LSB-Data-Hiding-Image
- 图像的组成无非是一些字符串或者一些字节组成的字符串,然而,每一个字节数据位的重要度并不是一样的,两个相邻字节往往只有低位是不一样的。例如:00100110和00100111代表了两个不同渐变度的红色,但是就人眼是分辨不出来的。最低有效位LSB算法,就是利用这一点,达到图像压缩,或者数字水印的功能。-The composition of the image is nothing more than some number of bytes or string composed of string,

- 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
