Description

The present invention relates to an authenticity determination method, an authenticity determination system, and an authenticity determination apparatus.

In the case of branded bags, luxury watches, etc., the seller (brand owner) sells the goods (goods) and certificates together to the purchaser (end user). At that time, a certain degree of anti-counterfeiting technology is often adopted for both products and certificates, but there is room for counterfeit products to enter in returned goods and secondary distribution.
Anti-counterfeiting techniques include managing articles by manufacturing serial numbers, mounting IC tags, and the like. On the other hand, there are also countermeasures for certificates, such as pattern printing, micro-characters, and holograms to prevent copying. However, neither is perfect.
When an external organization determines the authenticity of an article, an appraiser conducts the appraisal, and the organization or company to which the appraiser belongs issues a certificate certifying the authenticity. In the work of authenticity determination of articles by appraisers, there is a problem that the determination result depends on the person because the competence and experience of the appraiser is a variable factor. Therefore, at present, the burden of double-checking by multiple appraisers is heavy. In addition, since neither an appraiser nor an end user can judge the authenticity of the certificate itself, there is a problem that the existence of the certificate itself becomes a mere mere existence.

FIG. 1 is a block diagram showing a schematic configuration of an authenticity determination system 1 according to this embodiment.
In the example shown in the figure, the authenticity determination system 1 includes a certificate data generation device 10, a certificate imaging device 11, a certificate electronic data issuing system 12, an article data generation device 20, and an authentic product imaging device 21. , a data holding system 30 , a client terminal 40 , an object imaging device 41 , and an authenticity determination device 50 . The certificate data generation device 10, the certificate electronic data issuing system 12, or the article data generation device 20, and the data holding system 30 are interconnected for communication via a network such as the Internet. Further, the certificate electronic data issuing system 12, the data holding system 30, or the client terminal 40, and the authenticity determination device 50 are connected for mutual communication via a network such as the Internet.

The certificate imaging device 11 images a printed certificate of an article sold by an article seller (for example, a brand owner). A printed certificate is a certificate printed on a printed material such as paper or plastic film. The certificate imaging device 11 transmits captured image data of the captured certificate (hereinafter referred to as “authentic certificate captured image”) to the certificate data generation device 10 . Certificates printed on printed matter include printed matter with normal printing, holograms, IC tags, security printing (for example, intaglio printing, printing with fluorescent/phosphorescent ink, micro-characters, colorful printing, etc.), etc. The unique information of the certificate is concealed (embedded) in advance by an anti-counterfeiting medium (technology related to anti-counterfeiting function). Printed matter that has undergone normal printing includes the unique information of the certificate by using artifact metrics, which will be described later. Therefore, the unique information of the certificate is information that is not explicitly known to the end user. The unique information of the certificate is a numeric or alphabetic password or code (for example, QR (Quick Response) code (registered trademark)). The code may indicate a password.

The certificate data generation device 10 receives the captured image of the authentic certificate from the certificate imaging device 11, and generates unique information of the certificate by image-analyzing the received captured image of the authentic certificate. The unique information of a certificate is the password or code hidden in the certificate, the information on the anti-counterfeit function attached to the certificate, or the printing fluctuations that occur during the production of the certificate (for example, slight differences in bleeding and color). etc.) or artifact metrics information that depends on the state of the paper surface is embedded in the data of the body of the certificate. The artifact metrics information is information based on artifact metrics (printed fingerprints, object fingerprints) that indicate fluctuations in printing and the processing state of the paper surface itself. The data of the main body of the certificate is, for example, data displayed as visible information on the display screen of the display device when the certificate is displayed on the display screen. The data of the main body of the certificate are, for example, the product name of the article, the name of the store where the article was sold, the date of sale, the production number, and the like. The certificate data generation device 10 adds identification information (for example, a serial number) of the article (product) to be certified to the authenticity certificate captured image. Save to storage. Further, the certificate data generation device 10 transmits to the data holding system 30 the captured image of the genuine certificate to which the identification information of the article is added and the unique information of the certificate.

