Data Privacy and Institutional Responsibility in the Use of AI Surveillance Technologies in Public Spaces: A Comparative Legal Analysis

Project Abstract

This study undertakes a comparative legal analysis of data privacy and institutional responsibility in the deployment of artificial intelligence surveillance technologies in public spaces, examining how different jurisdictions balance security imperatives with individual rights, due process, and governance mechanisms. By integrating doctrinal legal analysis with comparative methodology, the research evaluates statutory frameworks, regulatory guidance, and case law across selected civil law and common law systems to identify convergences and divergences in privacy protections, data minimization principles, purpose limitation, transparency obligations, consent regimes, and the rights of access, correction, and deletion. The analysis places particular emphasis on the role of public institutions, law enforcement agencies, and private contractors in data processing, retention, analytics, and sharing, highlighting accountability mechanisms, risk assessment requirements, and oversight structures such as independent data protection authorities and judicial remedies. A key objective is to map how governance architectures address AI-specific challenges, including automated decision-making, facial recognition, predictive policing, and real-time surveillance, as well as the interoperability of cross-border data transfers and the exposure of vulnerable groups to discriminatory outcomes. The study also investigates the adequacy and effectiveness of privacy-by-design and security-by-design approaches, scrutinizing technical and organizational controls, algorithmic transparency, explainability, and redress pathways for harms arising from surveillance practices. Through stakeholder interviews, doctrinal synthesis, and policy analysis, the research assesses the proportionality and necessity tests applied to intrusive surveillance interventions, the accessibility of regulatory exemptions for public safety and national security, and the implications of evolving international norms and guidelines on data ethics and human rights. The comparative lens reveals best practices for enhancing institutional accountability, including robust impact assessments, public scrutiny mechanisms, sunset clauses, and explicit limitations on data retention and third-party data sharing. It further identifies gaps in enforcement capacity, data subject empowerment, and remedies for privacy violations in the context of AI-driven public surveillance. The ultimate aim is to provide a coherent framework that informs policymakers, regulators, and practitioners on balancing legitimate public interest objectives with fundamental privacy rights, while offering actionable recommendations for harmonizing legal regimes, strengthening oversight, and embedding continuous accountability in the deployment of AI surveillance technologies in public spaces. Policy implications are discussed for design-of-law, constitutional safeguards, data protection statutes, and sector-specific regulations, with attention to potential implications for democratic legitimacy, civil liberties, and public trust in law enforcement and municipal governance. The study concludes with a synthesis of findings and proposed pathways for reform that enhances proportionality, transparency, and accountability in AI-enabled public surveillance across diverse national contexts.
