An Enhanced Scheme for PHR on Cloud Servers Using CP-ABE

Abstract

In today’s digital world, cloud computing gives the illimitable possibilities. Personal Health Record (PHR) enables patients to store, share, and access personal health data in centralized way such that it can be accessible from anywhere and anytime. Indeed, coalescing of PHR with cloud gives incipient horizons for medical fields to be digitalized in centralized storage but it comes with major concern i.e. security. There are many researchers are work in securing PHR which stored in cloud utilizing gave approaches but it’s not enough to secure it. So there is desideratum for incipient technology as Attribute Based Encryption that secure PHR with providing many functionalities such as revocation of utilizer, delegation of other utilizer access, accountability, probing over encrypted files, multi-authority and many more.
