[0016] Overview A monitoring device according to an embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a monitoring system 1 according to this embodiment is a system that monitors the status of products offered by a predetermined product provider on a shopping mall site.

[0017] Here, a shopping mall site is an e-commerce site that sells products and services over the Internet, and is a website where products are offered by one or more sellers other than the site operator. The mall-type shopping site assumed in this embodiment has a web page (hereinafter referred to as a "product sales page") for introducing and selling each product it handles. On the product sales page, information on all sellers who are selling the listed products, as well as information such as the prices of the products sold by each seller, can be seen at a glance.

[0018] Furthermore, the product sales page provides a cart for each seller. The cart is associated with information that identifies the seller, and when a prospective buyer specifies a cart for each seller, the product listed by the specified seller is added to the cart. The "cart" referred to here is an electronic object for adding products to a shopping list. When a person who wishes to purchase a product adds the product to the shopping list by specifying it in the cart, they then purchase the product by separately requesting payment processing.

[0019] A monitor who operates the monitoring system 1 provides users with a product monitoring service that uses the monitoring system 1. In providing the monitoring service, a website (hereinafter referred to as the "service site") is provided for the convenience of users, and users can check various information on the service site and provide information necessary to receive the monitoring service.

[0020] ●Function configuration As shown in Figure 2, the monitoring system 1 is configured to be able to communicate with a mall management server 2 that provides a mall-type shopping site, a user terminal 3 that is a provider of specified products and is used by users of the system, via a network NW such as the Internet. Furthermore, sellers who sell products on the shopping mall site can use seller terminals 4 to access mall management server 2 via network NW and sell products.

[0021] The monitoring system 1 may be realized by executing a predetermined computer program on a personal computer, tablet terminal, smartphone, etc., or some or all of its functions may be realized by a cloud computer. The monitoring system 1 may also be composed of multiple hardware components.

[0022] This monitoring system 1 is configured with functional units consisting of a user information storage unit 1A, a whitelist storage unit 1B, a shopping site information storage unit 1C, an extraction processing unit 11, a discrimination processing unit 12, a notification processing unit 13, and a communication processing unit 14, using hardware resources such as a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), and a hard disk drive, and software resources such as a computer program executed by the CPU.

[0023] The user information storage unit 1A is a storage unit that stores information about users of the monitoring service provided by the monitoring system 1. The term "user" here refers to a user of the monitoring service and also to a provider of products sold on the shopping mall, such as a product manufacturer. Products provided by users are sold on the shopping mall through sellers. However, users themselves may also be sellers of products.

[0024] The user information storage unit 1A stores basic information such as the user's name and attributes, as well as information about products offered by the user. The product information is sufficient as long as it can identify the product when referring to product listing information extracted from a shopping mall, and includes the product name, model number, and product identification information individually assigned by the shopping mall. For example, if the shopping mall is Amazon (registered trademark), the product identification information may be ASIN (Amazon Standard Identification Number). Other examples of identification information include JAN codes, ISBN codes, etc.

[0025] The whitelist storage unit 1B is a storage unit that stores a whitelist that lists sellers that a user recognizes as appropriate sellers of a predetermined product. An appropriate seller is one who receives goods from the product provider through legitimate channels such as wholesale, while an inappropriate seller is one who sells goods through channels not approved by the product provider, such as through resale or parallel import. Inappropriate sellers also include sellers who sell counterfeit goods.

[0026] For example, as shown in FIG. 3, the whitelist storage unit 1B stores, for each user, a list of products provided by the user and sellers who are permitted as appropriate sellers of the products. In this embodiment, sellers listed on the whitelist are, for example, wholesalers of products. If the seller is a wholesaler, the name, identification number, contact information of the wholesaler, etc. of the wholesaler are appropriately stored as information related to the seller. In this case, the product associated with the seller is a product that the product provider wholesaled to the wholesaler, and predetermined identification information assigned to the product may be associated with the product. In addition, the seller can also include anyone designated by the user as a target of the whitelist. The user can also include themselves in the whitelist. This whitelist may be edited and registered by the user on the service site.

[0027] The shopping site information storage unit 1C is a storage unit that stores information about mall-type shopping sites. The shopping site information storage unit 1C stores, for example, information that can identify a shopping mall, as well as addresses such as URLs for accessing the shopping mall.

[0028] The extraction processing unit 11 accesses a shopping mall site and executes an extraction process to extract listing information for a predetermined product on the site. The listing information extracted in this extraction process may include, for example, information related to the seller of the specified product, information related to the cart created for the specified product, information contained on the product sales page, information related to the time the product was listed and its sales status, etc. In the case of a shopping mall, multiple sellers may offer products with the same identification information. Each seller may set a different selling price and shipping fee for the same product. A buyer can purchase a product by specifying the seller from which to purchase. In such a situation, obtaining the listing information makes it easier for the user who provides the product to monitor the product and analyze its distribution.

