In these days, the open computer networks make possible to use intellectual properties without any degradation of the multimedia data such as document, audio, image, and video. In this paper, we suggest a digital watermarking scheme that produces each different marked document by embedding a unique mark of original user using diagonal profile. This can be applied a technique to prevent unauthorized user from discouraging illicit copying or redistribution of document images by retrieving embedded mark of original user. This technique can easily detect attempt to remove or change the watermark by the feature of diagonal profile and it does not affect the skew since the watermark embeds to be neighbored with a black pixel value. And we produce noisy image by increasing the copy generation, we find out that it occurs unambiguous in watermark extraction procedure. We, therefore, propose a tip to extract the watermark after removing produced noise by copying.
