  • Fingerprint sensor and method for processing fingerprint information
    Patent number: 10719690
    Abstract: A method for processing fingerprint information may include obtaining an input image corresponding to at least a region of a user fingerprint, searching a memory storing at least one registered image for a reference registered image that matches the input image at least partially, determining a unique region of the input image in which the input image does not overlap with the reference registered image when the input image is aligned with the reference registered image, and, in response to a score of the unique region of the input image being greater than or equal to a predetermined reference score, classifying the input image as belonging to a same group as the reference registered image and storing the input image in the memory.

  • Method of processing fingerprint information
    Patent number: 10509943
    Abstract: A method for processing fingerprint information includes dividing an input image that corresponds to at least a portion of a user fingerprint into a plurality of first regions; dividing a registered image that had previously been stored into a plurality of second regions; selecting a first matching region from among the plurality of first regions, and selecting a second matching region from among the plurality of second regions, by comparing the plurality of first regions with the plurality of second regions; and matching the registered image with the input image by comparing the first matching region with the second matching region.
