Balancing Accessibility and Confidentiality: Advanced Encryption Techniques for Health Records

Abstract

In the modern era of digital health systems, maintaining a delicate
equilibrium between accessibility and confidentiality of electronic health
records (EHRs) is paramount. This paper investigates the use of advanced
encryption techniques to secure health records while ensuring their timely
accessibility to authorized healthcare professionals. We review the
evolution of encryption in healthcare, assess contemporary cryptographic
methodologies, and propose a hybrid framework tailored to health
information systems. The research evaluates performance metrics such as
encryption time, decryption time, data size overhead, and security levels,
emphasizing the trade-offs between data usability and data protection.
Furthermore, this study includes real-world use cases, a detailed risk
assessment model, and practical guidelines for implementing encryption
strategies in diverse healthcare environments.
