本文提出了一种基于双随机相位编码技术的信息隐藏方法。在此方法中，数据被分为实部和虚部。编码数据的实部与虚部通过灰度叠加的方式嵌入到一个足够大的宿主图像中。合成图像相较于原始宿主图像不会有严重的降质。在解密过程中，无需原始宿主图像即可直接对合成图像进行解密。讨论了影响合成图像以及重构图像质量的因素。展示了如何通过调整确定的宿主图像和隐藏图像的叠加权重来实现最佳效果。
This paper proposes a method for information hiding based on doubled-random phase encoding technology. In this method, data is split into real and imaginary compartments. The real part of the encoded data is embedded into a large enough host image, together with the imaginary part through grey level superposition. The composed image is not subject to severe degradation compared to the original host image. During the decryption process, the composed image is decrypted directly without the use of the original host image. Factors affecting the quality of the composed image as well as the reconstructed image are discussed. It is shown how optimum results are achieved by adjusting the superposition weight of the definitive host and hiding images.
