This paper describes a physical access control system with biometric authentication. An advantage of biometric-based systems is that users do not need to remember passwords or carry smart cards for their authentication. It is very important, however, to understand that the biometric information stored in the system as templates is a big privacy concern. Moreover, in terms of digital forensics, the physical access control system is required to maintain an accurate and secure log of persons who got authentication checks. To obtain both template protection and log protection, this paper proposes to use a biometric-key generation scheme in a physical access control system with biometric authentication.
