Description

Technical Field

[0001] This invention relates to the field of data element circulation technology, specifically providing a method and apparatus for data asset registration and storage. Background Art

[0002] To better manage and utilize data assets and ensure the healthy and orderly development of the data element market, data asset registration was established.

[0003] Providing authoritative information to the data market and assigning a unique product code / identifier to each data product entering circulation, along with issuing data asset registration certificates, helps ensure the security and compliance of data product circulation. Clearly defining data ownership and establishing legal liability for illegal activities based on registration facts are crucial questions that need to be addressed by those skilled in the art. Summary of the Invention

[0004] This invention addresses the shortcomings of the prior art by providing a highly practical method for data asset registration and storage.

[0005] A further technical objective of this invention is to provide a reasonably designed, secure, and applicable data asset registration and storage device.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] A method for registering and storing data assets, based on blockchain technology, includes the following steps:

[0008] S1. Log in to this blockchain management system;

[0009] S2. Upload the data asset registration certificate that needs to be stored;

[0010] S3. The system uses a redundancy fragmentation algorithm to fragment the uploaded electronic data;

[0011] S4. The system sorts the selected nodes according to their performance scores;

[0012] S5. Establish a corresponding mapping relationship between user information and the data that needs to be accessed;

[0013] S6. Verify the integrity of electronic data.

[0014] Furthermore, in step S1, the user node first broadcasts its own performance file to all nodes in the system. The system contract member class obtains user information and obtains the performance information of other user nodes through the user node, so as to obtain the value of the performance host for subsequent data sharding storage.

[0015] Furthermore, in step S2, the data asset registration certificate that needs to be stored is uploaded, and the key information of the document is written into the contract file class to establish a corresponding mapping relationship between users and data.

[0016] Furthermore, in step S2, the system uses a redundancy sharding algorithm to shard the uploaded electronic data, and then selects several nodes with the best performance based on the previously obtained node performance information to store the sharded data of the system.

[0017] Furthermore, in step S3, the system sorts the selected nodes according to their performance scores, distributes data to different nodes, and returns the distribution information to the smart contract, including the IP address of the data shard storage, the absolute path of the shard storage, and the hash value of the data shard.

[0018] Furthermore, in step S4, when a user needs to download or query electronic data, the system establishes a corresponding mapping relationship between the user information and the data to be accessed based on the user's request and authorization request, and then the user performs the operation.

[0019] Furthermore, in step S5, the system reads the relevant storage information of the electronic data from the contract, obtains the location of the electronic data storage through the storage information, downloads the electronic data fragments, restores the data, and compares the file hash value to verify the integrity of the electronic data.

[0020] A data asset registration and storage device includes: at least one memory and at least one processor;

[0021] The at least one memory is used to store a machine-readable program;

[0022] The at least one processor is used to call the machine-readable program to execute a data asset registration and storage method.

[0023] Compared with the prior art, the data asset registration and storage method and apparatus of the present invention have the following outstanding advantages:

[0024] This invention lays the foundation for the circulation and utilization of data. Through comprehensive, accurate, and meticulous registration, it issues data asset registration certificates, ensuring that data is traceable and verifiable in complex circulation networks. Storing data asset registration certificates on the blockchain provides crucial trust guarantees. Ensuring that registration information is on the blockchain allows both parties to understand key elements, building trust, reducing risk, and facilitating smooth transactions. The verification and auditing mechanisms during registration enhance data credibility, providing strong support for the circulation and utilization of data, while simultaneously reducing the cost of investigating information related to losses.
