Next, the hardware configuration of the IC card 1 of this embodiment will be described with reference to FIG.
FIG. 2 is a diagram illustrating a hardware configuration example of the IC card 1 according to the present embodiment.
As shown in FIG. 2, the IC card 1 includes an IC module 10 including a contact portion 3 and an IC chip 100. The IC chip 100 includes a communication unit 4, a CPU 5, a ROM (Read Only Memory) 6, a RAM (Random Access Memory) 7, and an EEPROM (Electrically Erasable Programmable ROM) 8.

The communication unit 4 performs communication (command / response transmission / reception) between the IC card 1 and the external device 2. For example, the communication unit 4 receives various commands such as a write request (write command) for storing information in a predetermined area of the EEPROM 8 (storage unit) from the external device 2. In addition, the communication unit 4 transmits a response that is a result of execution of processing according to various commands to the external device 2.
The CPU 5 executes programs stored in the ROM 6 or the EEPROM 8 to perform various processes of the IC card 1. For example, the CPU 5 executes command processing corresponding to the command received by the communication unit 4 via the contact unit 3.

The ROM 6 is a non-volatile memory such as a mask ROM, for example, and stores a program for executing various processes of the IC card 1 and data such as a command table.
The RAM 7 is a volatile memory such as SRAM (Static RAM), for example, and temporarily stores data used when performing various processes of the IC card 1.

  The EEPROM 8 is, for example, an electrically rewritable nonvolatile memory. The EEPROM 8 stores various data used by the IC card 1. The EEPROM 8 stores, for example, a user name, a user ID, a card ID, various key information, and the like according to the use of the IC card 1.

Next, a functional configuration example of the IC card 1 according to the present embodiment will be described with reference to FIG.
FIG. 3 is a block diagram showing a functional configuration example of the IC card 1 of the present embodiment.
As shown in FIG. 3, the IC card 1 includes a communication unit 4, a control unit 50, and a data storage unit 80.
Here, each part of the IC card 1 shown in FIG. 3 is realized by using the hardware of the IC card 1 shown in FIG.

The data storage unit 80 is a storage unit configured by, for example, the EEPROM 8. The data storage unit 80 includes, for example, a management area 81 and a data area 82.
The management area 81 manages information used by the OS (operating system) of the IC card 1 and files and areas for storing data and key information stored in the data area 82 according to the use of the IC card 1. The information is memorized.
The data area 82 stores various data and key information in a predetermined area managed by the management area 81. The predetermined area is defined as an area in a file, logical record, or TLV (Tag Length Value) format. Further, when information (data) is stored in the predetermined area defined as a file, logical record, or TLV area, area identification information (for example, file ID, record ID, Tag ID).

  The temporary setting information storage unit 60 is a storage unit configured by the ROM 6, for example. The temporary setting information storage unit 60 stores in advance temporary setting information to be stored in the predetermined area corresponding to the area identification information described above. This temporary setting information is, for example, information stored in advance in the temporary setting information storage unit 60 as a default value (initial setting value) of each area. The temporary setting information storage unit 60 stores, for example, region identification information and temporary setting information in association with each other.

  The control unit 50 is realized by, for example, the CPU 5, the RAM 7, and the ROM 6 or the EEPROM 8, and comprehensively controls the IC card 1. For example, the control unit 50 executes processing of various commands (command processing) transmitted from the external device 2 to the IC card 1. The control unit 50 includes a write processing unit 51, for example.

  When the write request received by the communication unit 4 is set to the first state including the area identification information and the information to be written in the predetermined area corresponding to the area identification information, the write processing unit 51 A first process for storing the information to be written in the predetermined area is executed. Here, the write request is a write command for executing a process of writing information in a predetermined area of the data storage unit 80. The write command includes, for example, a STORE DATA command, a PUT DATA command, a WRITE RECORD command, a WRITE BINARY command, and the like.

  Further, the write processing unit 51 includes the region identification information in the write request received by the communication unit 4, and the write request is set to the second state that is a specific state different from the first state. If so, the second process is executed. Here, the second process is a process different from the first process, and is a process related to information stored in the predetermined area corresponding to the area identification information. For example, the writing processing unit 51 stores the temporary setting information stored in advance in the temporary setting information storage unit 60 in a predetermined area corresponding to the area identification information.

  In addition, the second state described above includes, for example, a state in which information to be written in a predetermined area corresponding to the area identification information is not included (a state in which the length (data size) of write data is “0”). It is. That is, the write processing unit 51 includes the second process described above when the write request includes the area identification information and does not include the information to be written in the predetermined area corresponding to the area identification information. Execute.

Here, a specific command example of the first state and the second state in the write command will be described.
First, as an example of writing information in a predetermined area in the TLV format, the first state and the second state in the STORE DATA command will be described with reference to FIGS.

FIG. 4 is a diagram illustrating a first state of the STORE DATA command according to the present embodiment.
The example shown in FIG. 4 shows an APDU (Application Protocol Data Unit) in the first state of the STORE DATA command. In the APDU in the first state of the STORE DATA command, for example, “CLA” (class byte) is a predetermined value, and “INS” (instruction byte) is “E2h”. Here, “h” indicates hexadecimal (hexadecimal number).

