This document summarizes a research paper that proposes a novel framework for scalable and secure sharing of personal health records in cloud computing using attribute-based encryption. The framework aims to address issues like privacy exposure, scalability in key management, flexible access control and efficient user revocation. It leverages attribute-based encryption techniques to encrypt each patient's health records and divides users into multiple security domains to reduce complexity. The scheme guarantees patient privacy, enables dynamic modification of policies, and supports efficient revocation and emergency access.
