Light trips up potential mobile hackers

Thursday, July 19, 2018

Researchers at Chinese University say they have invented a new security system which will prevent hackers from using masks or images to cheat facial recognition technology.

It involves shining a colored light onto a person's face when logging onto a mobile device or computer system, and then analyzing the light that is reflected back.

The researchers from the university's Department of Information Engineering said hackers would not have time to trick the technology.

Assistant professor Zhang Kehuan told RTHK's Jimmy Choi that this will improve security of the face recognition technologies.
