Abstract:	在此論文中，我們基於影像內容的影像認證架構，提出一個彩色影像認證的技術。這個方法以影像的邊緣資訊作為影像的特徵值，並利用這個特徵值作為驗證碼。根據實驗的結果，我們的方法只需要很小的認證碼就可以正確地偵測並標示出被惡意修改的區域。我們的方法也可以透過門檻值的設定來調整系統的強韌度，能夠有效地分辨合法與非法的影像修改。 One novel color image authentication schemes for color images are proposed in this paper. The edge information of color images is exploited to design the authentication codes. Experimental results demonstrate that the proposed method not only verifies the authenticity and the integrity of color image, but also locates the illegal modifications. Additionally, by setting different threshold values, malicious manipulations can be prevented while allowing incidental manipulations.
