摘　　要：生物信息学与信息安全具有高度互补性,用生物特征来确保信息安全已经成为国内外研究的热点。为此研究了利用生物特征来生成数字水印。介绍了数字水印技术所具有的安全性、隐蔽性和鲁棒性的基本特征,讨论了当前常用的水印嵌入算法,阐述了基于在线签名的生物特征数字水印生成过程,最后给出了基于生物特征的数字水印技术的应用和研究方向。The bioinformatics are highly complementary to information security. Using biometrics to ensure information security has been a research hotspot at home and abroad. This paper investigated the generation of digital watermark, which based on biometrics. Firstly, introduced the basic characteristics of digital watermarking technology, as if, security, invisibility and robustness. Then, discussed the embedding algorithms of watermark and expounded the process of digital watermark generation,which based on the biometrics of online signature. Finally, the application field and research direction of digital watermark technology based on biometrics were given.
