Description

[Technical field]

[0001] The present invention relates to an information processing device and a program. [Background technology]

[0002] There have been technologies related to pricing (hereinafter referred to as "appraisal") of used cars for some time now (see, for example, Patent Document 1). However, as a practice, the party buying the used car (for example, a car dealer) is supposed to unilaterally perform the appraisal, which creates an unnatural situation where the party selling the used car (the car owner) has to request an appraisal from a party with a conflict of interest. In such situations, there is a great need to easily perform reasonable (fair) appraisals, and there are attempts to use AI (artificial intelligence) and mathematical models to appraise used cars. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-97679 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, to perform accurate appraisals using simple calculations using AI (artificial intelligence) or mathematical models, it is necessary to have a huge amount of car sales data as a prerequisite, but it is difficult to obtain such a large amount of sales data. Even if a huge amount of sales data were available, there are many car models that are not distributed in sufficient numbers on the market. In other words, for car models that are not distributed in sufficient numbers on the market, it is difficult to achieve a service level based on the assessment results obtained through statistical processing. Furthermore, the appraisal price calculated by statistical processing is merely an estimate based on past sales data, and it cannot necessarily be said to be a reasonable appraisal price.

[0005] The present invention has been made in view of the above circumstances, and has an object to provide a technique for assisting in the appraisal of things including vehicles. [Means for solving the problem]

[0006] In order to achieve the above object, an information processing device according to one aspect of the present invention comprises: An information processing device that supports evaluation of a predetermined object using a predetermined index, a first receiving means for receiving information including at least information necessary for the evaluation of the thing as first information when the information is presented by a requester who wishes to evaluate the thing; a first presentation means for presenting the first information to each of one or more evaluators who wish to perform the evaluation; a second receiving means for receiving the evaluations of the object by each of the one or more evaluators as second information when the evaluations are presented; evaluation means for performing the evaluation on the object based on the second information received by the second reception means; Equipped with.

[0007] A program according to one aspect of the present invention is a program corresponding to the information processing device according to the above aspect of the present invention. Effect of the Invention

[0008] According to the present invention, techniques can be provided to assist in the valuation of items, including vehicles. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0011] First, referring to FIG. 1, an overview of a service (hereinafter referred to as "this service") to which an information processing system (see FIG. 2 described later) including a server according to one embodiment of an information processing device of the present invention will be described.

[0012] FIG. 1 is a diagram showing an overview of the present service that can be realized by an information processing system including a server according to an embodiment of the information processing device of the present invention.

[0013] Figure 1 illustrates a service provider G, an assessee Ua, an assessor Ub, a server 1, an assessee terminal 2, an assessor terminal 3, a vehicle C, and a public blockchain B. This service is an example of a service provided by a service provider G that manages the server 1 to the assessee Ua and the assessor Ub. By using this service, the appraisee Ua can easily receive an appraisal of vehicle C. By using this service to appraise vehicle C, appraiser Ub can receive a specified incentive. Both the assessee Ua and the appraiser Ub are registered as "users" who use this service. Therefore, one user may use this service as the assessee Ua or as the appraiser Ub. However, from the standpoint of preventing fraud, a user who has requested an appraisal of vehicle C as the assessee Ua may not be allowed to make an appraisal as the appraiser Ub for the same case.

[0014] Each of the assessee Ua and the appraiser Ub can use this service using an assessee terminal 2 and an appraiser terminal 3, respectively, on which dedicated application software for users of this service (hereinafter referred to as the "dedicated app") is installed. In addition, each of the assessee Ua and the assessor Ub can also use this service from a dedicated website for users of this service (hereinafter referred to as the "dedicated site"), which is displayed by the browser function of each of the assessee terminal 2 and the assessor terminal 3. In the following, unless otherwise specified, when we say that "the assessee Ua operates the assessee terminal 2," it means one of the following: That is, it means that the assessee Ua launches a dedicated app installed on the assessee terminal 2 and performs various operations, or that the assessee Ua uses the Service from a dedicated site displayed by the browser function of the assessee terminal 2. In addition, when it is expressed that "the assessor Ub operates the assessor terminal 3," it means either that the assessor Ub launches a dedicated application installed in the assessor terminal 3 and performs various operations, or that the assessor Ub uses the Service from a dedicated website displayed by the browser function of the assessor terminal 3.

