Abstract: A method and a system enable authentication of large numbers of enrolled persons. At a biometric sensor, current biometric features of a person are recorded. At a matching server, currently recorded biometric features of the person are compared with prestored biometric features of enrolled persons while applying one or more identifying acceptance tolerances, and positive authentication is signalled in case of a match. At a user device of the person, in case of no positive authentication at the matching server, selecting prestored biometric features of the person at the matching server is enabled for comparison with the currently recorded biometric features while applying a verifying acceptance tolerance, and positive authentication is signalled in case of successful verification.

Abstract: A method of authentication using surface paper texture includes steps of capturing a topographic pattern image of a surface of a region of interest of the paper artifact and extracting a plurality of specific features from the captured topographic pattern image. The method further identifies the location of the specific features of the paper artifact from the captured topographic pattern image. A bit map of the identified location of the specific features is generated. Then, a reference image of a reference bit map printed on the region of interest of the paper artifact is captured. Finally, the method compares the generated bit map with the captured reference bit map to generate a score. The score of the comparison determines the level of authentication. The method provides an offline method of authentication.
