| description | PROBLEM TO BE SOLVED: To provide a method and system for securing data originality and a program for securing data originality which are capable of preserving data while more easily securing its originality.SOLUTION: A system 1 for securing data originality which preserves source data B while securing its originality comprises: a hash value generation part 11 which generates the hash value H of the source data B; a divided data generation part 13 which uses a secret dispersion method to divide the source data B containing the generated hash value H into a plurality of pieces of divided data D(1)-D(4) from which the source data B can be restored; and a plurality of preservation servers 3a1-3a4 which are independent in a hardware manner to respectively store the pieces divided of data D(1)-D(4). |
