As a novel identification technology , biometrics , which uses the inherent traits of human body to automatically identify individuals , has emerged as the times required 生物特征识别技术是利用人体固有生物特征来进行身份识别的技术,相对于传统的基于密码和ic卡的身份识别技术,具有更高的安全性、可靠性和有效性。
Face recognition ( fr ) has become an increasingly popular subject in the field of biometrics . more and more researchers in computer vision and pattern recognition pay their attention to this field 人脸识别技术是目前生物特征识别中最受人们关注的一个分支,是计算机视觉与模式识别领域非常活跃的一个研究方向。
Traditional personal identification methods can not satisfy our demand with the development of modern information society . biometrics is a kind of science and technology for personal identification 传统的身份验证方法已经不能满足现代信息社会的要求,生物特征识别技术以其特有的安全性,可靠性和有效性等越来越受到人们的重视。
Biometrics is a kind of science and technology using individual physiological or behavioral characteristics to verify identity . it provides a highly reliable and robust approach to the identity recognition 生物特征识别是一项利用人类特有的生理或行为特征来进行身份识别的技术，它提供了一种高可靠性、高稳定性的身份鉴别途径。
However , traditional password , pin and access card all have disadvantages and can ’ t meet the requirement of secrecy . recently biometric technology has emerged as an ideal solution to this growing problem 原有的基于智能卡、身份证号码和口令的识别技术已不能满足要求,而近些年来发展起来的生物特征识别技术可以很好的解决这个问题。
The main work in this paper as follows : the evolutionary development and application background of identification technology using biometric feature have been described , especially of fingerprint - based identification 论文的主要工作如下：阐述了生物特征识别的发展历史、应用背景，并着重介绍指纹识别技术的发展、应用及研究现状。
Compared with the other biological characteristic recognitions ( fingerprint recognition , facial recognition voice recognition , etc . ) , iris recognition has the following characteristics : stability , high reliability , non - contact 它与其他生物特征识别技术(指纹识别,面部识别,声音识别等)相比具有以下几个特点:稳定性、高可靠性和非接触性。
At last , in order to further explore the practicality of fusion pattern recognition , we use multimodal biometrics , which is based on fingerprint and hand geometry to validate the availability of the third method 最后，引入基于指纹方向场和手形特征的多模态生物特征识别实验对上面的决策层融合识别方法进行验证，为信息融合在模式识别方法中的实用化做出一点探索。
The software can strengthen the security of pc and has been sold as a production . the following is my major work : the paper review the background of biometrics , classification of biometrics technology and the application of biometrics 针对生物特征识别技术潜在的巨大市场而国内相关的商用软件的局限性，本课题开发了一种利用人脸特征进行计算机系统登陆，为加强pc机安全性、防止非法入侵的系统软件? ? faceok 。
Because fingerprint recognition is the leading biometric technology in terms of market share at present , the research on biometric key algorithm based upon fingerprint , i . e . , fingerprint key algorithm has a vast market outlook and an important practical value 由于指纹识别是目前市场占有率最高的一种生物特征识别技术,因此研究基于指纹特征的生物密钥算法,即指纹密钥算法,具有良好的市场前景和重要的实际意义。
