A Survey on Biometric Template Protection Using Hybrid Approaches

Biometric authentication due to its merits compared to traditional authentication methods like password finds its application in several crucial applications like border security, military, network security and forensic applications. However, biometric authentication systems are subjected to several attacks. Providing security to biometric template is an important issue in any biometric authentication system. Different biometric template protection mechanisms are in practice. Anyhow, no single method provides all the required properties of a biometric template. Hybrid template protection mechanisms are better compared to single biometric template protection mechanism. This paper presents a survey of different works that provides hybrid biometric template security.
