[0001] The present disclosure relates to anti-counterfeiting packaging, an authenticity determining device, an authenticity determining system, and an authenticity determining method. [Background technology]

[0002] Proposed is an anti-counterfeiting printed material having an identification code that is composed using either multiple types of ink that have different spectral reflectance characteristics to irradiated light or multiple types of ink that have different color development characteristics depending on temperature conditions, in which the ink used to print the identification code is different from the ink used to print an authenticity determination code mixed into the identification code (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-188756 A Summary of the Invention [Problem to be solved by the invention]

[0004] Meanwhile, there is a method for preventing counterfeiting of products and managing product logistics by printing a mixture of an identification code and an authenticity determination code on the surface of a product's packaging, for example, as described in Patent Document 1.

[0009] (Embodiment 1) Hereinafter, a description will be given of an anti-counterfeiting package and an authenticity determination system according to the present embodiment with reference to the drawings. The anti-counterfeiting package according to the present embodiment is a package for packaging a product and preventing the product from being counterfeited. This anti-counterfeiting package includes a first code printed with a first ink containing a substance that absorbs light in a wavelength band other than the ultraviolet light band and emits light in a wavelength band in the visible light band at a position that can be seen from the outside of the anti-counterfeiting package only when at least a part of the anti-counterfeiting package is deformed or processed, and a second code printed with a second ink containing a substance that selectively absorbs or emits light in a wavelength band of visible light at a position that can be seen from the outside of the anti-counterfeiting package without deforming or processing at least a part of the anti-counterfeiting package.

[0010] 1, the authenticity determination system according to this embodiment includes an authenticity determination device 1A owned by a manufacturer of a product PR, an authenticity determination device 1B owned by a retailer who retails the product PR or a customer of the product PR, and a cloud server 2. The product PR is contained in a packaging container PA and arrives at the retailer from its manufacturer via multiple wholesalers. The authenticity determination device 1 and the cloud server 2 are capable of communicating with each other via a network NW1.

[0011] The packaging container PA is a counterfeit prevention package having a rectangular box shape, for example, as shown in Fig. 2 and Fig. 3, four rectangular sheet-like side walls PAa, PAb, PAe, PAf, and two rectangular sheet-like lids PAc, PAd that cover both ends of the area surrounded by the four side walls PAa, PAb, PAe, PAf. Here, as shown in Fig. 3, the packaging container PA is arranged so that the side walls PAa, PAb, PAe, PAf are aligned along the respective short sides of the packaging container PA in the unfolded state. The lid PAc extends from one end of the side wall PAa in the longitudinal direction, and the tongue piece PAh is continuous with the end of the lid PAc opposite to the side wall PAa side. The lid PAd extends from one end of the side wall PAb in the longitudinal direction, and the tongue piece PAi is continuous with the end of the lid PAd opposite to the side wall PAb side. The tongue pieces PAj are continuous with both ends of the side wall PAe in the longitudinal direction, and the tongue pieces PAk are continuous with both ends of the side wall PAf in the longitudinal direction. Also, the tongue piece PAg is continuous with the end of the side wall PAb opposite to the side wall PAf in the lateral direction, which will be a margin when the side walls PAa, PAb, PAe, and PAf are assembled into a rectangular tube.

[0012] As shown in Fig. 2 and Fig. 3, a QR code (registered trademark) C2 is printed on the side wall PAb of the packaging container PA, and a two-dimensional code C1 is printed on the tongue piece PAg. The two-dimensional code C1 is a first code printed with a first ink containing an ultraviolet light-emitting phosphor that is difficult to see under light in the visible wavelength range. This first ink has a property that the phosphor contained therein fluoresces when irradiated with ultraviolet light. The ultraviolet light-emitting phosphor is one that is excited by ultraviolet light and emits a spectrum peak in the visible wavelength range when it returns to a lower energy level, such as Ca2B5O9Cl:Eu 2+ ,CaWO4,ZnO:Zn2SiO4Mn,Y2O2S:Eu,ZnS:Ag,YVO4:Eu,Y2O3:Eu,Gd2O2S:Tb,La2O2S:Tb,Y3Al5O 12 :Ce, etc. The QR code C2 is a second code printed, for example, with a normal black second ink. The two-dimensional code C1 is printed on a tongue piece PAg that can be seen from the outside of the packaging container PA only when at least a part of the packaging container PA is deformed or processed, i.e., when it is unfolded. The QR code C2 is printed on the outer wall of the side wall PAd when the packaging container PA is not deformed or processed, i.e., when it is assembled into a rectangular box shape.

[0013] This authenticity determination system is used together with terminal devices 3A, 3B, 3C, and 3D owned by, for example, a manufacturer, a wholesaler, and a retailer. Each of the terminal devices 3A, 3B, 3C, and 3D is, for example, a smartphone equipped with a camera, and has a function of identifying product identification information of the product PR obtained by analyzing a QR code image obtained by capturing an image of a QR code C2 printed on a side wall PAb of a packaging container PA, and a function of generating and transmitting to the cloud server 2 logistics history notification information including the identified product identification information and logistics history information indicating the history of the product PR.

