Family Safe Word

Scripts and rules that stop panic and force identity verification in calls and texts.

Explanations beat “yes/no”

People spot scams better when they see the reasoning. Shield Check is built around that insight.

1. PAUSE → 2. VERIFY → 3. CALL-BACK

📞 The “Bank” Call

Voice cloning is real. Shield gives you a short script that breaks urgency and forces verification.

📱 The FaceTime Deepfake

Looped video and impersonation tactics work because people react fast. Your protocol makes the scam fail.

The goal isn’t “trust AI.” The goal is “slow down, verify, and make the scam prove itself.”
