AB - This paper proposes LSB steganalysis method based on variance extension by the bit seperation. LSB embedding is the simplest and easiest among many stegonography schemes. But it is difficult to detect secret message due to modified embedding methods. To improve the detection rate to existence of hidden message, we expand the noise variance of image by separating pixels into upper and lower 4bits. Then we decompose each seperated sub-images by using 3-level wavelet transform, extract 84D statistical moments from characteristic function of original and subbands. Multi-layer perceptron(MLP)classifier is used to discriminate between cover and stego image. We experiment our proposed scheme on modified LSB embedding method. The proposed method improves the detection rate to existence of hidden message.
