Description

[Field of the Invention]
The present invention provides: Concerning confidential and / or valuable documents. This confidential and / or valuable document has a confidential element, which is from “hologram, laser engraving, printing motif, fluorescent motif, luminescent motif, diffraction motif and optical change ink (OVI) motif”. Having at least two different security features selected from the group consisting of The invention relates to a method for producing such a confidential and / or valuable document and to a method for authenticating such a confidential and / or valuable document.

[Background and prior art]
Confidential elements are used to protect confidential and / or valuable documents from forgery or copying. Typically, confidential and / or valuable documents have a plurality of different confidential elements and are only validated if all confidential elements are present.

      A previously known type of security feature is a braided pattern manufactured in a printing technique. This braided pattern is a very delicate line pattern, which cannot be manufactured without costly printing technique.

      Another type of security feature is produced by laser engraving. To this end, confidential and / or valuable documents have a confidential feature layer that absorbs the wavelength light of the laser. Here, in absorbing the laser beam, the energy converted into heat causes the visible material to break and / or discolor. Here, the laser beam can be run from end to end of the security feature layer, for example, by a mirror image structure, thereby forming lines, patterns, and surfaces. Laser engraving may in this case take place in a security feature layer that is covered by an additional layer, but is only possible if this additional layer does not absorb or absorbs much of the laser beam.

      A further type of sensitive feature is a hologram. The production of a volume hologram is described in Patent Document 1, for example. Embossed holograms image a holographic structure onto a matrix, for example by a photographic process, followed by a chemical process on the matrix to form the holographic structure as a topography, and the matrix is formed, for example, in a plastic layer Used to transfer the holographic topography onto the plastic layer by the action of pressure and / or temperature.

      A further type of sensitive feature is a fluorescent motif. In this case, the graphic structure is made of a material capable of emitting light (trend or phosphorescence). When excited by light, for example UV light, the material emits light and the motif becomes visible (if it is not visible without irradiation), or (if it is visible with ink etc. without irradiation) ) You can see that it emits light.

      In practice, for example in the case of a 50 euro bill, the confidential element is known. Here, different layers have multiple confidential features. These confidential features are registered and positioned one above the other, and the graphic structures of these confidential features are connected to each other. Here, when the transmitted light is applied, “50” of money can be seen in the upper left of the surface. On the other hand, with incident light, only the mutually complementary portions of “50” are visible on both sides. Here, the two confidential features are produced by a similar technology, ie by printing technology.

      For example, Patent Document 2 discloses a confidential and / or valuable document of the format described at the beginning. Here, various techniques such as hologram and laser engraving are combined with each other within the range of confidential features. For example, separate symbol strings are written into the hologram by laser engraving. Here, the two confidential features are usually in the same layer, usually depicting graphic structures that are independent of each other.

      Confidential and / or valuable documents known so far cannot be copied without increasing technical costs.

[Technical Problem of the Invention]
The technical problem of the present invention is to present confidential and / or valuable documents that require little or very little cost.

[Definition]
The concept of different secret features is a secret feature produced by different technologies. For example, all printing techniques for non-fluorescent inks are considered as one technique in this case. All technologies for fluorescent inks are also one technology (unlike all printing technologies for non-fluorescent inks). The same applies to all holographic techniques. Different confidential features are, for example, the following combinations: hologram / print motif, hologram / fluorescence motif, hologram / laser engraving, print motif / laser engraving, print motif / fluorescence motif, or laser engraving / fluorescence motif. By definition, the same applies to three different confidential features, in this case for example the following combinations: hologram / print motif / laser engraving, hologram / print motif / fluorescence motif or print Motif / Laser engraving / Fluorescent motif. In the case of four different security features, for example, a combination of hologram / print motif / laser engraving / fluorescence motif.

      The confidential element is formed from a plurality of confidential features.

      The graphic structure means, for example, a line, a symbol or a surface pattern or a part thereof. In the case of a line, it is a line having a line width in the range of 0.001 mm to 1 mm, and preferably in the range of 0.01 mm to 0.02 mm. The symbol can be, for example, an alphanumeric character, for example a number or an alphabet. The surface pattern is basically a surface-like structure as a whole, and has a defined shape, for example, a circle, a rectangle, a square, an ellipse, an arc segment, an annular shape, an annular segment, or the like.

      In this case, if the graphic structure is a graphic structure in which different confidential elements are combined with each other to form one overall representation, the overall graphical representation is formed. Thus, different sensitive elements can be complementary. For example, the first confidential element forms a first partial line and the second confidential element forms a second partial line, where the two partial lines are in a complementary relationship to each other. Therefore, a single line is formed as a whole. This can be set, for example, in the case of a line pattern, such as a braid decoration pattern. In that case, the first secret element forms a first part of the line pattern and the second secret element forms a second part of the line pattern. Another example is complementary sub-symbols for different confidential elements, which combine to form a single symbol, such as an alphabet or number. In these cases, the graphic structures are connected to each other. In this case, of course, there may be at least partial overlap, and there may be gaps between the graphic structures that are not immediately apparent to the human eye. Eventually, the entire graphic representation becomes a surface underlay of the line pattern or symbol. In this case, different confidential features overlap each other.

