Description

    The present invention relates to an auction processing device that performs processing related to an auction in response to a request from an exhibitor terminal device used by an auction seller and a bidder terminal device used by a bidder to the auction. Relates to the field of technology.

  In recent years, auctions held at auction sites on the Internet have become widespread. A user who has gone through the procedure for using the auction site can access the auction site from his / her terminal device and perform an auction or bidding.

  In such an auction, there is a problem of illegally raising the bid price. As a method of restricting unauthorized lifting of the bid price, a user ID of a user who raises the bid price illegally (hereinafter referred to as “illegal user”) is registered in an unauthorized user list (black list), and bidding from the unauthorized user is performed. There are known ways to limit the above. As another method, a method has been proposed in which a bid right is stripped from a client whose bid price is higher and auction is continued only by other clients (Patent Document 1).

JP 2003-6472 A

  However, in the conventional method described above, each time an unauthorized user holds a plurality of user IDs and knows that the user ID has been registered in the unauthorized user list for each bid, the user ID used at the time of previous bidding When bidding is performed using a different new user ID, the new user ID is not registered in the unauthorized user list, and thus unauthorized bidding cannot be restricted. Further, in the method disclosed in Patent Document 1, since the bid right is deprived only because the bid price is higher, the significance as the originally intended auction may be impaired.

  The present invention has been made in view of the above problems, and an unauthorized user has a plurality of user IDs and makes a bid using a new user ID different from the user ID used at the time of previous bidding. Even if it is done, it is possible to accumulate the acts (number of times) that are alleged to be fraudulent bids (lifting bid prices) in association with the seller's user ID, effectively reducing fraud bids. An object is to provide a possible auction processing device, an auction processing method, and an auction processing program.

  Further, the storage unit 2 includes a user information database (DB) 21, an authentication information database (DB) 22, an auction database (DB) 23 (an example of second storage means), a commodity price information database (DB) 24, fraud and allegations. A list database (DB) 25 (an example of a first storage unit) and an unauthorized user list database (DB) 26 are constructed.

  FIG. 3 is a diagram illustrating an example of contents registered in various databases.

  The user information database 21 shown in FIG. 3A includes a user ID, a nickname, a name, a gender, an address, a telephone number, of a user who is registered as an auction member (an auction seller, a user who can be a bidder). In addition, user information such as an email address is registered (stored) in association with each user. The user ID is identification information for identifying a user as a member.

  In the authentication information database 22 shown in FIG. 3B, a user ID, a login ID, and a password are registered in association with each user. The login ID and password are authentication information used for a login process (user authentication process) for participating in an auction (exhibition or bidding).

  In the auction database 23 shown in FIG. 3C, an auction ID, exhibition information, bid information, and successful bid information are registered in association with each auction.

  Here, the auction ID is identification information for identifying an auction of a certain product.

  The exhibition information includes, for example, the seller's user ID (an example of seller identification information), the nickname of the seller, the product information of the product that has been exhibited (for example, the name of the product, the genre of the product, the description of the product (product) ), Starting price (starting price), immediate drop price, lowest successful bid price, number of listings, listing start date / time, listing end date / time, automatic re-listing count, and whether or not there is automatic extension Etc. are included. The minimum successful bid price is a desired bid price to be secured as a minimum set by the exhibitor. However, a bidder cannot be qualified unless the bid price is higher than this price. This minimum successful bid price is an example of a set price set for a product for sale at the auction. Note that the lowest successful bid price may not be set depending on the seller or the auction processing system.

  The bid information includes, for example, the user ID of the bidder, the nickname of the bidder, the bid price, the number of bids for the product, and the bid date and time.

  The successful bid information includes, for example, the user ID of the successful bidder, the nickname of the successful bidder, the successful bid price, the number of successful bids for the product, and the successful bid date and time.

  In the product price information database 24 shown in FIG. 3D, product price information, a product classification code, and a classification keyword are registered in association with each product classification.

