Cloud computing has brought significant benefits to healthcare systems, especially when it comes to improving data access and storage efficiency. However, it also raises major concerns around privacy and security, particularly for Electronic Health Records (EHRs). In this paper, we propose a new framework designed to protect EHRs in cloud environments. The framework uses a combination of symmetric and asymmetric encryption techniques to ensure that data stays private during both storage and transmission. It also includes advanced access control measures that regulate who can access the data based on established policies. Our tests show that the framework successfully reduces the risk of unauthorized access while keeping system performance intact. These results highlight the importance of using strong privacy protections to safeguard sensitive health data in cloud-based healthcare applications. This research builds on Dutta et al.’s (2023) work, which explored hybrid encryption techniques to improve the security of health data in the cloud.
