United We Defend: Collaborative Membership Inference Defenses in Federated Learning

Li Bai, Junxu Liu, Sen Zhang +3

Membership inference attacks (MIAs), which determine whether a specific data point was included in the training set of a target model, have posed severe threats in federated learni…

Toward Efficient Inference Attacks: Shadow Model Sharing via Mixture-of-Experts

Li Bai, Qingqing Ye, Xinwei Zhang +4

Machine learning models are often vulnerable to inference attacks that expose sensitive information from their training data. Shadow model technique is commonly employed in such at…

A Sample-Level Evaluation and Generative Framework for Model Inversion Attacks

Haoyang Li, Li Bai, Qingqing Ye +4

Model Inversion (MI) attacks, which reconstruct the training dataset of neural networks, pose significant privacy concerns in machine learning. Recent MI attacks have managed to re…

Membership Inference Attacks and Defenses in Federated Learning: A Survey

Li Bai, Haibo Hu, Qingqing Ye +3

Federated learning is a decentralized machine learning approach where clients train models locally and share model updates to develop a global model. This enables low-resource devi…