[0014] The cloud server 2 functions as a management server that manages information for judging the authenticity of the product PR, and includes a distribution history storage unit (not shown) that stores distribution history information of the product PR, and a criterion information storage unit (not shown) that stores criterion information used for judging the authenticity of the product PR in association with product identification information. When the cloud server 2 acquires distribution history notification information transmitted from the terminal devices 3A, 3B, 3C, and 3D, it extracts the product identification information and distribution history information contained in the acquired distribution history notification information, and stores the extracted product identification information and distribution history information in association with each other in the distribution history storage unit. When the cloud server 2 acquires criterion notification information including criterion information and product identification information transmitted from the authenticity judgment device 1 (1A), it extracts the criterion information and product identification information contained in the acquired criterion notification information, and stores the extracted criterion information and product identification information in association with each other in the criterion information storage unit.

[0015] The authenticity determination device 1 operates in one of two operation modes: a product registration mode for registering a packaging container PA containing a product PR in the cloud server 2, and an authenticity determination mode for determining the authenticity of the product PR. As shown in FIG. 4, the authenticity determination device 1 includes a CPU (Central Processing Unit) 101, a main memory unit 102, an auxiliary memory unit 103, a display unit 104, an input unit 105, a communication unit 106, an imaging unit 151, an ultraviolet light source 107, and a bus 109 connecting each unit. The main memory unit 102 is a volatile memory such as a RAM (Random Access Memory) and is used as a working area for the CPU 101. The auxiliary memory unit 103 is a non-volatile memory such as a semiconductor flash memory and stores programs for realizing various functions of the authenticity determination device 1. The display unit 104 is a liquid crystal display, an organic EL (Electro-luminescence) display, or the like, and displays various information. The input unit 105 is, for example, a touch pad placed on the display unit 104, and receives various operation information according to user operations and outputs the received operation information to the CPU 101. The communication unit 106 has an interface for connecting to the network NW1. The imaging unit 151 has a camera and transfers image information obtained by capturing an image of the two-dimensional code C1 and the QR code C2 to the CPU 101. The ultraviolet light source 107 has, for example, an LED (Light Emittng Diode) that emits ultraviolet light, and lights up the LED based on control information transferred from the CPU 101.

[0016] The CPU 101 reads out the program stored in the auxiliary storage unit 103 into the main storage unit 102 and executes it, thereby functioning as a reception unit 111, an imaging control unit 112, a display control unit 113, a code analysis unit 114, a light source control unit 115, a criterion information notification unit 116, a criterion information acquisition unit 117, and an authenticity determination unit 118, as shown in FIG. 5. The auxiliary storage unit 103 shown in FIG. 4 also has a determination information storage unit 131, as shown in FIG. 5. The main storage unit 102 shown in FIG. 4 also has an image buffer 121 that temporarily stores an image captured by the imaging unit 151, as shown in FIG. 5. The determination information storage unit 131 stores a two-dimensional code image obtained by capturing an image of the two-dimensional code C1 and the QR code C2, determination information obtained by analyzing the QR code image, and product identification information.

[0017] The reception unit 111 receives the operation contents performed by the user on the input unit 105, generates operation information according to the received operation contents, and notifies the imaging control unit 112, the display control unit 113, the code analysis unit 114, the light source control unit 115, the judgment criterion information notification unit 116, and the judgment criterion information acquisition unit 117. When the reception unit 111 receives a product registration operation for reading the two-dimensional code C1 or the QR code C2 and a product history confirmation operation, the imaging control unit 112 controls the imaging unit 151 to perform imaging processing. At this time, the imaging unit 151 transfers captured image information obtained by the imaging processing to the image buffer 121. The display control unit 113 causes the captured image information stored in the image buffer 121 to be displayed on the display unit 104. In addition, when the display control unit 113 is notified of information indicating a judgment result described later from the authenticity judgment unit 118, it forms a result notification image notifying the judgment result based on the notified information and causes the display unit 104 to display it.

[0018] After the reception unit 111 receives the above-mentioned product registration operation and product history confirmation operation, the code analysis unit 114 extracts a two-dimensional code image and a QR code image from the captured image indicated by the captured image information newly stored in the image buffer 121. Here, the code analysis unit 114 extracts the two-dimensional code image and the QR code image using an edge detection method for the two-dimensional code image and the QR code image, such as a graph cut method. Then, the code analysis unit 114 analyzes the extracted two-dimensional code image and the QR code image to identify the judgment criterion information or judgment information and the product identification information corresponding to the two-dimensional code image and the QR code image, and stores the identified judgment criterion information or judgment information and the product identification information in the judgment information storage unit 131.

[0019] When the reception unit 111 receives an operation for reading the two-dimensional code C1 in the above-mentioned product registration operation or product history confirmation operation, the light source control unit 115 turns on the ultraviolet light source 107. On the other hand, when the reception unit 111 receives an operation for reading the QR code C2 in the above-mentioned product registration operation or product history confirmation operation, the light source control unit 115 turns off the ultraviolet light source 107.

