Definitions
- the invention relates to a security arrangement for one of a plurality of similar security documents.
- the invention further relates to a security document having such a security arrangement and to a method for producing one of a plurality of similar security documents.
- documents of value such as banknotes, stocks, bonds, certificates, vouchers, checks, high-quality admission tickets, but also other counterfeit-endangered documents, such as passports or other identity documents, are usually provided with security elements that are difficult to falsify. their authenticity or integrity can be visually verified by a user with or without additional resources.
- Self-verifying banknotes of the kind disclosed in WO 98/15418 A1 also belong to this type of protection.
- 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 which contains a self-verification means for checking a security element arranged in a laterally spaced-apart area of the sheet.
- the self-verification is carried out by bringing the window area into register with the security element by bending or folding the sheet, and the security element and the self-verification means interact there suitably in order to confirm the authenticity of the banknote.
- Banknote does not know exactly, easily by some convincing effect effect in a forgery trick. Moreover, the security level of a self-verifying banknote is not significantly higher than that of an ordinary banknote, since the security element typically also forges the verification element and simulates a verifiable verification to the user.
- the object of the invention is to specify a safety arrangement which avoids the disadvantages of the prior art.
- the security arrangement should combine high counterfeit security with a high degree of recognition security even by laypersons.
- the security arrangement has an authenticity feature characteristic of the security document and at least one verification element for checking the authenticity features of others of the plurality of similar security documents.
- 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 safety arrangement arranged on another similar security document, thus precluding a self-certification. This measure ensures that the user has to pick up a second copy of the security document, for example a second similar banknote, during the authenticity check.
- the authenticity feature of a security arrangement is checked in a predetermined relative position of the authenticity feature and the verification element.
- the predetermined relative position can be, for example, a superimposition of authenticity feature and verification element with a specific spacing. This distance can be given for example by the focal length of a lens or the normal reading distance of a human. The preferred distance can also be zero, the authenticity feature and the verification element are then placed one upon another for testing. Some effects, such as the effect of crossed polarizing films, can be perceived by the preferred distance in a wide interval, and others, such as the magnifying power of a lens, can only be observed in a narrow range around the preferred distance.
- the authenticity feature and the verification element of the same security arrangement are geometrically arranged relative to one another such that they can not be brought into the predetermined relative position on the security document without damage.
- the authenticity feature and the verification element of the same security arrangement can be matched to one another in such a way that the authenticity feature and the verification element of the same security arrangement are in the predetermined The 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 of a security arrangement is checked by a predetermined relative movement of the authenticity feature and the verification element.
- the authenticity feature and the verification element of the same security arrangement can be geometrically arranged relative to one another such that the predetermined movement with them can not be carried out without damaging the security document.
- 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 do not exhibit the predetermined combination effect at the predetermined relative movement.
- the authenticity feature and / or the verification element are preferably transparent.
- transparency denotes the full transparency of a material with a certain gray density, with the objects behind the transparent material remaining recognizable in contrast to the translucency.
- the authenticity feature and the verification element are arranged in or above a common window area or hole of the security document.
- the authenticity feature and the verification element are arranged in close proximity to one another on the security document.
- the verification element comprises an optical imaging element for inspecting the authenticity features of other security arrangements arranged on similar security documents.
- the imaging optical element is in particular a magnifying lens such as a Fresnel magnifying lens or a Verzer ⁇ approximately lens. This may for example be a printed microprint auf ⁇ the authenticity feature made readable, or an optically distorted * '"* imprinted motif by the associated correction lens in the right shape.
- the authenticity feature contains an area printed with metameric colors. Metameric colors have different reflection spectra, but because of the sensitivity curves of the three color receptors, they appear to the human eye in the same hue with usual illumination with daylight. 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 veneering region.
- Rrealisedselement a second linearly polarizing window area.
- authenticity feature and / or verification element also comprise further polarizing regions. Due to the interaction of the different polarization directions when the different areas are brought together, a series of different type of authenticity tests can be performed 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 can 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 takes place 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 designed in the manner of a stereo eyeglass, wherein the authenticity feature of a safety arrangement when viewed binocularly by the two verification elements is one on another safety device.
- document applied security 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 verification elements of a security arrangement required for checking 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, it can be provided, for example, that the authenticity feature is folded together by this bending or folding process and thus becomes accessible. Alternatively, by means of this bending or folding process, an opaque cover layer can be automatically applied to the authenticity feature, which prevents subsequent verification.
- the verification element for the security document can also be formed in a characteristic manner, 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.
