摘要

视频很容易被攻击者篡改、复制和重新分发，用于非法和金钱用途。这种行为严重损害了内容所有者的利益。尽管数字视频水印为保护版权做了大量的工作，但视频传输中典型的失真仍然可以很容易地消除嵌入的信号。其中，时间同步攻击是最常见的攻击之一。为了解决这个问题，我们提出了一种新的基于双树余弦小波变换(DTCWT)和奇异值分解(SVD)的抗帧率转换的视频水印算法。我们通过调整候选系数的形状来模拟水印嵌入，并进行包含适度时间冗余的组级水印，以抵御时间同步攻击。大量的实验结果表明，该算法对时间同步攻击具有更强的抵御能力，性能优于现有的盲视频水印算法。

A DTCWT-SVD Based Video Watermarking Resistant to Frame Rate Conversion

Videos can be easily tampered, copied and redistributed by attackers for illegal and monetary usage. Such behaviors severely jeopardize the interest of content owners. Despite huge efforts made in digital video watermarking for copyright protection, typical distortions in video transmission can still easily erase the embedded signal. Among them, temporal synchronization attacks is one of the most prevalent attacks. To address this issue, we present a new video watermarking based on joint Dual-Tree Cosine Wavelet Transform (DTCWT) and Singular Value Decomposition (SVD), which is resistant to frame rate conversion. We simulate the watermark embedding by adjusting the shape of candidate coefficient and perform group-level watermarking that includes moderate temporal redundancy to resist temporal synchronization attacks. Extensive experimental results show that the proposed scheme is more resilient to temporal synchronization attacks and performs better than the existing blind video watermarking schemes.
