Detection of motion vector based video steganography

In this paper, a new steganalysis technique is proposed to detect the motion vector based steganography for the compressed videos. The proposed scheme explores the flickering effect, the changes in the prediction error and statistical anomalies in the motion vectors due to embedding to detect the presence of steganographic messages. The experimental results show that the proposed method effectively detects the data embedded in motion vector based steganographic techniques more accurately than the already existing schemes.
