摘要
文章提出了一个基于盲对称检测的视频水印时间同步模型,在嵌入模型中使用有限状态机来生成嵌入密钥,在检测模型中用队列存放预测的多个连续帧所使用的密钥,从而实现视频水印检测的时间同步。实验结果表明,此方法可以有效地对抗帧丢失等时间同步攻击。
In this paper, a temporal synchronization model for blind symmetrical video watermark detection is presented. In the embedding models, we use the finite state machine to construct the embedding watermark key. In the watermark detector, we use a queue to perform a search to establish and maintain temporal synchronization. Experimental results support that the method can protect video from frame dropping attack.
