PROBLEM TO BE SOLVED: To detect whether or not a plurality of data to be matched match in a short time and with a small processing load.SOLUTION: In an internal device 1B, when data C and a serial number "50" are lost, the data C and a serial number "40" are restored from a backup file. For example, when the data C are referenced, matching is determined in accordance with serial numbers "50", "50" of data A and B of an internal device 1A and a serial number "40" of the data C of the internal device 1B. That is, when those parameters are not the same parameter, it is determined that the data A, B and C do not match. |
