Secure and Revocable Multibiometric Templates Using Fuzzy Vault for Fingerprint and Iris

Abstract

Biometric systems are subjected to a variety of attacks. Stored biometric template attack is very severe compared to all other attacks. Providing security to biometric templates is an important issue in building a reliable personal identification system. Multi biometric systems are more resistive towards spoof attacks compared to unibiometric counterpart. This work provides security and revocability to iris and fingerprint templates using password hardened multimodal biometric fuzzy vault. Password hardening provides security and revocability to biometric templates. Security of the vault is measured in terms of min-entropy. © Springer-Verlag Berlin Heidelberg 2010.