[0020] When new criterion information and product identification information are stored in the information for judgment storage unit 131 after the reception unit 111 receives the above-mentioned product registration operation, the criterion information notification unit 116 generates criterion notification information including the criterion information and product identification information stored in the information for judgment storage unit 131 and transmits it to the cloud server 2. When the reception unit 111 receives the above-mentioned product history confirmation operation, the criterion information acquisition unit 117 generates criterion request information including the product identification information stored in the information for judgment storage unit 131 and transmits it to the cloud server 2, thereby acquiring the criterion information transmitted from the cloud server 2. The criterion information acquisition unit 117 stores the acquired criterion information in the criterion information storage unit 132.

[0021] The authenticity determination unit 118 performs authenticity determination of the product PR based on the determination information stored in the determination information storage unit 131 and the determination criterion information stored in the determination criterion information storage unit 132. Specifically, the authenticity determination unit 118 determines whether or not a numerical value indicated by the determination information matches a numerical value indicated by the determination criterion information, and if they match, determines that the product PR is genuine, and if they differ, determines that the product PR is a counterfeit. The authenticity determination unit 118 notifies the display control unit 113 of information indicating the determination result.

[0022] Next, an example of a target of use of the authenticity determination system according to the present embodiment will be described. First, as shown in FIG. 1, at the manufacturer, an authenticity determination device 1A is used to capture an image of a two-dimensional code C1 printed on a packaging container PA in an unfolded state, and a first code image of the two-dimensional code obtained by capturing the image is analyzed to identify criteria information that is a criterion for authenticity determination of the product PR indicated by the first code image. Also, an authenticity determination device 1 is used to capture an image of a QR code C2 printed on a packaging container PA in an unfolded state, and a second code image of the QR code obtained by capturing the image is analyzed to identify product identification information that identifies the product PR indicated by the second code image. Then, the authenticity determination device 1A transmits the identified criteria information and product identification information to the cloud server 2. Next, at the manufacturer, the product PR is placed inside the packaging container PA assembled into a rectangular box shape, and then the QR code C2 is captured using a terminal device 3A. Then, the terminal device 3A transmits the product identification information obtained by analyzing the captured QR code image to the cloud server 2 together with logistics history information such as shipping date and time. Next, the packaging container PA containing the product PR is shipped to a wholesaler of the product PR. Then, at each wholesaler, the QR code C2 is captured using the terminal devices 3B and 3C. At this time, the terminal devices 3B and 3C transmit the product identification information obtained by analyzing the captured QR code image to the cloud server 2 together with the logistics history information such as the arrival date and time. Then, when the packaging container PA arrives at the retailer, the retailer captures the QR code C2 using the terminal device 3D. At this time, the terminal device 3D transmits the product identification information obtained by analyzing the captured QR code image to the cloud server 2 together with the logistics history information such as the arrival date and time. Next, the customer of the product PR unfolds the packaging container PA, and then uses the authenticity determination device 1B to capture the two-dimensional code C1 printed on the unfolded packaging container PA, and analyzes the first code image of the captured two-dimensional code to identify the determination information for authenticity determination of the product PR indicated by the first code image. In addition, the authenticity determination device 1B is used to capture an image of the QR code C2 printed on the packaging container PA in an unfolded state, and the second code image of the QR code obtained by capturing the image is analyzed to determine product identification information that identifies the product PR indicated by the second code image.Then, the authenticity determination device 1B acquires the judgment criteria information managed by the cloud server 2, and then executes the authenticity determination of the product PR based on the acquired judgment criteria information and the specified judgment information, and displays the judgment result. In this way, the customer of the product PR can confirm the authenticity of the product PR by using the authenticity determination device 1B.

[0023] Next, the operation of the authenticity determination system according to the present embodiment will be described with reference to FIG. 6. First, when a mode setting operation for setting the operation mode of the authenticity determination device 1A to the product registration mode is performed at the manufacturer, the operation mode of the authenticity determination device 1A is set to the product registration mode (step S1). Next, it is assumed that the manufacturer performs a product registration operation on the authenticity determination device 1A. In this product registration operation, an operation is performed to sequentially capture images of the two-dimensional code C1 and the QR code C2 of the packaging container PA in the unfolded state. In this case, the authenticity determination device 1A captures an image of the two-dimensional code C1 of the packaging container PA with the ultraviolet light source 107 turned on, and captures an image of the QR code C2 with the ultraviolet light source 107 turned off (step S2). Here, the authenticity determination device 1A stores captured image information indicating the captured images obtained by capturing the two-dimensional code and the QR code in the image buffer 121.

[0024] Next, the authenticity determination device 1A extracts a two-dimensional code image and a QR code image from the captured image indicated by the captured image information stored in the image buffer 121, and analyzes the extracted two-dimensional code image and QR code image to identify the judgment criterion information and the product identification information corresponding to the two-dimensional code image and the QR code image. Then, the authenticity determination device 1A stores the identified judgment criterion information and the product identification information in the judgment information storage unit 131 (step S3). After that, the authenticity determination device 1A generates judgment criterion notification information including the judgment criterion information and the product identification information stored in the judgment information storage unit 131 (step S4), and the generated judgment criterion notification information is transmitted from the authenticity determination device 1A to the cloud server 2 (step S5).