[0029] Furthermore, the extraction processing unit 11 crawls the mall-type shopping site at a predetermined timing and scrapes the listing information of a predetermined product, but the timing is not particularly limited and may be a fixed timing or any timing set by the monitor or user.

[0030] In addition to the listing information, the extraction processing unit 11 can also acquire the sales history of the product. The sales history includes, for example, the identification information of the sold product, the number of purchases, the number of products, the selling price, shipping fees, the delivery company, the delivery method, the date and time of the sale, and information about the purchaser. The sales history may also include information about products purchased simultaneously on the shopping mall site.

[0031] The extraction processing unit 11 extracts listing information for a specific product by executing functions of an API (Application Programming Interface) provided by a shopping mall site or an API provided by a third party. The extraction processing unit 11 may extract information such as listing information from the mall management server 2 by executing functions of the API, or may acquire information from a purchase screen that the mall management server 2 displays on the purchaser's terminal. In this case, the extraction processing unit 11 includes, for example, a text information extraction unit that acquires the source code of the purchase screen, and an image extraction unit that extracts images included in the purchase screen or a search result screen that displays links to multiple product sales pages. The extraction processing unit 11 may acquire a portion indicating a display image from the source code, or may acquire image data indicated by the display image.

[0032] Furthermore, the extraction processing unit 11 may search for product images included in the product listing information on the shopping mall and extract products identical or similar to a predetermined product using appropriate image recognition technology. AI technology can be applied to image recognition. Product images refer to all images displayed as image data in the image display area of ​​the shopping mall, and may be, for example, photos of product packaging or the product itself, or text only such as the product name, logo, or catchphrase, or a combination of these. This configuration can also extract listing information for identical products with different product identification information, or for counterfeit products.

[0033] Counterfeit product images are likely to use photos, packaging photos, product names, logos, or catchphrases of products similar to the searched product. Counterfeit sellers may also use edited images of genuine products. Since potential buyers often make purchases based on product images, counterfeit products with similar product images are particularly malicious because they hinder the purchase of genuine products. Therefore, this configuration contributes to safe and fair transactions of genuine products.

[0034] The extraction processing unit 11 may extract product images that include predetermined information such as a package photo, a photo of the product itself, the product name, logo, or catchphrase. In this case, the extraction processing unit 11 may also extract images in which the display magnification of the predetermined information has been changed. This configuration allows for accurate extraction even when a seller who resells or lists counterfeit products uses edited genuine product images.

[0035] The extraction processing unit 11 may extract product images by applying OCR technology to read characters contained in the product images. This configuration allows for accurate extraction even when only the text content, such as the product name, matches in the image.

[0036] The extraction processing unit 11 may perform a product search on a shopping mall site and then perform the above-described image search on product images displayed on the search result screen. The extraction processing unit 11 executes a search using the category or general name of the searched product as a search word. This search word may be registered, for example, when a user registers the searched product, or may be determined by referring to the search word history used by a purchaser of the searched product to reach the product. Furthermore, multiple search words may be registered for one searched product. This configuration enables counterfeit products to be extracted efficiently with high accuracy, reducing the computational load and computation time.

[0037] In some cases, multiple product images are linked to one product sales page. In this case, the extraction processing unit 11 may perform an image search on the multiple product images. The extraction processing unit 11 may also perform an image search on the images displayed on the search result screen.

[0038] The product search by the extraction processing unit 11 is performed using an algorithm similar to the search algorithm used by a purchaser attempting to make a purchase on a shopping mall. Purchasers generally purchase products after searching on a shopping mall, and this configuration makes it possible to extract products suspected of being counterfeit from the product images displayed on the screen that the purchaser actually views.

[0039] The discrimination processing unit 12 executes a discrimination process for discriminating whether or not a predetermined product is listed as inappropriate, based on the listing information extracted by the extraction processing unit 11.

[0040] In one example of a specific aspect, the discrimination processing unit 12 determines whether or not there is an inappropriate listing based on the listing information and whether or not there is an inappropriate listing by referring to the whitelist, depending on whether or not there is an listing by a seller other than an appropriate seller of a specific product. That is, if there is a seller other than a seller listed on the whitelist on the product sales page, it determines that there is an inappropriate listing.

