Adversarial Laser Spot: Robust and Covert Physical Adversarial Attack to DNNs

Most existing deep neural networks (DNNs) are easily disturbed by slight noise. As far as we know, there are few researches on physical adversarial attack technology by deploying lighting equipment. The light-based physical adversarial attack technology has excellent covertness, which brings great security risks to many applications based on deep neural networks (such as automatic driving technology). Therefore, we propose a robust physical adversarial attack technology with excellent covertness, called adversarial laser point (AdvLS), which optimizes the physical parameters of laser point through genetic algorithm to perform physical adversarial attack. It realizes robust and covert physical adversarial attack by using low-cost laser equipment. As far as we know, AdvLS is the first light-based adversarial attack technology that can perform physical adversarial attacks in the daytime. A large number of experiments in the digital and physical environments show that AdvLS has excellent robustness and concealment. In addition, through in-depth analysis of the experimental data, we find that the adversarial perturbations generated by AdvLS have superior adversarial attack migration. The experimental results show that AdvLS impose serious interference to the advanced deep neural networks, we call for the attention of the proposed physical adversarial attack technology.
