Q&A: The scary details of what Facebook knows about you

By | May 31, 2012, 10:03 AM PDT

02.LapTop.Cosi.Dupont.S.WDC.3dec05

Google and Facebook deal in data. Our intimate data, information about ourselves from sexual quirks to why we hate our boss to our divorce plans. We hand over such secrets willingly and gleefully to online networks and search engines as if it were over coffee with a close friend in our kitchen. Yet within these social networks, which give us the false impression of privacy, many people are watching, analyzing and using the details of our lives. And our revelation has serious consequences.

Europeans can request Facebook to hand over all the information it has on them, sometimes 1,600 pages worth. But Americans have no such right. And it looks like that’s not going to change anytime soon according to Lori B. Andrews, professor of law at IIT Chicago-Kent and author of the book, I Know Who You Are and I Saw What You Did: Social Networks and the Death of Privacy.

SmartPlanet spoke with Andrews to get the details on just how much we are giving up.

SmartPlanet: You’ve mentioned that the magnitude of online information Facebook has about us is stunning. Do we know exactly how much Facebook knows?

Lori Andrews: In Europe people have the right to find out what companies know about them. When an Austrian law student asked Facebook what information they had about him Facebook sent him a CD ROM with over sixteen hundred PDFs on it. So that gives an idea.

SP: But Americans do not have a right to know what Facebook has on us?

LA: Right. Security analyst Richard Power said Facebook will soon have the most private information on a billion people. If the government tried to get that information, like political beliefs, sexual orientation, emotional status, he said it would take money, lawyers, and maybe even guns. But we just turn it all over by posting to Facebook or by doing Google searches and using e-mail.

Ninety-three percent of the time when the government asks Google for information, they turn it over.

SP: How much money is Facebook making off our data?

LA: They make 85 percent of their income, or $3.7 billion annually off of people’s private information by targeting ads to people based on their individual likes, dislikes, and plans. Google makes 10 times that much money by collecting information about people through scanning Gmails and Google searches.

SP: And the upshot of monitoring everyone’s personal information leads to some astonishing outcomes.

LA: Yes. In 2010 Google admitted that when young people revealed on a Google chat board that they were thinking of committing suicide with “x” chemical, ads would pop up with a 1-800 number for that chemical.

SP: How has it gotten so open?

LA: One of the problems is that federal law doesn’t apply when one party consents to providing the information. The courts say that it’s okay as long as one party has given consent.

SP: Who is the party giving consent?

LA: If the Web site gives consent to tracking mechanisms or if your service provider gives consent, then you don’t have any recourse against the data aggregator.

SP:  Has the law just not caught up with the speed of the technology?

LA: There have been various technologies that invaded privacy, like the portable camera, forensic technology, testing technologies, and in every case even though the law initially allowed invasions in privacy, eventually the courts stepped in to protect privacy. But in the case of aggregating data on individuals the courts have thrown up their hands and said things like, “Oh e-mail is like a postcard.” Courts seem to misunderstand how the Internet works. They seem to think everybody should just assume that whatever they do on the Internet is public and not private.

It’s as if there was a part of a city that has a high rape incidence and we say, “Oh women who get raped there can’t prosecute.”

SP: How does data from our online behavior gets translated into targeted ads? Presumably some may argue this is a good thing, to get ads that actually relate to our lives.

LA: Sure, some might be beneficial. If you like certain band you might get an ad about the band’s schedule. Or you might get money off at your favorite clothing store.

But there’s also a dark side. For example, if I reveal over Gmail that I’m about to get a divorce I might be denied a good credit card because that company claims that people who are getting divorced tend not to pay off their credit cards.

SP: This idea of aggregate data sounds pretty dangerous.

LA: There is never a context for the aggregated data. If I’m searching for an illness for a friend or relative, it’s assumed to be information about me.

Then if I later go to a life insurance Web site I may be denied life insurance because it is assumed that I’m sick. Finland actually passed a law that said you can’t Google job applicants. And Germany is considering a law that says you can’t use social network information about job applicants.

SP: How are they going to monitor such laws?

LA: It’s difficult to monitor any employment law such as discrimination against gender.

And think about how many federal laws you’re going to evade as an employer by using social network information. For example, you’re not supposed to be able to ask under the Federal Pregnancy Discrimination Act whether a woman’s intending to get pregnant when you do a job interview. But if you look on her Facebook page and she says, “Hey we just made an appointment with the fertility doctor” or “Got married can’t wait to start a family,” you get that information.

