learned from just searching your Facebook
or other social media accounts, or at least it can be narrowed down to a small list.
- Tricking you into entering your username and Facebook on their website. Maybe they send you
an e-mail that claims to be from Facebook and gives you a link that looks to be from facebook where
they want you to log in. For example they may say that your account was compromised and that they
need you to log in to verify your details. Another common one is that they claim that you've won something,
but you just need to log in with your facebook credentials to verify it.
- Calling customer support claiming to be you and asking for a password reset saying that you
have lost access to your account and e-mail. This is especially useful if they can find a lot of
information about you online so it seems like they're really you. Often a lot of what they ask about
has already been leaked in another breach. This can sometimes even get around two-factor authorization.
General security and privacy issues:
Costs of counter-measures:
[Generally from most likely to least likely:]
- Your own actions. (The biggest threat of all. You accidentally post something private in the wrong place,
expose a password, mis-configure your device or account, lose your device, accidentally delete your data, trust a scammer.)
- Your family, friends, associates. (They post about you, snoop on you, accidentally leave your house or car unlocked,
mis-configure their device, accidentally delete your data, trust a scammer. They expose their Contacts list, which contains
your name and email and address and phone number and birthday. They tag you in Facebook photographs, or
mention that you were with them at some wild party.)
Your browser history
- Your ex-spouse, former friends who now are enemies, former coworkers who you fired or angered.
(They may be highly motivated, but probably don't have access or skill to cause high-tech harm.
Unless you forgot to change the passwords they know. But they may have private info they could post.
Cyrus Farivar's "If you're a revenge porn victim, consider this free, helpful legal guide")
- Your software. Some application or web site you use may be sending your data to somewhere
else that you don't know about (some apps harvest your email address book or phone contact list or Friends list).
Or storing your data in an unsafe way in a server.
- Corporations selling your meta-data or data to advertisers.
- Corporations reading your data to enforce their contract rights (terms of service) and maybe look for criminal activity.
- Organizations accidentally exposing data you've entrusted to them, through careless practices or by getting hacked.
- Data criminals and hackers. (Identity thieves, credit-card thieves, blackmailers, ransomware, etc.
Hackers who want to use your device as part of a botnet. And you may be a special target if you
have something valuable on your computer:)
Laura Shin's "Hackers Have Stolen Millions Of Dollars In Bitcoin -- Using Only Phone Numbers"
Alex Hernandez's "Chase eATM user has mobile app hacked and loses $3,000"
- Casual snoops or thieves. (Although with snooping software, "casual" capabilities are increasing.)
- Law enforcement (recording everyone's activity, such as cell-phone locations and car license plates).
- Internet vigilantes or lynch mobs or public shaming.
(E.g. someone decides a picture shows you abusing your dog, and whips up a mob to punish you.)
- Private investigators and lawyers. (They have some access to government databases and powers.)
- Law enforcement (specifically targeting you).
Jonathan Zdziarski's "Protecting Your Data at a Border Crossing"
Andy Greenber's "A Guide to Getting Past Customs With Your Digital Privacy Intact"
- Foreign government intelligence agency. (Highest technical ability, but no legal authority.)
- Government intelligence agency. (NSA, DHS, etc. Highest technical ability, PLUS legal authority.)
No matter what protection you propose, some people will say "oh, the NSA has cracked that !". First,
how do they
know ? Second, a counter-measure still may be worth using even if the NSA could crack it;
NSA is not the only threat or main threat. Third, just because NSA could crack something, doesn't mean they
would spend the resources to crack your
And some people say "trust no one !". Well, I think it is reasonable to trust the CPU chip vendors,
and the compiler-writers. I don't see how useful "backdoors" could be built into those things (and I have BS and MS
degrees in Computer Science). Trusting the OS vendors
is a little more dubious; I guess I trust the basic OS, but maybe not all of the standard apps and services
supplied with them. Same for trusting browser vendors.
Of course, if you trust no one
, you'll never be able to get anything done.
Can't drive my car, because I shouldn't trust the manufacturer.
Better not eat anything, because I shouldn't trust the food companies or stores.
Some people say "it's all over, we've lost our privacy, it's done". No, it's an arms race,
and right now consumers don't have very good weapons. We need to get convenient, good, routine encryption.
We need more sites, applications, and protocols designed with security and privacy as priorities
from the foundation up. Maybe "mesh" networking, peer-to-peer systems, distributed systems
(SCG's "6 Anti-NSA Technological innovations that May Just Change the World"
We in USA need better regulation of spy agencies, via FISA and Congress.
It's not over. You're generating new private data every day; you can protect that.
And you can create fake data.
A worrisome trend: intelligence agencies being pressed to use their powers for non-intelligence purposes.
