Ping!
Hey, would a PHOTOGRAPH unlock the iPhone?...............
I have the iPhone X and I believe a photograph is insufficient. The way Apple implemented FaceID — and I’m probably simplifying the actual process — is that it uses stereo cameras (one visible, one IR) with a projected IR dot grid to build a 3D mesh of your face from multiple angles.
The calculated values are hashed and stored in a protected area of the phone, accessible only through Apple’s interface.
A photograph would not return the correct depth map and would be rejected. It’s actually quite amazing what they pulled of. It’s accurate, fairly quick, and works in a wide variety of lighting conditions.
It can even work if you are wearing glasses (including sunglasses) or haven’t shaved in a while. Although I’ve found after about 10 days of going without a shave it can get a little confused sometimes.
As always, you can disable it and go to a complex passcode if you prefer.
I don’t know but I’m betting not. The article says they’ve designed in “liveliness” detection; i.e., Apple has tried to make certain facial recognition won’t work with a person’s dead face. They didn’t say exactly how they achieved that... whether by looking for color in the face or looking for small movements in the eyes or muscles of one’s face, etc.
Or a close up video. Would appear more real.
No, actually. The iPhone uses a “dot projection” 3D scanner to digitize your face. The face must actually have depth to unlock the phone. I guess a wax model might do...
