Abstract

为提高图像隐藏信息量，并同时降低图像失真率，本发明提出了一种双图像信息隐藏方法。图像的第一个像素用于判断两幅图像的顺序。剩下的每个像素可以嵌入K+1位，为平衡两幅图像的失真率并增加嵌入率，其中一位用于判断符号。信息接收者在收到两幅图像后，比较两含密图像第一个像素值大小即可定位图像顺序，再利用两含密图像对应像素值的和与差来复原原始图像像素，并提取出嵌入的秘密信息位。与最新图像信息隐藏算法比较，本发明具有隐藏容量大、失真率低且实现复杂度低的优点，在1.1bpp情况下的信噪比可达51.15dB。

一种双图像信息隐藏方法
技术领域
本发明涉及一种图像信息隐藏方法，属于数字水印，信息安全，保密通信与图像处理应用领域。
背景技术
随着互联网及信息媒体技术的发展，信息的安全性显得越来越重要。传统上采用加密技术保障信息的安全。但同时信息安全攻击者也知道了秘密信息的存在。近年来，在信息安全领域，学者们热衷于研究将某种特殊信息隐藏在图像中，并提出了各种各样的图像加密及信息隐藏方法，特别研究并提出了大量可逆信息隐藏方法。如常程程等人提出了一种基于双含密图像嵌高容量嵌入方法，桂新路等人则提出了一种基于总体预测扩展和自适应的可逆数据嵌入方法。然而现有的以图像为载体的信息隐藏存在2个问题：1、隐藏信息量不够，2、隐藏信息使图像载体失真较大。
发明内容
本发明所要解决的技术问题：1、隐藏信息量大且图像失真小， 2、信息提取后原始图像能无损恢复。为解决上述技术问题，本发明所采取的技术方案是提供一种双图像信息隐藏方法。该方法的信息隐藏实现步骤如下：
(1)按照从上到下从左到右顺序扫描图像，原始图像像素为I(i,j),第一及第二幅含密图像分别为按下式计算像素和,其中i,j分别为像素的行和列。则第一个像素为：
(2)除第一个像素外，其余每个像素I(i,j)的加密按照如下公式进行：
其中，为k位二进制秘密信息转换成的十进制值，为1位二进制秘密信息，函数为向下取整函数，函数为去求余函数。
该方法的秘密信息提取及原始图像的复原步骤如下：
(1) 根据两含密图像的第一个像素值，分别按下回确定含密图像的顺序及复原第一个像素值：
(2) 除第一个像素外，按照从上到下从左到右顺序扫描两含密图像，其余每个像素I(i,j)的复原及秘密信息的提取按照如下公式进行：
附图说明
图1 为本发明流程图。此处的附图被并入说明书中并构成本说明书的一部分，示出了符合本发明的实施过程并与说明书一起用于解释本发明的原理。
具体实施方案
下面结合附图对本发明的具体实施方式进行进一步的详细描述。
如图1 所示，本发明一种多位无损图像信息隐藏方法，其信息隐藏步骤如下：
(1) 读取一幅已知大小均为M*N的灰度图像，同时读取秘密信息文件，并将秘密信息转换为二进制码
(2)按照从上到下从左到右顺序扫描图像数据矩阵，读取第一个像素，按照如下方式确定两幅含密图像
(2)继续读取图像数据矩阵以及秘密信息数据，每个像素的加密按照如下公式进行：
接受者接收到两幅含密图像后，按照如下步骤复原图像及提前秘密信息：
(1) 读取两幅灰度图像的第一个数据，按照如下方式确定两幅图像的顺序
(2)按照如下方式复原第一个像素
(3) 除第一个像素外，其余每个像素I(i,j)的复原及秘密信息的提取按照如下公式进行：
