摘要

A check code generating means 10 generates, based on metadata of files satisfying a designated condition, a first check code uniquely representing a characteristic of a first file set whose components are files satisfying the condition. Moreover, the check code generating means 10 generates, based on metadata of files satisfying the condition, a second check code uniquely representing a characteristic of a second file set whose components are files satisfying the condition. An inconsistency detecting means 20 compares the first check code and the second check code and, based on inconsistency between the check codes, detecting inconsistency between the first file set and the second file set.
