Steganalysis of MSU Stego Video based on discontinuous coefficient
Jialin Wu, Ru Zhang, Ming Chen, Xinxin Niu · 2010
MSU(Moscow State University) Stego Video is a public video steganographic tool. It uses a specific data distribution mode to load secret data, so that the message can be extracted correctly even the stego video are compressed. In this paper, based on the analysis of the distribution characteristics of the embedded data, a detection algorithm against MSU embedding is proposed by utilizing the difference of block artifacts distribution between natural frames and stego frames. The algorithm can reliably detect the existence of hidden data. It is easy to implement and computationally efficient, and is suitable for real-time detection.
