Secret information detecting system based on expert system method

Abstract

The present invention discloses a secret information detecting system based on an expert system method. The system comprises an image collecting engine, a detector, a report generating module, an image database, a knowledge base and a knowledge acquiring module, wherein the image collecting engine is used for quickly collecting the digital images with different formats from the network and providing the data to a detector. The detector determines whether information is concealed in the image which is collected by the image collecting engine or is in the image database according to the knowledge in the knowledge base, and then generates a determining report in a determining report module. The information detecting method provided by the invention can fully use the information of inserted information characteristic, image characteristic, concealing tool, algorithm characteristic, etc. Not only the detectable range is enlarged, but also the detection precision is increased. The knowledge acquiring method based on a rough set is introduced into the field of concealed information detection thereby extracting valuable information from large numbers of experimental samples. The secret information detecting system of the invention has extendibility.

Description

technical field [0001] The invention belongs to the technical field of information security, and relates to an information hiding detection technology and an expert system method, in particular to a detection system for secret information based on an expert system method. Background technique [0002] As a form of covert communication, information hiding technology has been increasingly used in the military field. However, when information hiding technology is used as a tool for criminals and terrorists to spread information and organize terrorist attacks, it will bring disastrous consequences. Therefore, the detection technology of information hiding has become a research hotspot in related fields at home and abroad. Scholars at home and abroad have made some achievements in the field of information hiding detection at this stage, and have some detection algorithms. For example, Andress Westfeld and Andreas Pfitzmann, the visual attack and statistical attack method propose...
