Cloud computing servers provides platform for users to remotely store data and share the data items to everyone. Personal health record (PHR) has emerged as a patient –centric model of health information exchange. Confidentiality of the shared data is the major problem when patients uses the commercial cloud servers because it can be view by everyone., to assure the patient’s control over access to their own medical records; it is a promising method to encrypt the files before outsourcing and give access control to that data. Privacy exposure, scalability in key management, flexible access and efficient user revocation, have remained the most important challenges toward achieving fine-grained, cryptographically enforced data access control In this paper a high degree of patient privacy is guaranteed by exploiting multi-authority ABE. Divide the users in the PHR system into multiple security domains that greatly reduces the key management complexity for owners and users.