[0015] In this service, items including vehicles are appraised using the collective intelligence of multiple appraisers Ub, and the results of the appraisal are certified (notarized) using blockchain technology. This makes it easy to perform a reasonable appraisal of items including vehicles.

[0016] Specifically, the appraiser Ub operates the appraiser terminal 3 to perform user registration (step SS1) and waits for an appraisal request from the appraisee Ua. When performing user registration, the appraiser Ub also performs a Know Your Customer (KYC) procedure. This makes it possible to eliminate bots. It also makes it possible to prevent fraudulent activities such as creating multiple accounts to manipulate the appraisal price.

[0017] The assessee Ua, who has completed user registration, operates the assessee terminal 2 to complete user registration (step SS2), and performs an "listing" procedure to request an appraisal of vehicle C (step SS3). Specifically, the procedure for listing vehicle C involves creating an auction form, setting bidding conditions, paying the service fee, and recording the created auction form on the public blockchain B. This completes the "listing" procedure, and the assessee Ua only has to wait for the appraisal price to be presented by this service. Among the procedures for listing, "payment of service fee" refers to the procedure for paying the fee (i.e., service fee) that must be paid when the assessee Ua uses this service to request an appraisal of vehicle C. In this way, by collecting the service fee from the assessee Ua who lists the vehicle, it is possible to prevent situations such as a large number of vehicles C that have no commercial value being listed. In addition, the fee collected from the assessee Ua can be used to provide an incentive to the appraiser Ub.

[0018] In the process of listing, the following information is written or attached to the listing sheet created by the assessee Ua. That is, (1) information written on the vehicle inspection certificate (vehicle inspection certificate) (hereinafter referred to as "vehicle inspection certificate information"), (2) information on the manufacturer, model, and grade, (3) mileage, (4) information on the presence or absence of accidents or scratches, (5) the condition of the exterior and interior, (6) data on captured images of the vehicle C, and other information are written or attached to the listing sheet. Note that, in the process of listing, the information that the assessee Ua must provide may be all of the information (1) to (6) above, or some of the information may be optional. In addition, the assessee Ua may be able to select the information to be made public to the assessor Ub, and the information written on the listing sheet may be edited any number of times before it is recorded in the public blockchain B. In addition, the vehicle inspection certificate information may be acquired by reading a specific identifier (e.g., a QR code (registered trademark)). This reduces the time and effort required for the appraiser Ua to create an exhibition form. In addition, the data of the captured image of the vehicle C may be automatically edited. This makes it possible to automatically mask, for example, the license plate portion of the vehicle C from the captured image of the vehicle C.

[0019] The "bidding conditions" set by the appraisee Ua refer to the conditions under which the appraiser Ub performs his / her own appraisal and inputs (hereinafter referred to as "bid") a price (hereinafter referred to as "estimated price") that he / she considers to be appropriate as the appraisal price of the vehicle C. The bidding conditions include, for example, (1) the type of appraisal price, (2) the number of appraisers Ub, (3) the quality of the appraisers Ub, (4) the presence or absence of AI (artificial intelligence), (5) appraisal time, (6) the number of iterations, and (7) range. "(1) Type of valuation price" refers to setting which price is to be calculated as the valuation price, for example, an auction price for dealers only, dealer selling price, or retail price. "(2) Number of appraisers Ub" refers to setting the number of appraisers Ub participating in the bid. The more appraisers Ub there are, the more credible the valuation price will be, but the higher the fee required for the valuation will be. "(3) Quality of appraisers Ub" refers to setting the quality of appraisers Ub participating in the bid. Naturally, the higher the quality of appraisers Ub, the more credible the valuation price will be, but the higher the service fee required for the valuation will be. For example, the past winning rate of appraisers Ub and the qualifications held by appraisers Ub (for example, used car appraiser) can be used as a criterion for judging "quality." The meaning of "winning rate" will be explained later. "(4) Presence or absence of AI (artificial intelligence)" refers to setting whether or not to include an AI (artificial intelligence) as one of the appraisers Ub, which will be a pacemaker. "(5) Valuation time" refers to setting a limit on the time required to present the valuation price. For example, if the assessee Ua wants to know the valuation price immediately, he / she can pay an option fee and set it to "express," or if he / she does not need to hurry, he / she can set the valuation time to "normal." Also, if he / she is not in a hurry at all, he / she can set it to "reasonable" to receive a discount. "(6) Number of repetitions" refers to setting the calculation of the valuation price to be repeated multiple times. This allows the assessee Ua to know the trend of the valuation price. "(7) Range" refers to setting a certain range for the valuation price presented. This allows the assessee Ua to express his / her preference, such as wanting the valuation price to be presented between this amount and this amount, when listing the item. By allowing such bidding conditions to be set at the time of listing, the convenience of the assessee Ua who uses this service can be increased, and as a result, an increase in the number of users of this service can be expected.

