Scalable and Secure Sharing of Personal Health Records in Cloud Computing Using Attribute Based Encryption
Personal health record (PHR) is patient centric model in that patient's health information can share with anyone it will be store in third part, it will be work as cloud. Hence there is main concern of security of private health information as it was stored at third party server and to unauthorized parties. In these proposed method before outsourcing the data give the assurance to patients they having the authority to access own PHR. Till issue such as risk of Health information exposure, easily accessibility, Key Management, efficiency user revocation. In this paper, we define patient centric architecture and access control for achieve the information of PHR which is stored in cloud server. We can encrypt patient's PHR File by using Attribute based Encryption and easy to access control on PHR File. As compare to previous work we secure data outsourcing. In these studies we focus on multiple data owner scenario for the avoid complexity for the user and owner and divided users in different security domain. We can focus also access policies dynamic modification, support to on demand user or attribute revocation, access speedily in emergency situation. In our proposed method scalability, efficiency and securities.
