Description

  The present invention relates to a technology of an apparatus and a method for determining an application identifier of a payment application to be deleted from payment applications installed in an IC chip.

  In recent years, mobile phones adopting NFC (Near Field Communication) technology have a card emulation function that behaves in the same way as a non-contact IC (Integrated Circuit) card, thereby using the mobile phone as an alternative to a non-contact IC card. Became possible. In a general system that uses a contactless IC card for payment, there is a single payment application installed on the contactless IC card. The owner of the contactless IC card is a payment operator and installs only the payment application of the company.

  However, when a mobile phone is used as an alternative to a contactless IC card, a SIM (Subscriber Identity Module) card (with an IC chip) on which a payment application is installed is the property of the carrier and installed there. Since the application to be installed is installed with the authority of the communication carrier, there is a possibility that the payment application of a plurality of payment operators may be simultaneously installed on the SIM card. Patent Document 1 discloses an IC card capable of managing data used in services of Company A and Company B, respectively.

  The IC card application compliant with the international standard ISO / IEC 7816-4 is not limited to the settlement application, but is identified by the identification information “application identifier” required when selected from the reader (reader / writer). The reading device transmits an application identifier together with the selection command, and the IC card that receives the selection interprets the selection command, searches for and selects an application that matches the application identifier. When payment applications of a plurality of payment operators are installed in the SIM card, the application identifier is configured to include, for example, an identifier registered by the payment operator and a value uniquely determined by the payment operator.

  At the time of settlement, the reader adds settlement brand registration information to the selection command and transmits it to the mobile phone. The SIM card mounted on the mobile phone searches for a payment application using the received payment brand registration information as a key, and responds with the success or failure of the search and, if successful, the application identifier of the found payment application. If the search is successful, the reading device adds the payment brand registration information to the selection command again and transmits it to the mobile phone. The SIM card performs a search for an application that is not yet a search target except for the application that is the target of the search, and if the search is successful, the application identifier of the payment application that is found when successful. respond. The reading device repeatedly executes this until the search fails, and acquires all application identifiers having the specified payment brand registration information among the payment applications installed in the SIM card, and displays the display unit of the reading device. To display. If there are a plurality of settlement means (settlement methods) in the SIM card, all of them are displayed on the display unit of the reading device, and one of them is selected for settlement.

The mobile terminal 1 is equipped with a SIM card 18 (small IC card) and a CLF (Contactless Front End) 19. The SIM card 18 is one of UICCs (Universal Integrated Circuit Cards). For example, the SIM card 18 is equipped with a contact IC chip whose function is expanded based on a conventional SIM (Subscriber Identity Module). The CLF 19 is a non-contact type IC chip that performs non-contact communication defined by the NFC standard, and is an antenna for transmitting and receiving various signals to and from a reading device (not shown) in the field of non-contact communication. It is connected to the. When the user places the portable terminal 1 over the reading device, a command (for example, indicating a payment request) transmitted from the reading device is transmitted to the SIM card 18 via an interface (not shown). Yes.

  FIG. 2 is a block diagram illustrating a schematic configuration example of the mobile terminal 1 according to the present embodiment. As shown in FIG. 2, the mobile terminal 1 includes a control unit 11, a storage unit 12, a wireless communication unit 13, a display unit 14, an input unit 15, an IC card connector 16a, an IC card protocol processing unit 16, and the like. These components are connected to each other via a bus 17.

  The control unit 11 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and controls the wireless communication unit 13, the display unit 14, the IC card protocol processing unit 16, and the like. To do. For example, an OS (Operating System) and middleware are stored in the ROM. Temporary work data is stored in the RAM.

  The storage unit 12 is configured by a nonvolatile memory such as a flash memory, for example. The storage unit 12 stores various applications (consisting of application program languages) and setting data, and an identifier determination program of the present invention. This application includes a UI application. The UI application is an application for installing a payment application on the SIM card 18, and is different for each payment operator, for example. The identifier determination program of the present invention may be incorporated as a function of the OS, middleware, or application. Then, the CPU (an example of the computer) of the control unit 11 executes the identifier determination program of the present invention, thereby functioning as a transmission unit, a reception unit, a determination unit, a determination unit, and the like in the present invention. Perform decision processing. From this application identifier determination process, the application identifier of the payment application to be deleted among the payment applications installed in the SIM card 18 can be specified. Even without using the TSM 3, an application identifier that does not overlap with the application identifier of the payment application already installed in the SIM card 18 can be assigned to the newly installed payment application.

