Abstract

Biometrics refers to the recognition of individuals based on their physiological and/or behavioral characteristics. The
biometric traits which may be considered for the authentication of a person are face, hand geometry, finger print, vein, iris,
etc. A competent selection of a sensor, its mechanism and adaptability is required, as the absence of these will leave the
biometric sensor deceptive to information sensing. Selecting a sensor for a biometric application from the large number of
available sensors with different technologies always brought the issue of performance and accuracy. Therefore, various error
rates and sensibility contention differentiate the available biometric sensors. This paper presents the difficulties faced in the
sensor module of the biometric system and the incomparable alternatives on the basis of availability of information at sensor
module of the various systems.
