Then, the appraisal user control unit 56 of the appraisal user terminal 5 controls the appraisal user display unit 54 to display the product information of the sneakers to be traded and the genuine product information.

In this embodiment, a plurality of appraisal users appraise sneakers to be traded. For example, as shown in FIG. 8, the appraisal user display unit 54 of the appraisal user terminal 5 of each of the appraisal users U1 and U2 displays article information B of sneakers to be traded and authentic article information (not shown). be. The appraisal by these multiple appraisal users makes it clear who has appraised the sneakers to be traded, so the transparency of the appraisal is ensured. Thereby, appraisal of sneakers is performed appropriately.

In addition, the burden on the administrator who manages the server 4 can be reduced by appraisal by a plurality of appraisal users. Furthermore, since the blockchain, which will be described later, stores the score information of exhibiting users, appraisal users, and purchasing users, it is possible to obtain more appropriate appraisal results by weighting the appraisal results based on the score information. can.

In step S110, for example, article information B as shown in FIG. 9 is displayed on the exhibitor user display section .

As shown in FIG. 9, the appraisal user display unit 54 of a plurality of appraisal user terminals 5 displays a screen K1 regarding whether or not to appraise sneakers to be traded. When the appraisal user presses the "appraise" button on the screen K1, the article information B of the sneakers to be traded is displayed on the screen of the exhibiting user display section 34. FIG. The appraisal user determines whether or not the sneakers are genuine based on the article information B of the sneakers to be traded displayed on the appraisal user display unit 54 and the genuine article information (not shown) of the sneakers to be traded. Appraise. The item information B1 and B2 are examples of image information of sneakers, and the item information B3 is an example of purchase record information of sneakers.

9 is displayed on the appraisal user display section 54, the appraisal user presses the "genuine" or "fake" button on the screen K2 of FIG. 9 based on the final judgment. As a result, the appraisal information indicating the appraisal result of the sneakers corresponding to the article information displayed on the appraisal user display unit 54 is input to the appraisal user terminal 5 .

When the appraisal user inputs appraisal information indicating whether the sneakers to be traded are "genuine" or "fake" to the appraisal user operation unit 50 of the appraisal user terminal 5, in step S112, the appraisal user terminal 5 acquires the appraisal information.

In step S<b>114 , the appraisal user control unit 56 of the appraisal user terminal 5 transmits the appraisal information acquired in step S<b>112 to the server 4 .

In step S115, the server communication unit 42 of the server 4 receives the appraisal information transmitted from the plurality of appraisal user terminals 5 in step S114. Then, the server control unit 40 of the server 4 acquires a plurality of appraisal information acquired by the server communication unit 42 .

In step S116, the server control unit 40 of the server 4 generates under-examination information indicating that the sneaker to be traded is under final examination, and communicates with the server so as to transmit the under-examination information to the exhibit user terminal 3. control unit 42; The server communication unit 42 transmits the under-examination information to the exhibition user terminal 3 under the control of the server control unit 40 .

At step S118, the exhibit user communication unit 38 of the exhibit user terminal 3 receives the under-examination information transmitted from the server 4 at step S116. Then, the exhibit user control unit 36 of the exhibit user terminal 3 controls the exhibit user display unit 34 to display the under-examination information. At step S118, for example, the under-examination information S2 as shown in FIG.

In step S120, the server control unit 40 of the server 4 controls the server communication unit 42 to retrieve the timestamp, hash value, and transaction information stored in each block from the blockchain information storage unit 64 of the shared server 6. Get blockchain information including:

As shown in FIG. 4, the transaction information in the block chain information stores exhibit user information, purchase user information, appraisal user information, and distribution information in past transactions. Therefore, the server control unit 40 of the server 4, based on the exhibition user information, the purchase user information, the appraisal user information, the distribution information, and the plurality of appraisal information acquired in the above step S115, selects the sneakers to be traded. to determine the authenticity of

In step S122, the server control unit 40 of the server 4 selects the sneakers to be traded based on the plurality of appraisal information acquired in step S115 and the transaction information among the blockchain information acquired in step S120. to determine the authenticity of

For example, the server control unit 40 of the server 4 combines the plurality of pieces of appraisal information acquired in step S115 with the score information among the exhibit user information, appraisal user information, and purchase user information acquired in step S120. Based on this, a plurality of pieces of appraisal information are weighted according to the score information. Then, the server control unit 40 of the server 4 determines the authenticity of the sneakers based on the weighted pieces of appraisal information.

For example, the server control unit 40 of the server 4 acquires score information of a plurality of appraisal users from blockchain information. The score information of the appraisal user reflects, for example, information regarding the accuracy rate of the appraisals up to the previous time. Therefore, the server control unit 40 of the server 4 weights the appraisal information by the plurality of appraisal users according to the score information of the plurality of appraisal users, and based on the plurality of weighted appraisal information, determines the sneakers. Determine authenticity.

