This watermarking approach is based on the additive spread spectrum way and periodic watermark concept that make it robust. Objective of this work is to protect the piracy of video files. Some time, many illegal copies of videos are found on street market or on the internet before their official release. During copying or after copying the pirate may distort the video by scaling, rotation, translation etc. In this paper, a deterrent system has been proposed which is robust enough against the distortion and can identify the pirate, by embedding a payload into original video that consist the time stamp of video playback. Many experiments are done to prove that the proposed scheme fulfil the invisibility, real time processing and robustness requirements against distortion. Keywords: additive spread spectrum, distortion, real time, piracy deterrence, periodic watermark, DCT 1. Introduction Piracy of video has become a problem due to use of internet services or storage devices to share it. In most cases the video piracy takes place when it is transmitted from one place to another. Now a day’s digital video files are used very frequently for entertainment, learning and information sharing so it required protection against copyright and illegal copying. In copyright protection system a secret message and logo by owner is inserted into a digital media file without affecting its originality. As an ownership problem arises, that who is the original owner then the embedded message is extracted and the original owner can be identified. As a method of copyright protection, digital video watermarking [1-2] has recently emerged as a significant field of interest and a very active area of research. In watermarking a secret message is embedded into a multimedia files and this secret message is known as watermark or digital signature such that the watermark can be detected or extracted later to make an assertion about the object. Multimedia file may be an image, audio or video. Watermarking techniques should fulfil the all required necessary characteristics like perceptibility, robustness against all types of attack and security. Lots of digital watermarking methods have been developed for still images and videos [6]. Most of them operate on uncompressed videos, while others embed watermarks directly into compressed video [7-12]. There are a number of issues that are in the video Watermarking but not present in image watermarking. Due to duplicity in video frames, video signals are highly susceptible to attacks such as frame averaging, frame dropping, frame swapping and statistical analysis. All developed watermarking algorithms have been broadly divided into two categories, namely spatial and frequency-domain. In spatial domain watermarking algorithm to directly alter the pixel values of the cover image while the transformed coefficients of the covert images have been altered to embed the watermarks in the frequency domain
