Data Hiding in Text Document Images by Cloud Model

摘要：

In this paper, we proposed the new design for data hiding in test document images by cloud model. The design of watermark embedded formula primly balances the contradiction between transparence and robustness. The suitable location of pixel is determined by cloud model generator and corresponds to reference point at center of in-circle of triangle. Hence, the watermark can be extracted without referring to the original image. The suitable locations of pixel are limit inside in-circle of triangle, which are three vertexes of Harrier corner points. Experimental results using text document image include Chinese and English are provided to indicate its practical applicability.
