中文摘要 | 數位浮水印是近來常用於保護智慧財產權的技術之一,黃明祥等人曾提出一種基植於單向函數軍作的HCH浮水印機制[14],雖然擁有在空間域執行快速方便的優點,但是卻無法抵抗位元互補(bit complement)攻擊;本文主旨在整合人類視覺系統(HVS)之特色以提高HCH浮水印機制之強韌性,並且透過最小可察覺失真度(MND)之功能來進行可調式浮水印之嵌入,以提高浮水印之容量。實驗證明所提出之可調式浮水印機制不僅可以抵禦位元互補攻擊,對於最小位元破壞攻擊和常見之JPEG/JPEG2000壓縮、放大縮小、及切割等影像處理攻擊都有良好的浮水印萃取辨識成果。 |
英文摘要 | Digital watermarking techniques have been proposed for the copyright protection of digital images. A HCH watermarking technique [14] based on one-way hash function could be effectively removed by bit complement attack without knowing any secret information. This main goal of our method is to improve HCH method and a robust watermarking scheme based on the characteristics of human visual system was proposed to resist such an attack; the experimental results approve that it is not only immune to bit complement attack, but also to the other common image processing operations such as JPEG/JPEG2000 compression, resizing and cropping, and so on. |