[0025] On the other hand, when the cloud server 2 acquires the judgment criterion notification information transmitted from the authenticity determination device 1 (1A), it extracts the judgment criterion information and product identification information contained in the acquired judgment criterion notification information, and stores the extracted judgment criterion information and product identification information in the judgment criterion information storage unit in association with each other (step S6).

[0026] Next, assume that a history registration operation for registering the logistics history of the product PR is performed on the terminal device 3 at the manufacturer, wholesaler, and retailer. In this history registration operation, an operation for capturing an image of the QR code C2 printed on the side wall PAb of the packaging container PA is performed using the terminal devices 3B and 3C. In this case, the terminal device 3 identifies the product identification information of the product PR obtained by analyzing the QR code image obtained by capturing the QR code C2, and generates logistics history notification information including the identified product identification information and logistics history information indicating the history of the product PR (step S7). Next, the generated logistics history notification information is transmitted from the terminal device 3 to the cloud server 2 (step S8). On the other hand, when the cloud server 2 acquires the logistics history notification information transmitted from the terminal device 3, it extracts the product identification information and the logistics history information included in the acquired logistics history notification information, and stores the extracted product identification information and the logistics history information in association with each other (step S9).

[0027] Thereafter, when the customer who purchased the product PR performs a mode setting operation for setting the operation mode of the authenticity determination device 1B to the authenticity determination mode, the operation mode of the authenticity determination device 1B is set to the authenticity determination mode (step S10). Next, it is assumed that the customer performs a product history confirmation operation on the authenticity determination device 1B. In this product history confirmation operation, an operation is performed to sequentially capture images of the two-dimensional code C1 and the QR code C2 of the packaging container PA in the unfolded state. In this case, the authenticity determination device 1B captures an image of the two-dimensional code C1 of the packaging container PA with the ultraviolet light source 107 turned on, and captures an image of the QR code C2 with the ultraviolet light source 107 turned off (step S11). Here, the authenticity determination device 1B stores captured image information indicating the captured images obtained by capturing the two-dimensional code and the QR code in the image buffer 121.

[0028] Next, the authenticity determination device 1B extracts a two-dimensional code image and a QR code image from the captured image indicated by the captured image information stored in the image buffer 121, and analyzes the extracted two-dimensional code image and QR code image to identify determination information and product identification information corresponding to the two-dimensional code image and the QR code image. Then, the authenticity determination device 1B stores the identified determination information and product identification information in the determination information storage unit 131 (step S12). After that, the authenticity determination device 1B generates determination criterion request information including the product identification information stored in the determination information storage unit 131 (step S13), and the generated determination criterion request information is transmitted from the authenticity determination device 1B to the cloud server 2 (step S14).

[0029] On the other hand, when the cloud server 2 acquires the criterion request information, it identifies the criterion information corresponding to the product identification information included in the acquired criterion request information from the criterion information stored in the criterion information storage unit (step S15). Next, the identified criterion information is transmitted from the cloud server 2 to the authenticity determination device 1B (step S16). On the other hand, when the authenticity determination device 1B acquires the criterion information, it stores the acquired criterion information in the criterion information storage unit 132 (step S17). Next, the authenticity determination device 1B performs the authenticity determination of the product PR based on the information for determination stored in the information for determination storage unit 131 and the criterion information stored in the criterion information storage unit 132 (step S18). After that, the authenticity determination device 1B forms a result notification image showing the result of the authenticity determination and displays it on the display unit 104 (step S19).

[0030] Next, the authenticity determination process executed by the authenticity determination device 1 according to the present embodiment will be described with reference to FIG. 7. This authenticity determination process is started when the authenticity determination device 1 is powered on. First, the reception unit 111 judges whether or not the above-mentioned mode setting operation performed on the input unit 105 has been received (step S101). Here, as long as the reception unit 111 judges that the mode setting operation has not been received (step S101: No), the process of step S101 is repeatedly executed. On the other hand, when the reception unit 111 judges that the mode setting operation has been received (step S101: Yes), it judges whether or not the above-mentioned product registration mode has been set (step S102). Here, when the reception unit 111 judges that the above-mentioned authenticity determination mode has been set (step S102: No), the process of step S107 described later is executed. On the other hand, when the reception unit 111 determines that the product registration mode is set (step S102: Yes), it determines whether or not the above-mentioned product registration operation has been received (step S103). Here, when the reception unit 111 determines that the product registration operation has not been received within a preset period (step S103: No), the process of step S101 is executed again. On the other hand, when the reception unit 111 determines that the product registration operation has been received (step S103: Yes), the light source control unit 115 turns on or off the ultraviolet light source 107, and the imaging control unit 112 controls the imaging unit 151 to capture the two-dimensional code C1 or the QR code (step S104). Here, when the reception unit 111 receives an operation for reading the two-dimensional code C1 in the above-mentioned product registration operation, the light source control unit 115 turns on the ultraviolet light source 107, and the imaging control unit 112 controls the imaging unit 151 to capture the two-dimensional code C1. On the other hand, when the reception unit 111 receives an operation for reading the QR code C2 in the above-mentioned product registration operation, the light source control unit 115 turns off the ultraviolet light source 107, and the imaging control unit 112 controls the imaging unit 151 to capture the QR code C2. At this time, the imaging unit 151 transfers captured image information obtained by the imaging process to the image buffer 121.

