Abstract

The embodiment of the invention relates to the field of data transmission technology, and specifically discloses a data transmission device and system based on a blockchain. The data transmission device includes: a first data communication unit, which is used for receiving an encrypted data packet sent by a provider client; a processing unit, which is used for decrypting the data packet accordingto a preset decryption manner, acquiring data-related information in the data packet and a public key of a requesting party, processing data contents, which are contained by the data-related information, according to a preset processing manner, and then using the public key of the requesting party to carry out encryption; and a second data communication unit, which is used for feeding back data contents, which are encrypted by using the public key of the requesting party, to a requesting party client. The processing unit is also used for destroying the data packet. The requesting party can usebut cannot see or obtain data provided by a supplying party, and an effect that the supplying party dominates the data provided thereby is truly realized. Data transmission security is effectively guaranteed, mutual cooperation among different departments is promoted, and transaction efficiency of the departments is improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of data transmission, and in particular to a blockchain-based data transmission 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 departments. ...
