To enhance the convenience of authentication when executing an application, an application server: acquires, from a terminal, context information indicating the status of the terminal; generates, on the basis of the acquired context information, information (an authentication necessity table) pertaining to the necessity for authentication when executing the application; and transmits to the terminal the authentication necessity table and an authentication module described in the table. Then, the terminal, on the basis of the authentication necessity table and an authentication table, determines whether or not authentication is necessary before executing the application, and when it has been determined that authentication is necessary, prior to executing the application, changes the authentication module read destination to the application read destination and executes the authentication module. |
