Russian facial recognition app sparks interest, controversy

A facial recognition app out of Russia is raising eyebrows, both because of its abilities and the privacy concerns it sparks. The app, FindFace, involves users submitting photos-- for example, of someone they saw on the street and might like to be able to contact. Then, the app searches a Russian social network called Vkontakte to look for a match with a reported accuracy of about 70 percent among the millions of accounts. It's even performed better than Google at a competition called MegaFace. While some have praised the app for its ability to make successful matches-- law enforcement and casinos are said to be interested in the tech-- others have privacy concerns.
