ProofView — Privacy-Preserving Ad Verification
Explore how defined viewing and attention conditions can be converted into independently verifiable cryptographic evidence while keeping the underlying biometric measurements private.

Initiate Verification Session
ProofView evaluates presence and attention client-side during playback. At completion, a Groth16 zero-knowledge proof is generated from the whole-session evaluation without transmitting the underlying biometric measurements to the verification server.

Privacy by design
Session measurements remain private while the verification outcome can be independently checked.
