I was thinking about face ID the other day. What if you trained it while making a funny face? So then you would have to make that face to unlock the phone and how could someone compel you to do so? It's sort of a 2-factor authentication in a way.
That's a fair point. Not sure if that's been litigated yet.
The only reason that a cop can't compel you to give up a pin or a passcode is because that is information you have in your brain, and they can only compel actions, not information.
They could probably compel you to make a face, but they couldn't compel you to unlock the phone with your face without knowing what that specific face is, and they can't make you provide them with the information on that specific face either.
Right, so your choice of facial expression would, in effect, act like a passcode. Good luck breaking into Jim Carrey's phone!
I got the idea initially when I noticed I couldn't unlock the phone while laughing. Then I got annoyed and I guess angry face didn't work either.
I wonder now what would be the minimum facial contortion you would need to make a distinct ID? It could be something as subtle as curling your lip or raising a cheek muscle slightly? I might have to experiment with this a bit…
