[0053] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0055] Data elements are data assets that generate economic benefits in actual social production and operation activities. They are oriented towards the digital economy and refer to data in the context of discussing productivity and production relations, emphasizing the role of data in promoting production value. Data elements can be original data sets invested in production, standardized data sets, various data products, and systems, information, and knowledge generated based on data.

[0056] Data ownership, that is, data ownership, mainly focuses on who manages and uses the data, and how the benefits created are distributed. It is a complex and multi-dimensional issue, involving multiple aspects such as corporate rights and interests and personal privacy. There are problems such as difficulty in defining ownership, lagging laws and regulations, and difficulties in data security and privacy protection.

[0057] Blockchain is a new distributed infrastructure and computing method that uses blockchain data structures to verify and store data, distributed node consensus algorithms to generate and update data, cryptography to ensure the security of data transmission and access, and smart contracts composed of automated script codes to program and operate data. It is decentralized, tamper-proof, secure and reliable.

[0058] CMS is a software application used to create, publish, and manage website content. CMS allows users to manage the content of the website through a simple interface without having to delve into the underlying technical details of the website.

[0059] Restful API is an interface design method that uses HTTP (Hypertext Transfer Protocol) protocol for data communication. It is widely used to build network applications and services. In RESTful API, resources are the core concept and represent data entities in the application. Each resource is identified by a unique URI (Uniform Resource Identifier), and the client can perform CRUD (create, read, update, delete) operations on the resource through HTTP methods (such as GET, POST, PUT, DELETE).

[0060] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0061] In a first aspect, an embodiment of the present application provides a universal data element circulation and transaction method.

[0062] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the general data element circulation transaction method of this application. Figure 1 As shown, the general data element circulation transaction method includes:

[0063] S1: Register the data assets held by the data asset sellers based on the data registration platform, and publish the registered and reviewed data assets to the data trading platform;

[0064] S2: Constructing a transaction contract between the data asset buyer and the data asset seller, and implementing monitoring of data asset delivery between the data asset buyer and the data asset seller based on the transaction contract;

[0065] S3: Monitor the use and circulation of data assets by data asset users based on the data trading platform.

[0066] Furthermore, in one embodiment, the registration of data assets held by data asset sellers is implemented based on the data registration platform, and the data assets that have been registered and reviewed are published to the data trading platform, which specifically includes:

[0067] S101: The data asset seller registers the data assets it holds on the data registration platform and generates a certificate of ownership. The registration content includes the data generation process, pricing strategy, and rule documents. The rule documents are the rules and regulations that must be followed for the circulation and transaction of data assets.

[0068] S102: The data asset seller publishes the data assets registered and reviewed on the data registration platform to the data trading platform;

[0069] S103: The data trading platform reviews the legality and authenticity of data assets;

[0070] Among them, when publishing data assets to the data trading platform, the published content includes data content description, release scope, release time, and ownership certificate.

[0071] Specifically, data assets are first registered, titled and priced. The seller of data assets will register the data assets they hold on the data registration platform, including the data generation process, pricing strategy, rule documents, etc., and will eventually generate a certificate of ownership; then the data assets are published and listed. The seller of data assets will publish the data assets registered and reviewed on the data registration platform to the data trading platform. The data trading platform will review the published data assets to ensure the legality and authenticity of the data assets.

[0072] Furthermore, in one embodiment, constructing a transaction contract between a data asset buyer and a data asset seller specifically includes:

[0073] S201: The data asset buyer confirms the release of the data asset on the data trading platform;

[0074] S202: Building a transaction contract between the data asset buyer and the data asset seller through the data transaction platform;

[0075] Among them, the transaction contract includes the transaction object, contract signing date, payment method, data asset usage strategy, data asset circulation strategy, data asset fallback conditions, and data asset fallback method.

[0076] Specifically, the buyer is determined and the transaction contract is generated. The buyer of the data assets is determined after the data assets are released, and a transaction contract is reached with the seller of the data assets through the data trading platform.

