适用于广播监视的安全视频水印方案

Secure video watermarking scheme for broadcast monitoring

考虑到广播监视应用中对视频片段的认证问题,基于三维离散小波变换,提出一种新颖的顽健视频散列算法,并利用生成的散列值和水印标识形成待嵌入的水印信息,以实现对视频片段的认证。在此基础上利用扩频水印技术提出一种适用于广播监视的安全、顽健的视频水印算法。理论分析和实验结果表明,提出的算法具有很好的安全性和顽健性。

Considered the authentication of video clips applied in broadcast monitoring, a new robust hashing algorithm for video was proposed based on the 3D wavelet transform （3D DWT）. The new proposed algorithm could realize the authentication of video clips by using the embedded watermark information created by the hash value and the watermark identifier. This new robust video watermark algorithm could also be applied in the security of broadcast monitoring. Based on the academic analysis and experimental results, the new proposed algorithm has good security and robust performance.
