  • This type of protection also includes so-called self-verifying banknotes, as described in the document WO 98/15418 A1 are disclosed.
  • the self-verifying banknote described therein is formed from a flexible sheet of a plastic substrate with identification marks.
  • the sheet has a transparent window area containing a self-verification means for checking a security element located in a laterally spaced area of the sheet.
  • the self-verification is performed by bringing the window portion into register with the security element by bending or folding the sheet, and the security element and the self-verification means cooperate there appropriately to confirm the authenticity of the banknote.
  • the publication EP 1 127 712 A1 discloses a security and / or value document, in particular banknote, with security features and with a verification element for verifying the security feature.

  • WO 03/054810 A2 is a document of value known, in particular a banknote, which has one or more window areas, each with an example optically active element which rotates a polarization plane of passing through the window area polarized light by a defined angle. If such value documents are stacked and polarized light is emitted through the overlapping window areas, the number of stacked value documents can be determined on the basis of the total rotation of the plane of polarization. In the case of banknotes, the total nominal value of the banknote stack can thus be determined.
  • the window areas can have category-specific rotational characteristics for different categories or nominal values and / or can be present at category-specific positions in the value document.
  • the publication US 2003/0169468 A1 relates to a security system, in particular for value documents, in which a security element is provided in a carrier plane which reconstructs a pattern holographically outside the carrier plane, a pattern in which a hidden information is stored, and with a flat, transparent verification element, the surface contact of the security element makes the information stored therein readable. Furthermore, the invention relates a security element and a verification element for use in the security system, and a value document equipped with the security system. In addition, the invention relates to a device for reading the hidden information, which is holographically stored in the pattern reconstructed under the incident light on the security element.
  • the object of the invention is to provide a safety arrangement which avoids the disadvantages of the prior art.
  • the security arrangement should combine a high security against counterfeiting with a high recognition security even by laymen.

  • a damage-free examination of the authenticity feature of a safety arrangement is exclusive can be carried out via a predetermined combination effect with a verification element of a security arrangement arranged on another similar security document, thus excluding a self-certification. This measure ensures that the user has to take a second copy of the security document, for example a second similar banknote, at hand during the authenticity check.
  • the authenticity feature of a security arrangement is tested in a predetermined relative position of the authenticity feature and the verification element.
  • the predetermined relative position may be, for example, a superimposition of authenticity feature and verification element with a certain distance. This distance can be given for example by the focal length of a lens or the normal reading distance of a human.

  • the authenticity feature and the verification element of the same security arrangement can be coordinated with one another such that the authenticity feature and the verification element of the same security arrangement in the predetermined relative position does not show the predetermined combination effect. In both cases, the self-authentication of the security document is effectively prevented, the user is forced to use a second similar document for the authenticity check.

  • the authenticity feature contains an area printed with metameric colors. Metameric colors have different reflection spectra, but appear to the human eye in the same hue due to the sensitivity curves of the three color receptors in ordinary daylight illumination. The underlying difference of the reflection spectra, however, occurs with colored illumination of the metameres or when using suitable filters.
  • the verification element therefore expediently comprises a filter element for viewing the metameric color range of other security arrangements arranged on similar security documents.
  • the authenticity feature comprises a first linearly polarizing window region and the verification element a second linearly polarizing window area.
  • authenticity feature and / or verification element also comprise further polarizing regions. Due to the interaction of the different directions of polarization when bringing the different areas over one another, a series of different authenticity tests can be carried out by the contrast effects that occur.
  • the authenticity feature and the verification element each comprise, according to a further preferred embodiment, a fine line pattern which generates interference effects, in particular moiré effects, when the authenticity feature and the verification element are arranged one above the other.
  • the authenticity feature and / or the verification element for checking the authenticity feature may have a diffractive diffraction effect, a lens raster effect, a liquid crystal effect, or a thin-film or multilayer film effect.
  • the security arrangement contains at least two verification elements for checking the authenticity features of others of the plurality of similar security documents.
  • the verification of the authenticity feature is carried out while simultaneously using two or more of the verification elements, which are arranged on one or more of the plurality of similar security documents.
  • the two verification elements can be arranged at eye relief and be designed in the manner of a stereo eyeglasses, wherein the authenticity feature of a security arrangement when viewed through the two verification elements one on another security document applied safety arrangement causes a three-dimensional image impression.
  • two verification elements and the authenticity feature must be superimposed in a predetermined order.
  • the bringing together of the two required for checking the verification elements of a security arrangement makes the authenticity feature of the same security arrangement inaccessible. If the two verification elements are brought one above the other by a certain bending or folding process, then it can be provided, for example, that the authenticity feature is folded together by this bending or folding process and thus becomes accessible. Alternatively, this bending or folding process can automatically bring an opaque cover layer onto the authenticity feature, which prevents subsequent verification.
  • the verification element for the security document may also be characteristic, so that a check of the authenticity feature can only be carried out with those security arrangements whose verification element has a characteristic design corresponding to the authenticity feature.
  • the authenticity feature and the verification element can be characteristic for the particular denomination of a banknote, so that banknotes of a particular denomination can only be verified with other banknotes of the same denomination.

  • the two verification elements 146 and 148 are arranged directly next to one another on the banknote 140, so that they can be stacked on one another by folding the banknote 140 about the center line 150 of the two elements.
  • the centerline 150 divides the authentication feature 144 into two halves, such that the juxtaposition of the two verification elements 146 and 148 simultaneously folds the authentication feature 144 into itself by folding the bill. This ensures that the authenticity check can not be carried out with a banknote 140 alone, since the authenticating feature 144 is no longer available in the required form if the verification elements have been placed on top of each other.
  • Fig. 14 (a) shows a first variant of the authentication of a provided with the security arrangement 142-1 banknote 140-1.
  • a second similar banknote 140-2 is folded so that its two verification elements 146-2 and 148-2 are superimposed in this order, and the folded banknote 140-2 is placed on the first banknote 140-1.
  • the two banknotes are shown in the figure with a small distance.
  • the authenticity feature 144 selectively reflects in its first partial region 152 right-circularly polarized light, which in its second partial region 154 is selectively left circularly polarized.
  • the ⁇ / 4 layer of the first verification element 146 converts this circularly polarized light into linearly polarized light with mutually perpendicular polarization directions.
  • the subsequent linear polarizing layer of the second verification element 148 is oriented in the exemplary embodiment in such a way that it transmits the light originating from the second partial region 154 and blocks the light originating from the first partial region 152.
  • the motif in the embodiment, the number "5" then appears black against a light background.
  • the authenticity check can also be carried out with three similar banknotes, as in Fig. 14 (b) shown. Unfolded second and third banknotes 140-2 and 140-3 are placed on the banknote 140-1 to be checked. The banknotes must be superimposed in such a way that the authenticity feature 144-1 of the first banknote 140-1, the first verification element 146-2 of the second banknote 140-2 and the second verification element 148-3 of the third banknote 140-3 are stacked in this order lie. In this configuration, the information of the authentication feature 144-1 can be read out as described above.
