- ✅ Zero-knowledge proof for consent verification
- ✅ Consent expiry checking
- ✅ Purpose hash verification
- ✅ Privacy-preserving consent management
- ✅ GDPR/CCPA compliant
- ✅ Patent-protected implementation (Claim 9)
- ✅ Stateless verification
- GDPR Compliance: Verify user consent without exposing consent data
- CCPA Compliance: Privacy-preserving consent verification
- Healthcare: HIPAA-compliant consent management
- Marketing: Privacy-preserving consent for data processing
- Enterprise: Consent verification in access control systems
- FinTech: Regulatory consent verification
The circuit verifies:
- Consent hash exists and is valid
- Consent is active (not expired)
- Purpose hash matches intended use case
All verification happens without exposing the actual consent data.