In “P1” (parameter 1) and “P2” (parameter 2), whether or not the command is the final command when the write data is transmitted divided into a plurality of commands, the presence or absence of encryption, and the sequence Is set. “Lc” is set to the length (length) “XXh” of “Command Data”, and “Command Data” is set to TLV format write data. Here, the write data in the TLV format includes a tag ID, “XXh” (write data length), and write data, and an area (predetermined area) in which the write data is stored is designated by the tag ID.
When the communication unit 4 receives the STORE DATA command set to the first state as shown in FIG. 4, the write processing unit 51 performs the first processing in the area indicated by the tag ID of the data storage unit 80. Write data is stored.

FIG. 5 is a diagram illustrating a second state of the STORE DATA command according to the present embodiment.
The example shown in FIG. 5 shows the APDU in the second state of the STORE DATA command. In the APDU in the second state of the STORE DATA command, for example, “CLA”, “INS”, “P1”, and “P2” are the same as in the first state. In addition, “Command Data” length “XXh” is set in “Lc”, tag ID and “00h” are set in “Command Data”, and write data is stored as in the first state. Not included. Here, “00h” corresponds to the length of the TLV format, and there is no write data, so this value is designated.

  When the communication unit 4 receives the STORE DATA command set to the second state as shown in FIG. 5, the write processing unit 51 stores the temporary setting information stored in the temporary setting information storage unit 60 as the second processing. Of the information, temporary setting information corresponding to the tag ID is stored in the area indicated by the tag ID. That is, when the communication unit 4 receives the STORE DATA command set to the second state, the write processing unit 51 copies the temporary setting information stored in the temporary setting information storage unit 60 to the area indicated by the tag ID. To do.

  Next, as an example of writing information in a predetermined area of the file format, the first state and the second state in the PUT DATA command will be described with reference to FIGS.

FIG. 6 is a diagram illustrating a first state of the PUT DATA command according to the present embodiment.
The example shown in FIG. 6 shows the APDU in the first state of the PUT DATA command. In the APDU in the first state of the PUT DATA command, for example, “CLA” is a predetermined value, and “INS” is “DAh”.

In addition, tags that are identification information for identifying data objects are set in “P1” and “P2”. Here, the “tag” is a tag representing a data object (one or a plurality) of a writing destination. “Lc” is set to the length (length) “XXh” of “Command Data”, and “Command Data” is set to write data. Here, an area (predetermined area) for storing write data is specified by the tag.
When the communication unit 4 receives the PUT DATA command set to the first state as shown in FIG. 6, the write processing unit 51 performs, as a first process, an area (data) indicated by the tag of the data storage unit 80. Write data to the object).

FIG. 7 is a diagram illustrating a second state of the PUT DATA command according to the present embodiment.
The example shown in FIG. 7 shows an APDU in the second state of the PUT DATA command. In the APDU in the second state of the PUT DATA command, for example, “CLA”, “INS”, “P1”, and “P2” are the same as in the first state. Also, “00h” is set in “Lc”, and “Command Data” (write data) is not included as in the first state.

  When the communication unit 4 receives the PUT DATA command set in the second state as illustrated in FIG. 7, the write processing unit 51 stores the temporary setting information stored in the temporary setting information storage unit 60 as the second processing. Of the information, temporary setting information corresponding to the tag is stored in an area (data object) indicated by the tag. In other words, when the communication unit 4 receives the PUT DATA command set to the second state, the write processing unit 51 stores the temporary setting information stored in the temporary setting information storage unit 60 in the area (data object) indicated by the tag. Copy the information.

Next, the operation of the IC card 1 according to the present embodiment will be described with reference to the drawings.
FIG. 8 is a flowchart showing an example of the operation of the write command of this embodiment.

  In FIG. 8, the IC card 1 first determines whether or not a write command has been received (step S101). The control unit 50 of the IC card 1 determines whether or not a write command has been received by the communication unit 4. When the write command is received (step S101: YES), the control unit 50 advances the process to step S102. In addition, when the write command is received (step S101: NO), the control unit 50 returns the process to step S101 and repeatedly executes the process of step S101.

  In step S <b> 102, the write processing unit 51 of the control unit 50 determines whether write data is included in the write command received by the communication unit 4. That is, the write processing unit 51 determines whether or not the received write command is set to the first state as shown in FIGS. 4 and 6 described above. If the write data is included (in the first state) (step S102: YES), the write processing unit 51 advances the process to step S103. If the write data is not included (in the second state as shown in FIG. 5 and FIG. 7 described above) (step S102: NO), the write processing unit 51 advances the process to step S104.

  In step S103, the write processing unit 51 stores the write data in the designated area. That is, the write processing unit 51 stores the received write data in a predetermined area corresponding to the area identification information (for example, tag ID) as the first process. After the process of step S103, the write processing unit 51 advances the process to step S105.

  In step S104, the write processing unit 51 stores temporary setting information in the designated area. That is, the write processing unit 51 stores the temporary setting information stored in advance in the temporary setting information storage unit 60 in a predetermined area corresponding to the area identification information (for example, tag ID) as the second process. . Here, with reference to FIG. 9, a specific example of the second process when the write command is a STORE DATA command will be described.

