摘要
目前数字水印的嵌入技术可以应用于包括文档、声音、图像以及视频在内的各种多媒体数据中,但是针对文本的数字水印嵌入技术研究相对较少。主要介绍当前常用的文本数字水印嵌入的基本模型和方法以及研究状况。首先介绍了文本数字水印的嵌入与检测模型。然后分析了当前文本数字水印的嵌入技术研究出现的问题。
Digital-watermark-inserting technology can be applied in various multimedia statistics including text, sounds, photos and videos at the moment. However the research aiming directly at the digital-watermark- inserting technology is comparatively rare. The paper mainly focuses on introducing the frequently used basic models of digital-watermark-inserting technology. In the beginning the inserting of text digital watermark and its testing model are introduced. Then the existing problems generated from the present digital-watermark- inserting technology have been analyzed.
