[0064] Therefore, next, the data control system according to the first embodiment of the present invention will be explained when as Figure 4B As shown, when there is an inconsistent state between the index area and the service area, it can restore a consistent state.

[0065] Figure 5 is a block diagram illustrating a data control system according to a first embodiment of the present invention.

[0066] refer to Figure 5 , the data control system according to the first embodiment includes an information processing terminal 100 , a card reader / writer 150 , a control server 200 , and a security module 250 . pay attention to Figure 5 In , the only information processing terminal shown is the information processing terminal 100, but the data control system according to the first embodiment may include a plurality of information processing terminals.

[0067] By using a magnetic field (carrier) of a specific frequency such as 13.56 MHz, the information processing terminal ...

[0129] In the foregoing explanation of the first embodiment, the configuration in which the control server 200 determines the presence of an inconsistent state by checking the existence of a service area corresponding to each of at least one link information item, wherein the at least one link information item The information items are stored in the IC chip 102 (transfer destination IC chip) of the information processing terminal 100 to which data transfer has been performed from the transfer source IC chip. The control server 200 then resolves the inconsistent state. However, in the case where data transmission has already been performed from the transmission source IC chip (for example, in which incomplete service data that has not been correctly updated is stored) to the IC chip 102 (transmission destination IC chip) of the information processing terminal 100 , it may happen that the service data item stored in the IC chip 102 (transfer destination IC chip) of the informati...

[0137] In the first and second embodiments described above, the configuration is explained in which the control server resolves the state where the inconsistency exists in the index area in the IC chip (transfer destination IC chip) of the information processing terminal 100 and between service areas. However, the embodiment of the present invention is not limited to the configuration in which the control server resolves the state of inconsistency existing between the service area and the link information item stored in the IC chip in the information processing terminal (Transfer destination IC chip) in the index area. For example, the information processing terminal itself may be the main element in recovering the inconsistency between the service area and the link information item stored in the index area in the information processing terminal.

[0138] The information processing terminal restores consistency between the service area and the link information item stored in ...

Abstract

There is provided a data control system that includes a control server and an information processing terminal equipped with a non-contact type IC chip. The information processing terminal includes a chip memory and a consistency check request portion. The chip memory includes at least one service area that stores a service data item and an index area that stores a link information item for accessing the service area. The consistency check request portion transmits a consistency check request.; The control server includes a data acquisition portion that acquires the link information item according to the check request, an area determination portion that determines whether the corresponding service area exists for each link information item, a reading portion that reads the determined service area, and a data update portion that, if the service area could not be read, updates the link information item with information not indicating any access destination.

Description

technical field [0001] The present invention relates to a data control system, a control server, a data control method, and a program. Background technique [0002] In recent years, information processing terminals capable of non-contact communication with card readers / writers have become widely used, such as being provided with a non-contact type integrated circuit (IC) card (hereinafter referred to by its common name "smart card"). "Calling) or mobile phones with non-contact type IC chips, etc. [0003] IC chips provided with tamper resistance enable the aforementioned information processing terminals capable of non-contact communication with card readers / writers to securely transmit, receive and update data such as electronic money etc. for which data falsification is a problem. Therefore, the provision of services using information processing terminals capable of non-contact communication with card readers / writers is spreading throughout society. In addition, with the ...
