Abstract:

【Purpose/significance】Epidemic prevention and control is closely related to the vital interests of the people. It is of great

significance to improve the efficiency of epidemic prevention and control by studying the new epidemic prevention and control information system and using blockchain technology to unite the whole society to fight the epidemic.【Method/process】Firstly, this paper analyzed the deficiencies in the prevention and control of COVID-19, introduced the characteristics of blockchain technology such as dis tributed storage, tamper-proof and traceability, studied the feasibility of applying blockchain technology to epidemic prevention and control information system. Then a model of epidemic prevention and control information system is built based on blockchain technology. The hierarchical architecture, overall architecture, operation mechanism and guarantee mechanism of the model were expounded.【Result/conclusion】The model has the advantages of strong sharing ability, strong scalability and high security. It is helpful to improve the efficiency of epidemic prevention and control.【Innovation/limitation】The innovation is that we introduce the blockchain technology into the epidemic prevention and control information system model which adopts the parent-child blockchain mode combining management chain and multiple blockchains.
