According to this article by Farhad Manjoo at Slate Magazine, Google has software that can identify your face most of the time if there are as few as 17 photos of you online. If there are 50, they can identify almost every time.
And all the other software giants have this same capability. They’re just waiting for the tipping point on public acceptance.
Manjoo believes that time is almost here: the technology has gotten so good, cameras are ubiquitous, and Facebook has diminished our sense of privacy.
The police officer that stops you won’t need your driver’s license anymore. He or she will just take your photo and the computer will tell them everything there is to know about you.
Oh, and if you ever look up at the sky, be sure to smile. You’re on candid camera.
