Statistic supervision and structure supervision based hidden messages analysis system

Abstract

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.

Description

technical field [0001] The invention relates to the field of information hiding detection. Specifically, the invention proposes a steganalysis system based on statistical detection and structure detection. Common steganography techniques mainly include spatial domain LSB steganography, frequency domain steganography, BPCS steganography and structural steganography. The invention is aimed at the detection of space domain LSB steganography, BPCS steganography and structural steganography. Background technique [0002] Since 2002, the development of popular steganography software represented by camera shy (half-covered face) has sprung up, constantly updated and expanded, and other similar products designed based on information hiding technology have also appeared rapidly. Steganography and cryptography are equally important in the field of information security. Steganography is like a double-edged sword. If we do not conduct in-depth research on both positive and negative asp...

Problems solved by technology

[0008] 1) Steganography is only used by a few important sensitive users

[0009] 2) The multimedia formats on the Internet are diversified, and most of the detection algorithms studied at home and abroad are mainly general statistical attacks. Although these algorithms have strong applicability, the detection accuracy is not practical

[0010] 3) The research on the detection of steganographic tools currently mainly stays in the analysis of open source steganographic software or software released by some teaching institutions and individual enthusiasts. However, there are almost no users who actually use these software to transmit secret information. For many popular steganographic software Due to the difficulty of analysis, few people can come up with accurate detection methods, but they may be secret communication tools frequently used by users
