The Internet of Things (IoT) system has a physical limitation of the device and a limitation of storing and computing the collected data in one cloud. In order to solve the limitations of such a centralized system, prior researches integrating the IoT and blockchain technology are being actively conducted. In order to implement data sharing services, system efficiency and user privacy are indispensable. To enable data sharing, these limitations must be overcome. This paper flexibly and robustly configures user’s access control through DACT using context attribute of Identity of Things (IDoT). In addition, the edge-type system configuration reduces the traffic overload caused by one cloud and combines the efficiency of the system. The system proposed in this paper can build a platform that can safely share users’ energy consumption data in the energy data sharing system.
