JPEG image steganalysis system based on symmetry filter classification

The invention discloses a JPEG image steganalysis system based on symmetry filter classification. The system comprises an inspection unit, a data extraction marking unit, a storage unit and a verification unit, and is characterized in that the inspection unit comprises a USB input port, a data input port and a network input port; and the output end of the information integration module is connected with the input end of the feature recognition module and the input end of the color cell recognition module. The invention relates to the technical field of image recognition. According to the JPEG image steganalysis system based on symmetric filter classification, through the application of the system, the filters are more convenient to classify and rank, the filters with different properties can be marked, and then the feature information of the filters is acquired to be recorded and marked until steganalysis is completed; and in the whole analysis process, excessive manual control is avoided, so that the energy
