The operation phase of the industrial Internet involves multiple interactions,which makes the security protection effect of private data difficult to meet the actual application needs.Therefore,the research on the security protection of industrial Internet privacy data based on blockchain is proposed.A privacy data security management model has been constructed,in which the data generator establishes a trust mechanism and pools signature authentication,the data holder divides data attributes and hides sensitive information,and the blockchain network is responsible for controlling the interaction process.At the same time,access permission labels are used to constrain the access of data on the blockchain.The test results indicate that the proposed method has achieved effective protection against different types of attacks without any security issues.
