Abstract:

In order to improve the detection accuracy of small embedding rate steganography, an image steganalysis method based on the highly modularized convolutional neural network is proposed. First, the fundamental network is built by repeating residual network units to extract the complex statistical properties of digital images. Then, extracting the channel information on the residual image by adding the group convolution, it is very good to strengthen the signal characteristics from the hidden information. Finally, a large number of datasets are used to train the network, and the image steganalysis method based on the modularized residual network is obtained. Experimental results show that compared with the existing methods, the proposed method has a better performance, and extracts more effective image features. Meanwhile, using the residual network module as the template, the network model can be easily built to facilitate adjustment and training.

Key words: steganalysis, residual network, group convolution, modularized, low embedding rate
