Secure access control for cloud-based tele medical system

Recent technological advancements are offering users new and easier ways to access healthcare services. With the advent of high-speed networks, low cost storage, inexpensive telecommunication systems, patient monitoring systems, cloud computing, telecare medical information system (TMIS) is becoming a reality. Due to the advantage of tele-healthcare medical system, we are reaching directly to the patients' home over internet or mobile networks and data is stored as electronic medical records (EMR). The major challenge here is ensuring secure access of communication data by patients and doctors, for this we need a secure and efficient way of user access control, so that attacker cannot impersonate the user or medical server. The confidentiality, integrity and availability need to be ensured. Also, the authentication process should be user friendly so that even elderly patients can use it easily. Medical data includes medical images which might be tampered by intruders. Our aim is to overcome the limitation of present market scenario and provide the efficient way of communication between user and doctor with help of cloud-based system.
