<P>PROBLEM TO BE SOLVED: To provide an authenticity determination support unit, an authenticity determination device, an authenticity determination support program and an authenticity determination program that contribute to high-accuracy authenticity determination. <P>SOLUTION: An authenticity determination device sequentially executes: a step 110 of clipping a compression target image from a retrieved feature image; a step 112 of determining a compression direction and a compression ratio of the compression target image by analyzing a result obtained by applying two-dimensional FT or FFT to the compression target image clipped in the processing of the step 110; a step 116 of clipping a reference image for authentication determination from a compressed image that is obtained by compression in the processing of the step 114; and a step 118 of, after the step 116, registering information that includes the compression direction and the compression ratio determined in the processing of the step 112 which are associated with the reference image clipped in the processing of the step 116, by storing the information in a secondary storage unit as master data, with respect to each predetermined area. <P>COPYRIGHT: (C)2013,JPO&INPIT |
