- ✅ Zero-knowledge proof generation for audit logs
- ✅ Privacy-preserving data verification
- ✅ Cryptographic integrity verification
- ✅ GDPR/CCPA compliant audit trails
- ✅ Patent-protected implementation (Claims 6, 9)
- ✅ Stateless verification
- Financial Compliance: Audit trails for transactions without exposing customer data
- Healthcare: HIPAA-compliant audit logs for patient data access
- Enterprise: Privacy-preserving audit logs for access control systems
- Blockchain: On-chain audit verification without data exposure
- RegTech: Compliance reporting with privacy guarantees
The circuit generates an audit proof hash from:
- Decision value
- Timestamp
- Pseudonymised user ID
- Rules hash
All inputs remain private while allowing verification of audit log integrity.
