Fingerprints Template Security Using Daes with Secure Fuzzy Vault

Biometric systems are advanced technology, but this has also some security issues. Modules can be attacked by the attacker. Attackers mostly attacks on templates and databases which are critical parts of biometric systems because templates are stored record of an individual�s features. To prevent the templates from intruders encrypt the templates. In recent years, most of the security techniques have been developed. In this paper, proposes a multilevel encryption layer to secure the templates. We have work on fingerprints templates. Firstly we encrypt the templates with double AES but it work as single layer and to provide more security again encrypt the double AES layer with Fuzzy vault. Fuzzy vault is Key binding biometric cryptosystem. Experimental results show that the proposed method performs well in improving security of templates and security method does not reduce the matching accuracy.
