| 摘 要： | 信息隐藏的原理就是利用多媒体中存在很大的冗余信息来隐藏秘密信息。该文在传统的LSB算法基础上,结合人类视觉系统的掩蔽特性,对载体图像分成平滑区、边缘区和纹理区,相应地嵌入秘密信息;实验结果表明,用该算法进行信息隐藏具有较好的隐蔽性,且具有较大的隐藏容量。

| Abstract: | The principle of information hiding is to embed secret messages in the large amount of redundant information of multimedia.On the basis of the traditional Least Significant Bit(LSB)algorithm and in light of the masking characteristics of the human vision system,the image is demarcated into the smooth area,edge area and texture area,and secret messages are embedded in the corresponding areas respectively.Experiment results show that with the method,good invisibility can be achieved,and the hiding capacity of information is large. |
