Abstract: A computer-implemented method of registering image data in the context of a biometric security system includes receiving an indication of image data, detecting a first point set and a second point set, based on the image data, and generating a metric of closeness between the first point set and the second point set. In addition, the computer-implemented method includes applying the metric of closeness to a transformation model to obtain a transformation parameter and transforming the first point set with respect to the second point set, based on the transformation parameter. Further, the computer-implemented method includes determining whether transformation of the first point set with respect to the second point set indicates convergence and, if so, generating an output indicative of an aligned point set.

Abstract: Systems and methods for regulating user access in the context of a biometric security system are disclosed. One method disclosed includes receiving a remotely transmitted data packet containing an encryption key, utilizing a decryption component to decrypt the data packet, and utilizing the encryption component to encrypt biometric data. Another method disclosed includes utilizing a processor, within a client computing device, to perform an encryption function within a biometric security system, wherein the encryption function is incorporated into an authentication process that involves a transfer of biometric information between the client computing device and a remotely implemented server.

Abstract: A computer-implemented method for directionally characterizing an image element within an image is disclosed. The method includes obtaining an image segment and determining a directional representation value that corresponds thereto. The directional representation value is then utilized to directionally identify an image element other than the image segment.

Abstract: Methods and procedures for improving the performance and reliability of image analysis within an image identification system include a series of image qualification functions designed to quickly process a fraction of available image data and to provide feedback to a system user pertaining to image quality and authenticity. Functions designed to produce image models based on original image data and to catalogue such image models into a searchable database are included in the present invention. The present invention also includes functions for comparing one image model to another. Finally, the present invention provides functions for making a quick determination as to which, if any, of a potential thousands (or more, i.e., millions) of image models within a searchable database exhibit a desired level of similarity, as compared to a target image model.

Abstract: A computer-implemented method for enhancing the security of informational interactions with a biometric device is disclosed. The method includes pre-establishing an encryption relationship between a computing device and the biometric device. An instruction is received to begin an authorization or enrollment session. A session packet is generated and encrypted. The session packet is transmitted to the biometric device. A biometric information packet is received and decrypted. A determination is made, based on a content of the decrypted biometric information packet, as to whether or not to utilize a collection of biometric data contained in the decrypted biometric information packet.

Abstract: Biometric security systems are disclosed wherein a match template is unique as compared to a corresponding authentication model generated during enrollment and/or attempts at authentication. In accordance with one embodiment, the uniqueness of the match template as compared to a corresponding biometric authentication model is complete and non-reversible. Accordingly, the data in the match template cannot be directly utilized to produce an authentication model. Accordingly, match templates stored in a database need only be protected to assure that they are not substituted, altered or supplemented. Replication of match template data is not of paramount concern, as it cannot be used for a direct authentication.
