The digital watermarking is a field of information hiding which hide the crucial information in the original data for protection illegal duplication and distribution of multimedia data. The image watermarking techniques may divide on the basis of domain. Today, in the market, the protection of copyrighted material has become a new challenge, as the importance of the internet is increasing day by day in information acquisition. For protection of copyright material watermarking is introduced. Digital Watermarking is the process to authenticate user files by embedding and hiding digital code behind an image, text, audio and video file With the rapid development and wide use of Internet, information transmission faces a big challenge of security. Digital watermarking is a technique of data hiding, which provide security of data. The process of embedding additional data along with the digital audio, images and video is called digital watermarking. This paper classified various watermarking techniques and there comparisons. It starts with overview, classification, features, techniques, application and performance measuring of watermarking and a comparative analysis of watermarking techniques. Keywords:- Digital watermarking I. INTRODUCTION A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as an audio, video or image data. It is typically used to identify ownership of the copyright of such signal. "Watermarking" is the process of hiding digital information in a carrier signal; the hidden information should, [1] but does not need to, contain a relation to the carrier signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Watermarking is a technique used to hide data or identifying information within digital multimedia. Our discussion will focus primarily on the watermarking of digital images, though digital video, audio, and documents are also routinely watermarked. Digital watermarking is becoming popular, especially for adding undetectable identifying marks, such as author or copyright information. The digital watermarking process embeds a signal into the media without significantly degrading its visual quality. Digital watermarking is a process to embed some information called watermark into different kinds of media called Cover Work. Digital watermarking is used to hide the information inside a signal, which cannot be easily extracted by the third party. Its widely used application is copyright protection of digital information. Watermark is perceptible or imperceptible identification code which uniquely identifies ownership of an image . It is permanently embedded into the host image. The embedded watermark may be pseudo- random binary sequence, chaotic sequence, spread spectrum sequence or binary/gray scale image. Such watermarks are used for objective detection using correlation measures. Binary or gray image is meaningful and is used for subjective detection. The examples of this type of watermark include date, serial number, logo or any other kind of identification mark Figure 1: Original image with watermarked image RESEARCH ARTICLE OPEN ACCESS
