Abstract

To enable proper management of ownership of an article in a real world.SOLUTION: An ownership management system 1 stores on a block chain an article ID which is unique information for identifying an article and an owner ID which is information indicating an owner of the article in association with each other, and generates a two-dimensional code from a hash value acquired from the block chain at the time of registration, the article ID, and the owner ID. The ownership management system 1 receives the two-dimensional code, extracts the hash value, the article ID, and the owner ID from the received two-dimensional code, acquires the article ID and the owner ID recorded on the block chain using the extracted hash value, determines a consistency relationship between the article ID and the owner ID extracted from the two-dimensional code, and outputs the extracted article ID and the owner ID when it is determined that the IDs have a consistency relationship.SELECTED DRAWING: Figure 1

Description

There is an application for application of Article 30, Paragraph 2 of the Patent Law Between September 22, 1991 and September 30, 1991, the website address of JAPAN MADE Secretariat Co., Ltd. https://www. aos webinar. com/@nft at a webinar titled “NFT & Digital Assets AOS 2021 September-A New World Created by Blockchain and NFT-”.

The present invention relates to an article ownership management system and an identification code for ownership management.

Digital data such as digital art works and digital items acquired in digital games are called digital assets, which themselves have economic value and are subject to trading transactions. However, since digital data can be easily duplicated, there is a problem in that duplicates are easily distributed, and illegal transfers by pretending to be the owner are easily carried out. In order to deal with this problem, a method of managing digital assets by non-fungible tokens (NFT) is being implemented.

NFT has uniqueness, unlike a fungible token (FT) that circulates as a currency that can be exchanged. By uploading analog or digital data such as texts, images, videos, music, etc. on the blockchain, an NFT corresponding to the uploaded data is issued. Each NFT is associated with a unique digital asset.

For example, Patent Literature 1 describes a system for providing digital assets protected by encryption. When shoes are purchased in the real world, the purchaser's owner unique ID code is associated with the digital shoe unique ID code corresponding to the proof of transaction. The associated owner unique ID code and digital shoe unique ID code are sent to a blockchain distributed ledger to record the transfer of the encrypted digital asset. After that, the transfer of ownership of encrypted digital assets will be recorded on the blockchain as a combination of the owner's unique ID code and the digital shoes' unique ID code. It is believed that the behavior can be prevented.

International Publication No. WO2020/118297

The method disclosed in Patent Document 1 is considered to be useful in managing the ownership of digital assets such as digital shoes. Since there is no particular mention of proper management, there is a need for measures to appropriately prevent fraudulent acts such as falsification of property rights of real-world goods and impersonation of owners.

SUMMARY OF THE INVENTION The present invention has been made to solve the above and other problems. One purpose is to provide the code.

In order to solve the above and other problems, an article ownership management system according to an aspect of the present invention provides article identification information, which is unique information for identifying an article, and the owner of the article.

[Configuration of management server 100]
Next, the configuration of the management server 100 that executes main data processing in the ownership management system 1 of this embodiment will be described. As illustrated in FIG. 1, in this embodiment, it is assumed that the management server 100 is composed of the processing server 110 and the service server 120 . In the following description, it is assumed that the main functions of the management server 100 related to ownership management are implemented in the processing server 110 .
FIG. 3 is a block diagram showing an example of hardware configuration and an example of functional implementation of the processing server 110 constituting the management server 100. As shown in FIG. The processing server 110 includes a processor 111 including a CPU, etc., a memory 112 including storage devices such as ROM, RAM, and flash memory, and storage devices such as semiconductor drives (SSD) and hard disk drives (HDD). Auxiliary storage unit 113, mobile wireless communication module, wireless LAN module such as Wi-Fi, communication unit 114 consisting of hardware providing communication functions such as network interface card (NIC), keyboard, touch panel, pointing device, microphone, etc. input devices and output devices such as various displays and speakers, and a data input/output (data IO) unit 116 for managing data input/output of each unit. In the configuration example of FIG. 1, the management server 100 is provided with the processing server 110 and the service server 120, but it may be configured as a single computer having the functions of both, or may be distributed and implemented on a network. can also As described above, the main data processing functions of the management server 100 are assumed to be performed by the processing server 110 in the following description for convenience.

