An authentication system includes: a server apparatus; a terminal device; and an authentication device connected to the terminal device and used for authentication when establishing a session between the terminal device and the server apparatus. The server apparatus has an authentication request data creating unit configured to create authentication request data to authenticate the terminal device, and a sending unit configured to send authentication request data. The terminal device has a receiving unit configured to receive authentication request data, an authentication reply data creation requesting unit configured to request the authentication device to create authentication reply data, and a sending unit configured to send the authentication reply data. The server apparatus further has: an authentication processing unit configured to authenticate the terminal device based on the authentication reply data, and as a result of authentication, data is sent to the terminal device when the terminal device is authenticated.

Authentication system, server apparatus and authentication method

The present invention makes it possible to connect to and communicate with a connect destination by using a temporary number. In the present invention, a temporary number user terminal () registers a temporary number acquired from a SIP account server () in a SIP proxy server (), and connects to and communicates with a connected user terminal () by using the temporary number. After the communication is finished, the temporary number is unregistered from the SIP proxy server (), thereby disabling a connection from the connected user terminal (). Also, connection conditions are provided by specifying the validity period of connection using a temporary number, the number of times connection can be made, the connect destination to which connection can be made, and the like, and only those calls which meet the connection conditions are accepted, thereby making it possible to restrict the uses of the temporary number.
