  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a configuration example of a communication system to which the present invention is applied.

  The communication system shown in FIG. 1 includes a server computer 1, a client computer 2 connected to the server computer 1 via a network, and a user that is in close proximity to the client computer 2 at a predetermined timing. The card 3 is used for communication with the client computer 2. The server computer 1 executes a server application 11 and the client computer 2 executes a client application 31.

  In the communication system of FIG. 1, for example, communication is performed between the server application 11 and the client application 31, and is built in the client computer 2 by the business logic 21 of the server application 11 executed by the server computer 1. The operation of the IC chip 41 is controlled.

  In FIG. 1, the IC chip 41 is illustrated inside the client application 31, but this is because a command from the server application 11 (business logic 21) is supplied to the IC chip 41 via the client application 31. It represents that.

  The IC chip 41 includes an IC card function unit 51 that realizes an IC card function and an R / W function unit 52 that realizes a reader / writer function (R / W function). The IC chip 41 may be composed of a single-chip physical module, or may be composed of a plurality of physical modules that realize each of the IC card function and the R / W function. Good.

  Here, the IC card function executes a command transmitted from the server computer 1 or a command transmitted from an external device such as an external reader / writer (not shown) close to the client computer 2, According to the command, it refers to a function of storing predetermined data or providing the stored data to an external device that has transmitted the command. For example, according to a command transmitted from an external device, electronic money information of a predetermined amount, information on commuter passes for using various transportation facilities, and the like are stored by the IC card function. One that provides an IC card function is, for example, FeliCa (registered trademark).

  The R / W function is transmitted from the server computer 1 or the like to the card 3 having an IC card function outside the client computer 2 using, for example, wireless communication using electromagnetic induction. This is a function that reads and writes (reads and writes) data stored in the IC card function of the card 3 by supplying the incoming command and causing the external IC card function to execute the command.

  Based on the notification from the server computer 1 (business logic 21), the client application 31 that controls the IC chip 41 composed of the IC card function unit 51 and the R / W function unit 52 that realize each of these functions is provided. The command transmitted from the server computer 1 is identified as to which of the IC card function unit 51 and the R / W function unit 52 is concerned, and the IC card function unit 51 or the R / W function unit 52 is identified. To control.

  For example, the client application 31 sends a command to the IC card function unit 51 for a command transmitted after being notified that the command is related to the operation of the IC card function unit 51 (command related to the internal IC card function). For commands sent after being notified that the command is related to the operation of the R / W function unit 52 (command related to the external IC card function), the R / W function unit 52 is controlled, The command is supplied to the card 3 and is executed by the IC card function unit 61. As will be described later, information for notifying the control target may be transmitted from the business logic 21 together with a command.

  Thus, since the server computer 1 notifies whether the transmitted command relates to the internal IC card function or the external IC card function, the client computer 2 is connected to the server computer. The command can be supplied to the supply destination assumed by 1.

  On the other hand, the server computer 1 selects and controls either the internal IC card function or the external IC card function because the client computer 2 switches the command destination based on the notification from the server computer 1. be able to.

  When the server computer 1 cannot select the control target, for example, when the client computer 2 and the card 3 are close to each other (from the server computer 1 both the internal IC card function and the external IC card function are In a controllable state), the client computer 2 cannot identify to which function the command transmitted from the server computer 1 is a command.

  Returning to the description of FIG. 1, the card 3 has a card-like appearance, and an IC card that realizes the same IC card function as that realized by the IC card function unit 51 of the client computer 2 at a predetermined position. The function unit 61 (chip having the IC card function unit 61) is embedded.

  The IC card function unit 61 performs short-distance wireless communication with the R / W function unit 52 when the card 3 is close to the client computer 2, and commands supplied from the R / W function unit 52. Execute. When the command is executed by the IC card function unit 61, for example, rewriting of electronic money information stored in the IC card function of the card 3 is performed.

  The operation of the communication system including such devices will be described later with reference to flowcharts.

  FIG. 2 is a block diagram illustrating a functional configuration example realized by the business logic 21 of the server computer 1.