Specifically, the server control unit 40 weights one vote representing the appraisal information of the appraisal user according to the score information of the appraisal user. For example, if the score information of an appraisal user is "0.5", one vote of the appraisal user is multiplied by "0.5" and counted as 0.5 votes. Then, the server control unit 40 determines the authenticity of the sneakers based on the weighted appraisal information of the plurality of appraisal users. For example, the server control unit 40 determines that the sneakers are genuine when the weighted voting result is "55.5" for the genuine article and "10.5" for the fake article.

Also, for example, the server control unit 40 of the server 4 acquires the score information of the exhibiting user from the blockchain information. The score information of the exhibiting user reflects, for example, information regarding the rate at which authentic sneakers have been exhibited, information regarding the number of times genuine sneakers have been exhibited, and the like. Therefore, the server control unit 40 of the server 4 weights a plurality of pieces of appraisal information according to the scores of the exhibiting users, and determines the authenticity of the sneakers based on the weighted appraisal information. For example, if the user who exhibited this time has a low percentage of genuine sneakers exhibited in the previous exhibitions and the score is low, the final appraisal result will be weighted so that the probability that the final appraisal result will be "fake" is high. is done.

Also, for example, the server control unit 40 of the server 4 acquires the purchase user's score information from the blockchain information. The purchasing user's score information reflects, for example, information regarding whether or not payment was successfully made for a successful bid. Therefore, the server control unit 40 of the server 4 weights the pieces of appraisal information according to the purchase user's score information, and determines the authenticity of the sneakers based on the weighted appraisal information. For example, if the user who put up the item this time is the user who made the purchase in the previous exhibition, and there is a problem with the payment for the successful bid, and the score information is low, the final appraisal result will likely be a "fake". is weighted.

In step S<b>124 , the server control unit 40 of the server 4 controls the server communication unit 42 so as to transmit to the exhibition user terminal 3 the sneaker authenticity determination result obtained in step S<b>122 . The server communication unit 42 transmits the determination result of the authenticity of the sneakers to be traded to the exhibition user terminal 3 .

In step S126, the exhibit user communication unit 38 of the exhibit user terminal 3 receives the determination result regarding the authenticity of the sneakers to be traded, which was transmitted from the server 4 in step S124. Then, the exhibit user control section 36 of the exhibit user terminal 3 controls the exhibit user display section 34 to display the determination result.

For example, as shown in S3 and S4 of FIG. 7, the result of the judgment regarding the authenticity of the sneakers to be traded is displayed on the exhibitor user display section 34. FIG. S3 is a display screen when it is confirmed that the sneakers to be traded are genuine. Moreover, S4 is a display screen when it cannot be confirmed that the sneakers to be traded are genuine.

When the display screen of S3 is displayed on the exhibit user display section 34, the exhibit user presses the "withdrawal procedure" button T1 or presses the "hold as points" button T2. As a result, when the sneakers to be exhibited have been delivered to the purchasing user, the price of the sneakers to be traded (or points corresponding to the price) is transferred to the account of the exhibiting user.

On the other hand, when the display screen of S4 is displayed on the exhibiting user display section 34, the exhibiting user presses the "end" button T3 or presses the "donate" button T4. When the exhibiting user presses the "Donate" button T4, the trading target sneakers will be donated to the administrator of the authenticity determination system 1. FIG.

When the processing from step S100 to step S126 is completed, one transaction is completed. Therefore, in step S<b>128 , the server control unit 40 of the server 4 adds a new block to the blockchain stored in the blockchain information storage unit 64 of the shared server 6 via the server communication unit 42 .

The server control unit 40 of the server 4 adds a new block to the block chain using the exhibition user information, the purchase user information, the appraisal user information, and the distribution information in the current sneaker transaction as transaction information for a new block. . Also, the server control unit 40 of the server 4 stores the hash value and time stamp generated from the previous block in the new block.

In step S<b>130 , the shared server communication unit 62 of the shared server 6 receives information regarding the new block through communication processing with the server communication unit 42 of the server 4 . Then, the shared server control unit 60 of the shared server 6 adds a new block to the blockchain stored in the blockchain information storage unit 64 according to the information regarding the new block.

In this way, by storing the exhibition user information, the purchase user information, the appraisal user information, and the distribution information in the transaction of sneakers in the blockchain, falsification of these information becomes substantially impossible. Therefore, the reliability of the information stored in the blockchain is increased, and the transaction of sneakers is performed smoothly using such information.

Note that the blockchain stored in the blockchain information storage unit 64 of the shared server 6 can also be browsed from a terminal different from the server 4 . For example, the blockchain stored in the blockchain information storage unit 64 of the shared server 6 can be browsed from any of the purchasing user terminal 2, the exhibiting user terminal 3, and the appraisal user terminal 5. Therefore, in the community where sneakers are traded, it is possible to view the score information of each user. For example, information such as how reliable each user is can be visualized, so sneaker trading can be carried out smoothly.

In addition, by disclosing the score information of each user, the behavior of each user in trading sneakers is optimized. For example, when an exhibiting user puts up many counterfeit sneakers, the user's score decreases, so that the occurrence of a situation in which counterfeit sneakers are on the market is suppressed. Also, if the appraisal user makes a mistake in appraisal, the appraisal user's score is lowered, so appropriate appraisal is performed. In addition, since the user's score decreases due to the delay in listing or the delay in payment, sneaker transactions between users can be carried out smoothly.

