摘要
针对目前流媒体信息隐藏尚无具有普遍意义的理论模型问题,从流媒体的载体特性出发,借鉴信息论和最优化技术,在阐述流媒体信息隐藏的安全性原理的基础上,给出了其不可感知性和不可检测性的定义.分析了隐藏容量的相对性和安全容量问题,进而提出一种流媒体多隐藏信道安全容量模型,指出多隐秘信道的并行使用将有助于获得最佳的隐藏性能.
Aiming at the problem that the streaming-media information hiding has no universal theory model until now, the formal definition of perceptive transparency and statistical security were given based on elaborating secure principle of streaming-media information hiding using information theory and optimization techniques from the carrier of streaming-media characteristic. The relativity of hiding capacity and secure capacity were investigated, a secure capacity model of multi-hiding information channel based on streaming- media was proposed, the coven multi-channel of streaming-media can be employed in parallel to achieve a nice hiding performance.
