    It's apparent that this conversation could go on forever. It is also
    apparent that Ryan Thompson (original poster) is in search of a 100%
    fool proof method of authentication, which all of us know doesn't exist.
    Basically, we all seem to have come to the consensus that:

    1) Password security is not perfect due the inability of most
    people/users of data networks to remember and conjure up difficult,
    complex, or hard to guess passwords.

    2) Biometrics is not a fool proof method of authentication and there are
    ways to trick these devices.

    3) The generally agreed upon method for the most secure method of
    authentication over a seemingly insecure data network would be to
    combine a multitude of different technology, all dependent on each

    I don't doubt it (although I missed the special), but
    I don't know anyone who advocates the use of
    biometrics as the sole method of authentication (US
    airport security aside...). Most of the time I've
    used them you either needed a badge with it, or a
    badge/PIN combo. The addition of biometrics to a
    badge or badge/PIN combo -even if it was tuned to give
    more false positives than negatives- makes a huge

    So what interests me is could these guys beat the
    handprint reader WHILE they have a stolen/forged
    smartcard AND someone's PIN code (all matching the
    same person of course)? If they can do that then my
    hat is off to them and they should be Sneakers 2.

    Only fools have all the answers.
