Embodiment Construction

[0081] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0082] A. Contactless data communication system using IC card

[0083] FIG. 1 schematically shows the configuration of a contactless IC card communication system to which the present invention can be applied.

[0084] This contactless card system includes a card reader / writer 1 , an IC card 2 and a controller 3 . Data is sent and received between the card reader / writer 1 and the IC card 2 in a contactless manner using electromagnetic waves. That is, the card reader / writer 1 sends a predetermined command to the IC card 2, and the IC card 2 performs processing corresponding to the received command. Then, the IC card 2 transmits response data corresponding to the processing result to the card reader / writer 1 .

[0085] The card reader / writer 1 is connected to the controller 3 through a predetermined interface (for example, an interface compatible with th...

Abstract

By performing copying or backup of value information electronically stored in a memory area, it is possible to smoothly perform movement of value information between terminals. An archive file containing a terminal ID of a movement destination is created from data in an IC card and stored in a predetermined storage place so as to safely perform backup of value information. Moreover, the archive file can be spread only by a device specified by the terminal ID. Moreover, access to a file and a directory in the IC card is managed by a counter. After the archive file is archived in the storage place, the counter value of the original file is erased.

Description

technical field [0001] The present invention relates to an information management device and an information management method for managing access to information stored in a relatively large-capacity memory area. Specifically, the present invention relates to an information management device and an information management method for storing electronic value information in a memory area and performing secure information communication for electronic payment and the like. [0002] More specifically, the present invention relates to an information management device and an information management method for allocating various files in a memory area and managing information for service operations. In particular, the present invention relates to an information management device and an information management method for copying or backing up value information electronically stored in a memory area and smoothly transferring value information between terminals. Background technique [00...
