Facebook collects more data than you might realize. You probably didn't know that it receives a report every time you visit a site with a Facebook "like" button, even if you do not click the button, even if you are not logged in, EVEN if you are NOT a Facebook user. It's collecting all sorts of info, including your IP address, which, in the words of Lori Andrews, a law professor at the Illinois Institute of Technology, can act like "DNA at a crime scene. There often will be enough data points connected with your IP address to clearly identify you."
They know what you look like. The "Tag Suggest" feature, which was enabled for some users, without notification, scans the photographs that you upload using facial recognition technology. It will then try to tie the face to a specific user. Oh, great, you say, that'll save me some time. Oh yeah, do you really want to be part of a gigantic biometric database?
So what can you do if you actually value that quaint old concept known as "privacy?" Stay tuned tomorrow for tips on protecting your personal information.
