Evaluating Transfer-based Targeted Adversarial Perturbations against Real-World Computer Vision Systems based on Human Judgments

View CodeNotebook

Computer vision systems are remarkably vulnerable to adversarial perturbations. Transfer-based adversarial images are generated on one (source) system and used to attack another (target) system. In this paper, we take the first step to investigate transfer-based targeted adversarial images in a realistic scenario where the target system is trained on some private data with its inventory of semantic labels not publicly available. Our main contributions include an extensive human-judgment-based evaluation of attack success on the Google Cloud Vision API and additional analysis of the different behaviors of Google Cloud Vision in face of original images vs. adversarial images.
