摘要
在人员身份识别系统设计中,往往利用了生物特性信息,当前广泛使用的一些识别方法的识假率和拒真率相对较高.指静脉识别利用手指流动血液中的血红蛋白对特定波长光线的吸收从而形成唯一的静脉血管图像,具有活体性、效率高、适应性好等特点.利用这一生物特性,设计了指静脉身份识别系统,对采集到的数据进行分析、处理、加密,并与事前录入的指静脉模板信息进行匹配,最后通过网络传输至服务器完成身份识别和认证工作.试验结果表明,基于指静脉的生物特征识别具有速度快、不可伪造等优点.
Biological characteristics are usually used in the design of identification system. The false acception rate（FAR） and false rejection rate（FRR） are relatively high of some identification methods that are widely used. Finger-vein recognition forms unique figure of vein, exploiting absorption of specific wavelength light by hemoglobin in the flowing blood of fingers. It is high-efficient, well-adaptive and living body needed. According to these features, this paper design a finger-vein identification sys- tem, in which the collected data are analyzed, encrypted, then matched to pre-entered finger vein templates. Finally, identification and authentication are achieved by information exchange between frontend equipment and network server. Experiments results show that finger-vein identification operates fast and can not be cheated.
