  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cross-sectional view illustrating an example of a layer configuration of an adhesive label including an anti-counterfeit medium according to an embodiment, and FIG. 2 is a schematic diagram illustrating an exemplary configuration of an anti-counterfeit medium according to the embodiment. FIG. 3 is a schematic diagram showing an example of a manufacturing process for manufacturing the forgery prevention medium according to the embodiment.

  As shown in FIG. 1, the adhesive label 1 </ b> A is laminated in the order of a label substrate 11, a diffraction structure forming layer 12, a reflective layer 13, a mask layer 14, a random pattern layer 15, a colored layer 16, and an adhesive layer 17. In addition, the diffraction structure formation layer 12-colored layer 16 part which comprises the adhesive label 1A is a forgery prevention medium. As shown in FIG. 1, the anti-counterfeit medium is provided with a window portion 18 for reading feature information indicating the feature of each article.

  Although the detailed formation method of the window part 18 is mentioned later, after the mask layer 14 is pattern-printed on the reflection layer 13, the window part 18 shape | molds the reflection layer 13 in a pattern shape by an etching, and matches this pattern. The random pattern layer 15 is formed by coating.

  Below, each layer 12-17 and the window part 18 are demonstrated.

  The diffractive structure forming layer 12 is a layer that is interposed between the label substrate 11 and the random pattern layer 15 and exhibits an optical effect due to diffraction. A relief-type diffraction grating or hologram is provided on the surface of the diffractive structure forming layer 12 facing the random pattern layer 15. The diffractive structure forming layer 12 has electromagnetic wave transmission (hereinafter referred to as light transmission) in optical observation, and is formed of a transparent or nearly transparent material (hereinafter “typically”). It is easy to make optical observations. In the present embodiment, when “optical” is described, the wavelength of the electromagnetic wave to be optically considered includes a visible light band, an infrared band including at least near infrared rays, and an ultraviolet band including at least near ultraviolet rays. Shall be included. The diffractive structure forming layer 12 may be omitted.

  As a method of forming the diffractive structure forming layer 12, first, a resin is applied onto the label substrate 11 using a bar coating method, and then the resin is dried to form a layer. Thereafter, there is a method of forming the diffraction structure forming layer 12 by forming, for example, a relief type diffraction grating on the surface facing the random pattern layer 15. The relief type diffraction grating, for example, generates interference fringes by irradiating the surface of the photosensitive resin with two coherent rays using the two-beam interference method, and the interference fringes are formed in the form of irregularities. It is formed by recording on a photosensitive resin. It is possible to record an arbitrary three-dimensional image as a diffraction grating pattern by selecting two light beams, and it is also possible to record a different image (that is, a changing image) according to an observation angle. The method for recording the image pattern on the diffractive structure forming layer 12 is not limited to the two-beam interference method. For example, a well-known hologram manufacturing method such as an image hologram, a Lippmann hologram, a rainbow hologram, or an integral hologram may be used. Good.

  Further, as another method for forming the diffractive structure forming layer 12, after forming a layer by applying a resin on the label substrate 11, the press plate for forming the diffractive structure is heated using a roll embossing method, There is a method of forming the diffractive structure forming layer 12 by forming an embossed shape on the layer surface.

  The method for forming the diffractive structure forming layer 12 is not limited to the above method, and any method that can form a layer having a diffractive structure is applicable.

  Moreover, as resin used in order to form the diffraction structure formation layer 12, a thermoplastic resin, a thermosetting resin, an ultraviolet-ray, an electron beam curable resin, etc. are applicable, for example. As the thermoplastic resin, for example, an acrylic resin, an epoxy resin, a cellulose resin, a vinyl resin, and the like are applicable. In addition, as the thermosetting resin, urethane resin, melamine resin, phenol resin, and the like obtained by adding polyisocyanate as a crosslinking agent to an acrylic polyol or polyester polyol having a reactive hydroxyl group can be applied. . Furthermore, as the ultraviolet or electron beam curable resin, epoxy (meth) acryl, urethane (meth) acrylate, and the like are applicable. In addition, even if it is resin other than the above, if it is resin which can form a diffraction structure, it is applicable suitably.

  The reflective layer 13 partially covers the surface of the diffraction structure forming layer 12 on which the diffraction grating or hologram is provided, and is a layer that improves the diffraction efficiency of the diffraction structure formation layer 12. The reflective layer 13 need not be formed so as to be in direct contact with the diffractive structure forming layer 12, but when the diffractive structure forming layer 12 is a relief type diffraction grating, the reflective layer 13 is in direct contact with the concavo-convex pattern. Need to be formed. Note that the reflective layer 13 may be omitted.

  As a method for forming the reflective layer 13 into a pattern, there is a method in which a mask layer 14 using an acid resistant or alkaline resistant resin is positively printed on the reflective layer 13 and then the reflective layer 13 is etched with acid or alkali. In addition, the said pattern shaping | molding method is an example, and the technique which forms the reflection layer 13 partially well-known can be applied suitably.

  Moreover, as a material used for forming the reflective layer 13, a metal thin film with high reflected luminance is preferable, and for example, Al, Sn, Cr, Ni, Cu, Au, brass, and the like are applicable.

As described above, the mask layer 14 is a layer used when the reflective layer 13 is formed into a pattern. The mask layer 14 is light transmissive and typically transparent. If the patterning is not necessary, the mask layer 14 may be omitted. In this case, both the laminated structure and the manufacturing process can be simplified. In this case, R unit shown in FIGS. 2 and 3 (i.e., the region where the reflective layer 13 does not exist) can not be formed, and there is a possibility that by performing the optical observation of the random pattern image I _R is difficult to be described later.

Random pattern layer 15 is a layer in which the irregularly shaped, when optically observed, as shown in FIG. 2 is a layer for displaying a random pattern image I _R. The random pattern image I image _R is with a continuous tone (hereinafter, the grayscale image hereinafter) A, has a distribution of brightness corresponding to the shape of the random pattern layer 15. Note that the irregular shape of the random pattern layer 15 is not artificially generated, but is a naturally occurring property. Therefore, the random pattern layer 15 can be used like a fingerprint or a retina for personal identification. The random pattern layer 15 may be omitted.

  As a method of forming the random pattern layer 15, gravure coating printing can be applied. For example, a gravure in which a groove for providing a non-image portion is formed so as to coincide with the P portion shown in FIGS. The random pattern layer 15 is formed by pattern printing using a plate.

  The random pattern layer 15 is formed of a pigment and / or dye and a material having a low affinity with the pigment / dye, and is formed of, for example, a mixture of a white pigment and a cured resin such as silicone. Further, the random pattern layer 15 may be formed of a functional material other than the pigment or dye instead of the pigment or dye. Furthermore, the random pattern layer 15 may be formed of at least one of a pigment and a dye and a functional material other than the pigment and the dye.

  The functional material used for forming the random pattern layer 15 includes, for example, an infrared absorbing material, a fluorescent material, an ultraviolet absorbing material, liquid crystal particles, a material imparting optical characteristics such as silica, an antistatic agent, and the like. Materials that impart electrical properties such as conductive materials; materials that impart magnetic properties such as magnetic powder; materials that impart design properties such as aluminum powder and glass particles; or combinations of two or more thereof Is possible.

  The colored layer 16 is a layer formed on the random pattern layer 15 and is typically a dark layer such as black. Further, as a method of forming the colored layer 16, gravure coating printing or the like can be applied as in the case of the random pattern layer 15. The colored layer 16 may be omitted.

  The adhesive layer 17 is a layer formed on the colored layer 16 and is formed using a thermoplastic resin or the like.

  The window portion 18 enables the feature information to be read, and is formed by forming the diffraction structure forming layer 12 to the colored layer 16 using the pattern printing method.

  Here, a method for forming the anti-counterfeit medium and a method for forming the window 18 will be described.

  First, the diffractive structure forming layer 12 and the reflective layer 13 are formed on the label base material 11 using the above-described method.

  Subsequently, the mask layer 14 is formed on the layer surface of the reflective layer 13 excluding the region where the P portion and the R portion shown in FIG.

  Next, the reflective layer 13 laminated in the region where the P portion and the R portion are located is removed by etching.

