Abstract

Access control stands as the single most critical component of cloud storage architecture for enhancing data security. Traditional techniques for data sharing and access control encounter substantial challenges in the research arena, stemming from concerns such as private data leaks and key abuse. With the advent of cloud computing, healthcare applications now have the capability to exchange patient records, thus leveraging the outsourcing of Electronic Health Records (EHR). Moreover, blockchain technology provides a secure foundation by employing multiple encryption methods to verify users. However, patient privacy may be compromised while utilizing the cloud, notwithstanding its benefits in management.This study focuses on two primary outcomes: enhancing access control in blockchain-based cloud systems and refining procedures for exchanging and retrieving data with a focus on prioritizing user privacy. The primary contribution lies in delineating a framework for managing access and data exchange in the cloud using blockchain technology. A well-established method for sharing data and controlling access based on blockchain technology successfully reduces the impact of a cloud infrastructure's single point of failure. Our design integrates off-chain storage solutions to address blockchain's scalability issues while safeguarding EHR privacy and confidentiality. Additionally, we explore the integration of advanced cryptographic techniques to further fortify data security.The proposed system is meticulously crafted to align with existing healthcare standards and facilitate seamless interoperability between different healthcare providers. We evaluate the performance and security of our blockchain-based framework through a series of experiments and compare it with traditional EHR sharing methods. Our findings demonstrate that our framework significantly enhances the security of EHR sharing without compromising the efficiency of data access.
