Abstract

The invention relates to the field of information security, and relates to a security big data privacy protection sharing method based on a block chain. A plurality of data storage parties and a plurality of data sharing parties are set, each data storage party is remotely connected with a storage cloud platform, and each data sharing party is remotely connected with the storage cloud platform; ablock chain network is set, wherein all the data storage parties and all the data sharing parties are used as connection nodes in the block chain network; the data protection sharing method comprisesa process of carrying out encryption protection on data, and further comprises a process of sharing the data. The technical scheme has the beneficial effects that a blockchain technology is used for providing data integrity verification and key management, and the problem that a semi-trusted cloud platform tampers security data and the problem of single-point failure of attribute authority are solved respectively.

Description

technical field [0001] The invention relates to the field of information security, and relates to a block chain-based security big data privacy protection sharing method. Background technique [0002] In recent years, with the rapid development of cloud computing and other technologies, the security field is undergoing a revolution. The improvement of security systems has reduced the time for disease diagnosis and brought great convenience to people's lives. The emergence of a secure big data sharing system based on cloud computing technology enables individuals to store, manage, and share their personal security data conveniently. Security data is a precious security resource. Reasonable sharing of security data can speed up the diagnosis and research of diseases and bring benefits to the entire security system. [0003] In the secure big data sharing system, due to data storage pressure and for the convenience of resource sharing, personal privacy usually stores personal ...
