User credibility authentication system and method based on user behaviors

Abstract

The invention discloses a user credibility authentication system and method based on user behaviors. The system comprises a user identity and behavior model determination module, a user behavior collection module, a user behavior mining module, a user behavior sequence matching and credibility authentication module and a local security policy module. The method comprises the steps as follows: the user behavior mining module performs behavior mining on user behavior logs; a personal user behavior characteristic sequence is established; the user behavior sequence matching and credibility authentication module performs sequence similarity calculation on the personal user behavior characteristic sequence and a to-be-matched sequence, so that a user credibility grade is obtained, and a corresponding security policy is started using. According to the invention, a sequence pattern mining manner is adopted to collect real-time user behaviors so as to establish the to-be-matched sequence, the similarity matching of the behavior sequence is performed, accordingly, the real-time user behaviors are subjected to credibility authentication, the accurate rate of authentication is improved, and enterprise and personal property safety is guaranteed.

Description

technical field [0001] The invention relates to electronic commerce, in particular to a user credibility authentication system and method based on user behavior. Background technique [0002] With the rapid development of network technology and information technology, online transactions have increasingly become a new business model, and more and more enterprises and individual users rely on e-commerce for fast and efficient transactions.

[0003] Nowadays, in the most important online payment link in e-commerce, the identification of user identity is usually realized through account / password verification, account binding and other authentication methods. However, due to the inherent openness and resource sharing of the network, account / password Passwords are often stolen illegally. Therefore, the security problems of online transactions are becoming more and more prominent. The traditional account / password verification and account binding authentication methods are obviously unable to meet the current security requirements. How to build a credible The transaction environment, ensuring the credibility of user identities and behaviors, is receiving more and more attention
