Balancing National Security and Individual Rights: A Comparative Study of Data Privacy Laws

This dissertation analyzes the legal, political, and technological conflicts between national security requirements and the safeguarding of individual data privacy in five jurisdictions: the European Union, the United States, the United Kingdom, China, and India. This study employs doctrinal analysis, case studies, and comparative institutional evaluation to assess how legal frameworks balance state security functions (surveillance, law enforcement, and intelligence) against privacy rights (including permission, data minimization, access, and redress). The research delineates prevalent design patterns and variations, contextualizes them within the constitutional and political frameworks of each jurisdiction, and presents a series of normative and practical proposals for legal reform and governance. The primary contribution is a calibrated framework-the Security-Privacy Balancing Matrix (SPBM)-designed for policymakers and scholars to evaluate the appropriateness and accountability of data-access methods employed for national security purposes.