In the memory 112, a property information processing unit 1121 that executes data processing for property right management in the property right management system 1 of this embodiment, a manufacturer of an article to be property right managed, A moving image processing unit 1122 that performs data processing related to moving image data and an authenticity determination processing unit 1123 that performs data processing related to authenticity determination processing provided by the property right management system 1 are stored. Each of these units is a program executed by processor 111 to perform respective data processing. An example of data processing by each program will be described later.

Auxiliary storage unit 113 is provided with ownership information storage unit 1131 . The ownership information storage unit 1131 stores ownership information about articles whose ownership is managed in the system 1 . This ownership information includes, for example, an item ID assigned to an item whose ownership is to be managed, an owner ID related to the owner of the item specified by the item ID, and the item ID and the owner ID. A record consisting of a combination of blockchain hash values issued when recording on the blockchain.

Next, data processing executed by the management server 100 in the ownership management system 1 of this embodiment will be described.
[Ownership management start processing]
First, data processing at the time of accepting property right management from the manufacturer, creator, etc. of the article using this system 1 will be described. FIG. 4 shows a flowchart illustrating the ownership management acceptance process.

When using the property right management service of the system 1, the user uses the terminal device 300 to request the management server 100 to issue an NFT associated with the target article and use the property right management service. At the time of request, text data indicating the article ID, which is a unique code attached to the article to be managed at the time of production and production, and the owner ID of the article manufacturer who is the owner of the article that was originally manufactured, and a video related to the article data to the management server 100 using the terminal device 300 .

This video data is a story that is introduced like a story by interweaving secret stories at the time of production and production when conveying the thoughts and concepts put into the goods by the producers and creators of the goods subject to property rights management. This is a video shot and created using the Telling method. As will be described later, it is also possible to use the property right management service without attaching moving image data.

The management server 100 can receive various types of information including article IDs from the terminal device 300 of the user. In step S400, the ownership information processing unit 1121 receives the article ID and the user's owner ID from the terminal device 300 of the user.

In step S410, the moving image processing unit 1122 determines whether the various information received from the terminal device 300 includes moving image data. If it is determined that moving image data is included (YES in step S410), in step S430 the moving image processing unit 1122 extracts this moving image data, and extracts the moving image data from a group of computers forming a distributed file system (IPFS network in this embodiment). 410 (see FIG. 1)) for storage (video data recording means).

In step S440, the moving image processing unit 1122 temporarily retains the hash value returned from the distributed file system (hereinafter referred to as the "distributed hash value"), and includes the distributed hash value, article ID, and owner ID. Together with the text data, it is uploaded onto the block chain (computer group 420 (see FIG. 1) that constitutes the network of the block chain).

If it is determined in step S410 that the video data is not included (NO in step S410), in step S420, the video processing unit 1122 uploads text data including the article ID and the owner ID to the blockchain for recording. Do (recording means). In steps S420 and S440, the item ID may be encrypted data.

In step S<b>450 , the ownership information processing unit 1121 of the management server 100 stores the blockchain hash value returned from the blockchain, the article ID, and the owner ID in the ownership information storage unit 1131 . The ownership information processing unit 1121 also associates and encodes the blockchain hash value, the article ID, and the owner ID, and generates a two-dimensional code as an identification code for ownership management (generating means). The generated two-dimensional code is transmitted to the user's terminal device 300 via the network N as electronic data such as a PDF file. Alternatively, the generated two-dimensional code may be printed at a print shop (not detailed here) and sent to the user.
As described above, for an item manufactured by a manufacturer, the item ID, which is an identification code unique to the item, and the owner ID, which is unique identification information indicating the owner of the item, are associated and recorded in the blockchain. . In this embodiment, an identification code for ownership management generated by encoding the blockchain hash value returned from the blockchain, the article ID, and the owner ID is positioned as the NFT.