I think that it’s shocking to most people that now seventy-five percent of employers require their human resources officers to look at the online presence of job applicants.

SP: And most of us are posting and searching with a false perception that nothing is being documented, right?

LA: Part of the legal analysis of whether privacy is protected is whether people have an expectation of privacy. Social networks give us an expectation of privacy. You have to “friend” people. You share your most intimate details. You hate your boss, you hate your spouse, you talk about your sex life, your sexual orientation, your political beliefs. It’s all the stuff we routinely protect in other settings. I do think there’s a good case to be made that because of its structure Facebook is a private place, not a public place.

If I had twenty-five or a hundred people over at a party at my home the police couldn’t get in without a warrant, my boss couldn’t attend or monitor conversations unless I invited him. I would like to see a social network be considered our online home and protect it as much as our regular homes.

Justice Alito suggested that by using social networks we’re pulling the rug out from under our own rights because we’re creating the impression that people don’t expect privacy. I think that’s completely wrong.

SP: So everyone should start paying more attention.

LA: Yes, pay more attention to what’s on your Google Dashboard. And check out companies like Acxiom, where you can go on the Web site and put in three pieces of information about yourself and find out what assumptions they are making about you.

SP: What else can we do?

LA: I think we need to push for increased rights to privacy, but I also think that searching in incognito mode or clearing your searches are important.

And then there are also concerns about people cyber-casing people who post their new engagement ring and if the photo is taken at their house, it’s easy to figure out where they are. There were 50 robberies by a New Hampshire gang that just kept track of who was on vacation according to their Facebook status updates.

SP: So we have to be a lot more vigilant.

LA: I just took a look recently at a patent that allows me to hold up my smart phone to a stranger on the street, and it will tell me through facial recognition if that person has a blog, a profile on a dating site, their status, etc. It’s important to know that your digital self is becoming more important than your offline self. Increasingly technologies are being designed with privacy invasion in mind.

Welcome to a Brave New World
Power corrupts and absolute power corrupts absolutely. We shouldn't believe that Google will "do no harm", or Facebook wants to bring the world together. These companies are public and, hence, required to maximize profits. Profit comes by selling our info that we provide freely. The tough decision is when does the freedom of unlimited information impact our person liberties? I fear it must get worse before it gets better. The old adage, be careful what you say couldn't be more important today as when your parents told you it as a child!!

If you want to stop the invasion of your privacy, block their ads
If you want to fight this invasion of privacy by Google and others, block their ads. You can do this by installing the Adblock Plus extension for Firefox and the AdBlock extension for Chrome.

You can't stop these companies from tracking you and selling that info. But you can stop the reason for it. If you don't see the ads, you can't click on them or even download them, and as a result Google and Facebook will get no revenue. If even 5% of users install ad blocking software, it will be felt.

People will say ads are what keeps most of the internet free. How much is your privacy worth to you? Once internet companies adopt sane policies regarding privacy, these extensions can easily be disabled or removed.

Ads based on surveillance
"In 2010 Google admitted that when young people revealed on a Google chat board that they were thinking of committing suicide with 'x' chemical, ads would pop up with a 1-800 number for that chemical." Google executives should have been charged with a crime for posting ads assisting people in committing suicide. Given that internet users' privacy is gone forever, Facebook, Google etc. should at least be regulated by legislation that would ban such ads, and they should only be able to allow ads that could help rectify the situation. It would be much better to promote a distress center number.

Well..
If I write to a friend that I'm, allergic to peanuts then Google ads will post an ad for peanuts.

If I write to a friend that I love peanuts it will post an ad for peanuts.

It's a simple algorithm with no malice. Google executives did not post ads.

Privacy?
So let's see. A person posts all kinds of information about themselves to be read by almost anyone.
That same person then expects privacy.
Sorry Campers, you can't have it both ways.

Burglaries, not robberies
"There were 50 robberies by a New Hampshire gang that just kept track of who was on vacation according to their Facebook status updates."

If the residents were on vacation, these were burglaries, not robberies.

Acxiom?
It's not readily apparent where one goes on the Acxion website to "put in three pieces of information about yourself and find out what assumptions they are making about you." Any more concise instructions would be helpful.

This may help?
go to the global home page. At the top or bottom there is a category called, Ideas and Innovations. Click on it. Then click on the self assessment tool category. The third tool down, the one at the bottom will give you an idea of what demographic cluster you fall into based on your answer to 3 or 4 simple questions,. This may or may not be what your looking from what I could gather thumbing through the site its for business purposes and not so much on the individual. Understandable, given what they do. Hope this helps, and if you do find more useful information there please post it .

