This document discusses a proposed scheme for securely accessing personal health records (PHRs) stored in cloud computing. It begins with background on the benefits of storing PHRs digitally in the cloud but also the privacy and security risks. It then outlines challenges in allowing dynamic access to PHRs by different user groups like hospitals, insurers, and third parties. The proposed scheme aims to address these challenges by supporting secure, encrypted access for dynamic groups while enabling easy user revocation without distributing new keys. It discusses related work in access control and key management for outsourced data and presents the design of the proposed model featuring PHR owners and group managers for different organizations that access records in the cloud.
