INTRODUCTION Over the past three decades, computer systems are used extensively in medical and healthcare systems. For the documentation, storage, processing, analysis and presentation of patient’s information storage devices and server systems are used in developed countries today. Yet, most healthcare systems are built on the basis that consists of paper medical records, handwritten test results, non-digitized images, handwritten notes and fragmented IT systems. Sharing of information across providers is inefficient and insecure and portability of data is very rare. Doctors and physician depend on the medical staffs for patient’s data, coordinating their care schedules and other administrative systems activities. All these processes are cumbersome and time consuming. So, there are many more challenges in this sort of systems where a large number of records are stored and data requirements are scalable, flexible, easy to create, update, manage and access etc. but security has topmost priority. It is found by a research on Healthcare systems in 2009 in USA that half of $2.2 billion that is used in medical and healthcare systems is wasted. So, for improving Healthcare Information Technology (HIT) a Health Information Technology for Economic and Clinical Health (HITECH) Act has been passed. An amount of $18 billion are included for medical records so that records are kept in a format known as Electronic Medical Record (EMR). Our main focus is the patient’s data collection, storage, access, analysis, and presentation etc. We have suggested the current patient data collection techniques are time consuming, inefficient, laborious for the staffs. It is also obvious that currents technique is violating the real time data access for diagnostics or monitoring the patients. Our proposed solution is based on the concept of “Cloud Computing” a distributed computing system where a pool of virtualized, dynamically-scalable, managed computing power, storage, platforms, and services are delivered. We have proposed a “Health Cloud” model which is based on Cloud Computing and wireless sensor networks (WSN) concept. Electronic apparatus and machines that are attached to the patient’s body containing “Sensor” will send the patient’s data to the cloud. Doctors, physicians and medical staffs access the cloud and use those data for further analysis. The patients themselves can also see their personal information, medication etc. We have also followed the Right Management Technique which ensures when, by whom and how data are accessed, even after it has been distributed through arbitrary communication channels. Right management technique ensures that only authorized users can access the cloud with the unique valid username and password (secret key) and it also ensures the data privacy, security with no intrusion of outsiders in the whole systems. Previously most of the security mechanisms for data are implemented outside the cloud system. Our proposed model security is based on the Attribute Based Encryption (ABE) algorithm that has to be set up within our cloud architecture that will guarantee the security, privacy and confidentiality of the sensed data of the patients. We have also included different access structure policy for different users in the system for the flexibility and dynamicity of the system.
