Method for memory efficient concealment and memory efficient authentication of fingerprint data using fuzzy vault, Apparatus and System thereof

摘要

Memory efficient fingerprint data hiding method using Fuzzy bolt, bolt fuzzy memory efficient data authentication method using a fingerprint, fuzzy vault memory efficient fingerprint using a memory efficient fingerprint data concealment device and fuzzy vault for data authentication system is disclosed. ; The present invention using a sensing device receiving a fingerprint of the certificate user, extracting the fingerprint information that is composed of feature points in said fingerprint image, to produce a first polynomial to the extracted fingerprint information by a factor, fake step feature points randomly generating a plurality of fake fingerprint information consisting of, inserts the generated fake fingerprint information in the extracted fingerprint information to generate concealment fingerprint information, a plurality of feature points other than the false feature points in the concealment fingerprint information classifying into groups, select any of the feature point as a reference point for each of the groups, and moving the position of the selected feature points as the origin and change the angle to the reference angle, corresponding to the selected feature point to geometrically move the remaining fingerprint information the step and the first polynomial, and the memory efficient registration hash table by repeating the process for each of said group generate the memory efficient registration hash table comprises storing in the database. ; According to the present invention, the load on the system at by applying the fuzzy vault theory and apply the memory efficient geometric hashing techniques, the recognition rate and without degrading the security server effectively reduces the size of the hash table, the embedded system in order to secure the biological information reduce the number, and polynomial in the certification process of the restoration process by using fingerprint information to the aiding information to restore the original fingerprint to authenticate without having completed it can be hacked fingerprint information for improving safety to be there.