[0041] In another example of a specific aspect, the discrimination processing unit 12 determines whether or not an inappropriate listing has been made based on the listing information, by referring to the whitelist, and by determining whether or not a cart has been acquired from a seller other than an appropriate seller of a predetermined product. That is, if a cart has been generated on the product sales page for an item listed by a seller other than a seller listed on the whitelist, it is determined that an inappropriate listing has been made. The determination processes given as specific examples of the embodiments may be performed selectively or in combination.

[0042] Furthermore, the discrimination processing unit 12 may refer to the product identification information included in the whitelist and determine whether the product identification information is recognized by the user based on the product identification information of the product extracted by the image search of the extraction processing unit 11. This is because a product that has been extracted by the image search but is given product identification information that is not included in the whitelist is likely to be a counterfeit product.

[0043] The notification processing unit 13 executes a notification process for notifying the user terminal 3 of the user who is the provider of the predetermined product of an inappropriate listing. The notification to the user may be made on the service site, or via other services such as chat tools or SNS, or via email, etc. In addition, the notification to the user may be performed only when an inappropriate listing is found, or the user may be notified of the determination result each time the determination process is performed, regardless of whether or not an inappropriate listing is found.

[0044] The notification processing unit 13 may also notify the user of the URL of a product sales page for a product that has been extracted by the image search but has product identification information that is not included in the whitelist. In this case, the notification method may vary depending on the similarity in the image search. For example, the product images may be listed in descending order of similarity and transmitted to the user terminal 3. The notification processing unit 13 may also notify the user of information about the site from which the URL is accessed. The site from which the URL is accessed may be, for example, an SNS. In addition, if the access is from a service site that displays a product purchase URL by photographing the product, the notification processing unit 13 may notify the user of information identifying the service site that links the product image information with the purchase URL.

[0045] Furthermore, the notification control unit 13 may issue a notification to the seller of an inappropriate item instead of or in addition to notifying the user terminal 3. The notification control unit 13 may send a message to the seller of an inappropriate item, for example, requesting the seller to withdraw the item. The notification control unit 13 may send the message via a platform provided by the shopping mall site, or may refer to the seller's information and send an email or a direct message on an SNS. The seller information may be obtained by extraction using an API, etc. Additionally, the notification control unit 13 may have a configuration for notifying the operator of the shopping mall site.

[0046] The communication processing unit 14 is a functional unit for executing transmission and reception of information via a network NW such as the Internet. The communication processing unit 14 enables the monitoring system 1 to access a shopping mall site to extract information and transmit information to the user terminal 3.

[0047] The mall management server 2 accepts listings of multiple products from multiple sellers. The mall management server 2 also manages the purchase screens for the listed products and displays the purchase screens on the terminals of buyers in response to operations from the terminals. The mall management server 2 manages information on products purchased through the shopping mall site and information on the buyers who made the purchases.

[0048] The user terminal 3 is a provider of a predetermined product, a terminal used by a user of the monitoring service, and is configured to be able to communicate with the monitoring system 1 via the network NW. The user terminal 3 may be realized by a so-called personal computer or a smart device such as a tablet terminal or a smartphone, and includes an information input / output unit, a browser program for transmitting and receiving information, and the like. Using this user terminal 3, the user can obtain information on the service site relating to the seller of a particular product, and can receive notification from the monitoring system 1 that an inappropriate product has been listed.

[0049] The seller terminal 4 is a terminal used by a seller who sells a predetermined product on the shopping mall site, and is configured to be able to communicate with the mall management server 2 via the network NW. Like the user terminal 3, the seller terminal 4 may be realized by a so-called personal computer or a smart device such as a tablet terminal or smartphone, and is equipped with an information input / output section and a browser program for transmitting and receiving information. The seller uses the seller terminal 4 to access the mall-type shopping site and list the product.

[0050] The purchase screen displays the product name, a description of the product, advertisements for other products related to the product, reviews of the product, default seller information, and so on. However, the display on the purchase screen is created and edited by the mall management server 2, and is changed from time to time as new sellers list products and buyers post reviews. Advertisements for other products are also changed from time to time as new advertisers enter the market, existing advertisers invest advertising funds, and advertisers change the images they display. Furthermore, the purchase screen is a screen that buyers always view when making a purchase decision. Therefore, a configuration in which the extraction processing unit 11 acquires purchase screen information allows buyers to review the screens they viewed at the time of purchase, thereby enabling them to properly understand the circumstances surrounding the purchaser's decision to purchase.

[0051] Here, the extraction processing unit 11 may periodically acquire information on the purchase screen, and when it detects a change in the purchase screen, the discrimination processing unit 12 may execute a discrimination process to determine whether or not an inappropriate listing has been made for a predetermined product. Alternatively, it may be further determined from the change in the purchase screen whether or not there has been a change in the listing status, and when there has been a change in the listing status, the discrimination processing unit 12 may execute a discrimination process to determine whether or not an inappropriate listing has been made for a predetermined product.

