Electronic health record authorization sharing and management system based on medical blockchain

Abstract

The invention relates to an electronic health record authorization sharing and management system based on a medical blockchain. The system comprises a user side, a medical information management system, a hybrid chain up-chain and down-chain medical information database and an identity authentication system, wherein the user side comprises a patient side and a doctor side which are respectively used for carrying out electronic health record related operations; the medical information management system is a platform for a user side to carry out related operations and is used for sending the related operations to the hybrid chain up-link and down-link medical information database. The medical information management system is also an implementation platform of the distributed encryption and decryption module, cooperates with the identity authentication system and is used for encrypting and decrypting the electronic health record of the patient and verifying the identity authenticity of the user side; the hybrid chain up-link and down-link medical information database is composed of a block chain network and a cloud medical database; the identity authentication system is composed of anidentity authentication center and a certificate issuing center. The system is favorable for safely and quickly authorizing and sharing the electronic health record, and the privacy, safety and reliability of the electronic health record are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to an electronic health file authorization sharing and management system based on medical block chains. Background technique [0002] In the existing technology, the exchange of health records and physical examination reports between patients is mainly through the hospital HIS system. The patient information is closed in the hospital's own HIS system. It is impossible to authorize and share electronic health records between HIS systems. In addition, electronic health records are mostly stored in the hospital's local server or cloud database, and the distribution of health records is managed through the HIS system. The data control right is solely controlled by the hospital. It is difficult to guarantee the privacy and security of patients' health records, and there is a single point glitch problem. Contents of the invention [0003] The purpose of the present in...
