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.
