Abstract

Camcorder-based piracy is increasing nowadays because of the high quality of camcorder devices. The most affected industries are theatre and cinema. To defeat theatre piracy which causes huge loss to the motion picture industry of the world, here in this paper, a robust discrete wavelet transform (DWT) based video watermarking approach has been presented in which a payload formed with date-time of the show, registration number of theatres, and six-digit ZIP Code of the theatre location embedded in the movie before it plays back in the theatre. To assure that the video and the algorithm are of good quality and robustness, the adaptive watermarking pattern has been used to minimize the watermarking area in the host video. In this study, YCbCr color space has been adopted to use Y factor of the image to watermark because the luminance part of the image is the least sensitive to the human visual system. This approach shows the convincing robustness against the geometrical attack and camcording attack, which is the most affecting factor in camcorder piracy. As the proposed approach is good enough to disclose the place and time of piracy, it may deter the pirate to do piracy.
