Enhancing Real-World Adversarial Patches with 3D Modeling Techniques
share
Although many studies have examined adversarial examples in the real world, most of them relied on 2D photos of the attack scene; thus, the attacks proposed cannot address realistic environments with 3D objects or varied conditions. Studies that use 3D objects are limited, and in many cases, the real-world evaluation process is not replicable by other researchers, preventing others from reproducing the results. In this study, we present a framework that crafts an adversarial patch for an existing real-world scene. Our approach uses a 3D digital approximation of the scene as a simulation of the real world. With the ability to add and manipulate any element in the digital scene, our framework enables the attacker to improve the patch's robustness in real-world settings. We use the framework to create a patch for an everyday scene and evaluate its performance using a novel evaluation process that ensures that our results are reproducible in both the digital space and the real world. Our evaluation results show that the framework can generate adversarial patches that are robust to different settings in the real world.
