ROBUSTNESS OF IMAGE AGAINST AMBIGUITY ATTACK FOCUSING ON SINGULAR VALUE DECOMPOSITION AND REDUNDANT DISCRETE WAVELET TRANSFORM WATERMARKING TECHNIQUES

Digital image watermarking technique is being used for confirmation of proprietorship and copyright protection. A novel resilient image watermarking approach that relies on the Redundant Discrete Wavelet Transform and Singular Value Decomposition techniques for these applications were first suggested by Khoo and Makbol (2013). In this research, we provide two ambiguity attacks on this approach to show that it is ineffective for robustness concerns including transaction monitoring, proprietor identification, and ownership assurance.
