Biometric Systems have an edge over the traditional security methods as they strengthen the level of security by authenticating only the genuine person. Various security breaches and their remedial solutions for biometric systems are proposed by eminent researchers. Template security is one of the major concerns in the field of Biometric Security. Fuzzy vault is a proven template protection scheme. The basis of the scheme is to bind the biometric information with the secret key and scramble it by adding random data to add more security. However, the scheme is vulnerable to the correlation attack. A successful correlation attack may lead to the recovery of genuine minutiae points in the input fingerprint, which may lead to the recreation of the input finger. The main focus of the current research work is to design a secure Fuzzy Vault scheme to prevent correlation attack. The proposed scheme combines fuzzy vault and hadamard transformation technique, providing the indemnity against correlation attack to an appreciable level.
