Confidentiality and security are the key points in data use. For data sharing, through the research and analysis of some platforms based on block chains and trusted computing, this paper puts forward a security data sharing platform scheme with clear roles to improve the platform role building process and encryption design. Design a data sharing platform with clear process and moderate number of objects. The Trusted Computing Platform (TEE) in this scenario provides a secure computing environment to ensure its neutrality and security. The communication process uses asymmetric encryption to ensure reliable transactions and block chain technology which cannot be tampered with and traceable to the source. It also increases the traceability and monitoring ability while keeping data confidential, to avoid information leakage and inefficiency.
