Biometric authentication can provide an added level of security and/or ease of convenience in access control applications. Fingerprints are a popular choice among the biometric features and have been successfully used in criminal identification. In access control applications, we are interested in obtaining digital live-scan fingerprints from sensors, rather than the inked fingerprints usually used in criminal identification. In this paper, we evaluate the performance of composite correlation filters in fingerprint verification for access control applications. The NIST Special Database 24, obtained from an optical fingerprint sensor, is used to evaluate the performance of fingerprint verification in the presence of distortion.
