In recent years, the management and storage of electronic medical records (EMRs) within mobile cloud environments have evolved rapidly, transforming the way healthcare data is exchanged. The integration of mobile devices with cloud computing has enabled more seamless communication between patients and healthcare providers, improving accessibility and efficiency. This technological shift offers numerous advantages, including cost reduction, enhanced flexibility, and broader adoption of EMRs across healthcare systems. However, alongside these benefits come significant challenges, particularly regarding data privacy and security. Protecting sensitive EMRs within mobile cloud platforms is a critical issue, as breaches or unauthorized access could have severe consequences. To address these challenges, this paper explores the potential of blockchain technology as a robust solution for enhancing data protection in cloud-based healthcare systems. The proposed framework integrates an optimized Blowfish encryption algorithm to ensure data authenticity and integrity. Furthermore, it introduces an innovative key generation mechanism Elephant Herding Optimization (EHO), which strengthens cryptographic resilience and fortifies the security framework. By combining these cutting-edge techniques, the approach aims to establish a secure, reliable, and confidential ecosystem tailored to the evolving landscape of mobile eHealth.

摘要

In recent years, the management and storage of electronic medical records (EMRs) within mobile cloud environments have evolved rapidly, transforming the way healthcare data is exchanged. The integration of mobile devices with cloud computing has enabled more seamless communication between patients and healthcare providers, improving accessibility and efficiency. This technological shift offers numerous advantages, including cost reduction, enhanced flexibility, and broader adoption of EMRs across healthcare systems. However, alongside these benefits come significant challenges, particularly regarding data privacy and security. Protecting sensitive EMRs within mobile cloud platforms is a critical issue, as breaches or unauthorized access could have severe consequences. To address these challenges, this paper explores the potential of blockchain technology as a robust solution for enhancing data protection in cloud-based healthcare systems. The proposed framework integrates an optimized Blowfish encryption algorithm to ensure data authenticity and integrity. Furthermore, it introduces an innovative key generation mechanism Elephant Herding Optimization (EHO), which strengthens cryptographic resilience and fortifies the security framework. By combining these cutting-edge techniques, the approach aims to establish a secure, reliable, and confidential ecosystem tailored to the evolving landscape of mobile eHealth.
