基于短视频分类和时长的信息隐藏方法

Method of Information Hiding Based on Short Videos’ Classification and Lengths

为了充分利用短视频资源,提出了基于短视频分类和时长的无载体信息隐藏方法。该方法对短视频内容进行分类,设置特定类别作为取位标志;对短视频时长划分区间,分别用来映射秘密消息、代表传输开始和结束标志、代表用户的正常生活。分析结果表明,该方法具有5bits/视频的高隐写容量、较高的隐蔽性和鲁棒性。

In order to make full use of these resources,a carrier-free information hiding method based on short video classification and lengths was proposed.Short videos′content is classified and some specific categories is set as the flag of taking bits;Short videos′lengths are divided into intervals,which are used to map secret messages,represent the start and end of transmission marks,and represent the normal life of users.The analysis results show that this method has high capacity(5 bits/video),high concealment and robustness.
