ARCHANGEL
The Evidence Layer for AI Consent Governance
Cryptographic receipts that prove what actually happened. Not what someone claims happened.
The Problem
Audit logs are alterable. They prove what you say happened. They can be edited, deleted, or fabricated. When a regulator or court asks for proof of consent, logs are claims — not evidence.
Policy-based consent — TOS checkboxes, opt-out letters, database flags — is a promise. It can be overridden, ignored, or lost. It does not enforce anything at runtime.
The enforcement gap is not a compliance checkbox problem. It is an infrastructure problem.
The Solution
ARCHANGEL is a cryptographic evidence layer. Every AI action passes through a consent gate. The gate evaluates a consent token against the current policy state. If the token is valid, the action executes and a signed receipt is issued. If the token is invalid or absent, the action is denied. Fail-closed. No exceptions.
Every decision — ALLOW or DENY — produces a cryptographic receipt. Dual-signed with classical and post-quantum cryptography. Chain-linked. Tamper-evident. Verifiable offline by any third party.
Key Properties
Fail-Closed Enforcement
No valid receipt = no execution. If the gate cannot verify consent, it denies. The default state is denial, not permission.
Instant Revocation
Consent tokens invalidated in a single operation across all enforcement points. No propagation delay.
Audit-Grade Evidence
Receipts prove who authorized, what happened, which policy governed, and when. Signed, timestamped, tamper-evident. Not database records — math.
Offline Verification
Export a receipt bundle with public keys. Any auditor or regulator can verify independently. No platform access needed.
Post-Quantum Ready
Quantum-resistant signatures from day one. Resistant to harvest-now-decrypt-later attacks.
Sub-8ms Verification
Real-time enforcement. Benchmarked and verified. All SLAs met.
The Enforcement Stack
Consent Gate
Patent PendingCryptographic consent verification. The foundation. Every action must present a valid consent token or it doesn't execute.
Receipt Rail
Patent PendingTamper-evident, chain-linked receipt system. Every decision generates a signed receipt. Third-party verifiable offline.
Likeness Enforcement
Patent PendingNo consent token = no voice clone, no face synthesis. Cryptographic permission before any synthesis.
GPU Gate
Patent PendingHardware-level enforcement. No governance receipt = no compute allocation = no inference.
