REVAMP: Automated Simulations of Adversarial Attacks on Arbitrary Objects in Realistic Scenes
This tool addresses the problem of evaluating adversarial robustness for researchers and practitioners in AI security, though it is incremental as it builds on existing digital attack methods by adding simulation capabilities.
The authors tackled the challenge of transferring adversarial attacks from digital to physical realms by introducing REVAMP, a Python library that simulates realistic environmental factors to generate physically plausible adversarial objects, enabling real-time mis-classification demonstrations.
Deep Learning models, such as those used in an autonomous vehicle are vulnerable to adversarial attacks where an attacker could place an adversarial object in the environment, leading to mis-classification. Generating these adversarial objects in the digital space has been extensively studied, however successfully transferring these attacks from the digital realm to the physical realm has proven challenging when controlling for real-world environmental factors. In response to these limitations, we introduce REVAMP, an easy-to-use Python library that is the first-of-its-kind tool for creating attack scenarios with arbitrary objects and simulating realistic environmental factors, lighting, reflection, and refraction. REVAMP enables researchers and practitioners to swiftly explore various scenarios within the digital realm by offering a wide range of configurable options for designing experiments and using differentiable rendering to reproduce physically plausible adversarial objects. We will demonstrate and invite the audience to try REVAMP to produce an adversarial texture on a chosen object while having control over various scene parameters. The audience will choose a scene, an object to attack, the desired attack class, and the number of camera positions to use. Then, in real time, we show how this altered texture causes the chosen object to be mis-classified, showcasing the potential of REVAMP in real-world scenarios.
