Abstract: Healthcare Informatics (HCI) empowers patient to deal with their own therapeutic records in a digitalized and centralized path. The main aim of this paper is accessing this stored information on cloud by authorized personnel, anywhere, anytime through any device. Healthcare Informatics contains sensitive patient data, clinical history that should to be protected against unauthorized users on cloud. In this study, role-based access control and fine-grained access control were proposed. The results of this study are utilized in the policy enforcement and the access control policies. With the help of cryptographic techniques, the proposed algorithm in this study, provides the higher-level privacy and prevention of cyber-attacks in healthcare informatics. 
Keywords: Access control, Cloud computing, Cyber-attacks, Healthcare informatics.
