摘要

PROBLEM TO BE SOLVED: To rapidly process generation of an alteration detection digest value. SOLUTION: An alteration detection information generating apparatus includes: a memory means for storing image file data; an image data division means for dividing image data included in the image file data stored in the memory means into a plurality of division image data; a plurality of hash arithmetic means corresponding to the plurality of division image data and operated in parallel to perform hash arithmetic operations, and the plurality of hash arithmetic means obtain a plurality of digest values corresponding to the plurality of division image data.
