In-Context Probing for Membership Inference in Fine-Tuned Language Models

arXiv — cs.LGTuesday, December 23, 2025 at 5:00:00 AM
  • A novel framework named In-Context Probing for Membership Inference Attacks (ICP-MIA) has been proposed to address privacy concerns in fine-tuned large language models (LLMs). This framework leverages the concept of the Optimization Gap, which indicates the potential for further optimization in model training, distinguishing between member and non-member samples.
  • The introduction of ICP-MIA is significant as it aims to enhance the security of LLMs against membership inference attacks, which can expose sensitive data used during model training. By focusing on training dynamics, this approach seeks to improve the robustness of LLMs in domain-specific applications.
  • This development highlights ongoing challenges in AI regarding privacy and security, particularly as LLMs become increasingly integrated into sensitive applications. The exploration of membership inference and related privacy vulnerabilities reflects a broader trend in AI research, emphasizing the need for effective mechanisms to safeguard user data while maintaining model performance.
