24 Oct New Light Prevents Privacy Threat Posed By Smartphone Cameras
San Diego, USA – Researchers from the University of San Diego have developed a new kind of light which interferes with the ability of smartphone cameras to take pictures or record videos in artificially lit environments.
Called LiShield, the smart LED light generates distortion which causes modern phone cameras to simultaneously overexpose and underexpose, resulting to a barcode-like pattern that can even distort the color of the image or video.
The light, however, can still be used as a form of illumination since the distortion is imperceptible to humans. The technology is seen to bring positive implications to the privacy of individuals in locker rooms and similar spaces, as well as prevent unwanted recording of live performances.
