Comparative Analysis of Digital Image Watermarking Techniques - SVD based Algorithms in Different Wavelet Domains
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2014, Vol 5, Issue 6
Abstract
The aim of digital watermarking is to hide some secret information or logo into the multimedia content for protecting the content from unauthorized access or illegal use. Digital image watermarking is a promising domain for various applications, for example, ownership identification, copy protection, authentication, broadcast monitoring, tamper detection etc. In this paper we are going to discuss two different techniques with our proposed one which all are based on SVD but in different wavelet domains that is RDWT, DWT and IWT. Comparison between these techniques is performed on the basis of their computation time, watermarked image and extracted watermark fidelity, and the most important robustness against attacks on the basis of PSNR and correlation coefficient. The graphical representation shows that the proposed algorithm based on IWT-SVD works well than the other two.
