Researchers build Real-time romance scam chatbot using Line API
A team of researchers has developed a chatbot that detects romance scams in real time via the Line Messaging API. The system uses a large language model to analyze conversations against seven established stages of social engineering in romance scams. When a potential scam is flagged, the chatbot explains the detected stage and offers prevention advice, all generated by the model.
Key points
- Chatbot uses Line Messaging API to monitor conversations for romance scam red flags in real time
- Detects scams by matching conversations to seven social science-defined stages of manipulation
- Provides explanations of detected stages and prevention advice via the same large language model
The work, posted on arXiv, is framed as a practical application to reduce risks in real-world scenarios. The chatbot’s design leverages existing social science theories to classify suspicious behavior dynamically. No deployment details or user testing are mentioned in the abstract.
