Provided are a hinged laminate body, a booklet, and a laminate body that are able to increase the installation area of a member for authenticity determination. A hinged laminate body is configured so as to be able to increase the installation area of a member for authenticity determination by being provided with: an upper transparent layer; watermarked paper that is arranged below the upper transparent layer; and a hinge layer that has a hinge portion protruding from the upper transparent layer in a plan view and that is arranged below the watermarked paper. The watermarked paper of the hinged laminate body is provided with: an inner watermarked paper section that is arranged between the upper transparent layer and the hinge layer; and an outer watermarked paper section that is provided to the hinge portion so as to be arranged contiguously with the inner watermarked paper section.

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).

A security sheet including at least one paper substrate, at least one watermark produced in the paper substrate, the watermark having an exterior outline, at least one aperture of regular edge, produced by ablation of the paper substrate, and at least one security film that is at least partially superposed on the watermark and on the aperture. In the sheet, the at least one aperture lies inside the watermark, such as bounded by its exterior outline.

A prism layer has an uneven surface that includes at least one display region. An interface layer is adjacent to the uneven surface. The interface layer has a difference in refractive index from the prism layer such that a refractive index of a side of an interface between the uneven surface and the interface layer at which the prism layer is located is higher than a refractive index of a side of the interface at which the light interference layer is located. The display region includes inclination elements. The inclination elements adjacent to each other in an array direction contact each other in a plan view facing a plane along which the prism layer expands. The inclination elements include first inclination elements among which the inclination angle increases by the even angles along the array direction.

This disclosure relates to advanced image signal processing technology including encoded signals and digital watermarking. One claim is directed to a container comprising: a 3004 or 3003 aluminum alloy shell, the 3004 or 3003 aluminum alloy shell comprising an outer surface and an inner surface; a 5182 aluminum alloy lid attached to the 3004 or 3003 aluminum alloy shell; and an opaque ink printed on the outer surface in a 2-dimensional pattern according to a machine-readable signal. The outer surface and the opaque ink printed on the outer surface comprise a spectral reflectance difference at a machine-vision wavelength in a range of 8%-30%, and the machine-readable signal is detectable from imagery representing the opaque ink printed on the outer surface. Of course, other containers, technology, methods, packages, objects, systems and apparatus are described in this disclosure.