[Owner change processing]
Next, the owner change processing by the ownership management system 1 of this embodiment will be described. FIG. 5 is a flowchart illustrating data processing in the owner change process. Ownership change processing is data processing for recording the ownership transfer on the system 1 when the ownership of an article subject to ownership management is transferred to another person due to the sale of the article or the like. Now, let us assume a case where the ownership is transferred from the goods producer or creator who has the ownership of the goods to the purchaser of the goods.

In step S<b>500 , the management server 100 receives an owner change request sent from the terminal device 300 by the article owner. The owner change request includes the purchaser's owner ID. As for the owner ID of the purchaser, if the purchaser already has the owner ID issued by the owner management system 1, the owner ID is obtained and used. If the purchaser does not have an owner ID, it can be configured so that the management server 100 that receives the owner change request issues a new one.

In step S<b>510 , the ownership information processing unit 1121 of the management server 100 records text data including the received article ID and the changed owner ID on the block chain of the computer group 420 .

In step S520, the ownership information processing unit 1121 of the management server 100 generates an encoded ownership management identification code from the blockchain hash value returned from the blockchain, the article ID, and the changed owner ID. Generate.

In step S530, the ownership information processing unit 1121 of the management server 100 transmits the generated ownership management identification code to the terminal device 300, which is the requester, and ends the process.

With the above-described owner change processing, when the ownership is transferred due to the sale of the item, etc., the change of the owner ID accompanying the transfer is recorded on the blockchain in a form that cannot be falsified. A producer/manufacturer who sells an article can provide a purchaser with an identification code for ownership management in which a change in ownership of the article is recorded, attached to the article to be sold. In addition, although the example in Figure 5 describes the case where the ownership is transferred from the producer/manufacturer of the goods to the purchaser of the goods, the same applies when the purchaser of the goods resells the purchased goods to others. The ownership transfer can be recorded in the system 1 by the processing of .

[Owner confirmation process]
Next, data processing executed when an owner of an article subject to ownership management in the ownership management system 1 confirms his or her own ownership will be described. FIG. 6 is a flow chart illustrating the data processing of the owner confirmation process.

In step S600, the ownership information processing unit 1121 of the management server 100 receives the owner confirmation request transmitted from the operation terminal 200 possessed by the owner of the article and the ownership management identification code held by the user. accept.

In step S610, the ownership information processing unit 1121 reads data recorded on the block chain of the computer group 420 based on the data including the owner ID recorded in the received ownership management identification code.

In step S620, the ownership information processing unit 1121 determines whether the owner ID recorded in the data read from the blockchain and the owner ID recorded in the owner management code received from the user's operation terminal 200 are Determine if it matches. If it is determined that the two match (YES in step S620), the ownership information processing unit 1121 generates ownership certificate data, transmits it to the operation terminal 200 that is the source of the request, and ends the process. On the other hand, if it is determined that the owner ID recorded in the data read from the blockchain does not match the owner ID recorded in the owner management code received from the user's operation terminal 200 (step S620 is NO), in step S640, the ownership information processing unit 1121 transmits to the operation terminal 200 of the request source that the information on the owner ID does not match, and ends the process.

According to the above owner confirmation processing, the owner of the article can confirm that he is the rightful owner of the article. Also, a system-issued certificate of ownership can prove to third parties that you are the rightful owner.

[Product authenticity determination process]
Next, article authenticity determination processing in the property right management system 1 according to the present embodiment will be described. As described with respect to the ownership management start process of FIG. 4, the system 1 can perform not only the ownership management of an article but also the authenticity determination process for the article. Authenticity determination processing is also executed using the identification code for ownership management issued to the owner of the article.

In this embodiment, when using the authentication service in the system 1, the user pre-installs a predetermined application provided by a management company that manages ownership management and authentication service on the operation terminal 200. there is Through this application, the user sets personal information for identifying an individual such as name and address, a user ID, and a password, and performs user registration with the management server 100 in advance. User registration information can be recorded in the service server 120, for example.

When the application is activated, a login screen 210 as shown in FIG. 7 is displayed on the operating terminal 200 . On the login screen 210, an entry field for a user ID and a password registered in advance and a login button 211 are displayed. When the login button 211 is selected, the application transmits the entered user ID and password to the service server 120 . The service server 120 performs authentication using the user ID and password, and displays the user screen 220 on the application when the authentication is successful.

