An EMR Sharing and Privacy Protection Mechanism Based on Medical Consortium Blockchain

Abstract

The sharing of Electronic Medical Record(EMR) plays an important role in improving the quality of medical care, reducing costs and enhancing patient experience. But it also raises issues such as privacy leaks and uncontrollable data dissemination. To address these issues, we propose an EMR sharing mechanism based on the medical consortium blockchain. The hospital joins the medical consortium blockchain as a node, storing and maintaining the EMR data it generates. At the same time, the index of EMR is stored on the medical consortium blockchain for query, call and access control. Before accessing the EMR, the patient's authorization needs to be obtained on the medical consortium blockchain. Compared with the traditional mechanism, this mechanism has certain advantages in privacy protection, access control and data security while implementing EMR sharing.
