%X For analysis-by-synthesis(AbS) compressed speech a steganalysis method based on statistics of the pulse position parameters was proposed.Speech compressed by G.729 coding algorithm was taken as an example to analyse the characteristic differences of the pulse position parameters of cover and stego speech,and a new feature,the histogram flatness was defined.In the steganalysis method,four statistics including histogram flatness,the center of mass of histogram characteristic function,histogram variance,and th...