[0020] When the “listing” procedure is completed, the auction form recorded in the public blockchain B during the “listing” procedure is presented to the appraiser Ub (step SS4). Specifically, a list of vehicles C for which the auction procedure has been completed and for which the appraiser Ub can participate in bidding (hereinafter referred to as the “list of vehicles to be put up for auction”) is displayed on the appraiser terminal 3.

[0021] The appraiser Ub operates the appraiser terminal 3 to select an item for which he / she wishes to participate in the bidding from the list of exhibited vehicles, and confirms the contents of the exhibit form and the various conditions set by the appraisee Ua. The appraiser Ub then performs his / her own appraisal and performs a procedure (hereinafter referred to as "bidding") to present a price (hereinafter referred to as "estimated price") that he / she considers to be a reasonable appraisal price for the vehicle C (step SS5).

[0022] Here, in order for the appraiser Ub to make a bid, it is possible to make it so that he / she must use "points" held by the appraiser Ub and circulatable among users of the service (the appraiser Ub and the appraisee Ua) as a bid participation fee. In this case, the appraiser Ub makes a bid by consuming a predetermined number of points as a bid participation fee in order to enjoy points as an incentive for the appraisal. If the estimated price of the appraiser Ub is the same as or close to the appraisal price determined as a result of the appraisal, a large number of points are given to the appraiser Ub as an incentive. On the other hand, if the estimated price and the appraisal price are significantly different, no points are given, and the points used as the bid participation fee are lost. In this way, the bid made by the appraiser Ub is accompanied by a certain amount of game-like (gambling-like) nature, which can increase retention (maintenance of existing customers). Furthermore, the appraiser Ub can be made to recognize that accurately predicting the appraisal price is the best way to earn a large number of points.

[0023] The list of vehicles on offer displayed on the appraiser terminal 3 can be set to display all items on offer, or it can be set to display only items for which the appraiser Ub operating the appraiser terminal 3 can participate in bidding. The appraiser Ub can set filtering conditions for the cases displayed in the list of exhibited vehicles. Specifically, for example, the appraiser Ub can display only the models that the appraiser Ub specializes in, or display only the cases that offer a predetermined amount of incentive or more. In addition, when the setting is such that all exhibited cases are displayed in the list of exhibited vehicles, it is also possible to display only the cases in which the appraiser Ub can participate.

[0024] In addition, this service can be set up so that when an item is listed that meets conditions set in advance by the appraiser Ub, the appraiser Ub is notified of this.

[0025] The appraiser terminal 3 also displays a UI (User Interface) for the appraiser Ub to make a bid. This UI displays information that is a digest of the information written on the auction form, information showing the current bidding status, etc. Specifically, for example, messages such as "X number of more bidders can participate in bidding" and "Bidding will end in X minutes", the current number of bidders, links to other items with similar bidding conditions, a reference valuation price based on AI (artificial intelligence), information showing the distribution and variance of predicted prices, etc. can be displayed. This can encourage more active bidding.

