Abstract: A method is provided that determines authenticity of a second recording medium mounted in a second device by using a first device mounted with a first recording medium. A non-user area of the first recording medium previously records first identification information and first algorithm data. A controller of the first recording medium causes a first display device to display a first image pattern and, after display of the first image pattern, causes a first imaging device to capture a second image pattern displayed on a second display device of the second device. The controller decodes first code data from the second image pattern and utilizes the first algorithm data to perform arithmetic that uses the first identification information and a first variable value. The controller determines the second recording medium to be authentic if the decoded first code data matches an arithmetic result.
