Taiwan Telecom Association and High Prosecutors Office Sign LOI: AI Big Data to Enable Preemptive Fraud Warning

On October 19, 2026, the Taiwan Telecommunications Industry Development Association and the Taiwan High Prosecutors Office signed a Letter of Intent (LOI) for a 'Telecom Anti-Fraud Collaboration Mechanism.' The initiative involves the three major carriers: Chunghwa Telecom, Taiwan Mobile, and Far EasTone Telecommunications. This move signals an attempt by Taiwan's public and private sectors to shift anti-fraud strategies from reactive interception to proactive warning based on data analysis.

According to reports, the mechanism plans to utilize Artificial Intelligence (AI) and big data analytics to identify abnormal communication behaviors in real-time. Tsai Ming-chung, Chairman of the Association, noted that as fraud schemes increasingly combine AI-generated imagery, voice cloning, and cross-border crimes, reliance on government or individual companies alone is insufficient. The collaboration aims to integrate accumulated anti-fraud experience from telecom operators to establish a more immediate inter-agency defense network.

It is important to note that this is currently only a Letter of Intent, not an enacted law or a fully deployed technical system. Details regarding how the AI models will balance privacy protection with risk identification, and the legal boundaries for prosecutorial access to data, remain to be published. Previously, Taiwan's telecom operators had cumulatively blocked over 120 million fraudulent SMS messages and 35 million overseas scam calls; the new mechanism seeks to further reduce the incidence of such events.
