Abstract

Abstract: This paper proposes a framework of copyright protection based on CA，the framework uses the algorithm of edge detection and cellular automata.First，this paper detects the edge of the image with the edge detection technology，and then uses cellular automata smooth the image，finally，accomplishes the signature verification.The experimental results show that the algorithm has high robustness，to resist cutting，rotating，noise.It is suit for the medical and military and other fields image copyright protction.

Key words: cellular automata, edge detection, copyright protection, Certficate Authority（CA）

摘要： 提出了一种认证中心控制下的版权保护框架，该框架应用了边缘检测与元胞自动机算法。首先应用边缘检测技术检测出图像的边缘点，然后应用元胞自动机对边缘点进行平滑处理，最后对平滑处理后的图像进行签名认证。仿真结果表明，该算法具有高鲁棒性，能够抵抗裁剪、旋转、噪声等攻击，适用于医学、军事等领域的版权保护。