  The communication control unit 81 controls communication performed with the client application 31 of the client computer 2. For example, the communication control unit 81 transmits a command for the IC chip 41 supplied from the device control unit 82 to the client application 31 and represents a function targeted by the command to be transmitted supplied from the function selection unit 83. Send information.

  The communication control unit 81 also includes information representing the processing result returned from the client computer 2 when a command is executed in the IC card function unit 51 of the client computer 2 or the IC card function unit 61 of the card 3. Is output to the device control unit 82 or the function selection unit 83.

  The command transmitted to the client computer 2 may be generated by another tamper-resistant device connected to the server computer 1 in accordance with an instruction from the server application 11.

  The function selection unit 83 selects a function to be controlled by a command from an internal IC card function of the client computer 2 and an external IC card function (IC card function of the card 3), and displays the selection result as a communication control unit. The client computer 2 is notified via 81. The selection result by the function selection unit 83 is also notified to the device control unit 82.

  FIG. 3 is a block diagram illustrating a functional configuration example realized by the client application 31 of the client computer 2.

  The communication control unit 91 controls communication performed with the server application 11 (business logic 21) of the server computer 1. For example, the communication control unit 91 outputs a command transmitted from the business logic 21 and a notification of a function to be controlled to the function switching unit 92. In addition, the communication control unit 91 transmits information representing the processing result of the command supplied from the IC card function control unit 93 or the R / W function control unit 94 via the function switching unit 92 to the business logic 21.

  The function switching unit 92 switches the command supply destination based on the notification from the business logic 21. For example, the function switching unit 92 uses the IC card function control unit 93 as the destination of the command transmitted after being notified that the command is related to the internal IC card function, and is a command related to the external IC card function. The R / W function control unit 94 is a supply destination of the command transmitted after the notification is received.

  The IC card function control unit 93 causes the IC card function unit 51 of the IC chip 41 to execute the command supplied from the function switching unit 92 and update the data. In addition, the IC card function control unit 93 outputs information representing the command processing result to the communication control unit 91 via the function switching unit 92.

  The R / W function control unit 94 transmits the command supplied from the function switching unit 92 to the IC card function unit 61 of the card 3 by controlling the R / W function unit 52 of the IC chip 41 to be executed. . Further, the R / W function control unit 94 outputs information representing the processing result of the command by the IC card function unit 61 to the communication control unit 91 via the function switching unit 92.

  Next, the operation of each device having the above configuration will be described with reference to flowcharts.

  First, a series of processes in which control is performed for the IC card function unit 51 built in the client computer 2 will be described with reference to the flowchart of FIG.

  For example, when access from the client application 31 is received and charging (addition) of electronic money information of a predetermined amount is requested, the function selection unit 83 of the server application 11 (business logic 21) The internal IC card function is selected, and the selection result is notified to the client application 31 in step S1.

  In the client application 31, all of the commands transmitted after this notification are handled as targets for the internal IC card function.

  The notification from the function selection unit 83 is received by the function switching unit 92 via the communication control unit 91 in step S11. In step S12, the function switching unit 92 makes a response such as notifying the server application 11 that the notification has been received.

  In step S <b> 2, the function selection unit 83 of the server application 11 receives the response from the client application 31 and notifies the device control unit 82 that there is a response from the client application 31.

  In step S <b> 3, the device control unit 82 generates a command for adding the electronic money information stored in the IC card function unit 51 for the requested amount, and sends the generated command to the communication control unit 81. To the client application 31.

  In step S13, the function switching unit 92 of the client application 31 receives the command transmitted from the server application 11, proceeds to step S14, and based on the notification received in step S11, the transmitted command Recognize that the IC card function is to be executed. The command transmitted from the server application 11 is output from the function switching unit 92 to the IC card function control unit 93.

  In step S <b> 15, the IC card function control unit 93 supplies the command transmitted from the server application 11 to the IC card function unit 51.

  In step S31, the IC card function unit 51 executes the command supplied from the IC card function control unit 93, proceeds to step S32, and returns the processing result. Here, for example, information notifying that the addition of electronic money information has been completed normally is returned as a response.

  The IC card function control unit 93 of the client application 31 receives the processing result of the command returned as a response from the IC card function unit 51 in step S16, proceeds to step S17, and passes it through the function switching unit 92. Then, it is transmitted from the communication control unit 91 to the server application 11.

