Abstract

The invention discloses a blockchain data transaction system and a blockchain data transaction method based on proxy re-encryption and an intelligent contract. The system comprises a data owner terminal, a database system, a blockchain system, a data demander terminal and an intelligent contract module. According to the method, the security privacy of the transaction data can be ensured by using the proxy re-encryption technology, and the efficient and automatic execution of the data transaction can be realized by using the smart contract, so that the security privacy and efficiency problems of the blockchain data transaction are solved. The economic value of the data is realized, and the application value of the data is brought into full play.

Description

technical field [0001] The invention relates to the technical field of blockchain data transactions, in particular to a blockchain data transaction system and method based on proxy re-encryption and smart contracts. Background technique [0002] With the advent of the digital age, people can collect various types of data at low cost, multi-terminal, and multi-dimensional, and store them in a large amount in a certain system to complete the inventory of business goals. On the original information island, most of the data was left idle. In order to give full play to the role of data, these data sources were integrated and then merged to break the data island and become other external information or data resources required for decision-making. After circulation Use it again to generate more value and improve data usage. [0003] In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequentially connected manner in chronological order, and...