[0031] Next, the code analysis unit 114 extracts a two-dimensional code image and a QR code image from the captured image indicated by the captured image information newly stored in the image buffer 121. Then, the code analysis unit 114 analyzes the extracted two-dimensional code image and QR code image to identify criterion information or information for judgment corresponding to the two-dimensional code image and the QR code image, and stores the identified criterion information in the information for judgment storage unit 131 (step S105). Next, the criterion information notification unit 116 generates criterion notification information including the criterion information stored in the information for judgment storage unit 131, and transmits it to the cloud server 2 (step S106). After that, the process of step S101 is executed again.

[0032] In addition, when the reception unit 111 determines in step S102 that the above-mentioned authenticity determination mode has been set (step S102: No) or that the product registration mode has been set (step S102: Yes), it determines whether or not the above-mentioned product history confirmation operation has been accepted (step S107). Here, when the reception unit 111 determines that the product history confirmation operation has not been accepted within a preset period (step S107: No), the process of step S101 is executed again. On the other hand, when the reception unit 111 determines that the product history confirmation operation has been accepted (step S107: Yes), the light source control unit 115 turns on or off the ultraviolet light source 107, and the imaging control unit 112 controls the imaging unit 151 to capture the two-dimensional code C1 or the QR code (step S108). Here, when the reception unit 111 receives an operation for reading the two-dimensional code C1 in the above-mentioned product history confirmation operation, the light source control unit 115 turns on the ultraviolet light source 107, and the imaging control unit 112 controls the imaging unit 151 to capture the two-dimensional code C1. On the other hand, when the reception unit 111 receives an operation for reading the QR code C2 in the above-mentioned product history confirmation operation, the light source control unit 115 turns off the ultraviolet light source 107, and the imaging control unit 112 controls the imaging unit 151 to capture the QR code C2. At this time, the imaging unit 151 transfers captured image information obtained by the imaging process to the image buffer 121.

[0033] Next, the code analysis unit 114 extracts a two-dimensional code image and a QR code image from the captured image indicated by the captured image information newly stored in the image buffer 121. Then, the code analysis unit 114 analyzes the extracted two-dimensional code image and the QR code image to specify the judgment information and the product identification information corresponding to the two-dimensional code image and the QR code image, and stores the specified judgment information and the product identification information in the judgment information storage unit 131 (step S109). Next, the judgment criterion information acquisition unit 117 generates judgment criterion request information including the product identification information stored in the judgment information storage unit 131 and transmits it to the cloud server 2 (step S110), thereby acquiring the judgment criterion information transmitted from the cloud server 2, and stores the acquired judgment criterion information in the judgment criterion information storage unit 132 (step S111).

[0034] Thereafter, the authenticity determination unit 118 performs an authenticity determination of the product PR based on the determination information stored in the determination information storage unit 131 and the determination criterion information stored in the determination criterion information storage unit 132 (step S112). Next, the display control unit 113 forms a result notification image notifying the determination result based on the information indicating the result of the authenticity determination, and displays it on the display unit 104 (step S113). Then, the process of step S101 is executed again.

[0035] As described above, in the packaging container PA according to the present embodiment, a two-dimensional code is printed on the tongue piece PAg, which is visible from the outside of the packaging container PA only when the packaging container PA is in an unfolded state, using a first ink containing a substance that absorbs ultraviolet light and emits light in a wavelength band of visible light. This prevents the two-dimensional code C1 from being read without the end consumer of the product PR noticing during the logistics process of the product PR, since the packaging container PA needs to be in an unfolded state in order to read the contents of the two-dimensional code C1 during the logistics process of the product PR.

[0036] The authenticity determination device 1 according to the present embodiment operates in one of two operation modes, the above-mentioned product registration mode and the authenticity determination mode. This allows the operation mode to be switched depending on the intended use of the manufacturer and the customer, thereby enhancing versatility.

[0037] (Embodiment 2) The authenticity determination system according to the present embodiment differs from that of the first embodiment in that it includes a terminal device that has a function of capturing an image of the first code and the second code of a package on which the first code and the second code described in the first embodiment are printed, and identifying determination information and product identification information corresponding to the first code and the second code, but does not determine the authenticity of the product. In the present embodiment, in addition to the terminal device, it includes determination standard information that indicates a combination of determination information and product identification information corresponding to the first code and the second code printed on the package, respectively, and serves as a standard for determining the authenticity of the product, and an authenticity determination unit that determines the authenticity of the product based on the determination information and determination standard information identified by the terminal device.

