Abstract:

 In order to prevent network fraud and identity theft and to increase authentication security,  an intelligent authentication method based on neural network and multi\|factor was improved. Based on analysis of the composing and distinguishing of identification, this method focuses the customers action.An application model which can be used in e\|commerce system is designed. Resolved the problem of traditional authentication method which depends on a few of identity factors， identity theft can be prevented, security of authentication is increased.

Key words: neural network, multi\, factor, authentication, back propagation neural network, e-commerce
