Researchers have developed a defense mechanism called Label Disguise Defense (LDD) to mitigate prompt injection attacks in Large Language Models (LLMs) used for sentiment classification. LDD works by substituting standard positive/negative labels with alternative pairs, such as "good/bad" or "cat/dog," and then mapping the model's predictions back to the original sentiment classes. While LDD showed improved performance over baseline labels in some configurations, consistent advantages were not observed across all tested models and label pairs. AI
IMPACT Introduces a novel defense strategy against prompt injection, potentially improving the robustness of LLMs in sensitive classification tasks.
