Embodiment Construction

[0091] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0092] A. System configuration

[0093] figure 1 The hardware configuration of the mobile terminal 10 that schematically shows the strength of the present invention. The mobile terminal 10 is an information processing terminal such as a cellular phone or a personal digital assistant (PDA), which is small and light enough for a user to carry.

[0094] The mobile station 10 shown in the figure includes: an IC chip 50, which uses wireless communication with an external device to drive by receiving power and has a storage function; a controller 11 for controlling all internal operations of the mobile terminal 10; a user input unit 12. Formed by keys / buttons for inputting various character strings and commands such as personal identification numbers or passwords by the user; and a display unit 13, such as a liquid crystal display (LCD), for displaying processing resu...

Abstract

A memory region on an IC card has a hierarchical structure. Each application allocated on the memory region is registered in a directory, and the memory region is managed in directory units. A personal identification code is set for each application and directory, and the access right is controlled in application units or directory units. If a mobile terminal is lost, the right to access each application in the IC card automatically disappears. Therefore, the right to access each application allocated to the memory region on the IC card is efficiently controlled.
