Differential privacy fails to protect vulnerable subgroups in synthetic text releases

By PulseAugur Editorial · [1 sources] ·

A new audit of differentially private synthetic text releases reveals that while differential privacy (DP) is effective at reducing average membership inference leakage, it disproportionately protects some records over others. The research defines a subgroup-targeted membership inference game to quantify this risk, showing that synthetic releases can still leak subgroup membership. The study also highlights that the specific records leaking information depend on the release mechanism used, not solely on the record itself. AI

IMPACT Highlights potential privacy risks in synthetic data generation, urging caution in deploying models trained on such data.

    Subgroup Membership Inference Audits of Differentially Private Synthetic Text

    arXiv:2609.09848v1 Announce Type: cross Abstract: Synthetic data releases are increasingly proposed in the literature as a means of sharing realistic data replicas in lieu of sensitive private datasets. Even when the worst-case privacy leakage of such releases is bounded by means…
