Apparatus For Storage Of Fingerprint Data Using Secret Distribution Technique, System For Authentication Of Fingerprint Data Using Secret Distribution Technique, And Method For Authentication Of Fingerprint Data Using Secret Distribution Technique

摘要

The invention fingerprint authentication device, method, relates to a system, especially based on the security token of the authenticated user relates to a fingerprint authentication apparatus and the information storage device using a secret sharing scheme, the fingerprint authentication method, the fingerprint authentication system. ; more specifically fingerprint authentication system of the present invention is a fingerprint storage, the authenticated user extracting feature points from the fingerprint information of the fingerprint image and that of the false feature point information generated by inserting the fingerprint information generating unit, classified according to the degree of dispersion in the characteristic point based on the fingerprint center of the fingerprint information and the fingerprint in accordance with the dispersion degree fingerprint information and outputting the distributed information distribution unit, and includes a first fingerprint and the second fingerprint information storage unit that stores the distribution information storing fingerprint information outputted in accordance with the degree of dispersion. Also characterized in that it converts the input fingerprint information and the fingerprint information registered alignment with a second fingerprint information storage unit based on the alignment and the part of the authentication information of the user fingerprint information, registered fingerprint information in the first storage unit.
