HASH VALUE GENERATION APPARATUS, SYSTEM, DETERMINATION METHOD, PROGRAM, AND STORAGE MEDIUM

摘要

PROBLEM TO BE SOLVED: To discriminate unknown data to a specified class with high accuracy and at high speed.SOLUTION: A hash value generation apparatus that generates a hash value for discriminating unknown data to a specified class or an unspecified class comprises: generation means that generates hash function information including a hash function on the basis of a specified feature amount indicating a feature amount of data belonging to the specified class; conversion means that converts the specified feature amount into a hash value on the basis of the generated hash function information; and storage means that stores the converted hash value as a normal hash value in association with the hash function information.
