Edward Snowden leaked new documents which shows that a UK spy agency GCHQ considered using Microsoft Kinect camera to conduct mass surveillance on unsuspected individuals. It was revealed that GCHQ ran a program called 'Optic Nerve' which would target 1.8 million Yahoo users and mass collect their webcam images.
According to the news report, Optic Nerve project started with a prototype in 2008 and started by using Yahoo webcam to collect images. It also contained information about GCHQ considered using Kinect for a similar form of surveillance. Though the concept never came into play, many documents indicated that Kinect camera can provide 'fairly normal webcam traffic' as a part of Optic Nerve Program.
