New method audits LLM privacy risks with synthetic canary examples

Researchers have developed a new method for empirically auditing the privacy risks associated with fine-tuning large language models. The technique involves generating synthetic "canary" examples using high-temperature sampling from LLMs, which are then mixed with sensitive training data to identify potential data leakage. This approach also allows for auditing the privacy implications of generating synthetic data from fine-tuned models. AI

    Advancing the State-of-the-Art in Empirical Privacy Auditing

    Parameter-efficient fine-tuning of large language models (LLMs) can exhibit problematic memorization of individual training examples. Empirical privacy auditing (EPA) quantifies this risk by measuring realistic data leakage on membership inference (MI) or reconstruction attacks. …