  The wireless communication unit 13 includes an antenna and controls wireless communication performed with a base station in the mobile communication network. The display unit 14 includes, for example, a touch panel type display panel, and performs display control on the display panel and reception of instructions from the user.

Between the IC card protocol processing unit 16 and the SIM card 18, T = 0 protocol communication defined by the ISO / IEC7816 standard is performed. The T = 0 protocol communication is a half-duplex communication method, which recognizes communication data by changing the voltage level. When one of the two-party communication is transmission, the other is reception. The IC card connector 16a connects the CLF 19 and the C6 terminal of the SIM card 18. SWP (Single Wire Protocol) communication is performed between the CLF 19 and the SIM card 18. SWP communication is a full-duplex communication method that can simultaneously transmit in both directions.

  FIG. 3 is a block diagram illustrating a schematic configuration example of the IC chip C mounted on the SIM card 18 according to the present embodiment. As shown in FIG. 3, the IC chip C includes a CPU 181, a ROM 182, a nonvolatile memory 183, a RAM 184, an I / O circuit 185, and the like, and these components are connected to each other via a bus 186. The nonvolatile memory 183 is, for example, a flash memory, but may be an EEPROM (registered trademark). The ROM 182 or the nonvolatile memory 183 stores, for example, an OS and middleware. The non-volatile memory 183 stores a plurality of installed payment applications. The payment application is an IC applet for a SIM card, and is different for each payment company and each payment means. A unique application identifier is assigned to the settlement application stored in the nonvolatile memory 183 (the application identifier is also stored). Here, the application identifier includes, for example, payment brand registration information (information indicating a payment company). The payment brand registration information is an identifier (an example of first information) registered by the payment operator. In this embodiment, the application identifier is configured by concatenation of payment brand registration information, payment means (credit, debit, prepaid, etc.) information, and unique identification information. The settlement means information is a value (an example of second information) uniquely determined by the settlement operator.

  The I / O circuit 185 has eight connection terminals C1 to C8 defined by ISO / IEC7816 or the like. Here, the C1 terminal is a power supply terminal (VCC), and the C5 terminal is a ground terminal (GND). The C2 terminal is a reset terminal (RST), and the C3 terminal is a clock terminal (CLK). The C7 terminal is used for communication between the CPU 181 and the IC card protocol processing unit 16. The C6 terminal is used for communication between the CPU 181 and the CLF 19.

  When the CPU 181 receives a command from the CLF 19, the CPU 181 executes command processing (for example, settlement processing) according to the command, and sends (replies) a response indicating the result of the processing to the CLF 19. When the CPU 181 receives a command from the control unit 11, the CPU 181 executes command processing (for example, installation processing) according to the command, and sends a response indicating the result of the processing to the control unit 11.

  The UI application providing server 2 is a server that provides a UI application to the mobile terminal 1 via the network NW. The UI application providing server 2 stores a UI application for each settlement operator. The TSM 3 is a server that provides a payment application to the mobile terminal 1 via the network NW. The TSM 3 manages to which portable terminal 1 the payment application is provided (that is, installed in the SIM card 18). However, in the present embodiment, the TSM 3 does not need to manage the application identifier of the payment application provided to the mobile terminal 1, and payment brand registration information (information indicating a payment company) and payment means (credit, debit, prepaid) Etc.) Information and information unique to the portable terminal 1 (for example, a telephone number, a terminal ID, or a SIM number) may be stored and managed in association with each other.

  Next, an operation example until the payment application is installed in the SIM card 18 will be described. When installing a payment application on the SIM card 18, first, the control unit 11 of the mobile terminal 1 accesses the UI application providing server 2 according to an instruction from the user via the input unit 15, and requests a UI application. Thus, for example, a UI application of a desired settlement operator is downloaded from the UI application providing server 2 and installed. Next, when the control unit 11 of the mobile terminal 1 starts the installed UI application on the OS, the control unit 11 of the mobile terminal 1 accesses the TSM 3 according to the UI application, and sets the payment application specified by the user. By making a request, the settlement application is downloaded from the TSM 3 and installed in the SIM card 18. In other words, the UI application operating on the OS of the mobile terminal 1 transmits a request for installing the payment application to the SIM card 18 to the TSM 3, but before transmitting the request to the TSM 3, the control unit 11. Executes an application identifier generation process for generating an application identifier of the settlement application to be installed.

