Abstract: A user information management unit of a terminal generates a management number for respective users. A terminal to terminal communication unit communicates with another terminal through ad hoc communication, acquires a unique user ID set for the other user, and stores the user ID in a friend information storing unit. The data generated in a data generation unit is transmitted to a server from a sending unit along with a destination user ID selected from user IDs stored in a friend information storing unit. A reception unit in the server stores the transmitted data in a data storing unit for each destination user ID. When the server receives a connection request from a terminal, a connecting user information acquisition unit in the server identifies a user ID of a connection origin and a data retrieving unit transmits the data to the terminal by retrieving a data storing unit based on the user ID, indicating the user requested for the connection as a destination.
