From simply logging into your laptop to cross national borders, biometrics is being called upon to meet the growing challenges of identity management. With contributions from academia and industry by leading international authorities in the field, this unique book presents a comprehensive treatment of biometrics and offers full coverage of all topics in the field, including data acquisition, pattern matching algorithms, and issues that impact on the system level, such as standard , security, networks, and databases. It has been organized in three parts: sensors, advances in biometric matching algorithms, and topics related to issues at the system level. Main features: ? Including the advancement of new algorithms, including physiological biometrics (face from video, iris at a distance) and behavioral (handwriting, voice) and flashy new modalities in biometrics headprint ? Combining chapters devoted to touchless image capture, ultrasonic imaging and swipe methods Written for researchers and advanced students, this concise book that is needed is an ideal tool for use as a ready reference and capture the very latest in state-the-art research, providing readers with a broader understanding and deeper into the topic.
