AI accountability

How do I prove an AI decision occurred?

The short answer

To prove an AI decision occurred, generate a signed proof artifact at the moment of the decision that commits to the model identity and version, the decision output, the governing policy, the oversight context, and a timestamp. Any party can then independently verify the proof without trusting the system that produced it — and without exposing the sensitive inputs.

Explanation

An AI decision is only defensible if you can demonstrate, after the fact, exactly what the system did. Internal logs and dashboards are insufficient because they must be trusted and can be altered. Proof infrastructure solves this by emitting a proof artifact for each significant AI action, turning an opaque model output into independently verifiable evidence.

The proof does not attempt to establish that the decision was "correct" — that is a matter of model validation and policy. It proves the facts: which model version decided what, when, under which policy, and with what human oversight. This is the foundation of AI accountability and verifiable AI.

How to do it

  1. 1Capture the decision context: model identity, version, governing policy, and oversight state.
  2. 2Commit to sensitive inputs and the output with cryptographic hashes (never store the raw data in the proof).
  3. 3Generate a signed proof artifact binding the commitment, issuer authority, and timestamp.
  4. 4Store or transmit the artifact alongside the decision record.
  5. 5Allow any party to verify the artifact independently — integrity, signature, authority, and timing.

Examples

Automated loan denial

A credit model declines an application. A proof artifact records model v4.2, the decision, the policy, and the reviewer oversight — verifiable by a regulator without exposing the applicant’s data.

Autonomous agent action

An AI agent executes a transaction. The proof attributes the action to a specific agent identity and authority, so responsibility is provable.
