MEraser: An Effective Fingerprint Erasure Approach for Large Language Models

Jingxuan Zhang and Zhenhua Xu (co-first authors), Rui Hu, Wenpeng Xing, Xuhong Zhang, Meng Han Code

LLMs are widely used, raising concerns about model ownership. MEraser is a method to remove backdoor-based fingerprints from LLMs while preserving performance. It uses a two-phase fine-tuning strategy with mismatched and clean datasets, achieving fingerprint removal with minimal data. The method is transferable across models without repeated training, highlighting vulnerabilities in current techniques and setting benchmarks for better model protection.
