Invisible Video Multiple Watermarking Using Optimized Techniques

According to time, so many researches have been proposed on invisible multiple watermarking. Basically, invisible video watermarking is the technique to hide relevant information into another host image, audio, text, and video. In this paper, invisible watermark is embedded by using DWT, LSB, DCT and Mojette. These techniques are based on some numeric parameters like PSNR (peak signal to noise ratio), RMSE (root mean square error), NC (normalized correlation) and MSE (mean square error). Various attacks are applied on the watermarked video and watermarking extraction process should be done to recover watermark. Then compare the recover watermark with an original watermark. A different watermark is embedded in a cover video, which is difficult for an attacker to hack digital contents. Comparative analysis of these three techniques also are used based on different type of scenarios should be used.
