<P>PROBLEM TO BE SOLVED: To provide an image information generation method, an image information authentication method, and a program by which new image is recognized from amplitude information of orthogonal transformation. <P>SOLUTION: The orthogonal transformation is performed to image data of n×n pixels, coefficient data is calculated at a position of n×n, absolute values of the calculated coefficient data are arranged in an descending order, ranks are assigned to the arranged coefficient data, positions of the coefficient data to which the ranks are assigned are detected and image information is generated by associating the assigned ranks of the coefficient data with the detected positions. <P>COPYRIGHT: (C)2007,JPO&INPIT |