  Here, the products in the database 24 include not only products that have been exhibited in the auction, but also products that have been sold in the past and products that are currently being sold at shopping sites and the like. These products are classified by classification keywords such as name, genre (clothes, electrical equipment, food, etc.), specifications (color, size, type, etc.), and the same product classification code is used for the same or similar products. Is granted. The same product is, for example, a product whose name, genre, and specification match. On the other hand, a similar product is, for example, a product in which at least part of the name and at least part of the specification match and the genre matches.

  The price information of the product includes, for example, the highest bid price or the average successful bid price among a plurality of products (same or similar products) that belong to the same product category and have been exhibited in the auction in the past. The price information of the product includes, for example, the highest selling price or the average selling price (commodity market price) among a plurality of products that belong to the same product category and have been sold in the past or currently on a shopping site. Price). Note that the highest successful bid price, average successful bid price, highest selling price, or average selling price is used as a set price that is set for a product displayed in an auction.

  In the fraud and suspicion list database 25 shown in FIG. 3E, the user ID of the exhibitor and the number of fraud and suspicion of the exhibitor are registered in association with each other. Here, the number of fraud suspicions is information indicating the degree of suspicion of an unauthorized user, and the larger the number, the higher the suspicion of fraud.

  In the unauthorized user list database 26 shown in FIG. 3F, user IDs of unauthorized users are registered. An unauthorized user whose user ID is registered in the unauthorized user list database 26 is refused to participate in the auction (exhibition and bidding).

  The input / output interface unit 3 performs interface processing between the communication unit 1 and the storage unit 2 and the system control unit 4.

  The system control unit 4 includes a CPU (Central Processing Unit) 4a, a ROM (Read Only Memory) 4b, a RAM (Random Access Memory) 4c, and the like. Then, the system control unit 4 performs a Web page providing process by the CPU 4 a reading and executing the auction processing program stored in the storage unit 2. Further, the system control unit 4 includes an exhibition request receiving unit, a bid request receiving unit, a set price acquisition unit, a matching price determination unit, a calculation unit, a threshold determination unit, a limit processing execution unit, a period determination unit, and a number determination unit according to the present invention. It functions as a means or the like, and performs processing described later.

[2. Operation of the auction processing system]
Next, the operation of the auction processing system S according to the present embodiment will be described using FIG. 4 and FIG. It is assumed that the exhibitor and bidder described below are registered as members of the auction and have registered user information.

  FIG. 4 is a sequence diagram showing processing and information exchange between the user terminal Tn and the auction processing server SA. FIG. 5 is a flowchart showing details of the exhibition acceptance process in the system control unit 4 of the auction processing server SA. FIG. 6 is a flowchart showing details of bid acceptance processing in the system control unit 4 of the auction processing server SA.

  In FIG. 4, the auction processing server SA has an auction listing screen in response to a request instruction for the auction listing screen from the user terminal T1 after the login process of the user of the user terminal T1 connected via the network NW. The web page is transmitted to the user terminal T1 (step S1).

  When the user terminal T1 receives a web page having an auction listing screen from the auction processing server SA, the web page is displayed on the display by the web browser (step S2). The user who is an exhibitor operates the operation unit of the user terminal T1, and in the exhibition information setting column provided on the displayed screen for auction exhibition, product information, start price, immediate price, The lowest successful bid price, the number of items to be exhibited, the date and time of listing start, the date and time of listing end, the number of times of automatic relisting, the presence or absence of automatic extension, etc. are set (for example, entered in the input field or selected in the selection field). Note that the lowest successful bid price may not be set.

  Then, when the exhibitor operates the operation unit of the user terminal T1 to give an exhibition instruction (for example, clicks on the exhibition button with a mouse), the exhibition request information for the auction is sent from the user terminal T1 to the auction processing server SA. It is transmitted (step S3). The exhibition request information for the auction includes, for example, the user ID of the exhibitor, the nickname of the exhibitor, information set in the exhibition information setting field on the auction listing screen, and the like.

  When the auction processing server SA receives the exhibition request information for the auction from the user terminal T1, the system control unit 4 starts the exhibition acceptance process (step S4). In this exhibition acceptance process, as shown in FIG. 5, the system control unit 4 determines whether or not the user ID included in the received exhibition request information is registered in the unauthorized user list database 26 (step S41). . If the system control unit 4 determines that the user ID is registered in the unauthorized user list database 26 (step S41: YES), the system control unit 4 proceeds to step S42, and the user ID is registered in the unauthorized user list database 26. If it is determined that it is not (step S41: NO), the process proceeds to step S43.

