In the figure, the product database 10 includes “product ID”, “manufacturer name”, “product code”, “watermark image”, “watermark information”, “release date”, “production end date”, “recall presence / absence”, and the like. It consists of each item. Returning to FIG. 2, the digital watermark embedding unit 101 embeds predetermined watermark information in a product image registered in the product database 10 by a predetermined method to generate a watermark image. Then, the generated watermark image is overwritten on the original image in the product database 10, and the watermark information is registered (path (c)).

  Since the technique for embedding watermark information in an image is known, the description thereof is omitted here. The digital watermark embedding unit 101 uses a manufacturer name, a JAN (Japan Article Number) code, a product code, a serial number, and the like as watermark information. Note that the watermark information is not limited to the manufacturer name, JAN code, product code, serial number, etc., as long as the location of the watermark image to be generated is known and the product can be specified. A thing may be used. The watermark image transmission unit 102 transmits the watermark image generated by the digital watermark embedding unit 101 to the maker terminal device 2 (route (d) (e)).

  The recall product registration unit 103 changes the presence / absence of recall of the corresponding product from the default “No” to “Yes” in the product database 10 by receiving the recall occurrence notification transmitted from the manufacturer terminal device 2 ( (F) → (G) route).

  The detection target product image acquisition unit 104 acquires a watermark image or the like of the product that is the detection target from the commerce exhibition server 3-1 (the route (H)). For example, the commerce exhibition server 3-1 has a product image (including a watermark image) registered in the commerce exhibition database 30-1 and its detailed information (user information of an auction exhibitor or shopping exhibitor) every predetermined period. , The purchaser history information of the purchaser who purchased the product) is transmitted to the recalled product detection support server 1. Further, for example, every time information is newly registered in the commerce exhibition database 30-1, the commerce exhibition server 3-1 newly registers the product image (including a watermark image) and its detailed information (auction listing). User information of the exhibitor or shopping exhibitor, purchaser history information of the purchaser who purchased the product, etc.) is transmitted to the recalled product detection support server 1. When the product image is sent from the commerce exhibition server 3-1, the detection target product image acquisition unit 104 determines whether the product image is a watermark image, and does not acquire images other than the watermark image. May be.

  The recall product detection unit 105 reads the watermark information of the recall target product from the product database 10 when a recall occurrence notification is transmitted from the manufacturer terminal device 2 ((re) route). Then, watermark information is extracted from the image acquired by the detection target product image acquisition unit 104 by a predetermined method, and the extracted watermark information is compared with the read watermark information to determine a match. If they match, the watermark image (image from which watermark information has been extracted) acquired by the detection target product image acquisition unit 104 and its detailed information, and the manufacturer name and product code related to the recall target product registered in the product database 10 Are output to the notification unit 106. In particular, when the product being exhibited has not been purchased or has not been awarded, the watermark image of the recalled product and the user information of the auction exhibitor or shopping exhibitor are output, and the product being exhibited When purchased or sold, the watermark image and purchaser history information of the recall target product are output. The notification unit 106 transmits the watermark image of the recall target product detected by the recall product detection unit 105 and its detailed information to the maker terminal device 2 (route (N)). Note that a method for extracting watermark information from an image is already known, and a description thereof will be omitted here.

FIG. 4 is a diagram showing a sequence at the time of image registration by the recall product detection support server 1. In the figure, the maker terminal device 2 accesses the recall product detection support server 1 and, after two-way communication is established, transmits a product image and its detailed information (product ID, manufacturer name, product code, etc.). When the recall product detection support server 1 receives the product image and the detailed information transmitted from the manufacturer terminal device 2, the recall product detection support server 1 registers them in the product database 10. After recalling the product image and its detailed information, the recall product detection support server 1 generates a watermark image by embedding predetermined watermark information in the registered product image, and overwrites the original product image with the watermark image. , Register watermark information. Next, the recall product detection support server 1 reads the watermark image registered in the product database 10 and transmits it to the manufacturer terminal device 2.

  FIG. 5 is a diagram showing a sequence when the recall product detection support server 1 detects the recall product. In the figure, the commerce exhibition server 3-1 periodically receives, for example, a watermark image and detailed information thereof (user information of an auction exhibitor or shopping exhibitor, purchaser history information of a purchaser who has purchased a product, etc.). The data is transmitted to the recall product detection support server 1 (the transmission timing is indicated by a dotted arrow). When a recall occurs, the manufacturer terminal device 2 notifies the recall product detection support server 1 of the occurrence of the recall. When the recall product detection support server 1 receives a recall notification from the manufacturer terminal device 2, the recall product detection support server 1 registers the recall target product in the product database 10. That is, in the product database 10, for example, based on the product code included in the recall occurrence notification, the recall presence / absence of the corresponding product is changed from the default “none” to “present”.

  The recall product detection support server 1 reads the watermark information of the recall target product from the product database 10, extracts the watermark information from all the images currently acquired from the commerce exhibition server 3-1, and reads the extracted watermark information. The watermark information is compared to determine whether they match. If they match, the corresponding watermark image and its detailed information (user information of the auction exhibitor or shopping exhibitor, purchaser history information of the purchaser who has purchased the product, etc.), and those registered in the product database 10 The manufacturer name, product code, etc. regarding the recall target product are transmitted to the manufacturer terminal device 2. Note that if the watermark information cannot be extracted from the image acquired from the commerce exhibition server 3-1, the comparison process is not performed, and it is determined that they do not match.

