Biometrics is an application of technology to authenticate users’ identities through the measurement of physiological or behavioral patterns. The verification system offers greater security to the use of passwords or smart cards. Biometric characteristics cannot be lost or forgotten. As biometric characteristics are concerned with the very makeup of who we are, there are also security, privacy, and ethical concerns in their adoption. Fingerprint, iris, voice, hand geometry, face, and signature are all considered biometric characteristics and used in the authentication process. Examples of everyday biometric applications include thumbprint locks on laptop computers, fingerprint scanners to enter a locked door on a house, and facial recognition scans for forensic use. While there are several examples of biometrics currently in use, it is still an emerging technology. The purpose of this chapter is to provide a descriptive discussion of the current and future state of biometrics.
