Electronic medical record sharing method and system based on block chain

Abstract

The invention provides an electronic medical record sharing method and system based on a block chain, wherein the method comprises the following steps: a medical health card generates an asymmetric secret key pair; the first medical institution node performs registration verification on the user by utilizing the asymmetric secret key, and when the verification is passed, a first medical institution node uses the asymmetric secret key to perform registration verification on a user; when the verification is passed, the steps are carried out as follows: when an authorized sharing trigger is received, the first medical institution node performs standardized processing on the electronic medical record, and the encrypted standard electronic medical record is sent to a first front-loaded database; when an authorized use trigger of the user is received, the second medical institution node generates an intelligent contract and the signed intelligent contract is issued to a block chain; a verification node, according to the intelligent contract, triggers the execution as follows: the first medical institution node conducts validity verification on the signed intelligent contract; when the verification is passed, an encrypted standard electronic medical record is exchanged to a second front-loaded database; the second medical institution node decrypts the encrypted standard electronic medical record to obtain a standard electronic medical record. According to the scheme, the sharing process of the electronic medical record can be simplified.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a blockchain-based electronic medical record sharing method and system. Background technique [0002] Smart healthcare has shifted from the pursuit of a single system scale to the integration of operation and management centered on electronic medical records, and has made full use of technologies such as the Internet, mobile Internet, and the Internet of Things to effectively realize the relationship between patients and doctors, medical staff, hospitals, medical institutions and The interaction between medical devices realizes patient-centered business collaboration services in a certain area. However, data exchange between nodes of different medical institutions has encountered many difficulties, especially when it involves patient privacy. In this case, how to effectively realize the safe sharing of electronic medical records across medical institution nodes has beco...
