stefan brandtIn social networks, people can increase their defenses against identification by adopting tight privacy controls on information in personal profiles. Yet an individual's actions, researchers say, are rarely enough to protect privacy in the interconnected world of the Internet. The FTC is worried that rules to protect privacy have not kept up with technology. The FTC and Congress are weighing steps like tighter industry requirements and the creation of a "do not track" list, similar to the federal "do not call" list, to stop online monitoring.

In a class project at the Massachusetts Institute of Technology that received some attention last year, Carter Jernigan and Behram Mistree analyzed more than 4,000 Facebook profiles of students, including links to friends who said they were gay. The pair was able to predict, with 78 percent accuracy, whether a profile belonged to a gay male.
So far, this type of powerful data mining, which relies on sophisticated statistical correlations, is mostly in the realm of university researchers, not identity thieves and marketers.

You may not disclose personal information, but your online friends and colleagues may do it for you, referring to your school or employer, gender, location and interests. Patterns of social communication, researchers say, are revealing.
“Personal privacy is no longer an individual thing,” said Harold Abelson, the computer science professor at M.I.T. “In today’s online world, what your mother told you is true, only more so: people really can judge you by your friends.”

Collected together, the pool of information about each individual can form a distinctive “social signature,” researchers say.

Even more unnerving to privacy advocates is the work of two researchers from Carnegie Mellon University. In a paper published last year, Alessandro Acquisti and Ralph Gross reported that they could accurately predict the full, nine-digit Social Security numbers for 8.5 percent of the people born in the United States between 1989 and 2003 — nearly five million individuals.

More generally, privacy advocates worry that the new frontiers of data collection, brokering and mining, are largely unregulated. They fear “online redlining,” where products and services are offered to some consumers and not others based on statistical inferences and predictions about individuals and their behavior.

But Jon Kleinberg, a professor of computer science at Cornell University who studies social networks, is skeptical that rules will have much impact. His advice: “When you’re doing stuff online, you should behave as if you’re doing it in public — because increasingly, it is.”

That helped them figure out the first three digits of each Social Security number, which the government had assigned by location. The remaining six digits had been assigned through methods the government didn’t disclose, although they were related to when the person applied for the number. The researchers used projections about those applications as well as other public data, like the Social Security numbers of dead people, and then ran repeated cycles of statistical correlation and inference to partly re-engineer the government’s number-assignment system.
To be sure, the work by Mr. Acquisti and Mr. Gross suggests a potential, not actual, risk. But unpublished research by them explores how criminals could use similar techniques for large-scale identity-theft schemes.
