Vulnerabilities have been uncovered in the authentication process of biometrics technology that could allow bad actors to bypass various facial recognition applications — including Apple’s FaceID. But there is a catch. Doing so requires the victim to be out cold. From a report: Researchers on Wednesday during Black Hat USA 2019 demonstrated an attack that allowed them to bypass a victim’s FaceID and log into their phone simply by putting a pair of modified glasses on their face. By merely placing tape carefully over the lenses of a pair glasses and placing them on the victim’s face the researchers demonstrated how they could bypass Apple’s FaceID in a specific scenario. The attack itself is difficult, given the bad actor would need to figure out how to put the glasses on an unconscious victim without waking them up.
To launch the attack, researchers with Tencent tapped into a feature behind biometrics called “liveness” detection, which is part of the biometric authentication process that sifts through “real” versus “fake” features on people. It works by detecting background noise, response distortion or focus blur. One such biometrics tool that utilizes liveness detection is FaceID, which is designed and utilized by Apple for the iPhone and iPad Pro. “With the leakage of biometric data and the enhancement of AI fraud ability, liveness detection has become the Achilles’ heel of biometric authentication security as it is to verify if the biometric being captured is an actual measurement from the authorized live person who is present at the time of capture,” researchers said during the Black Hat USA 2019 session.