  In step S <b> 42, the system control unit 4 transmits a Web page displaying information indicating the rejection of exhibition to the user terminal T <b> 1. Thereby, the exhibition by the seller is rejected. Whether or not the user ID is registered in the unauthorized user list database 26 is determined during the login process. If the user ID is registered in the unauthorized user list database 26, the login is rejected. Also good.

  In step S43, the system control unit 4 uses the information included in the received exhibition request information as exhibition information, and registers the exhibition information in association with the newly assigned auction ID in the auction database 23. The auction ID is numbered so as not to overlap with other auction IDs already registered in the auction database 23.

  Next, the system control unit 4 stores the product information (for example, name, genre, specification) of the product included in the received exhibition request information and the classification keyword (for example, name, genre, Specifications) and determine whether there is a product that is the same as or similar to the exhibited product (step S44). For example, if a classification keyword that matches product information (for example, a combination of name, genre, and specification) included in the received exhibition request information is registered in the product price information database 24, there is an identical product. Determined. Further, for example, classification keywords that match some but not all of the product information (for example, a combination of name, genre, and specification) included in the received exhibition request information are registered in the product price information database 24. In this case, it is determined that there is a similar product.

  And when it judges with system control part 4 having the same or similar goods (Step S44: YES), the goods classification code (namely, the above-mentioned received) corresponding to the same or similar goods as the exhibited goods The merchandise classification code registered in association with the classification keyword corresponding to all or part of the merchandise information of the merchandise included in the exhibition request information is included in the auction database 23 in the exhibition information registered in step S43. Register (step S45). In this way, a merchandise classification code is given to the exhibited merchandise. On the other hand, when it judges with system control part 4 not having the same or similar goods (Step S44: NO), processing shown in Drawing 5 is ended.

  It should be noted that the processing of steps S44 and S45 is not performed immediately after step S43, but may be configured to be performed at a predetermined time interval, for example, with respect to the products that have not yet been given the product classification code. good. Moreover, you may comprise so that provision of a merchandise classification code may be performed according to the instruction | indication from an operator, for example.

  Thus, the auction listing from the exhibitor is completed.

  Next, the auction processing server SA requests a screen for auction bidding from the user terminal T2 after the user login processing of the user terminal T2 (the user terminal T1 is also an unauthorized user) connected via the network NW. In response to the instruction, a web page having an auction bidding screen is transmitted to the user terminal T2 (step S5).

  Next, when the user terminal T2 receives a web page having an auction bidding screen from the auction processing server SA, the web page is displayed on the display by the web browser (step S6). The user who is a bidder operates the operation unit of the user terminal T2, searches the displayed auction bidding screen for a desired item for sale, and sets the bid price of the searched item for the auction bid. Set in the setting field of the bid price (bid amount) provided on the screen for use (for example, by inputting in the input field). At this time, the bidder can also set the bid quantity (bid quantity) of the desired product.

  Then, when a bidder operates the operation unit of the user terminal T2 to give a bid instruction (for example, clicks a bid button with a mouse), bid request information for an auction is sent from the user terminal T2 to the auction processing server SA. It is transmitted (step S7). The bid request information for the auction includes, for example, the auction ID, the bidder's user ID, the bidder's nickname, and the bid price set in the setting column on the auction bidding screen.

  When the auction processing server SA receives bid request information for the auction from the user terminal T2, the bid acceptance processing is started (step S8). In this bid acceptance process, as shown in FIG. 6, the system control unit 4 determines whether or not the user ID included in the received bid request information is registered in the unauthorized user list database 26 (step S81). . If the system control unit 4 determines that the user ID is registered in the unauthorized user list database 26 (step S81: YES), the system control unit 4 proceeds to step S82, and the user ID is registered in the unauthorized user list database 26. If it is determined that it is not (step S81: NO), the process proceeds to step S83.