  Subsequently, the random pattern layer 15 is formed on the mask layer 14 using gravure coating printing. More specifically, as shown in FIG. 3B, the random pattern layer 15 is formed on the mask layer 14 by pattern printing using a gravure plate in which grooves are dug in accordance with the P portion.

  Thereafter, the colored layer 16 is formed on the random pattern layer 15 in the same manner as the random pattern layer 15.

  When the anti-counterfeit medium is formed as described above, the window portion 18 is formed in the region where the P portion is located. Thus, when the window part 18 is formed using the printing method, the window part 18 with a sharp edge can be produced. Therefore, it becomes easy to align the characteristic information observed from the window 18 (in other words, focusing or focusing), so that improvement in reading accuracy can be expected. When this anti-counterfeit medium is applied to an adhesive label, the label base material 11 is located on the outermost surface of the adhesive label, so that an area where feature information observed from the window 18 is located (hereinafter referred to as a feature information reading area). Deterioration).

  For example, when the article is paper, the characteristic information is a random pattern (hereinafter referred to as a paper pattern) indicated by complexly intertwined plant fibers.

  Feature extraction is performed by an optical method, for example, optical continuous spectrum light, light with multiple single spectrum lights superimposed, single spectrum light, light with spatially and spatially coherence, or these The superimposed light is irradiated onto a region including the feature information, and an image of the region is photographed or photographed, or a diffused light pattern (including a laser speckle pattern) from the region is photographed. The feature information is discriminated from other feature information using the captured image itself or a value obtained by extracting and indexing (quantifying) the feature from the image.

  In the present embodiment, the shape of the window 18 is circular. However, when the shape of the window 18 is circular, as shown in FIG. It is necessary to provide a feature point for specifying The feature points in this case are, for example, a small circular window provided in the vicinity of the outer periphery of the window 18, an opaque point located within the circle of the window 18, and the like.

  Moreover, in this embodiment, although the shape of the window part 18 was circular, it is not limited to this. As the shape of the window 18, for example, a polygon as shown in FIG. 4B, a shape in which a part of a circle or a polygon is missing, a non-polygon shape having a vertex, or the like can be applied as appropriate. When the shape of the window portion 18 is a polygon or a non-polygon having a vertex, the acute angle that forms the polygon functions as a feature point, so that it is not necessary to newly provide a feature point.

[First Modification]
FIG. 5 is a cross-sectional view showing a modification of the layer configuration of the pressure-sensitive adhesive label including the forgery prevention medium according to the embodiment.

  In this case, in the forgery prevention medium, as shown in FIG. 5, a through-hole 18 ′ that penetrates from the diffraction structure forming layer 12 to the colored layer 16 is provided instead of the window portion 18. Note that the through hole 18 ′ needs to penetrate at least the reflective layer 13 to the colored layer 16.

  As a method of forming the through hole 18 ′, there is a method of making a hole mechanically. At this time, the through hole 18 ′ may be formed by penetrating to the label base material 11, or the through hole 18 ′ may be formed without penetrating the label base material 11 by half cutting or the like. If the through hole 18 'is formed without penetrating the label base material 11 by half-cutting or the like, the label base material 11 remains on the outermost surface of the adhesive label 1A' containing the forgery prevention medium. Can be prevented.

  When the through hole 18 ′ is formed instead of the window portion 18 in this way, the reflective layer 13, the random pattern layer 15, and the colored layer 16 constituting the forgery prevention medium are aligned so that the feature information can be read. Therefore, the forgery prevention medium can be generated more easily than the above pattern printing method.

[Second Modification]
FIG. 6 is a cross-sectional view illustrating an example of a layer configuration of a transfer foil including a forgery prevention medium according to the embodiment.

  In this case, a peelable protective layer 19 is formed on the support 11 ′, and the laminated structure below the peelable protective layer 19 is formed in the same manner as the pressure-sensitive adhesive label shown in FIG.

  The transfer foil 1B is heated and pressed on a base material (article) such as coated paper, and then transferred to the article by peeling off the surface support 11 ′ (that is, integrated). . Moreover, since the peeling protection layer 19 is formed on the support 11 ′, the peeling protection layer 19 is located on the outermost surface even after the support 11 ′ is peeled off from the article, and serves as a protection layer. Therefore, it is possible to prevent deterioration of the feature information reading area.

[Description of an example of authenticity determination processing]
The anti-counterfeit medium according to this embodiment is used for authenticity determination of an article by the following method, for example.

  Here, the case where the adhesive label or transfer foil containing a forgery prevention medium is applied to a banknote is demonstrated.

In addition, when the manager who issues / manages the banknote issues the banknote, the adhesive label or the transfer foil including the forgery prevention medium is attached to the banknote, and the identification number information indicating the banknote identification number printed on each banknote; an image information representing a random pattern image I _R to be displayed by the random pattern layer 15 constituting the medium for preventing forgery, a paper fingerprint information indicating a paper fingerprint observed through the window portion 18 or the through-hole 18 'of the medium for preventing forgery Are registered in a database (not shown).

  First, a case where a general user performs authenticity determination will be described.

  The banknote owner who owns the banknote captures an image using, for example, a camera of a mobile phone, for example, in order to determine whether the banknote is authentic, and image information indicating the captured image Is sent to a database (not shown).

  When the database receives image information transmitted from the banknote owner, it determines whether image information that matches the received image information is registered, and indicates that the determination result is registered. Reads out the identification number information associated with the image information. Thereafter, the database transmits the read identification number information to the banknote owner's mobile phone.

  When the banknote owner receives the identification number information transmitted from the database using the mobile phone, does the identification number indicated by the received identification number information match the identification number printed on the banknotes owned by the banknote owner? It is possible to check whether or not to make a true / false decision.

  Next, a case where the bank performs a true / false determination more strictly using a dedicated machine will be described.

  A verifier (e.g., a bank clerk) who executes the authenticity determination process executes the authenticity determination process using a dedicated machine. The dedicated machine reads the paper pattern information indicating the paper pattern observed from the window 18 or the through hole 18 ', and then transmits the paper pattern information to the database.

  When the database receives the paper pattern information transmitted from the dedicated machine, the database determines whether paper pattern information matching the received paper pattern information is registered, and indicates that the result of the determination is registered. In this case, identification number information associated with the paper pattern information is read out. Thereafter, the database transmits the read identification number information to the dedicated machine.

  When the dedicated machine receives the identification number information transmitted from the database, the verifier determines that the identification number indicated by the identification number information received by the dedicated machine is the identification number printed on the banknote on which the authenticity determination process is performed. It can be checked whether or not they match, and authenticity determination can be performed.

  In addition, although this embodiment demonstrated the case where the adhesive label or transfer foil containing a forgery prevention medium was applied to the banknote, it is not limited to this, For example, you may apply to glass, cloth, etc.

  According to the embodiment described above, the feature information reading area can be visually recognized by the configuration including the window 18 inside the medium body, and the authenticity can be obtained without taking time for focusing when executing the authenticity determination process. Judgment processing can be executed.

  In addition, even if the section is divided between the P section and the R section, the feature point is located in the vicinity of the window section 18, so that the feature information reading area is accurately specified when executing the authenticity determination process. be able to.

  Furthermore, when the anti-counterfeit medium attached to the article is peeled off from the article, the outermost surface shape of the article (for example, the state of the paper fibers) changes, so that the authentication pattern in the feature information reading area is not reproduced. For this reason, when a forged medium is pasted on the same place, the action can be detected.

[Description of Modified Example of Authenticity Determination Processing]
Here, another example of the authenticity determination process will be described with reference to the schematic diagrams of FIGS.

7, the anti-counterfeit medium 100 exists R unit, random pattern image I _R is present in some or all of the R portion. Further, the anti-counterfeit medium 100 has a P portion (hereinafter, in the description, it can be appropriately read as the window portion 18 or the through hole 18 ′ provided in the P portion).

  As shown in FIG. 7, the forgery prevention medium 100 is fixed by being adhered or adhered to the article 101.

  A code A may be printed or formed on a portion corresponding to the window 18 or the through hole 18 ′ of the article 101. The contents of the code A and the printing or forming procedure will be described later with reference to FIG.

