摘要

PROBLEM TO BE SOLVED: To reduce the time required for collation irrespective of the version of definition information for the collation.SOLUTION: A computer program to be executed in the information processor that includes: an information acquisition part which acquires external information for specifying processed data collated based on collation definition information by a hash value and showing a processing result of the processed data, by network communication; a hash operation part which generates the hash value using a hash function applied to generation of the hash value of the external information from data stored in a storage medium; and an object screening part which excludes the data stored in the storage medium from objects to be collated when the hash value generated by the hash operation part matches the hash value of the external information.
