Transductive　support　vector　machine　(TSVM)　is　a　technology　which　starts　with　labeled　samples　and　aims　at　recognizing　and　classifying　the　given　unlabeled　samples.　In　this　paper,　the　feasibility　of　applying　TSVM　to　universal　image　steganalysis　was　analyzed,　and　a　universal　steganalysis　method　for　Gif　image　based　on　TSVM　were　proposed　and　implemented.　The　experimental　results　shown　that,　in　the　condition　of　few　labeled　samples　and　massive　unlabeled　samples,　this　method　can　achieves　the　approximate　detecting　effect　of　old　method　based　on　traditional　inductive　support　vector　machines.　Thus,　the　model　of　universal　steganalysis　for　Gif　image　based　on　TSVM　is　more　practical.
