In this paper, we focus on detecting data hiding in motion vectors of compressed video and propose a new steganalytic algorithm based on the mutual constraints of motion vectors. The constraints of motion vectors from multiple frames are analyzed and formulized by three functions, then statistical features are extracted based on these functions. Moreover, we also incorporate calibration method to...
In this paper, we propose a universal spatial feature set for video steganalysis. This feature set comprehensively exploits the correlation of adjacent pixels and can be viewed as a generalized extension of most correlation based features. We also develop a new approach to extract inter-frame features for video steganalysis. Our method can be universally applied to detect different video steganographic...
The security of multimedia information in general and the security of visual information in particular have increasingly become an issue of great concern in our networked society. Biometrics, cryptography and data hiding provide effective and often complementary solutions to information security from different perspectives. In this paper, we present a brief overview on the state-of-the-art of research...
