摘要
生物认证是根据生理和行为来识别或验证一个有生命个体的自动方法,涉及人类的两类生物特征:一类是生理学上的特征,例如指纹、脸型、虹膜等;另一类是行为特征,例如步态、笔迹、声音等。生物认证系统由数据采集,数据传输,数据处理,样本数据库的建立、匹配、认定等几个部分组成。目前已经开发使用的生物特征识别技术有多种,在侦查实践中,多种生物特征采用信息融合的方法可以使识别精度得到提高。
Biometric identification is an automatic way of identifying or verifying a living individual according istics, such as fingerprints, faces, iris, etc ; another is behavioral characteristics, such as paces, handwriting, voices, etc. Biometric identification system consists of the following parts ： data collection, data transmission, data processing, the establishment, match and cognizance of sample data base, etc. At present, many biometric identification techniques have been developed and adopted. In the practical investigation, the method of information merging can greatly improve the correctness of identifying mass of biometric characteristics.
