在數位資訊的時代，數位出版品已經是當今出版商的重點發展對象，但在數位出版品蓬勃發展時，著作權的保護機制卻發展的相當緩慢。如何保護數位出版品在發行的同時，確保產品內容在遭到盜用或修改的情況下，能更快速的分辨著作權之歸屬，使其損失降至最低，即是此時所刻不容緩的事情。而在眾多的保護機制中，數位浮水印為大多數出版商用來保護自家出版品所廣為使用的技術之一，但需注意的是，在利用數位浮水印保護出版品時，多少會破壞到出版品的品質，如此一來便降低了出版品的閱讀性與其價值。本研究將針對數位影像，利用直方圖位移法並配合預測法來製作易碎型數位浮水印，降低出版品在嵌入數位浮水印時所產生的破壞，且可將受保護的影像回復到原來的影像。本研究除了能保護出版品的著作權外，更可提升出版品的閱讀性，進而提升產品價值。In the era of digital life, digital publication is one of the major developments of today's publishers. However, the copyright protection mechanism for digital publications does not follow up. How to protect the ownership after distributing the digital publications has become a primary issue. Besides, the technique to identify the ownership of stolen or modified content so that the losses can be minimized is the urgent task at this time. Among all sorts of protection mechanisms, digital watermarking is one of the most widely used techniques for publishers to protect their own publications. However, it must be noted that using digital watermarking to protect digital publications will downgrade the quality of them. This would have reduced the publication's readability and its value. This research will focus on the digital images. By using the histogram shifting and prediction technique, the secret message can be inserted and cause only insignificant distortion. As the result, our research can protect copyright of the publication and enhance its value by maintaining its readability at the same time.
