They tested it against lifelike face masks, I doubt that would work, fortunately. They mentioned an IR camera, wouldn't be surprised if they're checking temperature as well.
- randyrand 9y agoPeople misunderstood what the static face masks were for. The static face masks were not for testing against a face-mask attack. They were for testing FaceID. As far as testing goes, the mask was assumed to be a stand-in for the real person.

- randyrand 9y ago2 years of work experience with Primesense 3d cameras. I'm well aware of what they are capable of. That said, they could use the color video feed to require subtle eye movements which would make this attack harder.
- wiremine 9y agoYeah, that's doesn't seem to jive with how they described it on stage...
- randyrand 9y agoI re watched the video, and you're right. They said they used the masks to help prevent against mask attacks. To the extent that it worked, we don't know. Since I am very familiar with the tech, I know that IR light does not have any special properties in detecting a mask vs human skin. But I assume the nueral network they trained looks for movement of some sort.

Since you're familiar with the tech, you'll be aware that humans, who are alive, emit IR light which can be picked up by an IR camera, and a mask, which is not, does not.
- detaro 9y ago"IR" as in the heat coming of a human body is very different from "IR light" that is used in setups like this. Just like a cheap phone camera might be able to see the IR from a TV remote, but can't see body heat. And even if it could, heating a mask to body temperature isn't all that difficult.
- MBCook 9y agoWe don't know that yet. We'll find out more when they release the white paper and people get their hands on them.
