於現今醫療資訊高度數位化及其流通與再利用日益普遍，惟現行法制對於回溯性醫療資訊的再利用缺乏完整規範，導致個人隱私權保障不足。研究目的在於從資訊治理視角出發，重新思考我國醫療資訊規範之法政策結構，並試圖建構一套兼顧資訊流通與隱私保護的規範體系。方法上採文獻分析與比較法途徑，聚焦於歐美與日本之規範典範，並以我國憲法中未列舉基本權的隱私權為核心，連結資訊主體的主觀與客觀保障結構，評析其制度化條件與立法趨勢。全論文架構分為六章，依序鋪陳我國醫療資訊流通現況與問題、隱私權保障架構、比較法制借鏡、資訊治理理論與歐盟新制，以及具體修法建議，最終建議我國應朝向以資訊治理為基礎之新制度設計發展。

In the context of increasingly digitized medical information and its growing circulation and secondary use, the current legal framework in Taiwan lacks comprehensive regulation regarding the retrospective use of medical data, resulting in insufficient protection of individual privacy rights. This study aims to reconsider the legal and policy structure governing medical information from the perspective of information governance and to propose a regulatory framework that balances data circulation with privacy protection. Methodologically, the research adopts literature analysis and a comparative legal approach, focusing on the regulatory models of Europe, the United States, and Japan. It centers on the unenumerated constitutional right to privacy in Taiwan and links the subjective and objective dimensions of protection for data subjects to assess the institutional conditions and legislative trends. The thesis is structured into six chapters, which sequentially explore the current landscape and issues of medical data governance in Taiwan, the framework of privacy protection, insights from comparative law, information governance theory and EU developments, and concludes with concrete legislative proposals. Ultimately, the study advocates for a new institutional design based on information governance.
