Nearly 250 million video surveillance cameras have been installed throughout the world, and chances are you've been seen by several of them today. Most people barely notice their presence anymore — on the streets, inside stores, and even within our homes. We accept the fact that we are constantly being recorded because we expect this to have virtually no impact on our lives. But this balance may soon be upended by advancements in facial recognition technology. 

Soon anybody with a high-resolution camera and the right software will be able to determine your identity. That's because several technologies are converging to make this accessible. Recognition algorithms have become far more accurate, the devices we carry can process huge amounts of data, and there's massive databases of faces now available on social media that are tied to our real names. As facial recognition enters the mainstream, it will have serious implications for your privacy.

A new app called FindFace, recently released in Russia, gives us a glimpse into what this future might look like. Made by two 20-something entrepreneurs, FindFace allows anybody to snap a photo of a passerby and discover their real name — already with 70% reliability.
