摘要 描述了一种基于MPEG-Ⅱ彩色视频中的无损信息隐藏方法,该方法在Alattar算法的基础上,使宿主矢量类型的判别由四个不等式,减少到两个不等式,降低了算法的时间复杂度.数据嵌入过程中采用简单数据链路SDL成帧.在局域网上进行了隐秘传输模拟实验,从嵌入信息的视频中正确提取出所嵌入汉字或二值指纹图像后,原宿主视频可无损恢复.该方法较适用于视频中的隐秘传输及产权保护等领域. A lossless information hiding method based on MPEG-2 color video is proposed in this paper. The method is based on Alattar＇s algorithm and it reduced type discriminant conditions from Alattar＇s 4 inequations to 2 inequations, so it reduced time complexity. A simple data link frame is used during data hiding processing and covert communication experiments are simulated in local networks by using the algorithm. Host video information can be restored losslessly after embedded Chinese characters or fingerprinting images are correctly extracted from the video which embedded information. The method can be applied to covert communication or copyright protection of video product.
