This image information verification device extracts, from a face photo, a feature value ('a facial feature point position of an eye, a nose, a corner of a mouth, or the like', 'an image obtained by cutting off only an eye portion that characterizes a face', or the like) with a small data amount by which the face photo can be uniquely identified, and embeds the feature value as data for authenticity verification in a two-dimensional code, thereby enabling display on a display and verification of the authenticity of a digital identification card (image).
