Abstract: In the past, user authorization based on biometric information was conducted by correlating a single instance of biometric information against a template. By using this method, a percentage of the population is difficult to authenticate. Further, due to skin damage and injuries, sometimes biometric information is not suited to identification. A sore throat affecting voice information and scraped finger tips affecting fingerprint information are two examples of common problems with authorization in dependence upon biometric information. A method of authenticating a user in dependence upon biometric input information is disclosed. The method allows a user to select biometric information sources and a number of repetitions for each source in order to customize the process of biometric user authentication.

Abstract: A non-minutia method and apparatus for comparing a reference fingerprint image to a candidate fingerprint image are disclosed. During enrollment of a reference image, a unique reference set of data is generated in a reference coordinate system by placing a group of line segments on the reference image. A collection of constraints is used for defining the subspace for each line of the reference group. A similar set of candidate line segments is constructed on the candidate fingerprint image in a candidate coordinate system. A candidate set of data is determined and then compared with the reference set of data using translation and rotation of the coordinate systems. Tolerances of the comparison are also provided for.