  FIG. 4 is a flowchart illustrating an example of an application identifier generation process in the control unit 11 of the mobile terminal 1. The process shown in FIG. 4 is started in response to an instruction from the user after the UI application is activated. In FIG. 4, the control unit 11 creates an application selection command to which payment brand registration information designated by the user is added, for example (step S1). At this time, since the control unit 11 has acquired the designated payment brand registration information and payment means information, the control unit 11 is configured to create an application selection command to which the payment brand registration information and payment means information are added. May be.

  Next, the control unit 11 transmits the created application selection command to the SIM card 18 via the IC card protocol processing unit 16 (step S2). When the CPU 181 of the SIM card 18 receives the application selection command, the CPU 181 executes processing according to the application selection command, whereby payment brand registration information (or payment brand registration information and payment means added to the application selection command) is executed. A payment application corresponding to the application identifier is searched for using the application identifier including “information” as a key. Thereby, when the payment application is found (that is, the payment application is stored in the nonvolatile memory 183), the CPU 181 of the SIM card 18 executes the execution result including the application identifier of the payment application ( The execution result of the application selection command is transmitted to the control unit 11. On the other hand, when the payment application is not found, the CPU 181 of the SIM card 18 transmits an execution result (execution result of the application selection command) indicating that there is no payment application to the control unit 11. Alternatively, when the settlement application is not found, the CPU 181 of the SIM card 18 may not transmit the execution result to the control unit 11. That is, the CPU 181 of the SIM card 18 may be configured to respond with an application identifier only when the search is successful.

  Next, when the control unit 11 receives (acquires) the execution result of the application selection command transmitted from the SIM card 18 (step S3), the control unit 11 determines whether the payment application is successfully selected (step S4). . When the application identifier is included in the execution result of the application selection command, it is determined that the payment application has been successfully selected (step S4: YES). In this case, the control unit 11 records the application identifier included in the execution result of the application selection instruction in the application identifier candidate list (step S5). Next, the control unit 11 changes the application selection command to next candidate designation (step S6), returns to step S2, and transmits the application selection command to the SIM card 18 via the IC card protocol processing unit 16. Note that the normal selection command selects the application that was found first, but by specifying the next candidate selection function, it is possible to exclude and search for applications that have already been searched.

  As described above, the control unit 11 transmits an application selection command to the SIM card 18, acquires the execution result of the application selection command from the SIM card 18, and includes an application identifier in the execution result. The process of recording the application identifier in the application identifier candidate list is repeatedly executed until it is not included in the execution result.

  If the application identifier is not included in the execution result of the application selection command (the response to the execution result of the application selection command may not be received), it is determined that the payment application is not successfully selected (step S4: NO). ), Go to step S7. In step S7, the control unit 11 sets unique identification information (unique identifier), which is a variable, to “0”. Subsequently, the control part 11 produces | generates the temporary application identifier comprised by payment brand registration information and payment means information, and the said unique identification information (step S8).

  Next, the control unit 11 determines whether or not the generated temporary application identifier is recorded in the application identifier candidate list (step S9). When it is determined that the temporary application identifier is recorded in the application identifier candidate list (step S9: YES), the control unit 11 adds “1” to the unique identification information (step S10), and returns to step S8. A new temporary application identifier is generated. That is, in this case, the control unit 11 generates a new temporary application identifier by changing the unique identification information included in the temporary application identifier. If the controller 11 determines that the generated temporary application identifier is not recorded in the application identifier candidate list (step S9: NO), the control application 11 uses the temporary application identifier to be installed in the SIM card 18. As the application identifier (step S11), and the process shown in FIG. 4 ends. In this way, an application identifier that does not overlap with the application identifier recorded in the application identifier candidate list is generated as the application identifier of the payment application installed in the SIM card 18.

