本研究的目的是強化數位圖像中頻率域浮水印對抗攻擊的能力,其方法是利用各種攻擊方式對嵌有浮水印的圖像進行訓練,並透過基因演算法進行參數優化,以得到最強健的結果。
首先,本文將介紹數位浮水印及基因演算法,接著探討各種對抗攻擊的技術其原理與優缺點。由於大部分的抗攻擊技術僅適合對抗某種類型的攻擊,本文將針對此問題提出能對抗多種類型攻擊的方案,其方法是在嵌入過程中應用基因演算法,對圖像施以多種模擬攻擊並將的結果納入評比。文章最後將呈現實驗方式及實驗結果。
Application for robust watermarking is one of the major branches in digital rights management (DRM) systems and related researches. Based on existing metrics to evaluate the applicability of robust watermarking, it is generally agreed that three metrics, including the quality of watermarked contents, the survivability of extracted watermark after intentional or unintentional attacks, and the number of bits embedded, need to be considered. However, these three metrics conflict with each other. In this paper, in addition to quality and survivability discussed in literature, we take the number of embedded bits into account, thus adding the flexibility in implementation. With the aid of genetic algorithm, we designed an applicable implementation that will obtain the reasonable quality, acceptable survivability, and practical capacity after watermarking. Simulation results present the practical implementation and possible application of the proposed algorithm.
