<p>Biometrics is the science of recognizing a person on the basis of physical or behavioral characteristics. Things you can carry, such as keys or ID badges, can of course be lost, stolen, or duplicated. The same goes for things that you know, such as passwords or personal ID numbers. Biometrics relies on who you are--on one of any number of unique characteristics that you can't lose or forget.</p>
