  From here, the method, IC card system, and IC card according to the present invention will be described. FIG. 1 is a diagram for explaining an IC card issuing system to which a method according to the present invention is applied. The IC card issuing system illustrated in FIG. 1 is a system that includes at least a multi-application IC card 2 (hereinafter abbreviated as an IC card) and an issuing terminal 1, and adds / deletes applications to / from the IC card 2.

  In the IC card issuance system according to the present invention, the permitted number of times an application can be added / deleted to the IC card 2 is set in advance, and the number of times the application is added / deleted to / from the IC card 2 is stored and retained. When adding / deleting an application to / from 2, the number of times of permission is compared with the number of times of execution, thereby preventing an application from being added / deleted to the IC card 2 beyond the preset number of times of permission.

  In order to realize the present invention, either the issuing terminal 1 or the IC card 2 stores and holds the number of times of permission set in the IC card 2 and the number of times the application has been added / deleted to the IC card 2 In addition, either the issuing terminal 1 or the IC card 2 has a function of determining permission to add / delete an application.

  From here, the issuing terminal 1 stores / holds the number of times of permission set in the IC card 2, the IC card 2 stores / holds the number of times of execution, and the issuing terminal 1 determines permission of application addition / deletion. An example will be described.

  FIG. 2 is a block diagram of the issuing terminal 1. As shown in FIG. 2, the issuing means 14 for adding / issuing an application to the IC card 2 using the reader / writer 15, the permitted number obtaining means 10 for obtaining the permitted number set for the IC card 2, and the IC card 2, an execution number acquisition unit 11 for acquiring the number of executions of adding / deleting an application, an issue permission unit 12 for determining permission of addition / deletion of an application to / from the IC card 2, and at least a permission set for the IC card 2 A database 13 for storing the number of times is provided.

  In the present embodiment, the number of times of permission is stored in the database 13 in association with a unique card identifier for each IC card 2, and the number of times of permission acquisition unit 10 transmits a predetermined command to the IC card 2, whereby the IC card 2. The card identifier is read from, and the permission count associated with the card identifier is obtained from the database 13. Furthermore, since the execution count is stored in the IC card 2, the execution count acquisition unit 11 reads the execution count from the IC card 2 by transmitting a predetermined command.

  The issue permission unit 12 that determines whether to permit addition / deletion of an application to the IC card 2 compares the number of times of permission acquired by the number of times of permission acquisition unit 10 with the number of times of execution acquired by the number of times of execution acquisition unit 11. Only when the number of times of permission is less than the permitted number, addition / deletion of an application to / from the IC card 2 is permitted.

  From here, the operation of the issuing terminal 1 according to the present invention will be described with reference to FIG. 1 and FIG. This explanation also serves as an explanation of the method according to the present invention. FIG. 3 is a flowchart showing the operation of the issuing terminal 1.

  The first step S1 in the flow of FIG. 3 is a step in which the issuing terminal 1 receives a request to add / delete an application to / from the IC card 2. A request for adding / deleting an application to / from the IC card 2 is made when the administrator of the issuing terminal 1 or the owner of the IC card 2 operates the issuing terminal 1.

  The next step S <b> 2 is a step in which the issuing terminal 1 acquires the number of times of permission predetermined for the IC card 2. In this step, the permission count acquisition means 10 of the issuing terminal 1 reads the card identifier from the IC card 2 and acquires the permission count corresponding to the card identifier from the database 13.

  When the permitted number is stored in the IC card 2, the permitted number acquisition means 10 of the issuing terminal 1 transmits a command for reading the permitted number stored in the IC card 2 to the IC card 2. Get permission count from.

  The next step S3 is a step in which the issuing terminal 1 obtains the number of times the application has been added / deleted to the IC card 2. Since the number of executions is stored in the IC card 2, the execution number acquisition means 11 of the issuing terminal 1 transmits a command for reading the number of executions stored in the IC card 2 to the IC card 2 in this step. The number of executions is obtained from card 2.

  When the number of times of execution is stored in the issuing terminal 1, the number of times of execution obtaining unit 11 of the issuing terminal 1 determines the number of times of execution corresponding to the card identifier read from the IC card 2 from the database 13, as with the number of times of permission. get.

