Data sharing methods and data sharing network based on block chain and electronic equipment

Abstract

The invention discloses data sharing methods and data sharing network based on a block chain and electronic equipment. A data sharing method comprises the steps that a first user node broadcasts a first access request corresponding to to-be-acccessed data to the block chain; a submission node generates a corresponding shared token based on the first access request and feeds back the shared token to the first user node; the first user node initiates a second access request to a second user node corresponding to the to-be-accessed data through utilization of the shared token and an access license agreement; the second user node verifies the first access request based on the shared token and evaluates the access license agreement to obtain an evaluation result; and the first user node accesses the to-be-accessed data according to the access license agreement when the evaluation result indicates that the access license agreement passes the evaluation. In the mode, data circulating securityand compliance in a block chain network are improved.

Description

technical field [0001] The present application relates to the technical field of block chain, in particular to a data sharing method, data sharing network and electronic equipment based on block chain. Background technique [0002] Blockchain technology is a collection of new application technologies of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. From a data point of view, the blockchain is a chained data structure that combines data blocks in a sequentially connected manner in chronological order, and the data structure is cryptographically guaranteed to be tamper-proof and unforgeable. From a technical point of view, blockchain technology integrates a variety of different technologies. By building a blockchain network, each node in the network is allowed to obtain a complete copy of the data block, and based on the consensus mechanism and competitive computing To maintain the update of b...

[0004] However, while cloud audit brings convenience to the audit business, it also faces challenges from internal and external security issues of audit data

First of all, at present, the audit data is firstly collected by the agencies stationed in the audit object, and then uploaded to the central cloud database for centralized management. Long time and high cost

In addition, when the audit data is uploaded to the cloud database and called by multiple organizations, its transmission is not highly encrypted, and it is easy to be cracked by hackers, resulting in data leakage and unauthorized abuse, copying, or even selling of audit data.
