The Healthcare system is the mobile application that stores the large amount of private data of a patient’s or users. Since the collected Patient Health Information (PHI) is private information of patients and plays a critical role in medical diagnosis and treatment. It is essential to strictly limit the access of these data to authorized users only in order to ensure the security of these data and preserve the patients’ privacy. However, the security and privacy protection of the stored data is a major unsolved issue. So, the proposed system provides the security for that users data. The mobile healthcare applications provide easy access to medical care information anytime and anywhere. Recently health is important issue in our daily life. We must have to take care of our health. But this is not possible every time, sometimes because of busy schedule we can’t take care of our health. So, I proposed to build an application of mobile healthcare System using cloud. The system provides a disease oriented information. Main features of this health care system is to provide medical camp with their location, disease oriented information, primary solution to particular disease and hospital locations. The system also provides privacy. This system or application is most useful in emergency cases. With the help of this system patients can check specialization of doctor and according to he/she can take the appointment with that particular doctor. Patients or user can also check for medical camps and then he/she can also register to that camp and take the appointment.
