Abstract: PURPOSE: A digital fingerprint matching method is provided to determine trees where the number of singular points on a ridge stem extracted from inputted fingerprint data is identical to that on a ridge stem extracted from stored fingerprint data, and to check whether the singular points of the tree of inputted fingerprint data are identical to those of the tree of stored fingerprint data. CONSTITUTION: The method comprises several steps. If fingerprint data is inputted, singular points are set(210). A variable T, which is to be compared with an inverse value, is initialized as zero(220). Neighbor singular points are selected(230). A distance between the neighbor singular points is calculated(240). Singular point pairs are determined among the stored ones where the kind of the determined singular point pairs are the same as that of the selected neighbor singular points(250). It is checked whether there exist the singular point pairs whose distance are similar to those of the selected neighbor singular points. If there does not exit a pair, the value of T is increased by one, and then the value of T is compared with an inverse value. If the value of T is larger than the inverse value, the inputted fingerprint is not the same as the stored one. If there is a pair, the pair selected in the step 230 is the same as the pair determined in the step 250. Then, it is checked whether the number of singular points extracted from the inputted fingerprint is more than a reference. If the number is more than a reference, the inputted fingerprint is the same as the stored fingerprint.
