Technological advancements have revolutionized healthcare by integrating wireless communication with cloud computing, resulting in the widespread adoption of Electronic Health Records. EHRs have supplanted traditional paper records, providing healthcare providers with ubiquitous access to patient information. This integration enhances both the security and efficiency of healthcare systems, facilitating the secure exchange of vast amounts of real-time data. This project aims to evaluate the efficiency and effectiveness of EHR systems through a comparative analysis of relevant studies. To safeguard patient data from unauthorized access, the project proposes a hybrid cryptographic technique that combines the Advanced Encryption Standard and Elliptic Curve Cryptography. AES uses a symmetric key for both encryption and decryption, which presents a risk if the key is compromised. Conversely, ECC utilizes asymmetric keys, enhancing security with smaller key sizes and making unauthorized access more difficult. By integrating AES and ECC, the proposed hybrid approach leverages the efficiency of AES and the robustness of ECC, addressing the limitations of each method. This hybrid technique bolsters the overall security of EHR systems, ensuring data integrity and patient confidentiality in cloud-based healthcare environments. Implementing this solution enables healthcare organizations to better protect patient data from unauthorized access, thereby providing a more secure and reliable system.
