Definitions

  • the invention relates to a method for reading security features on value and / or security documents with the features of claim 1 and a corresponding device according to the features of claim 11.
  • the carrier can be, for example, a letter, large or maxi letter, on which the document of value is arranged in the form of one or more stamps.
  • Banknotes, ID cards, packaging, labels, stickers and tickets, in particular products which can be printed or otherwise provided with security features, are also considered to be value or security documents in the sense of the present invention.
  • the security features housed on or in the value or security document contain information that is usually not readily visible. Examples are magnetic or electromagnetic peculiarities, certain material properties as well as characteristics that can be detected in UV, IR and NIR. Typically, special sensors that are tailored to the respective case and that detect one or more of such properties are used for this.
  • DE 101 13 267 AI describes antistoke phosphors which, when excited with certain electromagnetic radiation, have characteristic luminescent properties, the emitted radiation being shorter-wave than the excitation radiation. Further luminescent substances which are suitable as security features for documents of value are described in DE 198 03 997 AI, WO 98/39392 AI, DE 199 17 887 AI.
  • the basic presence of the phosphor is determined on the value document.
  • the temporal emission curve of the luminescence can be determined (EP 1 158 459 AI).
  • DE 101 13 268 AI describes a system for checking the presence of a security feature on a document of value.
  • a line-shaped scanning line is generated, the length of which is dimensioned such that it detects the security feature of a document of value carried past the scanning line, even if the latter is arranged in a disordered manner on a carrier.
  • the security feature After excitation by the laser light, the security feature emits shorter-wave luminescent light according to the previously described effect, which is recorded by a photodetector and fed to the further evaluation as a raw luminescence signal.
  • the intensity profile of the emitted radiation in a specific wavelength range is analyzed over a predetermined measurement period after the excitation and a real-false statement is created.
  • the reading of security features of the aforementioned type is further improved.
  • At least one security element is inserted or applied in or on the value and / or security document, it being incorporated into a geometric pattern.
  • the security feature can be done using the well-known printing processes such as screen printing, intaglio printing, raster gravure offset, letter set, ink jet, etc. be printed on.
  • it can be applied as a transparent print below the visible motif if the material composition of the motif is such that it is suitable for the actual verification, i.e., for example, it is executed in a color that is sufficiently transparent for the excitation and luminescence wavelengths is.
  • the value and / or security document is scanned optically and excited with periodically pulsed electromagnetic radiation. It then emits luminescent radiation, from which raw signals are obtained. Both the scanning / excitation and the luminescence can take place in the entire electromagnetic wavelength range, but in particular in the invisible range and very particularly in the NIR range.
  • the sampled geometric pattern is extracted from the raw signals. The information encoded therein is output.
  • the security feature is no longer accidentally hidden in the motif or distributed over it, but is instead assigned to a geometric pattern in which information is encoded. Structural features and the information associated with them are thus extracted from the time-resolved intensity of the raw luminescence signal.
  • the present invention results in an advantageous extension of the conventional method because structural information is stored with the authenticity feature and, for example, nominal value or country coding can be read out with this additional information.
  • the invention also relates to a device for identifying the authenticity of security features on valuable and / or security documents, at least one security element being inserted or applied in or on the value and / or security document, and the security element being contained in a geometric pattern.
  • the device contains a scanning system with which the value and / or security document can be optically scanned.
  • the scanning system comprises a device for excitation of the security feature of the value and / or security document with periodically pulsed excitation radiation in order to receive raw luminescence signals from the security feature, and a device for extracting the scanned geometric pattern and the associated information from the raw luminescence signals.
  • the geometric pattern is designed as a bar code that can be read and decoded relatively easily and reliably, or if a pattern is selected that is invariant or star-shaped or completely rotationally symmetrical against rotation by 90 ° and 180 °, because that The measurement signal is then independent of the orientation of the disorderly applied stamp and the evaluation reliability is thereby considerably increased.
  • the scanning is preferably carried out in the form of a cell with a scanning line extending over the value and / or security document, along which the carrier of the value and / or security document is moved linearly at a constant speed.
  • the information encoded in the pattern is preferably the nominal value of the value and / or security document and / or its country coding, or the information that is most frequently used to identify the value document
  • the system according to the invention has a test device with which the raw luminescence signal can be checked according to wavelength and intensity profile, in particular for verifying the time constant. It also contains a decoding device for the geometric pattern extracted from the luminescence raw signal, in particular the bar code, and an output device for outputting a true / false statement and for outputting the information encoded in the geometric pattern.

  • Fig. 1 explains the basic principle.
  • the raw luminescence signal reflects characteristic geometric features.
  • the x ⁇ t ⁇ correlation can be seen clearly, i.e. With increasing x-expansion of the bar-like field, the signal becomes correspondingly wider. Conversely, the intensity increases according to the y extent of the marked field. The respective orientations therefore differ significantly from one another.
  • the top row contains printed samples which contain the security feature in the form of a luminescent substance.
  • the associated pattern of the raw luminescence signal is shown below, in which the printed geometry is reflected.
  • the sampling frequency is selected so that fine pixels are resolved down to the range of a few ⁇ m. If certain information is now assigned to the individual geometries, then nominal values, country codes, designations of origin can be derived differently.
  • samples such as those shown under D and E are particularly favorable because they deliver the same signals when rotated by 90 ° and facilitate the evaluation of appropriately glued-on value documents, labels or stamps.
  • Particularly suitable are star-shaped patterns that are invariant to even smaller angular rotations.
  • FIG. 3 shows further embodiments for printed motifs (upper row) and the associated raw luminescence signals.
  • Rotationally symmetrical patterns in the form of circular rings that also consist of can consist of several concentric rings with different widths and distances, are invariant to any rotation of the value document and thus significantly increase the evaluation reliability.
  • FIG. 1 A special embodiment is shown in FIG.
  • the feature (upper square) is applied in the form of a bar code. Since, according to the present invention, the spatial resolution is determined by the frequency of the excitation pulses, the line width can be designed such that thin lines are no longer resolved. The picture below shows that the raw luminescence signal no longer reproduces the thin line of the pattern. In this way, redundant non-information can be stored.
  • FIG. 5 shows a block diagram for a possible evaluation logic.
  • the wavelength and intensity profile for example in the form of a time constant, are checked from the luminescence raw signal generated with a specific pulse frequency. Depending on the agreement of these parameters with the given values, a genuinely false statement is made.
