English(EN) Position Matters: Feature Inversion Attacks in ViT Split Inference with Token Reduction and Shuffling

新的 SARA 攻击可从 ViT 嵌入中重建图像,绕过隐私措施

研究人员开发了一种名为 SARA 的新特征反演攻击,该攻击可以从分割推理系统中传输的 Vision Transformer (ViT) 嵌入中重建输入图像。尽管采用了旨在增强隐私的 Token 打乱和缩减技术,SARA 仍证明了位置信息保留在嵌入中。该攻击包括预测 Token 位置、恢复空间布局以及使用掩码自动编码器重建缺失的嵌入。虽然 Token 缩减提供了一定的保护,但信息泄露仍然显著。提出的防御措施包括移除位置嵌入并通过知识蒸馏调整 Transformer 块,这在保持下游任务准确性的同时,大大降低了攻击性能。 AI

影响 凸显了使用 ViT 的分割推理系统中潜在的隐私漏洞,需要更强的防御措施。
