基于分存的多幅图像信息隐藏方案*

在秘密图像分存的基础上，提出一种多幅图像进行信息隐藏的算法。首先把秘密图像分存到指定的两个毫无关系的图像中，然后在公开图像的奇数行（列）嵌入第一幅图像，在偶数行（列）嵌入第二幅图像，从而实现多幅图像在一幅公开图像中的隐藏。给出了两幅图像嵌入一幅图像的实验，并对隐藏性能作了分析与比较。该算法原理简单有效，编程容易，信息的嵌入与提取速度快，并且这种多幅图像进行信息隐藏的方法可以嵌套于目前的大多数算法，有很强的推广性。

Multiple images hiding scheme based on image share

This paper proposed an algorithm of multiple digital images hiding based on image share.Shared the secret image in two independent images firstly, and then embedded the information hiding scheme that the first secret image in the odd lines of public image, and the second one in the even lines. Finally,hid multiple images in one public image.Taken the experiments which hide two images into one public image.Analyzed and discussed the characteristics of the scheme.The principle of the algorithm is simple, and it is also easy to program. Hiding and extracting information are fast.The scheme can be used in many present algorithms of hiding information. The validity of the scheme is proved, and the scheme can be popularized largely.
