对JPEG图像随机LSB隐写系统的提取实际上是对隐写密钥的恢复。
The point of the extracting attack to random LSB steganography of JPEG images is to recover the stego-key.
分析了隐写系统和隐写分析的基本原理，提出了一种新的隐写载体—纠错编码。
In this paper, basic principle of steganographic systems was analyzed, then a new steganographic cover -error -correction code was presented.
介绍隐写分析的原理，给出隐写分析方法的四个评价指标，从隐写分析类型的角度给出图像隐写分析通用原型系统。
Steganalysis principle, gives four estimated values for steganalysis method and general prototype system of image steganalysis based on types of steganalysis from the view of warden are introduced.
由于视觉系统具有一些视觉掩蔽效应，因此基于视觉特性的图像隐写算法可以在保证较大的数据嵌入量的同时，使得隐写图像保持良好的视觉效果。
Human visual system has some masking effects, that is the reason why steganography based on the characteristic of HVS has good visual imperceptibility and large payload.
