Disclosed are a system and a method for call-to-call authentication. The system for call-to-call authentication comprises: a transmission module which transmits a call; a reception module which receives a call; and a control module which controls the transmission module to transmit a first call to a mobile terminal of a requester requesting a service, and determines that authentication for the service is successful, only if the reception module receives a second call from the mobile terminal after the first call is transmitted. |