[0077] Furthermore, in one embodiment, monitoring of data asset delivery between a data asset buyer and a data asset seller based on the transaction contract specifically includes:

[0078] Based on the transaction contract, the data trading platform monitors the delivery of data assets between the data asset buyer and the data asset seller. If the data asset is in a fully bought-out state, after the data asset delivery is completed, the data trading platform will change the data asset ownership certificate, identify the data asset buyer as the holder of the ownership certificate, and identify the data asset buyer as the data asset user.

[0079] Specifically, data assets are delivered and ownership is changed. Based on the transaction contract, the data trading platform monitors the delivery of data assets between data asset buyers and data asset sellers.

[0080] Further, in one embodiment, monitoring the use and circulation of data assets by data asset users based on the data trading platform specifically includes: based on the transaction contract, and monitoring the use and circulation of data assets by data asset users through the data trading platform;

[0081] Among them, the monitoring content includes data asset usage strategy, supplementary data asset usage strategy determined by the stakeholders of data assets, and supplementary data asset circulation strategy based on and determined by the stakeholders of data assets; among them, in the process of data asset usage and circulation, a unified Restful API interface is used and the HTTP protocol is adopted for interface calls and data transmission.

[0082] Specifically, the use and circulation of data assets are monitored, and the data trading platform monitors the use and circulation of data assets by data asset users based on the transaction contract. In the use and circulation of data assets, all parties can independently develop, configure and deploy them, and use a unified Restful API interface and HTTP protocol for interface calls and data transmission. Data asset users can customize development and replacement by module.

[0083] Furthermore, the general data element circulation transaction method of the present application also includes:

[0084] A: Data asset stakeholders determine the data destruction strategy;

[0085] B: Based on the data destruction strategy, the data trading platform monitors the destruction of data assets by data asset users. At the same time, the data trading platform sends the evidence of data asset confirmation, release, transaction, delivery, use and destruction to the evidence depository for evidence storage.

[0086] Specifically, data assets are destroyed and stored. The stakeholders of data assets determine the data destruction strategy, and the data trading platform monitors the destruction of data assets by data asset users. At the same time, the data trading platform sends the evidence of data asset confirmation, release, transaction, delivery, use, and destruction to the storage party for storage to ensure the traceability and security of data assets.

[0087] The universal data element circulation and transaction method of the embodiment of the present application improves the efficiency of data circulation, realizes the rapid release, transaction and delivery of data through the data trading platform, reduces transaction costs and market frictions, and improves the efficiency of data circulation; ensures data security, ensures the security and compliance of data in the circulation process through the data review, ownership change, use monitoring and destruction strategy of the data trading platform, and avoids the risk of data leakage and abuse; solves the problem of data rights confirmation, clarifies the ownership relationship of data through the ownership confirmation mechanism of the data trading platform, solves the problem of data rights confirmation, and provides a solid legal basis for data circulation and transaction; promotes the release of data value: through the release, transaction and circulation of data assets on the data trading platform, it promotes the release and maximum utilization of data value, and provides strong support for the development of the data economy; enhances the fairness of data transactions, and enhances the fairness and transparency of data transactions through the transaction contract, ownership change and evidence storage mechanism of the data trading platform, and protects the legitimate rights and interests of all parties.

[0088] On the second aspect, the embodiments of the present application also provide a universal data element circulation and transaction system.

[0089] In one embodiment, referring to Figure 2 , Figure 2 This is a functional module diagram of the general data element circulation and trading system of this application. Figure 2 As shown, the general data element circulation and transaction system includes: user module, data registration platform, data transaction platform, authentication authority service, workflow service, design portal, blockchain service, and data dictionary service.

[0090] Specifically, a general data element circulation and trading system, or a general data element circulation and trading platform should be composed of three main bodies: users, data registration, and data trading mall, as well as basic services such as authentication permissions, workflow, log monitoring, blockchain, design portal, and data dictionary.

[0091] The user module is used to implement the registration and login of data asset sellers and data asset buyers. Specifically, the user module can be an Internet-oriented mini-program that needs to support the registration and login of enterprises, institutions, and operation managers.

