Next-Gen Banking Security: Real-Time Fraud Mitigation through Intelligent AI and Event-Driven Architectures.

Fraud remains one of the most critical challenges in the financial sector, driven by increasing digital transactions, evolving cyber threats, and sophisticated criminal patterns. Traditional rule based systems often fail to detect emerging fraud behaviors due to static thresholds and limited adaptability. Modern fraud detection approaches leverage machine learning, real time data analytics, behavioral profiling, and anomaly detection to identify suspicious activities with higher accuracy. This paper examines current fraud trends across banking, payment systems, and digital finance, and evaluates advanced detection techniques including supervised learning, unsupervised clustering, neural networks, graph based analysis, and AI driven risk scoring. The study highlights the benefits of real time monitoring, feature engineering, big data pipelines, and model explainability to support regulatory compliance and operational trust. Challenges such as false positives, data privacy, scalability, and integration into legacy systems are addressed, along with future directions in federated learning, adaptive models, and multi channel transaction intelligence. The findings demonstrate that AI powered fraud detection significantly improves prevention capabilities, reduces financial losses, and strengthens customer security across the financial ecosystem.
