Hand Shape Based Biometric System:A Survey

Modern security systems used in various sectors are emerged to use a person's biological characteristics such as fingerprint, eye, hand, palm etc which is referred to as biometrics. Automated biometric systems are most robust so act as a better option to the traditional systems. It widely used as a method for identification and verification based on physical or behavioural characteristics. Among various biometric characteristics, Hand geometry is one of the most well-known biometrics. Because of its ease of collectability, low resolution imaging, Public acceptance, low cost and low template size so have gained popularity in low to medium security systems. A survey has been presented in this paper describing various hand shape-based biometric system Technologies. Component modules used in commercial systems along with recent successful deployments will be reviewed. Finally, analyze the practical issues concerning performance and limitations and put light towards future research related to hand shape biometric systems.