  As described above, the control unit 11 generates a temporary application identifier, determines whether or not the temporary application identifier is recorded in the application identifier candidate list, and is recorded in the application identifier candidate list. If it is determined, the unique identification information included in the temporary application identifier is changed to generate a new temporary application identifier. Then, the control unit 11 performs a series of processes of determining whether or not the new temporary application identifier is recorded in the application identifier candidate list, and if the temporary application identifier is not recorded in the application identifier candidate list. The process is repeatedly executed until it is determined, and a temporary application identifier that is determined not to be recorded in the application identifier candidate list is generated as the application identifier of the settlement application installed in the SIM card 18. Thereby, the size of the unique identification information included in the application identifier can be optimized, and the load on the TSM 3 or the like that manages the payment application installed in the SIM card 18 can be reduced. By optimizing the size of the application identifier of the payment application in the credit payment service using the mobile terminal 1, the amount of data exchanged at the time of payment can be optimized, and the time required for the payment processing can be shortened. Become.

  Then, when the application identifier is generated by the application identifier generation process, the control unit 11 adds the generated application identifier to the request for installing the above-described settlement application in the SIM card 18 according to the UI application, Send the request to TSM3. When the TSM 3 receives the request from the mobile terminal 1, the TSM 3 creates an installation instruction using the application identifier added to the request and transmits the install instruction to the mobile terminal 1 (UI application). And the control part 11 of the portable terminal 1 will transmit this to the SIM card 18 according to UI application, if an installation command is received from TSM3. As a result, the CPU 181 of the SIM card 18 installs the payment application to which the application identifier generated by the application identifier generation process is assigned according to the received installation command.

  Next, an operation example until the payment application to be deleted is deleted from the payment applications installed in the SIM card 18 will be described. Deletion of the payment application may be performed by the user by his / her own intention, or may be performed by the payment operator regardless of the user's intention (for example, when the payment application is deleted from the portable terminal 1 of the user whose payment is delayed). . When the user deletes his / her own intention, the user activates the UI application and operates the GUI of the UI application to delete it. When the settlement operator implements regardless of the user's intention, it is periodically started from a UI application operating in the so-called background, which appears to be operating but not activated in the OS of the mobile terminal 1. In response, a delete command is transmitted as a response to the message transmitted to the TSM 3 and deleted. In this case, since the control unit 11 of the mobile terminal 1 identifies the payment application to be deleted, the control unit 11 of the mobile terminal 1 selects the deletion application from the payment applications installed on the SIM card 18. An application identifier determination process for determining the application identifier of the settlement application is executed.

  FIG. 5 is a flowchart illustrating an example of an application identifier determination process in the control unit 11 of the mobile terminal 1. The process shown in FIG. 5 is started in response to an instruction from the user after activation of the UI application or a deletion command from the TSM 3. In FIG. 5, the control unit 11 creates, for example, an application selection command in which payment brand registration information designated by a user or payment brand registration information added to a deletion command from the TSM 3 is added (step S21). Here, payment brand registration information is payment brand registration information corresponding to a payment application to be deleted. At this time, since the control unit 11 has acquired the designated payment brand registration information and payment means information, the control unit 11 is configured to create an application selection command to which the payment brand registration information and payment means information are added. May be.

  Next, the control unit 11 transmits the created application selection command to the SIM card 18 via the IC card protocol processing unit 16 (step S22). When the CPU 181 of the SIM card 18 receives the application selection command, the CPU 181 executes processing according to the application selection command, whereby payment brand registration information (or payment brand registration information and payment means added to the application selection command) is executed. A payment application corresponding to the application identifier is searched for using the application identifier including “information” as a key. Thereby, when the payment application is found (that is, the payment application is stored in the nonvolatile memory 183), the CPU 181 of the SIM card 18 executes the execution result including the application identifier of the payment application ( The execution result of the application selection command is transmitted to the control unit 11. On the other hand, when the payment application is not found, the CPU 181 of the SIM card 18 transmits an execution result (execution result of the application selection command) indicating that there is no payment application to the control unit 11. Alternatively, when the settlement application is not found, the CPU 181 of the SIM card 18 may not transmit the execution result to the control unit 11. That is, the CPU 181 of the SIM card 18 may be configured to respond with an application identifier only when the search is successful.

