Abstract: The present invention relates to a method and a system for the local or remote authentication of an item, in particular a security document, with the help of a authenticating device, comprised in, connected to, or linked to mobile communication equipment. Said item carries a marking exhibiting a characteristic physical behavior in response to interrogating energy, such as electromagnetic radiation and/or electric or magnetic fields. Said marking may comprise physical and logical security elements, e.g. a barcode, or a characteristic particle or flake pattern, exhibiting a characteristic physical response.

Abstract: A pigment composition is disclosed, obtained from intaglio or engraved steel die printing ink wastes. The wastes containing pigment, ink resins, extenders, and other minor components, are dried, ground and sieved to give a dry pigment composition. This pigment composition is optionally blended with plasticizers to give a pasty composition.These compositions are useful to color and plasticize synthetic plastics materials such as sheetings, PVC leather and films.

Abstract: A process for preventing the counterfeiting of valuable documents through use of photography, photocopying techniques, or other methods of counterfeiting. The process includes laminating an extremely thin metallic film to the substrate of the valuable document before the document is printed with the area of the metallic film being small in comparison to the area of the document. The metallic film can be located anywhere on the face of the document and a "latent image" is embossed on the metallic film when the document is printed. Embossing the latent image on the metallic film, rather than on the document substrate, provides many advantages not possible in the prior art.A photocopy of a document containing the embossed metallic film does not include the latent image and a color photocopy will be different in color than the original document. Therefore, a lay observer can readily differentiate between a genuine document and a counterfeit document.