      The whole graphic representation is a predetermined graphic representation. This arises as a whole from the graphic structure of the different sensitive features. The overall graphic representation forms a confidential element.

      The main feature of the overall graphic representation is the lack of one or more graphic structures, resulting in an incomplete representation, whether it is human-readable or machine-readable. The structure or its defect is directly noticeable or detectable. In particular, in the case of a whole graphic representation, information such as symbol strings, images, etc. If one graphic structure is missing, the information is clearly incomplete and can be easily reconstructed completely. Can not.

      A confidential element is a structural unit having at least one confidential feature. The confidential element can be a self-supporting structural unit. This unit can be associated with confidential and / or valuable documents, for example by gluing. Alternatively, this unit may be a component integral with confidential and / or valuable documents. An example of the former case is a holographic label, for example. An example of the latter case is a layer with confidentiality features integrated within the layer structure of confidential and / or valuable documents.

      Confidential and / or valuable documents are typically composed of a planar substrate. At least one layer, for example, a printing layer is formed on one side or both sides of the substrate. As the material for the substrate, materials known in the paper and / or plastics technical field can be used. The substrate is not necessarily composed of only one layer, and may be composed of a plurality of layers, for example, a film (laser irradiable, laser unirradiable, opaque, chip inlay, etc.). It may be transparent or light transmissive, and may have a transparent or light transmissive window. In the case of a multi-layer substrate, layers of different substrates can be combined with each other at once, for example in a single lamination step, as combined with a layer applied on the substrate in the manner as in the present invention. .

      Graphic structures or whole graphic representations are individualized if they differ for different confidential and / or valuable documents of the same type. In that case, sub-groups may be formed for the same type of confidential and / or valuable documents. In that case, these confidential and / or valuable documents will have the same graphic structure or overall graphic representation but differ only in subgroups. Examples of such graphic structure or overall graphic representation are the name of the confidential and / or valuable document owner, the serial number of the confidential and / or valuable document, the representation of the address of the confidential and / or valuable document owner, etc. is there.

      Graphic structures or entire graphic representations are not individualized or static if they are the same for the same type of confidential and / or valuable documents. Examples of such cases are emblems, seals, national emblems, braid patterns, currency displays, nationality displays, and the like.

      The graphic structure or the entire graphic representation can be either machine-recognizable or machine-readable or machine-recognizable, or machine-readable and visible. An example of the former case is a barcode. An example of the latter case is an alphanumeric string.

      If graphic structures of different confidential features provided in different layers generate a predetermined overall representation, the two layers of confidential and / or valuable documents are registered and overlapped with each other.

[Basic features and official embodiments of the invention]
In order to solve the above technical problem, the present invention provides that each confidential feature has one graphic structure, and the graphic structures of different confidential features may be graphically adjacent to each other or confidential and / or valuable documents. In different layers or in the same layer, or in different layers of confidential and / or valuable documents. ing.

      In this case, there are various configuration possibilities. For example, the graphic structure of different sensitive features may be lines, and the ends of the lines of different sensitive features are connected to each other, or preferably extend parallel to each other and overlap. . Examples in this case are lines of line patterns, such as braid decorations, alphanumeric lines. The graphic structure of the first confidential feature may have a planar structure, and the graphic structure of the second confidential feature has a line, and the graphic of the first confidential feature and the second confidential feature. The structures overlap each other. An example in this case is a braided pattern or an alphanumeric line pattern, for example, which is laid under a flat surface.

      A confidential and / or valuable document may have multiple confidential feature layers, with different confidential features being provided in different confidential feature layers. In this case, different security features may be provided in different security feature layers immediately adjacent or in different security feature layers separated by at least one intermediate layer.

      A preferred embodiment according to the present invention is characterized in that the first confidentiality feature is a laser engraving or printing motif and the second confidentiality feature is a hologram.

      Also preferably, the confidential and / or valuable document has the following layer structure: substrate, first intermediate layer selectively provided on the main surface of the substrate, main surface of the substrate, or uppermost intermediate layer A first secret feature layer having a first secret feature, a second intermediate layer selectively provided on the secret feature layer having a first secret feature, and a first secret feature layer Or a second security feature layer having a second security feature and a selective cover layer provided on the second intermediate layer. In this case, the further layer provided above the first sensitive feature layer is in any case transparent in the area covering the graphic structure of the first sensitive feature from end to end. I understand.