  In step S4, the device control unit 82 of the server application 11 receives a response from the client application 31, proceeds to step S5, and sends a command for the internal IC card function following the command transmitted in step S3 to the client. Send to application 31. Thereafter, the command transmission is repeated a predetermined number of times.

  In step S18, the function switching unit 92 of the client application 31 receives the command transmitted from the server application 11, recognizes that the command is also to be executed by the internal IC card function, and similarly. Then, the IC card function unit 51 is caused to execute a command.

  That is, it is repeatedly transmitted from the server application 11 a predetermined number of times until there is a next function notification (whether the function to be controlled is an internal IC card function or an external IC card function). The incoming command is output to the IC card function control unit 93 and executed by the IC card function unit 51.

  Next, a series of processes in which control is performed for the IC card function unit 61 built in the card 3 will be described with reference to the flowchart of FIG.

  For example, when charging of a predetermined amount of electronic money information is requested from the client application 31, the function selection unit 83 of the server application 11 selects a target function as an external IC card function, and in step S41, The client application 31 is notified of the selection result.

  In the client application 31, all of the commands transmitted after this notification are handled as targets for the external IC card function, unlike those described with reference to FIG.

  The notification from the function selection unit 83 is received by the function switching unit 92 of the client application 31 in step S61. The function switching unit 92 makes a response to the server application 11 in step S62.

  For example, the function switching unit 92 determines whether or not the IC card function unit 61 is in proximity based on the output from the R / W function control unit 94 and responds by notifying the determination result. Note that, when the short-distance wireless communication with the IC card function unit 61 is not possible, the function switching unit 92 notifies the server application 11 of the fact. In this case, the control is terminated because control for the external IC card function is impossible.

  In step S42, the function selection unit 83 of the server application 11 receives the response from the client application 31, and notifies the device control unit 82 that there has been a response from the client application 31.

  In step S <b> 43, the device control unit 82 generates a command for adding the electronic money information stored in the IC card function unit 61 by the requested amount, and transmits the generated command to the client application 31.

  In step S63, the function switching unit 92 of the client application 31 receives the command transmitted from the server application 11, proceeds to step S64, and based on the notification received in step S61, the transmitted command That the IC card function is executed, that is, the IC card function unit 61 is transmitted using the R / W function unit 52. The command transmitted from the server application 11 is output from the function switching unit 92 to the R / W function control unit 94.

  In step S65, the R / W function control unit 94 supplies the command transmitted from the server application 11 to the R / W function unit 52 and causes the IC card function unit 61 to transmit the command.

  In step S81, the R / W function unit 52 receives the command supplied from the R / W function control unit 94, proceeds to step S82, and sends the command via short-range wireless communication using electromagnetic induction. The data is transmitted to the IC card function unit 61.

  At this time, for example, on the display unit (not shown) of the client computer 2, a message prohibiting the movement of the card 3 from the range where the radio wave from the R / W function unit 52 reaches is displayed. The

  In step S91, the IC card function unit 61 of the card 3 receives and executes the command transmitted from the R / W function unit 52. Further, the IC card function unit 61 proceeds to step S92 and returns the processing result to the R / W function unit 52.

  The reply from the IC card function unit 61 of the card 3 is received by the R / W function unit 52 in step S83, proceeds to step S84, and is supplied to the R / W function control unit 94.

  The R / W function control unit 94 of the client application 31 receives the processing result of the command returned as a response from the IC card function unit 61 in step S66, proceeds to step S67, and sends it to the communication control unit 91. The server application 11 is transmitted.

  In step S44, the device control unit 82 of the server application 11 receives a response from the client application 31, proceeds to step S45, and sends a command for the external IC card function following the command transmitted in step S43 to the client. Send to application 31. Thereafter, the command transmission is repeated a predetermined number of times.

  In step S68, the function switching unit 92 of the client application 31 receives the command transmitted from the server application 11, recognizes that the command is also a command to be executed by the external IC card function, and performs similar processing. I do.