[0038] As shown in FIG. 8, the authenticity determination system according to the present embodiment includes a terminal device 2001 owned by, for example, a retailer who retails the product PR or a customer of the product PR, a printer 2004 that prints a QR code C2 and a two-dimensional code C1 on a packaging container PA of the product PR, and a cloud server 2002. In FIG. 8, the same components as those in the first embodiment are denoted by the same reference numerals as those in FIG. 1. The terminal device 2001, the cloud server 2002, and the printer 2004 are capable of communicating with each other via a network NW1. First, a printing company uses the printer 4 to manufacture a packaging container PA on which the QR code C2 and the two-dimensional code C1 are printed. This packaging container PA is, for example, the packaging container PA described in the first embodiment with reference to FIG. 3. Then, as shown in FIG. 8, the printing company supplies the manufactured packaging container PA to, for example, a manufacturer of the product PR. Meanwhile, the manufacturer of the product PR stores the product PR in the packaging container PA. Then, the product PR stored in the packaging container PA arrives from the manufacturer to the retailer.

[0039] 9, the printer 2004 has a printing unit 41 that prints a QR code C2 and a two-dimensional code C1 on a packaging container PA, and a control unit 40. The printing unit 41 executes printing on the packaging container PA based on a control signal input from the control unit 40. The control unit 40 has a print control unit 411, a criterion information notification unit 412, and a print information storage unit 431. The print information storage unit 431 stores multiple types of preset determination information that are the basis of the two-dimensional code C1, and multiple types of preset product identification information that are the basis of the QR code C2.

[0040] The print control unit 411 selects a combination of determination information and product identification information from the determination information and product identification information stored in the print information storage unit 431. Next, the print control unit 411 generates print parameter information for printing the QR code C2 and print parameter information for printing the two-dimensional code C1 based on the selected determination information and product identification information. Then, the print control unit 411 generates control information including the generated print parameter information and outputs it to the printing unit 41. In addition, the print control unit 411 notifies the determination criterion information notification unit 412 of the selected combination of determination information and product identification information.

[0041] The judgment criteria information notification unit 412 generates judgment criteria information indicating a combination of the judgment information and product identification information notified by the print control unit 212, and generates judgment criteria notification information including the generated judgment criteria information and transmits it to the cloud server 2002.

[0042] As shown in Fig. 9, the terminal device 2001 has the same hardware configuration as the authenticity determination device 1 described in the second embodiment. The CPU 101 reads out a program stored in the auxiliary storage unit 103 into the main storage unit 102 and executes it, thereby functioning as a reception unit 111, an imaging control unit 112, a display control unit 113, a code analysis unit 114, a light source control unit 115, a determination request unit 2116, and a determination result acquisition unit 2119, as shown in Fig. 10. In Fig. 9, the same components as those in the first embodiment are denoted by the same reference numerals as those in Fig. 5. In addition, the auxiliary storage unit 103 has a determination information storage unit 131, and the main storage unit 102 has an image buffer 121.

[0043] The reception unit 111 receives the operation contents performed by the user on the input unit 105, generates operation information according to the received operation contents, and notifies the imaging control unit 112, the display control unit 113, the code analysis unit 114, the light source control unit 115, and the judgment request unit 2116. When the reception unit 111 receives a product history confirmation operation to read the two-dimensional code C1 or the QR code C2, the imaging control unit 112 controls the imaging unit 151 to perform imaging processing. When the display control unit 113 is notified of judgment result information described later from the judgment result acquisition unit 2119, the display control unit 113 forms a result notification image notifying the judgment result based on the notified judgment result information and displays it on the display unit 104. When the reception unit 111 receives an operation to read the two-dimensional code C1 in the above-mentioned product history confirmation operation, the light source control unit 115 turns on the ultraviolet light source 107. On the other hand, the light source control unit 115 turns off the ultraviolet light source 107 when the reception unit 111 receives an operation for reading the QR code C2 in the above-mentioned product registration operation or product history confirmation operation.

[0044] When new judgment criterion information and product identification information are stored in the judgment information storage unit 131 after the reception unit 111 receives the above-mentioned product history confirmation operation, the judgment request unit 2116 generates judgment request information including the judgment criterion information and product identification information stored in the judgment information storage unit 131 and transmits it to the cloud server 2002. When the reception unit 111 receives the above-mentioned product history confirmation operation, the judgment result acquisition unit 2119 generates judgment criterion request information including the product identification information stored in the judgment information storage unit 131 and transmits it to the cloud server 2, thereby acquiring judgment result notification information transmitted from the cloud server 2002. Then, the judgment result acquisition unit 2119 extracts judgment result information included in the acquired judgment result notification information and notifies the display control unit 113.

[0045] 9, the cloud server 2002 includes a CPU 201, a main memory unit 202, an auxiliary memory unit 203, a communication unit 206, and a bus 209 connecting the various units. The CPU 201 includes, for example, a multi-core processor for use as a server. The main memory unit 202 is a volatile memory and is used as a working area for the CPU 201, and the auxiliary memory unit 203 is a non-volatile memory and stores programs for realizing various functions of the cloud server 2002. The communication unit 206 includes an interface for connecting to a wide area network NW1.

[0046] The CPU 201 reads out the program stored in the auxiliary storage unit 203 into the main storage unit 202 and executes it, thereby functioning as a criterion information acquisition unit 2211, an authenticity determination request acquisition unit 2212, an authenticity determination unit 2213, and a determination result notification unit 2214, as shown in Fig. 10. The auxiliary storage unit 203 shown in Fig. 9 also has a criterion information storage unit 2231, as shown in Fig. 10. The criterion information storage unit 2231 stores the above-mentioned determination information and product identification information in association with each other.

