Proof Systems & Verification

Every engagement becomes cryptographic evidence private, verifiable and fraud-proof.

AdPriva replaces cookies, pixels and heuristic filters with proof-backed traffic validation that ensures:

  • Publishers → Prove their traffic is genuine and build verifiable trust.
  • Users → Stay private and stay in control of their consent.
  • Auditors → Independently verify traffic quality with cryptographic evidence.

Proof Types in AdPriva

  • Consent Receipts → Verifies that a user explicitly set their consent preferences. Generated whenever preferences are updated in the AdPriva ID App.
  • Bounded-Use Proofs → Proves engagement was only recorded within user-approved consent bounds, ensuring strict compliance.

Engagement Proofs

  • ViewProofs → Confirms a page view was genuine (viewport, focus, dwell time, consent).

    → Use case: Verified human views.

  • ClickProofs → Proves a click was human, unique and valid (entropy checks, velocity patterns, cryptographic signing).

    → Use case: Verified human clicks.

Meta Proofs

  • Tamper-Evident Snapshots → Immutable logs that seal proof history.

Verification Workflow

  1. Trigger → An engagement event occurs (view or click).
  2. Proof Generation → Tag/SDK issues a cryptographic proof, bound to consent + context.
  3. Validation Layer → Proofs validated in real time off-chain; cohorts batch-verified with ZKPs and anchored on-chain.
  4. Explorer Logging → Proofs published in the AdPriva Explorer for transparency and audits.
  5. Certification → Validated, anchored proofs form a tamper-evident record publishers and auditors can independently verify.

Fraud Prevention via Proofs

  • Replay protection → Nonces + expiry stop reuse.
  • Bot resistance → Proofs require live human signals (scroll, focus, dwell).
  • Consent enforcement → Engagement is never recorded outside user-approved consent.
  • ZK validation → Batch-verified proofs at scale without exposing data.
  • Tamper-evidence → Immutable Merkle-root snapshots prevent manipulation.

With AdPriva’s proof system, web traffic evolves from black-box guesswork to proof-backed, fraud-resistant, auditable truth at scale.