As shown in FIG. 8, the user screen 220 displays a determination history button 221 that allows the user to refer to the history of authenticity determination, and a read button 222 that starts reading the two-dimensional code. The management server 100 records and manages (management means) the history of authenticity judgment performed for each user ID, and although not shown in detail in the figure, when the judgment history button 221 is selected, the history of authenticity judgment can be viewed. can be done.

When the read button 222 is selected, a read screen 230 as shown in FIG. 9 is displayed. The user causes the two-dimensional code C attached to the product at hand to be read while the reading screen 230 is displayed.

[Example of data processing for realizing authenticity determination processing]
FIG. 10 is a flow chart illustrating the authenticity determination processing performed by the authenticity determination processing unit 1123 of the management server 100 .
In step S1000, when the ownership management identification code is read in the user's operation terminal 200, the authenticity determination processing unit 1123 of the management server 100 transmits the read data to the management server 100 and receives it (accepting means ). The authentication processing unit 1123 of the management server 100 decrypts the received read data (extraction means), confirms whether the read data is used in the authentication service, and then, in step S1010, decrypts the data. to the management server 100 .

In step S1020, the decrypted data includes the blockchain hash value, item ID and owner ID. The authenticity determination processing unit 1123 of the management server 100 temporarily holds the decrypted article ID and owner ID, and in step S1030, accesses the computer group 420 and refers to data on the blockchain from the blockchain hash value. Next, in step S1040, the authenticity determination processing unit 1123 extracts the article ID and owner ID from the data on the blockchain referenced from the blockchain hash value, and extracts the article ID and owner ID from the user held in step S1020 The owner ID is collated with the article ID and owner ID referenced from the blockchain hash value in step S1030 to determine their matching relationship (determining means).

If it is determined that the two match (YES in step S1040), the authenticity determination processing unit 1123 determines that the article is a genuine article, and shifts to genuine article judgment output processing. On the other hand, if it is determined that there is no match (NO in step S1040), in step S1060, the authenticity determination processing unit 1123 instructs the operation terminal 200 to display a counterfeit product determination display indicating that it is a counterfeit product. Complete the authenticity determination process. The counterfeit product judgment display displays a message explaining that the product is a counterfeit product (see FIG. 13, which will be described later).

Also, if the blockchain hash value is not obtained in step S1030, the authenticity determination processing unit 1123 can obtain the blockchain hash value in step S1030, but the corresponding item ID does not exist on the blockchain. , the process of displaying the counterfeit judgment display in step S1060 is performed. If it is determined that the article ID matches but the owner ID does not match, a note to the effect that "the owner ID does not match" is output in the genuine product determination output processing described later. may be configured.

[Authentic product judgment output process]
Next, the genuine product determination output processing will be described using the flowchart of FIG. 11 and the screen example of FIG. 12 . First, in step S1100, the authenticity determination processing unit 1123 of the management server 100 determines whether the data on the blockchain referred to by the blockchain hash value includes a distributed hash value. If it is determined that the distributed hash value is included (YES in step S1100), in step S1110 the authenticity determination processing unit 1123 refers to the video data on the distributed file system from the distributed hash value. If it is determined that the distributed hash value is not included (NO in step S1100), in step S1140, the authenticity determination processing unit 1123 extracts various items including the article ID from the data on the blockchain referenced from the blockchain hash value. The text data of the information is displayed on the genuine product determination display screen 240 in the application, and the genuine product determination output process and the authenticity determination process are completed.

In step S1120, the authenticity determination processing unit 1123 extracts the video data referenced from the distributed hash value, converts it into a format that allows streaming playback, and then generates link information that enables streaming playback of the video data. Then, in step S1130, the authenticity determination processing unit 1123 causes text data and link information of various types of information including the article ID to be displayed on the genuine product determination display screen 240 of the application from the data referenced from the blockchain hash value. The genuine product determination output process and authenticity determination process are completed.

