TAIPEI (Taiwan News) — Taiwan Business Bank said Monday its AI-powered anti-scam model stopped approximately NT$150 million (US$4.8 million) in fraud so far this year, cutting newly flagged accounts by 35% year-on-year.

TBB said the system uses machine learning to track cash-flow patterns and behavioral anomalies, per CNA. Real-time alerts then allow staff to contact customers and prevent losses.

The bank said it expanded its anti-fraud budget this year to strengthen detection and upgrade its online warning system. It also integrated National Police Agency APIs and increased public outreach and staff training.

To speed up transfer blocking, the bank signed MOUs with the Taiwan High Prosecutors Office and the Criminal Investigation Bureau. Both agreements strengthen information-sharing and early prevention.

TBB said it also partnered with telecom operators to launch Taiwan’s first SIM-swap fraud defense mechanism. The system triggers multi-step verification during high-risk SIM actions to improve accuracy.

The bank said it will continue improving the model’s accuracy and responsiveness while expanding data-sharing with authorities.