  The anti-counterfeit medium 100 may be provided with another P ′ portion having the same function as the P portion (that is, the window portion 18 or the through hole 18 ′) described with reference to FIGS. In the description, it is assumed that the P ′ portion is provided with another window portion 18 ″ having the same function as the window portion 18 or the through hole 18 ′). A code B may be printed or formed on a portion corresponding to the window portion 18 ″ of the article 101. The contents of the code B and the printing or forming procedure will be described later together with the description of FIG.

  The code C may be printed or formed on the forgery prevention medium 100. The contents of the code C and the printing or forming procedure will be described later together with the description of FIG.

  A code D may be printed or formed on the article 101. The contents of the code D and the printing or forming procedure will be described later together with the description of FIG.

Code A, code B, at least some of the code C, the code D information, there is correspondence between the random pattern image I _R.

  A code E different from the code D may be printed or formed on the article 101. The contents of the code E and the printing or forming procedure will be described later together with the description of FIG.

  By providing the code A in the window 18 or the through hole 18 ′, when the feature quantity of the article 101 is optically extracted through the window section 18 or the through hole 18 ′, the code A and the feature quantity of the article are simultaneously obtained. There is an effect that can be easily obtained. Typically, it is not necessary or easy to adjust the positioning and focusing of the optical measurement position for each of the code A and the feature amount of the article.

  By providing the code A in the window 18 or the through-hole 18 ', when the feature amount of the article 101 is optically extracted through the window 18 or the through-hole 18', the outline of the window 18 or the through-hole 18 'is obtained. There is an effect that the feature amount of the article can be aligned using not only the shape but also the shape such as the outline of the code A. Typically, the marker pattern considering the positioning of the optical measurement position and the convenience of focusing is formed so as to be included in the outline of the window portion 18 or the through-hole 18 ′ or the outline shape of the code A. This effect is achieved by setting

  If the window 18 has a protective layer in the window 18 or the through hole 18 ′ or the window 18 ″ by providing the code A or the code B, respectively, the code A or the code B is the lower part of the protective layer. Therefore, there is an effect of strengthening against external damage including fouling and abrasion.

By providing the code C on the medium for preventing forgery 100, and a random pattern images I _R and the code C is present on the same medium for preventing forgery 100. Thus, when taking or imaging a random pattern image I _R, at the same time in the case of imaging or imaging the code C, such as analyzing by an image analyzer which is not visible or shown on each shot or captured images means makes it possible to the random pattern image I _R and the code C is to clarify that the cut or damage is not between the predetermined there on the positional relationship, and a random pattern images I _R and the code C. In order to clarify the positional relationship between the random pattern image I _R and the code C, or to form a marker indicating at least a portion the position of the code C of the contour of the R unit, a random part of the contour of the code C or forming a marker indicating the position of the pattern image I _R. These things, it is possible to clarify the positional relationship between the random pattern image I _R and the code C, it is possible to further improve the effect described above.

Since the code C is on the anti-counterfeit medium 100, the manufacturer of the anti-counterfeit medium 100 (or the anti-counterfeit medium manufacturing apparatus possessed by the manufacturer of the anti-counterfeit medium 100) or the person who received the instruction (or received the instruction) The forgery prevention medium manufacturing apparatus possessed by a person has an effect that can be printed or formed. That is, in the case of the code A, the code B, and the code D, since these codes exist on the article 101, the code is printed or formed by the manufacturer of the article 101 (or the article manufacturing apparatus possessed by the manufacturer of the article 101). Alternatively, it may be basically performed by a person who has received the instruction (or an article manufacturing apparatus possessed by the person who has received the instruction). When anti-counterfeit medium 100 and the required product liability decomposition of an article 101 (e.g., if each manufacturer is different, etc.), code having information related to a random pattern image I _R is as code C, the medium for preventing forgery It may be preferable to mount on 100. The random pattern image I _R , the process of creating the contents of the code C so as to at least partially have the encoded information of the image information, and the process of printing or forming the code C are designated as the manufacturer of the anti-counterfeit medium 100. (Or an anti-counterfeit medium manufacturing apparatus possessed by the manufacturer of the anti-counterfeit medium 100) has an effect of facilitating separation of the responsibility for manufacturing the anti-counterfeit medium 100 from the responsibility for manufacturing the article 101.

It shall be.

Information of the random pattern image I _R obtained by the receiver 134 are digitized by the processing unit 131, granted another part of the digital information from the digital information and a memory 137 from optionally auxiliary information generator 136 Information conversion A is performed as necessary, and another part of the digital information from the memory 137 is added to become the contents of the code X.

An example of the processing of the digitized information of the random pattern image I _R, the whole or a part of the image or be one which digital data, encryption processes the digital data, compression processing, hashing, CRC calculation or be those treated, or random pattern image I all or extracts a portion of the feature point digitization of _R (further, the encryption processing, compression processing, hash processing, including those CRC value calculation process) was There are cases, and there are cases where they are combined. As other examples of converting random patterns into digital data, there are some known techniques such as face image authentication, iris pattern authentication, fingerprint authentication, vein pattern authentication, and the like.

The content of the auxiliary information generator 136 is random data of a fixed length or indefinite length, or an ID number such as a serial number that increases (or decreases) by a fixed amount every time shooting or imaging, or a random pattern image or a procedure or information required to digitize the I _R (including information providing slice level or gray level for digital data), authentication information of the digitized information of the random pattern image I _R (e.g., random pattern image I _R digitized information may be hashed or encrypted, or a combination thereof. Using such auxiliary information generator 136, and if the contents of the auxiliary information generator 136 is not the random data, ancillary when analyzing the code X with respect to the digital data obtained from the random pattern image I _R such information is available, further information about the random pattern image I _R is obtained, made to digital data and analysis of the random pattern image I _R is quick and fast, and effective there to improve the reliability of the code. Also, if the content of the auxiliary information generator 136 comprises a random data is not obtained auxiliary information to digital data obtained from the random pattern image I _R from the random data, the information conversion A code X after performing to be able to give randomness, making it difficult to find regularity between the random pattern image I _R and code X, advantageous effect is attained which can be improved the security of the system . By setting the data length of the random data to a fixed length, or by performing specific data marking at the start and end points of the random data, only the random data is extracted and deleted when the code X is decoded. I can do it.

The contents of the memory 137 may be an ID number of the registration device 130, a digital signature that proves the authenticity of the registration device 130, a key necessary for encryption processing, or the like. By using such a memory 137, when analyzing the code X, reliability information relating to the random pattern image I _R is obtained. Thereby, there is an effect that the reliability of the code X and the whole system can be improved.

  Information about the information conversion A and information about the service type can be added to the contents of the memory 137. As an example, information about the information conversion A and a service type are registered in a portion of the code X that is not information that has undergone the information conversion A. In this case, since the information is a part that has not been converted by the information conversion A, even if there is no knowledge about the information conversion A, the information can be recognized only by reading the code X.

  Information conversion A includes cryptographic processing (including public key cryptography and common key cryptography), reversible transformation (including data compression processing and keyed data compression processing), and irreversible transformation (including hash processing and CRC value calculation processing). ), And there is a case where no conversion is performed (the same value as the original value even if the information conversion A is performed, that is, equivalent conversion).

  Here, typically, an encryption method is considered. In the case of the public key method, typically, the secret key is in a secret state that only the producer of the code X can know, and the public key is generally disclosed by the generator of the code X. In the case of the common key method (including keyed data compression), the common key is typically not disclosed.

  The processing unit 131 determines the content of the code X by the above processing. The actual code X representing this content may be a sequence of numerical values or characters, a one-dimensional barcode, or a two-dimensional barcode. Or any other optically recognizable code. In addition, although the description has been made mainly on the optical code with respect to the code X, the code may be magnetically recorded.

  After the content of the code X is determined, the processing unit 131 sends an instruction to the printing machine 139 to print the code X on a predetermined portion of the anti-counterfeit medium 100 or the article 101. In addition to printing, it includes the formation of the code X by the electromagnetic action of a light source (including a laser) and the alteration, deformation, discoloration, evaporation and vapor deposition due to the thermal action of the heat source, and other actions. Further, a code printed or formed on a separate material or sheet is used as a code X, and the code X is formed by attaching to a predetermined portion of the anti-counterfeit medium 100 or the article 101 (including pasting, adhesion, adhesion, etc.) Including.

