I wonder whether this will generate a market for finger gloves etched with custom fingerprints. You'd want one for your spouse, so they can use your phone without needing you to finger it, for example. Probably it would come in a kit that you could use to custom-etch your finger glove. But if you lose it (the glove), I guess you are in trouble. Someone will find it, upload the pattern to Facebook, and your fingerprint is now in the public domain for the rest of time. Unlike a password, it's irrevocable. Unless you could "edit" your fingerprint with some customized secret pattern, etch that pattern to a finger glove, and then only that glove will unlock the device, not even your plain fingerprint. Or would some kind of capacitance sensor on the phone prevent the use of gloves or other spoofs?
