Privacy Leakage on DNNs: A Survey of Model Inversion Attacks and Defenses
Model Inversion (MI) attacks aim to disclose private information about the training data by abusing access to the pre-trained models. These attacks enable adversaries to reconstruct high-fidelity data that closely aligns with the private training data, which has raised significant privacy concerns. Despite the rapid advances in the field, we lack a comprehensive overview of existing MI attacks and defenses. To fill this gap, this paper thoroughly investigates this field and presents a holistic survey. Firstly, our work briefly reviews the traditional MI on machine learning scenarios. We then elaborately analyze and compare numerous recent attacks and defenses on \textbf{D}eep \textbf{N}eural \textbf{N}etworks (DNNs) across multiple modalities and learning tasks.
