IoT data association based on blockchain smart contracts solves the problems of difficulty in confirming ownership of personal data, quantitative tracking of data assets and inability to efficiently complete value transfer in IoT systems. Transfer the right of control and control from the equipment manufacturer to the user to confirm the ownership of personal data; store the equipment status and data hash value in the blockchain through technologies such as full life cycle management and digital signatures to ensure the reliability of the data; use intelligent The contract construction goes to a third-party data trading platform to ensure the security of data sharing, and to easily complete data realization and data value transfer. The quantitative analysis results of attack possibility and attack success probability show that blockchain smart contract technology can provide defense against data Tampering, eliminating trust problems in data transactions. With the help of blockchain innovative contract technology, physical Internet data can be capitalized initially, and the data value transfer and sharing of Internet of Things devices can be promoted.