[0026] The server 1 waits for the input of the predicted price by the appraiser Ub within a predetermined time, closes the listing after the predetermined time has elapsed or when all the predicted prices have been input, and determines the assessed price of the vehicle C based on the multiple predicted prices (step SS6). Here, the server 1 performs the appraisal using the collective intelligence of the multiple appraisers Ub, but the specific method is not particularly limited. For example, the median of the distribution of the multiple predicted prices can be set as the appraised price. However, appraiser Ub cannot participate in the bidding for all vehicles C for which the listing procedure has been completed. As mentioned above, if the appraiser does not satisfy the "conditions for appraisal" set by the appraisee Ua, he / she cannot participate in the bidding. Specifically, for example, if the condition for the quality of appraiser Ub requires that he / she hold a certain qualification (e.g., used car appraiser), then only those who hold the specified qualification can participate in the bidding as appraiser Ub.

[0027] In addition, in this service, the number of items that an appraiser Ub can participate in depends on the status of the user registration procedure. Specifically, the number of items that an appraiser Ub can participate in depends on the progress of the individual identification of the appraiser Ub. Specifically, the "progress in personal identification" is determined by the following criteria, for example. That is, the "progress in personal identification" is determined by (1) whether SMS authentication has been completed, (2) whether presence authentication has been completed, and (3) whether a qualification certificate has been submitted. Among these, "SMS authentication" refers to a personal authentication method that utilizes SMS (Short Message Service). Also, "presence authentication" refers to a personal authentication method that uses data from an image (a so-called selfie) of the person and their identification document together to verify whether the person actually exists. Also, "qualification certificate" refers to proving that a person holds a qualification by presenting a document issued by an institution that grants a specified qualification (for example, used car appraiser) that certifies that the person holds the qualification. The more the individual is identified, the more personal and reliable the predicted price becomes. For this reason, the service provider G sets up the service so that the more the individual identity of the appraiser Ub becomes, the more items he or she can participate in bidding for. In addition, the more the individual identity of the appraiser Ub becomes, the greater the risk that the appraiser Ub bears as an individual. For this reason, the service provider G sets up the service so that, as one compensation, the more the incentive provided to the appraiser Ub becomes, the more the individual identity of the appraiser Ub becomes.

[0028] Each user of this service, such as the assessee Ua or the assessor Ub, has one blockchain address for one personal account. Therefore, the public blockchain B treats users of this service as users who can freely use one address.

[0029] The server 1 also notifies the assessee Ua that the assessed price of the vehicle C has been determined, and presents the assessed price (step SS7). Note that the specific method for presenting the assessed price to the assessee Ua is not particularly limited. For example, the server 1 may issue to the assessee terminal 2 a certificate (hereinafter referred to as a "price certificate") indicating that the assessed price of the vehicle C has been determined, and the assessed price.

[0030] FIG. 2 is a diagram showing a specific example of the structure of a price certificate issued by this service.

[0031] In addition to the assessed price, the price certificate may include, for example, the following information: (1) a QR code (registered trademark) Q1 indicating the URL (Uniform Resource Locator) of a web page where some or all of the information about the vehicle C that was the subject of the appraisal can be viewed, (2) a QR code (registered trademark) Q2 indicating the URL of a web page where some or all of the information about the appraiser Ub who participated in the bid can be viewed, and (3) information such as a digest of the contents of the exhibition form, a digest of the contents of the bidding conditions, and a digest of the contents of the bid, as text explaining the contents certified by the price certificate, may be included in the price certificate. This allows anyone who refers to the price certificate to identify the vehicle C that was the subject of the appraisal and to confirm whose appraisal determined the assessed price, thereby giving the price certificate public interest and authority.

[0032] Returning to FIG. 1, the server 1 provides incentives to the appraiser Ub who participated in the bid, according to the degree of involvement and contribution in determining the appraised price (step SS8). The content of the incentive provided to the appraiser Ub is not particularly limited. For example, the incentive may be "points" that can be circulated between users of this service (the appraiser Ub and the appraisee Ua), or cash or coupons. In addition, the incentive may be provided by assigning a higher score to an amount closer to the median in the distribution of multiple predicted prices, and a larger incentive may be provided to the appraiser Ub who predicted that amount.

