ABSTRACT
Biometric devices have been suggested for use in applications from access to personal computers, automated
teller machines, credit card transactions, and electronic transactions to access control for airports, nuclear
facilities, and border control. Given this diverse array of potential applications, biometric devices have the
potential to provide additional security over traditional security means such as passwords, keys, signatures,
picture identification, etc. Examples of biometrics include recognition of a fingerprint, face, voice, iris, and
handprint [1,2]. The following are the basic components and function of a system, as shown in Figure 26.1.
