Fast and Effective Overwrite Attack Against DNN-based Image Watermarking Models

Deep neural network (DNN)-based image watermarking models have been widely recognized as an effective way to manage the huge amount of AI-generated images. However, the vulnerability of such models to different forms of adversarial attacks has been a critical concern. Among the existing forms of attacks in the literature, image-dependent attacks cannot launch real-time attacks on a large number of watermarked images, because they need to train …
