Reported viewing metrics are useful. Verification makes them stronger.
Existing media systems can report delivery, playback, and completion. ProofView adds a complementary verification layer for defined human presence and attention conditions during the session.
Proof infrastructure for defined viewing conditions.
Local processing, privacy-preserving proof generation, and independent verification work together without making the underlying biometric measurements part of the server payload.
From local measurement to verifiable receipt.
Viewing and attention signals are processed locally during media playback. Defined verification conditions are converted into a Groth16 zero-knowledge proof. The proof and associated session integrity are independently verified, and a cryptographic receipt records the verified outcome.
ProofView, explained clearly.
What is ProofView?
ProofView is a privacy-preserving verification layer for digital media and advertising. It is designed to cryptographically verify defined human viewing and attention conditions during media playback without transmitting the underlying biometric measurements.
How does ProofView protect user privacy during ad verification?
ProofView processes viewing and attention signals locally in the browser and uses zero-knowledge proof technology to verify defined conditions without transmitting the underlying biometric measurements to the verification server.
