  • Quality history for biometric primary data
    Publication number: 20050152598
    Abstract: A method is provided for the detection of biometric characteristic data for authentication. According to the invention, the quality of the characteristic data is statically evaluated, and the statistical evaluation is used as another data set for authentication.

  • Authentication with biometric data
    Publication number: 20050129289
    Abstract: An authentication method is provided for biometric characteristic data, especially characteristic data taken from finger-prints. The characteristic data is captured at least twice for each authentication request, and a position alteration between successive captures is evaluated and rated.

  • Method of automatically triggering pattern recognition procedures
    Patent number: 6901165
    Abstract: The method enables automatic triggering of pattern recognition tasks. A histogram of the frequency distribution of the gray-scale values of the image is determined periodically and repeatedly from the available image information. The characteristics of the histogram are determined, and the characteristics are used as the basis for establishing whether a relevant pattern is present. If the relevant pattern is found to be present, the pattern recognition process is initiated.

  • Method for producing a reference image for pattern recognition tasks
    Patent number: 6668072
    Abstract: A reference image for pattern recognition tasks is produced. Overlapping individual images are combined to form an overall image and the overall image is used as the reference image. This allows the size of reference images for fingerprints, for instance, which has hitherto been governed by the sensor area, to be increased. The recognition rate can thus be improved.
