An Exploratory Study on the Design of Emergency First Aid Privacy Protection Computing System Based on Blockchain

The COVID-19 epidemic at the end of 2019 is a typical global public health event. It has spread to more than 200 countries around the world. In the face of sudden illness, the emergency department is the first choice for most patients, and it is often the first to grasp the basic situation of patients. In the process of processing the data of the emergency big data center, how to ensure the privacy of patients while using medical data reasonably. This paper mainly takes the data of the emergency big data center as the research object. Put important health data on the block chain to ensure that important data remains traceable throughout the process, cannot be tampered with, multi-point maintenance, unified standards, and realize the formation of emergency block chains, and use important health data based on privacy applications, Realize the historical traceability of data usage. At the same time, the calculation process of privacy calculation can also be uploaded to the chain, which can be used for data storage, auxiliary calculation, etc.
