Summary:	隨著網際網路與數位多媒體的蓬勃發展，數位多媒體的著作權保護與內容認證已然成為一個急需解決的問題。數位浮水印技術便是一種有效的技術用以保護數位多媒體的版權。本論文提出一個以區塊式奇異值分解為基礎之浮水印技術，並透過遺傳演算法對浮水印嵌入強度進行最佳化。實驗結果顯示，我們提出的方法不只改善嵌入浮水印後的影像品質，同時亦提高了浮水印對抗各式攻擊的強韌性。 With the development of Internet and multimedia technologies, multimedia copyright protection and content authentication have become serious problems that need to be solved urgently. Digital watermarking has been regarded as an effective solution to protect various kinds of digital contents against illegal use. In this paper, we present an improved singular value decomposition-based watermarking technique using genetic algorithm. Experimental results are provided to illustrate the proposed approach is able to withstand a variety of image processing attacks.
