PROBLEM TO BE SOLVED: To make it possible to easily grasp leakage of information recorded on a recording medium.SOLUTION: Each time a scanner is used, an image data file is created and stored (S201). Then, OCR processing is performed (S202) to create an image data file and text data (S203). The read image data file is compared with the image data file stored in the past, thereby determining whether both of them match each other (S206). When they match each other (S206:YES), that effect is stored in a print log storage server as a print log. |
