To provide a server device etc. capable of concluding a transaction with the consent of a purchaser even if an appraisal result shows that appraisal is impossible. [Solution] When a target product with a two-dimensional code affixed thereto is delivered to an appraiser, a product information providing unit 243 provides product information about the target product to the appraiser terminal in response to the two-dimensional code read by the appraiser terminal. An appraisal result acquisition unit 244 acquires an appraisal result based on the target product and the product information from the appraiser terminal. If the appraisal result indicates that appraisal is not possible, an appraisal management unit 245 inquires of the purchaser terminal as to whether or not to continue the commercial transaction related to the target product, and if the answer is yes, concludes the commercial transaction and instructs the appraiser terminal to send the target product to the purchaser.

Description

[Technical field]

[0001] The present invention relates to a server device, an appraisal management method, and a program. [Background technology]

[0002] In recent years, services such as flea markets and auctions via the Internet have become widespread. For example, in a flea market service, sellers set a price for their products, along with detailed descriptions and photos, and then list the products. If a buyer wishes to purchase a listed product, they can purchase the product as is if they are satisfied with the set price, and if they wish to negotiate the price (such as for a lower price), they can exchange messages with the seller.

[0003] In these flea markets, auctions, and other services, there are cases where non-genuine products (counterfeits or imitations) are put up for sale. When a customer purchases a product they thought was genuine, but it turns out to be a counterfeit or imitation, this can easily lead to serious trouble between the seller and the customer.

[0004] In order to prevent such troubles, Patent Document 1 discloses an invention of an authenticity determination system that can properly determine the authenticity of an item. Also, Non-Patent Document 1 discloses an auction service that allows users to request free authentication of high-value trading cards. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-86573 A [Non-patent literature]

[0006] [Non-Patent Document 1] "Yahoo! Auctions starts offering a service that allows users to request free authentication when listing high-value trading cards," [online], 2023, Yahoo Japan Corporation, [searched January 30, 2024], Internet<URL:https: / / about.yahoo.co.jp / pr / release / 2023 / 08 / 31b / > Summary of the Invention [Problem to be solved by the invention]

[0007] In the authenticity determination system described in Patent Document 1, multiple appraisers each perform appraisal based on image information, video information, etc. of the listed product. The purchasing user can then refer to appraisal information that includes the appraisal results of each appraiser. Nevertheless, in the authenticity determination system described in Patent Document 1, the appraiser appraises the product based on image information, video information, etc., rather than the actual product, so that it is possible that some products may not be adequately appraised. Furthermore, if a listing user who provides image information, video information, etc. of a genuine product delivers a counterfeit or imitation product that is different from the genuine product to the purchasing user, the appraisal results by the appraiser users will be meaningless. On the other hand, in the auction service described in Non-Patent Document 1, the successful bidder delivers the trading card itself from the seller to an appraisal company for appraisal. The trading card that has been appraised as genuine by the appraisal company is then delivered by the appraisal company to the successful bidder.

[0008] In the auction service described in Non-Patent Document 1 mentioned above, the items to be appraised are mostly trading cards that appraisers can determine to be real (genuine) or fake (counterfeit or imitation). However, in the case of products such as brand-name goods and novelty goods, appraisers are often unable to determine whether they are genuine or counterfeit, and are forced to decide that they cannot be authenticated. For example, some companies that conduct global business handle a mixture of globally distributed products and locally distributed products. In particular, since locally distributed products are produced independently in that country (for example, Japan), situations may arise where the headquarters of the home country (for example, a country other than Japan) cannot grasp all of the products. For example, while Japanese appraisal companies can appraise products that are sold globally or that are sold locally in Japan, they are forced to determine that they cannot appraise products that are parallel imports of products sold locally in countries other than Japan.

[0009] For this reason, for example, if one were to apply this technology to a flea market service based on the technology of the above-mentioned non-patent document 1 and include brand-name products, novelty goods, and other items in the items to be appraised, there would be a certain percentage of items that the appraiser would determine cannot be appraised, and there would be a concern that the transaction would be canceled. This situation not only means that sellers who own legitimate products lose sales opportunities, but also that buyers who are knowledgeable about brand-name products lose an opportunity to purchase legitimate products.

[0010] Given this situation, there was a need for technology that would allow a transaction to be concluded with the purchaser's consent even if the appraisal by the appraiser was found to be inappropriate.

[0011] The present invention has been made in consideration of the above-mentioned situation, and aims to provide a server device, an appraisal management method, and a program that can complete a transaction with the purchaser's consent even if the appraisal result of the appraiser is that the appraisal is inapplicable.

[0024] An embodiment of the present invention will be described below. In the embodiment of the present invention, a flea market system that provides a flea market service via the Internet will be described as an example, but the present invention is not limited to such a flea market service and can also be applied to an auction system that provides an auction service, etc. In other words, the following embodiments are for illustrative purposes only and do not limit the scope of the present invention. Therefore, a person skilled in the art can adopt embodiments in which each or all of these elements are replaced with equivalents, and these embodiments are also included in the scope of the present invention.

