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 naïve 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.
