Chengxin Zhao, Hefei Ling, Sijing Xie, Han Fang, Yaokun Fang, Nan Sun

TL;DR
This paper introduces SSyncOA, a watermarking method that aligns watermarks with objects in images to resist cropping-paste attacks involving rotation, scaling, and translation, outperforming existing techniques.
Contribution
The paper proposes a novel self-synchronizing object-aligned watermarking approach that normalizes object features to resist complex cropping-paste distortions.
Findings
Outperforms state-of-the-art watermarking methods in resisting cropping-paste attacks.
Effectively normalizes rotation, scaling, and translation distortions.
End-to-end optimized model demonstrates superior robustness in experiments.
Abstract
Modern image processing tools have made it easy for attackers to crop the region or object of interest in images and paste it into other images. The challenge this cropping-paste attack poses to the watermarking technology is that it breaks the synchronization of the image watermark, introducing multiple superimposed desynchronization distortions, such as rotation, scaling, and translation. However, current watermarking methods can only resist a single type of desynchronization and cannot be applied to protect the object's copyright under the cropping-paste attack. With the finding that the key to resisting the cropping-paste attack lies in robust features of the object to protect, this paper proposes a self-synchronizing object-aligned watermarking method, called SSyncOA. Specifically, we first constrain the watermarked region to be aligned with the protected object, and then…
