The ‘Privacy Visor’ is a new piece of tech, which is ideal for people who don’t want to be identified by security cameras. It prevents computers from extracting the information needed to recognize a face.
Earlier this month PSFK wrote about hoodies that hide their wearers from thermal imaging. These technologies are great for those concerned with privacy but if the tech falls into the wrong hands, could it be more detrimental than beneficial?
The goggles, developed by Isao Echizen from the National Institute of Informatics and Seiichi Gohshi from Kogakuin University in Japan, emit near-infrared light from 11 LEDs. These disrupt the facial-recognition software of hidden cameras without affecting the wearer’s vision.
In an experiment using OpenCV face-detection software and ten volunteers, the detection rate when they wore the Privacy Visor was zero, regardless of how far away they were standing. Prof. Isao Echizen said:
As a result of developments in facial recognition technology in Google images, Facebook et cetera and the popularisation of portable terminals that append photos with photographic information [geotags]… essential measures for preventing the invasion of privacy caused by photographs taken in secret and unintentional capture in camera images is now required.
