Published online by Cambridge University Press: 11 September 2009
Summary
Biological features have been investigated extensively by many researchers and practitioners in order to identify the users of information, computer, and communications systems. There are an increasing number of biometric-based identification systems that are being developed and deployed for both civilian and forensic applications. Biometric technology is now a multi-billion dollar industry and there is extensive Federal, industrial, business and academic research funding for this vital technology especially after September 2001.
An automated biometric system uses biological, physiological or behavioral characteristics to automatically authenticate the identity of an individual based on a previous enrollment event. In this context, human identity authentication is the focus. However, generally this should not necessarily be the case.
This chapter aims at reviewing state-of-the-art techniques, methodologies, and applications of biometrics to secure access to e-based systems and computer networks. It will also shed some light on its effectiveness and accuracy of identification as well as trends, concerns, and challenges.
Introduction
Biometrics deals with the process of identifying persons based on their biological or behavioral characteristics. This area has received recently a great deal of attention due to its ability to give each person unique and accurate characteristics. Moreover, the cost of implementing such technology to identify people has decreased tremendously. Biometrics techniques have been widely accepted by the public due to their strengths and robustness (Obaidat, 1997; Obaidat, 1999).
Identifying the identity of an individual involves solving two major issues: (a) verification, and (b) recognition.
