一种基于LSB隐写算法的图像盲检测方法

Blind Detection Technology Based on Image LSB Steganography Algorithm

在隐写技术被动检测模式下,用数学方程对LSB图像隐写算法进行抽象和建模,定量分析被检测图像的隐写信息边界情况,根据隐藏信息的比特数推出隐藏信息的检测概率和误检概率的表达式,提出一种基于LSB隐写的图像盲检测方法。基于LSB隐写的盲检测方法在LSB隐写算法嵌入图像的隐藏信息超过一定范围时,可以有效分辨出原始图像和隐藏信息。

In the steganography and passive tracking-mode,mathematical equations are used to abstract and model LSB steganography algorithm.Quantitative analysis of hidden information on images,which is hidden by detection,are used to make sure the biggest capacity of steganography algorithm.Then the blind detection is proposed based on the steganography image.Based on LSB steganography image and the blind detection method in LSB algorithm,which embeds on image with the steganography algorithm and is over a certain range of information,the original image and hidden information can be effectively distiguished.
