Following the expansion of communication, hiding of confidential information has become a crucial requirement. Watermarking is one of the techniques used to hide information in image, sound and especially text. Comparing to English and Chinese texts, there has been little work on Persian texts, because of special characteristics of Persian texts. In this paper, a method is proposed, for the first time, to hide information in the curvatures existing in some Persian letters. One of the main steps in watermarking process is detection and separation of letters using the appearance features of the letters, and the way they stand within the text. Since that in the proposed method, information are embedded in Pixels of curved letters, the results of proposed method show the good quality, the capacity and the robustness of this method.
