| Abstract: |
We present a method for detecting steganography using +-1 embedding. The method uses a lossless compression technique to compress the last two bitplanes in an effort to model the image structure where the data may be hidden. A small number of statistics are then computed using the model and fed into a support vector machine to classify detection results. Results presented are obtained using k-fold cross-validation method using a large set of never compressed grayscale images. Detection results show improvement over current +-1 steganalysis methods. |
