Efficient Approach of Digital Video Watermarking Using LDPC

The most important issues in video watermarking are invisibility of the watermark and the resilience of watermarking to attacks. The area of video watermarking has focused primarily on the problem of robustness to geometric attacks, while discounting the problem of more sophisticated attackers. So to improve the robustness of watermark for A new digital watermarking algorithm, for based on LDPC coding ,to embedded the watermark in videos that insert information in the side view, unlike the regular approaches that insert on the frames. Video watermarking technology has applied image watermarking technology to individual frames of a video. The implemented watermarking system operates in the spectrum domain where a subset of the discrete wavelet transform (DWT) coefficients is modified by the watermark without using the original image during watermark extraction. The quality of watermark is evaluated by taking into account the trade-off between the chip-rate and the rate of LDPC codes.
