| 摘 要： | 首先分析了原有流媒体隐蔽通信系统模型在传输机制上存在的问题.在此基础上改进了原有的传输方案,提出了一种新的基于流媒体的隐蔽通信的可靠传输机制,并进行实现和实际测试.实验结果表明,对于只有当载体满足一定条件时才可以嵌入的隐藏算法,新的传输机制也能保证可靠传输,性能较以前的方法也有长足的改善.

| Abstract: | The authors of this paper first analyze the drawbacks of the transmission mechanism used in the previous streaming media based information hiding communication system.According to the analysis,a new reliable transmission mechanism is proposed,which outperforms the original scheme in term of effective usage of the channel bandwidth.The new mechanism is implemented and tested.Extensive experimental results show that the new mechanism can deal with embedding algorithm which has a very limited capacity,and the algorithms which has certain requirement for the cover media in embedding. |
