New audit method quantifies privacy leakage in federated data generation

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method to audit user-level privacy in federated settings, specifically for Private Evolution (PE) systems. This empirical audit protocol involves the server committing to a candidate bank and then replacing a small percentage of entries with specially crafted "canary" probes. Experiments on datasets from Yelp and Sentiment140 demonstrated that while natural-text attacks showed minimal privacy leakage, nonce-based attacks came closer to the theoretical differential privacy bound, quantifying the gap between formal privacy guarantees and practical leakage. AI

IMPACT This research provides a method to better understand and quantify privacy risks in federated learning systems, potentially influencing the design of more secure AI models.

    Canaries in the Bank: Auditing User-Level Privacy in Private Evolution

    arXiv:2609.13499v1 Announce Type: cross Abstract: Private Evolution (PE) generates high-fidelity synthetic data in federated settings without exposing users' raw data. It aggregates clipped user votes over a shared candidate bank into a differentially private histogram, with nois…
