arXiv:2409.01062v4 Announce Type: replace Abstract: Model Inversion (MI) attacks pose a significant privacy threat by reconstructing private training data from machine learning models. While existing defenses primarily concentrate on model-centric approaches, the impact of data on MI robustness remains largely unexplored. In this work, we explore Random Erasing (RE), a technique traditionally used for improving model generalization under occlusion, and uncover its surprising effectiveness as a defense against MI attacks. Specifically, our novel feature space analysis shows that models trained
The proliferation of machine learning models in sensitive applications is driving an urgent need for robust privacy defenses, making research into practical and effective solutions like Random Erasing highly relevant.
This research provides a new, potentially effective, and data-centric approach to defend against Model Inversion attacks, addressing a critical privacy vulnerability in AI systems.
The focus of model privacy defense may broaden to include data preprocessing techniques, rather than solely relying on model architecture or post-processing methods.