[0092] The data registration platform is used to realize the registration, title confirmation and pricing of data assets; the data trading platform is used for the listing of data assets by data asset sellers, as well as the release of needs and order placement by data asset buyers, as well as the signing of transaction contracts and the delivery of data assets.

[0093] The authentication and authority service is used to perform real-name authentication for data asset sellers and buyers, activate services, and display, allocate, and manage permissions; the workflow service is used to define, trigger, and circulate business processes involved in data asset circulation transactions, such as user real-name review, data registration review, data product public listing review, contract signing review, etc.

[0094] The design portal is used to provide custom combination and arrangement capabilities of front-end page resources to meet different project display requirements. The design portal module is a custom function and can be selected.

[0095] Blockchain services are used to provide encryption and verification functions through smart contracts to ensure the security of data asset circulation transactions. The technical solutions and contracts of the blockchain service module need to be customized and can be used directly or re-implemented.

[0096] The data dictionary service is used to provide definitions and queries of domain knowledge data involved in the circulation and exchange of data assets, such as administrative divisions, industries, data types, delivery methods, etc.

[0097] In actual applications, the life cycle of data element circulation transactions can be divided into the following processes: seller registration, seller release, buyer order placement, buyer and seller contract signing, and delivery. Mini programs only have the function of viewing and browsing, so the data flow mainly describes the browser mode. Specifically:

[0098] a) Users register an account using their mobile phone number. After registration is completed, they can conduct real-name authentication for personal, corporate, or institutional identities as needed. The authentication information will be transferred to the operation center, and the real-name authentication business will be approved and transferred through the workflow service;

[0099] b) After the real-name authentication is completed, taking enterprises as an example, they need to apply to open the data asset seller or data asset buyer business. After the operation center approves it, they can register and publish their own data products, or buy and sell the published data products. The data asset seller will access the data registration function and enter the information of their own data assets. The operation center will review the attachments of the data assets (such as enterprise information, data samples, third-party ownership certificates, etc.) provided by the data asset seller. After the review is passed, the corresponding ownership certificate will be generated. The data asset seller will publish the registered data assets as data products in the trading mall. The publishing process needs to describe the industry, price, type, supported delivery form, ownership certificate and other information of the product. After approval by the operation center, the product enters the public announcement stage. If there is no objection to the public announcement, it will be transferred to the product hall for display and sale;

[0100] c) After searching through the product hall and locking in their target products, data asset buyers can initiate an order operation, and the transaction contract signing process will be automatically initiated. The content of the transaction contract will clearly define the circulation strategy of the data product. After the transaction contract content is reviewed by the operation center and the two parties complete the signing process, they will enter the payment delivery process. According to the selected delivery method, the data product can be delivered offline or online. The online delivery process requires the corresponding data interface document, including the interface address, parameters, secret keys, usage samples, etc.

[0101] d) After the order payment is completed, if the transaction contract stipulates that the product is fully bought out, the data product will be removed from the mall and the data ownership will be transferred to the data asset buyer, and the transaction process will end;

[0102] e) In addition to the commodity buying and selling functions, there is also a demand matching function. The data asset buyer's data usage needs usually also need to go through the data demand release, review, order placement, contract signing, and delivery process.

[0103] It should be noted that blockchain undertakes the data existence and verification functions throughout the entire life cycle to ensure the traceability and security of data. The data circulation strategy mainly defines whether the data can be resold, whether it is destroyed after use, whether it is completely bought out, etc. It also supports custom strategies.

[0104] In a third aspect, the present application embodiment provides a universal data element circulation transaction service architecture for implementing the universal data element circulation transaction method described above, see Figure 3 As shown, the general data element circulation and transaction service architecture includes: front-end display layer, back-end business layer, and public component layer.

[0105] The front-end display layer includes login and registration, home page, product hall, demand hall, transaction hall, personal center, policy consultation, information release, problem feedback, and help center; the back-end business layer includes user management, product services, demand services, order services, and delivery flow monitoring; the public component layer includes log monitoring services, authentication authority services, workflow services, design portals, data dictionary services, and blockchain services.
