摘　　要：基于指纹生物统计数据的变换,介绍一种信息安全应用的数字水印自适应隐藏技术。把指纹的节点数据隐藏到视频图像中,并可以安全地传输到接收端。通过密钥,隐藏的指纹数据可以从被传输的图像中精确提取出来。当视频信号是面部图像时,该技术附加一个标识来管理用户。与其它方法比较,该技术能抗击多种干扰信号的篡改攻击。Based on fingerprint biometric data transformation, the paper introduces a digital watermarking adaptive hiding technology applied to information secure field. The method hides fingerprint minutiae data in video image, and securely transfers to receiving port. The hidden fingerprint data are extracted accurately from the carrier image by a secret key. When video image is a face image, the method provides an additional cue to authenticate user. In contrast with other methods, this method can also tolerate several attacks on the carrier image.
