生物特征识别技术综述

Overview of Biometric Recognition Technology

基于生物特征识别技术的身份认证是社会高度信息化和经济全球化的需求,是政府和商业领域必不可少的重要技术.为此,介绍了生物特征识别技术的基本原理、性能指标、关键技术、研究现状和技术应用等.全面调研了指纹、掌纹、虹膜、人脸、指静脉、声纹等不同的生物特征识别技术的研究现状,比较了各种生物特征识别技术在错误率、稳定性、实用性、处理速度和仿冒程度等方面的差异.此外,针对辨认和确认2种场景分别介绍了它们在各方面的应用情况,分析讨论了生物特征融合技术、生物特征安全性问题,介绍了该领域现有的行业和国家标准.最后对生物特征识别技术的发展前景给予展望.

The identity authentication based on biometric identification technology is the demand of the development of information and economic globalization, and also one of the important technologies in governmental and commercial fields. In this paper, the fundamental principles, performance evaluation, key technologies, research status and application of biometric recognition are introduced Through the overview of the research on different biometric recognition technologies of fingerprint, palmprint,iris,face, finger-vein,and voiceprint,we compare them in term of error rate,stability,usability,processing speed,and anti-spoofing. Then their applications in various aspects for both identification and verification scenarios are illustrated; the fusion technology and security problem are discussed ; and the industrial and national standardization is introduced. Finally, the prospects of biometric recognition technologies are discussed additionally.
