A Survey on Biometric Template Protection Using Fuzzy Vault Scheme

Security is an important component in any authentication system. Biometric authentication is gaining much importance in the current linked scenario. Anyhow, biometric based authentication systems are subjected to a variety of attacks. Stored biometric template attack is one of the severe attacks. Biometric template plays a vital role in biometric authentication. Therefore, ensuring security to biometric template is a demanding issue in the present times. Fuzzy vault is a crypto biometric frame work that provides security to biometric templates. This paper presents a survey on the different work done on fuzzy vault scheme to protect biometric templates.
