Time to start 3D-printing faces...

[Someone1234]

You could, but it is an IR camera, so you better have the IR characteristics of your 3D face match also. If you combine IR and visible light photography you actually get a layered face-scan which is VERY hard to fake (not impossible, hard).

What if you just hack the webcam firmware - like celebrity hackers and FBI have done for years already?

[MichaelGG]

If you can modify firmware, you've probably already won. Unless the auth is done remotely and requires remote attestation, perhaps.

I'm sure it could be done with paper folding.

Come to think of it... print a cylindrical projection of the photo and then wrap around a cylinder...

And then point a projector at it to warm up the paper at the right places.

I really wish biometrics would quit claiming to be significant improvements over anything but writing your password on a post-it on the computer. They all fall very quickly.
