Definitions

  • the present invention is in the technical field of the production and checking of documents of value and relates to a document of value with a security marking and a method for identifying the same.
  • the pamphlet US 7762468 B2 shows an authentication method in which a combination of two luminescent substances with different decay times is used. In this process, the second, slower decaying luminescent substance detected only when the luminescence of the first luminescent substance has already decayed.
  • the pamphlet US 9046486 B2 discloses a security marking and a method for identifying the same based on combinations of quasi-resonant luminescent substances with a different exponential decay behavior. With the help of a non-linear adaptation, both the amplitudes and the decay times are determined. The method described is not suitable for marking substances with a strongly non-exponential decay behavior, which limits the number of marking substances available. The analysis by means of non-linear adaptation also proves to be time-consuming and error-prone with regard to noise, so that the speed and quality of the evaluation are low.
  • the US 2014/0001351 A1 discloses two luminescent materials intermingled in a security feature.
  • the object of the present invention is to enable reliable, secure and rapid identification of the identification of a document of value with luminescent substances with complex time behavior.
  • a document of value with a security marking is shown.
  • value document means any objects to be protected against undesired or illegal copying, for example banknotes, checks, shares, tokens, ID cards, credit cards and passports as well as labels, seals, packaging or other objects for value protection.
  • the security marking of the value document according to the invention can be assigned to at least one freely definable (binary) property of the value document, the property being given in the event of identification (presence of the security marking) and in the case of non-identification (absence the safety marking) is not given.
  • the security marking can be assigned to the property “authenticity” as an authenticity marking or authenticity feature in order to recognize value documents as either authentic or forged. It is also conceivable that the security marking assigns value documents, for example, to a specific class or group, such as the note value or country of manufacture of bank notes.
  • the security marking is designed in the form of at least two luminescent substances (hereinafter also referred to as luminescent substances).
  • the luminescent substances can be incorporated into the value document or attached to the value document in the most varied of ways.
  • the luminescent substances can be mixed into a paper or plastic mass for producing the document of value or a printing ink for printing the document of value. It is also conceivable to provide the luminescent substances as, for example, an invisible coating on the document of value.
  • the luminescent substances can also be provided on or in a carrier material consisting, for example, of plastic, which is embedded in a paper or plastic compound for producing the document of value.
  • the carrier material can be designed, for example, in the form of a security or identification thread, a mottled fiber or planchette.
  • the carrier material can also be attached to the value document, for example in the form of a badge, for example in order to undertake a product security measure. In principle, any desired shape of the carrier material is possible.
  • the at least two luminescent substances of the security marking can be excited jointly by a (same) excitation pulse (eg light flash). It is essential here that the time courses of the intensities of the emitted radiations of the luminescent substances excited by the excitation pulse differ from one another are, wherein at least one luminescent substance has a non-mono-exponential time course of the intensity of the emitted radiation.
  • a excitation pulse eg light flash
  • the security marking contains the at least two luminescent substances in a definable or defined quantity ratio in combination (preferably in the form of a mixture). This means that each luminescent substance is present in the security marking in a definable or defined, relative proportion, based on the total amount of luminescent substances.
  • the security marking can thus be clearly identified on the basis of the quantitative ratio (mixing ratio) of the luminescent substances.
  • each luminescent substance contributes with the intensity of its emitted luminescent radiation to the total intensity of the simultaneously emitted radiations of the excited luminescent substances of the security marking.
  • total intensity refers here and in the following to a summary intensity of the luminescence radiation of the luminescent substances contained in combination in the security marking, excited by a (same) excitation pulse and detected at the same point in time.
  • the security marking is designed so that, for identification of the security marking, the quantity ratio (mixing ratio) of the luminescent substances is determined by analyzing the time course of the total intensity of the emitted luminescence radiation (excited by an excitation pulse) on the basis of the time progression of the intensities of the luminescence radiation (excited by the same excitation pulse) the luminescent substances can be determined.
  • the use of at least one luminescent substance with a non-mono-exponential has the particular advantage that a large number of substances that are suitable in principle are available and that, through the specific selection, improved security against forgery can be achieved. In addition, a relatively large difference in the clinking and / or decay behavior of the luminescent substances can be achieved, which allows reliable and secure identification of the security marking. If the excitation light is re-emitted with an (anti-) Stokes shifted wavelength due to intrinsic conversion processes, a clear separation of the excitation and emission radiation is easily possible by means of suitable filter techniques.
