Polyguard: Anti-Deepfake Video Verification
Overview
Polyguard guarantees that who you see on your video call is who they really are. Our real-time, continuous verification system protects you from sophisticated impersonation attacks. Polyguard is currently available with Zoom, with support for Teams and Meet coming soon.
Problem: Next-Generation Impersonation Attacks
Threat Landscape: Attackers can generate deepfakes in real-time with ordinary computers, using personal data (photos, audio, etc.).
Targets: High and Ultra High Net Worth individuals, finance teams and professionals with authority over fund movements, advisors in real estate, institutional brokers, and wealth managers.
Non-Financial Impersonation Attacks include Kidnapping Scams targeting parents and grandparents, Romance Cons targeting lonely men through dating sites, Pig Butchering targeting cryptocurrency traders, and Political Attacks targeting military and diplomatic communications.
Problem: Pre-recorded Content
Risk: Attackers use pre-recorded deepfakes or clips for fraudulent purposes.
Solution: Polyguard warns you of pre-recorded content by popping out the sidebar and marking the user red.
Real-Time Deepfakes
Attackers can now generate deepfakes in real-time on ordinary computers, using personal data (photos, audio, etc.).
With Glass-to-Glass Verification, Polyguard makes it known if someone is perceptually modifying what their camera is capturing, causing the Polyguard App to pop open and highlighting that something isn't right.
Identity Proofing
How do you know WHO you're talking to?
Government ID proofing paired with cutting edge facial biometric detection, ensures that the name you see belongs to that person.
How It Works
With Polyguard, your video call streams are continuously signed, ensuring "WHO You See Is WHO You Get" verification. Polyguard requires:
- Polyguard Virtual Camera: Verifies the authenticity of the camera being used and digitally signs each frame.
- Polyguard App/Plugin: Compatible with Zoom (Teams and Meet coming soon) to integrate seamlessly into your conferencing environment.
- Polyguard Bot: When a meeting is started, and the Polyguard app/plugin is enabled on your Zoom account, a Polyguard Bot joins your meeting to complete the glass-to-glass verification, ensuring that the video in the call is perceptually the same as what the camera saw.
Participants can use any standard webcam. Within standard video conferencing apps like Zoom, Microsoft Teams or Google Meet, the Polyguard Bot verifies the signature for each participant. If there's any discrepancy between what was signed and what is displayed, you are immediately notified.
