In the production of a document, image information is incorporated into a plurality of layers of the document such that the pieces of image information are combined into a total image. The image information in at least two of the layers includes digital watermark information. The entirety of the digital watermark information in the at least two layers forms a security feature for an authentication of the document. The invention further relates to a respective document, a method for authentication, and a device for authentication.

摘要:
A document including an integrated display device that has several triggerable display elements, each of which is designed to emit an optical signal for representing first data stored in the document whereby the display device is designed for cyclical activation of the display elements for rendering the first data in sequential image regeneration periods, and whereby the display device is designed in such a way that the emission of the optical signals of at least a subset of the display element takes place with a chronological delay, whereby it is not possible to visually perceive the chronological delay.

A method produces colored individualized holograms for use as security elements for documents, and to a device for producing individualized holograms. The method generates light formed of different colors, spatially modulates the light, color by color, in an individual manner, optically guides the modulated light such that the light is at least partially refracted and/or reflected on a holographic master and is superposed in a holographic recording material with the modulated non-refracted and/or reflected light, and records the hologram. The light is modulated, color by color and at the same time, by a plurality of spatial light modulators. Every color is associated with its own spatial light modulator and a plurality of monochrome modulated light beams of the plurality of colors is combined in a collinear manner prior to refraction and/or reflection on the holographic master and the superposition in the recording material to give a multicolor exposure light beam.

The invention relates to a personal document in the form of a book, comprising a book cover, a multi-layered personalised side which contains personalised data, in addition to inner pages. The personalised side and the inner pages are secured by means of a seam to the book cover. The multi-layered personalizing side is provided with a central area which is made of a textile layer which is joined on both sides to a thermoplastic layer which covers the central area until the projecting end. A RFID element comprising an IC element is integrated into the central area for the contactless transfer of biometric data of the personal document owner. The personalised side is sewn by means of a seam in the region of the projecting end.
摘要:
The invention relates to a data support (1) with a core layer (15) and at least one adjacent layer (14a), laminated to the core layer and a corresponding production method, said core layer being embodied from a holographic data store in the form of a volume hologram (5). The surface (141) facing the core layer, on the layer directly adjacent to the core layer, has a roughness (19), before lamination to the core layer, which affects the wavelength shift of the image reconstructed by the volume hologram.
摘要:
A document-examining apparatus is provided for automatically examining the authenticity elements of secured documents. It includes a compound slide which can be moved in the X and Y directions and on which the components required to evaluate the distinguishing authenticity features are mounted. The X slide of the compound slide is mounted on a Y slide. A first group of evaluating units for evaluating diffraction elements on a document is disposed on the X slide. A second group of evaluating components, for example, for evaluating text, an IR field and/or a photographic field, may be mounted on the Y slide. In addition, a source of UV radiation may be provided for examining distinguishing fluorescence features of a document, the fluorescence being evaluated by a stationary evaluating unit or by the evaluating unit on the X slide.

The present invention provides a secured document including a composition capable of anti-Stokes fluorescence containing an ion capable of absorption of electromagnetic radiation, an ion capable of emitting electromagnetic radiation, and a matrix composition comprising gadolinium, yttrium, lanthanum, and lutetium, wherein the wavelength of the emitted electromagnetic radiation is shorter than the wavelength of the absorbed electromagnetic radiation, and wherein the concentrations of the absorbing and emitting ions are adjusted to achieve concentration quenching of anti-Stokes luminescence.
摘要:
The present invention relates to a security document and/or value document, in particular banknote, with security features and with a verification element for verifying the security feature. The object of the present invention, to develop a generically compliant security document and/or value document, in which security against forgery is increased and the document can be inspected for genuinity more easily and without the use of external aids, is accomplished in that at least one verification element 2 and at least one security feature 3 to be verifiable by this verification element 2 are integrated into the document 1 in various positions, whereby the verification element 2 and the security element 3 are brought over each other only when verification is to take place.
