VérifVoix — Anti deepfake

A voice can be cloned by AI in seconds. So can a face. But not a private key. Deepfake scams are exploding: an "urgent" call with the exact voice of your child, a parent, or your boss—or even a video call with their face, faked live—asking for money. VoiceVerification lets you verify in seconds that the person on the other end is who they claim to be, regardless of the channel: phone, WhatsApp, FaceTime, Teams, Zoom, video call…

HOW DOES IT WORK?

1. 🔑 Upon installation, your phone generates a pair of cryptographic keys. The private key never leaves the device.

2. 🤝 You pair with your loved ones in person, just once, by scanning each other's QR codes.

3. ✅ During a suspicious call, open the app: both your phones will display the same 6-digit code, which changes every 30 seconds. Ask the caller to read it aloud. Identical code = it's really them. Different code or hesitation = hang up.

An imposter, even with a perfectly cloned voice—or a face manipulated live in a video call—cannot know this code: they don't have your loved one's phone. This is what makes VoiceVerification effective where "recognizing the voice" or "seeing the face" proves nothing.

100% PRIVATE, 100% OFFLINE

• No account, no server, no data collected

• Encrypted keys stored only on your device
• Free for up to 4 paired contacts

PRO MODE (ONE-TIME PURCHASE) — FOR BUSINESSES

The deepfake version of "CEO fraud" targets businesses: a call with the CEO's voice orders an urgent wire transfer. Pro Mode addresses this:

• 👥 Unlimited contacts (the free version is limited to 4)
• ✍️ Signed orders: every sensitive order (wire transfer, transaction, etc.) is cryptographically signed by the ordering party's phone and verified by the recipient. Without the private key, no valid order can be created—even with a perfect voice.

• 🏢 Labels by agency or department
• 🔒 Biometric unlocking before sensitive operations
• 📋 Time-stamped log of verifications, exportable as a CSV file
• ⚠️ One-click alert notification to your email

Implement the rule: "No phone order executed without a VerifVoix signature."

Security through cryptography, not voice recognition. Voices can be cloned. Keys cannot.
