A face in a billion: Facebook to include profile pix in facial recognition database...

Facebook says it will expand its facial recognition database to include over 1 billion extra faces as it incorporates users’ profile pictures into its database, thereby increasing the scope of its existing, highly controversial technology.

The world’s largest social network made the announcement Thursday in an update to its data use policy. Facebook’s “Tag Suggest” feature already automatically recognizes “friend” faces in photo uploads to speed up the process of tagging friends, but the new adaptation will also use the facial recognition technology to identify its own users’ profile pictures.

“Our goal is to facilitate tagging so that people know when there are photos of them on our service,” Erin Egan, Facebook’s chief privacy officer, told Reuters, adding that the change would give users better control over their information.

 Facebook’s existing technology identifies faces automatically by comparing them to previous tagged photographs. Full story...