[Regular product judgment display]

FIG. 12 shows an example of a genuine product judgment display screen displayed as a result of the authenticity judgment processing. As shown in FIG. 12, on the genuine product judgment display screen 240, a text 241 explaining that the product is genuine, the name of the producer, the production date, the product ID 242, the name of the owner, the blockchain hash value 243, and the video A video viewing button 245 is displayed. The user can confirm that the product to which the read two-dimensional code is attached is a genuine product by displaying the genuine product determination display wording 241 as a result of the authenticity determination. In recent years, mail-order sales such as Internet shopping have become widely established, and there are many stores where you can purchase products. Being able to judge the authenticity of products by themselves is expected to increase the reliability of products in mail-order sales, which will be used more widely in the future, and to increase consumers' willingness to buy. It should be noted that the display items and display form of the genuine product determination display screen 240 are not limited to the example of FIG.

Further, on the genuine product judgment display screen 240, in addition to the text 241 explaining that the product is genuine, the name of the producer, the production date, the product ID 242, and the blockchain hash value 243 are displayed. A sense of trust can be obtained from the judgment. In particular, by displaying the blockchain hash value 243 on the genuine product judgment display 240, it can be seen that the data used for judgment is recorded on a blockchain that can strongly suppress falsification, and the product is said to be genuine. You can give confidence to your decision.

Furthermore, since the video can be viewed by selecting the video viewing button 245 of the video that is displayed only when the product is genuine, a sense of reliability can be obtained in determining that the product is genuine. You can know the thoughts and concepts that you want to convey about the product as a story, and you can satisfy your desire to own only genuine products.

[Effect of Fraud Prevention by Ownership Management System 1]
According to the property right management system 1 of this embodiment, a person who illegally acquires only an article to be managed does not have a two-dimensional code for obtaining the article ID and owner ID of the article. You cannot indicate that you are the owner. Therefore, since the article cannot be resold to others, fraudulent acts of pretending to be the owner are deterred.
In addition, even if an article to be managed and a two-dimensional code associated with the article are illegally acquired, when the illegal acquirer logs in to the property rights management system 1, the rightful owner cannot be identified. Since this is done based on different user information, it is not possible to request the ownership management system 1 to confirm the ownership of the article. Therefore, in this case as well, resale of the article by the person who acquired it illegally is deterred.
In addition, assuming a case where counterfeits of articles to be managed are produced and sold illegally, the production of counterfeit goods alone cannot prove the ownership of the counterfeit goods, so illegal sales are deterred. In addition, when a two-dimensional code corresponding to a genuine article is illegally duplicated, when a person who acquires a counterfeit article tries to change the owner using the property right management system 1, the owner of the genuine article Therefore, it is not possible to request the ownership management system 1 to confirm the ownership of the article. Therefore, in this case as well, the act of trying to obtain unfair profits from counterfeit products is deterred. Furthermore, it is assumed that the person who produced the counterfeit obtains not only the two-dimensional code corresponding to the genuine product but also user information (login ID, password) regarding the ownership management system 1 of the owner of the genuine product. In this case, the owner of the counterfeit product possesses the two-dimensional code of the genuine product and the system user information of the owner of the genuine product. It is conceivable that a transaction to resell the property to another person with good intentions may be established and the owner's record in the property right management system 1 may be illegally rewritten. However, in this case, the genuine product is owned by the original owner of the genuine product. It becomes clear that the owner has been unfairly changed to someone else even though he/she owns it. Therefore, it is considered that there is a sufficient deterrent to planning fraudulent acts such as the production and sale of counterfeit goods at the risk of the unauthorized sale of counterfeit goods being exposed later.
By adopting a two-factor authentication method added with short message service (SMS) authentication, etc., for the login process to the ownership pipeline system 1, a third party can access only user information such as the owner's login ID. In addition, it becomes impossible to log in to the ownership management system 1 unless the operation terminal 200 such as a smartphone used by the owner is obtained. By doing so, the resistance of the property right management system 1 to fraud can be improved.