  In step S82, the system control unit 4 transmits a web page displaying information indicating bid rejection to the user terminal T2. Thereby, the bid by the bidder is rejected. Whether or not the user ID is registered in the unauthorized user list database 26 is determined during the login process. If the user ID is registered in the unauthorized user list database 26, the login is rejected. Also good.

  In step S83, the system control unit 4 acquires the exhibition information associated with the auction ID (that is, the auction ID of the auction corresponding to the bid request information) included in the received bid request information from the auction database 23, that is, , Read into a predetermined area of the RAM.

  Next, the system control unit 4 determines whether or not the lowest successful bid price is included in the acquired exhibition information (step S84). If it is determined that the lowest successful bid price is included (step S84: YES), The process proceeds to step S85, and if it is determined that the lowest successful bid price is not included (step S84: NO), the process proceeds to step S86. When the lowest successful bid price is not included in the exhibition information, there is a case where the lowest successful bid price is not set depending on the exhibitor. In the first place, in the auction processing system in which the lowest successful bid price is not set, the processes of steps S84 and S85 are not performed, and the process proceeds from step S83 to step S86.

  In step S85, the system control unit 4 matches the bid price (bid price information) included in the received bid request information with the lowest bid price (set price information) included in the exhibition information acquired in step S83. Judge whether there is a degree. For example, it is determined whether or not the bid price is included within a range of ± predetermined value% of the lowest successful bid price. This predetermined value can be arbitrarily set by an operator, for example. Then, when the system control unit 4 determines that the degree of coincidence between the bid price and the lowest successful bid price is present (for example, when the bid price is included within ± 5% of the lowest successful bid price) (step S85). : YES), the process proceeds to step S89, and if it is determined that there is no match between the bid price and the lowest successful bid price (step S85: NO), the process proceeds to step S86. Note that when the bid price matches the lowest successful bid price, it may be determined that the degree of coincidence between the bid price and the lowest successful bid price is “Yes”. Further, when it is determined that the degree of coincidence between the bid price and the lowest successful bid price is not, the process may proceed to step S93.

  In step S86, the system control unit 4 determines whether or not the merchandise classification code is included in the exhibition information acquired in step S83. If the merchandise classification code is included (step 86: YES). The process proceeds to step S87, and if the product classification code is not included (step 86: NO), the process proceeds to step S93.

  In step S87, the system control unit 4 records the highest selling price (corresponding to the exhibited product or the same as the exhibited product) registered in association with the product classification code that matches the product classification code included in the exhibition information acquired in step S83. The maximum sales price of similar products) is acquired from the product price information database 24. Instead of the highest selling price, the highest winning bid price, the average winning bid price, or the average selling price may be acquired.

  Next, the system control unit 4 and the bid price included in the received bid request information and the highest selling price acquired in step S87 (may be the highest winning bid price, average winning bid price, or average selling price) (set price information) (Step 88). This determination method is the same as in step S85.

  Then, when the system control unit 4 determines that the degree of coincidence between the bid price and the maximum selling price is present (for example, when the bid price is within a range of ± 5% of the maximum selling price) (step S88). : YES), the process proceeds to step S89, and if it is determined that there is no match between the bid price and the lowest successful bid price (step S88: NO), the process proceeds to step S93. Note that, when the bid price matches the lowest successful bid price, if it is determined that the degree of coincidence between the bid price and the lowest successful bid price is determined, the accuracy of determining that there is fraud and suspicion can be improved.

  In step S89, the system control unit 4 makes an illegal association with the user ID of the seller included in the exhibition information acquired in step S83 (that is, the seller to the auction corresponding to the received bid request information). The number of fraud suspicions registered in the suspicion list database 25 is increased by a predetermined number (for example, 1) (for example, overwritten and stored). If the seller's user ID and fraud suspicion number included in the exhibition information acquired in step S83 have not yet been registered, the user ID and the fraud suspicion number “1” are newly added to the fraud suspicion list database 25. Registered in

  Here, the system control unit 4 determines that the degree of coincidence is present in step S85 (or step S88), and before performing the process of step S89, the start price included in the exhibition information acquired in step S83 is It is determined whether or not it is less than a predetermined ratio (for example, 5,000 × 50% if the set price is 5,000 yen) of the set price (the lowest successful bid price or the highest selling price, etc.). It may be configured to increase the number of fraud and suspicion only by a predetermined number. Thereby, in order to attract the attention of many users, illegal price lifting can be effectively suppressed for an exhibitor who intentionally starts from a low price.

