It may be time to start treating the entire web as one interconnected data collection form. Innocuous information you share online can be used to deduce your movie rental habits, political affiliation, and even your social security number.

Consider this:

•    Netflix inadvertently revealed the identities of some of their subscribers even though they removed personally identifying information from their publically available database. Two University of Texas researchers were able to match Netflix subscribers’ to their reviews of vulnerable movies on sites like IMDB.

•    Another discovery out of the University of Texas, this time involving an assistant professor and his student, was that peoples’ political affiliations can be inferred from social networks. Group membership, music preference, and friendship connections were particularly indicative of political affiliation. The dataset for this experiment was 167,000 online profiles and 3 million ‘friends’ in the Dallas-Fort Worth area.

•    Even those who are unconcerned that others can see their movie rental records, or know their political persuasion, would be upset if their social security numbers were uncovered. Another duo of researchers, in this case from Carnegie Mellon University, were able to destabilize the Social Security numbers of 8.5% of US citizens born from 1989 to 2003 based on publically available data including social network profiles.

As Maneesha Mithal of the Federal Trade Commission’s privacy division stated in The New York Times, “Technology has rendered the conventional definition of personally identifiable information obsolete…You can find out who an individual is without it.”

So do we need to protect the next generation of Internet contributors, those born since 1995 referred to as Gen Z? In The New World of Wireless: How to Compete in the 4G Revolution Scott Snyder writes that Gen Z are the most likely generation to accept reduced privacy in order to participate in the “immersive, ‘user-centric’ wireless experiences” delivered by 4G mobiles. Encouragingly, this generation is demonstrating an ability to engage and minimize their public exposure. Regulatory body Ofcom’s media literacy audit found that a full quarter of 8-12 year old UK citizens have social networking profiles on Facebook, MySpace, or Bebo. A vast majority of this active quarter, 83%, have set their privacy settings to only allow their friends to see their profiles.

I think Gen Z will be just fine; we don’t need to instill a mistrust of academics that travel in twos or teach them about the interrelated nature of the Internet. Let’s concentrate on ourselves and realize that by placing our first name on one site and our last name on another site we’re effectively placing our full name in the same place.
