Last year, a Russian firm launched the website FindFace, which matches submitted photos to profiles on the social networking site VK, a regional Facebook imitator. If a stranger photographs you in the street or spots your image on another site, and you’re on VK, then FindFace can likely identify you by name. Trolls immediately began using the site to out actresses in adult videos, harassing them and their friends and shaming them on discussion boards with epithets like “burnt whore.”
Meanwhile, Moscow police use facial recognition on a network of 160,000 security cameras across the city, and China is using cameras with facial recognition to tag jaywalkers. You can also use your face to pay at some KFCs in China, and it’s required before toilet paper can be dispensed at some public restrooms. In Dubai, police wear Google Glass devices that identify the faces of people in front of them.
