Watermarking has been used time and again for authentication & security of Video. Digital watermarking refers to embedding watermarks in a multimedia documents and files in order to protect them from illegal copying and identifying manipulations. Watermarking is a promising solution to protect the copyright of multimedia data through Transcending, because the embedded message is always included...

We propose the application of optical watermarking to real moving objects like the faces of people who are walking. Optical watermarking technology uses spatially modulated light containing invisible watermarked data that irradiates real objects to make photographed data contain the embedded watermarking. We performed experiments where illumination containing time-sequential data embedded with ...

Digital data representation provides an efficient and fast way to access to information and to exchange it. In many situations though ownership or copyright protection mechanisms are desired. For still images and video, one possible way to achieve this is through watermarking. Watermarking consists of an imperceptible information embedded within a given media. Parallel Processing Watermarking E...

--Many watermarking methods for protecting the intellectual property right and authenticating multimedia data have been proposed in recent years. It is possible to guarantee the authenticity of data using readable and fragile watermarking. In this paper, we propose a visible watermarking technique using verifiable digital seal image that is based on the concept of fragile watermarking. Seal ima...

Digital watermarks have been proposed in recent literature as the means for copyright protection of multimedia data. In this paper we address the capability of invisible watermarking schemes to resolve copyright ownerships. We will show that rightful ownerships cannot be resolved by current watermarking schemes alone. In addition, in the absence of standardization of watermarking procedures, an...

The rapid growth of digital multimedia technologies brings tremendous attention to the field of digital watermarking. The owner or the distributor of the digital images can insert unique watermark into copies for different customers or receivers, which will be helpful to identify the source of illegal copies. Watermarking embeds a secret message into a cover multimedia data. In media watermarki...

With rapid growth in computer network and information technology, a large number of copyrighted works now exist digitally as a computer files, and electronic publishing is becoming more popular. These improvements in computer technology increase the problems associated with copyright enforcement and thus future developments of networked multimedia systems are conditioned by the development of e...

In this paper, an innovative watermarking scheme for audio signal based on genetic algorithms (GA) is proposed. Designing an optimal audio watermarking system is an open difficult issue since its two basic performance measures, i.e., imperceptibility and robustness. So, an optimal audio watermarking scheme needs to optimally balance both imperceptibility and robustness. In order to realize such...

The use of multimedia technology is growing every day, and it difficult time-consuming to provide allowed data while preventing secret information from being used without authorization. material that has been watermarked can only be accessed by authorized users. Digital watermarking a popular method for protecting digital data. embedding into actual the subject watermarking. This paper examines...

"Watermarking" is one method in which digital information buried a carrier signal; the hidden should be related to signal. There are many different types of watermarking, including traditional watermarking that uses visible media (such as snaps, images, or video), and signal may carrying watermarks. Any can tolerate noise, such audio, video, picture data, have watermark implanted it. A must abl...
