An information processing device includes circuitry to generate content based on image data of an original image drawn on a medium. The content is available for use with a terminal device. The circuitry further acquires identification information uniquely identifying the original image. The circuitry further registers the generated content and the acquired identification information, in association with each other. The content and the identification information are registered in association with each other, to an information acquisition destination from which the terminal device is to acquire information based on the identification information.
