Polyguard is a real-time identity verification platform designed to secure video calls, remote interviews, and high-stakes virtual meetings against deepfakes and impersonation. The system utilizes a mobile application to capture biometric data and government-issued identification, validating participant identities before they join meetings on platforms like Zoom and Microsoft Teams. It employs hardware-backed local credential storage, 3D depth sensing, and device tamper-proofing to ensure secure, privacy-compliant identity proofing without centrally aggregating sensitive data.
