Improved techniques employ all sorts of fuzzy and statistical measures to produce "templates" that can be reliably matched, despite *some* variations in a read. My issue with biometrics is that, in the zealous desire to find more definitive forms of attribution, it is often considered the "final word". I have wondered, if biometrics were to become commonplace, whether it will become a criminal offense to publish your biometric data in public fora. "Here are the holographic images of my fingerprints, my retinal scans, and my skin conductivity measurements. Go ahead and use them to impersonate me if you like." Would this help to enable a repudiation defense? "It wasn't me. Anyone could have placed my prints there." The problem with biometrics is that they cannot be "revoked" if compromised. If someone steals my fingerprints, I cannot (yet!) get a new set of fingers. ___tony___ Tony Bartoletti 925-422-3881 <azb@llnl.gov> Information Operations, Warfare and Assurance Center Lawrence Livermore National Laboratory Livermore, CA 94551-9900 ------------------ http://all.net/ Your use of Yahoo!
