摘　　要：近年来,国内外对数字水印的方法研究有了很多进展,但是针对二值图像文本水印技术的研究还相当有限,由于二值图像自身的特殊性,与一般的图像水印有很大不同,用于灰度图像和彩色图像的数字水印隐藏方法一般很难应用于二值图像。文章介绍了国内外对二值图像文档水印技术的研究动态,重点介绍了一种比较主流的二值文本图像水印方案,并通过对汉字特点的分析,基于该方案提出一种新的应用于汉字文本图像的简便的盲水印方法。In recent years,either inside or outside nation,there arc a great progress in watermarking method research, but the technique research aiming at Binary Images is limited.Because of the speciality of Binary Images itself,the Binary Images watermarking have big difference to the common watermarking,the data hiding methods which is used in gray image and color image is hard to be used in Binary Images.In this paper,we will introduce some research trends of watermarking technique that aiming at Binary Images document and introduce a mainstream Binary Images watermarking solution importantly,by analyzing the characteristic of Chinese character,a new and handy blind watermarking solution which is used in Chinese character image is proposed.
