http://www.nytimes.com/2009/07/07/us/07numbers.html?hpThe nation’s Social Security numbering system has left millions of citizens vulnerable to privacy breaches, according to researchers at Carnegie Mellon University, who for the first time have used statistical techniques to predict Social Security numbers solely from an individual’s date and location of birth.

The findings, published Monday in The Proceedings of the National Academy of Sciences, are further evidence that privacy safeguards created in the era before powerful computers and ubiquitous networks are increasingly failing, setting up an “architecture of vulnerability” around personal digital information, the researchers said.
The researchers, Alessandro Acquisti, an associate professor of information technology and public policy, and Ralph Gross, a postdoctoral researcher, noted that there were a range of implications from the research, including that it was now possible to routinely reconstruct sensitive personal information from the type of online postings frequently found on social networking sites and other public sources.
