Abstract: The fingerprint recognition method is for discriminating the identity of two fingerprints by comparing break points and diverging points of fingerprints. The method comprises two steps: (A) comparing print patterns of the registered and the input finger prints and setting intervals; above upper boundary, between upper and lower boundary, and below lower boundary; (B) discriminating that two finger prints are identical or different if the difference belongs to upper boundary and lower boundary respectively; (C) if the difference is between upper and lower boundary, extracting the characteristic points of input finger print by preprocessing (19) and edge detection process and comparing the similarities.