  FIG. 9 is a diagram illustrating an example of the operation of the write command according to the present embodiment. In this figure, before execution of the STORE DATA command, the area where the tag ID is “0001” and the data length (length) is “04” is the state ST1 in which the data is blank. The temporary setting information storage unit 60 stores “AAAAAAAAAh” as temporary setting information D1.

  In such a state ST1, when the STORE DATA command set in the second state is executed, the write processing unit 51 uses “AAAAAAAAAh” as the temporary setting information D1 as the tag ID as the second process. Is stored in the area “0001”. As a result, after execution of the STORE DATA command, the area with the tag ID “0001” and the data length (length) “04” is in the state ST2 in which “AAAAAAAAAh” is written as data.

Further, after the processing in step S104, the writing processing unit 51 advances the processing to step S105.
Next, in step S <b> 105, the write processing unit 51 transmits a response, which is the execution result of the write command, to the external device 2 via the communication unit 4. After the process of step S105, the write processing unit 51 returns the process to step S101.

Next, a procedure for issuing the IC card 1 having the above-described write command will be described with reference to FIG.
FIG. 10 is a flowchart showing an example of the issuing process of the IC card 1 of the present embodiment.
First, the IC card 1 is subjected to an issuing process (first issuing process) by a manufacturer (manufacturer) of the IC card 1 (step S200). That is, the manufacturer's manufacturing device or issuing device executes a first issuing process on the IC card 1.

  Specifically, in the first issuing process of step S200, the manufacturer's issuing device defines, for example, a file and key information area (step S201). The issuing device of the manufacturer stores information defining (specifying) a file and key information area according to the application in the management area 81 of the data storage unit 80 of the IC card 1.

Next, in the first issue process of step S200, the manufacturer's issuing device writes, for example, basic information (step S202). The manufacturer's issuing device stores basic information (for example, temporary key information, system management information, etc.) according to the application in the data area 82 of the data storage unit 80.
The IC card 1 is shipped to a card issuer (issuing company) in a state where the first issuing process of step S200 has been executed.

  Next, the issue process (second issue process) of the IC card 1 is executed by the issuer of the IC card 1 (step S210). That is, the issuer of the issuer executes a second issue process for writing detailed information on the IC card 1.

  Specifically, in the second issuance process in step S210, the issuer device of the issuer writes the user name by, for example, “STORE DATA command (1)” set in the first state (step S211). . In other words, the issuing device of the issuer transmits a STORE DATA command in which tag ID = “0001” and write data = user name are sent to the IC card 1, and the user name is placed in the area where the tag ID is “0001”. Remember.

  Next, the issuing device of the issuer writes the user ID by, for example, the “STORE DATA command (2)” set in the first state (step S212). That is, the issuing device of the issuer transmits a STORE DATA command in which tag ID = “0002” and write data = user ID are transmitted to the IC card 1, and the user ID is placed in the area of the tag ID “0002” Remember.

Next, the issuing device of the issuer writes the user contact information by, for example, “STORE DATA command (3)” set in the first state (step S213). That is, the issuing device of the issuer transmits a STORE DATA command in which tag ID = “0003” and write data = user contact information to the IC card 1, and the user enters the area where the tag ID is “0003”. Remember contact information.
In this way, in the second issue process of step S210, as shown in steps S211 to S213, the issuer device of the issuer sends the STORE DATA command set to the first state to the IC card 1. For example, detailed information different for each user is stored in a predetermined area.

  Next, in the second issue process of step S210, the issuer's issue device transmits, for example, “STORE DATA command (4)” set to the second state (step S214). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0004”, write data = blank (data length is “00h”, no write data) to the IC card 1. In this case, as the second process, the write processing unit 51 stores the temporary setting information corresponding to the area with the tag ID “0004” stored in the temporary setting information storage unit 60 in advance, and the tag ID “0004”. It memorize | stores in the area | region of.

  Next, the issuing device of the issuer transmits, for example, “STORE DATA command (5)” set in the second state (step S215). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0005”, write data = blank (data length is “00h”, no write data) to the IC card 1. In this case, as the second process, the writing processing unit 51 stores the temporary setting information corresponding to the area with the tag ID “0005” stored in the temporary setting information storage unit 60 in advance, and the tag ID “0005”. It is memorized in the area.

  Next, the issuing device of the issuer transmits, for example, “STORE DATA command (6)” set in the second state (step S216). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0006”, write data = blank (data length is “00h”, no write data) to the IC card 1. In this case, as the second process, the writing processing unit 51 stores the temporary setting information corresponding to the area with the tag ID “0006” stored in the temporary setting information storage unit 60 in advance, and the tag ID “0006”. It is memorized in the area.

  As described above, in the second issue process of step S210, as shown in steps S214 to S216, the issuer device of the issuer transmits the STORE DATA command set to the second state to the IC card 1. Temporary setting information stored in advance in the temporary setting information storage unit 60 (for example, not different information for each user but the same detailed information for a plurality of users) is stored in a predetermined area.

