Abstract: The use of cloud-based electronic health records (EHRs) has led to improvements in healthcare delivery, but concerns about data privacy and security remain. Healthcare Security as a Service (HSaaS) is a promising solution to address these concerns, and integrating HSaaS with blockchain technology can further enhance the security and privacy of cloud-based EHRs. Intelligent healthcare provides an opportunity to improve the security and accessibility of cloud-based EHRs, and this research aims to explore the potential of HSaaS with blockchain integration for intelligent healthcare. The research will investigate the current security challenges in cloud-based EHRs, evaluate the potential of HSaaS for addressing these challenges, and develop a proof-of-concept prototype that integrates HSaaS with blockchain technology into a cloud-based EHR system. The performance and security of the proposed solution will be evaluated, and the benefits and limitations of using HSaaS with blockchain integration for securing cloud-based EHRs will be analysed. This research aims to provide a more secure and trustworthy environment for cloud-based EHRs, contributing to improving healthcare delivery.
