Taiwan's Financial Sector Strengthens Anti-Fraud Efforts Through Cross-Domain Collaboration, Enhancing AI Model Capabilities

(CNA, Taipei, May 21, by reporter Su Su-yun) Facing rapidly evolving fraud techniques, the financial industry is continuously upgrading its technological anti-fraud capabilities. Cathay United Bank, in partnership with the Criminal Investigation Bureau (CIB), has introduced a behavioral analysis model for victim typologies, estimated to intercept up to NT$90 million in fraudulent funds annually. Fubon Insurance has also teamed up with Taiwan Mobile and Gogolook to launch a new digital anti-fraud picture book. Cathay United Bank announced today that it is deepening its cooperation with the CIB of the National Police Agency, Ministry of the Interior. This year, for the first time, the two parties have extended their anti-fraud mechanism to include behavioral analysis of 'victim typologies.' They have constructed an AI model training and validation mechanism that complies with regulations and protects personal data privacy, incorporating data and patterns from fraud cases investigated by the CIB to enhance the ability of front-line bank staff to identify abnormal cash flows and behaviors in real-time. Cathay United pointed out that a single financial institution relying solely on its internal data can hardly grasp the full behavioral characteristics of victims, leading to detection blind spots. To close this security gap, the two parties initiated data cooperation starting from 2025, combining fraud cases known to the CIB, including changes in account usage behavior and digital channel fraud patterns. This data is used for model validation, induction, and updates, significantly improving overall detection accuracy and timeliness. Cathay United Bank preliminarily estimates that it can intercept up to NT$90 million in fraudulent funds annually. Looking ahead, Cathay United will continue to deepen this joint defense mechanism and expand cross-domain cooperation in compliance with legal regulations and information security governance principles. The bank will also enhance its AI models to strengthen the identification of subtle and diverse victim behaviors. Fubon Insurance has also launched a new digital anti-fraud picture book, "Phew's Lab - Financial Anti-Fraud Classroom: The Anti-Fraud Helper Edition," in collaboration with Taiwan Mobile and Gogolook. The picture book presents professional anti-fraud knowledge and methods to strengthen the public's financial anti-fraud concepts and awareness. Fubon Insurance stated that with fraud methods constantly changing, there is a learning need for everyone, including the general public, children, and parents, regarding fraud patterns and risk identification. The newly launched anti-fraud picture book uses a story scenario of encountering fraud to guide people to recognize common fraudulent calls, text messages, and websites. Through character interaction and cases close to daily life, it aims to help them grasp key anti-fraud points, cultivate the ability to identify risks, and thereby reduce the probability of being scammed.
