Isn’t it strange that a room-temperature face can unlock the phone when Apple has made it clear that the iPhone X uses the temperature of the face to detect masks etc.? From the perspective of the IR camera, the mask and that guy’s face should look completely different. This attack makes it look like it’s not using this information at all.
- rsl7 9y agowell.. if you have already advanced to the point where you're making a mask, I imagine it wouldn't be too hard to heat it up a bit.
- mathgaron 9y agoThe IR camera is near-infrared, it measures more or less light that your eyes can't see, and no heat frequencies. The IR camera is used to recover 3D information: https://en.wikipedia.org/wiki/Structured-light_3D_scanner https://en.wikipedia.org/wiki/Structured-light_3D_scanner