[0047] When the criterion information acquisition unit 2211 acquires the above-mentioned criterion notification information transmitted from the printing machine 2004, it extracts the criterion information included in the acquired criterion notification information. Then, based on a combination of the criterion information and the product identification information indicated by the criterion information, the criterion information acquisition unit 2211 stores the criterion information and the product identification information in the criterion information storage unit 2231 in association with each other.

[0048] When the authenticity judgment request acquisition unit 2212 acquires the aforementioned judgment request information transmitted from the terminal device 2001, it extracts the judgment information and product identification information contained in the acquired judgment request information, and notifies the authenticity judgment unit 2213 of the extracted judgment information and product identification information.

[0049] The authenticity determination unit 2213 performs authenticity determination of the product PR based on the combination of the determination information and the product identification information stored in the determination criterion information storage unit 2231 and the combination of the determination information and the product identification information notified from the authenticity determination request acquisition unit 2212. Specifically, the authenticity determination unit 2213 determines whether or not the combination of the determination information and the product identification information notified from the authenticity determination request acquisition unit 2212 exists among the combinations of the determination information and the product identification information stored in the determination criterion information storage unit 2231, and if it exists, determines that the product PR is genuine, and if it does not exist, determines that it is a counterfeit. The authenticity determination unit 2213 notifies the determination result information indicating the determination result to the determination result notification unit 2214. The determination result notification unit 2214 generates determination result notification information including the notified determination result information and transmits it to the terminal device 2001.

[0050] Next, the operation of the authenticity determination system according to the present embodiment will be described with reference to FIG. 11. First, when the printing company performs a print start operation to start printing the above-mentioned two-dimensional code C1 and QR code C2 on the packaging container PA by the printing machine 2004, the printing machine 2004 starts printing the two-dimensional code C1 and the QR code C2 on the packaging container PA (step S2001). Next, when the printing company performs a print end operation to end printing by the printing machine 2004, the printing machine 2004 ends printing the two-dimensional code C1 and the QR code C2 on the packaging container PA (step S2002). Next, the printing machine 2004 generates determination criterion notification information including determination criterion information indicating a combination of determination information and product identification information corresponding to each of the two-dimensional code C1 and the QR code C2 printed on the packaging container PA (step S2003). Then, the generated determination criterion notification information is transmitted from the printing machine 2004 to the cloud server 2002 (step S2004). On the other hand, when the cloud server 2002 acquires the aforementioned judgment criterion notification information transmitted from the printing machine 2004, it extracts the judgment criterion information contained in the acquired judgment criterion notification information, and stores the combination of the judgment information and product identification information indicated by the extracted judgment criterion information in the judgment criterion information storage unit 321 (step S2005).

[0051] Thereafter, it is assumed that the retailer of the product PR or the customer who purchased the product performs the above-mentioned product history confirmation operation on the terminal device 2001. In this product history confirmation operation, as described in the first embodiment, an operation is performed to sequentially capture images of the two-dimensional code C1 and the QR code C2 of the packaging container PA in the unfolded state. In this case, the terminal device 2001 captures an image of the two-dimensional code C1 of the packaging container PA with the ultraviolet light source 107 turned on, and captures an image of the QR code C2 with the ultraviolet light source 107 turned off (step S2006). Here, the authenticity determination device 1B stores captured image information indicating the captured images obtained by capturing the two-dimensional code and the QR code in the image buffer 121.

[0052] Next, the terminal device 2001 extracts a two-dimensional code image and a QR code image from the captured image indicated by the captured image information stored in the image buffer 121, and analyzes the extracted two-dimensional code image and QR code image to identify the determination information and the product identification information corresponding to the two-dimensional code image and the QR code image. Then, the terminal device 2001 stores the identified determination information and the product identification information in the determination information storage unit 131 (step S2007). Next, the terminal device 2001 generates determination request information including the determination information and the product identification information stored in the determination information storage unit 131 (step S2008), and the generated determination request information is transmitted from the terminal device 2001 to the cloud server 2002 (step S2009).

[0053] On the other hand, when the cloud server 2002 acquires the judgment request information, it extracts the judgment information and the product identification information included in the acquired judgment request information (step S2010). After that, the cloud server 2002 performs the authenticity judgment of the product PR based on the combination of the judgment information and the product identification information stored in the judgment criterion information storage unit 2231 and the combination of the judgment information and the product identification information notified from the authenticity judgment request acquisition unit 2212 (step S2011). Next, the cloud server 2002 generates the judgment result notification information including the judgment result information indicating the judgment result (step S2012), and the generated judgment result notification information is transmitted from the cloud server 2002 to the terminal device 2001 (step S2013). On the other hand, when the terminal device 2001 acquires the judgment result notification information transmitted from the cloud server 2002, it extracts the judgment result information contained in the acquired judgment result notification information (step S2014), and forms a result notification image showing the result of the authenticity judgment based on the extracted judgment result information, and displays it on the display unit 104 (step S2015).

