Abstract

The embodiment of the invention relates to the technical field of data transmission, and discloses a blockchain-based data transmission method, device and system. The method comprises the following steps: receiving an encrypted data packet sent by a provider, wherein the data packet is a data packet comprising relevant data information exported by the provider according to a data request sent by arequester, and a public key of the requester; decrypting the data packet according to a preset decryption mode to obtain the relevant data information and the public key of the requester in the datapacket; processing data contents in the relevant data information according to a preset processing mode, encrypting the processed data contents through the public key of the requester, and sending theencrypted data contents to the requester; and destroying the data packet. The blockchain-based data transmission method, device and system adopting the technical scheme has the advantages that the requester can only use the data provided by the provider, instead of seeing or exporting the data, so that the provider can truly control the data provided by the provider; and therefore, data use can be effectively restricted, high data transmission safety is ensured, mutual cooperation among different departments is promoted, and the work efficiency of the departments is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data transmission, and in particular to a blockchain-based data transmission method, device, and system. Background technique [0002] In many cases, due to business needs, different departments need to cooperate to achieve data sharing. That is, the work execution of a certain department needs the support of source data or related data of related departments. However, some data of relevant departments are sensitive data and should not be shared directly with others. Due to "trust issues", departments are also worried that other departments will modify or reuse their own department's data. Once the data flows out, it will no longer be under their own control, so they are unwilling to share data. This makes it difficult to achieve mutual cooperation between various departments, which greatly affects the efficiency of the department, and even adversely affects the relevant depart...
