In this paper, an image authentication technique by embedding each image with a signature so as to discourage unauthorized copying is proposed. 本文提出了一種圖象認證技術(shù)，通過(guò)在圖像中嵌入簽名，以防止未被授權的拷貝。
These standardized authentication techniques are often ample for organizations holding low-risk data, but they are not robust enough for companies handling high-risk data. 這些標準的認證技術(shù)對擁有低風(fēng)險數據的單位而言是夠了，但對要處理高風(fēng)險數據的公司來(lái)說(shuō)還不夠保險。
