Abstract
There is provided a method for authenticating a fingerprint. The method includes receiving an inputted fingerprint image; selecting a plurality of comparison target pixels from pixels in the inputted fingerprint image and selecting a plurality of comparison reference pixels from pixels in a pre-stored registered fingerprint image; and determining a similarity of an overlapping area where the inputted fingerprint image overlaps the registered fingerprint image whenever a matching arrangement of each of the comparison target pixels is made with respect to each of the comparison reference pixels. The method further includes, whenever it is determined that the overlapping area is similar, comparing the inputted fingerprint image and the registered fingerprint image within the overlapping area to calculate a correlation score with respect to the overlapping area and authenticating the inputted fingerprint image based on the calculated correlation score.
