摘　　要：涉密单位的物理隔离网络很大程度上保证了涉密信息的安全.但涉密网络不可避免的信息输出需求使得不法分子可通过信息隐藏等技术非授权输出涉密信息.针对信息隐藏技术可利用多媒体文件自身信息的冗余性和人体感知对文件细节的不敏感性给网络和信息安全带来的隐患,基于文本和图像信息隐藏检测技术,结合涉密单位的保密管理要求,提出一种针对信息隐藏的检测方法.该方法可有效提升涉密单位对信息输出环节的管控能力.The physical isolation network of classified units ensures the security of classified information to a great extent.However,the inevitable output need of information in secret network makes it possible for criminals to output classified information unauthorized through the use of information hiding technology.Considering the hidden dangers for network and information security caused by the redundancy feature that the information hiding technology could utilize the self information of multimedia files,and the insensitivity of human perception of the file details,we propose a detection method for information hiding basing on the text and image information hiding detection technology and combining the secret management requirements of classified units.This method can effectively improve the control ability of the information output process for the classified unit.