[0025] (Overall composition) A flea market system 100 according to an embodiment of the present invention is a system that manages commercial transactions between sellers and purchasers, and, if an item purchased by a purchaser is a target item to be appraised, has the target item delivered from the seller to an appraiser. As shown in FIG. 1, the system is configured to include a server device 200, a seller terminal 300, a purchaser terminal 400, and an appraiser terminal 500. The server device 200, the seller terminal 300, the purchaser terminal 400, and the appraiser terminal 500 are communicatively connected via the Internet 900. Although Fig. 1 shows one seller terminal 300 and one purchaser terminal 400, this is for ease of understanding the invention, and in reality, a huge number of seller terminals 300 and purchaser terminals 400 are included depending on the number of users using the flea market system 100. Also, a plurality of appraiser terminals 500 may be included.

[0026] The server device 200 is, for example, a server computer that manages products offered for sale by the seller terminal 300 (seller) and also accepts purchases of products (including purchase requests, etc.) from the buyer terminal 400 (purchaser), thereby supporting commercial transactions between the seller and the buyer. In addition, when the put-up item is a target item that is subject to appraisal, such as a brand-name item, and a buyer who intends to purchase the target item wishes to have it appraised, the server device 200 instructs the seller to deliver the target item to an appraisal company.

[0027] The seller terminal 300 is, for example, a smartphone, tablet terminal, PC (Personal Computer), or the like having communication and camera functions, and is used by sellers who offer goods on the flea market system 100.

[0028] The purchaser terminal 400 is, for example, a smartphone, tablet terminal, PC, or the like having a communication function and a camera function, and is used by a purchaser who purchases products put up for sale in the flea market system 100.

[0029] The appraiser terminal 500 is, for example, a smartphone, tablet terminal, PC, or the like having a communication function and a camera function, and is used by a dealer (person in charge) who appraises the target product to be appraised.

[0030] (General configuration of information processing device) A typical information processing device 600 in which the server device 200 according to the present embodiment is realized will be described.

[0031] As shown in FIG. 2, the information processing device 600 includes a CPU (Central Processing Unit) 601, a ROM (Read Only Memory) 602, a RAM (Random Access Memory) 603, a NIC (Network Interface Card) 604, an image processing unit 605, an audio processing unit 606, an auxiliary memory unit 607, an interface 608, an operation unit 609, and a display unit 610.

[0032] A CPU 601 controls the overall operation of the information processing device 600, and is connected to each component to exchange control signals and data.

[0033] The ROM 602 stores an IPL (Initial Program Loader) that is executed immediately after power is turned on. When this IPL is executed, a program stored in the auxiliary memory unit 607 is read into the RAM 603 and the CPU 601 starts executing the program.

[0034] The RAM 603 is for temporarily storing data and programs, and holds programs and data read from the auxiliary storage unit 607, as well as other data necessary for communication.

[0035] The NIC 604 is used to connect the information processing device 600 to a computer communication network such as the Internet, and may be configured as a 10BASE-T / 100BASE-T standard used in constructing a LAN (Local Area Network), an analog modem for connecting to the Internet using a telephone line, an ISDN (Integrated Services Digital Network) modem, an ADSL (Asymmetric Digital Subscriber Line) modem, a cable modem for connecting to the Internet using a cable television line, or the like.

[0036] The image processing unit 605 processes image data read from the auxiliary storage unit 607 or the like using an image calculation processor (not shown) included in the CPU 601 or the image processing unit 605, and then records the processed image data in a frame memory (not shown) included in the image processing unit 605. The image information recorded in the frame memory is converted into a video signal at a predetermined synchronous timing, and is output to the display unit 610 via the interface 608 or the like. In other words, under the control of the CPU 601, the image processing unit 605 generates images required in the progress of processing performed by the information processing device 600, and causes the display unit 610 to display the images.

[0037] The audio processing unit 606 converts audio data read from the auxiliary storage unit 607 or the like into an audio signal, and outputs it to an external speaker via the interface 608. In other words, under the control of the CPU 601, the audio processing unit 606 generates audio to be generated during the progress of processing performed by the information processing device 600, and outputs the audio from the speaker.

[0038] The auxiliary storage unit 607 is a hard disk or the like, and stores various programs and various data necessary for controlling the operation of the entire information processing device 600. For example, the auxiliary storage unit 607 stores a program for realizing the server device 200 according to the present embodiment. Then, under the control of the CPU 601, the auxiliary storage unit 607 appropriately reads out the stored programs and data, and temporarily stores them in the RAM 603 or the like.

[0039] An operation unit 609 and a display unit 610 are connected to the interface 608. Note that the interface 608 may also transmit and receive necessary information to and from other connected external devices.

[0040] The operation unit 609 accepts operation inputs from an operator or the like who uses the information processing device 600 .

