Cryptographic Vault & Legal Proof Export

The Compliance Vault records an immutable, tamper-proof cryptographic ledger of every consent transaction, providing court-admissible evidence against statutory wiretap claims.

The SHA-256 Audit Proof Structure​

Whenever a visitor grants or revokes consent, Consent Shield creates a signed JSON payload containing:

{
  "proof_id": "cs-proof-9842a8f-20260820-utc",
  "site_id": "CS-LIVE-PROD",
  "visitor_hash": "e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855",
  "timestamp_utc": "2026-08-20T21:40:00Z",
  "jurisdiction": "US-CA",
  "applicable_law": "CCPA_CIPA",
  "consent_state": {
    "necessary": true,
    "analytics": false,
    "marketing": false
  },
  "gpc_signal_received": true,
  "sha256_signature": "8f3a9e2d1c0b7a4e6f8d2c1b9a8e7f6d5c4b3a2e1d0c9b8a7f6e5d4c3b2a1e0f"
}