The service server 120 of the management server 100 records a browsing history for each link information that enables streaming reproduction of generated video data. Specifically, terminal information such as the IP address and MAC address of the terminal that accessed the link information, that is, viewed the video, is recorded together with the date and time, and the number of accesses to the same link information, that is, the number of views, is counted. This browsing history information is uploaded and recorded on the blockchain. Therefore, it is possible to prevent falsification of information in the browsing history. In addition to recording the browsing history, the history of authentication requests may be recorded and managed for each article ID, which is article identification information, for each same article, or for each user ID.

Service server 120 displays a warning display 244 (see FIG. 12) indicating that the number of viewing times is large on genuine product determination display 240 when the number of times the video has been viewed exceeds a preset number, and the link information is sent to processing server 110. can be sent to According to this, when the number of browsing times is greater than the set number of times, it is suspected that the ownership management identification code itself has been duplicated and that a plurality of operation terminals 200 have requested authenticity determination. Therefore, it has the effect of encouraging consumers who see the warning label to check whether the product is genuine or not by inquiring with the retailer or producer/manufacturer.

In addition, the service server 120 records the browsing history for each link information that enables streaming playback of the generated video data, and also records the browsing history in the link information for each user ID. can be monitored for user IDs that perform

Furthermore, the service server 120 records a browsing history for each article ID, and monitors article IDs for which authentication requests have been made an unnatural number of times. Duplication of administrative identification codes can be suspected.

Further, when link information for streaming playback of moving image data is browsed, service server 120 receives position information (position coordinate data obtained based on GPS) in addition to date and time information from operation terminal 200 for browsing. This date and time information and location information are recorded in the browsing history information. According to this, when the date and time of a plurality of browsing histories are at the same time or close to each other for any of the same link information, the same user ID, or the same article ID, involvement with counterfeit goods is suspected. In addition, if the location information of multiple browsing histories is concentrated at the same location or close together in an unnatural number, it may be related to counterfeit products. Involvement of counterfeit products can be grasped in detail. In addition, since there is a possibility that browsing will be performed multiple times for testing at the factory of the producer of the item, the workshop of the creator, etc., by using the location information, the number of times of browsing at such a specific place should be excluded from the criteria for suspecting counterfeits.

In addition, the service server 120 can receive transaction information such as when buying and selling products, and records each transaction information for each article ID on the blockchain, and restores it from the identification code for ownership management. Based on the article ID obtained, the article may be browsed as necessary. According to this, traceability can be improved.

The processing server 110 records the item ID corresponding to the received link information in the alert list. A warning display is displayed on the genuine product judgment display screen 240 of the operation terminal 200 which is the source of the information of the corresponding identification code for ownership management. According to this, it is possible to promptly warn the consumer that there is a suspicion that the identification code itself for ownership management has been duplicated.

To summarize the configuration of the property right management system 1 in the present embodiment described above, the management server 100 stores an article ID, which is unique identification information attached by the product manufacturer to identify the product, and the owner of the article. An identification code for ownership management is generated from the owner ID, which is information for specifying, and the hash value acquired when the article ID was recorded on the blockchain. The producer or creator of the article can add the generated identification code for ownership management to the article and sell the article. A purchaser of an article can read an identification code for ownership management attached to the article using an operation terminal 200 such as a smartphone, and can request the management server 100 to confirm the owner and determine the authenticity of the article. The management server 100 restores the blockchain hash value, the article ID, and the associated owner ID from the information of the identification code for ownership management received from the operation terminal 200, and restores the restored blockchain hash value. Acquire the article ID and owner ID recorded on the blockchain using the method, determine the matching relationship between the article ID and the owner ID directly restored from the identification code for ownership management, and determine the determined matching relationship. It is configured to output to the operation terminal 200 . According to this, the purchaser of the article can easily confirm the owner and determine the authenticity simply by installing the application on the operation terminal 200 and reading the identification code for ownership management attached to the article. . In addition, the item ID attached to the item, the owner ID associated with it, and the blockchain hash value, which is the recording destination of the identification information, are associated only with the identification code for ownership management. In addition, there is no possibility that the information used for owner confirmation and article authenticity determination is falsified, and owner confirmation and authenticity determination can be performed with high reliability.

