Authors : A. Lakshmi Priya and S. Letitia

Abstract: The main intention of a majority of the researches is paying attention to digital image watermarking technology is to improve the robustness to attacks. In this paper a new dual watermarking technique using singular value decomposition and improved Arnold transform is used to balance the trade-off between imperceptibility and robustness of the watermarks. In the proposed technique the secondary watermark is scrambled using improved Arnold and embedded into primary watermark the resultant new image is used as watermark for the Host image. The insertion and extraction of the watermarks are performed using the discrete wavelet transform, discrete cosine transform and singular value decomposition. This algorithm enhances the visual imperceivability of the watermarked image and robustness against various removals and geometric attacks. Numerous experiments have been performed; the numerical analysis demonstrates the improvement in embedding capacity, visual imperceptibility and watermark robustness compared with subsisting methods.
