Patent ID: 7742604

Claim:
A mobile terminal apparatus comprising: a semiconductor integrated circuit device having: (a) a memory region; (b) a wireless interface for enabling the semiconductor integrated circuit device to perform wireless communication with an external apparatus; and (c) a wired interface for performing wired communication with the semiconductor integrated circuit device; one or more applications allocated to the memory region, wherein the right to access each application is controlled by a personal identification code; user input means for inputting, from a user, the personal identification code and other data; checking means for: (a) transferring, via the wired interface, the personal identification code input from the user input means to the semiconductor integrated circuit device; and (b) checking the transferred personal identification code with a personal identification code for each application allocated to the memory region; access-right control means for giving, as a result of checking by the checking means, a right to the user to access the application in which the personal identification codes match each other; wherein the access-right control means: (a) sets each application for which the personal identification code is set to be inaccessible in a default setting; (b) in response to the personal identification code input from the user matching the set personal identification code, sets the corresponding application to be accessible; (c) in response to the personal identification code input from the user matching a set additional personal identification code, sets all applications in the corresponding memory region to be accessible; and (d) sets all applications to be inaccessible when a predetermined period of time elapses.
