Data Mining: How Companies Know Your Personal Information
- Three hours after I gave my name and e-mail address to Michael Fertik, the CEO of Reputation.com, he called me back and read my Social Security number to me. "We had it a couple of hours ago," he said. "I was just too busy to call."In the past few months, I have been told many more-interesting facts about myself than my Social Security number. I've gathered a bit of the vast amount of data that's being collected both online and off by companies in stealth â€” taken from the websites I look at, the stuff I buy, my Facebook photos, my warranty cards, my customer-reward cards, the songs I listen to online, surveys I was guilted into filling out and magazines I subscribe to.