From Alex Hern's "David Cameron: GCHQ will be brought in to tackle child abuse images"
"GCHQ [the British intelligence agency] will be brought in to tackle the problem of child abuse material
being shared on peer-to-peer networks."
From NSA spokesman quoted in Barton Gellman and Ashkan Soltani's "NSA collects millions of e-mail address books globally"
"[The NSA] is focused on discovering and developing intelligence about valid foreign intelligence targets
like terrorists, human traffickers and drug smugglers."
Eric Boehm's "Reuters: Law enforcement use info from NSA phone database to go after common criminals"
Conor Friedersdorf's "The NSA's Porn-Surveillance Program: Not Safe for Democracy"
Patrick Howell O'Neill's "Dealing with the digital afterlife of a hacker"
- Makes system harder to use. (Extra steps to do things, more software to install and update, etc.)
- Performance penalty. (Encryption takes cycles. Tor and VPNs impose multiple hops.)
- Worse results. (Such as worse search-engine results if you use something other than Google Search.)
- Have to get other people to use it, too. (Biggest problem with using encryption on email, or using
a social network optimized for privacy.)
- Can't use some features. (To use Tor browser for best privacy, I think you're advised to
Seth Rosenblatt's "NSA tracks Google ads to find Tor users".
If you turn off location-tracking on your phone, you lose some features.)
- Reduced reliability or recoverability. (If your disk is encrypted, and some key sectors go bad, the
whole thing may be toast. There are many recovery tools for non-encrypted disks.)
- Greater dependence on fewer vendors. (If your encryption vendor or encrypted-email service goes bankrupt, what happens ?
And if you demand good encryption or privacy above all else, maybe you can't use the most popular and best services.)
- Money and time costs. (For example, some people say you should run your own domain and email server. Sounds like a lot of work.)
How to attack cryptography:
- Best to do encryption/decryption at the extreme ends of a transaction, not on
short segments in the middle. (But even that can be defeated by a keylogger.)
- Peer-to-peer architecture better than central-server architecture. (So no one can grab all of your data by going to one place.)
- Don't put really private or valuable stuff on electronic devices, or on internet.
(There is no such thing as total privacy or perfect security.)
[From hardest to easiest:]
- Find a flaw in the mathematics (extremely unlikely).
- Find a flaw in the algorithm.
- Find a flaw in the crypto software.
- Brute-force password-guessing.
- Find or create a flaw in the surrounding software (operating system, networking, key-logger, etc).
- Find a flaw in the configuration (software not updated, password not set, place where data is not encrypted, etc).
- Human problems (password exposed or easily guessed, social engineering, etc).
- Legal tools (warrant or subpoena to get encryption keys or tap traffic).
- Put tape over cameras when you're not using them, or have the phone camera facing down onto a desktop.
- Turn off devices when you're not using them.
- Use external drives for really sensitive data, and unplug them when not using them.
- Don't put really critical stuff on networked devices if you don't have to.
- Don't have very sensitive conversations in front of devices with microphones.
- Pay cash for things when possible.
- Shred any trash that has your name, address, phone number, email address, and/or account number on it.
Things that may not increase security and privacy:
- Private browsing in your browser.
This just prevents your activity from being recorded in the History in your browser,
so the next person who sits down at your computer and uses your browser won't see a record
of your activity. It does nothing to prevent spying on your activity as it travels across the internet.
- Full-disk encryption.
This prevents someone from stealing your computer and reading your disk.
But once you sit down at your computer and enter the password for the encrypted disk,
the decrypted contents of the disk are available to all of the software on your computer.
So a virus or malware could access the data on the disk, send it out over the internet, etc.
If you get up and someone else sits down at your computer, they have full access to your data.
New things we need to increase our privacy or security:
- To use when someone (law enforcement) is forcing you to surrender your password:
Ken Kinder's "The travel-only Gmail account: A practical proposal for digital privacy at the US border"
- Dummy access password: a special password that you enter, and the device or account gives access to
only a special "dummy" version of the data.
Known as "plausible deniability encryption" ? Maybe Veracrypt
provides something like this on desktop OS's ? Maybe smartphone app "Protect My Privacy" does this ?
- Self-destruct password: a special password that you enter, and the device or account wipes itself clean.
(Note: factory reset probably doesn't overwrite all data, just removes pointers to it.)
- Limited self-destruct OS password: a special OS login password, and browser cookies and selected files get deleted as
you get logged in.
Quincy Larson's "I'll never bring my phone on an international flight again. Neither should you."
- End-to-end encryption, running on the client machines, so the service companies (Facebook, email service, etc)
can't read our data and can't surrender it to law enforcement.
- A "privacy noise-generator":
At random intervals, it would do random searches, page-hits, chats, VOIP calls, pings.
Millions of people would run it routinely, and generate traffic that would obscure the patterns
of real activity. A government or company trying to analyze our traffic would have
a more difficult time separating the real and false data.
