Medical certificate credible issuing and verifying system and method based on blockchain

Abstract

The invention discloses a medical certificate credible issuing and verification system and method based on a blockchain, and the system comprises a node management module which is used for the building and maintenance of a medical conjoined blockchain network architecture, including the initialization and dynamic supervision of a member organization structure in a network, registration of medicalcertificate issuing institution nodes, creation of member services, and deployment of network function components according to function requirements; an identity authentication module which is used for issuing medical certificates of medical staff and auditing and filing identities of certificate inspectors; and a query module which is used for carrying out authorization examination on the certificate query application of the examiner and providing a certificate examination service of an application access control mechanism at the same time. According to the system, firstly, credibility of themedical certificate content and the issuing process thereof is realized; secondly, bidirectional verification and authorized access in the certificate checking process are realized, and the privacy security of system participation users is guaranteed; and finally, realizing a support framework for transaction processing right control between internal entities of the medical alliance and member institutions of the medical alliance.

Description

technical field [0001] The invention relates to the technical fields of computer, communication and information security, in particular to a system and method for credible issuance and verification of medical certificates based on blockchain. Background technique [0002] As a common form of information service identification, electronic certificates have been widely used in various online web services and government affairs systems. On the one hand, it can avoid the risk of loss and damage of paper certification materials due to improper storage, and on the other hand, it can simplify the government affairs process of enterprises and people. According to the relevant laws and regulations of our country, electronic licenses and current licenses (including relevant industry certification materials, business licenses, permits, etc.) have the same legal effect, and there are many examples of information services where the two are used in parallel in reality. [0003] As a key ...

AI Technical Summary

Problems solved by technology

However, my country is still in the initial stage of fully realizing online medical license processing information services, and faces many unresolved problems: First, there is currently a lack of general electronic license specifications for the medical industry in China, including license information item specifications and issuance / verification protocols In terms of standardization, common certificate standards such as X.509 are not closely integrated with the industry background, and the usability is low; secondly, due to the delay in maintaining the online system by government officials, the efficiency is low, and it is difficult to achieve continuous verification of electronic medical certificates. Third, medical certificates are stored and managed in a centralized manner by the issuing agency, which cannot guarantee the security of electronic certificates; finally, there is a lack of a security sharing mechanism to achieve fine-grained access control of certificates, although the current implementation plan is better than paper certificates. Government affairs are more convenient, but most of the privacy of medical staff cannot be guaranteed
