Description

  The present invention relates to a technique for managing a usage history of an IC token mounted on a mobile communication terminal such as a mobile phone or a smartphone.

  Currently, mobile communication terminals such as mobile phones and smartphones are designed to be equipped with various IC tokens. Here, an IC token means a device to which an IC card technology is applied. For example, in a third generation mobile phone system that is widely used worldwide, an IC token is used as a mobile phone subscriber authentication device. One of these is a SIM (Subscriber Identification Module) card.

  Moreover, many recent mobile communication terminals have built-in short-range wireless communication devices in which IC chips of non-contact IC cards used for transportation and electronic money are modified for mobile communication terminals. As such a short-range wireless communication device, a FeliCa (registered trademark) mobile IC chip is well known.

  Furthermore, many recent mobile communication terminals can use a memory card such as an SD card or a microSD card as an auxiliary recording device, and a secure memory card mounted with an IC chip for an IC card has been developed as an IC token. Yes.

  As described above, since various IC tokens have been developed, a single mobile communication terminal can be equipped with a plurality of IC tokens. In many commercially available mobile communication terminals, SIM tokens are used as SIM tokens. A card, a short-range wireless communication device, and a secure memory card can be installed.

  The IC token installed in the mobile communication terminal is used for applications corresponding to the IC token, and when some trouble occurs, so that the cause analysis of the trouble and transaction analysis using the IC token can be performed, It is necessary to store an IC token usage history indicating information such as which IC token is used, which application, when and what work.

  Some IC tokens operate independently, but in many cases, the IC token is connected to a mobile communication terminal or a server on the network via the mobile communication terminal depending on the use of the IC token. connect. For this reason, the usage history of IC tokens mounted on the mobile communication terminal is generally stored in a server on the network or the memory of the mobile communication terminal.

  For example, Patent Document 1 describes that a transaction history of electronic money using an IC token is stored in a server. Patent Document 2 describes that personal information and communication usage information read from an IC token are stored in a nonvolatile memory of a mobile communication terminal.

  However, if the usage history of the IC token mounted on the mobile communication terminal is stored in a server on the network, the usage history of the IC token cannot be referred to unless the server can be accessed, and the mobile communication terminal If the usage history of the IC token mounted on the mobile communication terminal is stored in the memory of the mobile communication terminal, the usage history of the IC token cannot be referred to when the mobile communication terminal fails.

  Considering this, it is conceivable that the IC token usage history is stored in the IC token itself as in Patent Document 3, but if the IC token usage history is stored in the IC token itself, it is a matter of course. When the IC token breaks down, the IC token usage history cannot be referred to.

FIG.

  In the present embodiment, the mobile communication terminal 1 is a terminal device having a public wireless communication function, and specifically means a mobile phone, a smartphone, a tablet computer, and the like.

  The mobile communication terminal 1 according to the present embodiment is designed so that an IC token 2 which is a device to which an IC card technology is applied can be mounted, and the substrate of the mobile communication terminal 1 illustrated in FIG. As the token 2, a short-range wireless communication device 2b conforming to NFC (Near Field Communication), which is an international standard for short-range wireless communication having a communication distance of about 10 cm, is mounted.

A secure memory card 2c, which is a memory card on which an IC chip for an IC card is mounted, is mounted on the mobile communication terminal 1. In addition, the present applicant has already sold “TinySmart (registered trademark)” corresponding to “MULTIS (registered trademark)”, which is a high-security operating system for IC cards, as such a secure memory card 2c. .

  As shown in FIG. 2, the mobile communication terminal 1 includes a processor 1a on which a CPU, a RAM, a ROM, and the like are mounted. The processor 1a includes a wireless communication circuit 1b that performs processing related to public wireless communication, a time In addition to the above-mentioned SIM card slot 1g and memory card slot 1h, a short-range wireless communication device as an IC token 2 2b is connected. Further, the SIM card 2a is connected to the processor 1a of the mobile communication terminal 1 via the SIM card slot 1g, and further, the secure memory card 2c is connected via the memory card slot 1h.

  The mobile communication terminal 1 according to the present embodiment is a terminal device developed so as to synchronize usage histories between IC tokens 2 mounted on the mobile communication terminal 1, as shown in FIG. Synchronizing means 10 is provided as means for synchronizing at least the usage history between the IC tokens 2. The synchronization means 10 of the mobile communication terminal 1 is realized by a computer program that runs on the processor 1a of the mobile communication terminal 1.

  First, the usage history stored in the IC token 2 will be described. FIG. 4 is a diagram for explaining the usage history stored in the IC token 2.

  FIG. 4 (a) is a diagram for explaining the usage history stored in the IC token 2. As shown in FIG. 4 (a), one IC token 2 has a history of usage of the IC token 2. A usage history is stored, and further, usage histories of other IC tokens 2 mounted on the mobile communication terminal 1 are stored.

