Using a fuzzy logic control system, we propose in this paper an optimized method to reduce the points
number to be used in order to identify a person using fuzzy fingerprints. Two fingerprints are similar if
n out of N points from the skin are identical. We discuss a criteria to choose these points. Our method
compares two matching sets and selects the optimal set from these, using a fuzzy reasoning system
based on intuitionistic fuzzy numbers. The advantage of our method with respect to the classical existing
methods consists in a smaller number of calculations
