Efficient and Confident Sharing of Personal Healthcare Records using Attribute Based Encryption in Cloud Computing

Personal Health Record (PHR) is an emergent patient-centric model of health information exchange and it is stored at cloud. But there have been some confidential concerns such as exposed the personal healthcare information to unauthorized parties. In order to promise the patients authority over methodology to their PHRs, It is guaranteed method to encrypt the PHRs before outsourcing. While PHR service shifted to cloud computing, successful factors can be security, privacy protection and service efficiency. We stimulus the Attribute Based Encryption (ABE) practices to accomplish the scalable and confident data access control over personal health record to encrypt the each patients file. In this paper, we distillate on the multiple data owner consequence and segment the users to minimize the complexity of owners and users. In sensitive case we change the file access policies to access the encrypted files. Thus, the project provides efficient and confident personal health record stored on the cloud for life long use.
