This paper proposes a new frame-by-frame averaging based steganalysis method. The test frame is passed through two low-pass filters simultaneously and the difference of the filter outputs is tested for Gaussianity. Experimental results on antipodal watermarked videos show performance comparable to that of the Wiener filter based steganalysis.
In this paper we present a frame by frame steganalysis scheme for digital video sequences based on average filtering of frame. The goal of steganalysis is to detect and/or estimate potentially hidden information from observed data with little or no knowledge about steganography algorithm and/or its parameters. Our blind scheme is successful in detecting hidden information of antipodal nature.
