| 摘 要： | 为了在普通的通信环境中传递保密信息,提出了基于水印嵌入技术原理的信息隐藏算法。算法设计中以模运算为基础,将待隐藏的信息嵌入至原始图片的DCT系数中,采用率失真最优化的分析方法,控制信息隐藏过程中对原始图片的变形影响,尽可能地在一个图片中嵌入更多的隐藏信息。经过测试分析表明:在视觉允许的失真条件下,每个DCT数据块可以嵌入1个字节的数据量。 |

| Abstract: | In order to transmit privacy information in the ordinary network environment,the information hiding algorithm based on watermark embedding technology was proposed.This algorithm was designed with the mold operation as the foundation.It could embed the hideaway information to the primitive picture DCT coefficient,with the use of distorted optimization analysis method to control the distortion influence to the primitive picture so that much information could be embedded in a picture.Tests indicate that under ... |
