Abstract
[Purpose/Significance]With the rapid development of the Internet of Things and its accelerated penetration into various industries,the Internet of Things has become a key infrastructure supporting the development of the digital economy in the digital society.Digital and intelligent IoT devices bring convenience to people,but also face the risk of privacy data leakage.[Method/Process]By analyzing the privacy data security threats existing in the Internet of Things,sorting out the relevant technologies of Internet of Things security and privacy protection,a blockchain based Internet of Things privacy protection scheme is proposed.[Results/Conclusion]Blockchain has the characteristics of decentralization,traceability,and tamper resistance.In order to improve the security of IoT privacy data,this article integrates blockchain technology with IoT and constructs an IoT privacy data protection scheme based on the consortium chain.The data collected by IoT devices is encrypted and stored in the IPFS and uploaded on the chain.Attribute based access control policies are deployed in the chain code to improve the security of IoT privacy data and reduce the risk of leakage.
