Privacy Issues in E-health Systems (Preprint)

BACKGROUND The rise of e-health systems, including electronic health records (EHRs), telemedicine platforms, and mobile health applications, has revolutionized healthcare delivery by improving access, efficiency, and quality of care. However, the increasing reliance on digital platforms has raised significant concerns regarding the privacy and security of personal health information. OBJECTIVE This study aims to provide a thorough examination of the privacy issues associated with e-health systems. It seeks to identify and analyze key privacy risks, evaluate current privacy protection measures, discuss their limitations, and suggest potential areas for future research. METHODS We conducted a comprehensive review of the literature on privacy issues in e-health systems. The review included an analysis of current data protection methods, privacy regulations, informed consent practices, and emerging technologies such as blockchain and privacy-preserving algorithms. We also evaluated recent studies on privacy breaches and their impacts on individuals and healthcare systems. RESULTS Our review identified several critical privacy concerns, including unauthorized data access, data breaches, and inadequate encryption. Current solutions, such as encryption and access controls, have limitations, including insufficient protection and challenges in balancing data utility with privacy. We also observed gaps in compliance with privacy regulations and the need for more robust privacy-preserving technologies. CONCLUSIONS Ensuring the privacy of personal health information in e-health systems is crucial for maintaining public trust and enabling the effective use of digital health technologies. While current measures offer some protection, there is a need for improved privacy solutions and stronger compliance with regulations. Future research should focus on developing advanced privacy-preserving technologies, exploring federated learning models, and addressing ethical concerns related to AI in healthcare. Collaborative efforts among stakeholders are essential for advancing privacy protections and optimizing the benefits of e-health systems.
