生物识别技术与应用

生物识别技术可以用来鉴别身份或证明身份，主要包括虹膜识别、视网膜识别、面部识别、指纹识别、DNA识别、气味识别、签字识别和声音识别等，其中指纹识别是最常用的一种．生物识别技术在人类的物理生存空间和虚拟生存空间具有广泛的应用前景。在介绍生物识别原理的基础上。讨论了两种类型生物识别技术，一种基于生理特征：虹膜识别、视网膜识别、面部识别和指纹识别；另一种基于行为特征：签字识别和声音识别。

The technology and application of biometrics

Biometrics technology can be used for either identification or authentication purposes. The most commonly known method of biometric identification is fingerprint biometrics. Other biometrical methods of identification include iris and retinal scans, facial feature recognition, fingerprinting, signature dynamics and voice verification. These technologies have many potential uses in the physical living space and virtual living space. Based on biometrical recognition principles, two types of biometrics technology are discussed in this paper. One is founded on the physiological features; iris and retinal scans, facial feature recognition, fingerprinting. The other establishes the behavior features: signature dynamics verification and voice verification.
