About Circadify's Mission
Making deepfakes irrelevant by anchoring identity verification to the one signal that cannot be synthesized — real blood flow
Why We Built Physiological Liveness Detection
The identity verification industry faces an arms race it is losing. Every improvement in facial recognition is matched by improvements in synthetic media generation. Deepfakes that were obvious two years ago are now indistinguishable from real footage. Traditional anti-spoofing — challenge-response prompts, texture analysis, artifact detection — is pattern matching against an ever-expanding attack surface.
We asked a different question: instead of trying to detect what a deepfake looks like, what if we detect what it fundamentally lacks? The answer is blood flow. Remote photoplethysmography proves that a camera can read the hemodynamic signals pulsing beneath human skin. No generative AI model produces these signals because they arise from actual cardiovascular biology, not from pixels.
Circadify applies rPPG as a liveness layer for identity verification, banking authentication, and KYC workflows. Rather than racing to identify new deepfake artifacts, we verify the presence of an unforgeable biological signal. This is not pattern matching — it is proof of life. We built TryFaceScan to show fraud teams, identity vendors, and security leaders what physiological liveness detection makes possible.
Our Mission
To make deepfake fraud structurally impossible by shifting identity verification from visual appearance to physiological reality — proving that the person on camera has real blood flowing through real veins, a signal no synthetic media can replicate.
The Principles Behind Our Detection Technology
Biology Over Pixels
We do not analyze how a face looks. We analyze whether it is alive. This distinction makes our detection approach fundamentally resistant to advances in generative AI — because the attack surface is biology, not visual fidelity.
Privacy Through Architecture
Facial video is sensitive biometric data. Rather than promising to protect it after collection, we architected Circadify so video never leaves the capture device. You cannot breach data you never transmit.
Zero Friction for Real Users
Security measures that degrade user experience get disabled. Circadify runs passively — no blinking challenges, no head turns, no additional steps. Legitimate users pass without noticing. Only synthetic identities fail.
Deploy on Existing Infrastructure
Requiring specialized cameras or dedicated hardware limits adoption. Circadify works with the standard RGB cameras already in the devices your customers use, making enterprise-grade liveness detection accessible without hardware investment.
