Chinese boffins use infrared LEDs to fool security cameras

Fool facial recognition software

A group of Chinese computer boffins has published a paper claiming that you can mess up 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 categoriser should "see" and apparently the researchers could convince the cameras that they were looking at the musician Moby or the Korean politician Hoi-Chang. Quite what the researchers had against Moby is unknown, we guess they didn't like his last album.

Their experiment is based on finding blind spots in machine learning models that can be systematically discovered and exploited to confuse these classifiers.

The gadget used in their attack is not readily distinguishable from a regular ball-cap, and the attack only needs a single photo of the person to be impersonated to set up the correct light patterns.

In this paper, the researchers discovered that infrared could be used by attackers to either dodge or impersonate someone against machine learning systems.
