PROBLEM TO BE SOLVED: To provide a management device and an image processing system that can reproduce image data having higher resolution as a larger amount of distributed data is collected and secure security to copyright, privacy, etc. for each distributed data.SOLUTION: A resolution converter 104 converts input image data to N types of image data having different resolutions (N represents plurality). A secrete dispersion processor 106 executes secrete dispersion processing so that each of the plural image data is distributed into distributed data of n (n represents an integer of (N+1) or more and has the same value in all the image data), and original image data can be restored by using dispersion data of k (k represents an integer from not less than 2 to not more than n, and has a different value every image data). A data coupler 107 couples the distributed data which are selected one by one from the respective resolutions without duplication to generate coupling data of n, and stores the respective coupling data in different pieces of storage.SELECTED DRAWING: Figure 2 |
