Abstract

A security system is provided. The security system includes a terminal system and a smart card. The terminal system generates relative fingerprint information of a user from absolute fingerprint information of the user, determines a similarity between the generated relative feature information of the user and registered relative fingerprint information of a smart card owner transmitted from the smart card to generate variation information, and applies the variation information to the user absolute fingerprint information to generate modified user absolute fingerprint information. The smart card determines the similarity between the modified user absolute feature information and registered absolute feature information of the smart card owner to perform a certification operation.
