Nothing really new here (Score 1)

My previous company has been selling similar technology for more than two years (I should know, I wrote a big chunk of it). They get great numbers - including some of the best results - on every standard performance test.

All this technology really works only with "cooperative subjects", i.e. people who are willing to sit in fron of a stereo camera head and get a picture taken. Hence it is great for access control (secure areas, border check), can't be fooled by a picture it's a lot more convenient - though less accurate - than iris scan or fingerprints, and doesn't have the stigma attached to the latter in public opinion.

But recognize a face in a crowd? Forget about it. And forget about somebody who's ten years older or ten pounds fatter than the key stored in your database.
