摘要

Individual identification can be accurately done by measuring biological parameters termed as biometrics. These have been proved as an exceptional tool for identity verification. Security of biometric template is the most challenging aspect of biometric identification system. Storing the biometric template in the database increases the chance of compromising it which may lead to serious threat and misuse of the individual identity. This paper proposes a novel and computationally simpler approach to store a biometric sample in the form of template by using cryptographic salts. Use of Personal Image Identification (PII) makes the proposed algorithm more robust and adds another level of security. The saltcrypted templates are created and stored instead of storing the actual sample behaving as a fuzzy vault. The algorithm has been analytically proved computationally simple compared to the existing template security mechanisms. The fuzzy structure of saltcrypted template is entirely dependent on user interaction through PII. Actual template is not stored at any point of time which adds new dimension to the security and hence to individual identity.
