本論文利用個人化郵票做為載體,選出其中的青色版做為實驗用區域,將個性化浮水印圖像隱藏在內,以達到個人資訊隱藏於個人化郵票之目的,過程中設計合成技術以利網點加密形成個性化浮水印。方法為以數位半色調技術製作網點背景,在背景範圍內所選取的網點是同步性位移,選取邊框與背景網點位移後即產生加密浮水印。再利用本研究的程式批次產生隱藏的浮水印圖像資訊,可提高製作多樣化隱藏內容的獨特性,並減少網點位移後由肉眼觀看的不連續瑕疵,讓圖像看來愈加平順美觀。研究以「國立臺灣師範大學榮獲邁向頂尖大學計畫」作為郵票設計主題,將個人姓名隱藏於郵票附箋,藉以向臺灣師大默默辛苦付出的教職員生致敬,提高郵票本身的收藏價值,亦具有個性化輸出及文化創意之加值應用。