The certificate electronic data issuing system 12 is composed of one or a plurality of server devices, and issues electronic data of certificates of goods sold by the goods seller to the goods seller on demand. The electronic data of the issued certificate is given the identification information of the article to be certified. Further, unique information of the certificate is added to the electronic data of the issued certificate. The certificate electronic data issuing system 12 uses, for example, electronic watermarking technology to hide unique information (eg, password or code) within the electronic data of the certificate in a form that makes it difficult for the end user (eg, purchaser) to recognize it. Further, the certificate electronic data issuing system 12 generates, as unique information of the certificate, information relating to a forgery prevention function such as an electronic watermark attached to the certificate. The certificate electronic data issuing system 12 stores the electronic data of the issued certificate (including the image image of the certificate) and the unique information of the certificate in a predetermined storage area within the certificate electronic data issuing system 12, Send to data retention system 30 .
Hereinafter, the captured image of the genuine certificate and the electronic data of the certificate issued by the certificate electronic data issuing system 12 will be collectively referred to as "authentic certificate data". In other words, the authentic certificate data may be either the authentic certificate captured image or the electronic data of the certificate issued by the certificate electronic data issuing system 12 .

The genuine article imaging device 21 images articles sold by article sellers. The genuine product imaging device 21 transmits captured image data of the captured product (hereinafter referred to as “genuine product captured image”) to the product data generation device 20 .

The product data generation device 20 receives the captured genuine product image from the genuine product image capturing device 21 and generates unique information of the product by performing image analysis on the received genuine product captured image. The product data generation device 20 adds the identification information of the product to the captured image of the genuine product, and stores it in a predetermined storage area in the product data generation device 20 together with the unique information of the product. In addition, the article data generation device 20 transmits the captured image of the genuine article to which the identification information of the article is added and the unique information of the article to the data holding system 30 .

The data holding system 30 is composed of one or more server devices, and includes the authentic certificate data and certificate unique information received from the certificate data generation device 10 or the certificate electronic data issuing system 12, and the article data generation device 20. The captured image of the genuine article received from and the unique information of the article are associated with each other based on the identification information of the article and stored.

The target item imaging device 41 captures an image of an item for which authenticity determination is requested (hereinafter referred to as "target item") and its certificate (hereinafter referred to as "target certificate"). The target item imaging device 41 captures captured image data of the target item (hereinafter referred to as “target product captured image”) and captured image data of the target certificate (hereinafter referred to as “target certificate captured image”). ) is sent to the client terminal 40 . Note that the target article imaging device 41 may be a camera built into the client terminal 40 .

The client terminal 40 is a terminal device such as a smartphone, a tablet terminal, or a personal computer possessed by a client (for example, a consumer or an end user) who requests authentication of an article. The client terminal 40 receives the target product image or the target certificate image from the target product imaging device 41, and gives the received image the date and time of image capturing and the position information at the time of image capturing. For example, the client terminal 40 sets the file creation date and time in the file information of the captured image as the image capturing date and time. Also, the client terminal 40 acquires position information at the time of imaging, for example, by GPS (Global Positioning System). For example, the client terminal 40 attaches the imaging date and time and positional information at the time of imaging as metadata to the captured image using EXIF (Exchangeable Image File Format). Then, the client terminal 40 transmits to the authenticity determination device 50 an authenticity determination request including the captured image of the target item to which the date and time of imaging and the position information at the time of capturing, the captured image of the target certificate, and the unique information of the client terminal 40 are included. do. The authentication request is data for requesting authentication of the imaged article and its certificate. The unique information of the client terminal 40 is identification information that can individually identify the client terminal 40, such as a serial number. Note that the client terminal 40 may include in the authenticity determination request information specifying the product, such as the brand name, product name, and category of the target product.

The authentication device 50 is composed of one or a plurality of server devices, and executes authentication of the target product and the target certificate based on the authentication request received from the client terminal 40 .

FIG. 2 is a block diagram showing a schematic configuration of the authentication device 50 according to this embodiment.
The authenticity determination device 50 includes a target product information acquisition unit 501 , a genuine product information acquisition unit 502 , a determination unit 503 and an output unit 504 .

The target item information acquisition unit 501 acquires by receiving from the client terminal 40 an authenticity determination request including the captured image of the target item, the captured image of the target certificate, and the unique information of the client terminal 40 .
The genuine product information acquisition unit 502 identifies the product to be subjected to authenticity determination based on the authentication request acquired by the target product information acquisition unit 501, and instructs the data storage system 30 to issue genuine product information for the specified product. Send. For example, the genuine product information acquisition unit 502 identifies the brand name, product name, and the like by image-analyzing the target product captured image or the target certificate captured image included in the request for authenticity determination. The genuine product information acquisition unit 502 acquires the genuine product information of the specified product by receiving it from the data holding system 30 . The genuine product information includes the genuine product captured image of the specified product, unique information of the product, authenticity certificate data, and unique information of the certificate.

