Recognizing Your Own Handwriting As A Password 151
Gary writes "A new online authentication system called Dynahand could make logging in to websites a little easier. With Dynahand, users simply identify their own handwriting, instead of entering a cryptic password or buying a biometric device to scan their fingerprints. The user's handwriting samples contain only digits, since numerals are harder for an outside party to recognize than letters are. The digits displayed are random, so the handwriting is the only clue to the correct answer."

How about typical credential operations? (Score:3, Informative)
There is no improvement here over biometrics or other credentials falling into the “something you are” category. How do you revoke this credential? How do you limit its scope? I would even argue this is worse than a password because it is not easily changed, and worse, your signature is very public. Consider how many documents you have floating around with your hand-written signature on it. You really want to use something that can be learned and easily reproduced as a secret? Nonsense. We need real solutions (OpenID [wikipedia.org] is a start), not rehashes or regressions of old schemes.
