The Evolution of Intelligent Digital Profiling: A Multi-Sectoral Synthesis of Explainable Artificial Intelligence and Federated Learning Frameworks

Abstract

Digital profiling has evolved into a cornerstone of computational intelligence, enabling the synthesis of complex user representations through the systematic analysis of multi-dimensional digital interactions. This study provides a comprehensive investigation into the conceptual and architectural frameworks of digital profiling, delineating its evolution across various strategic sectors. Utilizing a thematic synthesis methodology, we systematically analyzed 197 high-impact articles published between 2011 and 2025. Our findings categorize digital profiling into six fundamental computational stages: objective definition, multi-source data acquisition, feature selection, similarity modeling, representation synthesis, and iterative monitoring. While the analysis underscores the increasing deployment of profiling in finance, security, and healthcare, it reveals critical systemic risks, including algorithmic bias and privacy vulnerabilities. We propose a strategic transition toward "Privacy-by-Design" architectures, highlighting the integration of Federated Learning and Explainable Artificial Intelligence (XAI) as essential mechanisms for aligning profiling systems with global regulatory standards (e.g., GDPR). This research contributes a robust theoretical roadmap for developing transparent, accountable, and ethically-aligned intelligent systems, bridging the gap between technical efficiency and user-centric rights.
