摘　　要：图像认证是近几年发展起来的新技术。数字水印技术作为图像认证技术的一种，近年来得到了充分的关注。本文对一种基于FUZZY-ART理论的自适应数字水印算法进行了研究，首先对宿主图像进行分块学习，挑选出适合嵌入水印的图像块，并根据学习的结果，自适应地嵌入被置乱以后的二值图像水印。本文提出的是一种基于掩码盲检测的算法，大大减少了所需要传输的额外信息。实验证明本算法可以抵抗多种恶意的攻击。Image authentication is a new technology which has been developed in recent years. As an image authentication technology, digital watermarking has been developed greatly in recent years. A digital watermarking algorithms based on FUZZY-ART is presented in this paper. Firstly, the image is divided into many blocks, and then FUZZY-ART is used to identify some of them which are adapted to be embedded by the watermark. This algorithm is based on mask blind detection, which can diminish superfluous transmitted information. Experiment results show that this algorithm can resist many malicious attacks.
