Using cyclic redundancy check to eliminate key storage for revocable iris templates

In recent years, with the increased use of biometrics for user authentication, an increase in the demand for the security of the biometric databases has occurred. Public concerns about safety of their biometric templates if the database is compromised as well as fears of cross-referencing among databases had to be addressed to ensure public acceptance of the use of biometric systems in large scale applications. In this paper, we propose a template protection system for iris- based biometric systems. A shuffling algorithm ensures revocability, while a combined Hadamard and Reed Solomon error correction coding ensures security, and as an improvement over previous research, cyclic redundancy check is introduced to eliminate the need to store user keys along with the templates in the database.
