Abstract

The PHR is defined as the Public Health Record, this PHR enables the patients to manage their own medical records in the centralized way, and (PHR) emerged as a patient-centric model helps in the health information exchange. With the emergence of cloud computing PHR records are stored into the cloud, it reduces the operational cost. By storing the PHRs in the cloud, the patients lose the physical control to their personal health data, so that which makes it necessary for each patient to encrypt her PHR data before uploading to the cloud servers, in the encryption it is challenging to achieve fine grained access control to the PHR record in a scalable and efficient way, hear each patient, their PHR data should be encrypted so that it is scalable with the numbers of users. also there are multiple owners(patients) in a PHR system And all the owner would encrypt her PHR files using a different cryptographic keys, so it is important to reduce the key distribution, To enable the fine grained and scalable access control for the PHRs hear (AES) .Advanced encryption standard encryption algorithm is used
