The construction of special equipments, health detection and monitoring cloud platform starts the process of "service" of the whole industry, which can achieve a lot in service reuse and service precipitation.However "service" brings advantages as well as some challenges. Since it requires remote service calls and needs to share some industry data, data security and privacy protection during service invocation become a major problem, the solution of which is the focus of this paper. The establishment of the special equipment health detection system based on the consortium blockchain technology was proposed to solves the data security and privacy protection problems in the service invocation process, providing protection for service security and privacy to some extent.
