A region specific robust watermarking scheme based on singular value decomposition
Priyanka Singh, Suneeta Agarwal · 2012
Security breaches are increasing day by day as the technology is innovating and opening new doors. There are various counter measures to keep a check on them and one such method is the watermarking. Region based watermarking is the approach where an important area of the original image is selected to hide the secret information. This is done to make the watermarking more robust to the various attacks and retain the commercial value of the image as any damage to this region would result in deterioration of the value of the image. One such quad tree based approach to select the region of interest (ROI) and then to utilize the properties of the singular value decomposition (SVD) transform to hide the watermark is being proposed here. The robustness of the methodology against the various attacks is validated by the experimental results.
