Latest Patents
Douglas C Knight holds a patent for a "Fingerprint correlation system with parallel FIFO processor." This invention presents a method and apparatus for parallel processing both live and pre-recorded reference fingerprint data for comparison purposes. The system utilizes an array sensor to image a selected portion of a live fingerprint, while video means produce corresponding digital live image data. The pre-recorded, multi-pixel reference data and the image data are scanned relative to one another using recirculating First-in-First-Out (FIFO) buffer memories along with row and column shift means. The technology employs Exclusive OR (XOR), summation, and accumulation circuitry to simultaneously compare the reference and image data over multiple correlation cycles, computing a correlation value for each cycle. A microprocessor is then used to determine the best correlation value from a tabular store of correlation values relative to a PASS/FAIL threshold.
