Abstract

Video watermarking has been proposed to provide content protection, authentication, and indexing. The primordial compromise of watermarking was between robustness, invisibility and capacity. Unless, digital progression imposes new criteria as the processing time which became an important criterion for assessing and selecting the optimal technique. To satisfy these requirements a new approach based on Krawtchouk moments and DCT (Discrete Cosine Transform) is proposed. In fact, a defined part is firstly selected from the original frame in order to guarantee a real time treatment even with high definition video (HD). Secondly, Krawtchouk moment’s matrix is extracted from the luminance component and then transformed using the 2-D DCT and a set of coefficients is selected to be marked. Finally, the marked frames are generated based on marked moments. Experimental results show that the proposed technique is robust against several attacks besides providing a high level of invisibility and a real time processing.