      In the present invention, the confidential element or the entire graphic representation is recognizable by incident light and / or transmitted light. In the former case, it can be treated with an opaque substrate. If the confidential element is (as well) recognizable by transmitted light, the substrate is transparent or translucent below the confidential element, or transparent or semi-transparent under the confidential element. It has a transparent window. If the substrate is transparent or translucent or has such a window, unlike the layer structure described above, the optional second intermediate layer, the second security feature layer and possibly the second The cover layer may be provided on the main surface of the substrate facing the first confidential feature layer.

      Within the scope of the present invention, the first intermediate layer and / or the second intermediate layer and / or the cover layer may consist of a plurality of partial layers.

      A preferred variant according to the invention is characterized in that the first security feature is a laser engraving or printing motif and the second security feature is a hologram. In this case, the hologram may be selected from the group consisting of “volume hologram, embossed hologram, transparent kinegram overlay, kinegram and zero order grating”. The print motif can be a line pattern, in particular a braided decoration, alphanumeric characters or parts thereof.

      Confidential and / or valuable documents include ID cards, passports, entry / exit permits, visas, control symbols, tickets, driver's licenses, car certificates, banknotes, checks, postage stamps, credit cards, chip cards and adhesive labels. Take as an example.

      The invention relates to a method for producing confidential and / or valuable documents according to the invention. The method comprises the following steps: a) the substrate is selectively coated with an intermediate layer, b) the substrate or the first intermediate layer is provided with a first sensitive feature layer, c) the first A second intermediate layer is selectively applied to the intermediate layer or the first confidential feature layer, and d) the second confidential feature layer is applied to the first confidential feature layer or the second intermediate layer. E) the second sensitive feature layer is optionally provided with a cover layer, and steps a) to e) can be performed simultaneously or before and after each other, The first sensitive feature is already present in the first sensitive feature layer in step b), or is incorporated in the first sensitive feature layer following step d) or e), and / or Or whether the second sensitive feature already exists in the second sensitive feature layer in step d), or , Following the step d) or e), incorporated in the second confidential feature layer. In this case, for example, laser engraving is used when incorporating confidential features after step d) or e). In that case, it can be seen that the layer on which the layers having laser engraving are stacked has transparency to the laser beam.

      It should be mentioned that in the method according to the invention it is important that the different steps of applying the layers and their combinations can be carried out at the same time, for example during lamination to the substrate. Of course, it is also possible to apply the layers next and connect the layers.

      The implementation of the method according to the invention may differ in individual points.

      The first sensitive feature may already exist in the first sensitive feature layer in step b) and the second sensitive feature may already exist in the second sensitive feature layer in step d). The second confidential feature layer is then applied in registration with the first confidential feature layer in step d). This also means that, prior to step d), the position and orientation of the first confidential feature of the confidential and / or valuable document is determined by the optical detection means, which optical detection means Connected to a controller for layer positioning, which is controlled by being controlled in step d) so that the positioning of the second security feature layer takes place in registration. It may be broken. The optical detection means can be, for example, a CCD camera. The control device detects the position and direction of the first confidential feature with respect to the CCD camera or its graphic structure based on the signal of the CCD camera, and controls the control device, for example, the robot arm by the coordinate signal.

      However, the first confidential feature is not applied to the first confidential feature layer in step b), and the second confidential feature is applied to the second confidential feature layer in step d). Also good. In this case, following step d) or e), the first security feature is incorporated in registration with the first security feature layer, for example by laser engraving. This is, following step d), first the position and direction of the second confidential feature on the confidential and / or valuable document is determined by the optical detection means, which incorporates the first confidential feature. Connected to a control device for controlling the means for, after which the control device is controlled so that the incorporation of the first sensitive feature into the first sensitive feature layer takes place in register. May be performed by: When performing laser engraving to incorporate the first security feature, the control device has, for example, a mirror system that can be swiveled in two dimensions. This mirror system allows the laser beam to be arbitrarily positioned within the first confidential feature layer. On the other hand, the second confidential feature may not be applied to the second confidential feature layer in step d), and the first confidential feature may be applied to the first confidential feature layer in step b). . In that case, following step d) or e), the second secret feature is incorporated in registration with the second secret feature layer (5). Thereafter, the same as described above is performed.

The present invention relates to a method for authenticating confidential and / or valuable documents. In this way,
First, the presence of both the first secret feature and the second secret feature is verified, and if the verification confirms the presence, the first secret feature and the second secret are registered with each other and positioned. If it is verified that it is registered and registered and positioned, the confidential and / or valuable document is classified as valid. In the simplest case, verification is performed by visual recognition with human eyes. Thus, for example, in the case of counterfeiting because the two confidential feature layers are not registered, the lines of the line pattern will have steps, gaps or folds. Of course, this verification can also be performed by mechanical means such as a camera. In this case, the measured pattern is compared with a predetermined pattern stored by the processor. If the results of the two verifications described above are negative, the confidential and / or valuable document is rejected as invalid.

