摘要
将一种基于双随机相位编码的图像隐藏算法应用于文本。该算法将待隐藏的文本信息按照一定方式转化为类似于图像的二维矩阵,采用双随机相位编码算法对其进行编码,然后嵌入到以一定方式扩展的宿主图像中。将处理后的文本信息隐藏到宿主图像中,提高了传输的安全性。通过理论分析及仿真实验证明了方法的有效性,并分析了将文本信息转化为图像的不同方式对于算法性能的影响。
The image-hiding method based on double random phase encoding technique was applied to text.The proposed method transformed the hidden text into an image,used double random phase encoding technique to encode the image and embeded it to the host image,which was extended with a certain method.Hiding the transformed text in the host image would enhance the transmission security.The effectiveness of the proposed method was demonstrated with theoretical analysis and simulation experiments,while the performance of transforming the text into image with different methods was analyzed.
