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.| +| YAML code available? | NO. | +| Validated in lab/productive environments? | NO. | +| Validated with real customers? | NO. | +| Validated with operators? | NO. | +| Supporters in API Backlog Working Group | Chunghwa Telecom | diff --git a/documentation/SupportingDocuments/Fraud Hotzone Report.pptx b/documentation/SupportingDocuments/Fraud Hotzone Report.pptx new file mode 100644 index 0000000..a3bfce0 Binary files /dev/null and b/documentation/SupportingDocuments/Fraud Hotzone Report.pptx differ
