Blockchain Based Trustworthy Digital Twin in the Internet of Things

The combination of digital twin technology and the application of IoT(Internet of things) has been widely used. It manages the whole life cycle of IoT data by establishing a digital twin system of physical system. However, extracting effective insights from the collected data requires an infrastructure that can ensure the credibility of the data. We propose a data security sharing architecture based on dual Blockchain to solve the storage and security problems when data is invoked by third-party services. The architecture is applied to the Internet of things system based on digital twin to solve the data security transmission between physical system, digital twin system and IOT application system.
