Title
Semi-blind Image Watermarking Using High Frequency Band Based on DWT-SVD
Abstract
With the fast development in computer network and multimedia technology, digital data (such as image, video, audio or text) are stored, transmitted and distributed through internet without any loss or damage of content. Digital image watermarking is use for the protection of digital data from the illegal manipulations. Watermarking not only allow user to access, view and interpret the image but also protects the ownership of the content, as protection is a crucial area. In this paper, a new semi-blind composite image watermarking algorithm based on DWT-SVD that is robust against various attacks is proposed. We obtained four different frequency images using DWT and IDWT transform. Watermark is embedded in high frequency sub-band by modifying the values of Singular Value Decomposition (SVD). Scaling factor is used to improve. Various experimental results demonstrate that proposed algorithm is able to withstand under various attack.
