提出一种基于统计特性的LSB密写分析方法,这种方法根据密写对原始数据统计特性的影响来判断秘密信息的有无.实验结果给出了不同阈值时的检测性能,当秘密信息量较大时,两类错误概率都可以得到有效控制.-This paper proposes a novel steganalysis technique based on the statistics method for LSB insertion, in which the change of statistical characteristic ca

介绍了一种基于统计特性的LSB密写分析方法,对其进行了改进并提出了可靠估计信息隐藏长度的方法。该方法利用相邻像素相关性定义了统计量,可根据阈值判断秘密信息的有无。对待检测图像进行二次嵌入,根据统计量的变化建立模型,能可靠估计秘密信息隐藏长度。实验表明,估计出的信息量比较准确。-This paper introduces a steganalysis algorithm based on statistics method for LSB steganograhpy and mends it,pr

函数功能:本函数将完成随机选择LSB的信息隐藏,载体选用BMP图，和提取隐秘与LSB上的秘密消息-Function: This function will be completed randomly selected LSB information hiding a secret message on the carrier selected BMP map, and extract hidden LSB

Steganography is the art of hiding information in ways that prevent the detection of hidden messages. Steganography, derived from Greek, literally means “covered writing.” It includes a vast array of secret communication methods that conceal the mes
