Facebook’s artificial intelligence lab can recognize people in photographs even when their faces are hidden. This algorithm will recognize a person through their unique characteristics such as hairdo, clothing, body shape and pose.

The research team pulled almost 40,000 public photos from Flickr — some of people with their full face clearly visible, and others where the face was not visible and make them through a sophisticated neural network.

The  algorithm was able to recognize individual people’s identities with 83% accuracy, ‘New Scientist’ reported.

Advantage: A tool like this would be useful for people who are privacy-conscious as it could alert them whenever a photo of themselves, however obscured, pops up on the internet. However, the ability to identify someone even when they are not looking at the camera raises some serious privacy implications.