[0041] The display unit 610 renders an image according to the image data output by the image processing unit 605 , and displays it to an operator or the like who uses the information processing device 600 .

[0042] In addition, the information processing device 600 may include a drive unit such as a DVD (Digital Versatile Disc)-ROM instead of the auxiliary storage unit 607. In this case, the information processing device 600 reads out programs and data from a DVD-ROM or the like that is loaded into the drive unit, and operates in the same manner as described above.

[0043] (Embodiment 1) Hereinafter, the functional configuration of the server device 200 according to the first embodiment will be described with reference to Fig. 3 to Fig. 10. This server device 200 is realized by the above-mentioned information processing device 600. For example, when the information processing device 600 is powered on, a program that causes the information processing device 600 to function as the server device 200 is executed, and the server device 200 according to the first embodiment is realized. The seller terminal 300, the purchaser terminal 400, and the appraiser terminal 500 are also realized by an information processing device 600, but a description of this will be omitted and the following will describe the server device 200, which is the most characteristic feature of embodiment 1.

[0044] (Functional configuration of the server device according to the first embodiment) 3 is a block diagram showing an example of a functional configuration of the server device 200 according to embodiment 1. As shown in the figure, the server device 200 includes a receiving unit 210, a transmitting unit 220, a storage unit 230, and a control unit 240.

[0045] The receiving unit 210 receives various information sent from the seller terminal 300, the purchaser terminal 400, and the appraiser terminal 500. For example, the receiving unit 210 receives request information requesting product information and purchase request information requesting the purchase of a product from the purchaser terminal 400. Note that, when the product purchased at the purchaser terminal 400 (purchaser) is a target product to be appraised, the purchase request information requesting the purchase of the target product also includes information indicating whether or not to request appraisal from an appraiser. In addition, when the appraisal result of the appraiser for the target product indicates that it is impossible to appraise the product, the receiving unit 210 receives a response to the inquiry information from the purchaser terminal 400, which will be described later.

[0046] The above-mentioned NIC 604 or the like can function as such a receiving unit 210.

[0047] The transmission unit 220 is controlled by the control unit 240 and transmits necessary information to the seller terminal 300, the purchaser terminal 400, and the appraiser terminal 500. For example, when a product purchased at the purchaser terminal 400 is the target product to be appraised and an appraisal is requested from the purchaser terminal 400, the transmission unit 220 transmits a two-dimensional code to the seller terminal 300 as described below, and instructs the seller terminal 300 to deliver the target product to the appraiser. In addition, if the appraisal result of the appraiser regarding the target product is that it is impossible to appraise, inquiry information is sent to the purchaser terminal 400 to inquire whether to continue the transaction. In addition, when the response to the inquiry information is to continue the transaction, the transmission unit 220 transmits purchaser information, including the address and name of the purchaser, to the appraiser terminal 500 and instructs the appraiser terminal 500 to deliver the target product to the purchaser. On the other hand, when the response to the inquiry information is to cancel the transaction, the transmission unit 220 transmits seller information, including the address and name of the seller, to the appraiser terminal 500 and instructs the appraiser terminal 500 to deliver the target product to the seller.

[0048] The above-mentioned NIC 604 or the like can function as such a transmission unit 220.

[0049] The storage unit 230 stores various information necessary for commercial transactions between sellers and purchasers. For example, the storage unit 230 stores user management information 231 and product management information 232.

[0050] First, the user management information 231 is information for managing each user including a seller and a buyer. Specifically, as shown in FIG. 4, the user management information 231 includes a user ID 231a, a user name 231b, an address 231c, and an email address 231d.

[0051] In addition, the user management information 231 may also be configured to manage other information such as passwords, payment account numbers, credit card numbers, unique identification information of the terminal used (seller terminal 300 or purchaser terminal 400), evaluation points, and profiles.

[0052] Next, the product management information 232 is information for managing the put up product. Specifically, as shown in Fig. 5, the product management information 232 includes a product ID 232a, a seller ID 232b, a product name 232c, a price 232d, and an appraisal target 232e.

[0053] The seller ID 232b is the user ID of the user who put up the item for sale. Also, the appraisal target 232e is information indicating whether the put up item is subject to appraisal by an appraisal company, and "◯" in the figure indicates that the item is subject to appraisal.

[0054] In addition, the product management information 232 may also be configured to manage information such as images and videos about products and explanations about products.

[0055] In addition to this information, the storage unit 230 also stores information about the appraiser.

[0056] The above-mentioned auxiliary storage unit 607 or the like can function as such a storage unit 230.

[0057] 3, the control unit 240 controls the entire server device 200. The control unit 240 includes, for example, a transaction management unit 241, a two-dimensional code generation unit 242, a product information provision unit 243, an appraisal result acquisition unit 244, and an appraisal management unit 245.

