  • Publication number: 20100169554
    Abstract: A terminal apparatus acquires setting information for controlling whether a storage area held by the non-volatile storage medium is to be used or not, from an external apparatus connected via a network, when the terminal apparatus is activated. The terminal apparatus updates area definition information defining the structure of storage areas in the non-volatile storage medium so that the storage area the use of which is restricted is in a state which cannot be recognized by the operating system, if the acquired setting information indicates that the use of the storage area is restricted. The terminal apparatus performs activation processing of the operating system after the update processing of the area definition information ends, if the acquired setting information indicates that the use of the storage area is restricted.

  • Publication number: 20100077485
    Abstract: An apparatus having a communication section operable to communicate with a central apparatus, and a storage control section operable to control writing onto, and reading from, a storage medium. The apparatus receives a control command transmitted from the central apparatus. The apparatus, if the received command is a security command, acquires process information indicating information on the security process. The apparatus transmits the process information acquired to the central apparatus. The apparatus, if the received command is a security command, executes the security process. The apparatus, if the received command is an inquiry command, acquires the status of the execution of the security process. The apparatus transmits the security process execution status acquired to the central apparatus. The apparatus, if the execution of the security process is completed, transmits the fact that the execution of the security process in the storage medium is completed to the central apparatus.
