An Upgraded Approach for Robust Video Watermarking Technique Using Stephens Algorithm?

Digital data is easily available in the form of images and videos, over the internet. Because of their digital nature, multimedia data can be duplicated, modified, transformed and diffused very easily. The growth of internet is so vast that any data can be easily transferred to the other person in just a single click. In video watermarking, protection of multimedia data becomes increasingly prominent. So, recent development of digital watermarking can solve this problem. Our objective is to implement an effective algorithm for robust video watermarking. In this thesis, we have studied and implemented an algorithm using Matrix Laboratory which gives better result than previously used techniques. Techniques used in video watermarking are discussed with the literature survey and then the shortcoming is analyzed and as conclusion proposal for new points for hiding watermark in video is given. So there is need for new robust technique which will be able to hide watermark at such place in frames so cannot be extracted easily and provide more security over video watermarking old techniques. For this as a new research in same field an algorithm with efficient point finding will be proposed to hide watermark in video to provide robust and secured watermarking. I have implemented new robust techniques gives the better result. I analyzed the results on the basis of different parameters (Peak Signal to Noise Ratio, Mean Square Error, Bit Error Rate).
