New attack infers temporal data membership in continually updated AI models

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced TMIA, a novel black-box attack designed to infer temporal membership in continually updated deep learning models. This attack aims to determine if and when specific data samples were used during model training, operating at both timestamp and interval levels. TMIA utilizes bidirectional LSTMs to analyze model outputs across successive updates, demonstrating significant effectiveness over existing methods in experiments with language and image classification models. The study also explores potential defenses, highlighting the inherent trade-off between privacy and model utility. AI

IMPACT This research highlights a new privacy risk in continually updated AI models, potentially influencing future development and defense strategies.

    Timing is Everything: Inferring Temporal Membership in Continually Updated Models

    arXiv:2611.05781v1 Announce Type: cross Abstract: Continual model updating has become a common practice in the deployment of machine learning systems. However, the dynamic training behaviors give rise to new risks not sufficiently addressed by existing studies. In this paper, we …
