Abstract

The infectious disease prevention information system has the problems that data is difficult to circulate and share between monitoring systems. To solve these problems, this paper proposed an infectious disease data sharing model based on delegated proof of stake consensus algorithm combined with blockchain technology. By virtue of the characteristics of the blockchain, such as decentralization, non-tampering and collective maintenance, it used double-chain as the blockchain architecture, which improved the work efficiency. Combined with inter-planetary file system, it obtained large capacity storage space, which solved the space problem faced by block data storage and ensured the stability and sharing security of data storage. This paper proposed a consensus algorithm for disease prevention and control to realize the efficient operation. In addition, by comparing with other data sharing models, the advantages of this model in data storage and sharing security are highlighted.