  As described above, the IC card 1 according to the present embodiment includes the communication unit 4 and the write processing unit 51. The communication unit 4 receives a write request (for example, a write command) for storing information in a predetermined area of the data storage unit 80 (storage unit). The write processing unit 51 includes area identification information (for example, a tag ID) and information (write data) to be written in the predetermined area identified by the area identification information, in the write request received by the communication unit 4. In the first state, the first process is executed. That is, when the communication unit 4 receives the write command set to the first state, the write processing unit 51 stores the received write data in the predetermined area as the first process. In addition, the write processing unit 51 includes the region identification information in the write request received by the communication unit 4 and the write request is in a second state that is a specific state different from the first state. In addition, the second process is executed. That is, when the communication unit 4 receives the write command set in the second state, the write processing unit 51 is a process different from the first process, and the predetermined processing corresponding to the area identification information is performed. A second process related to information stored in the area is executed.

  Thereby, the IC card 1 according to the present embodiment can shorten the time required for issuing. That is, the IC card 1 according to the present embodiment uses a write request (for example, a write command) set in the second state, for example, when storing the same detailed information in a plurality of users. There is no need to send write information (write data) to the IC card 1. Therefore, the IC card 1 according to the present embodiment can reduce the time required for issuance (issuer issue processing) even when issuing a large number of cards via a relatively low-speed communication interface. it can. In addition, the IC card 1 according to the present embodiment can reduce the processing amount required for issuing (the effort required for issuing).

In the present embodiment, the second state is a state in which information to be written in the predetermined area corresponding to the area identification information is not included (for example, the data length (length) is “0”, and the write data Is not included). The write processing unit 51 executes the second process when the write request includes the area identification information and does not include the information to be written in the predetermined area corresponding to the area identification information.
As a result, the IC card 1 according to the present embodiment can execute the second process by a simple method of setting a state in which information to be written in a conventional write command is not included. Further, since the IC card 1 according to the present embodiment can use the first process according to the first state which is the conventional setting as it is, it is not necessary to add a new write command for executing the second process. The time required for issuing (issuer issue process) can be shortened. By using the IC card 1 according to the present embodiment, the issuing device shortens the time required for issuing (issuer issue processing) by a simple change in which the second state is associated with a conventional write command. Can do.

Further, the IC card 1 according to the present embodiment includes a temporary setting information storage unit 60 that stores in advance temporary setting information to be stored in the predetermined area corresponding to the area identification information. As the second process, the writing processing unit 51 executes a process of storing the temporary setting information stored in advance in the temporary setting information storage unit 60 in a predetermined area corresponding to the area identification information.
Thereby, in the IC card 1 according to the present embodiment, when the temporary setting information is used as it is, it is not necessary for the external device 2 to transmit information to be written (for example, write data) to the IC card 1 and issue The time required for the issuer process can be shortened.

  In addition, the IC card 1 according to the present embodiment has, for example, a first state and a second state when both a card that writes data having the same content and a card that does not write the data are issued. Can be appropriately handled by switching between and executing the write command.

  Further, the IC module 10 according to the present embodiment includes a communication unit 4 and a write processing unit 51, similarly to the IC card 1. Therefore, like the IC card 1, the IC module 10 according to the present embodiment can reduce the time required for issuing.

(Second Embodiment)
Next, an IC card according to the second embodiment will be described with reference to the drawings.
FIG. 11 is a block diagram illustrating a functional configuration example of the IC card 1a of the present embodiment.

In this figure, the same components as those shown in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted.

  The IC card 1a of the present embodiment is different from the first embodiment in that it does not include the temporary setting information storage unit 60 but includes a write processing unit 51a of the control unit 50a and a management area 81a of the data storage unit 80a. .

The data storage unit 80a is a storage unit configured by the EEPROM 8, for example. The data storage unit 80a includes, for example, a management area 81a and a data area 82.
The management area 81a stores information used to manage files and areas for storing information used by the OS of the IC card 1a, data stored in the data area 82 according to the use of the IC card 1a, and key information. To do. The management area 81a stores, for example, validation information indicating whether or not a file or TLV format area is valid. For example, the management area 81a stores area identification information and validation information in association with each other. For example, the management area 81a stores “0” as the validation information when the corresponding predetermined area is invalid. In addition, the management area 81a stores “1” as the validation information when the corresponding predetermined area is in a valid state, for example.

The control unit 50a is realized by, for example, the CPU 5, the RAM 7, and the ROM 6 or the EEPROM 8, and comprehensively controls the IC card 1a. The control unit 50a includes, for example, a write processing unit 51a.
When the communication unit 4 receives the write command set to the first state, the write processing unit 51a executes the first process as in the first embodiment. When executing the first process, the write processing unit 51a sets the validation information of the management area 81a corresponding to the designated area identification information to “1”, and the data storage area corresponding to the area identification information Enable 82 predetermined areas.

  Further, when the communication unit 4 receives the write command set in the second state, the write processing unit 51a validates information stored in advance in a predetermined area as the second process. Here, information (for example, provisional setting information) is stored in advance in a predetermined area corresponding to the area identification information, and the write processing unit 51a determines whether the management area 81a corresponding to the area identification information is valid. The activation information is set to “1” to enable a predetermined area. In this case, as in the first embodiment, the IC card 1a does not need to receive write data from the external device 2.