[0033] A series of processes shown in steps SS1 to SS8 (hereinafter referred to as the "appraisal process") and various data used or generated in the appraisal process are recorded on the blockchain. Specifically, at least a part of the appraisal process is executed on the public blockchain B. Various data used or generated in the appraisal process include the auction form created by the appraiser Ua, the predicted price entered by the appraiser Ub, and the past winning rate of the appraiser Ub. Here, the "winning rate" is one of the indicators showing the high appraisal ability of the appraiser Ub. Specifically, when a score is used as an evaluation method for the predicted price, it means the ratio of the number of cases in which the appraiser Ub has the top score to the number of all cases in which the appraiser has participated. In other words, it means the ratio indicating the percentage of cases in which the appraiser's score was higher than the score of any other appraiser Ub out of the cases in which the appraiser participated.

[0034] In this way, by recording the appraisal process and various data used or generated in the appraisal process on the public blockchain B, the following is proven. That is, it is proven to the appraisee Ua that the appraisal process has been carried out correctly, etc. Also, it is proven to the appraiser Ub that the incentives have been distributed accurately, appropriately, and fairly, and if a score is assigned to the predicted price, the scoring has been proven on the public blockchain B, etc. As a result, the appraisal price calculated by this service will be an amount that clearly indicates that the relationship between the appraised vehicle C and the appraisal process is clear and complete, and that it has been notarized using blockchain technology. For this reason, the appraisal price calculated by this service is expected to be trusted not only by those who use this service, but also by the general public, and will be treated as an appraisal price that serves as the basis for information value.

[0035] In this service, a dedicated web page (hereinafter referred to as "My Page") that can be used individually by each user (appraisee Ua and appraiser Ub) is provided on a dedicated site. On My Page, information showing past listings and bidding records is displayed along with the listing slip at that time. For example, the listing slip displayed along with past bidding records can also display the number of points gained or lost by participating in a bid. In addition, on My Page, information that allows a user to review the details of each case, such as how past listings and bids were made, what position they were in at the time, and what the results were.

[0036] In addition, although not shown in the figure, a web page (hereinafter referred to as the "point history page") is provided as part of My Page or separate from My Page, which displays the history of points acquired or lost by each user (assessee Ua and assessor Ub). By viewing the point history page, users can at a glance grasp the total amount of points currently held and the history of their income and expenditure. In addition, the point history page is provided with link buttons that enable access to various websites where the points can be exchanged for various prizes, etc. This allows each user (assessee Ua and assessor Ub) to easily use the points they hold to exchange them for desired prizes, etc.

[0037] Next, with reference to FIG. 3, a description will be given of the configuration of an information processing system that realizes the provision of the above-mentioned service, that is, an information processing system including a server 1 according to an embodiment of an information processing device of the present invention. FIG. 3 is a diagram showing an example of the configuration of an information processing system including a server according to an embodiment of the information processing device of the present invention.

[0038] The information processing system shown in Figure 3 is configured to include a server 1, assessee terminals 2-1 to 2-n (n is an integer value greater than or equal to 1), assessor terminals 3-1 to 3-m (m is an integer value greater than or equal to 1), and a public blockchain B. The server 1, the assessee terminals 2-1 to 2-n, the assessor terminals 3-1 to 3-m, and the public blockchain B are each connected to each other via a predetermined network N such as the Internet.

[0039] The server 1 is an information processing device managed by the service provider G, and executes various processes to realize this service while communicating appropriately with the assessee terminals 2-1 to 2-n, the assessor terminals 3-1 to 3-m, and the public blockchain B.

[0040] Each of the assessee terminals 2-1 to 2-n is an information processing device operated by each of the assessees Ua1 to Uan, and is composed of, for example, a personal computer, a smartphone, a tablet, etc. Hereinafter, when there is no need to individually distinguish between the assessee terminals 2-1 to 2-n and the assessees Ua1 to Uan, they will be collectively referred to as the "assessee terminal 2" and the "assessee Ua", respectively.

