                  abstract = {The rapid introduction of artificial intelligence (AI) systems across both public and private sectors has significantly increased the concerns regarding the protection of personal data and the right to privacy. Privacy by Design (PbD) has emerged as a key regulatory and technological mechanism aimed at embedding data protection safeguards within the design and architecture of digital technologies. The objective of this article is to examine the legal and regulatory implications of implementing Privacy by Design (PbD) within AI systems, with particular attention to the challenges created by automated data processing and algorithmic decision-making. The central research problem addressed is whether existing data protection frameworks are sufficiently equipped to ensure effective privacy protection in increasingly complex AI ecosystem. This research adopts a doctrinal and comparative legal methodology, the article analyses key regulatory instruments, including the General Data Protection Regulation (GDPR) and the Nigeria Data Protection Act 2023, alongside relevant academic literature on AI governance and data protection. It evaluates the extent to which Privacy by Design principles are embedded in these frameworks and assesses their practical applicability in AI systems. The findings reveal that while PbD has been formally recognized as a regulatory obligation, its implementation remains constrained by technical limitations, particularly the opacity of machine learning models and the data-intensive nature of AI systems. The article argues that current legal frameworks, though progressive, do not fully address these structural challenges. It argues that while Privacy by Design offers an important mechanism for safeguarding personal data in AI-driven environments, significant legal and technical challenges remain in ensuring its effective implementation. It concludes that strengthening Privacy by Design requires enhanced regulatory clarity, interdisciplinary collaboration, and increased institutional capacity. The article concludes by proposing regulatory and institutional strategies to enhance the integration of Privacy by Design in AI governance frameworks, the adoption of enforceable design-based standards, improved algorithmic transparency mechanisms, and greater international harmonization of AI governance frameworks.},
