Hemachandran Department of Computer Science, Assam University, Silchar, Assam, India ABSTRACT The growth of number of users excessing the internet has increase enormously in past decade, so a need has arrive to protect the digital content. Digital watermarking is an art of hiding information into digital content. Visible watermark are used to discourage the unauthorized usage of the digital image. If a visible watermark is embedded in the texture region of an image, it didn’t cause any degradation in the perceptual quality of the image, to hide image in the high texture we use variance, Variance of the image is higher in the high texture area of the image block. Using this concept we developed a scheme to insert the watermark in the high texture area using Discrete Fourier Transform (DFT). Experimental results show the scheme is able to achieved high PSNR value of the watermarked image and SSIM suggested that the watermarked image is similar that of the original image. Keywords: Visible watermarking, Variance, PSNR, DFT, SSIM. I. INTRODUCTION Digital watermark is an art of putting some information for the protection of digital media from unauthorized uses. As of late the extraordinary development of internet has increase concerned over the authentic use of digital data moreover digital data can also be duplicated and distributed without the knowledge of the digital media owner. Though cryptography can be used to prevent the unauthorized uses by making the content of digital meaning less using a key, but there is a problem with cryptography, once the content of the digital media is decrypted the owner cannot trace the duplication and distribution of its media content. Digital watermarking come in handy for the copyright protection of the digital data. Like steganography digital watermarking is adding some king of owner information along with the digital content. The main different between digital watermark and steganography is in term of robustness. Steganography is a secret mean of communicating between two parties without the knowledge of the third party, once the third party came know about the secret information steganography fail. Not much thought about the robustness is given in steganography but how the information is to be hidden is given the priority in steganography. One more point that distinguishes digital watermark from steganography is the hidden message, in case of steganography the hidden message has nothing to do with the cover image. In Digital watermark, robustness, which mean the ability of detecting the hidden information or watermark after common image processing operation, is the main requirement of digital watermark. Robustness is one of the basic requirement of digital image watermarking. Other than robustness, imperceptibility, capacity and security are also the basic requirement of digital watermark. Imperceptibility or fidelity refer to the perceptual similarity between the original cover work and watermarked image or in other word addition of watermark should hampered or degrades the quality of the cover work. Capacity or data payload mean the amount of information bit that can be embedded onto a cover work. Lastly security refer