  Next, when the control unit 11 receives (acquires) the execution result of the application selection command transmitted from the SIM card 18 (step S23), the control unit 11 determines whether the payment application is successfully selected (step S24). . When the application identifier is not included in the execution result of the application selection command (the response of the execution result of the application selection command may not be received), it is determined that the selection of the settlement application is not successful (step S24: NO), The process shown in FIG. On the other hand, when the application identifier (that is, the application identifier including the payment brand registration information added to the application selection command) is included in the execution result of the application selection command, it is determined that the payment application has been successfully selected. (Step S24: YES). In this case, the control unit 11 includes, in the application identifier included in the execution result, payment means information corresponding to the payment application to be deleted (in other words, whether the payment means information matches the deletion target). It is determined whether or not (step S25). Based on the determination result, the control unit 11 determines the application identifier included in the execution result of the application selection command as the application identifier of the settlement application to be deleted. When the control unit 11 determines that the application identifier included in the execution result includes payment means information corresponding to the payment application to be deleted (step S25: YES), the BIN (Bank Identification Number) code is read. The BIN code is acquired by transmitting the command to the SIM card 18 (step S26), and the process proceeds to step S27. This BIN code is information included in the payment application identified by the application identifier included in the execution result. For example, the first six digits displayed on the credit card indicate the payment operator such as a card company. Information to identify. In order to determine that the application identifier is that of the payment application to be deleted, it is confirmed that the settlement means information included in the application identifier matches the deletion target, and the information ( BIN code, etc.) is read out and it is necessary to confirm that the issuer identified therefrom matches the deletion target.

  On the other hand, when the control unit 11 determines that the application identifier included in the execution result does not include the payment means information corresponding to the payment application to be deleted (step S25: NO), as in step S6. The application selection command is changed to the next candidate designation (step S28), the process returns to step S22, and the application selection command is transmitted to the SIM card 18 via the IC card protocol processing unit 16.

  In step S27, the control unit 11 determines whether or not the BIN code acquired in step S26 is information corresponding to the payment application to be deleted. When the acquired BIN code does not match the BIN code to be deleted, it is determined that the acquired BIN code is not information corresponding to the payment application to be deleted (step S27: NO), and the process proceeds to step S28. The selection command is changed to next candidate designation, and the process returns to step S22. On the other hand, when the acquired BIN code matches the BIN code to be deleted, it is determined that the acquired BIN code is information corresponding to the payment application to be deleted (step S27: YES). The unit 11 determines the application identifier included in the execution result of the application selection command as the application identifier of the payment application to be deleted (step S29), and ends the process shown in FIG. As described above, when the application identifier to be deleted can be identified, the control unit 11 of the mobile terminal 1 transmits the application identifier to the TSM 3. When the TSM 3 receives the application identifier, it creates a delete instruction and returns it to the UI application. Thereby, the UI application transmits the received deletion command to the SIM card 18, and the SIM card 18 that has received the deletion command deletes the corresponding payment application.

  In the first place, there may be a case where the above-described settlement means information does not exist. In step S24 in this case, when the application identifier is included in the execution result of the application selection command, that is, when it is determined that the payment application has been successfully selected (step S24: YES), the control unit 11 Shifts to step S29, and is configured to determine the application identifier included in the execution result of the application selection instruction as the application identifier of the settlement application to be deleted.

  As described above, according to the above-described embodiment, the mobile terminal 1 transmits the application selection command to which the payment brand registration information corresponding to the payment application to be deleted is added to the SIM card 18 to select the application. The execution result of the command is received from the SIM card 18. When the application identifier including the payment brand registration information added to the application selection command is included in the execution result of the application selection command, the mobile terminal 1 sets the payment to be deleted in the application identifier included in the execution result. It is determined whether or not payment means information corresponding to the application for application is included, and based on the determination result, the application identifier included in the execution result of the application selection instruction is determined as the application identifier of the payment application to be deleted Therefore, the UI application does not have the function of storing the application identifier, or the UI application is deleted for some reason, and a new UI application is deleted for the purpose of deleting the payment application. Application of the payment application to be deleted even if the application is installed or the SIM card in which the payment application to be deleted is installed is pulled out from the mobile terminal and inserted into another mobile terminal An identifier can be specified.

  In the above embodiment, the application identifier determined by the application identifier determination process shown in FIG. 3 is assigned by, for example, a settlement operator other than the application identifier generated by the application identifier generation process shown in FIG. This can also be applied to the application identifier stored in FIG.

  In the above embodiment, an example in which the present invention is applied to installation of a payment application has been described. However, the present invention can also be applied to applications other than the payment application.
