Here are some general ideas for "encrypting" one's image: Ear muffs, long hair, etc. (Tim May mentioned ears are good for recognition) Makeup variety Beard variety (mustache, full beard, beatnik, sideburns, etc.) False scars, moles, etc. Variety of hats & eyeglasses Realistic looking masks (available from film or theatre prop/makeup companies?) Gloves (if they start looking at hands, unique jewelry, etc.) Scarves Anything too obvious (ski mask, sunglasses at night, the masks used for the "Wired" cover, etc.) might trigger smart algorithms to red-flag the image. As usual these techniques are popularly reputed to be the special province of criminals. Only a criminal would want to avoid giving the world a dossier on where they shop, travel, withdraw money, etc. right? Alas, that may be right: I suspect only smart criminals and secret agents will go to the expense of doing this stuff; innocent trusting citizens will be the ones building their dossiers for the Security of the State.
