Facebook is using facial detection software to prove users are actually human. As artificial intelligence becomes more prevalent and social media spam bots continue to be a nuisance, more sophisticated computing tests may be required. Captcha challenges are commonplace, but lately Facebook has been using facial detection 'Face Captchas' to be more certain robots aren't trying to sign up to the social network.
Facebook users have been asked to verify their identity by uploading photos of themselves. The security message reads "Please upload a photo of yourself that clearly shows your face. We’ll check it and then permanently delete it from our servers." Redditors noticed this development as early as last April, while the practice is becoming increasingly well known through sharing on Twitter.
