What Data Mining Firms Know About You

storagedude writes "Time writer Joel Stein spent three months learning what data mining companies know about him. After learning everything the companies had profiled about him (some of it inaccurate) — social security number, age, marital status, religion, income, debt, interests, browsing and spending habits — he had a surprising reaction: complacency. '... oddly, the more I learned about data mining, the less concerned I was. Sure, I was surprised that all these companies are actually keeping permanent files on me. But I don't think they will do anything with them that does me any harm. There should be protections for vulnerable groups, and a government-enforced opt-out mechanism would be great for accountability. But I'm pretty sure that, like me, most people won't use that option. Of the people who actually find the Ads Preferences page — and these must be people pretty into privacy — only 1 in 8 asks to opt out of being tracked. The rest, apparently, just like to read privacy rules."

      Trust doesn't necessarily come into play. I expect corporations to make money off of me. I'd rather they do that by presenting me with ads I'm interested in. I trust them not to steal my identity insofar as if they're already breaking the law, adding new laws isn't going to change anything. Last year I got a great deal on my laptop because whatever profiling they were doing decided that I was in the market for a laptop. Instead of paying $1000 for a $1000 laptop like I was planning, I got a $2500 laptop for $1000. As far as Im concerned it was win-win - I got a great laptop, and they got my money.

      Although I am all for targeted ads, but it is a lot more likely that you have paid $1000 for a $1200 or even a $900 laptop. Shockingly, few retailers are willing to sell items at less than 50% of their price. Not unless they triple the retail price first.

    That's probably because people who are into privacy know that opting out will most likely show up in somebody else's DB as another data point, i.e. somebody who's concerned about privacy.

      Maybe it's my internet marketing background, but when I read about a 12% conversion rate of interested people reaching a page, I don't think "hey, these people don't want to opt out," I think "hey, this website has some serious usability issues."

      Here's what I experienced: Found the opt out page, hit select all, and clicked submit to opt out. I was taken a page with ~50 little messages saying "You have successfully opted out from this network." It wasn't until I scrolled down to the very bottom (passed all these messages) that I found the notification: "Please click continue below to confirm the results of your opt out requests."

      Despite clicking "submit" and getting what looked like 50 success messages, nothing was actually saved until I clicked an innocuous link on the next page! One gets the impression they're not trying very hard.

  5. Missing the danger... by Shoten · · Score: 5, Insightful

    The problem isn't what the data mining companies would do with the data, themselves. I don't think it's even with what companies who buy their services would do, frankly...although I know that on Slashdot that may not be a widely-held or even popular belief. What's dangerous is that the data mining companies also provide data to the government. And why is that? Because the data mining companies collect and compile data that our government is forbidden from collecting directly without having to get legal authorization (like a warrant, for example). It's a workaround that circumvents controls meant to protect the privacy of individuals from their own rulers. Of course, I'm speaking from the perspective of someone in the USA; when it comes to civil rights, your mileage may vary.

      What's dangerous is that the data mining companies also provide data to the government

      In some cases, these firms are actually getting data from the government. I don't exist on facebook, twitter, myspace, linkedin, or any other social networking site. Yet at least one of these companies has a fair bit of information on me that they are showing off to the public; my full name, my approximate age, my physical address, my marital status, the number of people in my house, etc. I've also never had a land line in my house, so there was no way to get any of that from a phone book either.

      Now if you are really finding that these companies have significant information on you that isn't available through the government, that would be a different matter.

  7. The threat is in the potential by Toe,+The · · Score: 4, Insightful

    The threat isn't what they are going to do with your data; it is the potential that it presents.

    Sure, there is no reason why they are going to one day say, "Hey! Let's look at So-and-so's record and see what we can do to him as a result."

    However, what can happen is that one day you become a "person of interest" to someone somewhere for some reason (quite possibly entirely by mistake). Then you can expect that that entity is going to buy all the data they can on you and sift through every detail of it.

    And don't forget that once this data exists, it pretty much never goes away. Terabytes are incredibly cheap these days, and data companies most likely invest in lots of backup and redundancy.

    P.S. For kicks, also think about what may happen if such a company gets hacked. Enjoy.

The evil that a company does is (usually) an emergent property. It's not enough to trust the people -- you have to trust the structure, and for any large for-profit company that's a very foolish thing to do.