Next, the operation of the IC card 1a according to the present embodiment will be described with reference to the drawings.
FIG. 12 is a flowchart showing an example of the operation of the write command of this embodiment.

In FIG. 12, the processing of step S301, step S302, and step S306 is the same as the processing of step S101, step S102, and step S105 shown in FIG.
In this embodiment, in step S302, the write processing unit 51a advances the process to step S303 when write data is included (in the first state) (step S302: YES). If the write data is not included (in the second state as shown in FIGS. 5 and 7 described above) (step S302: NO), the write processing unit 51a advances the process to step S305.

In step S303, the write processing unit 51a stores the write data in the designated area. That is, the write processing unit 51a stores the received write data in a predetermined area corresponding to the area identification information (for example, tag ID) as the first process.
Next, the write processing unit 51a sets the validation information of the management area 81a corresponding to the designated area identification information to “1”, and validates the predetermined area (step S304). After the process of step S304, the write processing unit 51a advances the process to step S306.

  In step S305, the write processing unit 51a validates the designated area. That is, as the second process, the write processing unit 51a validates the management area 81a corresponding to the designated area identification information in order to validate the write data stored in the designated predetermined area. Is set to “1” to enable a predetermined area. Here, a specific example of the second process when the write command is a STORE DATA command in the present embodiment will be described with reference to FIG.

  FIG. 13 is a diagram illustrating an example of the operation of the write command according to the present embodiment. In this figure, before execution of the STORE DATA command, the area with the tag ID “0001” and the data length (length) “04” is the state ST3 in which the data “AAAAAAAAAh” is stored in advance. In the management area 81a, “0” is stored as the validation information D2.

In this state ST3, when the STORE DATA command set to the second state is executed, the write processing unit 51a activates the area with the tag ID “0001” as the second process. In addition, the validation information in the management area 81a corresponding to the area with the tag ID "0001" is changed to "1" to make the validation information D3 state. As a result, after execution of the STORE DATA command, the area with the tag ID “0001” and the data length (length) “04” becomes valid in the state ST3 in which “AAAAAAAAAh” is written as data, and the tag ID is changed. Data “AAAAAAAAAh” in the area “0001” can be used.
In addition, after the process of step S305, the write processing unit 51a advances the process to step S306.

Next, a procedure for issuing the IC card 1a having the write command described above will be described with reference to FIG.
FIG. 14 is a flowchart illustrating an example of the issuing process of the IC card 1a according to the present embodiment.
First, the IC card 1a is subjected to an issuing process (first issuing process) by the manufacturer (manufacturer) of the IC card 1a (step S400). That is, the manufacturer's manufacturing device or issuing device executes a first issuing process on the IC card 1a.

Specifically, in the first issue process of step S400, the processes of step S401 and step S402 are the same as the processes of step S201 and step S202 shown in FIG.
In step S403, the manufacturer's issuing device stores, for example, temporary setting information in a predetermined area. When the manufacturer's issuing device stores the temporary setting information in a predetermined area, the activation information corresponding to the predetermined area of the management area 81a of the IC card 1a is set to “0” (invalid state). deep.
The IC card 1a is shipped to a card issuer (issuing company) in a state where the first issuing process of step S400 is executed.

  Next, the issue process (second issue process) of the IC card 1a is executed by the issuer of the IC card 1a (step S410). That is, the issuer of the issuer executes a second issue process for writing detailed information to the IC card 1a.

In the second issue process of step S410, the process from step S411 to step S413 is the same as the process from step S211 to step S213 shown in FIG. 10 described above, and the description thereof is omitted here.
In the second issuance process in step S410, as shown in steps S411 to S413, the issuer device of the issuer transmits the STORE DATA command set in the first state to the IC card 1a to use, for example, Detailed information that differs for each person is stored in a predetermined area.

  Next, in the second issue process of step S410, the issuer device of the issuer transmits, for example, “STORE DATA command (4)” set to the second state (step S414). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0004”, write data = blank (data length is “00h”, no write data) to the IC card 1a. In this case, the write processing unit 51a executes a process of enabling the area with the tag ID “0004” as the second process. That is, the write processing unit 51a changes the validation information corresponding to the area with the tag ID “0004” to “1”, and validates the area with the tag ID “0004”.

  Next, the issuing device of the issuer transmits, for example, “STORE DATA command (5)” set in the second state (step S415). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0005”, write data = blank (data length is “00h”, no write data) to the IC card 1a. In this case, the write processing unit 51a executes a process for validating the area having the tag ID “0005” as the second process. That is, the write processing unit 51a changes the validation information corresponding to the area with the tag ID “0005” to “1”, and validates the area with the tag ID “0005”.

  Next, the issuing device of the issuer transmits, for example, “STORE DATA command (6)” set in the second state (step S416). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0006”, write data = blank (data length is “00h”, no write data) to the IC card 1a. In this case, the write processing unit 51a executes a process for validating the area with the tag ID “0006” as the second process. That is, the write processing unit 51a changes the validation information corresponding to the area with the tag ID “0006” to “1”, and validates the area with the tag ID “0006”.

