Biometrics is a rapidly evolving field with applications ranging from accessing one's computer to gaining entry into a country. The deployment of large-scale biometric systems in both commercial and government applications has served to increase the public's awareness of this technology. Rapid growth highlights the challenges associated with designing and deploying biometric systems. Indeed, the problem of biometric authentication is a "Grand Challenge" in its own right. Recent years have seen significant growth in biometric research resulting in the development of innovative sensors, new algorithms, enhanced test methodologies and novel applications. This book addresses this void by inviting some of the prominent researchers in Biometrics to contribute chapters describing the fundamentals as well as the latest innovations in their respective areas of expertise. Designed for researchers and advanced-level students in computer science, the Handbook of Biometrics is also suitable forBiometric and Computer Security professionals.
