Rich:
Here's an interview referenced over on RB by HP enterprise security expert Regis Duret in which he points out some security issues with the use of biometrics:

From the article:

"A password can be guessed, a smart card can be stolen, and your biometric fingerprint image can be stolen as well, directly from your PC - and that's something people don't often realize. It's very difficult to get your finger, but think about it: when you log in to a PC using fingerprint authentication, you put your finger on a small device, and that device captures an image and sends it to the PC. So it's just a file that people can hack. If somebody can get that file they can log in to your PC anytime they like.

Q. So biometric spoofing is not necessarily difficult?

Not if you have access to somebody's PC. In biometrics, it's not your fingerprint that they reference, it's a mathematical model of your fingerprint. It's just a file that sits on your hard drive. So if somebody can get access to that file they can send it again - what we call a replay attack. And the fact that biometrics cannot be changed is then an issue. Because if somebody knows your password, I can ask you to change your password. But if somebody has your fingerprint file, I cannot ask you to change your fingerprint."
