LLMs and Contextual Integrity

Schneier on Security

Recent research has raised concerns about the privacy risks associated with Large Language Models (LLMs) that utilize persistent memory from past interactions. A benchmark called CIMemories was introduced to evaluate how these models manage sensitive information based on context. The study revealed that leading models, like GPT-5, can leak personal attributes in inappropriate contexts, with violation rates increasing significantly as usage grows. For example, violations jumped from 0.1% to 25.1% when the same prompt was repeated multiple times. These findings indicate that current models struggle with making nuanced decisions about information sharing, suggesting a need for improved context-aware reasoning capabilities.