  A specific example of printing by the above-described printing machine 139 will be described below. That is, when the anti-counterfeit medium 100 is a seal, the printing surface (uppermost surface) of the anti-counterfeit medium 100 is a base material for the seal, and typically PET or the like is used. In order to place printing on the PET surface, generally, the surface of PET is subjected to easy adhesion processing, and thermal transfer printing is performed on the surface by inkjet printing or a thermal printer. The portion of the code X having a fixed value may be subjected to screen printing or the like to reduce the trouble of ink jet printing or thermal transfer printing. Next, in the case where the anti-counterfeit medium 100 is a foil, and after being attached to the article 101, the printed surface (uppermost surface) becomes a protective layer / release layer of the foil. As in the case of the seal, ink jet printing or thermal transfer printing is used, and screen printing is used in some cases. Next, when the anti-counterfeit medium 100 is a foil and before being attached to the article 101, the surface to be printed (the protective layer of the foil / the surface of the release layer) is not exposed at the time of printing, so inkjet printing or thermal transfer It is difficult to use printing. In this case, laser engraving (laser printing) is performed on the reflection layer of the hologram. In this case, if the laser irradiation is performed from the opposite side of the random pattern layer with respect to the reflective layer, the processing (printing) can be performed efficiently. This laser engraving (laser printing) can be performed before or after the foil is attached to the article 101, and can be performed even when the anti-counterfeit medium 100 is a seal.

  In printing or forming the code X, a conveyance machine or a positioning device (not shown) may be used according to an instruction from the processing unit 131.

  The code X is illuminated by the light source 138 according to an instruction from the processing unit 131 and is photographed or captured through the optical system 135 and the receiver 134.

The obtained video is restored as digital information indicating the contents of the code X by the processing unit 131. This digital information, the information digital data by using a random pattern image I _R above, the auxiliary information the information generator 136, and the contents of the code X created through the information conversion A from the information in the memory 137 information and If the information matches, the printing (or formation) of the printing machine 139 is regarded as successful. By performing such confirmation, there is an effect that the code X can be printed or formed reliably.

Processing unit 131, random digital information pattern image I _R, the digital information from the auxiliary information generator 136, the digital information from the memory 137, the digital information through the information converting A, key information related to information conversion A, code In addition to digital information and decoded information of the captured image of X, various information related to manufacture of the forgery prevention medium 100 is collected as necessary, such as a manufacturing number, a manufacturing lot number, a manufacturer, a manufacturing apparatus, a date and time. And sequentially register in a database M (not shown) connected to the processing unit 131.

Random pattern image I _R for photographing or generation of code X containing imaging and the printing or formation of the anti-counterfeit medium 100, carried out by the manufacturer of the medium for preventing forgery 100 (or, registration device 130 by the manufacturer have) This can be done independently of the manufacturer of the article 101 (or the manufacturing apparatus owned by the manufacturer). Therefore, the manufacturer of the article 101 can manage the manufacturing responsibility of the article 101 while making a relatively good separation from the manufacturer's responsibility of the anti-counterfeit medium 100, thereby facilitating industrial transaction rules. There is an effect that can be clarified. Hereinafter, regarding the case where the code X is the code C, the manufacturer of the forgery prevention medium 100 and the manufacturer of the article 101 will be described separately.

  The manufacturer of the article 101 receives the forgery prevention medium 100 from the manufacturer of the forgery prevention medium 100. At this time, the information stored in the database M related to the received one or more anti-counterfeit media 100 is stored in an off-line medium such as a print medium, an optical disc or a magnetic tape, or through online communication such as a network. Another manufacturer operated by the manufacturer of the article 101 (or another manufacturer operated by the manufacturer of the article 101) from the manufacturer (or the processing unit 131 of the registration device 130 operated by the manufacturer of the anti-counterfeit medium 100 or the database M connected thereto). The data is transferred (or transferred) to the processing unit of the registration machine 130 or the database M connected thereto. If the registration machine 130 operated by the manufacturer of the anti-counterfeit medium 100 and the registration machine 130 operated by the manufacturer of the article 101 are the same (including the case where they are shared), nothing is done or the reading authority is changed. As a result, the manufacturer of the article 101 (or the processing process in the processing unit 131 of the registration device 130 registered by the manufacturer of the article 101) can refer to information and write necessary information.

  Next, the anti-counterfeit medium 100 is fixed to the article 101 by adhesion or adhesion, and a code E is printed or formed on the article 101 by the printer 139 in accordance with an instruction from the processing unit 131 in the registration machine. The code E is information that the manufacturer of the article 101 has information related to the article 101, and is a code for each product type as seen in a bar code or the like, and a different ID number (including a serial number). In some cases, the unique number of the article 101 is included. The unique number here is, for example, a numerical value of a certain rule (for example, one of prime numbers greater than 10000 or 16 greater than 1000 when combined with an encryption key that is known to the manufacturer of the article 101 and is not disclosed to the public). Any number of multiples, etc., including a numerical value generated by the processing unit 131 or the like according to the certain rule and encrypted with a secret key. Alternatively, a number is randomly selected from the range (or number space) that the unique number can take, and the selected number is registered as an issued unique number in the database. Including those that determine whether Alternatively, a unique number is appropriately selected, and the unique number is assigned with a hash value of the unique number encrypted by a secret key that is known to the manufacturer of the article 101 and is not disclosed to the public. The printed code E is photographed or captured by the optical system 135 and the image receiver 134 under the illumination of the light source 138 and coded by the processing unit 131. This result is compared with the content of the code that the processing unit 131 instructs the printing machine 139 to print, and if it matches, the code E is regarded as being printed (or formed) correctly, and quality control is possible. Yes.

Manufacturer of the article 101 (or, registration device 130 with the manufacturer of the article 101) is photographed or imaged random pattern images I _R and code X illuminated to the light source 138, the digital data obtained from them, counterfeit It is compared with the data received from the manufacturer of the prevention medium 100 and its correctness is confirmed.

Further, the feature quantity of the article 101 corresponding to the window part 18 or the through hole 18 ′ illuminated by the light source 138 through the window 18 or the through hole 18 ′ is photographed by the receiver 132 through the optical system 133. Or it is imaged. This information is processed by the processing unit 131 and converted into digital information. This conversion is the same as contemplated for conversion into digital information of the random pattern image I _R, not necessarily using the same algorithm.

There may be one light source 138 or a plurality of light sources. The light source 138 appropriately has a wavelength, wavelength band, and spatiotemporal coherency suitable for optical observation. For example, when a speckle pattern or an interference pattern is imaged through the window 18 or the through hole 18 ′, a light source such as a laser having sufficient spatiotemporal coherency may be used. At the time of imaging of the random pattern image I _R, coherency if such unstable interference pattern too high prevents imaging of high-precision, low LED light source or a mercury lamp or the like coherency, using a general light source. Even if a separate optimum light source is prepared for each region, the light source may be shared.

In this way, the manufacturer of the article 101 (or the registration machine 130 owned by the manufacturer of the article 101) stores the random pattern I _R , code X, code E, window portion in the database M connected to the processing unit 131. 18 or the through-hole 18 ′, the feature quantity of the article 101 (corresponding to the feature A and the feature B shown in FIG. 8) is stored, and the production number, production lot number, manufacturer Various information related to the manufacturing of the article 101 is stored.

  Next, the case where the code X is any one of the code A, the code B, and the code D will be described.

The anti-counterfeit medium 100 is a random pattern image I _R is printed or formed.

Similar to the case of the code C (indicating that the code X is the case for code C), the contents of the code X from the random pattern image I _R is produced.

  A code X is printed or formed on a predetermined portion of the article 101 by the printing machine 139.

