  The storage unit 2 is configured by, for example, a hard disk drive or the like, and stores various programs such as an operating system and a fraud evaluation determination processing program. For example, the fraud evaluation determination processing program may be acquired from another server device or the like via the network NW, or may be recorded on a recording medium and read via the drive device. .

  In addition, the storage unit 2 stores a structured document (for example, an HTML (Hyper Text Markup Language) document or an XHTML document) file that constitutes a Web page, image data, and the like.

  Further, the storage unit 2 includes a user information database (DB) 21, an authentication information database (DB) 22, a basic delivery period information database (DB) 23 (an example of delivery period information storage means), an auction database (DB) 24, An evaluation information database (DB) 25 (an example of evaluation information storage means) and an unauthorized suspicion list database (DB) 26 (an example of unauthorized suspicion number storage means) are constructed. The user information database 21 and the auction database 24 are examples of commercial transaction information storage means.

  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 basic delivery period information database 23 shown in FIG. 3C, any one of the area ID of the product delivery source area (an example of the base) and the delivery period Pn (n = a, b, c, d... (2) Area information (an example of delivery period information) is registered in association with each area. Here, the area ID is identification information for identifying an area. Areas include, for example, Hokkaido, Northeast North (Aomori, Akita, Iwate), South Tohoku (Miyagi, Yamagata, Fukushima), Kanto (Tokyo, Kanagawa, Saitama, Chiba, Ibaraki, Tochigi, Gunma, Yamanashi), Shinetsu (Nagano) , Niigata), Hokuriku (Toyama, Ishikawa, Fukui), Chubu (Shizuoka, Aichi, Gifu, Mie), Kansai (Kyoto, Shiga, Nara, Wakayama, Osaka, Hyogo), China (Okayama, Hiroshima, Yamaguchi, Tottori, Shimane) ), Shikoku (Kagawa, Tokushima, Kochi, Ehime), Kyushu (Fukuoka, Oita, Saga, Nagasaki, Kumamoto, Miyazaki, Kagoshima) and Okinawa. It should be noted that how to divide the area can be arbitrarily set by an administrator or the like. For example, the area may be set in units of prefectures, cities or counties.

  In addition, the area information of the delivery period Pn indicates a delivery destination area in the delivery period Pn from the delivery source area. For example, if the delivery source area is Kanto, the area information of the delivery period Pa (for example, Pa = 2 days) indicates South Tohoku and Shinetsu, and the area of the delivery period Pb (for example, Pb = 3 days) The information shows northeast north, Hokuriku, Chubu, Kansai, and China, and the area information of the delivery period Pc (for example, Pc = 4 days) shows Shikoku, Kyushu, and Hokkaido, and the delivery period Pd ( For example, Okinawa is indicated in the area information of (Pd = 5 days). Note that the number of registered area information for the delivery period Pn differs depending on the delivery source area.

  By referring to the information registered in the basic delivery period information database 23 as described above, the delivery periods of products between a plurality of areas can be known.

  In the auction database 24 shown in FIG. 3D, an auction ID (an example of commercial transaction identification information), 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) ), Product image data, etc.), start price, immediate drop price, lowest successful bid price, number of items exhibited, exhibition start date / time, exhibition end date / time, number of times of automatic re-exhibition, presence / absence of automatic extension, etc. .

  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 area information of the delivery source of the successful bid product, the area information of the delivery destination of the successful bid product, the successful bid price, the successful bid number of the product, and the successful bid The date and time (the date and time when the business transaction was established) and the like are included. Here, the area information of the delivery source of the successful bid product is an example of the delivery source information related to the base of the delivery source of the product for which the commercial transaction has been established, and for example, the area specified from the address of the exhibitor is indicated. The area of the delivery destination of the product for which a successful bid is made is an example of delivery destination information relating to the base of the delivery destination of the product for which the commercial transaction has been completed. For example, the area specified from the address of the successful bidder is shown. Since the addresses of the exhibitor and the successful bidder are registered in the user information database 21, the successful bid information includes area information of the delivery source of the successful bid product and area information of the delivery destination of the successful bid product. It does not have to be included.

  In the evaluation information database 25 shown in FIG. 3E, a user ID and cumulative evaluation information are registered in association with each user. Here, the cumulative evaluation information includes an evaluation for a user from a trading partner in each past auction (evaluation when the user is an exhibitor and evaluation when the user is a successful bidder). Or one). For example, the cumulative evaluation information includes information such as 112 good evaluations, 4 normal evaluations, and 3 bad evaluations. With this cumulative evaluation information, the user's cumulative evaluation points can be calculated (for example, cumulative evaluation points = number of good evaluations−number of bad evaluations). The cumulative evaluation information includes evaluation comments and the like.