As described above, the server of the authenticity determination system according to the present embodiment transmits article information representing sneakers to be traded to a plurality of appraisal user terminals. Then, each of the plurality of appraisal user terminals receives the item information transmitted from the server, controls to display the item information on the appraisal user display unit, and displays the appraisal result of the sneakers corresponding to the item information. Get appraisal information. Then, each of the plurality of appraisal user terminals transmits the acquired appraisal information to the server. Then, the server determines the authenticity of the sneakers based on the appraisal information transmitted from each of the plurality of appraisal user terminals. As a result, it is possible to appropriately determine the authenticity of the exhibited sneakers.

The present invention is not limited to the above-described embodiments, and various modifications and applications are possible without departing from the gist of the present invention.

For example, in the present embodiment, a case where sneakers are traded as an example of an article has been described as an example, but the present invention is not limited to this, and other articles different from sneakers may be targeted.

In addition, in the present embodiment, an example of weighting appraisal information using distribution information, exhibit user information, appraisal user information, and purchase user information has been described, but the present invention is not limited to this. It may be used as

Further, in the present embodiment, the case where the appraisal information by a plurality of appraisal users is weighted based on the appraisal information by a plurality of appraisal users and the blockchain information to obtain the final appraisal result has been described as an example. , but not limited to. For example, the authenticity of sneakers to be traded may be determined based on a majority vote of appraisal information by a plurality of appraisal users. In addition, when the information indicating that the sneaker is genuine is a predetermined percentage or more (for example, 95% or more) of each of the appraisal information by a plurality of appraisal users, the sneaker is determined to be genuine. You may make it

In addition, the blockchain used in the present embodiment includes various types of information, and these information may be used to properly conduct transactions of sneakers.

For example, if the sneakers to be traded are counterfeit (for example, if the information indicating that the sneakers are genuine is less than 95%), the appraisal results will be written in the distribution information of the blockchain, and the sneakers A label may be stored on the blockchain representing the prohibition of distribution of This will prevent counterfeit sneakers from circulating and make the sneaker trade more appropriate.

Also, for example, based on the score information of each user in the blockchain, users with high scores may be given preferential treatment and users with low scores may be treated coldly. For example, a user whose score is lower than a predetermined threshold may be restricted so as not to be able to use the transaction service provided by the authenticity determination system 1 . Also, for example, points may be given to the user according to the score. Alternatively, for example, a user with a high score may be allowed to apply for a commission discount or a plan developed on the transaction service. This optimizes the behavior of each user.

In addition, for example, the sneakers to be traded are given an RFID (Radio frequency identifier), which is an identification element for identifying the sneakers, and the product ID for identifying the sneakers can be read from the RFID. may In this case, the article ID is read by a predetermined reading device (not shown), and the article ID of the sneakers to be traded is stored in the blockchain distribution information. As a result, the sneaker is linked to the distribution information stored in the blockchain, and the distribution information becomes the sneaker's digital identity.

This also allows the blockchain distribution information to contain information about the exchange between ownership and value of the sneakers, and information about who has transferred the sneakers to whom. This ensures that the origin of the sneakers is clear and that the sneakers are traded properly.

In addition, in the present embodiment, the case where the appraisal is performed by a plurality of appraisal users has been described as an example, but the present invention is not limited to this, and the appraisal by the administrator who manages the server 4 is also taken into consideration. good too. In addition, from the image of the sneakers to be traded, the trained model for determining whether or not the sneakers are genuine is used to generate appraisal information, and the appraisal information generated by the trained model is also taken into consideration. You may do so.

Further, in the present embodiment, the case where the product information is generated by taking an image of the sneakers to be traded by the exhibiting user has been described as an example, but the present invention is not limited to this. For example, the exhibiting user may send sneakers to an administrator who manages the server 4 , and the administrator who manages the server 4 may generate product information of the sneakers to be traded. Then, the server 4 may transmit article information representing sneakers to be traded to a plurality of appraisal user terminals 5 .

Also, in the present embodiment, the case where the blockchain is stored in the blockchain information storage unit 64 of the shared server 6 has been described as an example, but the present invention is not limited to this, and where the blockchain is stored. good too. For example, it may be stored as a distributed ledger in storage units (not shown) of a plurality of appraisal user terminals 5 . Also, for example, there may be a plurality of shared servers 6, and each block chain information storage unit 64 may store the information as a distributed ledger. In this case, mining processing may be performed when a new block is added to the blockchain, and a corresponding reward may be given to the shared server, appraisal user terminal, or the like. As a mining method, for example, a mining method that employs a consensus algorithm such as Proof of Work (PoW) and Proof of Stake (PoS) can be used. Further, as a reward obtained as a result of mining, points that can be used in a sneaker trading service provided by the authenticity determination system 1 of the present embodiment can be used as a reward.

Further, in the specification of the present application, an embodiment in which the program is pre-installed has been described, but it is also possible to store the program in a computer-readable recording medium and provide it.