  Next, the anti-counterfeit medium 100 is fixed to the article 101. At this time, in the case of the code A or the code B, these codes are observed from the corresponding window portion 18 or the through hole 18 ′ and the window portion 18 ″ (the protective layer may or may not be present). Adjust the fixed position as possible. In addition, when there exists a protective layer in the window part 18 or through-hole 18 ', and window part 18' ', the code | cord | chord X will be printed or formed on those protective layers. The code X is photographed or imaged, restored as digital information, compared with the information of the contents of the original code X, and the validity of printing or forming is verified.

  As in the case of the code C, the code E is printed or formed on the article 101 by the printing machine 139 and photographed or imaged by the receiver 134 to verify the contents.

  As in the case of the code C, the feature amount of the article 101 through the window 18 or the through hole 18 ′ is converted into digital information.

In this way, the manufacturer of the article 101 (or the registration machine 130 owned by the manufacturer of the article 101) stores the random pattern image I _R , code X, code E, window in the database M connected to the processing unit 131. The feature quantity of the article 101 through the section 18 or the through-hole 18 'is stored, and further, the manufacture number, the production lot number, the manufacturer, the manufacturing apparatus, the date and time, and the manufacture of other articles 101 according to the needs of the manufacturer of the article 101 Stores various information related to

  The processing unit 131 includes a CPU, a memory, a program on the memory, information on the memory necessary for executing the program, an input / output device, a power source, and the like. Information and programs necessary for the operation and processing are provided. Information necessary for processing of the auxiliary information generator 136, information, and information in the memory 137 are connected to the processing unit 131, and are appropriately registered, corrected, and updated by an operation device, a display device, and an input / output device (not shown). Alternatively, registration, correction, and update are appropriately performed by the control terminal 123 connected to the registration device 130 through the network.

The processing device 120 includes a CPU, a memory, a program on the memory, information on the memory necessary for executing the program, an input / output device, a power supply, and the like. The processing device 120 creates information and a program necessary for processing of the processing unit 131, information and a program necessary for processing of the auxiliary information generator 136, and information of the memory 137 according to the instruction input from the input device 121, The information is sent to the processing unit 131, or information or a program necessary for processing of the processing device 180 is created and sent to the processing device 180. In these cases, the display device 122 is used as appropriate to notify the operator of the control terminal 123 of the processing contents and the like.

  The connection between the registration machine 130 and the control terminal 123, the connection between the authentication system 189 and the control terminal 123, and the connection between the registration machine 130 and the authentication system 189 may be via a network, IC card, USB memory, optical disk, An off-line method such as a magnetic disk or a magnetic tape may be used, and it is not necessary to limit to any method.

  Information related to the anti-counterfeit medium 100 and the article 101 stored in the database M connected to the processing unit 131 of the registration machine 130 is a database connected to the processing device 180 via the connection between the processing portion 131 and the processing device 180. 182 is accumulated. Information stored in the database 182 is an encryption key 183, a service identifier 185, a service authorization condition 186, and a table 184 based on data obtained from the database M through the processing unit 131.

  The service identifier 185 is information that defines a service that can be executed by the authentication system 189.

  The encryption key 183 may be an encryption key used when creating the code X. A plurality of encryption keys 183 may be provided, and an encryption key for authenticating a request to the authentication system 189 may be selected as one of them.

  The service authorization condition 186 defines permission conditions for the authentication system 189 to provide a service in response to an external service request. When there are a plurality of service request sources, the service request source, the authorization conditions, and the permission There is a case where it is formed as a list indicating a time limit or the like. For example, the service authorization condition indicates a condition that the service requester has an encryption key provided to the service requester (that is, issued by the processing device 180) or that the license is within the expiration date. In this case, the service requester encrypts the encryption key with the encryption key of the authentication system 189 and then sends it to the processing device 180. The processing device 180 decrypts the obtained message with the private key corresponding to the encryption key, confirms whether the encryption key matches the one provided to the service requester, and confirms from the list whether it is within the expiration date To do. This determines whether to authenticate the service requester. These authentication processes may be performed by a widely used one.

  In addition to the information of the database M, the table 184 includes a registration date, a registrant, a status, and the like when the table 184 is registered in the database. The status indicates the state of the article 101, and the state of the article 101 is recorded when the authentication system 189 receives notification of information about the article 101. Further, it may include the time when the notification is received, the information of the notification source, or the history and answer status when the information inquiry is received.

By constructing the configuration of the registration device 130 as described above and adopting the operation procedure described above as the operation procedure of the registration device 130, the combination of the forgery prevention medium 100 and the forgery prevention medium 100 and the article 101 is always accurate.

  In FIG. 9, a terminal 140 includes an image receiver 147 combined with an optical system 146, a battery 141, an audio generator 142, a communication device (including a communication device and a communication unit) 143, an operation device 144, a display device 145, and a memory 148. And a processor 149 connected thereto.

  As shown in FIG. 9, the communication system 179 includes a processing device 170, a database 173 connected to the processing device 170, a communication device 171 connected to the processing device 170, and a communication unit 172 connected thereto (typically wireless). Antenna and connection port for wired connection).

  The processing device 170 includes a CPU, a memory, a program on the memory, information on the memory necessary for executing the program, an input / output device, a display device, a power supply, and the like.

  The communication device 143 communicates with the communication device 171 through the communication unit 172. This communication may be wireless or wired. Through communication, the terminal 140 transmits terminal information recorded in the memory 148 in the terminal 140 to the processing device 170. The processing device 170 determines whether or not a communication service can be provided to the terminal with reference to the table 174 on the database. The table 174 stores terminal IDs, authentication information, service contract types, billing information, and other information. The service contract type indicates the type of service that can be provided to the terminal. When the service contract type indicates that the service contract type can be provided, the communication system 179 processes the service stored in the processing device 170. Service processing is performed according to the method, and billing information is updated. Note that it is assumed that the communication system 179 and the terminal 140 are in a state of authenticating each other by a known authentication method. For security purposes, communication may be concealed by encryption or the like.

  The authenticated content distribution system 159 includes a processing device 150 and a database 152. The processing device 150 includes a CPU, a memory, a program on the memory, information on the memory necessary for executing the program, an input / output device, a display device, a power supply, and the like. The database 152 stores an encryption key 153, a service type 156, a table 154, and a content body used in the information conversion A.

  The authentication content distribution system 159 is a system for distributing purposeful binary data, scripts, XML data, objects, parameter data, and other programs that can be executed in various terminals and execution environments. Information to be prepared differs depending on the type of system (OS, execution environment, version thereof, etc.) used in the terminal. The table 154 lists which programs and data are required according to combinations of terminal types and system types. If these lists are different for each service type, such a list is constructed for each service type, or a table is constructed as a list including the service type.

  The content main body 155 stores the substance of programs and data to be provided corresponding to the search results of the table 154.

  The service identifier 156 provides information for identifying a service performed by the authentication content distribution system 159.

  When the operator of the terminal 140 wishes to confirm the legitimacy of the forgery prevention medium 100 and the article 101 to which the anti-counterfeit medium 100 is fixed, the operator of the terminal 140 operates the operating device 144 or the terminal 140 The processor 149 establishes communication with the communication system 179 by sending an instruction to the processor 149 to confirm the validity via an input / output device (not shown). If the terminal 140 has not yet obtained the necessary authentication content from the authentication content distribution system 159, it communicates information requesting to download the authentication content. For these communications, authentication information in the database 173 is used.

  The communication system 179 receives a download request from the terminal 140 and refers to the service type registered in the service contract type in the table 174 to confirm whether the terminal is in a contract for providing a download service. If a contract is made, the communication system 179 establishes a connection between the terminal 140 and the authentication content distribution system 159. When there are a plurality of authentication content distribution systems 159, the communication system 179 selects an authentication content distribution system 159 to be connected according to the contents of the service contract, and then establishes a connection therewith.

  The terminal 140 communicates the requested service type and terminal type to the authentication content distribution system 159. The authentication content distribution system 159 checks whether or not the requested service type is correct, and if it is correct, the authentication key 153 corresponding to the service type and the program number in the table 154 corresponding to the service type and terminal type are obtained. The content including the program body corresponding to the program number is returned to the terminal 140.