  FIG. 6 is a flowchart for explaining image registration / recall product detection processing by the recall product detection support server 1. In the figure, first, the recall product registration unit 103 determines whether there is a recall occurrence notification from the manufacturer terminal device 2 (step S1). If it is determined in this determination that there is no recall occurrence notification (step S1: NO), the product image / detail registration unit 100 displays the product image from the manufacturer terminal device 2 and its detailed information (product ID, manufacturer name, product code). Etc.) is determined (step S2). In this determination, when it is determined that there is no product image and its detailed information (step S2: NO), the detection target product image acquisition unit 104 determines whether there is information from the commerce exhibition server 3-1 ( Step S3).

  When the detection target product image acquisition unit 104 determines in step S3 that there is information from the commerce exhibition server 3-1, (step S3: YES), the image transmitted from the commerce exhibition server 3-1 and its image Detailed information (user information of an auction exhibitor or shopping exhibitor, purchaser history information of a purchaser who purchased a product, etc.) is acquired and stored (step S4). After this process is performed, the process returns to step S1. When the detection target product image acquisition unit 104 determines that there is no information from the commerce exhibition server 3-1 in the determination in step S <b> 3 (step S <b> 3: NO), the process returns to step S <b> 1 as it is.

  If the product image / detail registration unit 100 determines in step S2 that there is product image / detailed information (step S2: YES), the product image / detailed information is registered in the product database 10 (step S2). S5). Next, the digital watermark embedding unit 101 embeds predetermined watermark information into a product image registered in the product database 10 by a predetermined method to generate a watermark image (step S6). Then, the generated watermark image and watermark information are registered in the product database 10 (step S7). In this case, the watermark image is overwritten on the original product image. When the watermark image and watermark information are registered in the product database 10 by the digital watermark embedding unit 101, the watermark image transmitting unit 102 reads the watermark image from the product database 10 and transmits it to the manufacturer terminal device 2 (step S8). . After this process is performed, the process returns to step S1.

  If the recall product registration unit 103 determines in step S1 that there is a recall occurrence notification (step S1: YES), the recall product registration unit 103 registers the recall target product in the product database 10 (step S9). That is, among the products registered in the product database 10, the presence / absence of recall of the product corresponding to the recall is changed from the default “none” to “present”. Next, the recall product detection unit 105 reads the watermark information of the recall target product registered in the product database 10 (step S10). Next, the recall product detection unit 105 extracts watermark information from all images sent from the commerce exhibition server 3-1, and compares the extracted watermark information with the watermark information of the recall target product read from the database 10. (Step S11). The recall product detection unit 105 determines whether the product corresponds to the recall target product from the comparison result (step S12). If it is determined that they match in this determination, that is, if it is determined that the product corresponds to the recall target product (step S12: YES), the image corresponding to the recall target product (image in which the matching watermark information is embedded) and its detailed information (auction) The user information of the exhibitor or the exhibitor of shopping, the purchaser history information of the purchaser who purchased the product, etc.) are stored (step S13).

  Next, the recall product detection unit 105 determines whether or not the watermark information of the recall target product is the last one (step S14), and determines that the watermark information of the recall target product is not the last one (step S14). Step S14: NO), the process returns to Step S11, and comparison processing is performed on the next watermark information among the watermark information of the recall target product read from the product database 10. On the other hand, if it is determined in step S12 that the product does not correspond to the recall target product (step S12: NO), the process of step S13 is not performed and the determination of step S14 is performed as it is.

  When the recall product detection unit 105 determines that the watermark information is the last one in the determination in step S14 (step S14: YES), the image related to the detected recall target product and its detailed information (auction exhibitor or shopping) Exhibitor's user information, purchaser history information of the purchaser who purchased the product), and the manufacturer name and product code related to the recall target product registered in the product database 10 are transmitted to the manufacturer terminal device 2 ( Step S15). After this process is performed, the process returns to step S1.

  As described above, the recall product detection support server 1 according to the first embodiment receives the product image and the detailed information (product ID, manufacturer name, product code, etc.) transmitted from the manufacturer terminal device 2 and receives the product database 10. And a watermark image in which watermark information is embedded in the registered image is generated, the watermark image and the watermark information are registered, and the watermark image is transmitted to the maker terminal device 2, and then transmitted from the maker terminal device 2. When the recall notification has been received, the watermark information of the recall target product registered in the product database 10 is compared with the watermark information extracted from the product image registered in the commerce exhibition database, and the watermarks of all matching products are compared. Image and its detailed information (user information of auction exhibitors or exhibitors of shopping, purchases that purchased products) The purchaser history information, etc.) were to be sent to the manufacturer terminal device 2. Thereby, since the product is managed by the watermark image in which the watermark information is embedded in the product image, input mistakes are reduced and the management information is not easily falsified as compared with the case of managing using the product code or the like. Therefore, the detection failure of the recall target product is reduced, the collection rate of the product by the recall can be improved, and the reliability of the manufacturer for the recall can be improved.

  The recall product detection support server 1 according to the first embodiment transmits each of the specific commerce exhibition servers 3-1, 3-2,...
