Overview

AdPriva makes web traffic verifiable, private and fraud-resistant while staying lightweight for real-world stacks.

It unifies local user control, publisher tagging, cryptographic proofs and blockchain anchoring into one coherent system.

Core Components

• AdPriva ID App (Users) → Secure vault for preferences and consent. All sensitive data stays encrypted on-device.
• AdPriva Tag / SDK (Publishers) → Lightweight, headless script/SDK that renders nothing, captures genuine engagement signals and emits cryptographic receipts (ViewProofs, ClickProofs).
• Proof Engine → Cryptographic core generating/validating Consent Receipts and Engagement Proofs.
• Verification Layer → Fast off-chain validation with batch on-chain anchoring for tamper-evidence and regulatory auditability.
• AdPriva Explorer → Public verification hub where publishers, users and auditors independently check proofs.

Modular by design: Each component (ID App, Tag/SDK, Proof Engine, Verification Layer, Explorer) can evolve independently and integrate with existing publisher tooling and analytics stacks.

High-Level Data Flow

1. User Preferences → Declared in the ID App and stored as encrypted Consent Receipts.
2. Page Load → Publisher page/app loads; the AdPriva Tag/SDK initializes.
3. Consent Check → The Tag validates consent before capturing any engagement signal.
4. Engagement → On view or click, the Tag/SDK generates a cryptographic receipt (proof).
5. Validation → Proof Engine checks integrity; Verification Layer validates at scale ( batch ZK + on-chain anchoring).
6. Explorer → Proof hashes/logs published to AdPriva Explorer for transparency, audits and compliance.

Architectural Guarantees

• Privacy-first → No personal data leaves the device; verification uses consent + cryptography, not tracking.
• Verifiable → Every engagement is tied to a cryptographic proof/receipt.
• Scalable → Off-chain validation for speed; batch anchoring/ZK for tamper-evidence at scale.
• Interoperable → Works alongside existing publisher tooling and analytics stacks.
• Transparent & Compliant → Proofs are auditable in Explorer; designed for GDPR/ePrivacy/CCPA.
