According to Bloomberg, Moscow is adding facial recognition to 17,000 security cameras with the intention of IDing criminals on the streets.

The Russian city will use a facial-recognition technology developed by Ntechlab, which can look up faces users upload with photos posted on VKontakte, Russia’s “biggest” social network.

Authorities believe it will take faces it finds from surveillance footage and compare them only against photos already in police databases.

The police found 6 suspects based on its results during a two-month test run.

Russian IT expert, Mikhail Zyuzin, said to Bloomberg: “If the system is hacked by third parties, they could potentially get access to information on where you live, where you go and what routes you take.”
