Abstract: An authentication apparatus including an input interface to acquires an image of a hologram label on an access object including key information; a processing history storage table that correlates a first image with the key information and stores the correlated image; an information determination circuit that refers to the processing history storage table, based on key information included in a second image that is being acquired after the first image, and determines whether the key information corresponds to key information of the second image; and a processing determination circuit that compares feature data of the second image that is not key information with feature data of the first image that is not key information in response to the information determination circuit determining the key information of the first image as being present, and uses the results of the comparison to determine whether to execute processing using the second image.

Abstract: An integrated three-dimensional display includes a recording surface which includes a calculated element region in which phase components of light from light converging points of a holographic reconstructed image are calculated, and a phase angle recorded area for recording a phase angle calculated based on the phase components. The phase angle recorded area includes a plurality of monochromatic regions having a uneven structure surface. The phase angle is recorded in an overlap area in which the calculated element region and the phase angle recorded area overlap each other. Light converges on the light converging points at specific distances from the recording surface, the specific distances being determined for the respective light converging points even when light reflected from the plurality of monochromatic regions converges.

Abstract: Provided is an information display medium that can enhance a forgery prevention effect. An information display medium (100) includes a light reflection layer (20) made of a metal or a metallic oxide and partially or fully placed on one surface of a substrate, and the light reflection layer (20) includes a first region (30) where first information is displayed by either of or a combination of an outline shape and a shape of an uneven region, and a second information display region (21a) where identification information formed by partial material removal of the light reflection layer (20), the second information display region being set to partially or fully overlap with the light reflection layer (20) where the first information is displayed in the first region (30).

Abstract: A display body includes a first surface, a second surface, a first optical component, and a second optical component. The first surface includes a first optical surface and a second optical surface. First light is incident on the first surface from an observation side. The second surface is located opposite to the observation side with respect to the first surface. Second light is incident on the second surface from a side opposite to the observation side with respect to the second surface. The first optical component forms first information, which is displayed on the observation side, from the first light received on the first optical surface. The second optical component receives the second light transmitted through the second surface, forms second information, which is displayed on the observation side, from the second light, and emits the second information from the second optical surface.

Abstract: A display body includes a first display part, which displays first information, and a second display part, which displays second information of a larger display size than the first information. The second display part includes the entire first display part as a part of the second display part. The first display part has a plasmon structure. The plasmon structure includes an interface between a metal layer and a dielectric layer, which transmits light, and is configured so that surface plasmons are excited in the interface to change irradiation light with which the interface is irradiated to transmitted light having a color different from that of the irradiation light. The first information is displayed with the transmitted light.