The determination unit 503 determines the authenticity of the target product and the target certificate based on the authentication request acquired by the target product information acquisition unit 501 and the genuine product information acquired by the genuine product information acquisition unit 502 . Specifically, the determination unit 503 determines the authenticity of an article based on the target article imaging data and the genuine article imaging data, and the authenticity determination of the certificate based on the target certificate data and the authenticity certificate data. Based on the unique information of the client terminal 40 , the determination unit 503 determines whether or not the same client terminal 40 is the source of the captured image of the target article and the captured image of the target certificate. If the transmission sources are not the same, the determination unit 503 sets the authentication determination result to undeterminable, which indicates that the authentication cannot be determined. On the other hand, when the transmission source is the same client terminal 40, the determination unit 503 determines the authenticity based on the difference in the date and time when the image of the target product and the image of the target certificate are captured and the difference in the position information at the time of capturing. judge. For example, the determination unit 503 determines that the authenticity determination result cannot be determined when the difference in imaging date and time exceeds a predetermined time, and determines that the image of the target product and the target certificate are captured when the difference in imaging date and time is within a predetermined time. Authenticity determination may be performed based on images, captured images of genuine products, authenticity certificate data, product specific information, and certificate specific information.
Further, for example, the determination unit 503 may output a different degree of authenticity depending on whether the difference in imaging date and time exceeds a predetermined period of time. More specifically, when the difference in imaging date and time exceeds a predetermined time, the determining unit 503 outputs an authenticity determination result indicating that the degree of authenticity is low, and when the difference in imaging date and time is within the predetermined time, An authenticity determination result indicating that the degree of authenticity is high may be output.
Further, the determination unit 503 determines that the authenticity determination result cannot be determined when the difference in the position information (positional distance) at the time of imaging exceeds a predetermined range, and when the difference in the position information at the time of imaging is within the predetermined range. only, the authenticity determination may be performed based on the captured image of the target product, the captured image of the target certificate, the captured image of the genuine product, the authenticity certificate data, the unique information of the product, and the unique information of the certificate.
Further, for example, the determination unit 503 may output different degrees of authenticity depending on whether the difference in position information (distance between positions) at the time of imaging exceeds a predetermined reference distance. More specifically, when the difference in the position information at the time of imaging exceeds a predetermined reference distance, the determining unit 503 outputs an authenticity determination result indicating that the degree of authenticity is low, and the difference in the position information at the time of imaging exceeds the predetermined reference distance. If the distance is within the reference distance, an authenticity determination result indicating that the degree of authenticity is high may be output.

The determination unit 503 uses training data stored in advance based on the captured image of the target product, the captured image of the target certificate, the captured image of the genuine product, the authentic certificate data, the unique information of the product, and the unique information of the certificate. An artificial intelligence (AI) is used to determine the authenticity of the target product and the target certificate. For example, the judging unit 503 outputs a result of authenticity judgment (genuine or counterfeit, degree of authenticity (degree of authenticity), difference from genuine product, etc.) by artificial intelligence such as machine learning or a neutral network. Authenticity determination is performed by inputting into the model a captured image of the target product, a captured image of the target certificate, a captured image of the genuine product, authenticity certificate data, unique information of the product, or unique information of the certificate.

The determining unit 503 performs authenticity determination using the captured image of the target product and the captured image of the genuine product. Authenticity determination of the article is performed based on the unique information. For example, the determining unit 503 determines that the product is genuine (increases the degree of authenticity) when the product-specific information can be extracted from the captured image of the target product, and determines that the product is genuine when the product-specific information cannot be extracted. is judged to be a fake (reduce the degree of authenticity).

