Abstract: Disclosed is a method for detecting a latent fingerprint image provided to a biometric input device of a fingerprint based security system. First and second images of the fingerprint are captured during a time period interval &Dgr;t. At least one of the first and second images are analyzed to identify an extractable feature within a global reference frame, the extractable feature useable for authenticating an individual. The first and second images are compared one with the other to determine differences indicative of motion about the identified extractable feature within a local reference frame during the time period interval &Dgr;t. Absent motion about the identified extractable feature being detected, the fingerprint is registered as a latent fingerprint and cannot be used to authenticate the individual who is seeking authorization.

Abstract: An improved method and system for reading and analyzing fingerprints is disclosed. According to the present invention, fingerprints are scanned and then analyzed to determine a value in dependence upon a predetermined acquisition parameter, such as for instance one of a moisture content of the fingertip and an applied fingertip pressure. The scanned fingerprint is subsequently processed to remove “false minutiae” in dependence upon the determined value, whilst retaining authentic minutiae for user authentication. Processing the fingertip to determine a condition thereof prior to image processing results in a more selective removal of minutiae, thus resulting in a larger set of minutiae being retained for comparison to a stored biometric template.
