Telecom Fraud Prevention

Overview

As telecommunication fraud tactics continue to evolve, scam syndicates exploit multiple channels—such as international calls, hidden caller IDs, spoofed numbers, fake roaming numbers, malicious text messages, and phishing links—to conduct fraudulent activities, posing a serious threat to public communications security. In response, our company has established a comprehensive protection framework encompassing voice scam prevention, text message scam prevention, and GSMA Open Gateway APIs, delivering a multi-layered anti-fraud defense across the network layer, application layer, and through industry-wide collaboration.

In voice scam prevention, multiple call-filtering mechanisms are employed, including detection of spoofed international calls, calls with hidden caller IDs, blacklisted numbers, and illegal roaming activities. In addition, real-time voice alert services are provided for international calls and calls with hidden caller IDs, and call content scam detection technologies are being explored to further reduce the likelihood of fraud.

In text message scam prevention, in response to the severe global challenge of SMS fraud, our company leverages large language models for semantic scam detection, combined with machine learning–based malicious URL detection, scam keyword filtering, and fraudulent LINE ID identification technologies. Together, these capabilities form a comprehensive risk analysis mechanism for SMS content and embedded links, establishing a real-time, high-accuracy anti-fraud defense.

In industry-wide collaboration, our company has joined the GSMA Open Gateway initiative to actively promote the exposure of 5G network capabilities. Through a globally standardized API framework, we monitor high-risk behaviors such as abnormal SIM card replacement and issue risk alerts accordingly, strengthening upstream risk control and transforming core telecommunications capabilities into cross-industry, consumable security services.

Application Status

Voice Scam Prevention Technology:Our company took the lead domestically in developing and launching a fixed-line international call alert service, providing real-time voice warnings in both Mandarin and Taiwanese for international incoming calls in 2023. In 2026, we further pioneered the introduction of a mobile network hidden caller ID alert service, enhancing users’ ability to identify risks at the earliest stage. For specific high-risk sources and suspicious traffic from Type II telecommunications operators, we have developed abnormal call filtering systems applicable to both fixed and mobile networks in 2023, enabling caller number identification, blocking, and alerting to effectively reduce scam call exposure to users. In addition, we are advancing call content scam detection technologies, making voice scam prevention more intelligent.
SMS Scam Prevention Technology:The AI-powered SMS scam prevention technology developed by our company has been successfully deployed on commercial SMS platforms, analyzing tens of millions of messages daily. By leveraging large language models for semantic analysis in combination with machine learning–based malicious URL detection, the system enables real-time detecting of high-risk scam content. These achievements have significantly reduced the circulation risk of fraudulent SMS messages and have received strong recognition from the industry. In 2024, the solution was awarded the Digital Transformation Dingge Award – Smart Management Transformation Award (Model Award, Large Enterprise Category), followed by the Silver Medal at the 2025 Taiwan Innotech Expo, demonstrating both technological innovation and successful real-world deployment.
GSMA Open Gateway API Technology:Our company has developed a Network Capability Platform based on GSMA/CAMARA standard APIs, enabling banks, financial institutions, and government agencies to securely query telecommunication data to enhance identity verification and risk management capabilities. The platform fully adopts the OAuth 2.0 third-party authorization mechanism to ensure data privacy and secure access throughout the API integration process. By capturing and analyzing signaling and traffic data from the 5G core network, telecommunications network capabilities are transformed into standardized, reusable services. The related outcomes have been publicly presented at Taipei FinTech Forum in 2025.
