Yes, though it would be equivalent to a label or sticker on an item in a store (note: not a barcode). It wouldn't carry meaning from a technological perspective (though I guess Facebook could try to mine that). The problem with Facebook's facial recognition features is that it has to recognize all faces, even faces that don't want to be recognized, to know which faces to legally not recognize. It's an all-or-nothing feature across its entire user base. It can't even be geofenced because users travel and upload from all sorts of parts of the world and wind up in the background of several photos. Facial recognition is a "logical feature" in that it mimics how people recognize people, but is problematic when applied at scale.
