Hitachi Hokusai Electric is releasing, within the next year, a CCTV camera system that stores a biometric record of every face it photographs and can scan for that face at 36 million faces per second.
The system will enable large retail stores, the government, Railways or any business with a extensive surveillance system to identify all faces on it´s CCTV records.
Potentially the government could use a Facebook photo or any picture to "find" the individual.