  • the at least two luminescent substances are particularly advantageously selected so that the intensity of the emitted radiation of each luminescent substance is in a range from 5% to 95%, preferably 10% to 90%, and particularly preferably 15% to 85%, of the total intensity of the luminescent substances. This enables a particularly precise analysis of the time course of the total intensity of the security marking on the basis of the time course of the intensities of the luminescent radiation emitted by the respective luminescent substances, which contributes to improving the reliability of the identification of the security feature.
  • the at least two luminescent substances are preferably selected so that the decay time, ie in particular the time between the end of the excitation pulse and the reaching of an intensity of 1 / e of the intensity at the end of the excitation pulse, is in a range from 100 ns to 100 ms, preferably 10 ⁇ s to 5 ms.
  • This is advantageous for a precise analysis of the time course of the total intensity of the emitted luminescent radiation of the luminescent substances on the basis of the time course of the intensities of the luminescent radiation emitted by the respective luminescent substances, which further improves the reliability of the identification of the security feature.
  • the at least two luminescent substances have overlapping, in particular identical, excitation spectra, which enables targeted and relatively strong excitation of the luminescent substances by a comparatively narrow-band excitation pulse (flash of light).
  • the at least two luminescent substances particularly preferably have overlapping emission spectra, as a result of which the security against forgery of the security feature is advantageously further improved due to a significantly more difficult analysis of the emitted radiation.
  • the at least two luminescent substances are designed such that the time courses of the intensities of the emitted radiation over a Bray-Curtis distance of greater than 0.10, preferably greater than 0.20, and particularly preferably greater than 0.25.
  • This measure can also increase the accuracy of the analysis of the time course of the total intensity of the emitted luminescent radiation of the luminescent substances of the security marking on the basis of the time course of the intensities of the luminescent radiation emitted by the luminescent substances, which contributes to an even further improvement in the reliability of the identification of the security feature.
  • the luminescent substances of the security marking of the document of value according to the invention can in principle be freely selected as long as it is ensured that they can be excited together by an excitation pulse and the time courses of the emitted radiations of the luminescent Substances are different from one another, at least one luminescent substance having a non-mono-exponential time course of the intensity of the emitted radiation.
  • the excitation and emission of the luminescent substances can take place in the UV, VIS and / or IR range.
  • luminescent substances can be used which are excited in the UV range and emit in the UV range or visible spectral range.
  • luminescent substances can be used which are excited in the IR range and emit in the IR range or emit in the visible range (up converters).
  • luminescent substances are advantageous which show a particularly strong non-monoexponential decay behavior after excitation.
  • luminescent substances which each comprise a host lattice which is doped with at least one dopant selected from the rare earth metals and transition metals (or their ions).
  • Suitable inorganic host lattices are, for example, oxides, borates, gallates, phosphates, garnets, perovskites, sulfides, oxysulfides, apatites, vanadates, tungstates, glasses, tantalates, niobates, halides, oxyhalides, in particular fluorides, silicates or aluminates.
  • Host lattices such as YAG, ZnS, YGG, YAM, YAP, AlPO 5 , Zeolite, Zn 2 SiO 4 , YVO 4 , CaSiO 3 , KMgF 3 , Y 2 O 2 S, La 2 O 2 S, Ba 2 can be used as the host lattice P 2 O 7 , Gd 2 O 2 S, NaYW 2 O 6 , SrMoO 4 , MgF 2 , MgO, CaF 2 , Y 3 Ga 5 O 12 , KY (WO 4 ) 2 , SrAl 12 O 19 , ZBLAN, LiYF 4 , YPO 4 , GdBO 3 , BaSi 2 O 5 or SrBeO 7 can be used.

  • Luminescent substances with a strongly non-mono-exponential time behavior of the intensity of the emitted radiation can be implemented by different mechanisms.
  • energy transfer processes between different doping ions, in particular rare earth doping ions intrinsically multiple time constants can occur in the attack and decay behavior.
  • Such energy transfer processes are, for example, for the doping ion combinations Yb / Er, Nd / Yb, Yb / Tm, Cr / Tm, Tm / Ho, Er / Tm, Er / Ho, Yb / Ho, Cr / Ho, Fe / Tm, Mn / Tm , Cr / Er, Fe / Er, Cr / Nd, Cr / Nd, Cr / Yb, in particular in combination with other doping ions, are known. According to the invention, the use of such doping ion combinations is preferred.
  • luminescent substances with complex intrinsic energy transfer processes can show intensity profiles with strongly non-mono-exponential time behavior, wherein the luminescence intensity can increase even further after the end of the excitation phase.