- both the authenticity feature and the verification element can be characteristic for the respective denomination of a banknote, so that banknotes of a particular denomination can only be verified with other banknotes of the same denomination.
- only the authenticity feature for the security document is designed in a characteristic manner, so that a check of the authenticity feature can be carried out with each verification element of a security arrangement arranged on another identical security document.
- a banknote series provision may be made for only the authenticity feature to be characteristic of the particular denomination of a banknote, but the verification element is identical in all banknotes of the series. Then, a banknote of a certain denomination can be verified with every other banknote of the same series, irrespective of their denomination.
- the invention also encompasses a security document, such as a security paper, value document or the like, having a security arrangement of the type described above.
- a security document such as a security paper, value document or the like, having a security arrangement of the type described above.
- the authenticity feature and the verification element are preferably geometrically arranged on the security document in such a way that they are not damaged without damaging the security document a predetermined relative position required for the authenticity check can be brought, or that a predetermined movement with them can not be carried out without damaging the security document.
- the security document may in particular be a security paper or a value document, such as a banknote, a check, an identity card, a customer or the like.
- the invention further comprises a method for producing one of a plurality of similar security documents, in which the security document is provided with a characteristic authenticity feature and at least one verification element for checking the authenticity features of others of the plurality of identical security documents, wherein a damage-free check of the authenticity feature a safety arrangement exclusively via a predetermined combination effect with a Ve-. Riqueselement can be performed ment arranged on another similargrodoku ⁇ ment security arrangement.
- the user Since the user is forced in the described security arrangement to use a second copy of the same for authentication, it combines high security against counterfeiting with high recognition security even by laymen who do not have the effect to be tested in memory. In addition, the authenticity check can be carried out easily and reliably by anyone without additional aids.

- FIG. 14 shows in (a) and (b) two variants for checking the authenticity of a banknote equipped with the security arrangement of FIG.
- FIG. 1 shows a schematic representation of a banknote 10 which is equipped with a security arrangement 14 according to the invention in a transparent window 12.
- the remote area 12 appears structurally normal. Only when a second, similar bill is picked up and the two banknotes are brought into a predetermined relative position, appears in the window a characteristic feature, such as a predetermined graphic motif or the denomination of the banknote.
- the security arrangement 20 has an authenticity feature 22 and a verification element 24, which are arranged directly next to one another in the window area 12 of the banknote 10.
- the authenticating feature 22 includes a first linearly polarizing region 26 in the shape of the numeral "5" having a first polarization direction, which in the embodiment is + 45 ° with respect to the centerline 36 of the security assembly 20.
- a second linearly polarizing region 28 surrounds the first region 26 and has a second polarization direction, which in the exemplary embodiment is 0.degree ..
- the circumferential line circumscribing the first linearly polarizing region 26 is merely added in the figure to the clearer representation of the two regions.
- the verification element 24 of the safety arrangement 20 contains a third linearly polarizing region 30 of the same shape and size as the first region 26 of the authenticity feature 22 and a fourth linearly polarizing region 32 surrounding the third region.
- the polarization direction of the third region 30 is perpendicular to the polarization direction of the first region 26, while the polarization direction of the fourth region 32 is parallel to the polarization direction of the second region 26.
- the four polarization regions 26 - 32 all have the same gray density.
- the four areas 26-32 of the security arrangement 20 give the observer the impression of a featureless, translucent, gray area under normal illumination conditions.
- Fig. 3 two similar banknotes 10-1 and 10-2 with security arrangements 20-1 and 20-2 superimposed so that the verification element 24-2 of the second banknote 10-2 on the authenticity feature 22-1 of the first bill 10-1, the numeral "5" clearly appears to the observer 34 due to the crossed directions of polarization of the two superimposed linearly polarizing portions 26 and 30.
- the appearance of the correct denomination at make-up ⁇ gen a further similar banknote can be evaluated by the user as a document for the authenticity of the banknote to be tested 10-1.
- the banknote 10-1 can also be used to authenticate the banknote 10-2, so that the two banknotes can mutually verify each other.
- Such a mutual verification leads to an increased level of security compared to self-verifying banknotes, since in the case of self-verifying banknotes in addition to the authenticity feature, the verification element can also be forged.
- the authenticity check therefore takes place with two bank notes.
- the user already owns one of them and checks with it a new one taken, e.g. Change at checkout. The probability that the already existing
- a self-authentication of the banknote 10, that is to say the use of the verification element 24 for checking the authenticity feature 22 of the same banknote, is not possible according to the invention without damaging the score. This is ensured in the exemplary embodiment by the choice of the polarization directions of the different linearly polarizing regions and the missing mirror symmetry of the coded digit "5.”