Sounds Like Another Big Bank Money Scam
Sounds Like Another Big Bank Money Scam The Wicked Are at it again

Will Facebook soon start to go under from another new rival soon to be. Facebook looking for suckers to lose their money or should i say give their money away to them, the wicked. Sounds like another Big Bank Scam. Selling to slow in the head investors soon to be a lot of Worthless Paper. Sounds like Facebook is not selling but are stealing all the money they can and a lot of it tax free.

The wise and smart will read the bible and get to know our Lord and Savior Jesus Christ.

If someone really cares for giving out info, give them a Bible with red letter print. That is a red letter edition words that were spoken by are Lord and Savior Jesus Christ. With a Pray for them the lost maybe they will be saved, and not go to hell.

You want to make Money install Solar Energy. Why keep giving your money to others.

Pray your Name is in the Book Of Life not Facebook!

Facebook sells your info to the wicked!

Online privacy can happen
It's great to hear people talking about data gathering and online privacy issues. But I wish people would talk more about the options that are available to protect your privacy online.

Online privacy is possible - you can use TOR or the company I'm working with called Cocoon makes everything you do online private and secure. There are probably others - search for online privacy and you'll find some options!

Blame for the problem - incompetent advertisers.
In spite of all the so called information FB has - is it really that accurate in describing our interest and needs? Based on the ads I get - the answer is simple - a resounding "No." If they aren't getting the ad subjects correct, then there is no possible way to correlate an erroneous subject to a remotely accurate purchase timeline for that non-existent purchase potential. So, the question is begged why do advertisers pay for for information that has extremely low sales predictability? That's relative simple as well, most advertisers don't accurately track ad/sales responses. Sales unrelated to ads are often tallied as being generated by ads that actually had zero impact on the purchases.

This was the wake up call that GM got regarding their ads on FB. When they tallied FB ads and FB ad generated sales correlations - there was zero correlation. If you think GM just screwed up their ads, you would be wrong. The shocking truth is that they are one of the few companies that actually accurately track their ad results.

On the other hand, G with it's search engine can 100% qualify the results of individuals search engine product queries. Consequently, people that search for specific products are prequalified as interested and with a high probability because of shopping and especially a there is a comparison of products. A totally different level of stat quality than what comes out of FB chat filters and "likes.

If you don't like FB's approach of filtering your comments for potential product leads - just make a list of popular products and periodically post them, on your FB site and then use those product names in your spam filter blocker. If you can't stop the filtering - you can plug up the filters and make their results even more meaningless.

ACXIOM and how to test their assumptions about you
(1) Go to ACXIOM.
(2) Click on "Ideas and Innovation"
(3) Click on "What's your cluster?"
(4) Enter your correct information on the form that comes up.
(5) Check out Acxiom's assumptions about you.

Note: This information you entered is not retained by Acxiom after you leave their page.

Their assumptions about me were only about 25% correct. The other 75% was WAY off in terms of their assumptions about our interests, lifestyle, and what we did in our everyday activities. I sure wouldn't hire them to help ME with target marketing strategies! If the percentages had been reversed, I might, but that isn't the case. They simply missed the mark by a mile. Try it for yourself and see what your opinion is of their ability to forecast how people will fit into target categories.

What's your cluster
LOL

"Cluster 5 households are wealthy empty nesters" Duh, I just put in an age over 50 and said there were no kids and a six figure income. Du-uh.

"they are extremely well educated and still well compensated (ranked seventh for household income) in professional and managerial white-collar jobs" Well, not "extemely" and not well-educated.

"Cluster 5 households are well established in their communities. " Meaningless, unless "well established" is defined.

Nothing else in their Cluster 5 definition is true at all.

Fair Trade
"They [Facebook] make 85 percent of their income, or $3.7 billion annually off of people???s private information by targeting ads to people based on their individual likes, dislikes, and plans. Google makes 10 times that much money by collecting information about people through scanning Gmails and Google searches."

Users trade their information, preferences, and experience to Facebook and Google in exchange for free e-mail, social networking, and Internet searches. That sounds like a fair trade to me.

If you don't like them making money off of your info... don't use their free products and services!

Facebook and Google know very little about me. I don't use Facebook at all, and I very rarely use Google, and don't use Gmail, or plus, or Chrome, Android, or any other Google product.
