Blockchain-based medical electronic medical record distributed management system and construction method thereof

Abstract

The invention discloses a blockchain-based medical electronic medical record distributed management system and a construction method thereof. According to the blockchain-based medical electronic medical record distributed management system and the construction method thereof, the diagnosis processes of patients, such as medical records and prescriptions, are written into a blockchain in the form of smart contracts, so that a relevant hospital does not need to rely on a centralized server to manage the medical record information of the patients, and single-point failures common to the centralized server can be avoided; the data stored in the blockchain cannot be tempered and are traceable, and therefore, illegal tampering can be prevented; and a series of information such as the physical health, medical histories, and personal data of the patients, which concern personal privacy, can be effectively protected through an ABE encryption algorithm. With the system and method of the invention adopted, data loss caused by the single-point failures can be avoided, system maintenance cost can be decreased, and a condition that the diagnosis records of the patients are falsified during medical disputes can be avoided.

Description

technical field [0001] The invention relates to the technical field of cyberspace security, in particular to a distributed management system for medical electronic medical records based on block chain technology and a construction method thereof. Background technique [0002] In recent years, blockchain (Blockchain) technology has become more and more well-known to the public. Blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed non-tamperable and unforgeable distributed ledger. Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and utilizes intelligence composed of automated script codes. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. It has the cha...

Problems solved by technology

[0006] The main purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a distributed management system for medical electronic medical records based on blockchain, which writes the doctor's diagnosis process and the process of publishing medical records into the block in the form of smart contracts In the chain layer platform, the four properties of decentralization, security and stability, non-tamperability, and openness and transparency of the blockchain are used to solve the problem that the traditional medical record management system that relies on centralized servers is easy to be illegally tampered with, cannot be traced back to responsibility, and has a single point of failure. Problems such as closed systems between different hospitals
