Abstract: Motion vector modulated steganographic approach is an important type of information hiding method in H.264/AVC video streams, due to its large embedding capacity and low additional distortion induced in reconstructed video frames. In this paper, a novel video steganalysis algorithm is proposed for this type of information hiding method. Firstly, this paper designs a correlation network model to illustrate the correlation between temporal and spatial adjacent motion vectors. Secondly, we obtain a strong correlation network model by simplifying the original correlation network model through a pruning process, accordingly, the quantitative feature vectors of the strong model can be represented through quantifying the correlation of vertexes for steganalysis purpose. Finally, a steganographic detector based on the extracted feature vectors is built by using the support vector machine (SVM). Experiment results show that the proposed algorithm achieves a satisfying performance with the detection accuracy of more than 90%.
