Facial recognition software could put social media users' identities at great risk, one researcher has discovered.
Alessandro Acquisti, an associate professor of information technology and public policy at Carnegie Mellon University, warned that social media users who post photos of themselves on the Internet are at great risk for identity theft, among other dangers.
In a series of experiments, Acquisti and his team applied off-the-shelf facial recognition tools to compare people who posted their photos on Facebook and dating Web sites. They were able to identify certain users and find information on them. Even scarier, they were able to identify people who operated on social media Web sites under different names.
Acquisti spoke about the findings at this year's Black Hat conference in Las Vegas. The results, he said, could be disastrous in terms of privacy concerns.

"Your face is the link between your offline identity and your online identity," he said.
