Defense without Forgetting: Continual Adversarial Defense with Anisotropic & Isotropic Pseudo Replay
Yuhang Zhou, Zhongyun Hua
Deep neural networks have demonstrated susceptibility to adversarial attacks. Adversarial defense techniques often focus on one-shot setting to maintain robustness against attack.…
Seeing is not Believing: An Identity Hider for Human Vision Privacy Protection
Tao Wang, Yushu Zhang, Zixuan Yang +3
Massive captured face images are stored in the database for the identification of individuals. However, these images can be observed unintentionally by data managers, which is not…
Privet: A Privacy-Preserving Vertical Federated Learning Service for Gradient Boosted Decision Tables
Yifeng Zheng, Shuangqing Xu, Songlei Wang +2
Vertical federated learning (VFL) has recently emerged as an appealing distributed paradigm empowering multi-party collaboration for training high-quality models over vertically pa…
Metaverse: Security and Privacy Concerns
Ruoyu Zhao, Yushu Zhang, Youwen Zhu +2
The term "metaverse", a three-dimensional virtual universe similar to the real realm, has always been full of imagination since it was put forward in the 1990s. Recently, it is pos…
Secure Reversible Data Hiding in Encrypted Images Using Cipher-Feedback Secret Sharing
Zhongyun Hua, Yanxiang Wang, Shuang Yi +2
Reversible data hiding in encrypted images (RDH-EI) has attracted increasing attention, since it can protect the privacy of original images while the embedded data can be exactly e…
Nonlinear Chaotic Processing Model
Zhongyun Hua, Yicong Zhou
Designing chaotic maps with complex dynamics is a challenging topic. This paper introduces the nonlinear chaotic processing (NCP) model, which contains six basic nonlinear operatio…
