A new camera technology from Hitachi Hokusai Electric can scan days of camera footage instantly, and find any face which has EVER walked past it.
Its makers boast that it can scan 36 million faces per second.
The technology raises the spectre of governments - or other organisations - being able to 'find' anyone instantly simply using a passport photo or a Facebook profile.
