Abstract	The rapid expansion of digital banking networks has significantly increased the complexity and frequency of financial fraud activities. As banking operations continue to migrate toward digital platforms, financial institutions face growing challenges related to unauthorized transactions, identity theft, payment fraud, account manipulation, and sophisticated cyber threats. Traditional fraud detection approaches based on predefined rules and manual investigation processes often demonstrate limitations in identifying emerging and adaptive fraud patterns. Artificial Intelligence (AI)-based fraud detection systems have emerged as advanced security mechanisms capable of analysing large-scale financial data, recognizing complex behavioural patterns, and supporting real-time fraud prevention. This conceptual research article examines the role of artificial intelligence in strengthening fraud detection capabilities within modern banking networks. The study explores the contribution of machine learning algorithms, deep learning models, predictive analytics, behavioural analysis, and intelligent automation in identifying suspicious financial activities. It further analyses how AI-driven security frameworks improve detection accuracy, operational efficiency, and risk management practices in digital banking environments. The research highlights that AI-based fraud detection systems provide significant advantages by enabling continuous transaction monitoring, adaptive learning, and automated risk assessment. However, successful implementation requires addressing important challenges including data privacy concerns, algorithmic transparency, cybersecurity risks, regulatory compliance, and technological infrastructure requirements. The study emphasizes that effective fraud prevention depends on the integration of advanced AI technologies with responsible governance frameworks, human expertise, and secure banking architectures. The findings contribute to understanding the strategic importance of AI-driven security solutions in modern banking networks and provide insights into future developments of intelligent fraud detection ecosystems.
