Scalable and Secure Sharing of Personal Health Records in centralized Database Using Attribute-based encryption

Abstract: Personal health record (PHR) is used to maintain patient�s personal and diagnosis information, and is stored at a thirdparty i.e., cloud providers. The main concern is about diagnosis information. Due to Personal health record (PHR) patient manage and create his its own health record and the patient�s could actually control the sharing maintain with high security and high privacy. Personal health record (PHR) protect and secure the patient�s personal health information (PHI) from unauthorized users. The patient�s have control over access to their own PHR. To achieve high security of personal health records, we use the attribute based encryption technique to encrypt the all patient�s data before outsourcing or before access from unauthorized user. We prestige attribute-based encryption (ABE) practices to attain scalable and fine grained data access control for personal health records to encrypt each patient�s PHR file. Data owner update the personal health data into third party cloud data centers. Multiple data owners can access the same type of patient�s data from cloud. The Personal health record (PHR) is a high degree of patient�s privacy is guaranteed.
