Let the chirp coded signal be given by the function h ( t ), then the watermarking process is described by the equation s t = a bh t h t ∞ + n t n t ∞ and the coefficients a > 0 and 0 < b < 1 determine the amplitude and the SNR of s where a = n t ∞. (CSE) University College of Engineering Punjabi University, Patiala, Punjab, India Brahmaleen K. Sidhu Assistant Professor University College of Engineering Punjabi University, Patiala, Punjab, India ABSTRACT The low-frequency components of the audio signal have been selectively embedded with watermark image data making the watermarked audio highly imperceptible and robust. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Reversible watermarking enables the embedding of useful information in a host signal without any loss of host information. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. Watermarking is classified as fragile or robust based on the ability of the embedded watermark to withstand attacks on images. It splits the watermark into two shares using (2, 2)- threshold Visual Cryptography Scheme (VCS) with Adaptive Order Dithering technique and embeds one share into high textured subband of Luminance channel of the color image. The image has been extended by any other person now he is owner of image 4. The low-frequency components of the audio signal have been selectively embedded with watermark image data making the watermarked audio highly imperceptible and robust. 2 DIGITAL WATERMARKING TECHNIQUES 2.1 Digital Watermarking Systems Digital watermarking system consists of two main components: watermark embedder and watermark detector, as illustrated in Figure 2-1.