In addition, when the determining unit 503 determines the authenticity of the target certificate using the captured image of the target certificate and the authenticity certificate data, and as a result determines that the target certificate is genuine (for example, the degree of authenticity is equal to or higher than a predetermined value). Then, the authenticity determination of the certificate is performed based on the unique information of the certificate. For example, in the case where a password is assigned to the certificate in advance by a technology related to the forgery prevention function, the determination unit 503 determines that the certificate is genuine if the assigned password can be extracted from the captured image of the target certificate. (higher authenticity), and if the password could not be extracted, it is determined that the certificate is fake (lower authenticity). Further, when the unique information of the certificate is the artifact metrics information, the determining unit 503 extracts the artifact metrics information from the captured image of the target certificate. The determination unit 503 determines that the certificate is genuine (authenticity) as the degree of matching between the extracted artifact metrics information and the artifact metrics information indicated by the unique information of the certificate is higher (for example, a predetermined value or more). higher), and the lower the degree of matching of the artifact metrics information (for example, less than a predetermined value), the certificate is determined to be fake (lower the degree of authenticity). Further, when the unique information of the certificate is information related to an anti-counterfeiting function, the determination unit 503 determines that the certificate is genuine when the corresponding anti-counterfeiting function can be extracted from the captured image of the target certificate. (the degree of authenticity is increased), and if the forgery prevention function cannot extract the captured image of the target certificate, the certificate is determined to be a forgery (the degree of authenticity is decreased).

The output unit 504 notifies the requester of the authenticity determination result by the determination unit 503 by transmitting it to the client terminal 40 . In addition, the output unit 504 may notify the authenticity determination person or the product seller by transmitting the authentication result to the terminal device of the person performing the authentication determination or the terminal device of the product seller, if necessary.

Next, the operation of the authenticity determination system 1 will be described.

If the difference in imaging date and time exceeds the predetermined time (step S504: No), the process proceeds to step S503, the output unit 504 notifies the client terminal 40 that determination is not possible, and the process ends.

On the other hand, if the difference between the photographing dates and times is within the predetermined time (step S504: Yes), the determination unit 503 determines the difference between the position information at the time when the captured image of the target product was captured and the position information at the time when the captured image of the target certificate was captured. is within a predetermined range (step S505). If the difference in position information at the time of imaging exceeds the predetermined range (step S505: No), the process proceeds to step S503, the output unit 504 notifies the client terminal 40 that determination is not possible, and the process ends.

On the other hand, if the difference in position information at the time of imaging is within the predetermined range (step S505: Yes), the genuine product information acquisition unit 502 acquires genuine product information from the data holding system 30 (step S506).

Next, the determination unit 503 determines whether the target product is genuine or counterfeit using the captured image of the target product and the captured image of the genuine product (step S507). If it is determined to be a counterfeit based on the captured image of the target product and the captured image of the genuine product (Step S507: Counterfeit), the determination unit 503 determines that the target product is a counterfeit (Step S508).

On the other hand, if the determination unit 503 determines that the target product is genuine based on the captured image of the target product and the captured image of the genuine product (step S507: genuine), the target product is genuine or counterfeit based on the unique information of the product. (step S509). If it is determined that the product is a fake based on the unique information of the product (step S509: fake), the process proceeds to step S508, and the determination unit 503 determines that the target product is a fake. On the other hand, if the determining unit 503 determines that the item is genuine based on the unique information of the item (step S509: genuine), it determines that the target item is genuine (step S510).

Subsequently, the determination unit 503 determines whether the target certificate is genuine or counterfeit using the target certificate captured image and the authentic certificate captured image (step S511). If it is determined to be a forgery based on the captured image of the target certificate and the captured image of the authentic certificate (step S511: fake), the determination unit 503 determines that the target certificate is a forgery (step S512).

On the other hand, if the determining unit 503 determines that the target certificate is genuine based on the captured image of the target certificate and the captured image of the authentic certificate (step S511: genuine), the target certificate is genuine based on the unique information of the certificate. or a counterfeit (step S513). If it is determined that the certificate is fake based on the unique information of the certificate (step S513: fake), the process proceeds to step S512, and the determination unit 503 determines that the target certificate is fake. On the other hand, if the determination unit 503 determines that the certificate is genuine based on the unique information of the certificate (step S513: genuine), it determines that the target certificate is genuine (step S514).

Then, the output unit 504 notifies the client terminal 40 of the authenticity determination result by the determination unit 503 (step S515). In addition, the output unit 504 notifies the terminal device of the authenticity determination executor and the terminal device of the product seller of the result of the authentication determination. After that, the process ends.

