Re-Key-Free, Risky-Free: Adaptable Model Usage Control

ArXi:2511.18772v2 Announce Type: replace-cross Deep neural networks (DNNs) have become valuable intellectual property of model owners, due to the substantial resources required for their development. To protect these assets in the deployed environment, recent research has proposed model usage control mechanisms to ensure models cannot be used without proper authorization. These methods typically lock the utility of the model by embedding an access key into its parameters.
