Abstract

This paper reviews the applications of cross-border medical data sharing in clinical practice, medical research, and public health, synthesizes information from various texts, summarizes its developmental value, challenges, and coping strategies, and discusses its new characteristics and future research trends based on literature. It is found that cross-border medical data sharing significantly promotes global medical progress by accelerating disease research, improving the accuracy of personalized medicine, and optimizing public health emergency responses. However, its development faces three core challenges: security vulnerabilities, legal conflicts, and technical barriers. Future breakthroughs need to rely on technology-legal-governance synergy: combining blockchain with attribute-based encryption to achieve dynamic desensitization and fine-grained access control; using regional agreements to bridge regulatory gaps; and enforcing data standardization through hierarchical interoperability frameworks. Only by building a closed-loop governance system can the balance between data sovereignty and research collaboration needs be achieved, thereby unlocking the global health potential of cross-border sharing.

Keywords: Cross-border medical data sharing; Legal compliance conflict; Privacy-enhancing technology; Hierarchical interoperability.
