Patents by Inventor Frederick Kiefer

Frederick Kiefer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Fast, high-accuracy, large-scale fingerprint verification system
    Patent number: 10002285
    Abstract: Apparatuses, systems, and techniques are disclosed for rapidly identifying potential candidates within a pool of enrolled fingerprint images for unconstrained fingerprint matching with an inquiry fingerprint. The techniques may include applying one or more window regions to both enrolled and inquiry fingerprint images and determining a minutiae score for each such window region based on the minutiae within that window region. One or more components of the minutiae score for window regions of the inquiry image may then be compared against similar components in the minutiae scores for window regions of the enrolled fingerprint images, and enrolled fingerprint images having window regions with minutiae scores sufficiently similar to the minutiae score of a window region of the inquiry fingerprint image may be selected for later unconstrained matching with the inquiry fingerprint image.
