摘要

PROBLEM TO BE SOLVED: To provide an abstract data generating method generating credible abstract data from original data. SOLUTION: When an abstract generation request including an original ID and an extraction tag list is received, the original data 11 specified by the original ID are read from an original storage medium 7, and an original data falsification detecting process is applied to the original data 11. If no falsification is detected, the data corresponding to the tag specified by the extraction tag list are extracted from the read original data as extracted data 12. The original ID and the extraction tag list are combined to form extraction range data 13, and the extracted data 12 and the extraction range data 13 are combined to form abstract contents data 14. An abstract falsification detection code calculation process is applied to the abstract contents data 14 to obtain a falsification detection code 15, and the abstract contents data 14 and the falsification detection code 15 are combined to form abstract data 16. The abstract data 16 are finally returned to an abstract generation requester.
