There is no privacy

This is the common public version of the talk I've attended by Vitaley Shmitakov. The scientific paper will be publish within a two months. it's really really important to realize the fact that any piece of information, even if not personally identifying, can reveal your identity. Even just the number of your friends on facebook can do that ! (btw, my research in masters is about privacy in social networks).

For example, University of Texas professor Viatly Shmatikov and Stanford University researcher Arvind Narayanan were able to identify more than 30 percent of users of both Twitter and Flickr, even thought the accounts had been stripped of identifying information like account names and email addresses. At Carnegie Mellon University, researchers Alessandro Acquisti and Ralph Gross reported they could accurately predict the Social Security numbers for 8.5 percent of the people born in the United States between 1989 and 2003--nearly 5 million people
