ABSTRACT
All these systems have one thing in common: they all use biometrics to provide for enhanced security of
people, locations, or financial interests. Biometrics is becoming one of the fastest growing segments of the
security field and has gained a great deal of popularity both in the popular press and within the security
profession. The use of biometrics-how it works, how it is used, and how effective it can be-is the
subject of this chapter.
