Forget “facial” recognition. Facebook is getting so good at identifying you in photos that it doesn’t even need to see your mug.

According to New Scientist, the social network has developed an “experimental” algorithm that can identify you in photos without seeing your face. Instead, it uses other characteristics—like your hair, clothing, body shape, and how you carry yourself—to figure out it’s you.

To test the new algorithm, the Facebook team pulled nearly 40,000 public photos from Flickr offering a variety of face shots and snaps where people were looking away. The team then ran these photos through its “sophisticated neural network” and the algorithm was able to identify people with 83 percent accuracy, according to the report.

New Scientist notes that Facebook may in the future integrate this new technology into its photo-sharing app Moments, which has drawn criticism from privacy advocates over its use of facial-recognition technology. The app, launched last week in the U.S., groups images on your phone based on when they were taken and, using facial-recognition software, which friends are in them.
