Problems solved by technology
This method has hidden dangers in security. For example, during the entire data transmission process, the data may be eavesdropped, the data content may be tampered with, and the identity of the data sender may be impersonated, etc.
In addition, in resolving disputes in the data sharing process, this method is difficult to quickly provide trustworthy evidence, which will bring loss of interests to both parties of the data. For example, the data provider shares the data, but the data user cannot obtain the data. At this time, the interests of the data user suffer losses; or, the data user does not recognize the behavior of obtaining data on the premise of obtaining the data, and the interests of the data provider suffer losses at this time

The present application discloses a blockchain-based data security sharing method and device. Among them, the method applied to the data provider terminal includes: uploading the URI of the shared data received from the proxy server to the decentralized application of the blockchain; processing the application access request sent by the data user terminal and returning the processing result; When the data user terminal obtains the URI and sends the data access request to the proxy server, it receives the data access request and forwards it to the decentralized application for verification; receives the verification result and sends it to the proxy server, and if the verification is passed , the proxy server sends the access result of the shared data to the data user terminal. This method uses the blockchain to record various information in the process of data sharing, so that various records are true and cannot be tampered with, and identities cannot be impersonated, which greatly improves the security of data sharing and can provide credible evidence for disputes in the data sharing process Record.
Description
technical field [0001] The present application relates to the technical field of information security, in particular to a blockchain-based data security sharing method and device. Background technique [0002] The security of data sharing is a very important issue to be faced when data is shared by data providers to data users in the Internet environment. In the prior art, servers that provide external data sharing services usually use the secure communication protocol HTTPS to implement data sharing. This method has hidden dangers in security, for example, during the entire data transmission process, the data may be eavesdropped, the data content may be tampered with, and the identity of the data sender may be impersonated and so on. In addition, in resolving disputes in the data sharing process, this method is difficult to quickly provide trustworthy evidence, which will bring loss of interests to both parties of the data. For example, the data provider shares the data, b...
