Glossary
Updated
A storage mechanism (e.g., specialized object-storage tiers, append-only ledgers) where once data is written it becomes unchangeable. AI governance uses WORM to retain provenance records, compliance logs, and certified model versions, guaranteeing that historical artifacts remain tamper-proof. Policies specify retention periods, access controls, and verification routines to confirm immutability.
Example
A bank’s ML platform writes all model audit logs and dataset snapshots to a WORM bucket in its cloud provider. Regulators periodically verify the bucket’s immutability settings, ensuring no retrospective alterations have occurred and maintaining trust in audit records.
