基于毫米波（mmWave）的人类活动识别（HAR）系统近年来出现，由于其更好的隐私保护和更高的分辨率感测。然而，这些系统容易受到对抗性攻击。在这项工作中，我们提出了一种通用的针对性攻击方法毫米波基于HAR系统。特别是，提前生成通用扰动，可以将其添加到新出现的毫米波数据中以欺骗HAR系统，使其输出我们想要的标签。我们使用公共mmWave数据集验证了我们提出的攻击。我们证明了我们提出的通用攻击的有效性，攻击成功率超过95%。
Millimeter wave (mmWave)-based human activity recognition (HAR) systems have emerged in recent years due to their better privacy preservation and higher-resolution sensing. However, these systems are vulnerable to adversarial attacks. In this work, we propose a universal targeted attack method for mmWave-based HAR system. In particular, a universal perturbation is generated in advance which can be added to new-coming mmWave data to deceive the HAR system, causing it to output our desired label. We validate our proposed attack using a public mmWave dataset. We demonstrate the effectiveness of our proposed universal attack with a high attack success rate of over 95%.
