Abstract :
In this work a novel scheme of embedding data in a video sequence is presented. The method is based on a modified Quantization Index Modulation (QIM) embedding algorithm in the 3D-DCT domain. Different zones in the 3D DCT cube have been analyzed in order to obtain better performances in term of robustness and imperceptibility. Analysis of the results shows the effectiveness of the proposed scheme.
