Facebook files patent for using a photo’s camera signature to connect you with other users

9-18FBFacebook has filed a patent for a new way to ascertain the digital signatures of cameras from photographs and then associate it with users within a social network. The application notes that the association of camera with users can be used “beneficially for the social networking system” for things like recommending potential connections, events, or groups to users, detecting fraudulent accounts, and even determining affinity between users.
