Design and implementation of medical dispute governance based on blockchain

Abstract

Electronic medical record is the core component of hospital information system, and it is also an important evidence in solving social security and governance such as medical disputes, medical insurance cash and fraud. The most advanced digital certificates and other technologies have effectively solved a series of important security issues such as “identity camouflage” and “man-in-the-middle attacks” and have been granted certain legal effects. However, due to their dependence on trusted third-party organizations, there are facts. Technical loopholes and serious trust crises. Blockchain technology is considered to be the best solution for current data security due to its decentralized distributed storage, non-tamperable, consensus computing and other characteristics, and has received widespread attention. Based on the alliance blockchain architecture, the research project supported by this paper selects the health service and management organization of Nanshan District of Shenzhen as the social programming practice scenario; builds the alliance blockchain network based on Fabric super account, writes and deploys intelligent contracts, and collects the core of electronic medical records. The data item (desensitization) generates a HASH digest, and stores the HASH digest on the alliance blockchain network; the user can select the network node to download the corresponding HASH digest, and perform the two-way comparison to complete the electronic medical record security credit, thereby realizing Key governance of medical disputes. The experimental results show that the system can effectively complete the protection and acceptance of electronic medical records, and has a good social security and governance application prospects.
