Abstract & Overview
Biometric systems are used to authenticate the identity by measuring the physiological and/or behavioral characteristics.So, the two main categories of biometrics are 'physiological' and/or 'behavioral'.The physiological category includes the physical human traits such as palm print, hand shape, eyes, veins, etc.The behavioral category includes the movement of the human, such as hand gesture, speaking style, signature etc.The measurement of these traits helps in authentication using the biometric systems.The palm print based systems for verification make use of ink marking to capture the palm print patterns.These systems are not widely accepted because of high attention and co-operation of users to provide data.Recently digital camera is used to capture images and users hand placing is constrained using pegs.
