An identity authentication method is described. The method includes, when receiving a group joining request that is sent by a first terminal and that is used for joining a trusted group, generating, by a server, a first certificate for the first terminal based on a first version number, and sending them to the first terminal. The method further includes, when determining that a second terminal is removed from the trusted group, updating the first version number to a second version number; and separately generating, by the server based on the second version number, a corresponding second certificate for a terminal not removed from the trusted group; and separately sending the corresponding second certificate and the second version number to the terminal not removed from the trusted group. In this way, during authentication, a terminal may compare a version number of the other party to perform identity authentication, thereby improving authentication efficiency.

Identity authentication method and system, server, and terminal

A security mode prompt method and apparatus where the method includes when it is determined that a terminal is currently in a first security mode, acquiring prestored first security information; receiving first verification information entered by a user, and establishing a first correspondence between the first security information and the first verification information; displaying confusion information, the first security information, and the first verification information on a screen for the user to select; receiving a selection result of the user, and determining, according to the first correspondence, whether the selection result of the user meets a preset rule; and when the selection result of the user meets the preset rule, prompting the user that the terminal is in a second security mode. Using the present disclosure, security of a terminal can be improved.
