Abstract

The invention belongs to the technical field of data sharing, and discloses a blockchain-based data sharing system, which comprises: a blockchain module comprising a plurality of mutually matched blockchain nodes and realizing data sharing through the blockchain nodes; an access application module which is used for providing a data access node with permission setting for a user of the sharing system, wherein the user accesses the shared data in the block chain module through the data access node; an encryption authentication module which is used for verifying whether a blockchain node in the blockchain module and a data access node in the access application module are valid or not, deleting invalid blockchain nodes and performing encryption authentication on the valid blockchain nodes; anda data storage module which is used for carrying out distributed storage on the shared data in the blockchain module and the user information in the shared system based on IPFS. In conclusion, on thebasis of the blockchain technology, data sharing is achieved, and the risk that data is tampered can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of data sharing, and in particular relates to a blockchain-based data sharing system. Background technique [0002] With the development of technology, in the face of different types of data, how to efficiently realize the storage, transmission and sharing of sensitive data has become an urgent problem. The traditional data sharing technology solution is to use a third-party centralized system to store and use the data of all users. Users themselves cannot actually control the data, and there is a risk of privacy leakage; and, the traditional centralized information management system mode, there is Insufficient server stability, regional restrictions, and low data access efficiency. [0003] Blockchain is a distributed shared digital ledger supported by cryptography and stored in chronological order. Blockchain technology is favored for its decentralization, openness, transparency, and non-tamperability. It...
