>So the model is verifying faces against ... A database of zero faces? Surely there's 200M faces in there, or else how does it work?
No. The model is, "Hey! this guy is being a pain in the ass. He even claimed that The President wasn't blessed with superintelligence and doesn't actually smell really good!
We need to get this terrorist off the streets! He sure looks a whole lot like that illegal on the FBI most wanted list, doesn't he? Off to CECOT with him!
What's that? He's a twelfth generation citizen? No way! Look, the app I used to claim this guy matches an illegal who's also a child rapist!
Your papers are all fake (if, as a citizen he's even carrying them). Onto the plane with you Senor.
That's the model. Feel free to disagree, but come back and reread this comment in 18 months. I hope you read it then and think "what a paranoid guy! Nothing like that could ever happen here!" But I'm not holding my breath. :(
