Nearly 1 trillion photos, spread across 1.2 billion users worldwide. Since 2010, Facebook has been using those photos to fuel a powerful facial recognition engine. When you upload a photo of someone, Facebook will almost always know who that person is, encouraging you to tag them and let them know. Thanks to the mountains of data, it’s become one of the most advanced facial recognition systems available, far beyond the FBI’s face-scanning system. It’s also a crucial product for Facebook itself, integrated into the Messenger app earlier this year.
Now, a new lawsuit has called that system into question, claiming Facebook’s biometric faceprints violate user privacy. See http://goo.gl/X269L6.