[0041] Each of the assessor terminals 3-1 to 3-m is an information processing device operated by each of the assessors Ub1 to Ubm, and is composed of, for example, a personal computer, a smartphone, a tablet, etc. Hereinafter, when there is no need to distinguish between each of the assessor terminals 3-1 to 3-m and the assessors Ub1 to Ubm, they will be collectively referred to as the "assessor terminal 3" and the "assessor Ub," respectively.

[0042] Public blockchain B is one type of blockchain technology, and is a distributed network technology that has the function of preventing data tampering and destruction. Public blockchain B differs from private blockchains in that there is no central administrator, participation in the network is free, and participants are the ones who approve transactions. In public blockchain B, hash values, etc., whose generated values ​​are difficult to predict, are added to data blocks in units of transmission, and data tampering is made even more difficult by adding them in chronological order. In other words, existing blockchain technologies such as Ethereum, nem, and Libra can be applied to the public blockchain B. This can have the effect of making data tampering more difficult, for example.

[0043] FIG. 4 is a block diagram showing an example of a hardware configuration of a server in the information processing system shown in FIG.

[0044] The server 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, an input unit 16, an output unit 17, a memory unit 18, a communication unit 19, and a drive 20.

[0045] The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 18 into the RAM 13 . The RAM 13 also stores data and the like necessary for the CPU 11 to execute various processes.

[0046] The CPU 11, ROM 12, and RAM 13 are connected to one another via a bus 14. An input / output interface 15 is also connected to this bus 14. An input unit 16, an output unit 17, a storage unit 18, a communication unit 19, and a drive 20 are connected to the input / output interface 15.

[0047] The input unit 16 is configured with, for example, a keyboard and is used to input various information. The output unit 17 is configured with a display such as a liquid crystal display, a speaker, and the like, and outputs various information as images and sounds. The storage unit 18 is configured with a dynamic random access memory (DRAM) or the like, and stores various data. The communication unit 19 communicates with other devices (such as the assessee terminal 2, assessor terminal 3, and public blockchain B in Figure 3) via a network N including the Internet.

[0048] Removable media 30, such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory, is appropriately loaded into the drive 20. A program read from the removable media 30 by the drive 20 is installed in the storage unit 18 as necessary. Furthermore, the removable medium 30 can also store various data stored in the storage unit 18 in the same manner as the storage unit 18 .

[0049] Although not shown, the assessee terminal 2 and the assessor terminal 3 in Fig. 3 may have a configuration basically similar to the hardware configuration shown in Fig. 4. Therefore, a description of the hardware configuration of the assessee terminal 2 and the assessor terminal 3 will be omitted.

[0050] 4, various processes including the appraisal support process can be executed in the server 1. As a result, the service provider can provide the above-mentioned service to the site operator U and the appraisee Ua. "Assessment Support Processing" refers to the processing carried out to provide the Service described above. The following describes the functional configuration for executing the assessment support process executed in the server 1 according to this embodiment.

[0051] FIG. 5 is a functional block diagram showing an example of a functional configuration for executing an assessment support process, among the functional configurations of an information processing system including the server of FIG.

[0052] As shown in Figure 5, when the execution of the appraisal support process is controlled in the CPU 11 of the server 1, an item listing reception unit 101, a presentation unit 102, a bid reception unit 103, an evaluation unit 104, a recording control unit 105, and a point management unit 106 function. Furthermore, a user DB 181, a commodity DB 182, and a bid DB 183 are provided in one area of ​​the memory unit 18 of the server 1. The user DB 181 stores and manages information (hereinafter referred to as "user information") relating to users (appraisers Ua and appraisers Ub) who use this service. The user information includes, for example, the past listing history and bidding history of each user. The listing DB 182 stores and manages the listing forms and the like presented at the time of past listing for each item. The bid DB 183 stores and manages the predicted prices and the like presented at the time of past bidding for each item.

[0053] The bid acceptance unit 101 accepts a request for a price appraisal of vehicle C as a procedure for listing when an bid form required for the price appraisal of vehicle C and information including bidding conditions are presented and a prescribed fee is paid. That is, the bid acceptance unit 101 accepts the procedure for putting up auction for vehicle C when it is carried out at the assessee terminal 2, including creating an bid form, setting bidding conditions, and paying the service fee. The bid form that has been created and accepted by the bid acceptance unit 101 and information regarding the set bidding conditions are controlled to be recorded in the public blockchain B by the recording control unit 105, which will be described later.