  During or at the end of communication, the communication system 179 calculates a charge value for this service, and updates the charge information in the list of terminal IDs in the table 174 (or adds the calculated value to the charge information). . In response to the billing information stored in the communication system 179, the operator of the communication system 179 collects a fee from the charge payer of the terminal 140, and provides a predetermined fee to the operator of the content distribution system for authentication from there. .

  When the user of the terminal 140 starts, ends, or continues the use service of the authentication content distribution system 159, the operator of the communication system 179 is notified to that effect, and the operator of the communication system 179 displays the table 174. The service contract type corresponding to the ID of the terminal 140 is updated.

  It should be noted that there is a case where it is difficult for the user of the terminal 140 to know information on the service type to be requested to the authenticated content distribution system 159. As an example of the correspondence in this case, a service identifier may be placed in a portion other than the portion subjected to the information conversion A processing of the code X. As a result, the service identifier can be obtained without knowledge about the information conversion A, and the operator of the terminal 140 sends it to the communication system 179. If a new contract is required, the contract management of the communication system 179 and the terminal 140 is performed. A service usage contract is signed with the subscriber. After the contract is concluded, the communication system 179 registers the new service type as available in the service contract type in the table 174, and the communication system 179 sends the service use request from the terminal 140 to the authentication content distribution system 159. To perform the communication described above.

  Also, the terminal 140 transmits the version and date of the authentication content acquired by the terminal 140 to the authentication content distribution system 159 through the communication system 179 together with the terminal type and service type. The communication system 179 does nothing if the authentication content is the latest, but the terminal 140 has no authentication content, or the authentication content possessed by the authentication content distribution system 159 is changed to the authentication content possessed by the terminal 140. If it has been updated, the latest authentication content is transmitted to the terminal 140.

  Alternatively, the authentication content distribution system 159 may change the stored program main body or a part of the stored program main body, or change the encryption key. The terminal type and service type to be used are determined and notified to the communication system 179. Receiving the notification, the communication system 179 determines the terminal ID from the notified information, and establishes communication between the authentication content distribution system 159 and the terminal 140 corresponding to the determined terminal ID. Whether the authentication content distribution system 159 notifies the terminal 140 corresponding to the determined terminal ID that the content of the authentication content has been changed, or transmits the substance of the changed content to the terminal 140 Alternatively, the changed content is transmitted to the terminal 140 and the old content is updated to the new one.

  The terminal 140 stores the encryption key and content downloaded from the authentication content distribution system 159 in the memory 148. When the operator of the terminal 140 operates the operation device 144 or sends an instruction to the processing device 149 via an input / output device (not shown) in the terminal 140, the processing device 149 stores the program in the memory 148. Execute.

The program gives an instruction to the optical system 146 and receiver 147, photographed or imaged random pattern images I _R and code X. At this time, the operator of the terminal 140 may give the processing device 149 the timing of photographing or imaging through the operation device 144 after adjusting the relative positions of the image receiver 147 and the optical system 146 and the forgery prevention medium 100. . These adjustments and timings may be automatically performed by a not-shown transporter or positioner. Some of the authentication content downloaded to the terminal 140, contains the processes of the digital information of the random pattern image I _R described above in conjunction with the description of FIG. 8.

An example of processing when the public key cryptosystem is used in the information conversion A will be described. Authentication content downloaded to the terminal 140, a digital information of a random pattern image I _R based on the photographed or captured image. On the other hand, the downloaded content for authentication decrypts the code X using the public key. The composite information is, filled with information digitized random pattern image I _R. If these two values are compared and they match, it is determined that the anti-counterfeit medium 100 is valid and the article 101 to which the medium is fixed is also valid (hereinafter, judgment of validity). In addition to the determination being made in the processor 149, the processor 149 sends an instruction to the display 145 or the sound generator 142 to generate a display or sound depending on the content of the determination, It includes a process of operating a vibrator or the like provided in the terminal 140 (not shown) to generate a physical movement in the terminal 140 or transmitting a determination result to the outside through the communication device 143). The reason for seeing such a match is that the process described above with reference to FIG. 8 is limited to the case where a valid private key is used for information conversion A.

  An example of processing when the common key cryptosystem is used in the information conversion A will be described. The common key is used for what has been described as the encryption key so far, including the encryption key 153. In this case, this key is typically not disclosed. Since the common key downloaded to the terminal is provided to an authenticated information provider and has undergone an authenticated communication route, the key is concealed with a certain degree of reliability. The code 140 is decrypted by the terminal 140 using the common key, and the same legitimacy determination as before is performed. This is because, as described above, only when the secret key that is concealed in the information conversion A is used, the coincidence of the results is seen.

An example of processing when the reversible conversion method (and equivalent conversion) is used in the information conversion A will be described. Regardless of whether the encryption key or conversion logic is published, if the random pattern image I _R image with non-uniqueness replication, it is possible to determine the validity. For example, like the case where the random pattern image I digitized information feature point extraction results for the _R is in the code X, the feature point extraction result of the digital information of the random pattern image I _R taken or captured by the terminal 140 and , if a feature point extraction result code X match, it is possible random pattern image I _R copying impossibility and uniqueness same validity determining the grounds.

An example of processing when the irreversible conversion method is used in information conversion A will be described. In this case, it is impossible to decode the feature information of the random pattern image I _R is the code X. Also, if the terminal 140 shown in FIG. 9 does not know the contents of the auxiliary information generator 136 and the memory 137 shown in FIG. It can not also generate code X from the pattern image I _R. Therefore, the terminal 140 can be obtained by not using the auxiliary information generator 136 and the memory 137 shown in FIG. 8, or by making the values held by them public, or by registering the values in the authentication content distribution system 159. To. In addition, information regarding these values may be given to a portion that does not receive the information conversion A of the code X. In this case, regardless of whether or not the encryption key or conversion logic is published, if the random pattern image I _R image with non-uniqueness replication, it is possible to determine the validity. For example, like the case where the random pattern image I digitized information feature point extraction results for the _R is in the code X, the feature point extraction result of the digital information of the random pattern image I _R taken or captured by the terminal 140 and , if a feature point extraction result code X match, it is possible random pattern image I _R copying impossibility and uniqueness same validity determining the grounds.

  When the terminal 140 transmits the result of confirmation of the validity of the terminal 140 to the outside of the terminal, it is transmitted to the stakeholder of the article 101 (manufacturer, administrator, supervisor, business operator, supervisory ministry, audit corporation, etc.) There are cases. It may be transmitted regardless of the result, or may be transmitted only when an anti-counterfeit medium 100 whose validity is not confirmed or an article 101 on which the anti-counterfeit medium 100 is fixed is found. As a result, the stakeholder can know the forgery occurrence state of the forgery prevention medium 100 and the article 101. When the result of the article 101 whose validity cannot be confirmed is sent to the stakeholder, the stakeholder can know the generation time, location, frequency, etc. of the unauthorized article 101 from the transmission history of the terminal 140. By using such information, it is possible to analyze and deal with the cause of illegal goods 101 more effectively than when there is no such information (for example, to the appropriate place or region at the appropriate time) Investigation of the distribution process in which the article 101 is distributed and improvement of the distribution process according to the result). As a result, there is an effect that the occurrence of 101 in which the validity cannot be confirmed can be effectively suppressed by the accuracy confirmation and the information distribution while overcoming problems such as focusing and the like.

  The authentication content, encryption key, and service type held by the terminal 140 are not limited to one set. Depending on the contract between the operator of the communication system 179 and the contractor of the terminal 140, the user of the terminal 140 may use a plurality of types of services. As an example, consider a case where an authentication algorithm differs depending on the type of the article 101. For example, it is assumed that one of the articles 101 is a banknote and a public key cryptosystem is used for the authentication algorithm. In addition, it is assumed that another item is a gift certificate and uses a common key cryptosystem. Further, another one of the articles is a lottery ticket, and a symmetric transformation method is used. Furthermore, it is assumed that the authentication content and encryption key used in the terminal 140 corresponding to each type of article 101 are different.

