Abstract: Systems and methods for biometric authentication are disclosed. The invention may be used to authenticate an individual. At least two enrollment templates may be obtained at different times. Later, an inquiry template may be obtained and compared to each of the enrollment templates in separate and distinct comparison operations. The match scores arising from the comparison operations may be fused to provide a composite match score. The composite match score may be compared to an acceptance range. If the composite match score is within the acceptance range, the individual may be authenticated.

Abstract: Embodiments of apparatus, computer program product, and method for verifying fingerprint images are disclosed. In one embodiment, a method of verifying fingerprint images includes receiving an inquiry fingerprint image of a user, identifying pattern characteristics of the inquiry fingerprint image, identifying minutiae characteristics of the inquiry fingerprint image, determining a weighted combination of the pattern characteristics of the inquiry fingerprint image and the minutiae characteristics of the inquiry fingerprint image, where the weighted combination comprises a pattern matching weight and a minutiae matching weight derived in accordance with a separation of a first empirical probability density function of genuine fingerprints from a second empirical probability density function of impostor fingerprints, and verifying the inquiry fingerprint image based on a set of fused scores computed using the weighted combination of the pattern characteristics of the inquiry fingerprint image and the minutiae characteristics of the inquiry fingerprint image.
