Cloud computing is delivery of computing resources such as processing power, storage and networking as a service to users. Data stored on the cloud can be accessed by cloud service provider if stored in clear text, so data on public clouds should be encrypted and stored to avoid unauthorized access. Cloud users storing his PHR on the cloud can be targeted and misused by advertising agencies and doctors for in advent actions. For securing user PHR stored on public cloud we have proposed a system which uses homomorphic key encryption. Our proposed system provides protection, integrity, privacy preservation, role based access control, homomorphic key encryption for user PHR stored on public cloud. In role based access control we have divided our system into multiple security domains. Each security domain provides access to authorized users based on roles. In case of emergency break glass access is provided to users from emergency department. Using the solutions quoted above we provide highly secure system for outsourcing and sharing users PHR on public cloud.
