摘要 本文提出了一种基于数字水印的多媒体课件版权保护方法。此方法将一幅图片以不可见水印的方式嵌入到视频流中,通过检测数字水印的存在性来确定课件的版权。经实验证明,此方法对多媒体课件的版权保护比较有效。 This paper proposes solution for the protection video courseware based on digital watermark.This method embeds an image into video stream as invisible watermark,and identifies the copyright of the Courseware by detecting the existence of digital watermark.The experiment proves the effectiveness and good results of this method.
