    Summary: 對於數位內容的服務者和供應商,數位多媒體內容的保護,已經成為一個重要的議題。現今數位浮水印被定義為實現版權保護的重大技術。但是,實作一個具有強韌性之數位浮水印是有難度的。本論文提出一個強韌數位浮水印的演算法,我們結合了離散小波轉換和奇異值分解等技術。我們會利用影像中的邊界資訊再將數位浮水印嵌入於影像的邊緣特徵裡。此外,我們利用粒子群最佳化演算法求取嵌入與取出數位浮水印之最佳調整因子。實驗結果證實,本論文的方法具有高度的不可視性,而且對於多樣性的影像處理攻擊皆有很好的抵抗效果。 Protection of digital multimedia content is an important issue for server and supplier of digital content. Digital watermarking is an important technique for copyright protection of content. However, it is difficult to implement a robust watermarking scheme. In this paper, we propose a robust digital watermarking scheme which hybrids discrete wavelet transform and singular value decomposition. The edge information in an image is utilized to embed the watermark. In addition, the particle swarm optimization technique is used to search the appropriate scaling factor. Experimental results are provided to illustrate that the proposed approach is able to withstand a variety of image-processing attacks.
