Core Concepts
SATBA proposes an imperceptible backdoor attack using spatial attention, overcoming limitations of existing methods and ensuring high attack success rate.
Abstract
Backdoor attacks on DNNs pose a serious threat to AI security.
Existing backdoor attacks suffer from detectability and feature loss issues.
SATBA utilizes spatial attention and a U-net model to create imperceptible triggers.
Extensive experiments demonstrate high attack success rate and stealthiness of SATBA.
SATBA shows resistance to backdoor defenses like Neural Cleanse and AEVE.
The attack maintains high stealthiness and effectiveness across different datasets and models.
Stats
"The results demonstrate that SATBA achieves high attack success rate while maintaining robustness against backdoor defenses."
"The poisoned images created by SATBA appear more natural and closely resemble the clean image."
"Our proposed attack achieved excellent scores in all similarity metrics, including the highest PSNR and lowest MSE values for all three datasets."
Quotes
"SATBA presents a promising approach to backdoor attack, addressing the shortcomings of previous methods and showcasing its effectiveness in evading detection and maintaining high attack success rate."
