For the medical industry, there are problems such as poor sharing of medical data, tampering, and leakage of private data. In view of these problems, a blockchain-based electronic medical record access control research scheme based on the role-based access control model is proposed in this article. First, the appropriate access control strategy is adopted to solve the leakage problem of the user’s medical privacy information during the access process. Then, the information entropy technology is used to quantify the medical data, so that the medical data can be effectively and maximally utilized. Using the distributed general ledger characteristics of blockchain and its inherent security attributes, data islands can be eliminated, data sharing among medical systems can be promoted, access records can be prevented from being tampered with, and medical research and precise medical treatment can be better supported. Through this research, not only can user’s medical privacy information protection be realized during the service process but also patients can manage their own medical data autonomously, which is beneficial to privacy protection under the medical data sharing.

Electronic Medical Record (EMR) is basically the digital equivalent of paper records, or charts at a clinician’s office. EMR assist and make easier the services rendered by a wide range of medical practitioners such as physicians, nurses, pharmacists and many others, hence, increasing the safety of patients. It's importance in the health sector cannot be overemphasized. The designed framework aims at identifying security challenges in the use and adoption of EMR, to design and implement a framework that will address issues identified in the use and adoption of EMR. This study presented a security framework to improve the security and privacy issues of EMRs by adopting Role Based Access Control and RSA cryptography. Role Based Access Control (RBAC) model was used because of its flexibility to support minimal functionality and its simplistic mode of assigning roles and permissions to users. In conclusion, this research was able to improve the security of EMRs and hence will increase its acceptance by health institutions which will bring about improved health services, especially in developing countries were manual record system are still prominent.
