Abstract: In producing a film by printing on a top sheet with non-glossy surface, a first glossy varnish imprint adheres on the surface. A second continuous imprint produced on the first, adheres neither on the top sheet nor on the varnish, and the film is completed. A glossy imprint is thus provided in the film external surface which is then applied on a document to protect it from being reproduced by optical scanning.

Abstract: Line art on a banknote or other security document is slightly changed to effect the encoding of plural-bit digital data (i.e. the banknote is digitally watermarked). When such a banknote is thereafter scanned, the resulting image data can be recognized as corresponding to a banknote by detection of the encoded data. (Alternatively, the image data can be recognized as corresponding to a banknote by machine detection of other forms of watermarking, or by reference to visible structures characteristic of banknotes.) In response to detection of a banknote, the detecting apparatus (e.g., a scanner, photocopier, or printer) can intervene so as to prevent or deter counterfeiting. For example, the apparatus can interrupt a copying operation, and display a message reminding the operator that it is illegal to reproduce currency. Another option is to dial a remote service and report the attempted reproduction of a banknote. Yet another option is to permit the copying, but to insert forensic tracer data (e.g.