  The fraud suspicion list database 26 shown in FIG. 3 (F) corresponds to the seller's user ID, the number of fraud suspicions, the number of transactions (within one month), the number of transactions (cumulative), the average transaction price, the maximum transaction price, etc. Attached and registered. Here, the number of fraud suspicions is information indicating the degree of suspicion that the exhibitor has performed fraud evaluation, and the larger the number, the higher the suspicion of fraud.

  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 reads and executes the fraud evaluation determination processing program stored in the storage unit 2 by the CPU 4a, whereby the evaluation information receiving unit, the information acquiring unit, the evaluation date specifying unit, the evaluation period of the present invention Functions as a calculation unit, a delivery period specifying unit, a determination unit, a calculation unit, a threshold determination unit, an evaluation information update unit, an evaluation invalidation unit, a period determination unit, a number determination unit, and 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 with reference to FIG.

  FIG. 4 is a flowchart showing details of the evaluation information receiving process in the system control unit 4 of the auction processing server SA. The process shown in FIG. 4 is started after an article auction reception process, a bid reception process, and a successful bid process are performed in an auction. Since the exhibition acceptance process, the bid acceptance process, and the successful bid process are well known, the description thereof is omitted.

  In FIG. 4, the auction processing server SA performs an evaluation information setting screen (screen for setting an evaluation for an exhibitor) from the user terminal T1 after the login process of the user of the user terminal T1 connected via the network NW. In response to the request instruction, a web page having the evaluation information setting screen is transmitted to the user terminal T1 (step S1).

  When the user terminal T1 receives the web page having the evaluation information setting screen from the auction processing server SA, the web page is displayed on the display by the web browser. The user of the user terminal T1 operates the operation unit of the user terminal T1, and in the evaluation information setting column provided on the displayed evaluation information setting screen, the evaluation (for example, good) for the seller of the successful bid product and Set an evaluation comment or the like (for example, by entering it in the input field).

  Then, when the user operates the operation unit of the user terminal T1 to give an evaluation information transmission instruction (for example, clicks the evaluation information transmission button with a mouse), the evaluation information indicating the set evaluation and evaluation comment is displayed on the user terminal T1. To the auction processing server SA. The evaluation information includes a user ID and an auction ID in addition to information such as an evaluation and an evaluation comment set in the evaluation information setting field. The evaluation information may include information indicating an evaluation date.

  When the auction processing server SA receives the evaluation information from the user terminal T1 (step S2), the system control unit 4 selects the auction ID corresponding to the received evaluation information (in this example, the auction ID included in the evaluation information). ) Is acquired from the auction database 24 (step S3). The successful bid date information (an example of commercial transaction date information), the delivery source area information, and the delivery destination area information are displayed from the auction database 24.

  Next, the system control unit 4 specifies an evaluation date from the received evaluation information (step S4). For example, if the received evaluation information includes information indicating the evaluation date, the evaluation date is specified by acquiring the information. On the other hand, if the received evaluation information does not include information indicating the evaluation date, the date on which the evaluation information is received is specified as the evaluation date.

  Next, the system control unit 4 calculates an evaluation period from the successful bid date indicated in the successful bid date information acquired in step S3 to the evaluation date specified in step S4 (step S5). For example, the evaluation study days from the successful bid date to the evaluation date are calculated.

  Next, the system control unit 4 specifies the delivery period from the information registered in the basic delivery period information database 23 based on the area information of the delivery source and the area information of the delivery destination acquired in step S3 (step S6). . For example, if “Kanto” is indicated in the area information of the delivery source and “Hokkaido” is indicated in the area information of the delivery destination, according to the example shown in FIG. From the area information (including Hokkaido) of the delivery period Pc associated with the ID, the delivery period is specified as 4 days.

  Next, the system control unit 4 determines whether or not the evaluation period calculated in step S5 is shorter than the delivery period specified in step S6 (step S7). When the system control unit 4 determines that the evaluation period is shorter than the delivery period (step S7: YES), the system control unit 4 proceeds to step S8. In this case, since it is considered that the evaluation has been made even though the merchandise from the exhibitor has not yet arrived, it can be presumed that the exhibitor has suspected of performing the unauthorized evaluation. On the other hand, if the system control unit 4 determines that the evaluation period is not shorter than the delivery period (step S7: NO), the system control unit 4 proceeds to step S10. In this case, since it is considered that the evaluation was made after the merchandise from the exhibitor arrived, it can be estimated that the evaluation is valid by the successful bidder.

  In step S8, the system control unit 4 registers the seller's user ID (that is, the listing registered in association with the auction ID included in the evaluation information) to be evaluated in the evaluation information received in step S2. The user's user ID) is obtained from the auction database 24, and the number of fraud suspicions registered in the fraud suspicion list database 26 in association with the acquired seller's user ID is increased by a predetermined number (for example, 1) (for example, , Overwrite storage). If the number of fraud and suspicion corresponding to the seller's user ID has not been registered yet, the user ID and the number of fraud and suspicion “1” are newly registered in the fraud and suspicion list database 26.