  FIG. 4B is a diagram for explaining a usage history stored in the SIM card 2a. Taking the SIM card 2a as an example, as shown in FIG. 4B, in addition to the usage history of the SIM card 2a, the SIM card 2a includes the usage history of the short-range wireless communication device 2b, and the secure memory card 2c. Usage history is stored.

  The own usage history stored in the IC token 2 is obtained by the reader / writer that communicates with the application installed in the mobile communication terminal 2 or the IC token 2 when the application of the mobile communication terminal 1 uses the IC token 2. It is written into the memory of token 2.

  For example, the SIM card 2a is used by the communication function of the mobile communication terminal 1, and the communication history of the mobile communication terminal 1 is written in the memory of the SIM card 2a as the use history by the communication function of the mobile communication terminal 1. .

  Also, the short-range wireless communication device 2b is used for electronic money, for example, and a usage history related to electronic money is written into the memory of the short-range wireless communication device 2b by the electronic money terminal.

  Furthermore, the secure memory card 2c is used for, for example, an electronic book, and the usage history of the electronic book is written in the IC chip memory for the IC card mounted on the secure memory card 2c.

  On the other hand, the usage history of another IC token 2 stored in the IC token 2 is written by the synchronization means 10 provided in the mobile communication terminal 1. For example, the usage history of the short-range wireless communication device 2b and the secure memory card 2c is written to the SIM card 2a by the synchronization unit 10.

  In order to synchronize usage histories, it is necessary to identify usage histories of other IC tokens 2 stored in the IC token 2, and in this embodiment, at least the other IC tokens 2 The unique number of the IC token 2 corresponding to the usage history is added to the usage history.

  Next, contents for synchronizing the usage history between the IC tokens 2 will be described. FIG. 5 is a diagram for explaining the contents of synchronizing the usage history between the IC tokens 2.

  Synchronizing the usage histories between the IC tokens 2 means that the usage histories stored in the IC tokens 2 are made identical between the IC tokens 2.

  As illustrated in FIG. 5, the mobile communication terminal 1 of the present embodiment includes the short-range wireless communication device 2b, the SIM card 2a, and the secure memory card 2c as the IC token 2, so that the mobile communication terminal The first synchronization unit 10 stores the usage history of the short-range wireless communication device 2b in the SIM card 2a and the secure memory card 2c, respectively.

  The synchronization means 10 of the mobile communication terminal 1 stores the usage history of the SIM card 2a in the short-range wireless communication device 2b and the secure memory card 2c, respectively. Furthermore, the synchronization means 10 of the mobile communication terminal 1 stores the usage history of the secure memory card 2c in the SIM card 2a and the short-range wireless communication device 2b, respectively.

  FIG. 6 is a flowchart for explaining processing executed by the synchronization means 10 of the mobile communication terminal 1. As shown in FIG. 6, when a synchronization trigger serving as a trigger for starting the synchronization of the usage history between the IC tokens 2 occurs in the mobile communication terminal 1 (S1), the synchronization means 10 of the mobile communication terminal 1 Performs a synchronization process (S2) of reading the usage history of the IC token 2 for each IC token 2 mounted on the mobile communication terminal 1, and storing the read usage history in another IC token 2.

  The synchronization trigger that is a trigger for starting the synchronization of the usage history between the IC tokens 2 may not be one type, and a plurality of types of triggers can be used as the synchronization trigger. For example, when the power of the mobile communication terminal 1 is turned on / off or when the communication area is changed, the synchronization trigger can be used.

  Further, since the IC token 2 mounted on the mobile communication terminal 1 includes the removable IC token 2 such as the SIM card 2a and the secure memory card 2c, the removable IC token 2 is attached to the mobile communication terminal 1. You can also use that mounted as a synchronization trigger. When the fact that the detachable IC token 2 is mounted on the mobile communication terminal 1 is used as a synchronization trigger, the usage history of the period during which the detachable IC token 2 was removed from the mobile communication terminal 1 can also be synchronized. It becomes like this.

  In S2 of FIG. 6, various specific methods of the synchronization process (S2) performed by the synchronization unit 10 of the mobile communication terminal 1 can be considered. For example, a method of deleting the usage history to which the unique number of the IC token 2 from which the usage history was read is added from the other IC token 2 and then writing the usage history to which the unique number of the IC token 2 is added to the other IC token 2 Can be considered.

  Also, if all the usage histories read from the IC token 2 are written to other IC tokens 2, the time required for the synchronization process (S2) becomes longer. Therefore, using the unique number of the IC token 2 from which the usage histories are read, the IC It is also possible to obtain the difference between the usage history read from the token 2 and the usage history already stored in the other IC token 2 and write only the difference into the other IC token 2.

