A group of Chinese computer scientists from academia and industry have published a paper [PDF] documenting a tool for fooling facial recognition software by shining hat-brim-mounted infrared LEDs on the user’s face, projecting CCTV-visible, human-eye-invisible shapes designed to fool the face recognition software.
The tactic lets the attacker specify which face the categorizer should “see” — the researchers were able to trick the software into recognizing arbitrary faces as belonging to the musician Moby, the Korean politician Hoi-Chang and others.
Universal biometric identification is a primary goal of governments. Facial ID is their holy grail because it has no language barriers, is easily collected and is presumably reliable. There’s still nothing out there that allows you to defeat this technology. The challenge is ongoing.
