+| API family name | Fraud Hotzone Report |
+| API family owner | Chunghwa Telecom |
+| API summary | This API analyzes recent SMS activity patterns for a suspected fraud victim's phone number. It detects anomalies based on adaptive AI models, taking into account fraud-prone countries or regions (fraud hotzones) specified by the user. The result helps determine whether the observed behavior indicates potential high-risk fraudulent targeting within the given lookback period. |
+| Technical viability | This API utilizes call and SMS activity data retrieved from mobile core network sources (e.g., IMS information) and applies our custom-designed adaptive AI algorithms, along with other detection methods, to identify abnormal communication behaviors associated with fraud hotspots and determine the dates on which such anomalies occurred.
+| Commercial viability | In current situation many scam organizations use phone call and SMS interactions to carry out fraudulent activities.
Challenges in Anti-Fraud Application Design:
•Accurately identifying whether a target number is high risk is difficult.
•Anti-fraud applications can only make educated guesses based on limited scenarios.
We propose the Communication Risk Check API, which provides anti-fraud indicators of target phone numbers. This enables anti-fraud applications to assess the risk from two perspectives: detecting potential scammers and protecting potential victims.|
