Description

Distributed prenatal screening information processing system combined with blockchain Technical Field The invention relates to the field of Internet of things, in particular to a distributed prenatal screening information processing system combined with a blockchain. Background Prenatal screening data is an indispensable part of hospitals, diagnosis and treatment processes and scientific research, and most important data and information of hospital systems and patients are basically stored in modern storage media, and part of important data and possibly stored in a memory module of a system terminal such as a Personal computer, a PDA (Personal digital assistant), a server or other removable memory modules, and the data are relatively isolated and stored in an in-hospital information system file and cannot be associated with an out-of-office consultation file. When a series of actions such as data sharing and the like are performed by cooperation among medical institutions, the problems of untimely information interaction, leakage of patient information and the like, and time cost increase can occur. In addition, the data do not have encryption characteristics, so that an illegal user is likely to acquire the original data of the storage module on the server, and personal privacy is seriously threatened. In the traditional prenatal screening method, related data of pregnant and lying-in women are sent to a unified server in a concentrated mode, the traditional cloud processing mode is high in network demand, the core network is high in pressure, and prenatal screening information detection results are slow to return. Therefore, it is necessary to build a distributed prenatal screening information processing system, and the platform is used for collecting, preprocessing, managing and uniformly using related data, so that more rapid and convenient information inquiry and management service is provided for medical staff for prenatal screening diagnosis, the prenatal screening health management work efficiency is improved, and meanwhile, the safety of related privacy data of pregnant and lying-in women and the uniqueness of the use purpose are ensured.
