A Design of Medical Information Sharing Model Based on Blockchain Technology

Abstract

Through the studying of the status quo of medical industry, we find some problems with the sharing of medical data. The medical data in traditional medical institution is stored on severs and its backup database, resulting in lack of communication among medical institutions and ineffective use of medical resources. In order to solve this problem, we propose a medical information sharing model based on blockchain technology. In this model, we build a p2p network to connect different medical institutions and other nodes. Meanwhile, we establish two associated blockchain to store medical data digests and requests. Each node in the p2p network can search the medical information in the distributed medical institutions. In this way, we have integrated medical data between medical institutions and improved the transparency and sharing of medical data. Also, we improve the traditional POW (power of work) algorithm, by using the double-chain structure, we reduce the confirmation time of a block.
