Facebook facial recognition: a threat to privacy?
By the end of this year, the world's population is expected to hit seven billion. That's a huge number, but it pales in comparison to the 60 billion to 100 billion photos Facebook has reportedly stored on its servers.
I bring this up, of course, because Facebook users are clicking their little fingers off tagging those billions of photos, and Facebook is happily adding those tags to its enormous databases of personal information.
