The integration of artificial intelligence (AI) and machine learning (ML) into risk management and fraud detection within the financial sector marks a significant evolution in combating financial crimes and improving operational efficiencies. This chapter explores the transformative impact of AI and ML technologies, presenting detailed case studies that illustrate their real-world applications in banking and insurance. Emerging trends and innovations, such as federated learning, quantum computing, and blockchain technology, are explored for their potential to further revolutionize risk management practices. However, the adoption of these advanced technologies also introduces complex challenges and ethical considerations, including concerns about data privacy, the need for regulatory compliance, and the imperative to ethical AI use. The discussion emphasizes the importance of navigating these challenges through robust data protection measures, transparent AI algorithms, and adaptive regulatory frameworks to ensure the responsible and effective use of AI and ML in finance.
