CriNet transforms scam detection from reactive to real-time. Instead of filing a complaint after losing money, victims get warned during the call itself. The system can be deployed as a background service on any Android phone, acting as an always-on scam shield for vulnerable users — elderly parents, children, anyone who might not recognize a scam in progress.
Demo Flow
1. Open the CriNet dashboard on a phone browser (/app)
2. Trigger an outbound call via API: POST /call/start with scammer and victim numbers
3. Scammer answers → victim's phone rings → call is bridged
4. Scammer reads a script: "Sir, I need your OTP to verify your account..."
5. Gemini detects the OTP request pattern → fires flag_scam_alert
6. Phone screen flashes red, vibrates, shows: OTP REQUEST — 97% confidence — "Caller requested OTP for account verification"
