摘要
现有传染病预防信息系统在工作过程中存在数据难以流通和共享等问题。为了解决这些问题,借由区块链的去中心化、不可窜改和集体维护等特点,提出了一个基于DPoS共识算法的传染病数据共享模型。该模型采用双链结构作为区块链架构,提高了工作效率;结合IPFS获得大容量存储空间,解决了区块数据存储面临的空间问题,保障了数据存储稳定性与共享安全性;提出了疾病防控共识算法,实现了传染病数据共享模型的高效运行。此外,通过与其他数据共享模型的对比,突出了该模型在数据存储与共享安全等方面的优势。
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.