[0052] ●Processing flow (1) Next, the flow of processing by the monitoring system 1 according to this embodiment will be described with reference to FIG. When a predetermined timing, such as a fixed cycle, arrives (S101), the monitoring system 1 accesses the shopping mall site and extracts the listing information of a predetermined product by the extraction processing unit 11 (S102).

[0053] The determination processing unit 12 determines whether or not there is an inappropriate listing for a predetermined product based on the listing information extracted by the extraction processing unit 11 (S103). Specifically, based on the listing information, the whitelist is referenced to determine whether or not an inappropriate listing has been made based on whether or not a specific product has been listed by a seller other than an appropriate seller, or whether or not a specific product has been acquired from a cart by a seller other than an appropriate seller.

[0054] If, as a result of the determination, a product is listed on the product sales page by a seller other than those listed on the whitelist, or if a seller other than those listed on the whitelist has acquired a cart, the notification processing unit 13 will notify the user that an inappropriate listing has been made (S104).

[0055] The notification to the user may be made on the user's page (so-called "my page") on the service site, or may be made via other services such as chat tools or SNS, or via email, etc. In addition, in the processing illustrated in Figure 4, the user is notified only when it is determined that a specific product is being offered for sale by a seller other than an appropriate seller, but this is not limited to this, and the user can also be notified of the determination results each time.

[0056] A user who becomes aware of a listing of a specific product by an inappropriate seller through the monitoring system 1 can request the site operator of the mall-type shopping site to correct the listing situation or directly warn the inappropriate seller. Note that the user's response to such inappropriate sellers may be carried out on behalf of the user by a monitor operating the monitoring system 1. In this case, for example, the monitoring system 1 may send a notice to the mall management server 2 requesting that the listing be restricted along with information on the specified product and the inappropriate seller, or may send a notice to the seller terminal 4 of the inappropriate seller requesting that the listing be restricted.

[0057] ●Processing flow (2) Next, another example of the flow of processing by the monitoring system 1 according to this embodiment will be described with reference to FIG. When a predetermined timing, such as a fixed cycle, arrives (S201), the monitoring system 1 searches the shopping mall site using a predetermined search word (S202). Next, the extraction processing unit 11 performs an image search based on the product images displayed in the search results, and extracts product sales pages suspected of being resold or counterfeit products (S203).

[0058] Next, the discrimination processing unit 12 determines whether the product identification information of the product sales page extracted in S203 is on the whitelist (S204), and if it is not on the whitelist, the notification processing unit 13 notifies the user (S205).

[0059] If the item is listed on the whitelist in S204, the whitelist is referenced based on the listing information, and the presence or absence of inappropriate listings is determined based on whether or not there are listings by sellers other than appropriate sellers of the specified item (S205). Also, similar to S103 of Fig. 4, the presence or absence of inappropriate listings may be determined based on whether or not there are carts acquired by sellers other than appropriate sellers of the specified item.

[0060] If, as a result of the determination, a product is listed on the product sales page by a seller other than those listed on the whitelist, or if a seller other than those listed on the whitelist has acquired a cart, the notification processing unit 13 will notify the user that an inappropriate listing has been made (S206).

[0061] In S206, the notification method may be different depending on whether the product identification information is not on the whitelist in the processing of S204 or the seller is not on the whitelist in the processing of S205.

[0062] The monitoring system 1 according to the present embodiment monitors whether a predetermined product is being offered on a shopping mall by a vendor not recognized by the product's original supplier, and can prevent transactions of the predetermined product by inappropriate sellers. As a result, it is possible to prevent resale products, parallel imports, or inferior counterfeit products from being sold to users of the shopping mall. In particular, product providers can easily grasp the status of products on mall-type shopping sites that are not operated by the company, without much effort, and can ensure safe and fair transactions of the products they offer.

[0063] Other embodiments In a monitoring system according to another embodiment of the above-mentioned monitoring system 1 (hereinafter referred to as "monitoring system 5" for ease of explanation), the discrimination processing unit 12 can also determine whether or not there are any inappropriate products by comparing the price of a specified product being put up for sale with a specified fair price.

[0064] Such a determination process by the determination processing unit 12 is possible based on information relating to the price set by the seller for a specified product, among the listing information extracted from the mall management server 2 by the extraction processing unit 11. The predetermined fair price may be one that can be set by the user on the service site, or may be a value with a certain range based on the average price set for a predetermined product on a mall-type shopping site over a certain period of time.

[0065] The determination process in the monitoring system 5 according to this embodiment can be executed in appropriate combination with the determination process in the monitoring system 1 described above. [Explanation of symbols]