[0058] The transaction management unit 241 manages commercial transactions between sellers and buyers. For example, in response to a request from the purchaser terminal 400, the transaction management unit 241 presents a product list screen SI as shown in Fig. 6 to the purchaser terminal 400. Then, when a product is selected from the product list screen SI, the transaction management unit 241 presents, for example, a product information screen SJ as shown in Fig. 7 to the purchaser terminal 400. On this product information screen SJ, an icon IC indicates that the product (handbag) is to be appraised. When a purchase button (proceed to purchase button) KB on the product information screen SJ is pressed by a purchaser using the purchaser terminal 400, the transaction management unit 241 presents a payment screen, etc., required for payment, to the purchaser terminal 400, and confirms the purchase by the purchaser. Note that if the product is a target product that is subject to appraisal, it is also determined, according to the operation from the purchaser terminal 400, whether to request an appraisal of the target product from an appraiser. Furthermore, the transaction management unit 241 may also be able to support price negotiations by enabling chat between the buyer and the seller, for example, before settlement.

[0059] In addition, when a commercial transaction between a seller and a buyer is conducted anonymously, the transaction management unit 241 presents a two-dimensional code (with the delivery destination being the buyer) generated by the two-dimensional code generation unit 242 described below to the seller terminal 300 and instructs the seller to deliver the target product to the buyer. Furthermore, when the product purchased at the purchaser terminal 400 is a target product to be appraised and an appraisal is requested from the purchaser terminal 400, the transaction management unit 241 presents the two-dimensional code (with the delivery destination being the appraiser) generated by the two-dimensional code generation unit 242 to the seller terminal 300 and instructs the seller terminal 300 to deliver the target product to the appraiser. For example, the transaction management unit 241 presents a delivery instruction screen HS as shown in Fig. 8 to the seller terminal 300 and instructs the seller terminal 300 to deliver the target product to the appraiser.

[0060] Returning to FIG. 3, the two-dimensional code generating unit 242 generates a two-dimensional code that can have information in both the vertical and horizontal directions. For example, the two-dimensional code generating unit 242 generates the two-dimensional code NC1 included in the delivery instruction screen HS shown in FIG. This two-dimensional code NC1 is, for example, a code obtained by encoding information including the address and name of the appraiser and information including the product ID of the target product. The two-dimensional code NC1 may be a link-type code other than directly encoding this information. For example, the two-dimensional code NC1 may be a code obtained by encoding a Uniform Resource Locator (URL) that stores information including the address and name of the appraiser and information including the product ID of the target product.

[0061] The product information providing unit 243 provides product information of the target product to the appraiser terminal 500 in response to a request from the appraiser terminal 500 which appraises the target product. For example, when the two-dimensional code NC1 included in the delivery instruction screen HS shown in Figure 8 described above is affixed to the packaging box of the target product by a delivery company or a delivery reception company and delivered to an appraiser, when the two-dimensional code NC1 is read using the camera function of the appraiser terminal 500, the appraiser terminal 500 accesses the server device 200. Therefore, in response to the two-dimensional code NC1 read by the appraiser terminal 500, the product information providing unit 243 reads product information about the target product from the storage unit 230 (product management information 232) and provides it to the appraiser terminal 500. That is, the agent using the appraising agent terminal 500 performs appraisal based on the delivered target product and the product information provided by the server device 200 (product information providing unit 243).

[0062] The appraisal result acquisition unit 244 acquires the appraisal result based on the target product and product information from the appraiser terminal 500. For example, the appraisal result acquisition unit 244 acquires from the appraisal agent terminal 500 an appraisal result indicating that the target product is genuine, an appraisal result indicating that the target product is a counterfeit or imitation, or an appraisal result indicating that the target product cannot be appraised. In addition, an appraisal result that the item cannot be authenticated may occur, for example, in the case of brand-name products or novelty goods, when products that are sold locally in a country other than Japan are brought into Japan through parallel imports or the like.

[0063] When the appraisal result acquired by the appraisal result acquisition unit 244 indicates that the appraisal cannot be authenticated, the appraisal management unit 245 controls the transmission unit 220 to transmit inquiry information inquiring whether or not to continue the transaction related to the target product to the purchaser terminal 400. In other words, the appraisal management unit 245 and the transmission unit 220 together constitute an inquiry information transmission unit. For example, the appraisal management unit 245 transmits an inquiry screen TA as shown in Fig. 9 to the purchaser terminal 400. In addition to information notifying the purchaser of the appraisal result (unappraisal possible), this inquiry screen TA includes a check box CB for selecting whether to continue the transaction or cancel the transaction, and a send button SB for sending a response.

