Abstract

The invention discloses a data sharing method and device.The method comprises the steps that shared data needing to be shared and basic information of the shared data are stored locally, and the basic information of the shared data is synchronized to other nodes of a block chain so that the other nodes can search and initiate downloading; and receiving an instruction of requesting to download the shared data sent by other nodes, wherein the instruction comprises identity authentication information of the node sending the downloading request, performing identity authentication on the node sending the downloading request through the identity authentication information, and if the identity authentication is passed, sending the shared data to the node sending the downloading request. Therefore, compared with a data sharing mode of cloud storage, the shared data does not need to be uploaded to a centralized server, the shared data does not need to be downloaded from the centralized server, the shared data can be queried, the shared data can be downloaded only through data transmission between the nodes, and the data sharing efficiency and the sharing flexibility are improved.

Description

technical field [0001] This application relates to the technical field of blockchain, and more specifically, relates to a data sharing method and device. Background technique [0002] With the development of Internet technology, a large amount of data has poured into the entire Internet, and the world has entered the "big data era". However, big data also brings inevitable problems, such as data security issues, data privacy issues, data copyright issues, etc., which eventually lead to the problem of "information islands" and the unwillingness of data sharers to share high-quality data. [0003] Data sharing based on cloud storage is an effective solution to the problem of "information islands". Data owners can store data in the cloud and share it through the cloud. Users can also access the data through the cloud center to achieve the purpose of data sharing. . [0004] However, since the shared data of cloud storage are all stored in the centralized cloud, the performanc...
