Abstract
A method and apparatus for obtaining, hashing, storing and using fingerprint data related to fingerprint minutia including the steps of: a) determining minutia points within a fingerprint, b) determining a plurality of sets of proximate determined minutia points, c) subjecting a plurality of representations of the determined sets of minutia points to a hashing function, and d) storing or comparing resulting hashed values for fingerprint matching.
