This chapter explores how Artificial Intelligence (AI) is revolutionizing Fraud Detection and Prevention within finance and banking. Traditional methods fall short against modern fraud schemes, driving the adoption of AI. AI-powered solutions, including Machine Learning, Natural Language Processing (NLP), and Anomaly Detection, scrutinize transactional data to identify fraudulent patterns, enhancing accuracy. Real-world applications encompass transaction monitoring, identity verification, and fraud prediction. Emphasizing Explainable AI, this chapter delves into the transparency of AI-driven decisions, crucial for addressing challenges like data privacy and algorithmic biases. Continuous innovation is essential to outpace fraudsters. Ultimately, leveraging AI promises to safeguard assets and bolster trust in financial systems.
