From fingerprint readers to voice imprints, more and more businesses are using biometrics for many purposes -- but the question now is are consumers prepared to handle the privacy implications? If you have a driver’s license, a passport and a Facebook account, you are likely already documented in at least three different facial recognition databases. In defense of the data collectors, most biometrics are not secrets. A fingerprint or facial feature is unique to each individual, but they are not secret or able to be protected the way a password is. You can always change your password but biometrics are for the most part immutable. With that in mind, it is important to note the law doesn't recognize a right to privacy over anything that is revealed to the public. In this case, that includes just showing your face.
