- emilxix 6y agoSeveral layers of anti-spoofing. They detect mask-attacks, replay attacks (put the phone with video into the camera; highjack a webcam input and send a pre-recorded video faking to be real-time from zoom for example), and, of course, still images. Give it a try!
- pmiller2 6y agoWouldn’t you still be vulnerable to attack via a 3D printed or resin cast face (possibly suitably painted)?
