PROBLEM TO BE SOLVED: To prevent DRM information from being altered, and to prevent an image file from being reproduced.SOLUTION: A pixel packaging device 200 generates basic information data 112A for each of the pixels of an image file. The basic information data 112A includes an image file number for identifying an image file, a pixel number for identifying the pixel, the color or luminance of the pixel, and the DRM information or inventory information of the image file. The pixel packaging device 200 generates a pixel package file 110 including the basic information data 112A of all pixels as a file equivalent to an image file. A pixel package file distribution server 300 distributes the pixel package file 110. A pixel package file reproduction terminal 400 determines whether to permit the reproduction of an image based on the DRM information for each basic information data A, and displays the image when the reproduction of the image is permitted with respect to all basic information data 112A. |
