The shifted halftone dots are applied for hiding the information in the stamps. The experimental results show that the proposed method could improve the elimination of artifact, and the personalized stamp looks more beautiful and possesses unique diversity of hidden contents. It will be able to use this steganography method to embed the required hidden information in an automatic manner. In addition to the value of stamps collection, it also contains innovative design with cultural significance.個性化浮水印網點位移資訊隱藏個人化郵票Specific WatermarksDot ShiftingData HidingPersonalized Stamps
