“…Instead of converting the I-frames from RGB into YUV, the authors use the YCbCr color space to realize the transparency objective. This work was subsequently enhanced by the same authors, who focused on capacity and security features [24]. The capacity feature is realized by manipulating the original video at the bit level, while the security feature is realized by encrypting the watermark prior to hiding it.…”

In recent years, video watermarking has emerged as a powerful technique for ensuring copyright protection. However, ensuring the lowest level of distortion, high transparency and transparency control, integrity of the watermarked video, and robustness against attacks that can be applied to destroy the embedded watermark are important properties that should be satisfied in a watermarking system. In this paper, we propose a video watermarking system that hides a watermark in both the visual and audio streams to ensure the integrity of the watermarked video. Specifically, we propose the moving block detection (MBD) algorithm for hiding the watermark in the moving parts of the original visual stream of the video. The MDB algorithm ensures that a minimal amount of distortion is caused by embedding the watermark. The MBD uses entropy to find the moving parts of the visual stream to hide the watermark. The process of hiding in the visual stream is performed using DWT to ensure both transparency and resistance against attacks. We employ the power factors of DWT to control the level of transparency. In addition, we propose the silence deletion algorithm (SDA), which generates a pure original audio stream by removing the noise from the original audio stream to form the hiding place of the watermark within the audio stream. DCT is employed to hide the watermark within the pure original audio stream to ensure resistance against attacks. Under a threat model, which includes bilinear, curved, and LPF geometric attacks and compression and Gaussian noise nongeometric attacks, the experimental results demonstrated that the proposed system outperformed four similar systems: keyframe-, I-frame-, spread-spectrum-, and LBS-based systems.

“…Test experiments, using various kinds of attacks showed strong resistance compared with a method that embedding in all frames as well as high transparency with satisfied values of PSNR. The same authors developed the previous study focusing on the capacity of hiding and more security [9]. They also used DWT transform in the process of hiding where the watermark was embedded in the key-frames that were included in each spot.…”

Watermarking techniques are modern and strong methods of copyright protection for authors and companies as well as for ensuring the authority and identification. They hide the company's motto or policy of using for any digital content that exchanged via the internet. Various requirements are needed to embed the watermark in digital media like transparency, capacity, security and robustness against attacks. However, applying watermark on video, with visual and audio stream parts, is still a resource of concern for scientists and interested people to ensure the integrity of the whole video and guarantee that no manipulation was made on the video. In this research, a system is presented for video copyright protection taking into account its integrity and achieving all requirements in watermarking. The system will embed the watermark in both audio and visual streams allowing the transparency control in the watermarked video. Comparing to previous works, our experimental results showed better performance under the terms of robustness against attacks.

In this paper a novel blind watermarking technique for color images using DCT has been proposed. Inproposed technique cover image is decomposed into 3 planes, namely R, G, B and for watermarking B plane is selected. B plane is divided into blocks of size 8×8. DCT is applied to each 8×8 sized block and middle frequency coefficients are selected for embedding watermark. Finally binary watermark is embedded into each8×8DCT block by adjusting middle frequency coefficients DCT(4,3) and DCT(5,2). Experimental results shows that the proposed technique is imperceptible as well as robust against wide variety of attacks like Gaussian noise, Salt -pepper noise, Gaussian filter, Median filter, Histogram equalization etc and achieves average PSNR as 58.90 dB. Proposed technique does not require cover image at the time of watermark extraction then too watermark is extracted completely and better than its counterparts available.
