Description

  The present invention relates to a mobile terminal such as a mobile phone terminal, and more particularly to a mobile terminal with a built-in or attached short-range wireless communication function called a non-contact type IC card.

  In recent years, the use of non-contact type IC cards is rapidly spreading as transportation tickets, membership cards, employee cards, cards for payment methods at stores, and the like. The non-contact type IC card performs authentication processing by performing wireless communication with a nearby reader / writer, and thus can be used in a wallet or the like, and is more convenient than a magnetic card or the like.

  On the other hand, such a non-contact type IC card (or a circuit component having the same function as the IC card) is built in a portable electronic device such as a mobile phone terminal, and these devices are used in the same manner. Proposals have been made to enable authentication and settlement. When it is configured to incorporate an IC card in a mobile terminal such as a mobile phone terminal, a case where a functional unit as an IC card is incorporated in a state where it cannot be taken out from the mobile terminal, and a card slot prepared in the mobile terminal, Although it is assumed that an IC card is mounted, it can be used in any case in a state where it is attached to a portable terminal. When the IC card function unit is incorporated into the mobile terminal, the IC card function unit is not necessarily in the shape of a card. However, in the following description, the IC card function unit is particularly described when referred to as an IC card. Unless otherwise specified, it includes a portion having an IC card function.

  When wireless communication is performed with a reader / writer in proximity using the IC card function unit, not only the identification number data given to the IC card is sent to the reader / writer, but also the name and In some cases, personal information such as an address is also sent for authentication processing. It is possible to store not only phone numbers but also names, addresses, genders, dates of birth, e-mail addresses, etc. in advance in mobile phone terminals. It is possible to perform various authentication processes or perform various services associated with the authentication.

Japanese Patent Application Laid-Open No. 2004-133620 discloses that an IC card is built in a mobile phone terminal. Japanese Patent Application Laid-Open No. 2004-228561 discloses that personal information stored in a communication device is sent to the outside via a network.

  By the way, in the case of a card-shaped IC card, it is common for a single card to function as one type of ticket or membership card prepared by a distributor that distributes the card. In the case of an integrated IC card, a plurality of card functions can be set in an IC card built in one mobile phone terminal.

  For example, an IC card function that can be used as a transit ticket (commuter pass) is set in an IC card built in one mobile phone terminal, and an IC card function that can be used as a membership card is set. It can be used.

  Here, when a mobile phone terminal with an IC card function is brought close to a reader / writer, the information sent from the IC card function unit to the reader / writer differs depending on which system the reader / writer is connected to. Since the user who has the mobile phone terminal cannot know directly what kind of information is sent when communicating with the reader / writer, he / she has anxiety about the leakage of personal information. In particular, as described above, since various personal information can be stored in the mobile phone terminal, there is anxiety that such stored personal information may be leaked through communication with the reader / writer. End up.

  If there is such anxiety, the user who possesses the mobile phone terminal with the IC card function will hesitate to use the IC card function, and as a result, it becomes a factor that hinders the spread of the IC card function. . In the above description, the case where the IC card function is incorporated in the mobile phone terminal has been described. However, the case where the IC card function is incorporated in a portable terminal such as a data terminal such as a PDA (Personal Digital Assistance) is also described. Have a similar problem.

  The present invention has been made in view of this point, and an object of the present invention is to make it possible to satisfactorily control the use of personal information when using a non-contact IC card function built in a portable terminal.

  The present invention provides a portable terminal equipped with a short-range wireless communication means for performing short-range wireless communication with a reader / writer connected to a predetermined system so that the reader / writer recognizes at least personal information. Control the short-distance wireless communication in the storage means and the short-range wireless communication means, and store any personal information in the short-distance wireless communication means in the short-distance wireless communication means. And control means for setting whether to transmit for each system.

  By doing so, the usage status of the personal information stored in the portable terminal during communication with the reader / writer can be set for each system.

  According to the present invention, the usage status of personal information stored in a portable terminal during communication with a reader / writer can be set on the terminal side for each system, and the user who owns the terminal operates the authentication system. You can select information that can be disclosed to the user, and personal information that the user who owns the terminal will not be sent at the time of authentication will not be sent without the user's awareness, and there is a sense of security when using the IC card function Will lead to the use of IC card functions.

  In this case, it is possible to confirm the setting of the personal information used when communicating with the reader / writer from the display by providing display means for displaying the setting of the usage state of the personal information.

  In addition, since the operating means for changing the setting displayed on the display means is provided, the setting can be easily changed by operating the operating means.

  In addition, the personal information set by the control means is sent from the short-range wireless communication means to the reader / writer for authentication, and when there is personal information that is insufficient for the authentication, a notification means for notifying the fact is provided. As a result, it becomes clear at the time of authentication that there is a shortage of personal information set to be used during communication.

