Literature Review from the year 2015 in the subject Engineering - Computer Engineering, Marwadi Education Foundation (GTU), course: Master of Computer Engineering, language: English, abstract: In an emerging world of cloud computing gives wide range of functionalities. Personal Health Record (PHR) enables patients to store, share, and access personal health data in a centralized way so that it can be accessible from anywhere and anytime. However combining PHR with cloud gives new horizons for medical fields to be digitalized but it comes with major concerns concerning security. There are many researchers working in securing PHR which stored in cloud using naive approaches but it's not enough to secure it. So there is need for new technology as Attribute Based Encryption that secure PHR with providing many functionalities such as revocation of user, delegation of other user access, accountability, searching over encrypted files, multi-authority and many more. So here we survey on this field of securing PHR on cloud using ABE.
