Pre-trained Encoders in Self-Supervised Learning Improve Secure and Privacy-preserving Supervised Learning

Hongbin Liu, Wenjie Qu, Jinyuan Jia +1

Classifiers in supervised learning have various security and privacy issues, e.g., 1) data poisoning attacks, backdoor attacks, and adversarial examples on the security side as wel…

FedRecover: Recovering from Poisoning Attacks in Federated Learning using Historical Information

Xiaoyu Cao, Jinyuan Jia, Zaixi Zhang +1

Federated learning is vulnerable to poisoning attacks in which malicious clients poison the global model via sending malicious model updates to the server. Existing defenses focus…

MultiGuard: Provably Robust Multi-label Classification against Adversarial Examples

Jinyuan Jia, Wenjie Qu, Neil Zhenqiang Gong

Multi-label classification, which predicts a set of labels for an input, has many applications. However, multiple recent studies showed that multi-label classification is vulnerabl…

EncoderMI: Membership Inference against Pre-trained Encoders in Contrastive Learning

Hongbin Liu, Jinyuan Jia, Wenjie Qu +1

Given a set of unlabeled images or (image, text) pairs, contrastive learning aims to pre-train an image encoder that can be used as a feature extractor for many downstream tasks. I…

BadEncoder: Backdoor Attacks to Pre-trained Encoders in Self-Supervised Learning

Jinyuan Jia, Yupei Liu, Neil Zhenqiang Gong

Self-supervised learning in computer vision aims to pre-train an image encoder using a large amount of unlabeled images or (image, text) pairs. The pre-trained image encoder can th…
