Paper Abstract

In this paper a new attack aimed at DM-QIM watermark detection and extraction is proposed, based on known histogram-based attacks against non-dithered QIM algorithm. Key recovery results obtained during proposed attack shows that for a sets of watermarked images it is possible to outperform known watermark detection attacks proposed for DM-QIM in case if non-local image statistics is utilized. Also several known techniques for secure key synchronization are recommended to improve robustness of existing DM-QIM robustness against proposed attack.