  Furthermore, when it is determined at the time of authentication that the set personal information is insufficient, the personal information that is insufficient in a predetermined operation is transmitted from the short-range wireless communication means to the reader / writer. Can be completed correctly.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
In this example, the present invention is applied to a mobile phone terminal having a built-in IC card function for wireless communication without contact.

  FIG. 1 is a diagram showing a configuration example of the mobile phone terminal of this example. First, the transmission configuration as a wireless telephone terminal will be described. Data that is supplied to the microphone 11 as a digital signal by supplying the voice signal input to the microphone 11 and supplied to the digital signal processing unit 13 as a packet for transmission Processing is performed, and the obtained transmission packet is supplied to an RF (high frequency) input / output unit 14, modulated for transmission, converted to a predetermined transmission frequency, and wirelessly transmitted from the connected antenna 15.

  As a reception configuration as a radiotelephone terminal, a signal in a predetermined frequency band received by the antenna 15 is subjected to reception processing by an RF (high frequency) input / output unit 14 and subjected to demodulation processing for reception to obtain a reception packet. The obtained received packet is supplied to the digital signal processing unit 13 to extract each data in the packet such as an audio signal. The extracted audio signal is supplied to the audio output unit 16, performs output processing such as analog conversion and amplification, and is output from the connected speaker 17.

  These transmission and reception processes are configured to be executed based on the control of the control unit 21 as control means for controlling the telephone function of the wireless telephone terminal. When the operation unit 24 composed of various operation means such as operation keys arranged in the wireless telephone terminal is operated, a command based on the operation is supplied to the control unit 21 and the control unit 21 is instructed. To control.

  In addition, the wireless telephone terminal of this example is provided with a display unit 22 as a display unit for displaying information such as a telephone number, a mail text, a web screen, a communication status, and the display unit is smaller than the display unit 22. In some cases, the sub display unit 23 may be provided. The display on the display unit 22 and the sub display unit 23 is executed under the control of the control unit 21. Further, data transfer with the outside via the external interface unit 25 provided in the mobile phone terminal is also executed under the control of the control unit 21.

  The control unit 21 is connected to a memory 26 composed of a non-volatile storage unit or the like, and various kinds of information necessary as a wireless telephone terminal are registered in the memory 26. As information registered (stored) in the memory 26, for example, there is personal information such as the telephone number of the terminal, the name, address, gender, date of birth, and mail address of the terminal owner. Also, in this example, when performing an authentication process using an IC card function unit, which will be described later, the setting of which personal information is used is stored in the memory 26 for each type of authentication. Details of the setting for using the personal information will be described later.

  In addition, the control unit 21 is configured to perform various notifications to the user who owns the terminal by controlling the display state on the display unit 22 and the sub display unit 23 and the output state of the warning sound from the speaker 17. .

  The mobile phone terminal of this example incorporates an IC card function unit 31. The IC card function unit 31 has a built-in memory, and a code for identifying and authenticating the user, a charged amount, data registered as a boarding ticket and various tickets, and the like are stored in the memory. An IC card antenna 32 is connected to the IC card function unit 31. The IC card antenna 32 receives radio waves transmitted from an external reader / writer at a predetermined frequency, and is close to the reader / writer. If it is determined that the state has been established, bidirectional wireless communication is performed with the reader / writer. The wireless communication between the IC card antenna 32 and the reader / writer is wireless communication between very close distances such as a distance of about several centimeters.

  When communication is performed between the IC card function unit 31 and the reader / writer, for example, data such as an identification code stored in the IC card function unit 31, an amount, and registered conditions are stored on the reader / writer side. And let the reader / writer recognize it. If necessary, data to be written to the memory is sent from the reader / writer side, and the data stored in the IC card function unit 31 is updated.

  The operation of the IC card function unit 31 may be configured to operate with the electric power received from the reader / writer side and stored in a capacitor or the like, but the power is supplied from the power supply unit in the terminal. You may make it operate | move.

  When the IC card function unit 31 performs wireless communication with a reader / writer and performs processing such as authentication, the basic authentication processing is completed within the IC card function unit 31. The control unit 21 shares and executes some functions. Specifically, for example, when a part of the personal information stored in the memory 26 is wirelessly transmitted to the reader / writer at the time of authentication, the personal information set to be transmitted by the authentication at that time is transmitted to the control unit 21. Is read from the memory 26 and sent to the IC card function unit 31 for transmission to the reader / writer. The personal information set to be sent at the time of authentication is stored in the memory in the IC card function unit 31, and the IC card function control means in the IC card function unit 31 controls reading. You may do it. Or conversely, all the information necessary for authentication may be stored in the memory 26 side, and the control unit in the IC card function unit 31 may read out each necessary data via the control unit 21.

