Abstract: Abstract Watermarking is a process of secret information (watermark) insertion in the digital image, which later on helps in finding out the correct owner of that image. The insertion of watermark’s singular values into the host image provide a high value of capacity, robustness and imperceptibility but the scheme remain vulnerable towards false positive attacks. Alternatively, insertion of watermark’s principle components into the host image make the scheme secured towards security errors but it also reduces the robustness and imperceptibility of the scheme. The exact recovery of this information becomes even more difficult after attacks because attacks change the information even further. This eventually leads to low imperceptibility and robustness of scheme. In general, the optimization of embedding strengths for image watermarking focuses on the maximization of both imperceptibility and robustness equally. In doing so, often, imperceptibility suffers as it gets degraded beyond a certain limit (
