Cui Xiaohui, Director of the Big Data and Cloud Computing Laboratory of Wuhan University, and a Ph.D. student at Wuhan University ’s National Cyber Security Institute jointly issued a document "How to Improve the Emergency Response Capability of Public Health Events of" Blockchain + Big Data "" In the emergency management system, key technical barriers such as cross-departmental data collaboration sharing, multi-source integration, full trace, privacy protection, security and credibility are broken. From the current perspective, "blockchain" has great potential. In the field of epidemic emergency management, blockchain + big data has been used in epidemic monitoring and early warning, epidemic information disclosure and collaboration, and material dispatch in epidemic areas.
The article pointed out that in the future, more blockchain-based multi-party collaborative epidemic prevention and control platforms need to be developed. Considering the stable demand factors under major public health events, when the early epidemic information is not suitable for public disclosure, use blockchain encryption and traceability technology to provide relevant information to clinicians, health experts, local disease control and government departments Provide controllable information sharing and provide corresponding channels to provide an effective platform for multiple parties to participate in the discussion and decision-making of the epidemic.
