An experimental algorithm out of Facebook's artificial intelligence lab can recognise people in photographs even when it can't see their faces. Instead it looks for other unique characteristics like your hairdo, clothing, body shape and pose.
Modern face-recognition algorithms are so good they've already found their way into social networks, shops and even churches. Yann LeCun, head of artificial intelligence at Facebook, wanted to see they could be adapted to recognise people in situations where someone's face isn't clear, something humans can already do quite well.

The final algorithm was able to recognise individual people's identities with 83 per cent accuracy.
"If, even when you hide your face, you can be successfully linked to your identify, that will certainly concern people," says Ralph Gross at Carnegie Mellon University in Pittsburgh, Pennsylvania, who says the algorithm is impressive. "Now is a time when it's important to discuss these questions."
Another reason not to be on FB. Or out in public.