[0054] The presentation unit 102 presents an exhibition form required for the price appraisal of vehicle C and information including bidding conditions to each of the appraisers Ub1 to Ubm who wish to appraise vehicle C based on its price. That is, the presentation unit 102 presents the auction form recorded in the public blockchain B during the auction procedure, together with a list of the auction vehicles, to each of the appraisers Ub1 to Ubm.

[0055] When a predicted price is presented as the appraisal of the price of vehicle C by each of the appraisers Ub1 to Ubm, the bid receiving unit 103 receives it. That is, when a bidding procedure in which a predicted price is input is carried out at the appraiser terminal 3, the bid receiving unit 103 receives this.

[0056] The evaluation unit 104 evaluates the price of the vehicle C based on the predicted prices as the price evaluations of the vehicle C by each of the appraisers Ub1 to Ubm, which are received by the bid receiving unit 103. Specifically, the evaluation unit 104 waits for the input of predicted prices by each of the appraisers Ub1 to Ubm within a predetermined time, closes the listing when the predetermined time has elapsed or when all predicted prices have been input, and determines the assessed price of vehicle C based on the input predicted prices. The evaluation unit 104 determines the assessed price of vehicle C based on, for example, the distribution of the predicted prices.

[0057] The recording control unit 105 controls the recording of the exhibition form, predicted prices, etc. in the public blockchain B, among the information including the exhibition form and bidding conditions required for the price appraisal of vehicle C received by the exhibition receiving unit 101, and the information regarding the predicted prices for the price appraisal of vehicle C by each of the appraisers Ub1 to Ubm received by the bid receiving unit 103.

[0058] The points management unit 106 manages points as a predetermined incentive provided to each of the appraisers Ub1 to Ubm based on the estimated price of the vehicle C by each of the appraisers Ub1 to Ubm.

[0059] Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within the scope that can achieve the object of the present invention are considered to be included in the present invention.

[0060] For example, in the above embodiment, the subject of the appraisal is a vehicle, but this is merely an example, and any object that can be the subject of the appraisal may be used. In other words, the subject of the appraisal may be not only an object but also a service.

[0061] For example, the structure of the price certificate shown in Figure 2 is merely one example. It is sufficient if the structure allows anyone who refers to the price certificate to identify the subject of the appraisal and to confirm whose appraisal determined the appraised price. It is even better if the structure allows the certificate to have public appeal and authority.

[0062] For example, in the above embodiment, a public blockchain is used, but the type of blockchain is not particularly limited and may be a private blockchain. It can be arbitrarily selected based on the actual use case, the required performance, or marketing. Also, at least a part of the processing performed on the blockchain in the above embodiment can be performed on the server 1 side.

[0063] Furthermore, the system configuration shown in FIG. 3 and the hardware configuration of the server 1 shown in FIG. 4 are merely examples for achieving the object of the present invention, and are not particularly limited.

[0064] In addition, the functional block diagram shown in Fig. 5 is merely an example and is not particularly limited. In other words, it is sufficient that the information processing system is provided with a function capable of executing the above-mentioned series of processes as a whole, and the type of functional block used to realize this function is not particularly limited to the example of Fig. 5.

[0065] Furthermore, the locations of the functional blocks are not limited to those shown in FIG. 5 and may be arbitrary. For example, in the example of Fig. 5, most of the above-mentioned assessment support processing is performed on the server 1 side, but this is not limited to the above. At least a part of the assessment support processing may be performed on the public blockchain B side, the assessee terminal 2 side, or the assessor terminal 3 side. That is, most of the functional blocks required to execute the appraisal support process are provided on the server 1 side, but this is merely an example. At least a part of the functional blocks arranged on the server 1 side may be provided on the public blockchain B side, the appraiser terminal 2 side, or the appraiser terminal 3 side.

[0066] Furthermore, the above-described series of processes can be executed by hardware or software. Furthermore, one functional block may be configured as a single piece of hardware, a single piece of software, or a combination of both.

