But then they'd have to come up with some kind of make sure the person is really not just a photograph detector. Hmm... Maybe it asks you to blink your eyes in some pattern?

Biometric systems for regular computers are pretty useless. They'll deter casual attempts at getting in and nothing more. I guess if you're using it for the situation you describe then it'll be good enough security.

Your blinking idea would be circumvented by cutting eye holes in the photo.
