Huge volume of continuity generated data or record sharing at will have constrained most of the physicians to approve EHR (Electronic Health Record) for record-keeping of patients. It also makes convenient to the other stake holders of healthcare ecosystem such as nurses, specialists and patient. Due to lower costs and scalability of application, the cloud is becoming the infrastructure for most of the EHR but without comprising the privacy of data. In this paper we have proposed Secure Access Control Mechanism for Ensuring Privacy of EHR in Public Cloud In this case, cloud computing helps users to effectively manage health information, increase storage capacity, and secure access to information through access control systems. Access control to protect patient data in health information systems is a primary security barrier. Access control ensures that content is available to content owners. With the help of an access control mechanism supported by authentication, patient privacy can be achieved in health information systems.