  The next step S4 is a step in which the issue permission unit 12 of the issuing terminal 1 compares the number of times of permission with the number of times of execution, and determines whether to permit addition / deletion of an application to the IC card 2. If the number of executions is equal to or greater than the permitted number, the issue permission unit 12 of the issuing terminal 1 determines that the addition / deletion of the application to / from the IC card 2 is not permitted, and proceeds to step S7 to add the application to the IC card 2 The process of canceling the deletion is executed, and the flow of FIG. 3 ends.

  If the number of executions is less than the permitted number in step S4, the issue permission unit 12 of the issuing terminal 1 determines that the addition / deletion of the application to the IC card 2 is permitted, and the process proceeds to step S5, where the application to the IC card 2 is determined. After the addition / deletion is performed, the number of executions is updated in step S6, that is, a process of incrementing the number of executions is executed, and the flow of FIG. 3 ends.

  When the number of executions is updated in step S4, a value obtained by incrementing the number of executions read from the IC card 2 in step S3 by one is preferably written in the IC card 2 as the number of executions.

(Modification 1)
The present invention is not limited to the embodiments described so far, and various modifications are possible. For example, in the embodiments described so far, the issuing terminal 1 has determined whether to permit addition / deletion of an application to / from the IC card 2, but the IC card 2 itself may determine not the issuing terminal 1. .

  When the IC card 2 itself determines permission to add / delete an application to / from the IC card 2, the IC card 2 is provided with means having the same function as the issue permission means 12 of the issuing terminal 1, and the steps of FIG. Steps S2, S3, S4, and S6 are processes executed by the IC card 2.

  When the IC card 2 itself does not store or hold the number of times of permission or the number of times of execution, the IC card 2 includes a command for obtaining the number of times of permission or the number of times of execution from the issuing terminal 1, and step S2 in FIG. In step S3, these commands are transmitted from the issuing terminal 1 to the IC card 2, and the IC card 2 acquires the number of times of permission and the number of times of execution.

(Modification 2)
From here, the modification which provides the frequency | count of permission and the frequency | count of implementation for every application is demonstrated. By storing and holding the number of times of permission and the number of times of execution for each application, it becomes possible to prevent the addition / deletion of the application exceeding the permitted number of times for each application.

  Furthermore, in addition to the number of times of permission and the number of times of execution for each application, the card issuer and the application provider set different times of permission and number of times by storing and holding the number of times of permission and the number of times of the entire IC card 2 as well. become able to.

  At this time, the permitted number of times set for the entire IC card 2 is stored in the database 13 in association with the card identifier in the database 13 of the issuing terminal 1, and the permitted number of times set for each application is a unique application for each application. The permitted number of times is stored in the database 13 in association with the identifier.

  Further, the number of executions of the entire IC card 2 is stored in the IC card 2 as security information of the entire IC card 2 such as the card expiration date, and the number of executions for each application is stored in the IC card 2 in association with the application identifier.

  FIG. 4 is a flowchart showing the operation of the issuing terminal 1 in the second modification. The content of step S10 in FIG. 4 is the same as the content of step S1 in FIG. Step S11 in FIG. 4 is a step in which the issuing terminal 1 acquires the number of times of permission of the entire IC card 2. In this step, the permission count acquisition means 10 of the issuing terminal 1 reads the card identifier from the IC card 2 and acquires the permission count corresponding to the card identifier from the database 13.

  The next step S12 is a step in which the issuing terminal 1 acquires the number of implementations of the entire IC card 2. Since the number of executions is stored in the IC card 2, in this step, the execution number acquisition means 11 of the issuing terminal 1 transmits a command for reading the number of executions stored as security information to the IC card 2. 2 to obtain the number of implementations of the entire IC card 2.

  Step S13, which is executed after step S12, is a step of comparing whether the number of times of permission of the entire IC card 2 and the number of times of execution of the entire IC card 2 are compared, and determining whether addition / deletion of an application to the IC card 2 can be permitted. If the number of implementations of the entire IC card 2 is equal to or greater than the total number of permits of the IC card 2, the issuance permission unit 12 of the issuing terminal 1 determines that application addition / deletion to the IC card 2 is not permitted, and proceeds to step S19. Then, the process of canceling the addition / deletion of the application to the IC card 2 is executed, and the flow of FIG.