[0064] Furthermore, the appraisal management unit 245 receives a response from the purchaser terminal 400 that sent the above-mentioned inquiry information (inquiry screen TA) via the receiving unit 210. That is, the appraisal management unit 245 and the receiving unit 210 together constitute a response information receiving unit. For example, when the purchaser checks the checkbox CB indicating that he / she wishes to continue the transaction on the inquiry screen TA shown in Figure 9 described above and presses the send button SB, the appraisal management unit 245 receives a response from the purchaser terminal 400 indicating that the commercial transaction related to the target product will be continued. On the other hand, if the purchaser checks the checkbox CB on the inquiry screen TA indicating that he / she wishes to cancel the transaction and presses the send button SB, the appraisal management unit 245 receives a response from the purchaser terminal 400 indicating that the commercial transaction related to the target product will not be continued.

[0065] Then, when the purchaser terminal 400 responds that the transaction should be continued, the appraisal management unit 245 concludes the transaction and instructs the appraiser terminal 500 to send the target product to the purchaser. For example, the appraisal management unit 245 presents a delivery instruction screen SG1 as shown in Fig. 10 to the appraiser terminal 500 and instructs the appraiser terminal 500 to send the target product to the purchaser. That is, the appraisal management unit 245 presents purchaser information, including the purchaser's address and name, on a delivery instruction screen SG1 shown in FIG. 10, and instructs the appraiser to deliver the target product to the purchaser. On the other hand, if the purchaser terminal 400 responds that the transaction will not be continued, the appraisal management unit 245 instructs the appraisal agent terminal 500 to cancel the transaction for the target product and to send the target product to the seller. That is, the appraisal management unit 245 presents seller information, including the seller's address and name, on another delivery instruction screen, and instructs the appraiser to deliver the target product to that seller.

[0066] In addition, when the appraisal result acquired by the appraisal result acquisition unit 244 indicates that the product is genuine, the appraisal management unit 245 instructs the appraisal company to present the purchaser information on another delivery command screen and deliver the target product to the purchaser without sending the above-mentioned inquiry information. Furthermore, even if the appraisal result acquired by the appraisal result acquisition unit 244 is that the item is a counterfeit or imitation, the appraisal management unit 245 does not send the above-mentioned inquiry information, but instead presents the seller information on another delivery instruction screen and instructs the appraiser to deliver the target item to the seller.

[0067] The above-mentioned CPU 601 and the like can function as the control unit 240 having such a configuration.

[0068] (Operation of the Server Device According to the First Embodiment) Hereinafter, the operation of the server device 200 according to the first embodiment having such a configuration will be described with reference to Fig. 11 and Fig. 12. Fig. 11 is a flowchart showing the flow of a sales process executed by the server device 200. Fig. 12 is a flowchart showing the flow of an appraisal management process executed by the server device 200.

[0069] First, the sales process will be described with reference to Fig. 11. This sales process is started in response to an access from the purchaser terminal 400, for example.

[0070] First, the server device 200 presents a product list screen to the purchaser terminal 400 (step S11). For example, the control unit 240 (transaction management unit 241) presents a product list screen SI as shown in FIG.

[0071] The server device 200 determines whether or not a product has been selected (step S12). For example, the control unit 240 (transaction management unit 241) determines whether any product has been selected on the product list screen SI shown in FIG.

[0072] If the server device 200 determines that no product has been selected (step S12; No), the process returns to step S11. Then, the server device 200 presents a product list screen of a different product in response to an operation from the purchaser terminal 400.

[0073] On the other hand, when it is determined that a product has been selected (step S12; Yes), the server device 200 determines whether or not the selected product is a target product to be authenticated (step S13). For example, the control unit 240 (transaction management unit 241) refers to the product management information 232 as shown in FIG. 5 described above for the selected product, and determines whether the appraisal target 232e is marked "◯".

[0074] When the server device 200 determines that the product is a target product (step S13; Yes), it presents a product information screen including an icon indicating that the product is a target product (step S14). For example, the control unit 240 (transaction management unit 241) presents, on the purchaser terminal 400, a product information screen SJ including an icon IC as shown in FIG.

[0075] On the other hand, if it is determined that the product is not a target product (step S13; No), the server device 200 presents a normal product information screen (step S15). That is, the control unit 240 presents, on the purchaser terminal 400, a product information screen that does not include an icon indicating that the product is a target product.

[0076] The server device 200 determines whether or not a purchase has been requested (step S16). For example, the control unit 240 (transaction management unit 241) determines whether the purchase button (the button to proceed to purchase) KB has been pressed by the purchaser using the purchaser terminal 400 on the product information screen SJ shown in FIG.

[0077] If the server device 200 determines that a purchase has not been requested (step S16; No), the server device 200 returns the process to the above-mentioned step S11.

[0078] On the other hand, if it is determined that a purchase has been requested (step S16; Yes), the server device 200 finalizes the purchase after necessary payment (step S17). For example, the control unit 240 (transaction management unit 241) presents a payment screen or the like required for payment to the purchaser terminal 400, and confirms the purchase of the product by the purchaser. If the product is a target product that is subject to appraisal, it is also determined whether or not to request an appraisal of the target product from an appraiser, according to an operation from the purchaser terminal 400.