  As described above, in the second issue process of step S510, as shown in steps S414 to S416, the issuer device of the issuer transmits the STORE DATA command set to the second state to the IC card 1a. Temporary setting information stored in the data area 82 in advance (for example, not different information for each user but the same detailed information for a plurality of users) is validated.

As described above, in the IC card 1a according to the present embodiment, information (for example, temporary setting information) is stored in advance in a predetermined area corresponding to the area identification information. As the second process, the write processing unit 51a executes a process of validating information (for example, temporary setting information) stored in advance in a predetermined area.
Thus, when the IC card 1a according to the present embodiment uses the information (for example, temporary setting information) stored in the data storage unit 80a as it is, the external device stores the information to be written (for example, write data). There is no need to transmit to the IC card 1a, and the time required for issuing (issuer issue process) can be shortened.

  In the present embodiment, the predetermined area in which the temporary setting information is stored in advance is in an invalid state before the issuing process, and therefore, the predetermined area in which the temporary setting information is stored in advance. When the temporary setting information is not used, the issuing device of the issuer does not need to send a write command to the IC card 1a.

(Third embodiment)
Next, an IC card 1a according to a third embodiment will be described with reference to the drawings.
The IC card 1a of the present embodiment is a modification of the second embodiment, and the external view, hardware configuration, and functional configuration of the IC card 1a are the same as those of the second embodiment, and thus description thereof is omitted. In the IC card 1a of this embodiment, the processing of the write processing unit 51a is different from that of the second embodiment, and the processing of the write processing unit 51a of this embodiment will be described.

In this embodiment, information (for example, temporary setting information) is stored in advance in a predetermined area corresponding to the area identification information, and the predetermined area in which the temporary setting information is stored in advance is Before, it is in a valid state. That is, the activation information corresponding to the predetermined area of the management area 81a of the IC card 1a is “1” (valid state).
As a second process, the write processing unit 51a of the present embodiment sets the validation information corresponding to a predetermined area of the management area 81a to “0” and invalidates it. In this case, as in the first and second embodiments, the IC card 1a does not need to receive write data from the external device 2.

Next, the operation of the IC card 1a according to the present embodiment will be described with reference to the drawings.
FIG. 15 is a flowchart illustrating an example of the operation of the write command according to the present embodiment.

In FIG. 15, the processing of step S501, step S502, and step S505 is the same as the processing of step S101, step S102, and step S105 shown in FIG.
In this embodiment, in step S502, the write processing unit 51a advances the process to step S503 when write data is included (in the first state) (step S502: YES). If the write data is not included (in the second state as shown in FIGS. 5 and 7 described above) (step S502: NO), the write processing unit 51a advances the process to step S504.

  In step S503, the write processing unit 51a stores write data in the designated area. That is, the write processing unit 51a stores the received write data in a predetermined area corresponding to the area identification information (for example, tag ID) as the first process. After the process of step S503, the write processing unit 51a advances the process to step S505.

  In step S504, the write processing unit 51a invalidates the designated area. That is, as the second process, the write processing unit 51a invalidates the write data stored in the specified predetermined area, and the activation information of the management area 81a corresponding to the specified area identification information Is set to “0” to invalidate a predetermined area. That is, the write processing unit 51a externally sets the same state as the state where a predetermined area is erased. Here, a specific example of the second process when the write command is a STORE DATA command in the present embodiment will be described with reference to FIG.

  FIG. 16 is a diagram illustrating an example of the operation of the write command according to the present embodiment. In this figure, before execution of the STORE DATA command, the area with the tag ID “0001” and the data length (length) “04” is the state ST4 in which the data “AAAAAAAAAh” is stored in advance. In the management area 81a, “1” is stored as the validation information D4.

In such a state ST4, when the STORE DATA command set to the second state is executed, the write processing unit 51a invalidates the area having the tag ID “0001” as the second process. In addition, the validation information in the management area 81a corresponding to the area with the tag ID “0001” is changed to “0” to make the validation information D5 state. As a result, after execution of the STORE DATA command, the area with the tag ID “0001” and the data length (length) “04” becomes invalid in the state ST4 in which “AAAAAAAAAh” is written as data, and the tag ID is changed. The data “AAAAAAAAAh” in the area “0001” becomes unusable. Here, “the data in the area becomes unusable” indicates that the IC card 1a does not exist when the write or read command with the tag ID “0001” is received. The error information is sent as a response.
In addition, after the processing in step S504, the write processing unit 51a advances the processing to step S505.

Next, a procedure for issuing the IC card 1a according to the present embodiment will be described with reference to FIG.
FIG. 17 is a flowchart showing an example of the issuing process of the IC card 1a of this embodiment.
First, the IC card 1a is subjected to an issuing process (first issuing process) by a manufacturer (manufacturer) of the IC card 1a (step S600). That is, the manufacturer's manufacturing device or issuing device executes a first issuing process on the IC card 1a.

Specifically, in the first issue process of step S600, the processes of step S601 and step S602 are the same as the processes of step S201 and step S202 shown in FIG.
In step S603, the manufacturer's issuing device stores, for example, temporary setting information in a predetermined area. When the manufacturer's issuing device stores the temporary setting information in a predetermined area, the activation information corresponding to the predetermined area of the management area 81a of the IC card 1a is set to “1” (valid state). deep.
The IC card 1a is shipped to the card issuer (issuing company) in a state where the first issuing process of step S600 has been executed.

