Ah, face recognition, that nifty little feature that’s already making the still new fingerprint scanners (kind of) obsolete. Let’s face it, any technology that lets us skip a step is a welcome move. But, since these features often collect and use massive amounts of very personal information, there will always be that nagging question on just how is it being used.

That question was what dragged Facebook to the court in April this year after it was discovered the digital behemoth was using facial data without user consent. Apparently, Facebook had resorted to using “face templates” in its tag suggestions without letting anyone know.