  Next, the system control unit 4 determines whether or not the number of fraud suspicions increased by a predetermined number exceeds a threshold value (for example, 3) (step S9). If the system control unit 4 determines that the number of fraud and suspicion does not exceed the threshold (step S9: NO), the system control unit 4 proceeds to step S10, and determines that the number of fraud and suspicion exceeds the threshold. (Step S9: YES), the process proceeds to Step S11.

  In step S10, the system control unit 4 uses the seller's user ID (that is, the seller's user ID registered in association with the auction ID included in the evaluation information) based on the evaluation information received in step S2. ) And the accumulated evaluation information registered in the evaluation information database 25 is updated. For example, when the evaluation shown in the received evaluation information is “good”, the number of good evaluations included in the cumulative evaluation information registered in the evaluation information database 25 is incremented by “1” and received. The evaluation information evaluation comments are added to the cumulative evaluation information. In this way, the updated cumulative evaluation information and the cumulative evaluation points calculated based on the updated cumulative evaluation information are provided to all user terminals Tn that have accessed the auction site together with the user ID and nickname of the seller and viewed by each user. It becomes possible.

  In step S11, the system control unit 4 executes processing for invalidating the evaluation indicated in the evaluation information received in step S2. In other words, when the number of fraud suspicions exceeds the threshold value, it is considered that the seller has performed a fraud evaluation, and the evaluation indicated in the evaluation information is not reflected in the accumulated evaluation information registered in the evaluation information database 25.

  As described above, according to the above embodiment, the auction processing server SA determines whether or not the evaluation period (evaluation days) is shorter than the delivery period in a certain auction, and if the evaluation period is shorter than the delivery period. When the determination is made, the number of fraud suspicions registered in the fraud suspicion list database 26 in association with the user ID of the exhibitor at the auction is increased by a predetermined number, so that one user has a plurality of suspicions. Even if a product that has a user ID and has been submitted using a user ID for the user and made a successful bid and fraud evaluation in a short period of time using another user ID, fraud evaluation (unauthorized lifting of evaluation) ) Can be accumulated in association with the exhibitor's user ID.

  If the auction processing server SA determines that the number of fraud and suspicion increased by a predetermined number exceeds the threshold, the evaluation indicated in the evaluation information is not reflected in the accumulated evaluation information registered in the evaluation information database 25. Therefore, fraud evaluation can be effectively reduced.

  When the number of fraud suspicions exceeds the threshold value in step S9, the system control unit 4 registers the seller user ID registered in association with the auction ID included in the evaluation information in the unauthorized user list. By doing so, you may comprise so that the said user's participation (bidding or exhibition) in the auction after the next time may be restrict | limited. 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. 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 an exhibitor performs a fraud evaluation, the number of fraud suspicions is linked to and stored in the user ID of the seller, and the number of fraud suspicions exceeds a threshold. If it is configured so as to restrict participation in the auction after the next time, it is possible to effectively encourage the seller to perform unauthorized evaluation.

  If the system control unit 4 determines in step S7 shown in FIG. 4 that the evaluation period is shorter than the delivery period, the system control unit 4 uses, for example, an Internet service provider server for the user terminal T1 that is the transmission source of the evaluation information. Only when the assigned IP address (an example of the unique information of the terminal device) is included in the list of IP addresses of sellers to the auction corresponding to the evaluation information stored in the storage unit 2 in advance, the process proceeds to step S8. You may advance and increase the number of fraud suspicions. 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 Tn are registered in this list. Yes. That is, the fraud suspicion number is increased only when the IP address of the exhibitor's user terminal Tn matches the IP address of the successful bidder's user terminal Tn. Thereby, fraud evaluation can be reduced effectively while improving the accuracy of determination as to whether or not the user has performed fraud evaluation. In the IP address list, IP addresses assigned to the user terminals Tn that have been subjected to fraud evaluation 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 since the reference time for each user ID of the seller registered in the fraud suspicion list database 26. 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 26 (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 26 or when the number of fraud suspicions in the fraud suspicion list database 26 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 the system control part 4 will be, if the user ID corresponding to the said number of fraud suspicion is registered into the fraudulent user list, when the number of fraud suspicion decreased by the predetermined number as mentioned above becomes below a threshold value The user ID is deleted from the unauthorized user list. According to such a configuration, since it is determined whether or not the user has performed the fraud evaluation with information within the latest limited period, the fraud evaluation is effectively reduced while improving the accuracy of the determination. be able to.

  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 26 is a predetermined number (for example, 10 times) or more, and the predetermined number 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 26 (exhibitors determined to have exceeded the predetermined number of times) may be reduced by a predetermined number.