  Next, the issue process (second issue process) of the IC card 1a is executed by the issuer of the IC card 1a (step S610). That is, the issuer of the issuer executes a second issue process for writing detailed information to the IC card 1a.

In the second issue process of step S610, the process from step S611 to step S613 is the same as the process from step S211 to step S213 shown in FIG.
In the second issuance process in step S610, as shown in steps S611 to S613, the issuer device of the issuer transmits the STORE DATA command set in the first state to the IC card 1a to use, for example, Detailed information that differs for each person is stored in a predetermined area.

  Next, in the second issuance process in step S610, the issuer device of the issuer transmits, for example, “STORE DATA command (4)” set in the second state (step S614). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0004”, write data = blank (data length is “00h”, no write data) to the IC card 1a. In this case, the tag ID = “0004” is unnecessary data, and the write processing unit 51a executes a process of invalidating the area having the tag ID “0004” as the second process. That is, the write processing unit 51a changes the validation information corresponding to the area with the tag ID “0004” to “0” and invalidates the area with the tag ID “0004”.

  Next, the issuing device of the issuer transmits, for example, “STORE DATA command (5)” set in the second state (step S615). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0005”, write data = blank (data length is “00h”, no write data) to the IC card 1a. In this case, the tag ID = “0005” is unnecessary data, and the write processing unit 51a executes a process of invalidating the area with the tag ID “0005” as the second process. That is, the write processing unit 51a changes the validation information corresponding to the area with the tag ID “0005” to “0” and invalidates the area with the tag ID “0005”.

  Next, the issuing device of the issuer transmits, for example, “STORE DATA command (6)” set in the second state (step S616). That is, the issuing device of the issuer transmits a STORE DATA command set with tag ID = “0006”, write data = blank (data length is “00h”, no write data) to the IC card 1a. In this case, the tag ID = “0006” is unnecessary data, and the write processing unit 51a executes a process of invalidating the area with the tag ID “0006” as the second process. That is, the write processing unit 51a changes the validation information corresponding to the area with the tag ID “0006” to “0” and invalidates the area with the tag ID “0006”.

  As described above, in the second issue process of step S610, as shown in steps S614 to S616, the issuer device of the issuer transmits the STORE DATA command set to the second state to the IC card 1a. The temporary setting information (for example, unnecessary information) stored in the data area 82 in advance is invalidated.

As described above, in the IC card 1a according to the present embodiment, information is stored in advance in a predetermined area corresponding to the area identification information. As the second process, the write processing unit 51a executes a process of invalidating information stored in advance in a predetermined area.
Accordingly, when the IC card 1a according to the present embodiment uses information (for example, temporary setting information) stored in the data storage unit 80a as it is, information to be written by the external device 2 (for example, write data). Is not transmitted to the IC card 1a, and the time required for the issue (issuer issue process) can be shortened.

  Further, the IC card 1a according to the present embodiment can appropriately invalidate unnecessary information (for example, unnecessary temporary setting information) by the second process. Therefore, for example, the IC card 1a according to the present embodiment writes the same information to the IC card 1a, but the second IC card 1a does not write the information for some IC cards 1a. This process can be dealt with by appropriately disabling.

(Fourth embodiment)
Next, an IC card 1a according to a fourth embodiment will be described with reference to the drawings.
The IC card 1a of the present embodiment is a modification of the second and third embodiments, and the external view, hardware configuration, and functional configuration of the IC card 1a are the same as those of the second embodiment, and therefore the description thereof is omitted. Is omitted. In the IC card 1a of this embodiment, the processing of the write processing unit 51a is different from the second and third embodiments, and the processing of the write processing unit 51a of this embodiment will be described.

In this embodiment, information (for example, temporary setting information) is stored in advance in a predetermined area corresponding to the area identification information, and the predetermined area in which the temporary setting information is stored in advance is Before, it is in a valid state. That is, the activation information corresponding to the predetermined area of the management area 81a of the IC card 1a is “1” (valid state).
The write processing unit 51a of the present embodiment erases information (for example, temporary setting information) stored in advance in a predetermined area as the second process. The write processing unit 51a invalidates the validation information corresponding to a predetermined area of the management area 81a by setting it to “0”. In this case, as in the first to third embodiments, the IC card 1a does not need to receive write data from the external device 2.

Next, the operation of the IC card 1a according to the present embodiment will be described with reference to the drawings.
FIG. 18 is a flowchart showing an example of the operation of the write command of this embodiment.

In FIG. 18, the processing in step S701, step S702, and step S705 is the same as the processing in step S101, step S102, and step S105 shown in FIG.
In this embodiment, in step S702, the write processing unit 51a advances the process to step S703 when write data is included (in the first state) (step S702: YES). If the write data is not included (in the second state as shown in FIGS. 5 and 7 described above) (step S702: NO), the write processing unit 51a advances the process to step S704.

  In step S703, the write processing unit 51a stores write data in the designated area. That is, the write processing unit 51a stores the received write data in a predetermined area corresponding to the area identification information (for example, tag ID) as the first process. After the process of step S703, the write processing unit 51a advances the process to step S705.

