Interview question · Software, Data & Model Supply Chain

How would you sign model artifacts and verify their provenance end to end?

A model is a directory, not a file. Sign the whole thing, tie the signature to the pipeline that produced it, and refuse to load anything that does not match.

What if · the follow-ups in this answer

The answer works through 6 follow-ups like an interviewer would

A team publishes model weights to an internal registry for other teams to use, and wants consumers to be able to trust what they load.

  1. What exactly should be signed?
  2. Who should sign?
  3. What provenance should accompany the signature?
  4. Where should verification happen?
  5. What does a valid signature not tell you?
  6. How would you implement model signing and verification?

Each rung has a nudge, a model answer, the principle that carries over and the weak answer to avoid. Sign in free to open it.
