This week at the Black Hat security conference researchers from Carnegie Mellon University demonstrated how facial recognition technology can be used to positively identify a person and possibly even to gain access to their personal information.
The Carnegie team used three relatively simple technologies to create their face recognition system: An off-the-shelf face recognizer, cloud computing processing, and personal data available through the public feed at social networking sites such as Facebook.
They were even able to reproduce some of the effects using a smartphone app that overlayed parts of their deduced ID data onto a view of the world in real time using an augmented reality app.
