基于人体生物特征的身份鉴别技术发展概况

Biometric identification techniques

生物特征身份鉴别方法是根据人体各器官或个人行为之间的差异来鉴别个人身份。这种身份鉴别方法具有可靠性、防伪性、方便性和安全性的特点。随着计算机技术的迅速发展 ,生物特征鉴别技术将在军事和人们的日常生活等各方面得到广泛的应用。该文对各种不同生物特征鉴别方法的发展概况做了简要的介绍 ,对不同方法的识别原理、特征、应用的优点及局限性等也做较详细的论述。同时针对改进身份鉴别系统的误识率问题讨论了综合特征鉴别方法。对生物特征身份鉴别技术的应用前景和发展方向也做了分析。

Biometric identification techniques deal with the identification of individuals based on their biological or human behavioral characteristics. Biometric identification methods should be reliable, anti counterfeit, convenient and safe. As the development of a computer, biometric identification techniques will be used widely either in the martial area or in our daily life. The paper summarizes biometric identification techniques. Also it fully discussed the identification principle, character, the advantages and disadvantages of different methods. Moreover, the character integrated method was discussed to improve the false acceptance ratio of biometric identification techniques. The prospects and development of those methods are also analyzed.
