基于生物识别的网络身份认证新方案

文章分析了现今基于生物识别技术的网络认证没被广泛应用的原因：生物特征的提取一般需要特殊的专用设备、指纹的利用比较泛滥、生物特征遗失后挂失比较困难等。文章同时对比了几种比较主流的生物特征识别技术，分析了它们各自的实用性、便捷性以及安全性，指出生物3D打印技术在未来对生物识别技术带来冲击的可能。文章提出了一种基于动态人脸识别的网络认证方案，该方案利用人脸作为网络认证的基础，通过跟踪实时人脸活动来实现实时人脸图像的采集，预防了照片攻击和视频攻击，提高了认证的可靠性和安全性。文章最后通过分析该方案的可实现性、可叠加性和安全性，并从成本等方面考虑，得出该方案性能较优的结论，同时对生物识别技术应用于网络认证进行了展望。由于生物特征具有唯一性和不可重置的特点，所以生物特征保护需要引起更高的关注，也需要更多学者做相关的研究，更好地利用生物特征。

A New Network Authentication Scheme based on Biometric Recognition

This paper analyzes the causes of today＇s network authentication based on biometric recognition has not been widely used ： the need for special equipments to extract biometric features, the rampant use of ifngerprints , and the dififculties of reporting biometric features loss. Meanwhile, this paper compares several major biometric recognition technologies to analyze the practicality, the convenience and the security. By judging from the rapid development of the Bio-3D printing technology, this paper points out that the Bio-3D printing technology may bring impact to the biometric recognition in the future. In this paper, a network authentication scheme based on face recognition is proposed ,in which faces are used as the basis for network authentication. By tracking facial activities in real time to achieve real-time facial image ,the system can prevent the photo and video attacks ,while increasing the reliability and the security of authentication . Finally the paper analyzes the implementation , the additive and the security of the scheme, draws a conclusion that the scheme has superior performance with the consideration of the cost of this scheme .This paper also looks forward to the application of the biometric recognition on the network authentication. Because of the uniqueness of the biometric features and because the biometric features cannot be resetting, more attention should be put on the biometric features protection and more related research should be done on the biometric features which can be better made use of.
