本研究主要目的是透過正交線網浮水印加密設計，應用於個人化郵票設計中。藉由正交線網加密技術，針對圖像的亮部及暗部進行調整與修正，並透過數位半色調技術，將連續調影像分別轉換為水平及垂直線網影像，另將隱藏的資訊透過邏輯運算合成新的影像，讓隱藏資訊的網線瑕疵更少且不影響人眼辨識，達到個人化郵票設計加密效果。使用者並可使用光學輔助儀器(光柵板)於模擬輸出之浮水印上進行解密以呈現隱藏訊息。本研究的個人化郵票設計能夠達到資訊隱藏的功能，並兼具美觀性及創新性，提昇個人化郵票等有價證券之附加價值。

The main purpose of this research is to design the multiple angle encryption in halftone line structure. In this research, using digital halftoning technique by multiple angle encryption is carried out through the horizontal and vertical screen lines. The watermark with the design of hidden texts or figurative pattern can attain both aesthetic and innovative features. The method is successfully implemented on the personalized stamps. It would also provide many value-added applications for secured documents.
