摘要 數位浮水印是近來常用於保護數位媒體智慧財產權的技術之一,黃明祥等人[15]曾提出一種基植於單向函數運作的HCH 浮水印機制,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補全(bit complement)攻擊[4];本文主旨在透過人類視覺系統(Human Visual System, HVS)感知模式以提高HCH 浮水印機制之強健性(robustness),並且透過最大可察覺失真度(Maximum Justiceable Distortion, MND)之功能來進行可調式浮水印之嵌入,以提高嵌入浮水印之容量。實驗證明所提出之可調式浮水印機制不僅可以抵禦位元補全攻擊,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。
Digital watermarking techniques have been proposed for the copyright protection of digital images. An HCH watermarking technique [15] based on one-way hash function could be effectively removed by bit complement attack by Chou [4] without knowing any secret information This main goal of the proposed method is to improve the robustness and capacity of the HCH scheme, a robust watermarking scheme based on the characteristics of human visual system (HVS) is 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.
