FIG. 3 is a system block diagram of an IC card use area limiting system according to an embodiment of the present invention, and FIG. 4 is an IC card use area limiting system according to an embodiment of the present invention. The functional block diagram of the CPU of the IC card used, FIG. 5 is a flowchart showing the processing procedure of the IC card use area limiting system according to the embodiment of the present invention.

  As shown in FIG. 1, the IC card use area limiting system according to the embodiment of the present invention receives a GPS signal transmitted from a GPS communication satellite 1, and based on the received GPS signal. A mobile phone 2 that is a mobile terminal having a function of calculating and detecting position information based on latitude and longitude and an IC card 3 that is detachably attached to the mobile phone 2 are used.

  Various sizes of the IC card 3 are used according to the mobile phone 2, and a small size IC card such as a UIM card is also included.

  The mobile phone 2 is provided with an IC card mounting portion for detachably mounting the IC card 3, and a plurality of users can be shared by replacing the IC card 3 owned by each individual user. Can be used.

  The cellular phone 2 is equipped with an IC card 3 owned by the user and uses information stored in the storage means of the IC card 3 to provide various information via the Internet, It is possible to receive service information such as point services and prepaid services that can be used when conducting business transactions and purchasing products at stores.

  In addition, in the EEPROM which is the storage means of the IC card 3, usage area information for limiting the area where the IC card 3 can be used is registered in advance, and the mobile phone 2 to which the IC card 3 is attached. Thus, when using the information stored in the IC card 3, the use area is restricted so that it cannot be used outside the area specified by the use area information.

  This usage area information can determine different areas for each user, and by specifying the area corresponding to each user and registering it in the IC card 3, the issuer side of IC card 3 and service provision The user can select and set usage restrictions according to the IC card user.

  Next, based on FIG. 2, the outline | summary of the utilization area limitation system of the IC card which concerns on embodiment of this invention is demonstrated.

  Here, when a user 4 holding a mobile phone 2 with an IC card 3 attached receives the point service information via the Internet using the mobile phone 2, the user 4 purchases the product at a store. The case where the privilege by the point service can be received will be described as an example.

  In the storage means of the IC card 3, use area information for limiting the available area where the IC card 3 can be used is registered in advance, but in the case shown in FIG. A rectangular area surrounded by four points, c and d, is specified and registered in advance as an available area where the IC card 3 can be used.

  Therefore, the place where the A store 5a exists is in an available area where the IC card 3 can be used, but the place where the B store 5b exists can be used where the IC card 3 cannot be used. Located outside.

  When the user 4 receives the point service information via the Internet using the mobile phone 2 on which the IC card 3 is mounted, the PIN stored in the storage means of the IC card 3 in the first stage When authentication information such as a personal identification number is used or when an electronic signature is made, key information or the like must be used. However, the IC card 3 reads out the information stored in these IC cards 3. The location is limited by the location of the attached mobile phone 2.

  That is, only when the mobile phone 2 to which the IC card 3 is attached is authenticated as existing in the available area of the use area information registered in the storage means of the IC card 3 in advance. The information stored in the storage means of the IC card 3 is restricted so that it can be read.

  Therefore, when the mobile phone 2 to which the IC card 3 is attached is out of the usable area, the information on the IC card 3 cannot be used, so that the point service cannot be received.

  In the case shown in FIG. 2, in the store A, the user receives a GPS signal transmitted from the GPS communication satellite 1 by the mobile phone 2 and calculates and detects position information by latitude and longitude. However, since it is authenticated that the IC card 3 is in an available area, the mobile phone 2 uses authentication information such as a PIN and a password stored in the storage means of the IC card 3. When performing an electronic signature, the key information is used to communicate with a server via the Internet, and a point service can be received.

  On the other hand, at the store B 5b, when the user receives the GPS signal transmitted from the GPS communication satellite 1 with the mobile phone 2, and calculates the position information based on the latitude and longitude, it is detected. Since the authentication cannot be received outside the available area where the card 3 can be used, the mobile phone 2 cannot use the information stored in the storage means of the IC card 3, even via the Internet. Even if communication with the server becomes possible, transaction processing is rejected and point service cannot be received.

  In this way, even for the same user, the use of information stored in the storage means of the IC card 3 is restricted depending on the use location.

  Next, the configuration of the mobile phone 2 as an example of the mobile terminal used in the IC card use area limiting system according to the embodiment of the present invention and the IC card detachably attached to the mobile phone 2 is shown in FIG.

  The GPS calculation means 12 has a function of calculating and detecting position information based on latitude and longitude based on the GPS signal received by the transmission / reception means 6. This position information is input / output control means (I / O) 15. Is controlled by the control means 16 so as to be sent to the IC card 3 via

  The IC card 3 includes an input / output control means (I / O) 17, a ROM 18, a RAM 19, an EEPROM 20, a CPU 21, and the like.

  The EEPROM 20 communicates with the server via the Internet by the use area information 22 that limits the area where the IC card 3 can be used and, if necessary, for example, the mobile phone 2 to which the IC card 3 is attached. Are stored for authentication information such as a PIN and personal identification number required for performing authentication processing and payment processing, or key information for electronic signatures.

  Further, the EEPROM 20 is provided with a flag writing area in which flag information 23 for determining whether or not to permit reading of information stored in the EEPROM 20 is stored. 23, information read management is performed.

  These processes are performed based on a processing program stored in the ROM 18 or the EEPROM 20.

  Further, the CPU 21 includes a collating unit 24, a flag writing unit 25, a control unit 26, and the like.

  The collation means 24 is stored in advance in the EEPROM 20 with position information based on the latitude and longitude detected based on the GPS signal input from the mobile phone 2 via the input / output control means (I / O) 17 of the IC card 3. It has a function of checking whether or not the location of the current location is within the area set by the use area information by collating with the use area information.

  Further, the flag rewriting means 25 enables the information stored in the EEPROM 20 to be read in the flag writing area of the EEPROM 20 when it is determined that the area is within the area as a result of the determination by the collating means 24. If the flag is set and if the result of determination by the collating means 24 is determined to be outside the area, the flag is set in the flag writing area of the EEPROM 20 so that the information stored in the EEPROM 20 cannot be read. It has a function to erase.
