摘要
网络电话具有资费低、易操作、平台兼容性高等优点,因此得到迅速发展并获得广大消费者的青睐。Sipdroid是一款开源且使用简便的网络电话软件,其采用的Sip协议具有结构简单、支持多媒体业务的开展、符合互联网网络结构、可扩展性好、应用灵活等优点。基于的Android平台具有良好的开源性和兼容性。网络在为人们提供信息共享的同时,对信息的安全性也造成了一定的威胁。本文为了进一步提高传输信息的安全性,在Sipdroid系统的基础上进行分析设计,添加信息隐藏模块,在实时语音通话的同时,实现了隐藏信息的嵌入、传输与提取。测试结果表明,在加入信息隐藏功能之后Sipdroid仍具有良好的使用性。
VoIP has the advantages of low cost, easy operation, high platform compatibility and other advantages, getting the rapid development and the favor of the vast number of consumers. Sipdroid is an open source Internet phone software and it is easy to use. Its use of the Sip protocol has the advantages of simple structure, to support multimedia business, with the Internet network structure, good expansibility, flexible application and so on. Sipdroid is based on the Android platform, and it has good open source and compatibility. When the network provides people with information sharing, it also causes a threat to the security of information. In this article, in order to further improve the security of transmission information, we analyze and design, based on Sipdroid system and add information hiding module, real-time voice calls at the same time, to achieve the hidden information embedded, transmission and extraction. The test results show that Sipdroid still has good usability after adding information hiding function.
