Security is a very important aspect in the biometric systems. Biometric characteristics are unique to an individual hence the compromise of the biometric template is permanent. Attackers mostly attack on template and database of biometric system so securing them is a very crucial issue these days. Moreover the multi-biometric systems require storage of multiple biometric templates (e.g., fingerprint, iris, and face) for each user, which results in increased risk to user privacy and system security. In this paper, the authors' focus is on template security in biometrics system and they develop a system to encrypt and decrypt the biometric images. In this work, multi-modal biometric template security for palm print and fingerprint is proposed.
