Research on the Sharing of Equipment Data Based on Blockchain

In today's big data era, the effective sharing of data is the basic link to make full use of data. However, there are a lot of security risks in this link. In particular, equipment data involves many secrets and cannot be completely open. Based on the almost immutable characteristics of blockchain, encrypted transmission, full chain consensus, and full process traceability, a set of security, privacy, and mutual trust is proposed. Equipped with data sharing solutions. Blockchain technology can effectively improve the credibility and security of data sharing links. In the overall framework, the blockchain, as the core of the data sharing system, guarantees reliable communication between different data centers and terminals, and realizes the entire process of encrypted transmission, and the original data "never exits the data holder's hard drive". It not only meets the demand side's use of data, but also avoids the risk of data leakage by the data holder, thereby eliminating the worries and worries of the data holder's information security.
