Review on E-Health Privacy and Security through ECC, SHA-256, and Multi-Authority Approaches

Abstract

The rapid digitization of healthcare services has led to the proliferation of electronic health (E-Health) systems, providing convenience and improved patient care. However, the increasing use of E-Health platforms also raises concerns about the privacy and security of sensitive medical information. This review paper explores the challenges surrounding E-Health privacy and security and presents a comprehensive approach to addressing these concerns through the implementation of Elliptic Curve Cryptography (ECC), Secure Hash Algorithm 256 (SHA-256), and multi-authority schemes. The synergistic application of these cryptographic techniques not only fortifies the protection of patient data but also establishes a robust framework for secure data sharing and management in E-Health systems.