  That is, the function switching unit 92 repeatedly outputs a command transmitted from the server application 11 to the R / W function control unit 94 a predetermined number of times until the next function is notified, and sends the command to the IC card function unit 61. To run.

  As described above, since the command is transmitted from the server computer 1 after the notification of whether the function to be controlled is internal or external, the client computer 2 It is possible to reliably identify which function the command transmitted from the server computer 1 is intended for. That is, it is possible to prevent functions that are not intended by the server computer 1 (the creator of the business logic 21) from being controlled.

  Further, since the function on the client computer 2 side can be identified, the server computer 1 reads out the electronic money information stored in the IC card function unit 51, for example, and uses the read electronic money information as an external IC. It is possible to perform control that requires switching of the control target, such as moving to the card function unit 61 (value transfer).

  In the above description, before a command is transmitted, it is assumed that a command to be transmitted thereafter is notified of which function is targeted. Notification of a function to be performed may be performed from the server computer 1 to the client computer 2. That is, in this case, every time a command is transmitted, notification of the target function is performed.

  Next, referring to the flowchart of FIG. 6, every time a command is transmitted, notification of the IC card function to be controlled is performed, and control for the IC card function unit 51 built in the client computer 2 is performed. A series of processes will be described.

  This process is the same as the process described with reference to FIG. 4 except that notification of the target function is performed before each command is transmitted, instead of being notified for each command transmission. It is.

  That is, for example, when charging of electronic money information is requested from the client application 31, the function selection unit 83 of the server application 11 selects a target function as an internal IC card function and performs communication control on the selection result. To the unit 81. This selection result is also notified from the function selection unit 83 to the device control unit 82. On the other hand, the device control unit 82 generates a command for adding the electronic money information stored by the IC card function by the requested amount, and outputs the generated command to the communication control unit 81.

  In step S <b> 101, the communication control unit 81 transmits the command generated by the device control unit 82 to the client application 31 together with the information for notifying the function targeted for the command supplied from the function selection unit 83.

  Information (information and command for notifying functions) transmitted from the server application 11 is received by the function switching unit 92 of the client application 31 in step S111.

  In step S112, the function switching unit 92 recognizes that the command transmitted together with the notification is a command to be executed by the internal IC card function based on the notification from the server application 11. The command transmitted from the server application 11 is output from the function switching unit 92 to the IC card function control unit 93.

  In step S113, the IC card function control unit 93 supplies the command transmitted from the server application 11 to the IC card function unit 51 to be executed.

  In step S121, the IC card function unit 51 executes the command supplied from the IC card function control unit 93, proceeds to step S122, and returns the processing result.

  In step S114, the IC card function control unit 93 of the client application 31 receives the processing result of the command returned as a response from the IC card function unit 51, proceeds to step S115, and passes it through the function switching unit 92. Then, it is transmitted from the communication control unit 91 to the server application 11.

  The device control unit 82 of the server application 11 receives the response from the client application 31 in step S102.

  Thereafter, in the same manner, when the IC card function unit 51 of the client computer 2 executes a command, information that notifies the command and the command generated by the device control unit 82 are collectively collected in step S103. 81. Similarly, when the command is to be executed by the external IC card function unit 61, the notification information and the command generated by the device control unit 82 are collectively transmitted from the communication control unit 81.

  In step S116, the function switching unit 92 of the client application 31 receives the information transmitted from the server application 11, and sends the transmitted command to the IC card function based on the notification (internal) of the function to be controlled. This is supplied to the controller 93.

  Next, referring to the flowchart of FIG. 7, every time a command is transmitted, notification of the IC card function to be controlled is performed, and control for the IC card function unit 61 built in the card 3 is performed. A series of processing will be described.

  This process is also the same as the process described with reference to FIG. 5 except that the notification of the target function is performed every time a command is transmitted instead of the notification of the target function before the command is transmitted. It is.

  That is, for example, when the client application 31 requests charging of electronic money information, the function selection unit 83 of the server application 11 selects a target function as an external IC card function, and performs communication control on the selection result. To the unit 81. On the other hand, the device control unit 82 generates a command for adding the electronic money information stored by the IC card function by the requested amount, and outputs the generated command to the communication control unit 81.
