Abstract

Abstract:- In this digital world, Internet use has become prevalent. For all web users, information or data is a primary tool. Today it has become popular for accessing and exchanging media files such as images, audio, videos and copyrighted documents on public networks such as the Internet through Facebook, Twitter, email, forums, blogs, etc. The Internet paves the way for a wide range of multimedia content, such as text, images, audio, and video to be distributed. With the use of sophisticated signal/image processing algorithms, manipulations and duplication of audio, images, videos and documents are much easier. Therefore, content authentication has become an imminent and significant issue through encryption and resistance to general attacks such as noise, compression, and geometry. Data protection has become a big problem. Even the means through which the data is transmitted are not reliable. Therefore, some methods are required to protect media content. Digital watermark is one of the techniques that plays a key role in data protection. In this article, we proposed an adaptive digital watermark technique through the color and texture characteristics of an image through Arnold transform using DWT. In this research, we took entropy as one of the statistical parameters to decide the watermark based on color or texture. The two most popular attributes of the watermark, which are imperceptibility and robustness, decide the success of watermark algorithms. Experimental results in different cover images and under bindings such as mean attack, salt and pepper noiseand geometric attack using PSNR and NCC, clearly demonstrate the robustness of the proposed algorithm.Keywords: Entropy, DWT, Attack, Adaptive Watermarking