  Next, the system control unit 4 determines whether or not the number of fraud suspicions increased by a predetermined number exceeds a threshold (for example, 3) (step S90). If the system control unit 4 determines that the number of fraud and suspicion exceeds the threshold (step S90: YES), the system control unit 4 proceeds to step S91, and determines that the number of fraud and suspicion does not exceed the threshold. (Step S90: NO), the process proceeds to Step S93.

  Here, the system control unit 4 increases the predetermined number of fraud suspicions in step S89, and before performing the determination process shown in step S90, the start price included in the exhibition information acquired in step S83 is the above setting. It may be configured to determine whether or not the price (the lowest successful bid price or the highest selling price) is equal to or lower than a predetermined ratio, and to perform the determination process shown in step S90 only when the price is equal to or lower than the predetermined ratio.

  In step S91, the system control unit 4 executes a restriction process for restricting a bid request related to the received bid request information. In other words, it is unnatural that the bid price and the lowest successful bid price coincide with each other many times even though it is not specified, so it is considered that the seller and the bidder are the same unauthorized user. . In this restriction process, the system control unit 4 rejects the bid by the bidder by transmitting, for example, a Web page displaying information indicating bid rejection to the user terminal T2.

  Next, the system control unit 4 executes a restriction process for restricting the participation of the exhibitor in the auction corresponding to the received bid request information from the next time onward (step S92). In this restriction process, the system control unit 4 registers the user ID of the seller included in the exhibition information acquired in step S83 in the unauthorized user list database 26, for example, so that the user can enter the next auction. Limit participation. Here, the restriction includes, for example, refusal to participate in the auction forever, refusal to participate in the auction for a certain period, and other new conditions for participating in the auction. The system control unit 4 may be configured to register the user ID of the bidder included in the received bid request information in the unauthorized user list database 26.

  In step S93, the system control unit 4 uses the bidder's user ID, bidder's nickname, bid price, etc. included in the received bid request information as bid information, and includes the bid information in the bid request information. Registered in the auction database 23 in association with the auction ID.

  Thus, the bidding for the auction from the bidder is completed. After that, the successful bid processing is performed by the system control unit 4, but the description is omitted because it is not directly related to the present invention.

  As described above, according to the above-described embodiment, the auction processing server SA determines the degree of coincidence between the lowest successful bid price set by the seller for the auction and the bid price set by the bidder for the auction. The presence / absence is determined, and when it is determined that there is a match, the number of fraud suspicions registered in the fraud suspicion list database 25 is increased by a predetermined number in association with the user ID of the seller at the auction. Therefore, even when an unauthorized user has a plurality of user IDs and makes a bid using a new user ID different from the user ID used at the time of previous bidding, The action (number of times) that is suspicious of being (lifting) can be stored in association with the user ID of the exhibitor.

  In addition, the auction processing server SA determines whether or not there is a degree of coincidence between the current or past highest selling price or the like of the same or similar product as the exhibited product and the bid price set by the bidder for the auction. When it is determined that the degree of coincidence exists, the number of fraud suspicions registered in the fraud suspicion list database 25 in association with the user ID of the exhibitor at the auction is increased by a predetermined number. Even if the lowest successful bid price is not set by the seller, it is possible to store the act that is suspicious of being an illegal bid in association with the user ID of the exhibitor.

  Then, when the auction processing server SA determines that the number of fraud suspicion increased by a predetermined number exceeds the threshold, the auction processing server SA rejects a bid request from a user determined to exceed the threshold, Since it is configured to restrict participation in the auction, it is possible to effectively reduce illegal bids.

  If an exhibitor who has made many exhibits takes appropriate measures at the time of a successful bid, generally, the seller's evaluation will be high and the user ID and nickname of the seller will be credited with other users. Therefore, as an exhibitor, the user ID and nickname should not be discarded. When such a seller makes an illegal bid, the number of fraud suspicions is accumulated in the user ID of the seller and the number of fraud suspicions exceeds a threshold. Since the participation in the auction after the next time is restricted, it is possible to effectively make the exhibitor make an illegal bid.

