| 摘 要： | 水印技术已成为国际上的研究热点,视频水印大量应用于版权保护、隐含标识、信息认证和隐蔽通信等。文中主要研究一种安全的数字视频水印系统,该系统基于一种视频帧的水印算法,使用二值图像作为水印信息,采用每帧索引的方法,能够很好地抵抗针对视频水印的攻击。此外,该系统使用NTRU加密,既能利用公钥来检测视频是否是正版产品,又能在遭受公钥攻击后,使用私钥进行版权认证。

| Abstract: | Nowadays, the digital watermarking technology becomes a research hotspot, and video watermarking is widely applied in copyright protection, implicit identification, message authentication and covert communications. A secure digital video watermarking system is proposed, which, based on NTRU encryption and video frame watermarking algorithm, with binary image as watermarking information, and by using the frame index approach, could perfectly resist the attack against video watermarking. In addition, the system, by using NTRU encryption, could detect whether the video is a genuine？product, while authenticate the copyright with private key when suffering public-key attack. |
