Abstract: With the rapid development of smart industry, the data acquisition ability of edge devices in the perception layer of smart factory is gradually improved. The security of Industrial Internet of Things has increasingly become a common focus. Aiming at the data security problem in the security of industrial Internet of things, combined with the current situation of industrial Internet of things equipment, this paper proposed an anonymous storage and verification model of industrial production status which is based on blockchain. The purpose of this paper is to ensure the storage security and efficient use of industrial production data. We improve the existing Industrial Internet of Things architecture and add blockchain to participate in smart factory privacy protection and data automation processing. On this basis, anonymous storage and verification algorithm for production status, DCB (Double Color Ball) algorithm, is designed. Finally, the simulation industry platform is built, and the architecture is realized by taking the simulation industry platform as an example. The proposed structure can verify data anonymously on the premise of ensuring data security through theoretical analysis and experiment. Besides, the IIoT system still maintains a low overhead.
