VLSI Architecture of the Fuzzy Fingerprint Vault System
User authentication using fingerprint information provides convenience as well as strong security at the same time. However, serious problems may cause if fingerprint information stored for user authentication is used illegally by a different person since it cannot be changed freely as a password due to a limited number of fingers. Recently, research in fuzzy fingerprint vault system has been carried out actively to safely protect fingerprint information in a fingerprint authentication system. In this paper, we propose hardware architecture for a geometric hashing based fuzzy fingerprint vault system. The proposed architecture consists of the software module and hardware module. The hardware module performs the matching for the transformed minutiae in the enrollment and verification hash table. We also propose a hardware architecture which parallel processing technique is applied for high speed processing.
