The Pandora's Box Facebook opened on the privacy issue just keeps spewing forth. This time around they've started changing privacy settings to automatically recognize a user's face in an image ready to be tagged. All without their consent.
The feature is called Tag Suggestions, and Facebook started rolling out the service late last year. It essentially maps your face and detects whether or not it matches us with images amongst your friends' albums. It then nudges them into tagging those pictures accordingly. This would be great for the average beach trip where tagging the same people over and over would be a bother, but it becomes problematic when a well-meaning friend or mistress tags you in something incriminating.
