Abstract

The invention provides an identity authentication method. The method comprises the following steps: acquiring recorded information for an effective user, wherein, the recorded information shows the behaviors executed by effective user previously; mapping the recorded information to a plurality of dimensionalities according to an orthogonal behavioral model with a plurality of orthogonal dimensionalities, wherein, the behaviors showed by the recorded information mapped to different dimensionalities are not overlapped with each other and have no logical causal relationship; respectively sampling the recorded information mapped to different dimensionalities so as to generate an authentication questionnaire containing a plurality of authentication problems; calculating the total confidence probability P of a client as the effective user based on answers of the client to the authentication questionnaire, and outputting a positive authentication result in the event that the total confidence probability P falls into a confidence interval; and outputting a negative authentication result in the event that the total confidence probability P does not fall into the confidence interval. The invention further provides a corresponding identity authentication device.

Description

technical field

[0001] The invention relates to an authentication method and device. In particular, the present invention relates to methods and devices for identity authentication in networks. Background technique

[0002] In the current environment of online communities, games, e-commerce, etc., in order to identify valid users, security measures of customer identity authentication are usually adopted. The authentication process is actually the process of determining whether the authenticating subject (client) is who it claims to be (eg, a valid user).

[0003] Usually, in some online service systems, when customers apply for some specific services, they are usually required to reserve certain personal information data in the database, and then the authentication system designs questions or tests based on these private information to authenticate the identity of the customer. A simple example is that in some website login pages, customers are required to provide login in...
