[Abstract] Based on the characteristics of the Internet of things (IoT) platform, a blockchain system framework applied to the identity authentication of the body area network is proposed, which combines blockchain technology with body area network. This framework realizes the identity authentication between users and sensors, routers and multi servers. Then the feasibility and security of the framework are analyzed. Finally, based on the research results, the possible problems and future development directions of blockchain technology in the IoT platform are discussed.
