Medical data management system based on block chain

Abstract

The invention discloses a medical data management system based on a block chain. The system is used for solving the problems that an existing medical data management system does not screen medical data, and though data are found, the data quality is poor, the medical data are not reasonably stored, and storage redundancy of storage nodes of a block chain is not reduced. The system comprises a medical data acquisition module, a data encryption module, a node distribution module, a server, a node acquisition module and a block chain node module. According to the method, medical data is screenedthrough node storage values, so that the data with relatively high quality in the medical data is selected and stored; by acquiring and analyzing information of a block chain storage node to obtain acoincidence value of the block chain storage node, the block chain storage node is reasonably selected for storage through the coincidence value; node allocation data is deleted and compressed for storage through the management value, so that the storage redundancy of block chain storage nodes is reduced.

Description

technical field [0001] The invention relates to the field of medical data management, in particular to a blockchain-based medical data management system. Background technique [0002] Medical institutions have always faced the problem of being unable to securely share data across platforms. On the one hand, data is scattered, and different medical institutions and different information systems form data islands, making it difficult to achieve a unified view centered on residents. Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It is widely used, such as the management of medical data; [0003] The existing medical data management system has data found, but the data quality is found to be very poor, and the data quality is not well controlled. At the same time, the medical data is not properly stored and the storage redundancy of blockchain storage nodes...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a medical data management system based on block chain; it is used to solve the problem that the existing medical data management system does not screen the medical data, which leads to the phenomenon that the data is found, but the quality of the data is found to be very poor and there is no Reasonable storage of medical data and reduction of redundant storage of blockchain storage nodes; the present invention collects medical data and combines the treatment duration and treatment cost to analyze the beaten node storage value, and uses the node storage value to analyze the medical data. Screening to select high-quality medical data for storage; through information collection and analysis of blockchain storage nodes and combined with the remaining memory of blockchain storage nodes, rated memory and storage distance to calculate the block The coincidence value of the chain storage node, through the coincidence value, reasonably selects the blockchain storage node for storage; deletes and compresses the data allocated by the node through the management value, thereby reducing the storage redundancy of the blockchain storage node;
