VLSI ARCHITECTURE FOR THE FUZZY FINGERPRINT VAULT SYSTEM AND MATCHING METHOD THEREOF

摘要

A VLSI structure of a fingerprint purge bolt system and a fingerprint authentication matching method are disclosed. The VLSI structure of the fingerprint fuzzy bolt system according to the present invention extracts a registration feature point from a registration fingerprint image for registration, generates a fingerprint template by inserting a false feature point into the extracted registration feature point, and geometric hashing of the generated fingerprint template. A registration processing module for generating a registration hash table for performing automatic sorting based on the method and storing the registration hash table in a database; An authentication processing module for extracting an authentication feature point from an authentication fingerprint image for authentication and generating an authentication hash table for performing automatic alignment on the extracted authentication feature point based on a geometric hashing method; And calculating a similarity level by comparing the conversion feature point of the registration hash table with the conversion feature point of the authentication hash table, and determining whether to authenticate the authentication fingerprint image according to the result.
