In our digital society, the major source of communication is digital media such as images, video, audio or text. So impersonate and copyright protection of digital content remains an indispensable problem across the globe. To deal with this problem, digital watermarking has become advantageous solution for providing ownership of digital content. In this paper we have developed a robust DCT base...

1 M. Tech Student 2 M. Tech (Ph. D) 1,2 Department of Computer Engineering 1,2 Galgotias University, Greater Noida, India Abstract— Digital watermarking is one of the proposed solutions for copyright protection of multimedia data. A watermark is a form of image or text that is impressed onto paper, which provides evidence of its authenticity. A digital watermark is digital data embedded in some...

Digital watermarking is an efficient method for copyright protection for text, image, audio, and video data. This paper presents a new image watermarking method based on integer-to-integer wavelet transforms. The watermark is embedded in the significant wavelet coefficients by a simple exclusive OR operation. The method avoids complicated computations and high computer memory requirements that ...

Digital watermarking is one of the proposed solutions for copyright protection of multimedia data. This technique is better than Digital Signatures and other methods because it does not increase overhead. Digital Watermarking describes methods and technologies that hide information, for example a number or text, in digital media, such as images, video or audio. The embedding takes place by mani...

Watermarking is the process of embedding a watermark into host signal that can be in the form of Audio, Video, and Image .The watermark can be embedded as Logo, Text, and String. The main objective of embedding watermark is to protect the data from unethical hackers over Internet. This watermarking scheme can be embedded in different domains which can be referred as Spatial and Transform domain...

Watermarking is done in digital images for authentication and to restrict its unauthorized usages. Watermarking is sometimes invisible and can be extracted only by authenticated party. Encrypt a text or information by public – private key from two fuzzy matrix and embed it in image as watermark. In this paper we proposed two fuzzy compositions Product-Mod-Minus, and Compliment-Product-Minus. Em...

With the tremendous development of the Internet, it has become desirable to distribute text documents electronically. However, commercial publishers may be reluctant to offer valuable digital documents online for the fear that they will be re-transmitted or copied illegally. To address this problem, we propose a robust watermarking technique, whereby electronic text documents are fingerprinted ...

The pivotal purpose of this paper is to introduce a scheme for watermarking of digital images in which one can embed some secret text in an encrypted manner and a secret image more than once in the host image, starting from different pixel positions based on the key. All this can be done without violating any of the desirable properties of the standard watermarking algorithms. The key plays a p...

One way for copyright protection is digital watermarking. Digital watermarking is the process of embedding information regarding the authenticity or the identity of the owners into a image or any piece of data. Digital watermarking has been classified into two types :Visible and Invisible Watermarking. In visible digital watermarking, the embedded information is visible. Typically, the informat...

Embedding a hidden stream of bits in a file is called Digital Watermarking. The file could be an image, audio, video or text. Nowadays, digital watermarking has many applications such as broadcast monitoring, owner identification, proof of ownership, transaction tracking, content authentication, copy control, device control, and file reconstruction (Cox et. al., 2008). In literature, the host f...