- the verification element 24 and the authenticity feature become 22 brought on top of each other, but the number ranges formed by the areas 26 and 30 are not congruent, but aligned mirror-inverted to each other.
- the polarization direction of one of the two linear polarizing regions 26 and 30 is mirrored when folding on the center line 36 and thus rotated by 90 ° so that the regions 26 and 30 after folding have the same direction of polarization. Therefore, even in their overlap region, there is no additional weakening of the transmitted light due to crossed polarizations, so that the encoded information can not be detected due to the lack of contrast difference to the surroundings 28, 32.
- the security arrangement 20 is formed in the window region with such high rigidity that it can not be folded about its center line 36 without damage. It is also possible to arrange authenticity feature and verification element with given rigidity so small and with such a small distance that they can not be placed on top of each other due to the minimum radius of curvature during folding. In both cases, authenticity feature 22 and verification element 24 of the same note can not be physically overlaid.
- FIGS. 4 (a) and (b) Another possibility for excluding the self-verification of a foreign-verifiable security arrangement 40 is illustrated in FIGS. 4 (a) and (b).
- the authenticity feature 42 and the verification element 44 in principle to the square shape as in Fig. 2 is formed.
- Aus ⁇ the authenticity feature 42 and the verification element 44, however, not only immediately adjacent to each other, but additionally arranged rotated by 90 ° from each other. This makes it impossible to place the verification element 44 in the correct orientation on the authenticity feature 42 of the same banknote without destroying the banknote.
- the second banknote 10-2 is turned through 90 ° for authenticity testing the first banknote 10-1 is laid, as shown in Fig. 4 (b).
- the digit areas of the verification element 44-2 of the second banknote 10-2 and the authenticity feature 42-1 of the first banknote 10-1 come to lie one above the other in the same orientation and the coded information can be read as described above.
- FIGS. 5 (a) and (b) show security arrangements 50 for banknotes with two different denominations ("5" and "10", respectively).
- the security arrangement 50 of FIG. 5 (a) contains an authenticity feature 52 and a verification element 54 directly next to one another.
- the authenticity feature 52 has a first linearly polarizing region 56 in the form of the number "5" with a first polarization direction of -67.5 °, refer to the centerline 62 of the safety arrangement, which linear polarizing region 58 is surrounded with a second polarization direction of + 22.5 °.
- the two linearly polarizing regions 56 and 58 have the same gray density when viewed in unpolarized light, so that the coded digit "5" can not be recognized under ordinary viewing conditions.
- the verification element 54 of the safety arrangement 50 contains a third linearly polarizing region 60 whose polarization direction corresponds to the polarization direction of the second region 58, that is to say + 22.5 °.
- the security arrangement 50 of FIG. 5 (b) for a banknote of another denomination is identical to the security arrangement 50 of FIG. 5 except for the shape of the first linearly polarizing area 56, which in this case forms the number sequence "10" (a) constructed.
- the polarization direction of the third region 60 acting as an analyzer and the polarization direction of the second region 58 are aligned parallel and thus translucent, while the polarization directions of the analyzer 60 and the first region 56 are perpendicular to one another and thus do not transmit light.
- the digit or sequence of digits of the underlying banknote thus emerges black in the transmitted light with a clear contrast against a gray background.
- the number "5" appears as the digit sequence "10”
- Analogous results are obtained for the other denominations of the banknote series.
- a self-verification of the safety arrangements 50 by folding about the center line 62 of the arrangements is not possible due to the selected polarization directions. If the verification element 54 of FIG. 5 (a) is folded onto the associated authenticity feature 52, then the polarization direction of the third linearly polarizing region 60 is mirrored at the center line 62 and now amounts to -22.5 ° after folding. as illustrated by the arrow 60 'indicating the direction of polarization of the folded third portion in Fig. 6 (b).
- the polarization directions of the first and second linearly polarizing regions 56 and 58 then respectively enclose the same angle (45 °) with the polarization direction of the folded third region 60 ', so that unpolarized light from the combination of the first region 56 and the folded third Area 60 'and the combination of the second area 58 and folded third area 60' is equally attenuated.
- the first and second areas 56 and 58 therefore have no contrast difference when viewed, the coded digit or Zif ⁇ telsequences of the authenticity feature 52 can not be perceived.
- the authenticity feature 72 and the verification element 74 of the security arrangement 70 are each broken down into a plurality of strips 76 or 78 of the same width arranged alternately.