[0079] Next, the appraisal management process will be described with reference to Fig. 12. This appraisal management process is started, for example, after a purchaser purchases a target product to be appraised in the sales process of Fig. 11 described above and the purchaser requests an appraisal of the target product from an appraiser. In this case, a delivery instruction screen HS as shown in Fig. 8 described above is presented on the seller terminal 300 that has put up the purchased target product, and the seller is instructed to deliver the target product to the appraiser.

[0080] First, the server device 200 determines whether or not there is access via a two-dimensional code (step S21). For example, when the two-dimensional code NC1 included in the delivery instruction screen HS shown in Figure 8 described above is affixed to the packaging box of the target product by a delivery company or a delivery reception company and delivered to an appraiser, when the two-dimensional code NC1 is read using the camera function of the appraiser terminal 500, the appraiser terminal 500 accesses the server device 200. When the server device 200 determines that there is no access via the two-dimensional code (step S21; No), it waits for an access.

[0081] On the other hand, if it is determined that there has been access via the two-dimensional code (step S21; Yes), the server device 200 provides the product information to the appraiser terminal 500 (step S22). That is, in response to the two-dimensional code read by the appraiser terminal 500, the control unit 240 (product information providing unit 243) reads product information about the target product from the memory unit 230 (product management information 232) and provides it to the appraiser terminal 500.

[0082] The server device 200 presents an input screen for the verification result (step S23). For example, in response to an operation from the appraiser terminal 500, the control unit 240 (appraisal result acquisition unit 244) presents an input screen on the appraiser terminal 500 for inputting the appraisal result.

[0083] The server device 200 determines whether or not the authentication result has been acquired (step S24). For example, the control unit 240 (the appraisal result acquisition unit 244) determines whether the appraisal result has been input on the input screen presented on the appraiser terminal 500.

[0084] If the server device 200 determines that the authentication result has not been acquired (step S24; No), the server device 200 returns the process to the above-mentioned step S23.

[0085] On the other hand, when it is determined that the authentication result has been acquired (step S24; Yes), the server device 200 determines whether or not the authentication result is unauthenticable (step S25).

[0086] When the server device 200 determines that the authentication result is unauthenticable (step S25; Yes), it transmits inquiry information to the purchaser terminal 400 inquiring whether or not to continue the commercial transaction related to the target product (step S26). For example, the control unit 240 (the appraisal management unit 245) controls the transmission unit 220 to transmit the inquiry screen TA as shown in Fig. 9 to the purchaser terminal 400. In addition to information notifying the appraisal result (unappraisal possible), this inquiry screen TA includes a check box CB for selecting whether to continue the transaction or cancel the transaction, and a send button SB for sending a response.

[0087] The server device 200 determines whether or not a response has been received from the purchaser terminal 400 (step S27). For example, the appraisal management unit 245 determines whether or not any check box CB has been checked and the send button SB has been pressed on the purchaser terminal 400 to which the inquiry screen TA shown in FIG. 9 has been sent.

[0088] If the server device 200 determines that there has been no response from the purchaser terminal 400 (step S27; No), it continues to wait for a response.

[0089] On the other hand, when it is determined that a response has been received from the purchaser terminal 400 (step S27; Yes), the server device 200 determines whether the response is to continue the transaction (step S28). For example, when the check box CB for continuing the transaction is checked and the send button SB is pressed on the inquiry screen TA shown in Fig. 9, the control unit 240 (the appraisal management unit 245) determines that the reply from the purchaser terminal 400 is to continue the transaction related to the target product. Also, when the check box CB for canceling the transaction is checked and the send button SB is pressed on the inquiry screen TA, the control unit 240 determines that the reply from the purchaser terminal 400 is to not continue the transaction related to the target product.

[0090] When the server device 200 determines that the reply is to continue the transaction (step S28; Yes), it concludes the transaction and issues a command to send the target product to the purchaser (step S29). For example, the control unit 240 (the appraisal management unit 245) presents the delivery instruction screen SG1 as shown in FIG. 10 on the appraiser terminal 500, and instructs the appraiser terminal 500 to send the target product to the purchaser.

[0091] On the other hand, if it is determined that the reply does not indicate that the transaction is to be continued (step S28; No), the server device 200 cancels the transaction and issues a command to send the target product to the seller (step S30).

[0092] Moreover, in the above-mentioned step S25, when it is determined that the determination result is not unauthenticable (step S25; No), the server device 200 determines whether or not the determination result is a genuine product (step S31).

[0093] If the server device 200 determines that the product is genuine (step S31; Yes), the server device 200 advances the process to step S29 described above. That is, the server device 200 issues a command to complete the transaction and to specify the delivery address of the target product as the purchaser.

[0094] On the other hand, if the determination result indicates that the product is not genuine (the determination result indicates that the product is a counterfeit or imitation) (step S31; No), the server device 200 advances the process to step S30 described above. That is, the server device 200 issues a command to cancel the transaction and to send the target product to the seller.

