With the introduction of facial recognition software on Facebook (also available on Flickr, Picasa, other photo-sharing sites, and photo-alteration programs), more people are becoming concerned about photo privacy. Facebook has a false sense of privacy (that only people on Facebook who are your friends can see the pictures), but that’s assuming no one is sharing the public link to the picture and that all your “friends” have air-tight privacy settings. In fact, Facebook saves a person’s tag even after the user deletes it. So what can you do to protect against associating your face and your name online (thus increasing the risk of identity theft)?
Obscure your eyes.
Most facial recognition technology fails when the eyes are covered, whether with sunglasses, goggles, or simply having your back turned.
So use your privacy as an excuse to go buy some cool sunglasses.
