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.

Digital video is one of the popular multimedia data exchanged in the internet. Due to their perfectly replicable nature many illegal copies of the original video can be made. Methods are needed to protect copyrights of the owner and prevent illegal copying. A video can also undergo several intentional attacks like frame dropping, averaging, cropping and median filtering and unintentional attacks like addition of noise and compression which can compromise the owner information thereby denying authentication. In this paper, a robust Discrete Wavelet Transform (DWT)-based blind digital video watermarking scheme with scrambled watermarks based on scene changes has been proposed for authentication of digital video, which embeds different parts of a single watermark into different scenes of a video. The video watermarking algorithm is robust against the attacks of frame dropping, averaging and compression, which are considered as some of the common types of attacks applied particularly on the video and due to the use of DWT it can also withstand geometrical attacks making the watermark perceptually invisible. Furthermore, it allows blind retrieval of embedded watermark which does not need the original video. The proposed algorithm has been compared with an existing DWT based watermarking scheme and is found to exhibit better robustness.

“…Hartung et al [1] embedded spread-spectrum watermark into the MPEG-2 bitstream with drift compensation, but the capacity is reduced. Arena et al [2] watermarked the MPEG-2 video using interleaved coding. The differential energy watermark method has been extended to video from still images by watermarking the I-frames of an MPEG stream as in [3].…”

Abstract-A novel grayscale watermark pre-processing and a robust video watermarking algorithm for the emerging video coding standard H.264/AVC are proposed in this paper for the copyright protection application. This algorithm can insert grayscale watermark patterns such as detailed trademarks or logos into the low bit-rate H.264/AVC videos in the compressed domain with good robustness and high capacity. The marked video sequences maintain good visual quality and the same overall consuming bit-rate. The proposed algorithm can robustly survive transcoding process and common signal processing, such as bitrate reduction, Gaussian filtering and contrast enhancement.