- the coded information again the number "5" here for illustration, is essentially distributed over all strips 76 of the authenticity feature 72.
- the authenticity feature 72 and the verification element 74 can again have linearly polarizing subregions with different polarization directions for encoding, as described above.
- the security arrangement 70 is designed such that the digit or number sequence of the authenticity feature 72 is not recognizable under normal viewing conditions, but emerges only in cooperation with the verification element 74.
- the security arrangement 90 comprises an authenticity feature 92, which is introduced into a surface layer on the front side of a banknote 96, and a verification element 94, which is applied at a small distance from it, of a lenticular grid Cylindrical lens which is applied over a Novabe ⁇ rich or hole 98 of the banknote 96.
- Authentication feature 92 and verification element 94 are located near the center of banknote 96, thus that they can not be superimposed by rolling the banknote to a cylinder.
- the authenticity feature 92 contains a latent tilt image which is characteristic of the bank note and which can be represented by a lens raster in the manner of the verification element 94.
- the security arrangement 90 is designed for the foreign verification with banknote of different denomination of the same series, as explained in more detail with reference to the detailed representation of FIG.
- FIG. 9 shows two banknotes 96-1 and 96-2 which are stacked on top of one another such that the verification element 94-2 of the upper banknote 96-2 lies on the authenticity feature 92-1 of the lower banknote.
- the two banknotes are shown with a small gap.
- the authenticity feature 92-1 contains a latent tilt image that is characteristic of the banknote 96-1 and that can represent, for example, the denomination of the banknote from a first viewing direction 100 and a graphic motif from a second viewing direction 102.
- the lens raster 108 of the verification element 94-2 is designed identically in all banknotes of the banknote series, so that each banknote of the series can likewise be used for external verification.
- the lenticular grid 108 has a spacing d given essentially by the thickness of the banknote paper from the tilting image of the authenticity feature 92-1.
- the image information 104, 106 of the two images of the tilt image are, for example, with a pulsed infrared laser in a laser-sensitive Aufauf Drawing layer of the banknote 96-1 alternately inscribed or are suitably printed on the banknote paper with methods known in the art.
- the sequence of the image information 104, 106 is matched to the focusing effect of the lenticular grid 108 and the distance d during the authenticity check, that from the first viewing direction 100 only the image information 104 of the first motif and from the second viewing direction 102 only the image information v 106 of the second subject is visible.
- the authenticity feature 92-1 merely shows a confusing pattern in which the image information 104, 106 of the two inscribed motifs are mixed. Only by placing an adapted lenticular grid, a tilting image is created, which shows different motives from different viewing directions. Consequently, the image pattern 104, 106 of the authenticity feature is referred to as a "latent tilt image" alone.
- the appearance of the tilting image when placing the second note 96-2 offers the viewer the guarantee of the authenticity of the banknote 96-1 to be checked.
- the banknote 96-1 with its verification element can also be used to verify the banknote 96-2.
- a self-authentication of a banknote 96 is not possible according to the invention, since on the one hand the authenticity feature 92 and the verification element 94 can not be superimposed by rolling the banknote.
- a folding of the banknote 96 along the center line of the two elements does not lead to a representation of the tilting image since, depending on the folding direction, either the lenticular grid of the verification element 94 comes to rest headfirst on the authenticity feature 92, so that the cylindrical lenses display their focussed image.
- the distance between the image information 104, 106 and the lenticular grid is twice the interpretation distance d, so that the image information 104, 106 is not correctly distributed by the cylindrical lenses to the viewing directions 100, 102.
- the coded information is contained in the lenticular grid, which thus functions as an authenticity feature, while an imprint on the banknote forms the verification element.
- FIG. 10 shows a banknote 116 with a security arrangement 110 according to the invention, which displays an authenticity feature 112 applied over a window or hole 118 of the banknote in the form of a specially designed lens raster and a verification element 114 in the form of a printed label adapted to the lenticular grid Decoding area includes.
- the authenticity feature 112 is shown in greater detail in FIG. 11 (a), the verification element 114 in FIG. 11 (b).
- the authenticity feature 112 in the exemplary embodiment consists of an approximately 100 ⁇ m thick transparent PET film into which a surface relief in the form of a lenticular grid 120 is introduced.
- the raster elements 122 are formed by parallel straight cylindrical lenses which, for example, have a width of 50 ⁇ m and a spacing of 100 ⁇ m (raster period).
