Fingerprint fuzzy vault using hadamard transformation

Biometric system is a security model which could not be easily cracked or penetrated as compared to the traditional methods like password, ID card to get information. Trait information storage of a particular person in the database makes it vulnerable to template database attack. Fuzzy vault is a popular biometric cryptosystem technique that provides security to the biometric templates. The challenge faced by fuzzy vault is it sans the potential of cancellability and diversity which restricts its implementation in real applications. With great efforts of researchers, some approaches are designed to provide cancellability and diversity in the fuzzy vault. This paper provides insight about such approaches and a proposed technique which verge to satisfy issues regarding template protection scheme. Proposed technique is applied on the fingerprint trait.
