【摘要】 信息隐藏检测技术是近年来一个新兴的研究领域,用统计实证方法对最低有效位替换数字图像的数据特性进行研究分析,利用S-Tools对相同载体嵌入不同格式图像、不同载体嵌入相同格式图像的实例的分析,说明利用差分直方图可以检测图像最低有效位的信息隐藏,并通过仿真说明方法的有效性。更多还原

【Abstract】 Information hiding detection technology is a new and developing study area in recent years,statistical method and demon-stration is used to study data speciality of digital image replaced in the least significant bit,S-Tools is used to analyze examples of the same carriers embedded in different format images and different carriers embedded in the same format images,the process makes out the difference histogram is used to detect information hiding in the least significant bit of image.Lastly,the validity of forgoing method is shown via simulation.更多还原