In the authenticity determination process shown in the figure, the authenticity determination device 50 determines whether the target product or the target certificate is genuine or counterfeit. The degree (for example, percentage, level, etc.), the difference from the genuine product, or the like may be determined.
In addition, the authenticity determination device 50 does not determine the authenticity determination result when the difference in the imaging date/time or the positional information at the time of imaging between the image of the target product and the image of the target certificate is greater than or equal to a predetermined value. Alternatively, the difference may be reflected in the authenticity determination, such as by lowering the degree of authenticity.
Further, in the authenticity determination process shown in the figure, at least one of the steps S502, S504, and S505 does not necessarily have to be executed, but may be added as appropriate according to the accuracy required for the authenticity determination. may

As described above, according to the present embodiment, the authenticity determination system 1 includes the data storage system 30 that associates and stores an authentic product captured image obtained by capturing an authentic product and authenticity certificate data related to the certificate of the product. a target product information acquisition unit 501 for acquiring a target product image obtained by imaging an object to be authenticated and a target certificate image obtained by imaging a certificate of the target product; and a target product image. and an authenticity determination device 50 including a determining unit 503 that determines the authenticity of an article based on the captured image of the genuine product, and determines the authenticity of the certificate based on the captured image of the target certificate and the authenticity certificate data.

With the above-described configuration, it is possible to automatically determine the authenticity of an article and a certificate by image recognition of each captured image. can. In addition, authenticity can be determined with a certain degree of accuracy regardless of the skill or experience of the appraiser. In addition, since both the article and the certificate are authenticated, a more accurate determination result can be obtained than when either one is determined. Therefore, it is possible to suppress fraudulent acts such as substituting an article with only a genuine certificate or forging a certificate, thereby suppressing the circulation of fraudulent articles.

Further, the data holding system 30 stores the unique information of the sold article or the unique information of the certificate of the article in association with the captured image of the genuine article and the authenticity certificate data, and the determination unit 503 stores the unique information of the article. Alternatively, authenticity is determined using at least one of the unique information of the certificate. As a result, authenticity can be determined with higher accuracy than when only the captured image is used.

Also, the unique information of the certificate includes at least one of information about the anti-counterfeiting function of the certificate or information about the artifact metrics. For example, anti-counterfeiting media such as IC tags, holograms, intaglio printing, fluorescent/phosphorescent ink printing, micro-characters, or colored printing attached to printed certificates, and electronic watermarks attached to electronic data certificates. By utilizing , the authenticity of the certificate can be guaranteed more reliably. In addition, when printing certificate information on a printed matter, it is not possible to produce exactly the same information due to various factors at the time of printing, and printing fluctuations (bleeding and slight differences in color tone) occur. By using such printing fluctuations and the processing state of the printed material (for example, paper surface) itself, authenticity can be determined with higher accuracy.

Also, the unique information of the certificate is a password or code previously hidden in the certificate by the forgery prevention function. As a result, unique information that is not explicitly disclosed to the end user, who requests authentication, can be used to determine the authenticity of a certificate, so that counterfeiting such as duplication can be detected with high accuracy, and authenticity is more reliably guaranteed. can do.

Further, the determination unit 503 determines authenticity by artificial intelligence using pre-stored teacher data. As a result, it is possible to show a more accurate authenticity determination result.

Further, the genuine certificate data is a photographed image of the printed matter when the certificate is a printed matter, and is electronic data of the certificate when the certificate is electronic data. As a result, even if the certificate is printed on a printed matter, the captured image can be used to automatically determine the authenticity of the certificate. can.

Further, the determination unit 503 determines authenticity only when the captured image of the target product and the captured image of the target certificate are acquired from the same terminal. Authenticity determination is performed only when the captured image of the target item and the captured image of the target certificate are sent from the same terminal, that is, when there is a high possibility that the item and the certificate are in the same place (by the same owner). By doing so, it is possible to exclude articles and certificates in different places (having different holders) from being subject to authenticity determination.

Further, the determination unit 503 determines authenticity based on the difference between the imaging date and time of the captured image of the target product and the imaging date and time of the captured image of the target certificate. By confirming that there is no large discrepancy between the imaging dates and times of the captured image of the target article and the captured image of the target certificate, it is possible to ensure that the article and the certificate exist in substantially the same time zone. Therefore, by confirming that the article and the certificate existed in the same time slot, the authenticity can be secured more reliably.

Further, the determination unit 503 determines authenticity based on the difference between the position information when the captured image of the target product is captured and the position information when the captured image of the target certificate is captured. By confirming that there is no significant discrepancy in the location information at the time of capturing the image of the subject item and the image of the subject certificate, it is possible to confirm that the item and the certificate exist in roughly the same place (under the same owner). can be guaranteed. Therefore, by confirming that the article and the certificate existed in the same place, the authenticity can be ensured more reliably.