In addition, when it is determined by the authenticity determination process that the two item IDs match, that is, when determining that the item is genuine, the management server 100 allows the video data stored together with the item ID 18 to be viewable via the operation terminal. 2, the consumer can select the video viewing button 20 of the video that is displayed only when the product is genuine, and can watch the video. can gain confidence in

In addition, the management server 100 causes the computer group 410 constituting the distributed file system to store video data, associates distributed hash values, article IDs, and owner IDs, which are related data related to storage of video data, and stores them in a block chain. Since the correspondence between the video data and the article ID is recorded only on the blockchain, falsification of this correspondence can be prevented. , it is possible to prevent malicious replacement of video data.

In addition, since the management server 100 uses the article ID assigned at the time of production/manufacture of the article as the article identification information used for property right management and authenticity judgment, the management server 100 uses new identification information for property right management and authenticity judgment. , there is no need to prepare and manage new correspondence between identification information and article IDs, and there is no risk of malicious falsification. In other words, the reliability of owner confirmation and authenticity determination can be maintained by performing ownership management and authenticity determination using the unique item ID already assigned to the item.

In addition, the blockchain hash value, article ID, and owner ID in the identification code for ownership management can be restored only by the management server 100, and are not visible unless the product is determined to be genuine. . Therefore, even if the legitimate ownership management identification code is simply duplicated, it is difficult to match it with the article ID and the owner ID attached to the article. can be prevented.

In this embodiment, the management server 100 encodes the blockchain hash value returned from the blockchain, the article ID, and the owner ID to generate an identification code for ownership management. An identification code for ownership management may be generated based on the chain hash value, article ID, and owner ID, and a method other than encoding may be used.

In addition, the service server 120 receives a user ID from the operation terminal 200 when receiving a request for authentication, and records and manages the history of authentication for each user ID, so the management company can easily detect fraud. . For example, if the number of requests for authenticity determination is extremely large, it can be suspected that you are involved in the sale of counterfeit goods. It is possible to warn people against counterfeit products. Furthermore, by recording the history of authenticity determination on the blockchain, it is possible to prevent falsification.
The data processing by the service server 120 described above may be executed by another part of the management server 100, for example, the processing server 110. FIG.

As described above, according to one embodiment of the present invention, it is possible to provide an article ownership management system and an identification code for ownership management that enable proper management of the ownership of an article in the real world.

When the owner of an article is changed, the management server 100 that has received the changed owner ID associates the article ID of the article with the changed owner ID, records the changed owner ID on the blockchain, and records the changed owner ID on the block chain. A two-dimensional code as an identification code for ownership management can be generated from a block chain hash value acquired from the chain when recording, the article ID, and the owner ID information.
In this way, the change of the owner of the goods is recorded in the block chain in a form that virtually cannot be tampered with, so it is possible to effectively deter fraudulent acts such as illegal acquisition of goods and resale by impersonating the owner. can do.

Corresponding to at least one of the block chain hash value acquired from the block chain at the time of recording and the item ID, storing video data corresponding to the item related to the item ID in a distributed file system, and storing the video data The operation terminal 200 further includes a video processing unit that associates the link data related to the article with the article ID and records them on the blockchain. Based on at least one of the blockchain hash value extracted from the dimension code and the article ID, the video data corresponding to the article associated with the article ID can be output so as to be viewable.
In this way, only if the product is genuine, the user can view the video related to the product. You can know the thoughts and concepts that people want to convey about goods in the form of stories, and you can satisfy your desire to own only genuine goods.

The operation terminal 200 can be configured to output the extracted blockchain hash value together with the matching relationship when the authenticity determination processing unit 1123 determines that they match.
In this way, by displaying the blockchain hash value on the genuine product judgment display, it can be seen that the data used for judgment is recorded on a blockchain that can strongly suppress falsification, and the genuine product A sense of reliability can be imparted to the judgment that there is.

When performing the determination processing by the authenticity determination processing unit 1123, the history of determination can be recorded and managed for each article ID.
In this way, it is possible to extract an event that raises the suspicion of some kind of fraud, such as multiple determination requests for the same article ID.
