Abstract: Cloud computing is becoming an emerging paradigm to tenuously store and Share the data for users. A personal health record (PHR) could be a health record during which the patient keeps health data and other information associated with the patient’s care. There is a great challenge of privacy and confidentiality once patient shares their records of the commercial cloud servers, that results in less secure. In view of the above, this paper proposes a technique which combines attribute based access control model with an expansion of ciphertext-policy attribute-set-based encryption (ASBE) and Hierarchical Attribute-based Encryption allows to store the sanitized data securely in the cloud system and also the original data may be retrieved from the sanitized data with the help of the key provided by the data owner. The experimentation is carried out on the data sets and it provides superior performance efficient and accurate results. PHR system categorizes the users to multi security domains so as to scale back key management quality.
