Electronic medical record sharing system with privacy protection function based on alliance chain and application method

Abstract

The invention discloses a blockchain-based electronic medical record sharing system with a privacy protection function and an application method, and the system comprises a medical management department, a medical institution and a medical service receiver, and achieves the operations of system initialization, registration, electronic medical record sharing and electronic medical record deletion.According to the invention, through a hidden authorization mechanism, the system achieves the privacy protection in the electronic medical record sharing process, and can achieve the electronic medical record sharing under two scenes: electronic medical record sharing among different doctors in the same hospital and electronic medical record sharing among different doctors in different hospitals;in the electronic medical record sharing process, a patient has complete control right on electronic medical records of the patient. In addition, after the electronic medical record exceeds the validity period, the local cloud and the blockchain of each medical institution delete the electronic medical record.

Description

technical field [0001] The invention belongs to electronic medical record sharing technology, in particular to an electronic medical record sharing system and application method with privacy protection based on alliance chain. Background technique [0002] Electronic health records (EHR) are data sets related to patient health status, including medical conditions (diseases, etc.), drug prescriptions, medical images, and personal information (name, age, gender, weight, bill information, etc.). However, the patient's medical information is not considered valid between different hospitals. For example, suppose a patient from a hospital transfer to another hospital Hospital May not be able to fetch patients in hospital The results of the examination, the hospital may also consider hospital The results of the examination have no reference value, so for this patient, it is necessary to go to the hospital Check again. To a large extent, the examination results of two...

Problems solved by technology

[0005] At present, there are some electronic medical record sharing schemes based on blockchain, which guarantee data integrity, confidentiality and access control, but these schemes have some shortcomings: first, the attacker may obtain the patient's private information, for example, the attacker may pass The public transaction information and data on the blockchain can speculate on the user's preference for doctors
