ABSTRACT:
A fingerprint data registering method which can clearly show the characteristics of minutiae by storing the information of an original image. The method includes thinning a fingerprint image into an array of pixels, converting a pixel in each array into a multi-bit binary value corresponding to the pattern of the array, and storing the multi-bit binary value as the pixel.
