摘要

时间同步攻击是水印盲检测的一大挑战

如果嵌入水印的视频帧同步性被破坏

就会导致水印提取失败

为了有效的抵抗时间同步攻击

提出了一种基于运动矢量统计特性的Mpeg4视频水印算法.该算法通过分析Mpeg4标准的压缩方法和运动矢量的数据统计特性

利用运动矢量幅值分布特点选取欲嵌入水印的运动矢量进行水印嵌入

克服了传统水印检测器对水印同步的依赖.经实验证实

该水印系统对常见的时间同步攻击具有较好的鲁棒性及透明性等特点.

Abstract

Temporal synchronization is one of the challenges for blind watermark detection.If the detector’s input is watermarked but synchronization fails

the embedded watermark will not be detected.For attacking temporal synchronization efficiently

a novel Mpeg4 video watermarking algorithm is proposed based on data statistical classification of motion vector and Mpeg4 compressed format.According to motion vectors’statistical characteristics

we choose motion vectors to embed watermark.The algorithm avoids the sensit...
