The identification document comprises a personalized area carrying owner-specific information, such as an owner's name data or photograph, The personalized area is overlapped by a lightguide, The lightguide comprises a primary incoupler and a primary outcoupler on opposite sides of the personalized area. Any attempt to tamper with the personalized area may lead to a damage in the lightguide, which can easily be detected by coupling light into the primary incoupler and testing the light coupled out by the primary outcoupler.

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.

The present invention relates to a security device comprising a colloidal crystal which exhibits excellent visibility and is also easily manufactured. The security device, according to the present invention, comprises: a substrate; a groove part formed on the substrate; a colloidal crystal positioned in the groove part; and an aging film. The security device, according to the present invention, exhibits excellent security and visibility, and thus may be used for securities, credit cards, security cards, anti-forgery products, etc.

An optically variable security element is provided for protecting objects of value. The reflective area region includes two independent relief structures, which are arranged at different levels in the z-direction and form a lower-level relief structure and a higher-level relief structure. The higher-level relief structure is supplied with a first reflection-enhancing coating following the relief profile, and the lower-level relief structure is supplied with a second reflection-enhancing coating following the relief profile. The first reflection-enhancing coating is formed in the visible spectral range with a reflection and transmission in the visible spectral range, so that the higher-level relief structure shows a first optically variable effect in a first color, and the lower-level relief structure shows a second optically variable effect through the first reflection-enhancing coating, wherein the second optically variable effect shows itself in a second, different color.

The present invention relates to a flexible package for providing security against counterfeiting. The flexible package includes a plurality of panels made of a flexible polymeric substrate, which further includes a front panel, a rear panel arranged in opposite to the front panel defining an interior space of the package and at least one longitudinal narrow window portion on at least one panel. A transparent or translucent polymeric security strip is having a clear high barrier coating, is sealed over the window portion towards inner side of the panel overlapping the edges of the window portion but not overlapping the entire panel, a security feature is provided on the strip on at least one of its surface at a predefined location or random places or all over the strip surface for securing the package against counterfeiting.

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 method and associated system for authentication, including irradiating an item including a polymer security thread including a polymer material and a doping material within the polymer material and configured to produce a radiation spectrum in response to the irradiating, the doping material capable of absorbing, scattering, or emitting radiation, and detecting the produced radiation spectrum to confirm the presence of the polymer security thread.

A packaged redeemable code system is disclosed. The packaged redeemable code system includes a paper insert having a front surface with a removable item, and a rear surface with redeemable code. The packaged redeemable code system further includes a paper sleeve having an interior that encloses the paper insert and conceals the redeemable code. The paper sleeve also having a ripcord configured to open an edge of the paper sleeve to provide an access point for removal of the paper insert. The paper sleeve further having a front surface with a cutout extending therethrough. The cutout aligns with and provides visual access to the removable item. The removable item is a different color than or provides contrast with the front surface of the paper sleeve. The paper sleeve further having a rear surface with an activation code that is associated with the redeemable code.

A method for manufacturing a two-dimensional colored bar code comprising an arrangement of colored basic structural elements encoding at least one information element, the manufacturing method comprising determining, by data processing means, a set of colored basic structural elements corresponding to the at least one information element, at least one structural element of the set comprising a pattern; and forming the at least one structural element of the set on a backing, in order to create the arrangement of colored basic structural elements.
