“…In this blind watermarking system, frequency masking is used to improve both the visual quality and robustness to attacks but its robustness is verified only against bit-rate decreasing and frame dropping. In [98], the authors proposed a watermarking scheme for MPEG-4 natural video objects in which both synchronization and watermark signals are embedded to enable fast synchronization recovery in the case of object manipulation. Lu et al in [99] designed a watermarking algorithm based on the concept of communications with side information for a MPEG-4 video object.…”

The illegal distribution of a digital movie is a common and significant threat to the film industry. With the advent of high-speed broadband Internet access, a pirated copy of a digital video can now be easily distributed to a global audience. A possible means of limiting this type of digital theft is digital video watermarking whereby additional information, called a watermark, is embedded in the host video. This watermark can be extracted at the decoder and used to determine whether the video content is watermarked. This paper presents a review of digital video watermarking techniques in which their applications, challenges and important properties are discussed, and categorizes them based on the domain in which they embed the watermark. It then provides an overview of a few emerging innovative solutions using watermarks. Protecting a 3D video by watermarking is an emerging area of research. The relevant 3D video watermarking techniques in the literature are classified based on the image-based representations of a 3D video in stereoscopic, depth-image-based rendering and multi-view video watermarking. We discuss each technique and then present a survey of the literature. Finally, we provide a summary of this study and propose some future research directions.

As an effective technology for copyright protection, digital watermarking has been applied in videos. Temporal synchronization is an important aspect for video watermarking. If synchronization is lost, the detector may fail in extracting the correct watermark. This paper proposes a temporal synchronous compressed MPEG-4 video watermarking scheme. This scheme utilizes DCT direct current coefficients to divide video into several scenes. Watermarks are embedded according to features of scenes. Bit rate control is introduced to ensure that watermark embedding does not increase the size of video. Drift compensation is employed to counteract the visual distortion in P-frames and B-frames caused by watermark embedding. Visual masking is exploited to enhance the invisibility of watermark. Experimental results show that the scheme has satisfactory ability in resisting the temporal synchronization attacks of frame deleting and frame inserting, therefore achieving well robustness.

“…Many works have been done at object level. Boulgouris et al [7], Lu and Liao [8], and Lie et al [9] chose to embed the watermark in the DCT domain. But these algorithms are not robust to segmentation error since watermarked DCT blocks on the mask boundary are very sensitive to mask or segmentation error.…”

An object-based video authentication system, which combines watermarking, error correction coding (ECC), and digital signature techniques, is presented for protecting the authenticity between video objects and their associated backgrounds. In this system, a set of angular radial transformation (ART) coefficients is selected as the feature to represent the video object and the background, respectively. ECC and cryptographic hashing are applied to those selected coefficients to generate the robust authentication watermark. This content-based, semifragile watermark is then embedded into the objects frame by frame before MPEG4 coding. In watermark embedding and extraction, groups of discrete Fourier transform (DFT) coefficients are randomly selected, and their energy relationships are employed to hide and extract the watermark. The experimental results demonstrate that our system is robust to MPEG4 compression, object segmentation errors, and some common object-based video processing such as object translation, rotation, and scaling while securely preventing malicious object modifications. The proposed solution can be further incorporated into public key infrastructure (PKI).
