    Abstract: 現今家家戶戶幾乎都已搭上便利的網路列車,成千上萬的資訊無時無刻都在網路上傳遞,提供人們便利的訊息,不過這也意味只需在彈指之間便可將資訊納為己有,造成許多的侵權事件。而數位浮水印就是將作者的資訊加在作品中,往後便可取出驗證,以維護作者的智慧財產權。本研究利用影像中的最高位元平面來製作視覺密碼學中的Share1,接而利用Share1與浮水印製作出與原圖一樣大之Share2。本研究產生出之Share1與Share2與原圖一樣大,有別於以往會比原圖大的缺陷,大大的減少了資訊的攜帶量。如此便可將浮水印抽象的加於影像中,驗證時只需將影像的最高位元平面取出,和作者保管之Share2疊在一起即可。相信本研究對於智慧財產的保護提供了一簡單、方便的方法。
    People use Internet much easier now, but tort problem happenedeveryday. Digital watermarking means adding the author information inthe work. When facing any controversial issue, it can protect thecopyright. This research used the most significant bit-plane as theShare1 of visual cryptography, and used the Share1 and the watermarkto produce the Share2. This research produce Share1 and Share2 whosesize equal to original image, it's not alike traditional model's sharewhose size is larger than original image. It is believed that thisresearch will enhance the copyright with convenience and simple use.
