In this paper, an image authentication technique by embedding each image with a signature so as to discourage unauthorized copying is proposed. 本文提出了一种图象认证技术,通过在图像中嵌入签名,以防止未被授权的拷贝。
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. 这些标准的认证技术对拥有低风险数据的单位而言是够了,但对要处理高风险数据的公司来说还不够保险。
