Abstract |
Due to the extensive use of digital media applications, multimedia security and copyright protection has gained tremendous importance. Digital Watermarking is a technology used for the copyright protection of digital applications. In this paper, a comprehensive approach for watermarking digital video is introduced. We propose a hybrid digital video watermarking scheme based on Discrete Cosine Transform (DCT) The video frames are first decomposed using DCT and the binary watermark is embedded In this paper, we describe a visible watermarking scheme that is applied into the host video in the DCT domain. A mathematical model has been developed for that purpose. We have also proposed a modification of the algorithm to make the watermark more robust. |
