Facial Recognition: What Happens When We’re Tracked Everywhere We Go?
A majority of us go around showing our faces all the time. We post selfies on the internet. Walking down the street, we are unwittingly photographed by surveillance cameras and by strangers we inadvertently photo-bomb. Until recently, we’ve had little reason to think deeply about the fact that each of our faces is as unique as a fingerprint or a Social Security number.
Behind the scenes, though, a quiet revolution has been afoot to unlock the secrets of our faceprints. It has been powered by an enormous influx of AI expertise into Silicon Valley in recent decades, much of it drawn out of the computer-science departments of elite universities. These experts have been put to work on a number of long-term projects, including language translation and self-driving cars, and one particularly intense area of research has been facial recognition.
