From Construction to Injection: Edit-Based Fingerprints for Large Language Models

Researchers propose a novel fingerprinting framework for large language models that combines Code-mixing Fingerprints (CF) and Multi-Candidate Editing (MCEdit) to protect against unauthorized redistribution and commercial misuse. The approach addresses key vulnerabilities in existing fingerprinting methods by balancing imperceptibility with robustness against defensive filtering and downstream model modifications.

FIT-Print: Towards False-claim-resistant Model Ownership Verification via Targeted Fingerprint

Researchers introduce FIT-Print, a new model fingerprinting technique that defends against false ownership claims on AI models by using targeted signatures rather than arbitrary outputs. The method achieves 100% success in preventing fraudulent ownership assertions while maintaining perfect legitimate verification rates, addressing a critical vulnerability in existing intellectual property protection mechanisms for machine learning models.

LLM Self-Recognition: Steering and Retrieving Activation Signatures

Researchers demonstrate that large language models can reliably self-recognize their own outputs through implicit signals encoded in generated text, and this capability can be amplified through targeted steering of internal activation patterns. By injecting sparse random vectors into a model's residual stream during generation, they create detectable fingerprints enabling attribution to specific LLMs with over 98% accuracy while maintaining text quality. This approach offers a practical alternative to traditional AI-generated content detection by leveraging models' natural representation structures.
