PROBLEM TO BE SOLVED: To enable only a specific person to restore and read the broken image data by moving and breaking digitally a digitized original image via the coordinate conversion that is set by input of the cipher numerical value to be given to a control command frame and securing the correspondence between a ciphered and recorded thawing key and the broken image data only. SOLUTION: A desired original image to be secured is recorded on the main software. Then a part or the whole of the original image is digitally moved and broken via the coordinate conversion that is set by input of the cipher numerical value to be given to a control command frame within a range where the image of the original image is not lost. The broken image data are stored and also a ciphered and recorded thawing key that can correspond only to the broken data is issued and stored. This thawing key is given only to a specific user via a floppy or an internet. Thus, the user can restore and read the original image just by dragging and dropping the thawing key to the broken image. |
