Verifiable AI and the EU AI Act: proving what your AI decided
EU AI Act Article 12 requires decision logs for high-risk AI. Your own logs are editable. Here is how to make AI decisions tamper-evident and quantum-safe.
AI is moving into decisions that move money: credit approvals, insurance underwriting, eligibility, automated trading. The EU AI Act (Article 12, applying from August 2026) requires high-risk AI systems to keep automatic logs over their lifetime for traceability.
The honest problem: your own logs are editable by you. "Trust me, the model said so" is not auditable, and a log you can rewrite is not evidence after an incident. Regulators, auditors and insurers want non-repudiable records — ones the operator could not have altered.
The fix is to sign each decision and anchor it. ProofMind signs an AI decision record — (input hash, output hash, model id, timestamp) — with a post-quantum signature (Dilithium-2, NIST FIPS 204) and verifies it before anchoring. Tamper one byte and verification fails. A black-box variant keeps an append-only, chained log of an agent's entire conduct, so a gap or edit is detectable.
What this proves and does NOT: it proves authenticity, integrity, ordering and quantum-resistance of the decision — not that the model's reasoning was correct (that is an open research problem). Saying so openly is the point: regulators respect a precise claim, not "verifiably honest AI". Try it live and verify it yourself.
