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

摘要

A hash value generation apparatus that generates a hash value for identifying unknown data as belonging to a specified class or an unspecified class, includes a generation unit configured to generate hash function information including a hash function based on a specified feature amount of data belonging to the specified class, a conversion unit configured to convert the specified feature amount into a hash value based on the generated hash function information, and a storage unit configured to store the hash value obtained by the conversion as a normal hash value in association with the hash function information.

1. A hash value generation apparatus that generates a hash value for identifying unknown data as belonging to a specified class or an unspecified class, the hash value generation apparatus comprising:
a generation unit configured to generate hash function information including a hash function based on a specified feature amount representing a feature amount of data belonging to the specified class; a conversion unit configured to convert the specified feature amount into a hash value based on the generated hash function information; and a storage unit configured to store the hash value obtained by the conversion as a normal hash value in association with the hash function information.
