PROBLEM TO BE SOLVED: To provide an image processing device which is capable of preventing an authentication code from leaking out and ensuring security. SOLUTION: When an image data input (S301) is carried out, image data are transmitted to an image processing device B and stored in a memory (S304). Authentication code data are formed for the image data (S305) and stored in a storage medium, and the authentication code is inputted into the image processing device B (S303) when an indication that authentication code is read out is issued (S302). The image processing device B receives image data, stores them in a storage medium (S306), and forms authentication code data (S307). The authentication code is collated (S308), and when it is found that the authentication code is identified, the image is outputted (S309). When the authentication code is not identified, a warning is displayed (S310).
