Paper Abstract
In this paper, we propose an improved autocorrelation function
(ACF) based watermarking. The autocorrelation function based
watermarking has been known to be one of the effective
watermarking schemes that are resilient to geometric transform
attacks. In this watermarking scheme, both the peaks in the
autocorrelation function of a marked image and the embedded
watermark should survive after various attacks. Generally, the
autocorrelation peaks are less robust than the actual watermark
signal. The main focus of this paper is the improvement of the
robustness of the peaks in an autocorrelation function. Since an
original image and the detector structure are available at the
embedding time, instead of simple addition of a watermark to an
image, the watermark embedder analyzes the original image and uses
this information actively during the embedding process so that the
marked image has higher periodic autocorrelation peaks. The
proposed watermarking scheme has higher robustness than a
conventional ACF based watermarking against geometric attacks that
are combined with removal attacks.
