This paper presents a comparative study of health data governance legal frameworks in the context of digital health technologies between the European Union (EU) and China, focusing on the assisted living sector. As healthcare systems undergo digital transformation, the widespread use of advanced ICT has led to extensive health data collection, raising privacy concerns. The paper examines the legal responses in the EU and China, identifying gaps and contradictions in their regulatory approaches, and provides recommendations on how existing laws should evolve to address these challenges effectively.
