摘要
通过目前网络媒体流应用所面临的实际问题 ,提出了网络媒体流安全的基本概念和相应的安全防范措施 ,同时提出具体的数据安全算法以及相关的技术内容 .根据多媒体的具体应用 ,主要从流媒体压缩域加密技术 。
With rapid advances of multimedia applications on Internet, multimedia security problems on network have become more serious day by day. In the beginning of the paper, through the practical problems faced by multimedia security on network, we present the foundational principle and method accordingly. Then we enumerate the data security algorithms and relevant technologies. Base on the practical applications, we expound the concrete content in proper order by stream security in compression field, stream watermark technology and multicast technology.
