arXiv:2509.03122v4 Announce Type: replace Abstract: Reliable model fingerprints are essential for protecting large language models (LLMs) against unauthorized redistribution and commercial misuse. In black-box deployment, verification is hindered by defensive filtering of suspected fingerprint queries, as well as by downstream model modifications that may weaken embedded ownership evidence. These risks require fingerprints to be robust in both construction and injection. For construction, prior paradigms face an imperceptibility trade-off: natural-language fingerprints may be accidentally acti
The proliferation of advanced LLMs and their increasing commercial value has made ownership verification and protection a critical and immediate concern.
This development addresses the core challenge of intellectual property rights for AI models, which is crucial for fostering innovation and preventing unauthorized use in a rapidly evolving market.
New methods for robustly embedding and verifying ownership in LLMs will make it harder to illegally redistribute or modify proprietary models without detection.
