Secure Patient Data Sharing in Mobile Ubiquitous Environments

Mobile and ubiquitous computing have positively transformed healthcare by allowing constant access to a patient's data through various devices and platforms. While this has enhanced the quality and efficiency of healthcare services, concerns regarding the protection of sensitive information, such as data security and patient privacy, still pose serious challenges. With rapid and distributed systems, safeguarding sensitive health information regarding confidentiality, integrity, and access control remains challenging. This paper addresses the problem of secure patient data sharing in mobile ubiquitous environments by examining the risks of unauthorized access, data modification, and information exposure. It examines existing protective measures employed in healthcare institutions that utilize encryption and authentication mechanisms alongside role-based access control. Subsequently, this paper proposes a comprehensive security model for the healthcare sphere that uses sophisticated encryption and contextual access control. Selected case studies illustrate the impact of implemented solutions and their subsequent successes and failures on healthcare providers and patients. The paper also presents strategic recommendations from interdisciplinary sources to reinforce the security framework for mobile health applications. Along with analyzing the legal and ethical aspects, its purpose is to demonstrate the importance of safeguarding sensitive information and adhering to data privacy regulations. This research emphasizes the collaboration between the medical field, Information Technology specialists, and lawmakers to create effective strategies for managing patient confidentiality. Furthermore, the security of mobile health systems must be enhanced to maintain patient trust and advance the field of medicine.
