A Northern District judge in California has approved Facebook's $650 million class-action settlement for the lawsuit regarding its photo-scanning feature. The lawsuit claimed that Facebook’s Tag Suggestions tool, which scanned faces in users’ photos and offered suggestions about who the person might be, stored biometric data without users’ consent in violation of a Illinois law. The payment, which will be distributed among roughly 1.6 million plaintiffs, is one of the largest of its kind and a good reminder that what you post becomes fair game for Facebook to use at their discretion.