  In the above embodiment, only when the initial bid price is for the exhibited product (that is, only when the bid request information is initially received for the exhibited product), the processes in steps S84 to S92 are performed. If it is not the initial bid price for the exhibited product, the process may be shifted from step S83 to step S93. The reason for configuring in this way is that it is assumed that unauthorized users tend to tender themselves sooner than others for the purpose of raising the bid price after listing. However, since it may be assumed that the bid price is not raised earlier than others for the purpose of raising the bid price, if the bid is within a predetermined number of times (for example, 2 to 5 times) for the exhibited item, the above steps S84 to S92 are performed. If the bid is over a predetermined number of times for the product that has been processed, the process may proceed from step S83 to step S93. Thereby, the illegal price raising after the bid by other users can be suppressed effectively.

  In step S85 shown in FIG. 6, when the system control unit 4 determines that the degree of coincidence between the bid price and the lowest successful bid price is, for example, an Internet service is provided to the user terminal T2 that is the source of the bid request information. When the IP address assigned by the provider's server (an example of the unique information of the terminal device) is included in the IP address list of the seller for the auction corresponding to the bid request information stored in the storage unit 2 in advance. Only in step S89, the number of fraud suspicions may be increased. Here, the IP address list is stored in association with the seller's user ID, and a plurality of IP addresses previously assigned to the seller's user terminal T1 are registered in this list. Yes. That is, only when the IP address of the exhibitor's user terminal Tn matches the IP address of the bidder's user terminal Tn, the number of fraud suspicions is increased. It is possible to effectively reduce fraudulent bids while improving the accuracy of determining whether or not the user is an unauthorized user. In the IP address list, IP addresses assigned to the user terminals Tn that have been illegal in the past may be registered.

  In the above embodiment, the system control unit 4 determines whether or not a predetermined period (for example, two years) has elapsed from the reference time for each seller user ID registered in the fraud and suspicion list database 25. When it is determined periodically and it is determined that the predetermined period has passed, the number of fraudulent suspicions of the sellers registered in the fraud and suspicion list database 25 (exhibitors determined to have passed the predetermined period) is decreased by a predetermined number. You may comprise so that it may be made. Here, examples of the reference time include when the user ID and the fraud suspicion number are registered in the fraud suspicion list database 25 or when the number of fraud suspicions in the fraud suspicion list database 25 has been decreased by a predetermined number. It is done. Note that the predetermined number can be set to an arbitrary number equal to or less than the number of fraud and suspicion, and may be configured to decrease by the number of fraud and suspicion (that is, to set the number of fraud and suspicion to 0). And when the number of fraud suspicion decreased by a predetermined number as described above becomes equal to or less than the threshold, the system control unit 4 registers the user ID corresponding to the number of fraud suspicion in the unauthorized user list database 26. If there is, the user ID is deleted from the unauthorized user list database 26. According to such a configuration, since it is determined whether or not the user is an unauthorized user based on information within the latest limited period, it is possible to effectively reduce unauthorized bidding while improving the accuracy of the determination.

  Alternatively, the system control unit 4 determines whether or not the number of exhibitions by the seller corresponding to the user ID registered in the fraud and suspicion list database 25 is a predetermined number (for example, 10 times) or more, and the predetermined number of times or more. When it is determined that it has become, the number of fraudulent suspicions of exhibitors registered in the fraud and suspicion list database 25 (exhibitors determined to have exceeded the predetermined number of times) may be reduced by a predetermined number. Here, the number of exhibitions by each exhibitor can be calculated from information registered in the auction database 23. And the system control part 4 deletes the said user ID from the unauthorized user list database 26 similarly to the above, when the number of fraud suspicion decreased by the predetermined number becomes below a threshold value. According to such a configuration, since it is determined whether the user is an unauthorized user in consideration of the number of exhibitions without limiting the period, an unauthorized user who exhibits several times a year, for example, while improving the accuracy of the determination. Can effectively limit unauthorized bidding.
