When I was in China, I saw how many cameras there are everywhere. And how Chinese officials pass by high-speed trains with cameras.

For Chinese citizens, the state has trained facial recognition on millions of faces. They use it to detect people passing roads in red lights (they show names and faces in big screens)

But, I wonder what is the error rates for non-Chinese. Without enough samples I can be identified as any other person similar to me in skin color. Can I mistakenly be identified as some "person of interest" for the Chinese government? That was an scary though.

I see the usefulness of this technologies, but "pro-active" policing has high rates of false positives and many innocent people will be harassed or even worse just because a machine failure. All that without taking into account when the machines are right at persecuting opositors in dictatorial regimes.
