Secure Sharing and Access Control of Personal Health Record in cloud Computing

Abstract

Cloud computing is one of the most advanced technology in recent years. Since this new computing technology requires users to entrust their data to cloud providers.Personal health record (PHR) is an patient-centric model of health information exchange in which the information are outsourced to be stored at the third party server, called as cloud providers, such that security and privacy of the outsourced data should be preserved.Here the user type of each user is organized in a hierarchical manner and it represents the hierarchical structure of the users. The patient details are encrypted using Hierarchical Attribute Set Based Encryption technique. Role of one user is encrypted to another user such that scalability, access control and efficient user revocation is achieved and also it proves the security of HASBE based on security of the Cipher text-Policy Attribute-Based Encryption (CP-ABE) scheme and analyse its performance and computational complexity.
