Digital video is becoming popular more than ever due to the widespread of video-based applications. However, a byproduct of such popularity is the worldwide unauthorized copying and distribution of digital video. Digital watermarking has been proposed in the last decade as a solution to prevent unlawful and malicious copying and distribution of digital media by embedding unnoticeable information (called watermark) into the media content. In this study, a robust and heuristic algorithm based on DWT for video watermarking is presented. With the aim of providing the security of the proposed method, the watermark is encrypted first, then the color video is partitioned into units of fixed length. Embedding process is followed by detecting the key-frames in each shot. In order to make the watermark imperceptible, RGB video stream is converted into YCbCr color space. The luminance layers are chosen to embed the watermark and the chrominance layers are left unchanged. Eventually, by using a multiplicative hiding method, watermark image is embedded into frequency components of frames. Using this method a large amount of data can be hidden in a video. Furthermore, the presented method maintains a good transparency of video stream meanwhile resists the watermark against a variety of attacks including geometric attacks such as rescaling, rotation, and nongeometric attacks like Gaussian noise, salt & pepper noise, speckle noise, median & low-pass filtering, blurring, JPEG and MJPEG compression.

“…Among them image and video watermarking are two important areas that has attracted several researchers ( [33], [21]). Methods for embedding watermark information may vary between types of media, but the basis of these methods remain more or less same.…”

The amount of information created in the current era of information explosion is increasing in a overwhelming fashion. This increase in content has increased the awareness to protect the intellectual property. This paper presents one such method to protect Video content. The proposed watermarking hybrid scheme combines visual cryptography and wavelets to create a nested watermark, which is embedded into the raw uncompressed video signal using geometric warping technology. A block selection algorithm is used to select relevant area for embedding so as to improve robustness. The experimental resultsshowed that the proposed system shows significant improvement in terms of capacity and robustness against various attacks.

Regardless of the application, all these techniques have the common goal of protecting digital signal.…”

Advancement in communication medium is producing large volume of digital information which needs to be protected. Watermarking is a technique that is used to hide secret signal into digital signal in a manner that does not reduce overall quality of the original signal. In relation to digital image watermarking, another area that is drawing attention is the multiple watermarking, where more than one watermark is embedded into single multimedia object. M ultiple watermarks are normally proposed as a method to provide extra security to an image by embedding two or more secret messages into the cover image. In the present research work, the concept of multiple watermarking is used to hide both copyright and authentication information into a color image. For this purpose a wavelet transformation based on texture properties and secret sharing us ing visual cryptography is used. Experimental results indicate that the proposed watermarking scheme is highly robust and does not degrade the original signal.
