AI Governance Frameworks for Privacy-Preserving Intelligent Systems: Integrating Trust, Compliance, and Secure Data Architectures

Counts differ because each database indexes a different set of publications. We treat OpenAlex as the canonical count; Google Scholar is not shown (no API, and crawling it violates its ToS).

Artificial intelligence (AI) systems now process personal and organizational data at a scale that outpaces the legal and technical mechanisms designed to protect it. This article examines how governance frameworks can be structured to reconcile three objectives that are often treated separately: user trust, regulatory compliance, and secure data architecture. Drawing on privacy-enhancing technologies such as differential privacy, federated learning, homomorphic encryption, and secure multi-party computation, together with regulatory instruments including the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and the European Union Artificial Intelligence Act (EU AI Act), we propose an integrated governance model called the Trust–Compliance–Architecture (TCA) framework. The framework links technical controls to accountability mechanisms and maps them onto a lifecycle model spanning data collection, model training, deployment, and audit. We review over one hundred sources spanning computer science, law, and information systems, and we illustrate the framework with three applied scenarios spanning healthcare analytics, financial fraud detection, and public-sector/smart-city analytics. The analysis suggests that governance frameworks succeed when privacy-preserving technologies are embedded into system architecture from the outset rather than added afterward, when compliance obligations are translated into measurable technical requirements, and when trust is treated as an emergent property of verifiable behavior rather than a matter of disclosure alone. The article closes with a discussion of open problems, including the auditability of federated systems, the tension between explainability and privacy, and the absence of harmonized cross-border standards.
