This book fills a gap in the literature by detailing the recent advances and emerging theories, methods, and applications of biometric systems in a variety of infrastructures. Edited by a panel of experts, it provides comprehensive coverage of:

• Multilinear discriminant analysis for biometric signal recognition
• Biometric identity authentication techniques based on neural networks
• Multimodal biometrics and design of classifiers for biometric fusion
• Feature selection and facial aging modeling for face recognition
• Geometrical and statistical models for video-based face authentication
• Near-infrared and 3D face recognition
• Recognition based on fingerprints and 3D hand geometry
• Iris recognition and ECG-based biometrics
• Online signature-based authentication
• Identification based on gait
• Information theory approaches to biometrics
• Biologically inspired methods and biometric encryption
• Biometrics based on electroencephalography and event-related potentials

Biometrics: Theory, Methods, and Applications is an indispensable resource for researchers, security experts, policymakers, engineers, and graduate students.
