Time Is All It Takes: Spike-Retiming Attacks on Event-Driven Spiking Neural Networks

Yi Yu, Qixin Zhang, Shuhan Ye +6

Spiking neural networks (SNNs) compute with discrete spikes and exploit temporal structure, yet most adversarial attacks change intensities or event counts instead of timing. We st…

StegaVAR: Privacy-Preserving Video Action Recognition via Steganographic Domain Analysis

Lixin Chen, Chaomeng Chen, Jiale Zhou +2

Despite the rapid progress of deep learning in video action recognition (VAR) in recent years, privacy leakage in videos remains a critical concern. Current state-of-the-art privac…

Backdoor Attacks against No-Reference Image Quality Assessment Models via a Scalable Trigger

Yi Yu, Song Xia, Xun Lin +4

No-Reference Image Quality Assessment (NR-IQA), responsible for assessing the quality of a single input image without using any reference, plays a critical role in evaluating and o…
