5.1.1.2  Biometrics

Biometrics, as discussed in earlier domains, adds an additional layer of security. Passwords coupled with biometrics involve authentication with something you are. Biometrics should not be used as the single means for authentication. Tsutomu Matsumoto of Yokohama National University has demonstrated two different techniques for circumventing biometrics with an 80 percent accuracy rate414. Biometrics such as a fingerprint scan can be included in a smartcard415.

While other biometric options are possible, such as facial or iris scanning, fingerprint scanning is currently the most popular biometric because it is the lowest cost option with the highest accuracy rate.