  If it is determined in step S13 that the number of implementations of the entire IC card 2 is less than the total number of permits of the IC card 2, the process proceeds to step S14, and the permitted number acquisition means 10 of the issuing terminal 1 stores the database of the issuing terminal 1 as in step S11. From 13, the number of times of permission stored in association with the application identifier of the application to be added / deleted is acquired.

  The next step S15 is a step in which the execution number acquisition unit 11 of the issuing terminal 1 acquires the number of executions in which the application has been added / deleted. The execution frequency acquisition means 11 of the issuing terminal 1 reads the execution frequency of the application to be added / deleted from the IC card 2 by designating the application identifier of the application from which the execution frequency is read.

  The next step S16 is a step in which the issue permission unit 12 of the issuing terminal 1 compares the number of times the application is permitted and the number of times the application is executed, and determines whether to permit addition / deletion of the application to the IC card 2.

  The issue permission unit 12 of the issue terminal 1 determines that the addition / deletion of the application to the IC card 2 is not permitted when the application execution count is equal to or greater than the application allowance number, Proceeding to step S19, processing for canceling addition / deletion of an application to / from the IC card 2 is executed, and the flow of FIG. 4 ends.

  If the application execution count is less than the application permission count in step S16, the issue permission means 12 of the issuing terminal 1 determines that the addition / deletion of the application to / from the IC card 2 is permitted, and proceeds to step S17. 2 is added / deleted, and the number of implementations of the IC card 2 and the number of implementations of the application are updated in step S18, and the flow of FIG. 4 ends.

(Modification 3)
Until now, the number of times the IC card 2 was permitted was stored and held in the issuing terminal 1 or the IC card 2, but it was permitted from the expiration date stored in the IC card 2 (or the manufacturing date of the IC card 2). The number of times may be changed in stages.

  At this time, the issuing permission means 12 of the issuing terminal 1 changes the number of times of permission based on the expiration date (or the date of manufacture of the IC card 2) stored in the IC card 2, and uses the number of times of permission after the change for the IC. Judgment of permission of addition / deletion of application to / from card 2.

The operation of the issuing terminal 1 when changing the permitted number of times from the expiration date (or the date of manufacture of the IC card 2) stored in the IC card 2 is not different from the contents described in FIG. 3 and FIG. In step 2 of FIG. 3 and step S11 of FIG. 4, the permitted number acquisition means 10 of the issuing terminal 1 acquires the expiration date (or the date of manufacture of the IC card 2) from the IC card 2 instead of the permitted number.

  Then, in step S4 in FIG. 3 and step S13 and step S16 in FIG. 4, the issue permission unit 12 of the issuing terminal 1 changes the permitted number from the IC card 2 from the expiration date (or the date of manufacture of the IC card 2). Then, the permission of addition / deletion of the application to the IC card 2 is determined by comparing the number of times of permission after the change with the number of times of execution.

  When the issuance permission means 12 of the issuing terminal 1 changes the number of times of permission from the expiration date acquired from the IC card 2 (or the manufacturing date of the IC card 2), processing for adding / deleting an application to the IC card 2 is executed. The remaining number of days (or the number of days elapsed from the date of manufacture of the IC card 2) from the date on which the IC card 2 was manufactured is obtained, and the number of times the IC card 2 is permitted according to the number of remaining days (or the number of days elapsed from the date of manufacture of the IC card 2). It is good to change.

  FIG. 5 is an example of a table used when changing the number of times the IC card 2 is permitted from the expiration date acquired from the IC card 2. The issue permission means 12 of the issuing terminal 1 includes a table as shown in FIG. 5 that associates the number of remaining days until the expiration date with the number of times of permission, and acquires the number of times of permission according to the number of remaining days until the expiration date.

  When the number of permits is changed in stages according to the number of days remaining until the expiration date (or the number of days elapsed from the date of manufacture), the number of implementations up to that point is reset and the judgment is made based on the number of permits within that period, or By recording the number of executions separately for each period, it is preferable to perform management independent of the number of executions of the addition / deletion processing performed before that period.

  Further, as shown in the flow of FIG. 4, when storing and holding the number of times of permission and execution of the entire IC card 2 and the number of times of permission and execution of each application, the expiration date of the entire IC card 2 (or If the total number of times of permission of the IC card 2 is calculated from the manufacturing date of the IC card 2 and the number of times of permission for each application is changed from the expiration date of the application (or the date when the application is added / deleted). Good.
