Review of Image Steganalysis Based on Deep Learning

Steganography and steganalysis are one of the research hotspots in the field of information security. The abuse of steganography has caused many potential safety hazard. For example, illegal elements use steganography for covert communications to carry out terrorist attacks. The design of traditional steganalysis methods requires a large amount of prior knowledge, and the steganalysis methods based on deep learning use the powerful representation learning ability of the network to autonomously extract abnormal image features, which greatly reduces human participation and achieves good results. To promote the research of steganalysis technology based on deep learning, this paper analyzes and summarizes the main methods and work in the field of steganalysis. Firstly, this paper analyzes and compares the differences between traditional steganalysis and deep learning-based steganalysis. Furthermore, according to the different training methods, the steganalysis models based on deep learning are divided into two categories:Semi-learning steganalysis model and Full-learning steganalysis model. The network structure and detection effect of various types of steganalysis based on deep learning are introduced in detail. In addition, we analyzed and summarized the challenges that the adversarial samples pose to deep learning security, expounds the detection method of adversarial samples based on steganalysis. Finally, this paper summarizes the pros and cons of existing steganalysis models based on deep learning and discusses its development trends.
