The 1st point is, everything went much more easily than you expect. You can try it out with your own iPhone X, the phone shall recognize you even when you cover a half of your face. It means the recognition mechanism is not as strict as you think, Apple seems to rely too much on Face ID's AI. We just need a half face to create the mask. It was even simpler than we ourselves had thought. Interesting. I expected this to be some quite obscure technique.

> We used a popular 3D printer. Nose was made by a handmade artist. We use 2D printing for other parts (similar to how we tricked Face Recognition 9 years ago). The skin was also hand-made to trick Apple's AI. That seems reasonably obscure (:

  This is the first step, it's only going to get easier from now on.

    Sure, but Face ID will also evolve.

There was also a rumor that Apple was having trouble with FaceID recognizing people (it even happened to Craig Federighi on stage!), and they made the security less strict so it recognizes people more easily. For all we know, FaceID doens't have that "1 in a million" False Acceptance Rate" anymore, but only 100,000 which would be a lot closer to a fingerprint.

  What happened to Craig was that he tried to unlock a freshly rebooted phone. iOS requires the user’s passcode after booting, and won’t allow a biometric unlock until after that.

    No, it was actually the people setting up the stage accidentally triggered Face ID often enough that it fell back to passcode. Could find a link to Apple's explanation if needed.

      Thanks, you're right. It looks like it was initially reported as having been rebooted like I said, but Apple later on explained it as you say, and I must have missed the update. Here's a link: https://9to5mac.com/2017/09/13/face-id-demo-fail-details/ https://9to5mac.com/2017/09/13/face-id-demo-fail-details/ Anyway, the key point here is that Face ID didn't fail to recognize Craig, it refused to recognize him because it had already been locked.
