Abstract

Digital watermarking is the process of embedding information into a digital signal. In this paper to improve the robustness, the hybrid DWT-SVD based algorithm is proposed for embedding and extracting process. The suggested method is performed by modification on singular value decomposition of images in Discrete Wavelet Transform (DWT) domain. Modification of the appropriate sub-bands leads to a watermarking scheme which favorably preserves the quality. The experimental result shows good robustness by using hybrid DWT-SVD method in comparison with DWT based watermarking algorithm using Haar wavelet.
