【摘要】 给出了一个W(L)矩阵,及相关的性质,并在此基础上,提出了一种新的数据嵌入方法,可在(2L+1)bit宿主信息中,嵌入2Lbit数据而最多只需要修改Lbit宿主信息。这种方法,有较大的数据嵌入率,且对宿主信息的改变也较少,比较适用于大信息量,特别是流媒体数据的隐藏及隐秘传输。更多还原

【Abstract】 This paper presents a novel method of data embedding based on a W(L) matrix and its properties.With the proposed method,we can hide 2L bits of data in the(2L+1) bits of host information,only need to modify no more than L bits host data.Because of its high embedding efficiency and small changes in the host information,the method is suitable for large amount of information,especially for data hiding or secret transmission of streaming media data.更多还原
