摘要：Personal Health Record (PHR) is maintained in the centralized server to maintain the patient’s personal and diagnosis information. The patient records should be maintained with high privacy and security. The security schemes are used to protect the personal data from public access. Patient data can be accessed by many different people. Each authority is assigned with access permission for a particular set of attributes. The access control and privacy management is a complex task in the patient health record management process. Cloud computing is a colloquial expression used to describe a variety of different types of computing concepts that involve a large number of computers that are connected through a realtime communication network. It is a synonym for distributed computing over a network and means the ability to run a program on many connected computers at the same time. Data owners update the personal data into third party cloud data centers. In this paper, we propose a novel patientcentric framework and a suite of data access mechanisms to control PHRs stored in semitrusted servers. To achieve finegrained and scalable data access control for PHRs, we leverage Attribute Based Encryption (ABE) techniques to encrypt each patient’s PHR file. Multiple data owners can access the same data values. The proposed scheme could be extended to Multi Authority Attribute Based Encryption (MAABE) for multiple authority based access control mechanism.
