By next year, Moscow's subway will be scanning your face from the moment you walk in

In an interview with the newspaper Izvestia, the head of the Moscow subway system, Dmitry Pegov, revealed that the city is planning to activate a “smart surveillance system” before the end of the year that will scan the faces of passengers. The new system, Pegov says, will help identify potentially dangerous persons and objects.

Special cameras are already being installed at the entrances and platforms of all Moscow metro stations. (There will be 20,000 new cameras, all together.) The new system will scan individuals as soon as they enter a subway station, and be capable of tracking that person's movements within the metro. 

According to Pegov, surveillance workers will have access to a police database, and anyone behaving suspiciously on camera will be identified using those records.
