Identity authentication method and device and mobile terminal

Abstract

The invention provides an identity authentication method and device and a mobile terminal. The method comprises the steps that the three-dimensional information of a body part of a user is acquired through structured light; whether the three-dimensional information of the body part matches the pre-stored three-dimensional information of the body part is determined; if the three-dimensional information of the body part matches the pre-stored three-dimensional information of the body part, a variety of identity authentication methods are provided, and the target identity authentication method is determined according to the selection operation of a user; authentication information input by a user for the target identity authentication method is received, and whether the authentication information matches pre-stored authentication information is further determined; and if the authentication information matches the pre-stored authentication information, the user passes identity authentication. According to the identity authentication method provided by the embodiment of the invention, the identity authentication of the user is accurately realized through the combination of three-dimensional authentication of the user identity part and other authentication methods; the risk of being stolen and disguised of authentication through biometric information such as fingerprints, irises and the like is avoided; and the safety is improved.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to an identity verification method, device and mobile terminal. Background technique [0002] At present, in order to protect the privacy and property security of users, it is necessary to authenticate users in many scenarios. verify. [0003] However, in the process of realizing the present invention, the inventors found that there are at least the following problems in related technologies: when identity verification is performed through passwords, the setting of passwords will affect the security of authentication, complex passwords are not easy to be cracked, and security It is relatively high, but it is often difficult for users to remember; simple passwords can be remembered by users, but they are easy to be cracked and the security is not high. Moreover, once a hacker invades the password database, a large number of user passwords will be leaked. The u...