[0095] If the appraisal result is that the item cannot be appraised by this appraisal management process, inquiry information is sent to the purchaser terminal 400. Then, depending on the response to the inquiry information, it becomes possible to continue or cancel the transaction. For example, if a customer who purchases a brand-name product understands that even genuine products may become unauthenticated, the customer can reply to the inquiry information that he or she wishes to continue with the transaction, thereby making it possible to purchase the product even if it becomes unauthenticated.

[0096] As a result, even if the appraisal results of the appraiser are inappropriate, the transaction can be concluded with the purchaser's consent.

[0097] (Embodiment 2) In the above-mentioned embodiment 1, a case has been described in which information about the purchaser and seller is presented to the appraiser terminal 500 which appraises the target product, but it is also possible to deliver the appraised target product to the purchaser or seller without presenting the information about the purchaser or seller. The following describes a second embodiment in which the delivery address of the target product is kept secret from the appraiser.

[0098] (Functional configuration of the server device according to the second embodiment) The functional configuration of the server device 200 according to the second embodiment is similar to that shown in FIG. However, if the purchaser terminal 400 that sent the inquiry information responds that it wishes to continue the commercial transaction, the two-dimensional code generation unit 242 generates a new two-dimensional code that encodes the purchaser information, including the purchaser's address and name. Then, the appraisal management unit 245 presents the new two-dimensional code generated by the two-dimensional code generation unit 242 to the appraiser terminal 500, and issues a command for delivery using the two-dimensional code. For example, the appraisal management unit 245 presents a delivery command screen SG2 as shown in Fig. 13 to the appraiser terminal 500, and instructs the appraiser terminal 500 to specify the destination of the target product as the purchaser. In other words, the appraisal management unit 245 presents to the appraiser terminal 500 a delivery command screen SG2 including a two-dimensional code NC2 generated by the two-dimensional code generation unit 242 by encoding the purchaser information, and instructs the appraiser terminal 500 to specify the destination of the target product as the purchaser.

[0099] In addition, if the purchaser terminal 400 that sent the inquiry information responds that the commercial transaction will not be continued, the two-dimensional code generation unit 242 generates a new two-dimensional code that encodes the seller information, including the seller's address and name. Then, the appraisal management unit 245 presents the new two-dimensional code generated by the two-dimensional code generation unit 242 to the appraiser terminal 500, and issues a command for delivery using the two-dimensional code.

[0100] In addition, when the appraisal result acquired by the appraisal result acquisition unit 244 indicates that the product is genuine, the appraisal management unit 245 does not send any inquiry information, but instead presents a delivery instruction screen including a two-dimensional code generated by the two-dimensional code generation unit 242 by encoding the purchaser information to the appraiser terminal 500, and instructs the appraiser to deliver the target product. Furthermore, even if the appraisal result acquired by the appraisal result acquisition unit 244 is that the item is a counterfeit or imitation, the appraisal management unit 245 does not send any inquiry information, but instead presents a delivery instruction screen including a two-dimensional code generated by the two-dimensional code generation unit 242 by encoding the seller information to the appraiser terminal 500, and instructs the appraiser to deliver the item in question.

[0101] (Operation of the Server Device According to the Second Embodiment) Hereinafter, the operation of the server device 200 according to the second embodiment will be described with reference to Fig. 14. Fig. 14 is a flowchart showing the flow of the appraisal management process according to the second embodiment, which is executed by the server device 200. It is assumed that the server device 200 according to the second embodiment also executes the sales process shown in Fig. 11. In the sales process of Fig. 11, a target product to be appraised is purchased by a purchaser, and after the purchaser requests an appraiser to appraise the target product, the appraisal management process shown in Fig. 14 is started. The appraisal management process in Fig. 14 is obtained by adding step S41 and step S42 to the appraisal management process in Fig. 12. Therefore, in the following explanation, the processes that have the same content as the appraisal management process in Fig. 12 will be described briefly.

[0102] First, the server device 200 determines whether or not there is an access via a two-dimensional code (step S21), and if it determines that there is no access via a two-dimensional code (step S21; No), it waits for an access.

[0103] On the other hand, if it is determined that there has been access via the two-dimensional code (step S21; Yes), the server device 200 provides the product information to the appraiser terminal 500 (step S22) and displays an input screen for the appraisal result (step S23).

[0104] The server device 200 determines whether or not the authentication result has been acquired (step S24), and if it determines that the authentication result has not been acquired (step S24; No), returns the process to the above-mentioned step S23.

[0105] On the other hand, if it is determined that the appraisal result has been obtained (step S24; Yes), the server device 200 determines whether the appraisal result is unauthentic (step S25), and if it determines that the appraisal result is unauthentic (step S25; Yes), it sends inquiry information to the purchaser terminal 400 inquiring whether to continue the commercial transaction related to the target product (step S26).

[0106] The server device 200 determines whether or not a response has been received from the purchaser terminal 400 (step S27), and if it determines that no response has been received (step S27; No), it continues to wait for a response.

