PROBLEM TO BE SOLVED: To provide an image processing device which has an authentication function of high versatility. SOLUTION: When image data accumulated in a storage section 4 are outputted, an input demand for key data for decoding the coded image data is performed. The coded image data are decoded at a decoding section 5 from the key data which are inputted from an user interface 7 by the input demand, and the validity of the decoded image data is presumed by a presumption section 6. Then, it is determined whether the decoded image data are image data which have correctly been decoded or not from the presumption result presumed by the presumption section 6. When the decoded image data are determined to be image data which have correctly be decoded, the output of the decoded image data is allowed. COPYRIGHT: (C)2006,JPO&NCIPI |
