Abstract

Invisible digital image watermarking is one of the most effective and protected methods for obviating prohibited copying of digital media. Several research papers have explored watermarking techniques in various domains. In this paper, we carried out experimental analysis to assess the robustness and performance analysis of popular, efficient, secure, and robust invisible digital image watermarking techniques using singular value decompositions (SVD), discrete cosine transform (DCT), discrete wavelet transform (DWT). The experimental and theoretical analysis of different comparative watermarking algorithms in terms of quality of watermarked images and the capability to protect the embedded watermarks in toughest situations demarcates the conclusion of the paper.