  The terminal 140 reads the code X, and the terminal 140 acquires service type information from a portion other than the portion that has received the information conversion A. The terminal 140 transmits the service type information to the communication system 179. The communication system 179 checks whether there is a service contract corresponding to the service type. If there is no service contract, the communication system 179 transmits a message to that effect to the terminal 140 to that effect. When there is a contract, the connection between the authentication content distribution system 159 corresponding to the service type and the terminal 140 is established, and the authentication content distribution system 159 checks the presence / absence of the authenticated content of the terminal 140, the version check, and if necessary. Then, the latest authentication content is transmitted to the terminal 140. The terminal 140 has authentication content corresponding to a plurality of required service types. By executing the legitimacy determination process corresponding to the read service type on the terminal 140, the forgery prevention medium 100 of different service types and the article 101 to which the service type is fixed can be seamlessly verified. Judgment is possible.

The terminal 140, for example, using a cellular phone or a portable terminal, if a camera function to those (corresponding to the optical system 146 and the receiver 147) is supplied with, be taken random data image I _R by using the camera function Conceivable. In this case, typically, since these terminals are operated by hand, the relative positions of the terminal 140 and the anti-counterfeit medium 100 cannot be accurately fixed during shooting by shaking or shaking. In such a case, the task of focusing on execution of the authenticity determination process is more serious, and as a result, it is possible to configure the terminal 140 that can perform the authenticity determination process quickly and accurately. There is a problem that it is difficult or operation of the terminal 140 becomes difficult. On the other hand, when the terminal 140 described here is used together with the forgery prevention medium 100, there is an effect that a problem such as focusing can be solved and a highly accurate determination can be made promptly.

  Further, if the authentication content corresponding to the service type for determining the legitimacy of the forgery prevention medium 100 is stored in the memory 148, the legitimacy of the article 101 can be determined by the terminal 140 alone (in the determination itself, the communication system 179). Therefore, even if the communication environment is bad or there is no communication environment, the terminal 140 is constructed that can always determine correctness while minimizing the effort of focusing etc. There is an effect that can be done. The authentication content stored in the memory 148 is used together with the authentication content distribution system 159, so that the authentication method of the terminal 140 is always kept up-to-date, so that it is possible to determine the validity with higher accuracy. There is an effect that the terminal 140 can be constructed.

  By providing the code X having the contents described with reference to FIGS. 8 and 9 on the anti-counterfeit medium 100 or the article 101, it is possible to perform authentication suitable for confirming the validity by the code X while minimizing the trouble of focusing and the like. There is an effect that an anti-counterfeit medium 100 that includes a service type that can identify the content distribution system 159 and can always determine correctness or an article 101 to which the anti-counterfeit medium 100 is fixed can be constructed.

In the previous discussion of FIG. 9, the terminal 140 shows an example in which the determination of the validity by using the random data image I _R and code X. However, if the processor 149 in the terminal 140 does not need to be overloaded with information processing, or if it is desired to increase the accuracy of confirmation further than the confirmation of validity in the above description, the authentication system 189 is used. May be used. Hereinafter, this case will be described. In the future, in the description that has been described so far, it is “local authentication” that the part 140 for verifying the validity locally in the terminal 140 (ie, the validity is confirmed), and the authentication system described below. The confirmation of validity using 189 is referred to as “center authentication”.

Similarly to the local authentication, the terminal 140 captures or captures the random pattern image I _R , the code X, and the code E of the forgery prevention medium 100 and the article 101. These are converted into digital data by the content provided from the authentication content distribution system 159. In the local authentication, the validity is confirmed using these data, but in the center authentication, these data are transmitted from the terminal 140 to the authentication system 189 through the communication system 179.

  In order to cause such a difference in processing between the local authentication and the center authentication, the selection of the user of the terminal 140 to perform the local authentication or the center authentication is stored in the memory 148 and the authentication is executed. In the authentication program, a process for referring to this content and a process for prompting the user of the terminal 140 to select whether to perform local authentication or center authentication in the middle of executing the authentication content are provided in the authentication program.

  Regarding the confirmation of whether or not the terminal 140 can use the service of the authentication system 189, the contract regarding the use, the method of establishing the connection when the terminal 140 can be used, the charge and the cost burden, etc., the above-described terminal 140 and the content distribution system for authentication 159 It is the same as the description regarding the connection between the two.

The database 182 in the authentication system 189 stores information obtained when the anti-counterfeit medium 100 and the article 101 are manufactured and / or processed as described with reference to FIG. As shown in FIG. 9, the digital data about the random pattern image I _R , code X, and code E sent from the terminal 140 is compared with the information stored in the database 182, and the matching data is registered. For example, the authentication system 189 notifies the terminal 140 that the validity is confirmed or the validity is not confirmed if there is no match. Also, the code E and search code, information of the random pattern image I _R corresponding to the code E (and the hash value of information for authentication of the information) to verify the validity by comparing the or code X Do. The authentication system 189 notifies the terminal 140 of the fact that the validity is confirmed if a match is registered, or the validity is not confirmed if there is no match. The terminal 140 that has received the notification performs the same operation as the local authentication.

  In the case of center authentication, in addition to the problem in local authentication and the effect of solving it, the processor 149 in the terminal 140 requires a load necessary for local authentication (for example, the load on the CPU of the processor 149 in executing the authentication content). There is an effect that authentication can be performed with high accuracy at a lower load than the load of memory resources and the like. The processing device 180 can increase the accuracy of authentication by using a logic that requires more complicated processing for the information conversion A on the premise that it can withstand a higher load than the terminal 140.

  Such a low load on the terminal 140 means that the battery capacity and calculation capability of the terminal 140 do not have to be a problem, and it also has the effect of reducing the size and weight of the terminal 140 and saving power. When the terminal 140 is a mobile phone or a mobile terminal, the terminal 140 can be reduced in size and weight, which has an effect of reducing the difficulty in focusing and positioning during shooting or imaging described above. That is, in addition to the problems and effects described in the local authentication, there is an effect that a more accurate authentication system 189 can be constructed without taking time and effort for focusing.

  In addition to the problems and effects described so far for the terminal 140, there is an effect that the terminal 140 that realizes a highly convenient service by seamlessly integrating local authentication and center authentication can be constructed.

  When the authentication system 189 is used, the status information described using FIG. 8 and the status information accompanying the inquiry of the terminal 140 shown in FIG. 10 may be registered in the table 184. For example, information such as the following (a) to (f) and its history may be recorded for each article.

(A) Where (installation location of the registration device 130, communication location of the terminal 140, installation location of the confirmation device 190 described later, etc.)
(B) When (inquiry service occurrence time and answer time)
(C) From whom (ID of the terminal 140 shown in FIG. 9, ID of the authentication content of the processor 149, ID of the confirmation device 190 described later, ID of the program of the processing unit 191, etc.)
(D) What (service inquiry content and response content, etc.)
(E) How (how processing was done to make a decision on confirmation of legitimacy, etc.)
(F) To whom (providing authentication service, etc.)
Such information and its history may be useful for confirming validity. For example, the validity of the same article 101 has been confirmed a plurality of times, but the distance between the places where the confirmation request is made is significantly larger than the time difference between the validity confirmations. In such a case, it may be considered that the article 101 has been counterfeited because the article 101 cannot be moved. In this case, in addition to the problems and effects described so far, there is an effect of further improving the accuracy of confirmation of validity.

In FIG. 10, a confirmation device 190 includes an image receiver 192 combined with an optical system 193, an image receiver 194 combined with an optical system 195, a service type 196 (a memory storing information about the service type and an abbreviation of the information itself). ), Service authorization condition 197 (memory storing information about the service authorization condition and abbreviation of the information itself), an operation device 198, a display device 199, a sound generation device 200, and a processing unit 191 coupled thereto.

  As shown in FIG. 10, the confirmation system 210 includes a confirmation machine 190, a database 212 and a database 213 connected to the processing unit 191, a stacker 201 connected to the processing unit 191, a conveyance / positioning device 202, a flapper gate 203, a conveyance The apparatus 204 includes a transport device 205, a stacker 206, and a stacker 207. Note that the stacker here refers to the necessary number of articles 101 (typically one by one) that stores one or a plurality of articles 101 supplied from the outside and stores them in response to an external signal. Refers to equipment that is taken out and provided to the outside.

  The processing unit 191 includes a CPU, a memory, a program on the memory, information on the memory necessary for executing the program, an input / output device, a display device, a power supply, and the like.

