In the recent years, storage of the data and its security is the big issue in any organization. Cloud Computing is an emerging paradigm which changes the way in which the information is managed. End users can access Cloud services without any expert knowledge. Cloud computing technology provides a huge infrastructure and offers large scale services to the Healthcare industry. Indeed, there are several security challenges such as losing physical control, multitenancy and privacy breach. This project is focusing to develop a website for Healthcare organization. The components are Admin (to start the process), Owner (the doctor, who is going to upload the data on cloud), and Users (Patients, Radiologist, Pathologist etc). It will be a centralized system for all the three components. Radiologist and pathologist will have limited access and the patient will have lifetime access to the data available on cloud. There is no need for patients to carry the prescription and maintain the file as the data is stored on the cloud. The patients can see if the update is done by a doctor and other users. In the proposed scheme, Elliptic curve cryptography (ECC) is used to generate digital signature. Also Attribute based encryption (ABE) is used for encryption and decryption.
