摘要
目前在各种形式的数字信息传输中加强信息的保密和安全问题日益引起人们的关注,考虑信息隐藏技术是为信息传递者将私有信息嵌入掩饰信息中来传递消息,因此对隐藏信息的检测在信息安全方面非常重要。为了检测二值图像的隐藏信息,提出一种基于统计特征的二值图像信息隐藏检测方法。该方法利用二值图像的统计特征,找出符合二值图像信息检测需要的统计特征进行隐藏分析,通过不同的隐写方法对统计特征的影响确定用不同的特征对具体的隐写方法进行隐藏信息的检测,从而保持对载体图像含有隐藏信息检测的准确性。试验结果表明:所提出的方法检测率在90%以上,可解决当前检测系统对于海量数据的安全性测试分析。
At present the problem to strengthen information confidentiality and security in various digital information transmission increasingly causes the attention of people. The information hiding technology transfers message by means of embedding private information in concealing information, so the hidden information detection is very important in the field of information security. In view of binary image information detection, presents a binary image information hiding detection method based on statistical characteristics. The method applies the statistical characteristics of binary image to find those in accordance with binary image information detection needed for hiding analysis, and through the influence of different steganalysis method on statistical characteristics, determines different characteristics applied for hidden informa- tion detection of specific steganography, thus maintain the detection accuracy of carrier image with hidden information. The experimental results show that the proposed method has the detection accuracy above 90% and can be used for the current test system in security testing analysis of huge amounts of data.
