The invention discloses a steganographic analysis system based on statistical detection and structure detection. The core detection module of the system integrates six statistical detection modules and two structure detection modules, which can use common image audio as a carrier, such as BMP Images, JPEG images, and WAVE audio, use mainstream steganography techniques, such as LSB steganography in the spatial domain, BPCS steganography, and structural steganography, to reliably detect hidden confidential documents. The present invention performs a joint judgment on the detection results of a plurality of detection modules through a joint acquisition and fusion mechanism, which has good applicability to the current mainstream steganographic methods, reduces the narrow application range of a single module, low average detection rate, High false alarm rate and other defects have realized high-quality and high-efficiency detection of various carrier types and various steganographic methods. At the same time, it has good scalability, which is convenient for integrating new detection modules and upgrading the detection performance of the system.
