Advanced AI Algorithms for Fraud Detection: Enhancing Security and Reducing False Positives in Financial Transactions

Financial fraud detection has traditionally depended on rule-based systems, which have fixed thresholds that need laborious manual tweaking and are prone to delayed detection and high false positives. Such inflexible solutions lack more thorough analysis, are ineffective, leave customers wanting more, and cannot keep up with changing fraud tactics. Using machine learning (ML), deep learning (DL), and anomaly detection, the AI-based system has been proposed to make decisions in real-time while dynamically learning fraud trends and reducing false positives. In comparison with traditional techniques, the proposed system achieves a 35% reduced false positive rate (FPR) and a 28% higher detection rate through the use of supervised, unsupervised, and semi-supervised learning. Additionally, it exceeds the latest technology in recall for some fraud types by up to 27%, including phishing, synthetic identity, and card-not-present frauds. The precision and adaptability of the proposed system, however, provide improved security and increased efficiency with a higher latency, encouraging belief in digital financial systems.