  • the combination of such substances together with classical substances, which show a monotonously decreasing behavior after excitation allows a targeted adjustment of the time behavior of the total intensity of the luminescent substances. In addition to falling emission sections, this can also have rises, plateaus, local maxima and / or minima.
  • the security marking has a combination of at least one luminescent substance with non-monoexponential time behavior and at least one luminescent substance with monoexponential time behavior of the intensity of the emitted luminescence radiation.
  • the security marking can have a combination of at least two luminescent substances, each with a different, non-mono-exponential time behavior of the intensity of the emitted luminescent radiation.
  • luminescent substances in which several different transitions of a doping ion, which are very similar in terms of energy but have different lifetimes, contribute to the emission in a narrow wavelength range. These luminescent substances also often show non-mono-exponential time behavior. Examples are Pr and Er.
  • luminescent substances can exhibit non-mono-exponential behavior due to inhomogeneities which occur randomly or which are specifically generated during production, for example an inhomogeneous grain size distribution or an inhomogeneous distribution of the dopants. This can occur, for example, when grains with a faster time behavior, ie a faster decay time and / or a faster rise time, as well as grains with a slower time response, ie a slower decay time and / or a slower rise time, arise.
  • Their different properties are averaged in the relevant, macroscopic measurement, in which a relatively large number of individual grains are generally excited and measured at the same time. This overlap the individual time structures of the emissions of the individual grains in such a way that overall a non-mono-exponential time behavior can result.

  • the security marking is thus clearly identified (ie is present), since the ratio M 1 , M 2 has been assigned the attribute “ratio accepted” and the quality of the adaptation is above the desired threshold value. Due to the need for both conditions to be present (attribute ratio, quality of adaptation), a particularly high level of reliability can be achieved in the identification of the security marking.
  • the mixing proportions of the luminescent substances A, B, C, in this order are 20%, 50%, 30%, in each case based on the total amount of luminescent substances.
  • the mixing ratio A / B / C is therefore 20% / 50% / 30%.
  • the combined intensity behavior was measured with a signal-to-noise ratio of approx. 20.
  • the measurement data are in Fig. 4 shown. Following this, the above-mentioned linear combination of the general formula A with three basis vectors I A (t), I B (t), I C (t), as shown in Fig. 3 are adjusted, the linear coefficients c 1 , c 2 c 3 being determined by the least squares method.
  • an elliptically shaped tolerance range for example, is defined in an ab plane (see FIG Fig. 5 ). Due to the shape of the temporal intensity behavior, this can be differently extended in different directions.
  • the measured mixture tuple is represented by the filled circle, the target value (previously known mixture tuple) by the empty circle.
  • the attribute “ratio accepted” is assigned if the ratio lies within the associated value range, or the attribute “ratio not accepted” if the ratio lies outside the associated value range.
  • the two ratios M 1 , M 2 are within the associated value ranges W 1 , W 2 , the correct, ie previously known, relative mixing proportions of the two luminescent substances A, B, each based on the total amount of luminescent substances A, B, C were determined.
  • the security marking has the previously known composition, with which the security marking was identified.
  • Fig. 6 upper figure, taken.
  • noise components with different normal distribution were added to the measurement points in a decay curve of a mixture of two luminescent substances with mono-exponential decay behavior.
  • An evaluation was carried out using a linear adaptation method according to the present invention and a non-linear adaptation method known in the prior art.
  • Fig. 6 lower figure, the evaluation is illustrated in a diagram in which the relative mixing proportion of a luminescent substance is plotted against the noise level. It can be seen that the determination of the relative mixing proportion according to the invention shows a lower susceptibility to noise compared to the method known in the prior art.
  • Fig. 7 shows the time behavior of a mono-exponentially decaying luminescent substance that could be used, for example, for a counterfeit attack.
  • Fig. 8 shows a value document 1 in the form of a bank note, for example, which has an identification thread 2 with a security marking 3.
  • the security marking 3 can be designed as described above.
  • the invention offers great advantages over the evaluation methods known in the prior art with non-linear adaptation in which, in addition to the amplitudes of the temporal intensity spectra, the decay times are also used as model parameters.
  • a much faster and more stable evaluation ie faster convergence behavior of the adaptation routine
  • predetermined time behavior in particular decay curves
  • a quantitative evaluation results in a computing time reduced by approx. 3 orders of magnitude compared to the non-linear adaptation known in the prior art, which increases the efficiency with regard to the evaluation speed clarified.
  • a fast evaluation method is essential, for example for the analysis on fast-running banknote processing machines with bank notes moving up to 12 m / s, since these essentially determine the processing speed.