      Within the scope of the present invention, the first confidentiality feature and the second confidentiality feature may be individualized or static. Similarly, the first secret feature may be personalized and the second secret feature may be static and vice versa.

      Hereinafter, the present invention will be described in detail with reference to the drawings showing only examples.

It is sectional drawing which shows the layer structure of the confidential and / or valuable document of this invention which concerns on a 1st modification. It is sectional drawing which shows the layer structure of the confidential and / or valuable document of this invention which concerns on a 2nd modification. FIG. 3 is a top view of a confidential and / or valuable document according to the present invention. FIG. 4 is a top view showing only the second confidential feature layer of the subject according to FIG. 3. FIG. 4 is a top view showing only the first confidential feature layer of the subject according to FIG. 3. 1 is a schematic diagram of an apparatus for accurately registering or incorporating a graphic structure. FIG.

  FIG. 1 shows a confidential and / or valuable document with a substrate 2. On the substrate 2, a first intermediate layer 3, a first secret feature layer 4, a second secret feature layer 5 and a cover layer 6 are applied. The first confidential feature layer 4 has a first graphic structure 7 as a confidential feature. This first graphic structure is generated by laser engraving. The third confidential feature layer 5 has a second graphic structure 8 as a confidential feature. The second graphic structure is configured as a hologram, for example. In this case, the production can be performed as follows. That is, after the illustrated series of layers is first created, the first graphic structure 7 is incorporated into the first sensitive feature layer by a laser. For this purpose, first the second graphic structure 8 is detected under specific illumination, for example using a light source and a camera. The position of the second graphic structure 8 detected in this way is used to control the laser, whereby the first graphic structure 7 is registered with respect to the second graphic structure 8. In the state, it is incorporated into the first secret feature layer.

      A variant is shown in FIG. In the figure, a first confidential feature layer 4 having a laser engraving (or printing motif) is provided directly on the substrate 2. This is optionally followed by a second intermediate layer 9. On top of that, a second confidential feature layer 5 having a hologram is provided. Manufacture can be performed as follows. The first graphic structure 7 is applied at the same time as the first sensitive feature layer 4 (as a print motif) or immediately after (as a laser engraving). Thereafter, optionally, the position and orientation of the large graphic structure 7 may be optically detected. Then, the second confidential feature layer 5 having a hologram is applied by registration, for example, by gluing.

      Comparing FIG. 3 to FIG. 5, it can be seen that the first confidential feature layer 4 and the second confidential feature layer 5 are registered and stacked. In particular, it can be seen that the lines of the first graphic structure 7 and the lines of the second graphic structure 8 are accurately connected. The figure also shows a third graphic structure 10 and a fourth graphic structure 11. Here, the third graphic structure is a character string arranged in a circle, the fourth graphic structure is an arc surface, and the circular width of the arc surface is centered in the longitudinal direction of the character string. , At least corresponding to the height of this string. The graphic structures 7, 8, 10, 11 are each configured with a confidential element 12.

      In either case, the first sensitive feature layer 4 and the second sensitive feature layer 5 are registered because the line is interrupted or broken, or the string is not centered on the annular surface. If it does not overlap in the state, it can be immediately identified with the human eye. Thus, counterfeiting can be easily identified and rejected. On the other hand, authentic confidential and / or valuable documents can be readily determined and authenticated as valid.

      For the intermediate layers 3, 5 and / or the cover layer 6, all materials commonly used in the art can be used. In this case, a transparent polymer material is typically used. The security feature layers 4 and 5 are normally transparent in areas other than the graphic structures 7, 8, 10 and 11, and in any case, in the area where the underlying security feature layer 4 or the base 2 graphic structure is located. Is transparent.

In FIG. 6, an apparatus for registering or incorporating graphic structures 7, 8, 10, 11 is shown. In the figure, the optical detection means 13 is shown. By this optical detection means, the substrate 2 is photographed together with the first and / or second confidential feature layers 4 and 5 applied thereon. Here, the first graphic structure 7 is incorporated in one of the confidential feature layers 4 and 5. However, the second confidential feature layer having the second graphic structure 8 has not yet been applied (for example by gluing) or the applied second confidential feature layer 5 has a second graphic structure ( Not yet incorporated (for example by laser engraving). The first graphic structure 7 is imaged by the optical detection means 13 and the generated electrical signal is used to position the second confidential feature layer 5 or the second graphic structure 8 to the second confidential feature layer. 5 is supplied to the control device 14 for incorporation into the system. Connected to the control device 14 is means 15 for applying the second security feature layer 5 or for incorporating the second graphic structure 8 into the second security feature layer 5 to the extent of an electrical signal. Therefore, it is controlled so that the first graphic structure 7 and the second graphic structure 8 are provided in register on the substrate.
