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.

Integrated circuit device, information processing apparatus, memory management method for information storage device, mobile terminal apparatus, semiconductor integrated circuit device, and communication method using mobile terminal apparatus

An application program relating to a process of an integrated circuit is stored in a virtual integrated circuit storage area server apparatus. Following a mutual authentication between the IC and the virtual storage area server apparatus through a portable communication function unit, the server apparatus executes the application program. Additionally, through the IC, the portable communication function unit, a wireless communication line, and a network, communicate with an IC_R/W apparatus and perform a process relating to a service in collaboration with each other.

Service providing method and integrated circuit

An IC card transmits data received from a card reading and writing apparatus to a portable terminal via an external interface without changing the received data, or after the received data is converted according to an appropriate conversion scheme or is converted into other packet data. Conversely, the IC card transmits data received from the portable terminal via the external interface to the card reading and writing apparatus via a non-contact interface without changing the received data, or after the received data is converted according to an appropriate conversion scheme or is converted into other packet data. Therefore, non-contact data communication can be performed between the information processing terminal connected to the IC card and the card reading and writing apparatus.

IC card, information processing terminal, trilateral data communication system, and method

Amount information stored in an IC chip installed in a portable terminal has been encoded, and no key is contained in the same terminal for protection against unauthorized use. On the other hand, in order to allow the information to be viewed even offline, a portion of the information can be displayed by a specific application. After a viewer application is downloaded from a service provider, followed by mutual authentication with the IC chip, the application is enabled on the terminal, and the extent viewed is registered. Therefore, the amount information stored in the IC card or IC chip can be displayed even in an offline environment.