  Next, setting processing of personal information transmitted when performing wireless communication with an external reader / writer connected to some kind of authentication system using the IC card function unit 31 of the mobile phone terminal of this example is performed. This will be described with reference to FIG.

  As described above, when wireless communication is performed with an external reader / writer, not only authentication data such as an authentication code but also various personal information may be sent. In addition to the personal information that must be sent at the time of authentication, the personal information is not necessarily required, but is received when sent to the reader / writer and used by the company operating the system. There is also.

  In this example, the IC card function that can be registered in the IC card function unit 31 can be authenticated by a plurality of IC card systems. In the following description, a program registered in the IC card function unit 31 in the terminal for authentication with one IC card system is referred to as one application.

  For each application, which personal information is wirelessly transmitted from the IC card antenna 32 is set in advance, and the control unit 21 registers the information in the memory 26. As for the registration process, for example, the one selected by the user operation of the operation unit 24 is registered based on the display on the display unit 22.

  FIG. 2 is a diagram showing an example of personal information set to be transmitted for each application. Here, for example, the application 1 performs authentication for a system for settlement as electronic money, and the application 1 is set not to send any personal information.

  The application 2 is used as a regular ticket for transportation. In the application 2, personal information 1, 2, 3, 4, 6 (for example, name, address, date of birth, telephone number, gender) ).

  The application 3 is used as a membership card of a specific store. In the application 3, personal information 1, 2, 3, 4, 5 (for example, name, address, date of birth, telephone number, mail) Address).

  The application 4 is used by communicating with a reader / writer connected to a personal computer device possessed by the user. In the application 4, personal information 8, 9 (for example, telephone book data, schedule information) Data).

  In this way, there is a setting for sending personal information for each application. For example, as the application N, personal information 6 and 7 (for example, sex data and age data) are sent.

  In this way, since personal information is set for each application, personal information transmitted for each application can be set.

  In the example of FIG. 2, the setting is made for each application registered in the IC card function unit 31, but the correspondence between the application and personal information may be set for each application level. That is, for example, as shown in FIG. 3, personal information to be transmitted may be determined for each level, and the level of each application may be set.

  Alternatively, as shown in FIG. 4, personal information to be transmitted may be determined for each category, and the category of each application may be determined.

  Since personal information to be transmitted at the time of authentication can be set in this way, if only data that can be transmitted to the user is set, only personal information that can be transmitted to the other party for the user is transmitted.

  Personal information to be transmitted can be set in this way, but there is insufficient data on the system side when the system side connected to the reader / writer is necessary for authentication when communicating with the reader / writer May be notified to the terminal side, and it may be selected whether or not to send the shortage of personal information on the terminal side.

  The flowchart of FIG. 5 shows an example of processing in that case. Hereinafter, the processing example will be described. First, communication for authentication is performed on the reader / writer side, and it is determined whether or not necessary personal information is obtained in the system (step S11). Here, when necessary personal information is obtained, the authentication process is terminated. If the necessary personal information cannot be obtained, the reader / writer requests the terminal for the necessary personal information (step S12). In the terminal that has received the request, the display unit 22 or the sub display unit 23 displays that there is a request for transmitting personal information (step S21). When the requested personal information is transmitted from the terminal with this display, the user operates an operation key or the like. The control unit determines whether or not there is this operation (step S22). If there is no operation, the control unit stops the authentication process and fails here (step S23).

  Then, when there is an operation for transmitting the requested personal information, the requested personal information that is insufficient is wirelessly transmitted to the reader / writer (step S24).

  When the reader / writer receives insufficient personal information (step S13), the reader / writer completes the authentication process here and notifies the terminal of the completion of authentication (step S14). The terminal that has received the notification confirms that the authentication has been completed (step S25). The completion of the authentication may be notified by sound or display. In addition, when such insufficient personal information is sent, when performing communication for authentication with the reader / writer of the same application thereafter, the user's display confirms whether or not the insufficient personal information is also transmitted at the same time. Then, when there is an operation to be approved by the confirmation, registration may be made so that the personal information that is lacking is also transmitted.

  In this way, since the personal information to be transmitted at the time of authentication can be selected, the user can know which personal information is sent for each application to be used, and the user can use the IC card function with peace of mind. If the selected personal information lacks authentication data, a process for requesting the data is performed, so that it can be easily dealt with.

  In the above-described embodiment, an example is described in which the IC card function is incorporated in the mobile phone terminal. However, the same processing can be applied when the IC card function is incorporated in various other portable terminal devices. Is possible. The IC card function built into the terminal is prepared in the terminal in addition to the case where a circuit block for realizing the same function as the IC card is built in the terminal (in the case of the above-described embodiment). As a configuration in which an IC card is mounted in a card slot or the like, a position where the mounted IC card can communicate may be displayed.
