Abstract

The embodiment of the invention discloses a trusted data transmission method, device and equipment. Aproxy service party executing the method belongs to an authorization service party of a blockchainand belongs to a trusted service, and the trusted service can perform data interaction with a blockchain network; the method comprises the steps of obtaining a data use request of a data demander; obtaining authorization information of a data holder; generating a data authorization use declaration based on the authorization information, and obtaining initial data based on the data authorization use declaration; verifying the initial data to obtain target data carrying a data validity declaration after the verification is passed; and sending the target data to the data demander.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a trusted data transmission method, device and equipment. Background technique [0002] Blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data. Information cannot be forged and tampered. Transaction confirmation on the blockchain is completed by all nodes on the blockchain. [0003] The distributed network is the infrastructure of the blockchain. The data generated on each node is broadcast to other nodes through the distributed network, and other nodes verify the authenticity of the data through the proof of work. Data transmission, security and privacy are very important basic features, especially in the financial field, personal and corporate asset data are private data, and its security needs to be paid special attention to. If these data are transmitted at will, it will be It poses a great security ri...
