Your Skin Is Your Password

The light reflects through a person's skin and is uniquely reflected back to a receiver. The researchers believe that this has some major applications including improving hand gun saftey locks and preventing cellular phone theft."

    Well, let's go read the article:

    "Unlike biometrics like fingerprinting and face recognition (see "Face Recognition", TR Nov 2001), light printing doesn't rely on image-processing. Instead, the device measures wavelengths of reflected light, which requires considerably less computing power."

    So, its a fairly different method, meaning different solutions to it application.

    "Norton says, "but the point is that fingerprint technology cannot determine 'liveness.' You can't foil the Lumidigm system with fake or dead tissue.""

    So, maybe it's more reliable?

    Either way tho, I agree with the guy down there who disbelieves it -- if you're measuring the wavelength of reflected light, couldn't that change drastically (enough to make it useless) over time?
