New audit reveals EEG foundation models leak spectral attributes

Researchers have developed a new auditing framework for EEG foundation models, revealing that existing single-endpoint audits are insufficient to detect attribute leakage. Their method, which involves a cross-encoder transfer audit, demonstrated that spectral attributes can still be transferred even when models are frozen and appear secure. Standard defenses like noise-aware attackers and DP-SGD were found to be ineffective against this new auditing technique. AI

IMPACT Introduces a more robust auditing method for foundation models, potentially impacting privacy and security practices in AI development.

    Pretrained, Frozen, Still Leaking: Auditing Cross-Encoder Attribute Transfer in EEG Foundation Models

    arXiv:2606.09189v1 Announce Type: cross Abstract: EEG foundation-model releases are usually audited one endpoint at a time: raw-reconstruction, membership inference, identity linkage, or DP-SGD on the downstream head. We audit the same released embeddings under all four endpoints…
