SYSTEM AND METHOD FOR AUTHORIZING MOBILE TERMINAL CONNECTING TO EXTERNAL DEVICE, AND EXTERNAL DEVICE AUTHORIZING MOBILE TERMINAL

摘要

PURPOSE: An authentication system and an authentication method for a portable terminal which is connected to an external device, and an external device authenticating a portable terminal are provided to limit the number of portable terminal which uses an exterior device. CONSTITUTION: An authentication system for a portable terminal comprises a portable terminal (100), an external device (200), and an authentication server (300). An external device comprises a docking interface, an identification code acquiring unit, and a controller. A docking interface docks with a portable terminal. An identification code acquiring unit acquires an identification code of a portable terminal which is docked with and an identification code of an expansion device. A controller transmits an authentication request including an identification code of a portable terminal or an identification code of an expansion device to an authentication server and performs an authentication operation corresponding to a response about an authentication request which is transmitted from an authentication server. An authentication server authenticates the usage of an external device of a portable terminal when an authentication request is transmitted from an exterior device of a communication unit and transmits a response about an authentication request to an external device. [Reference numerals] (1) Docking connect; (2) Acquire the identification code of a portable terminal and the identification code of an external device; (3) Request the authentication of the portable terminal (The identification code of the portable terminal + The identification code of the external device); (4) Execute the authentication of the portable terminal; (5) Respond about an authentication request; (6) Execute an authentication operation
