Scalable And Secure Sharing Of Personal Health Records In Cloud Computing Using Multi Authority Attribute-Based Encryption

Abstract

Personal Health Record (PHR) is maintained in the centralized server to maintain the patient's personal and PHR services are outsourced to third-party service providers. The main concern is about diagnosis information. The patient records should be whether the patients could actually control the sharing 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 real-time 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. The novel patient-centric framework and a suite of data access mechanisms to control PHRs stored in semi-trusted servers. To achieve fine-grained 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.
