PROBLEM TO BE SOLVED: To provide an image conversion method in which, using the mathematically guaranteed means for preventing credibility as an image of data from being damaged while reducing the amount of image data, image data having confidentiality, by chance, prevents the possibility of being intercepted and altered by a third party, and also to provide an inverse conversion method thereof.SOLUTION: An information processing system includes: a conversion processing device for generating data of the converted image by applying the image conversion processing to original image data, in which a plurality of images are overlapped on each other or the images are overlapped by being continuously deviated by the amount of a predetermined size by a mathematical procedure determined in advance based on a repairable condition; and an inverse conversion processing device for executing the image inverse conversion processing which restores the converted image data to the original image by the mathematic procedure determined in advance based on the repairable condition.SELECTED DRAWING: Figure 1 |
