Prove your photos are real without revealing who you are.
AI fakes are everywhere. C2PA proves photos are real but exposes the photographer. ProofFrame uses ZK proofs to verify authenticity and edits — crop, adjust, convert — while proving no pixels were tampered. All without revealing your identity.
ZKVM: RISC ZERO v1.0
Verified Edits
Crop, adjust brightness, convert to grayscale — and the ZK proof guarantees these are the only changes made. No deepfakes, no pixel manipulation. EXIF metadata (GPS, timestamps, device serials) is selectively disclosed or stripped entirely.
C2PA Standard
Built upon the Content Authenticity Initiative standards, optimized for zero-knowledge privacy.
No wallets, no accounts, no tracking.
Decentralized Trust
We don't verify your images—the math does. Our infrastructure uses RISC Zero's zkVM to execute verification logic off-chain and post the proof to Ethereum.
