Identity authentication method, device and system for dialing landline

Abstract

The invention provides an identity authentication method, equipment and system for making a fixed-line call. The method comprises the following steps: receiving by an authentication server dial request information sent by a fixed-line terminal, if pre-stored user information comprises a corresponding relation between a fixed-line terminal number identification and a user identification is judged, calculating a random sequence code according to an authentication algorism to generate first verification information, sending the random sequence code to a mobile terminal corresponding to a user, and when second verification information generated through calculation of the random sequence code by the fixed-line terminal according to the authentication algorism is received by the authentication server, determining by the authentication server whether the first verification information and the second verification information are the same, so as to verify whether the user can log in legally. According to the identity authentication method, equipment and system for making the fixed-line call, provided by the invention, the identity of the user is verified through the mobile terminal bound with the fixed-line terminal before the user uses the encrypted fixed-line service, so that illegal dialing by a secondary user is avoided, and the safety of the fixed-line service is improved.
