Robust Watermarking Scheme Based on Discrete Wavelet Transform and Visual Hided Scheme

Deepak Sharma*, Ankit Aggrawal, Ankit Gupta, Harshita Rai and Neha Singh

Digital watermarking is one of very popular mechanisms which is widely used for the copyright protection and data authentication of digital multimedia. This paper presents a robust copyright protection scheme based on discrete wavelet transform (DWT) and visual hided scheme (VHS). Unlike the traditional schemes, in our proposed scheme, the original image is modified by embedding the watermark into the original image. We use the visual hided scheme to construct watermarked image. In embedding 3 level DWT is applied on cover image and then embedding of watermark is performed using VHS technique after resizing the watermark image. In order to express the robustness and perceptibility of the presented watermark scheme experimental results shows the performance of proposed scheme based on parameters peak signal to noise ratio and resistance against various signal processing operations and attacks.