- a partial area 124 of the lenticular grid the grid elements 122 are offset by half a grid period, in other words by 50 ⁇ m in the exemplary embodiment, from their position outside the portion 124.
- the shape of subsection 124 represents the desired information, for example the denominator
- the outline shown in the figure serves merely to improve the visibility of the portion 124 and is not present in a real lenticular grid Under normal viewing conditions in transmitted light or reflected light hardly or not at all visible.
- the decoding area 126 contains in printed form a grid structure 128 which corresponds to the grid structure of the lens grid 120, but without the information-containing offset of the subarea 124.
- the information contained in the subregion 124 clearly appears when the lens raster 120 is placed on the decoding region 126.
- the observer sees only a certain section of the printed decoding area 126 due to the focusing effect of the cylindrical lenses 122.
- the observer sees outside the subarea 124 straight the black print lines 128 while looking within the portion 124 on the white space between adjacent print lines 128.
- the information in this case the number "5", thus appears white on a black background
- the safety arrangements each contain two verification elements which must cooperate in order to test the authenticity feature. Also in this way it can be ensured that only a foreign but not a self-certification of banknotes can take place.
- FIG. 12 shows a banknote 130 which is provided with a security arrangement 132 comprising an authenticity feature 134, a first verification element 136 and a second verification element 138.
- the two verification elements 136 and 138 are arranged at eye relief on the banknote and designed in the manner of a stereo goggle, for example a red-green stereo goggle, or a polarization stereo goggle.
- a stereo goggle for example a red-green stereo goggle, or a polarization stereo goggle.
- the verification elements 136 and 138 consist, for example, of red or green filter foils embedded in the banknote paper.
- the authenticity feature 134 arranged between the two verification elements 136, 138 in this case contains an image motif which is printed on a light background with red and green color.
- the two colored partial images show the image motif from two different viewing angles, so that when the partial images are guided through the corresponding filter film to the eye, a three-dimensional plastic image effect is produced in the viewer.
- banknote 130 can now not be brought into a position without damage, in which its authenticity feature 134 can be viewed through the two verification elements 136 and 138; rather, a second similar banknote is always required for the authenticity check. If all banknotes of a series are equipped with such security arrangements 132, wherein only the authenticity features 134 differ depending on the denomination, each banknote of the series can be used to authenticate other banknotes of the series.
- the two verification elements 136 and 138 can also form a polarization stereo-ghost by being formed from two polarization films oriented perpendicular to one another in a window region or hole of the banknote.
- the authenticity feature 134 arranged between the verification elements 136, 138 contains two polarizing partial images which are matched to the polarization angles of the polarization films and which can be printed, for example, with the aid of dyes containing liquid crystal pigments.
- FIG. 13 shows a further exemplary embodiment of the invention, in which the two verification elements 146 and 148 of the security element 142 have to be switched one behind the other in order to be able to check the authenticity feature 144.
- the authenticating feature 144 is a liquid crystal layer containing a suitably-introduced characteristic motif.
- the liquid crystal layer includes a first portion 152 which selectively reflects right circular polarized light, and a second portion 154 which selectively re-inflects left circularly polarized light with the same color reflection spectrum.
- the different circular polarization of the light reflected by the authenticating feature 144 can not be perceived, the feature appears as a featureless color area.
- the first verification element 146 of the security arrangement 142 consists of a ⁇ / 4 layer adapted to the color reflection spectrum of the liquid crystal layer of the authenticity feature 144, the second verification element 148 of a suitably oriented, linearly polarizing layer.
- the two verification elements 146 and 148 must be placed in the correct order over the authenticity feature 144, as explained in more detail below with reference to FIGS. 14 (a) and 14 (b) ,
- the two verification elements 146 and 148 are arranged directly next to one another on the banknote 140, so that they can be placed 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 so 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 in the case of correctly superimposed verification elements.
- 14 (a) shows a first variant of the authenticity check of a banknote 140-1 provided with the security arrangement 142-1.
- 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 selectively circularly polarized light.
- the ⁇ / 4 layer of the first Veriss ⁇ element 146 converts this circularly polarized light in linearly polarized light with mutually perpendicular polarization directions.
- the subsequent linear polarizing layer of the second verification element 148 is oriented in such a way that it transmits the light originating from the second subregion 154 and blocks the light originating from the first subregion 152.
- the motif in the embodiment example, the number "5" then appears black against a light background.
- the authenticity check can also be carried out with three similar banknotes, as shown in FIG. 14 (b). 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 superimposed in this order. In this configuration, the information of the authentication feature 144-1 can be read out as described above.
