Cooperative infectious disease prevention and control system based on alliance chain and public chain

Abstract

The invention discloses a cooperative infectious disease prevention and control system based on an alliance chain and a public chain. An alliance chain network and a public chain network are constructed, communities, enterprises and scientific research institutions are accessed to the public chain network, and a virtual mechanism composed of a prevention and control center, a medical institution and the public chain is accessed to the alliance chain network; each institution in the alliance chain correspondingly serves as a local client node of federal learning, infectious disease risk assessment model training is carried out in a local data center, parameters obtained through training are uploaded to a federal server to execute safety parameter aggregation by using a federal learning method, and a final global infectious disease risk assessment model is obtained after federal learning iteration. According to the method, the block chain is used as a basic technical framework, data authenticity can be guaranteed on the basis of fully guaranteeing data security, privacy, rights and interests and the like, meanwhile, multiple parties are effectively stimulated to cooperate and share real data, and finally, the infectious disease risk level is evaluated.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular to the field of infectious disease prevention and control, and constructs a collaborative system for the prevention and control of infectious diseases based on alliance chains and public chains. Background technique [0002] At present, the data stored in the data center of a single medical institution is extremely limited, and more infectious disease data are collected and shared by various institutions. In the process of collaborative prevention and control of infectious diseases, relevant institutions are bound to have access to more medical data related to patients' conditions, but the medical data of patients involves various privacy, which not only involves the confidentiality of patients' personal information, but also concerns various organizations Organizations are worried that data sharing may improve the service quality of competitors, thereby enhancing the c...

Problems solved by technology

[0003] Purpose of the invention: In view of the vertical reporting mode of the traditional infectious disease reporting system, which leads to the inability of various medical institutions, disease prevention and control centers, and infectious disease research centers to share information and data such as medical treatment and infectious diseases, the present invention provides a method based on alliance chain and The collaborative system for the prevention and control of infectious diseases on the public chain uses blockchain technology to build an alliance chain between institutions to achieve horizontal and in-depth effective collaboration, and cooperates with various institutions on the public chain to form smart contracts to encourage components to be deployed on the public chain network. To effectively motivate organizations to cooperate and share real data, the public chain network eventually becomes a node of the alliance chain in the form of a virtual organization
