Abstract: 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 fingerprints, and the difficulties 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.