  In the present embodiment, the synchronization means 10 of the mobile communication terminal 1 performs the synchronization process (S2), and then compares the usage history synchronized in the synchronization process (S2) between the IC tokens 2 to obtain the usage history. A consistency verification process for verifying consistency is executed (S3).

  The synchronization means 10 of the mobile communication terminal 1 displays the usage history and causes the user to select the correct usage history if there is a usage history in which inconsistency occurs in the consistency verification process, and the inconsistency occurs. A usage history correction process for unifying the usage history to the usage history selected by the user is performed (S4), and this procedure is terminated. Further, if there is no usage history in which inconsistency occurs in the consistency verification process, the synchronization unit 10 of the mobile communication terminal 1 ends this procedure without performing the usage history correction process.

  In the synchronization process (S2), the usage history stored in the other IC token 2 may be all the usage history stored in the IC token 2, but there is also a usage history that is not so necessary when a trouble occurs. In the mobile communication terminal 1 of the present embodiment, the synchronization means 10 of the mobile communication terminal 1 has a synchronization target specifying unit that allows a user to specify a usage history to be synchronized in advance, and the user synchronizes between IC tokens 2. The usage history to be selected can be selected.

  When the user selects a usage history to be synchronized between the IC tokens 2, the synchronization target designating unit of the synchronization unit 10 displays a list of applications installed in the mobile communication terminal 1 and uses the history between the IC tokens 2. The synchronization unit 10 synchronizes only the usage history corresponding to the application selected by the user between the IC tokens 2 in the synchronization process (S2).

  For example, when the secure memory card 2c is used for an electronic book, the synchronization means 10 of the mobile communication terminal 1 synchronizes the usage history between the IC tokens 2 because it is only necessary to know the electronic book purchased by the user at the time of trouble. When the application of the electronic book is not set as the application to be performed, the process of saving the usage history related to the use of the electronic book in the other IC token 2 is not executed in the synchronization process (S2).

  In the description so far, the information in the IC token 2 to be synchronized by the synchronization means 10 of the mobile communication terminal 1 is used history. However, information other than the usage history may be synchronized.

  Since the IC token 2 mounted on the mobile communication terminal 1 stores application information of an application that uses the IC token 2 in addition to the usage history, the application information may be synchronized between the IC cards.

  When synchronizing the application information, the synchronization means 10 of the mobile communication terminal 1 reads the application information stored in the IC token 2 and stores the read application information in another IC token 2 in the synchronization process (S2). Execute the process.

  For example, since the SIM card 2a stores an address book in which contacts of communication partners with whom contact is frequently made are stored, the synchronization means 10 uses the address book stored in the SIM card 2a as the SIM card. It is stored in the IC token 2 other than 2a (here, the short-range wireless communication device 2b and the secure memory card 2c).

  In addition, since the short-range wireless communication device 2b stores application information (for example, the balance of electronic money) of an application that uses the short-range wireless communication device 2b, the synchronization unit 10 is stored in the short-range wireless communication device 2b. The stored application information is stored in the IC token 2 (here, the SIM card 2a and the secure memory card 2c) other than the short-range wireless communication device 2b.

  Further, when the synchronization means 10 of the mobile communication terminal 1 performs the synchronization process (S2), the operation of the IC token 2 for reading the usage history is verified, and the verification result of the operation is obtained as information other than the usage history. It may be stored in the IC token 2.

  As described above, according to the mobile communication terminal 1 according to the present embodiment, when the synchronization trigger of the synchronization means 10 of the mobile communication terminal 1 is generated, for each IC token 2 mounted on the mobile communication terminal 1. The usage history of the IC token 2 is read out, and the read usage history is stored in another IC token 2 so that the usage history of the IC token 2 is backed up to another IC token 2 mounted on the same mobile communication terminal 1 It can be saved.

  Furthermore, by using at least the synchronization trigger that the detachable IC token 2 is mounted on the mobile communication terminal 1, it is possible to synchronize the usage history when the IC token 2 is removed.

  Furthermore, since the synchronization means 10 of the mobile communication terminal 1 includes the synchronization target designating unit, only the usage history designated by the user can be synchronized between the IC tokens 2.

  Furthermore, the synchronization means 10 of the mobile communication terminal 1 executes the consistency verification process (S3) and the usage history correction process (S4), so that there is a usage history in which inconsistencies occur between the IC tokens 2. However, it becomes possible to correct the usage history in which inconsistency occurs.

  Furthermore, in this embodiment, in addition to the usage history, the application information of the IC token 2 and the verification result of the operation of the IC token 2 can be synchronized between the IC tokens 2.
