Abstract

Aiming at the problem that the adaptive steganalysis of images is difficult, and the existing models are difficult to make a targeted analysis of favorable areas of images, this paper proposed an image steganalysis model SA-SRNet based on self-attention. The model introduced self-attention into SRNet to guide the model to focus on favorable areas for steganalysis in the global image and the long-range dependencies of image. It solved the problem that the training of hard-attention was easy to fall into local optimum. First, the reward mechanism used reinforcement learning to guide the model to find the detection point which was most favorable for steganalysis. Secondly, the self-attention used the detection point to generate the important attention image. Finally, the replace mechanism used the important attention images to replace the mis-classified images to improve the quality of training set and the discriminant ability of the model. This paper carried out the experiments on BOSSbase 1.01 dataset. The results show that SA-SRNet can achieve better accuracy of steganalysis than that of SRNet, and can improve the accuracy by up to 1.8%.
