Watermarking is a technique, which is used in protecting digital information like image, video and audio as it provides copyrights and ownership Audio watermarking is more difficult than image watermarking than image watermarking due to the dynamic supremacy of hearing capacity over the visual field. Digital watermarking is a technique by which copyright information is embedded into the host si...

bstract. Digital video watermarking has attracted a great deal of esearch interest in the past few years in applications such as digital ngerprinting and owner identification. The H.264/AVC (advanced ideo coding) standard is the latest and most advanced video codng standard, but to this date, very few watermarking schemes have een designed for it. This is mainly due to its complexity and comres...

Spread spectrum has been used as a technique for secure communications for a long time. For still image watermarking, spread spectrum has been the method of choice for some time. In this paper we argue that spread spectrum in the form of CDMA has a more natural application in the watermarking of uncompressed digital video. The reason for this sentiment is that digital video, by virtue of its ti...

Digital watermarking was introduced during the last decade as a complementary technology to protect digital multimedia data. Watermarking digital video material has already been studied, but it is still usually regarded as watermarking a sequence of still images. However, it is well-known that such straightforward frame-by-frame approaches result in low performance in terms of security. In part...

Video watermarking is usually considered as watermarking of a set of still images. In frame-by-frame watermarking approach, each video frame is seen as a single watermarked image, so collusion attack is more critical in video watermarking. If the same or redundant watermark is used for embedding in every frame of video, the watermark can be estimated and then removed by watermark estimate remod...

This paper presents an evaluation for a wavelet-based digital watermarking technique used in estimating the quality of video sequences transmitted over Additive White Gaussian Noise (AWGN) channel in terms of a classical objective metric, such as Peak Signal-to-Noise Ratio (PSNR) without the need of the original video. In this method, a watermark is embedded into the Discrete Wavelet Transform ...

Many video watermarking algorithms have been developed over the years to provide authenticity of video contents. The major challenges were to maintain the perpetual quality of the video and also sustaining the imperceptibility of watermark to Human Visible Systems (HVS). With rapid growth of online streaming and other video applications compression of video contents became very much essential f...

A major class of image and video watermarking algorithms, i.e. content-based watermarking, is based on the concept of Human Visual System (HVS) in order to adapt more efficiently to the local characteristics of the host signal. In this paper, a content-based video watermarking scheme is developed and the concept of entropy masking effect is employed to significantly improve the use of the HVS m...