[0054] Next, the authenticity determination process executed by the cloud server 2002 according to the present embodiment will be described with reference to FIG. 12. This authenticity determination process is started when a program for executing the authenticity determination process is started in the cloud server 2002. First, the judgment criterion information acquisition unit 2211 judges whether or not the judgment criterion notification information transmitted from the printing machine 2004 has been acquired (step S2101). If the judgment criterion information acquisition unit 2211 judges that the judgment criterion notification information has not been acquired (step S2101: No), the process of step S2103 described later is executed. On the other hand, if the judgment criterion information acquisition unit 2211 judges that the judgment criterion notification information has been acquired (step S2101: Yes), the judgment criterion information acquisition unit 2211 extracts the judgment criterion information included in the acquired judgment criterion notification information. Then, the judgment criterion information acquisition unit 2211 stores the combination of the judgment information and the product identification information indicated by the judgment criterion information in the judgment criterion information storage unit 2231 in association with each other (step S2102).

[0055] Next, the authenticity determination request acquisition unit 2212 judges whether or not the above-mentioned judgment request information transmitted from the terminal device 2001 has been acquired (step S2103). If the authenticity determination request acquisition unit 2212 judges that the judgment request information has not been acquired (step S2103: No), the process of step S2101 is executed again. On the other hand, if the authenticity determination request acquisition unit 2212 judges that the judgment request information has been acquired (step S2103: Yes), it extracts the judgment information and the product identification information included in the acquired judgment request information (step S2104) and notifies the authenticity determination unit 2213 of the extracted judgment information and the product identification information. Next, the authenticity determination unit 2213 performs an authenticity determination of the product PR based on the combination of the determination information and the product identification information stored in the determination criteria information storage unit 2231 and the combination of the determination information and the product identification information notified by the authenticity determination request acquisition unit 2212 (step S2105), and notifies the determination result information indicating the determination result to the determination result notification unit 2214. After that, the determination result notification unit 2214 generates determination result notification information including the notified determination result information and transmits it to the terminal device 2001 (step S2106). Next, the process of step S2101 is executed again.

[0056] As described above, the authenticity determination system according to the present embodiment eliminates the need for the manufacturer to register a combination of the determination information indicated by the two-dimensional code C1 and the product identification information indicated by the QR code C2. This reduces the workload of the manufacturer in determining the authenticity of product PR.

[0057] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, not only the two-dimensional code but also the QR code may indicate information for use in determining the authenticity of a product PR. In this case, the two-dimensional code and the QR code may indicate numerical values, and the numerical values ​​may be set to form a random number sequence.

[0058] In the embodiment, a sheet on which the above-mentioned two-dimensional code C1 and QR code C2 are printed so that they at least partially overlap each other may be attached to the outer wall of the packaging container. Here, for example, as shown in FIG. 13, the sheet SHE1 may be printed so that the two-dimensional code C1 and the QR code C2 are printed so that they partially overlap each other. The two-dimensional code C1 is a first code printed using ink containing a substance that absorbs light in the ultraviolet wavelength band and emits light in the visible wavelength band, and the QR code C2 is a second code printed using ink containing a substance that selectively absorbs or emits light in the visible wavelength band. Here, the two-dimensional code C1 and the QR code C2 may have different coding systems, that is, the information indicated by the two-dimensional code C1 and the information indicated by the QR code C2 may be different.

[0059] According to this configuration, the authenticity of the product PR contained in the packaging container can be verified using the information indicated by the two-dimensional code C1 and the QR code C2. In addition, since the wavelength bands of the light irradiated to the two-dimensional code C1 and the QR code C2 when reading them are different, misreading of the two-dimensional code C1 or the QR code C2 can be prevented.

[0060] In the second embodiment, the cloud server 2002 may include a logistics history storage unit that stores logistics history information of a product PR, similarly to the first embodiment. Then, when the cloud server 2002 acquires logistics history notification information transmitted from terminal devices possessed by not only manufacturers and retailers but also intermediate traders such as wholesalers, the cloud server 2002 may extract product identification information and logistics history information contained in the acquired logistics history notification information, and store the extracted product identification information and logistics history information in the logistics history storage unit in association with each other.

[0061] In addition, the various functions of the authenticity determination device 1 according to the present disclosure may be realized by software, firmware, or a combination of software and firmware. In this case, the software or firmware may be written as a program, and the program may be stored and distributed in a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disc Read Only Memory), a DVD (Digital Versatile Disc), or an MO (Magneto-Optical Disc), and the program may be read and installed in a computer to configure a computer capable of realizing each of the above-mentioned functions. In addition, when each function is realized by sharing the work between an OS (Operating System) and an application, or by cooperation between the OS and an application, only the parts other than the OS may be stored in the recording medium.

[0062] Furthermore, each program can be superimposed on a carrier wave and distributed via a network. For example, the program can be posted on a bulletin board (BBS, Bulletin Board System) on the network and distributed via the network. These programs can then be started and run under the control of the OS in the same way as other application programs, thereby enabling the above-mentioned processing to be performed.
