Researchers have developed PromptPET, a novel system designed to enhance user privacy when interacting with AI chatbots. PromptPET employs an LLM-based agent that optimizes prompt obfuscation by selecting from four actions: redaction, abstraction, replacement, and a new noising/denoising scheme. This approach aims to strike a balance between protecting sensitive user information and maintaining the utility of chatbot responses, outperforming existing methods on real-world chat datasets. AI
IMPACT Enhances user privacy in AI chatbots by obfuscating sensitive information while preserving response utility.