  One or a plurality of articles 101 to which the anti-counterfeit medium 100 is fixed are stored in the stacker 201 by being carried in from the outside by an operator of the confirmation system 210 or by a conveyance device (not shown).

The anti-counterfeit medium 100 is fixed by an instruction from the processing unit 191 (specifically, an electric signal output from the processing unit 191 via the input / output device through the program sequence by the CPU executing the program on the memory). The article 101 is taken out from the stacker 201, and the conveyance / positioning device 202 operates according to an instruction from the processing unit 191, and the article 101 taken out from the stacker 201 is conveyed and positioned. The purpose of positioning the code X, code E and a random pattern image I _R is, the method comprising the manner suitable for photographing or imaging by receiver 194 through an optical system 195, the window portion 18 (or, P section) or through-holes 18 The feature amount of the article 101 observed from the ′ (or P part) is suitable for being photographed or photographed by the receiver 192 through the optical system 193. Therefore, for positioning, the position adjustment of the article 101, the position adjustment of each of the optical system 193, the optical system 195, the image receiver 192, and the image receiver 194, and the position adjustment of the part in which the optical system 193 and the image receiver 192 are integrated. , And position adjustment of a part in which the optical system 195 and the receiver 194 are integrated.

  Using the procedure described later, the validity of the anti-counterfeit medium 100 and the article 101 to which the forgery prevention medium 100 is fixed is confirmed, and the result is processed into a processing unit 191 (specifically, a specific memory area managed by a program in the processing unit 191) ) Wins.

  The position of the flapper gate 203 changes according to the instruction of the processing unit 191 according to the result of the validity, and all the articles 101 whose validity has been confirmed are stored in the stacker 206 through the transport device 204. The articles 101 whose validity is not confirmed are all stored in the stacker 207 through the transport device 205. Here, two types of flapper positions have been described. However, further classification can be performed by providing the number of flapper positions and a corresponding conveyor or stacker.

  For example, the position of the flapper is classified into three types: a case where the validity is confirmed, a case where the validity is denied, and a case where the validity is difficult or unclear. In this case, the stakeholder of the article 101 needs to be urgently investigated and / or dealt with the above-mentioned counterfeit because the authenticity of the stakeholder may be counterfeited. When it is difficult or unclear to determine the legitimacy, typically, the anti-counterfeit medium 100 is soiled or damaged, and the stakeholder of the article 101 confirms the validity of the owner of the article 101. However, in this case, it is not necessary for a stakeholder to deal with counterfeiting. By performing such a confirmation system, it is possible to efficiently confirm the validity and quickly respond to the counterfeiting of the article while solving the problem of focusing on the confirmation of the validity of the article 101. In addition, there is an effect that it is possible to construct the confirmation system 210 that can quickly cope with the contamination and damage of the article and the anti-counterfeit medium 100.

Similar to the terminal 140 shown in FIG. 9, the confirmation system 210 has a function of performing local authentication. The authentication content necessary for this is acquired from the authentication content distribution system 159 shown in FIG. At this time, a service identifier 196 and a service permission condition 197 are transmitted to the authentication content distribution system, and the service can be used. Further, the authentication content is provided to the processing unit 191 through the operation device 198 or an input / output device provided in a control unit (not shown in FIG. 10). In this way, the verification system 210, by a combination of the random pattern image I _R and codes X, using the method described above, the validity of the article 101 to the medium for preventing forgery 100 and anti-counterfeit medium 100 is fixed You can check. The display device 199 and the sound generation device 200 may operate depending on the result of confirmation of validity.

Further, by performing an operation like the center authentication described with reference to FIG. 9, the confirmation system 210 shown in FIG. 10 performs center authentication. In this case, the confirmation device 190 is connected to the forgery prevention medium 100 to be verified and the article 101 to which the authenticity is fixed through an online connection such as a network connection or an offline connection by physical transport such as a magnetic tape. X, code E, sends the information digitized characteristics of the random pattern images I _R and articles 101 observed through the window portion 18 or the through-hole 18 'to the authentication system 189. At this time, the confirmation device 190 simultaneously sends the service identifier 196 and the service authorization condition 197, and notifies the authentication system 189 that the service can be used. The authentication system 189 authentication and validity check method are the same as those described above. Results are sent back to the confirmation system 210 online or offline. The authentication system 189 checks the service identifier and the service authorization in order to confirm that the receiving destination is a return from a valid authentication system in the validity confirmation described above or in the confirmation described with reference to FIG. Return the conditions, etc., and inform the inquiry source that they are a valid return source.

  The speed of information communication of the connection between the confirmation system 210 and the authentication system 189 (for example, the amount of information that can be communicated per second) is slow, and the speed of information processed by the confirmation system 210 (for example, the article 101 that can be processed per second) If the number of items 101 that can be processed per second is intentionally reduced, the confirmation system 210 may determine whether the number of items 101 that can be processed per second is intentionally reduced. There is a method in which information to be processed is once cached in the database 212 and the information is communicated to the authentication system 189 by the FIFO method until the free space of the database 212 is exhausted. In the latter case, until the free space of the database 212 is exhausted, the confirmation system 210 can perform a process for confirming the correctness (specifically, a part of the process for that purpose) at the maximum processing speed it can have.

The database 213 connected to the processing unit 191 stores a history regarding the operation of the confirmation system 210 (specifically, a log including the inquiry content to the authentication system 189 and the validity confirmation result). This is used for checking or auditing the operation of the confirmation system 210 or for pursuing the cause when the operation of the confirmation system 210 seems to be defective.

  By constructing the confirmation system 210 as described above, it is possible to obtain an effect of improving the above-described problems such as focusing and the like, and to obtain an efficient and highly accurate confirmation system 210. There is.

  Further, the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.

  Examples of the present invention will be described below.

<Example 1>
(Preparation of anti-counterfeit media and adhesive labels)
First, a diffractive structure forming layer 1 μm is coated on a 50 μm-thick PET film with a urethane resin using a gravure coating method, and then an 80 nm aluminum reflective layer is formed thereon using a vacuum vapor deposition method. An image was formed by embossing to prepare a hologram deposition sheet.

  Subsequently, a polyamideimide resin is formed on the reflective layer in a pattern other than the 10 mm square size R portion and the 1 mm diameter P portion as shown in FIG. 2, and then etched by the R portion of the reflective layer. And P part is removed.

  Next, a random pattern layer is formed by applying a mixture of a white pigment and a cured silicone resin to a gravure plate in which grooves are formed in accordance with the P portion.

  Subsequently, an acrylic resin-based black ink 2 μm is applied on the random pattern layer using a gravure plate in which grooves are similarly formed in accordance with the P portion to form a colored layer.

  After that, polyethylene is laminated on one side of the kraft paper, and an acrylic adhesive is applied to the release sheet (thickness: 112 μm) that has been treated with silicon, and this is transferred to the film to form an adhesive layer. By providing, the adhesive label A of the anti-counterfeit medium was completed.

<Example 2>
(Preparation of anti-counterfeit media, transfer foil)
First, a 1 μm release protective layer was applied to a 19 μm thick PET film with an acrylic resin using a gravure coating method. Thereafter, the diffraction structure forming layer to the colored layer were formed in the same manner as in Example 1. Finally, an anti-counterfeit medium transfer foil B was completed by applying an acrylic resin adhesive of 3 μm and providing an adhesive layer.

  The adhesive label A and the transfer foil B of the anti-counterfeit medium thus obtained were affixed or transferred to the banknote. Since the adhesive label A and the transfer foil B are provided with a window inside the medium body, the printed identification number information, the image information indicated by the random pattern image, and the paper indicated by the paper pattern observed from the window It was possible to carry out the process of associating the pattern information with the time. In addition, since the PET base material or the peeling protective layer is on the medium surface, the change in the shape of the outermost paper surface of the window due to dirt or scratches is suppressed, and stable paper pattern information can be read. Furthermore, if you try to peel off the anti-counterfeit medium pasted on the banknote, the paper top surface shape of the window part will also peel off and change, making it impossible to read the paper pattern information and detect the pasting action Met.