[0067] When the series of processes is executed by software, the program constituting the software is installed into a computer or the like from a network or a recording medium. The computer may be a computer implemented with dedicated hardware. Furthermore, the computer may be a computer capable of executing various functions by installing various programs thereon, such as a server, a general-purpose smartphone, or a personal computer.

[0068] A recording medium containing such a program may be composed not only of a removable medium (not shown) that is distributed separately from the device body in order to provide the program to the user, but also of a recording medium that is provided to the user in a pre-installed state in the device body.

[0069] In this specification, the steps of describing a program to be recorded on a recording medium include not only processes that are performed chronologically according to the order, but also processes that are not necessarily performed chronologically but are executed in parallel or individually. In addition, in this specification, the term "system" refers to an overall device that is composed of a plurality of devices, a plurality of means, etc.

[0070] In summary, the information processing apparatus to which the present invention is applied is sufficient if it has the following configuration, and can take various different embodiments. That is, the information processing device to which the present invention is applied is In an information processing device that supports evaluation (e.g., appraisal) of a predetermined object (e.g., a vehicle C in FIG. 1) based on a predetermined index (e.g., price), A first reception means (e.g., the commodity reception unit 101 in FIG. 5) for receiving information including at least information necessary for the evaluation of the thing as first information when the information is presented by a requester (e.g., the assessee Ua in FIG. 1) who wishes to evaluate the thing; a first presentation means (e.g., the presentation unit 102 in FIG. 5) for presenting the first information to each of one or more evaluators (e.g., the evaluators Ub1 to Ubm in FIG. 1) who wish to perform the evaluation; a second reception means (e.g., the bid reception unit 103 in FIG. 5) for receiving, when the evaluation (e.g., the predicted price in FIG. 1) of the object by each of the one or more evaluators is presented, the evaluation as second information; an evaluation unit (e.g., the evaluation unit 104 in FIG. 5 ) that performs the evaluation on the object based on the second information received by the second reception unit; An information processing device comprising:

[0071] In this way, information required for the evaluation is received as a request for evaluation of an object using a predetermined index, and is presented to each of one or more evaluators who wish to perform the evaluation. Then, an evaluation of the object is performed based on the evaluations of the object by each of the one or more evaluators. As a result, a reasonable appraisal of the object, including a vehicle, can be easily performed.

[0072] In addition, the device may further include a recording control means (e.g., a recording control unit 105 in FIG. 5) that executes control to record at least a portion of the information (e.g., the auction form in FIG. 1 and the predicted price, etc.) contained in the first information received by the first receiving means and the second information received by the second receiving means in a blockchain (e.g., public blockchain B in FIG. 1).

[0073] This allows the information required for valuation and the valuations of items by one or more appraisers to be recorded on the blockchain, which then provides certification (notarization) using blockchain technology, making it easy to perform a valid valuation of items, including vehicles.

[0074] Moreover, the evaluation means includes: The evaluation may be based on a distribution of the results of the evaluation of the object by each of the one or more evaluators.

[0075] This makes it easy to assess things fairly, since the evaluation is based on the collective knowledge of multiple evaluators.

[0076] The system may further include an incentive management means (e.g., the point management unit 106 in FIG. 5) for managing predetermined incentives (e.g., points) provided to each of the one or more evaluators based on the result of the evaluation of the object by each of the one or more evaluators.

[0077] This can increase the motivation of the evaluator to perform a highly accurate evaluation. Also, it is possible to require the evaluator to use at least a part of the provided incentive in order to perform an evaluation. As a result, the evaluator will try to receive more incentive than the incentive he or she has used, which can increase retention (maintenance of existing customers).

[0078] Furthermore, the first reception means can receive the first information, and further receive a request from the client for the evaluation of the object when a predetermined fee has been paid by the client.

[0079] In this way, when the first information is received and the requester pays a predetermined fee, the requester's request for an evaluation of an object is officially accepted. As a result, it is possible to prevent a situation in which a large number of requests for evaluation of objects that have no commercial value are made. In addition, it is possible to provide a predetermined incentive to the evaluator using the fee paid by the requester. [Explanation of symbols]