[0107] On the other hand, if it is determined that a response has been received from the purchaser terminal 400 (step S27; Yes), the server device 200 determines whether the response is to continue the transaction (step S28), and if it is determined that the response is to continue the transaction (step S28; Yes), it generates a two-dimensional code based on the purchaser's information (step S41). For example, the control unit 240 (the two-dimensional code generating unit 242) generates a new two-dimensional code by encoding purchaser information including the purchaser's address and name.

[0108] The server device 200 completes the transaction and issues a command to send the target product to the purchaser (step S29). For example, the control unit 240 (the appraisal management unit 245) presents the delivery instruction screen SG2 as shown in FIG. 13 on the appraiser terminal 500, and instructs the appraiser terminal 500 to send the target product to the purchaser. In other words, the control unit 240 presents the delivery instruction screen SG2, which includes the two-dimensional code NC2 generated by encoding the purchaser information, to the appraiser terminal 500, and instructs the appraiser terminal 500 to specify the purchaser as the delivery address for the target product.

[0109] On the other hand, if it is determined that the reply does not indicate that the transaction is to be continued (step S28; No), the server device 200 generates a two-dimensional code based on the seller's information (step S42). For example, the control unit 240 (two-dimensional code generation unit 242) generates a new two-dimensional code by encoding seller information including the seller's address and name.

[0110] The server device 200 instructs the user to cancel the transaction and to send the target product to the seller (step S30).

[0111] Furthermore, if it is determined in step S25 described above that the judgment result is not unauthentic (step S25; No), the server device 200 determines whether the judgment result is a genuine product or not (step S31), and if it determines that the judgment result is a genuine product (step S31; Yes), the process proceeds to step S41 described above.

[0112] On the other hand, if the determination result indicates that the product is not genuine (the determination result indicates that the product is a counterfeit or imitation) (step S31; No), the server device 200 advances the process to step S42 described above.

[0113] By the appraisal management process according to the second embodiment, it is possible to keep the information of the delivery destination of the target product (buyer information and seller information) secret from the appraiser. Also, in the appraisal management process according to the second embodiment, it is possible to continue or cancel the transaction depending on the purchaser's response to the inquiry information.

[0114] As a result, even if the appraisal results of the appraiser are inappropriate, the transaction can be concluded with the purchaser's consent.

[0115] (Modification of the second embodiment) In the appraisal management process of Figure 14 described above, a case has been described in which a two-dimensional code is generated in step S41 or step S42 after a response to the inquiry information is obtained from the purchaser terminal 400, but the two-dimensional code may be generated immediately without waiting for a response from the purchaser terminal 400. For example, in the authentication management process of FIG. 14, if it is determined in step S25 that the authentication is not possible (step S25; Yes), the control unit 240 (two-dimensional code generation unit 242) generates a link-type two-dimensional code to which information regarding the target product is linked. It is assumed that before the response information is acquired, information indicating that no response has been received from the purchaser is set at the link destination of the link-type two-dimensional code.

[0116] Then, in step S41, which is executed when it is determined that the response indicates that the transaction is to be continued (step S28; Yes), the control unit 240 (appraisal management unit 245) sets the purchaser information, including the purchaser's address and name, to the link destination of the linked two-dimensional code.

[0117] On the other hand, in step S42, which is executed when it is determined that the response is to not continue the transaction (step S28; No), the control unit 240 (appraisal management unit 245) sets seller information, including the seller's address and name, as the link destination of the link-type two-dimensional code.

[0118] In this case, the appraiser can immediately pack the appraised products, and then, for example, a delivery company that comes to collect and deliver the products can read the two-dimensional code and sequentially deliver the target products that are ready to be delivered to the purchaser or seller.

[0119] (Other embodiments) In the above variant of embodiment 2, a case has been described in which a new linked two-dimensional code is generated, but the two-dimensional code used for delivery from the seller to the appraiser may also be reused for delivery from the appraiser. For example, the two-dimensional code generating unit 242 generates NC1, which is used for delivery from the seller to the appraiser, as a link-type two-dimensional code. Then, as in the modified example of the above embodiment 2, when the appraisal management unit 245 receives a response from the purchaser terminal 400 indicating that the transaction should be continued, it sets the purchaser information, including the purchaser's address and name, at the link destination of the linked two-dimensional code. On the other hand, if a response is received from the purchaser terminal 400 indicating that the transaction will not be continued, the appraisal management unit 245 sets seller information, including the seller's address and name, as the link destination of the link-type two-dimensional code.

[0120] In the above first and second embodiments, the flea market system 100 has been described as an example, but the present invention is not limited to such a flea market service and can be applied to an auction system that provides an auction service, etc.

[0121] As described above, according to the present invention, it is possible to provide a server device, appraisal management method, and program that can complete a transaction with the purchaser's consent even if the appraisal result of the appraiser is inappropriate. [Explanation of symbols]
