Biometrics deals with the problem of identifying individuals based on physiological or behavioral characteristics. Since many physical characteristics, such as face, iris, etc., and behavioral characteristics, such as voice, expression, etc., are unique to an individual, biometric analysis offers a reliable and natural so- lution to the problem of identity verification. In this chapter, we discuss image and video-based biometrics involving face, iris and gait. In particular, we discuss sev- eral recent approaches to physiological biometrics based on Sparse Representations and Compressed Sensing. Some of the most compelling challenges and issues that confront research in biometrics are also addressed.
