  • Data carrier having an optically variable element and methods for producing it
    Patent number: 6954293
    Abstract: The invention relates to a system comprising a series of data carriers, in particular identity cards, papers of value or the like, whereby the data carriers belonging to the system exhibit diffraction structures containing standard information and parts of the series are changed by additional measures in the area of the diffraction structures or combined with other elements and they differ from the rest of the series in optically recognizable fashion, whereby the change in the diffraction structures and/or the combination with other elements convey an esthetic overall impression and the change and/or combination with the other elements cannot be undone without destruction of the diffraction structures.
    Type: Grant

  • Method of producing a document with an unforgeable surface relief
    Patent number: 5433807
    Abstract: Documents and data, patterns, etc., applied thereto, which are present in the form of a surface relief, in particular in the form of embossed characters, are provided partially in the area of this surface relief with luminescent substance which is testable visibly and by machine. The luminescent substance is introduced either into raised or into depressed areas of the surface relief, so that characteristic features of the surface relief are reflected in its spatial distribution. The data can thus be tested for falsification and at the same time for authenticity in a simple way.
