一种用于视频流的强鲁棒性数字水印方案

研究了视频流的水印嵌入和提取,为视频流提供版权保护。针对现阶段越来越多的视频流盗版现状,为了保护版权方的利益,提出了一种将版权方信息作为数字水印嵌入到视频流中的方法。通过该方法,在视频流中嵌入了不易破坏的版权方的信息,该信息可作为流媒体的追溯标记和证据。经实验证明:改进方案与其他数字水印方案相比,具有很强的鲁棒性,可抵抗视频的重复编码,抵抗分辨率缩放,抵抗一定程度的内容修改,支持水印的盲提取。

Robust Digital Watermarking Scheme for Video Stream

To provide copyright protection for video stream,the watermark embedding and extraction were studied.For more and more of stream piracies,in order to protect the interests of copyright side,the paper presented a digital watermark embedding method which puts copyright information into video stream.Using this method,the information embedded in the video stream is not easy to be damaged.And the information can be the retrospectively label and evidence for the streaming media.The experiment shows that: compared with other digital watermarking schemes,it has a strong robustness to resist the repeated video encoding,resolution scaling and a certain degree of content changes.It also supports watermark extraction.
