Facial Recognition in Use Carnegie Mellon University conducted experiments to see if an individual could be identified based on the availability of select information, both online and offline. They searched public profile images from online social networks and compared them to dating sites to determine how accurate the software was in identification They collected images of consenting students walking on a campus, and compared those to Facebook. Students provided some information and were asked to identify themselves in offline images. Researchers gathered personal information previously unknown from a face by training an algorithm to identify Facebook profile owners.
