PromptGraph enhances LLM privacy with graph-guided prompt sanitization

Researchers have introduced PromptGraph, a novel method for enhancing privacy in Large Language Model (LLM) inference. This approach models prompts as attributed graphs, where nodes represent individual spans with privacy scores and edges capture contextual dependencies crucial for maintaining utility. By optimizing for both privacy gain and the preservation of these contextual links, PromptGraph aims to strike a better balance between protecting sensitive information and ensuring the model's functional output compared to existing span-level sanitization techniques.

    PromptGraph: Graph-Guided Prompt Sanitization for Balancing Privacy and Utility in LLM Inference

    arXiv:2607.10709v1 Announce Type: cross Abstract: Large Language Model (LLM) services introduce a fundamental privacy challenge. Sensitive information may be inferred not only from explicit identifiers, such as names or phone numbers, but also from contextual associations among o…