  In step S704, the write processing unit 51a erases the data stored in the designated area. That is, the write processing unit 51a erases the write data stored in the designated predetermined area as the second process. Here, with reference to FIG. 19, a specific example of the second process when the write command is a STORE DATA command in the present embodiment will be described.

  FIG. 19 is a diagram illustrating an example of the operation of the write command according to the present embodiment. In this figure, before execution of the STORE DATA command, the area with the tag ID “0001” and the data length (length) “04” is the state ST5 in which the data “AAAAAAAAAh” is stored in advance. In the management area 81a, “1” is stored as the validation information D6.

In such a state ST5, when the STORE DATA command set to the second state is executed, the write processing unit 51a erases the data in the area with the tag ID “0001” as the second process. To leave it blank. As a result, after execution of the STORE DATA command, the area where the tag ID is “0001” and the data length (length) is “04” is erased and becomes blank ST6. In this state, when a read command in which “0001” is specified as the tag ID is received, the IC card 1a transmits data indicating blank as a response. Note that the write processing unit 51a may further invalidate the predetermined area by setting the validation information of the management area 81a corresponding to the designated area identification information to “0”.
In addition, after the processing in step S704, the write processing unit 51a advances the processing to step S705.

  The procedure for issuing the IC card 1a according to this embodiment is the same as that of the third embodiment shown in FIG.

As described above, in the IC card 1a according to the present embodiment, information is stored in advance in a predetermined area corresponding to the area identification information. As the second process, the write processing unit 51a executes a process of deleting information stored in advance in a predetermined area.
Thus, when the IC card 1a according to the present embodiment uses the information (for example, temporary setting information) stored in the data storage unit 80a as it is, the external device stores the information to be written (for example, write data). There is no need to transmit to the IC card 1a, and the time required for issuing (issuer issue process) can be shortened.
Further, the IC card 1a according to the present embodiment can appropriately erase unnecessary information (for example, unnecessary temporary setting information) by the second process. Therefore, for example, the IC card 1a according to the present embodiment writes the same information to the IC card 1a, but the second IC card 1a does not write the information for some IC cards 1a. This process can be dealt with by appropriately erasing.

(Fifth embodiment)
Next, an issue device and an IC card issue system for issuing the above-described IC card 1 (1a) will be described with reference to the drawings.
FIG. 20 is a block diagram illustrating a configuration example of the IC card issuing system 200 according to the present embodiment.
As shown in this figure, the IC card issuing system 200 includes an issuing device 20 and an IC card 1 (1a).
The issuing device 20 includes a communication unit 21, an issue information storage unit 22, and an issue control unit 23. The issuing device 20 is, for example, a device used by the issuer in the issuing process.

  The communication unit 21 communicates with the communication unit 4 of the IC card 1 (1a) via the contact unit 3 of the IC card 1 (1a). For example, the communication unit 21 transmits various commands such as a write request (write command) for storing information in a predetermined area of the IC card 1 (1a) to the IC card 1 (1a). Further, the communication unit 21 receives from the IC card 1 (1a) a response that is an execution result of processing according to various commands.

  The issuance information storage unit 22 stores issuance information to be written to the IC card 1 (1a) when issuing the IC card 1 (1a). The issue information includes at least area identification information and information related to information to be written in a predetermined area corresponding to the area identification information. Here, the information related to the information to be written in the predetermined area includes, for example, information for determining the presence / absence of the write data, that is, the first state and the second state of the write command. Note that the issuance information may be information indicating, in order, the APDU of each command transmitted to the IC card 1 (1a) in the issuance process.

The issue control unit 23 is, for example, a processor including a CPU and the like, and comprehensively controls the issue device 20. The issue control unit 23 includes an information acquisition unit 231 and an issue processing unit 232.
The information acquisition unit 231 (an example of an acquisition unit) acquires issue information from the issue information storage unit 22.

  The issuance processing unit 232 switches between the write command set to the first state and the write command set to the second state based on the issuance information acquired by the information acquisition unit 231, and the IC card 1 ( To 1a). For example, the issue processing unit 232 determines whether the command is a write command that is transmitted in the first state or a write command that is transmitted in the second state, based on information related to the write information included in the issue information. The issuance processing unit 232 switches between the write command set to the first state and the write command set to the second state based on the determination result, and the IC card 1 ( To 1a).

Next, the operation of the issuing device 20 of this embodiment will be described with reference to FIG.
FIG. 21 is a flowchart illustrating an example of the operation of the issuing device 20 according to the present embodiment.
In FIG. 21, the issuing device 20 first acquires issue information (step S801). That is, the information acquisition unit 231 of the issue control unit 23 acquires issue information from the issue information storage unit 22.

  Next, the issue processing unit 232 of the issue control unit 23 determines whether the command is a write command (step S802). In other words, the issue processing unit 232 determines whether or not the command to be transmitted next to the IC card 1 (1a) based on the acquired issue information is a write command. When the command to be transmitted next to the IC card 1 (1a) is a write command (step S802: YES), the issue processing unit 232 advances the processing to step S803. If the next command to be transmitted to the IC card 1 (1a) is not a write command (step S802: NO), the issue processing unit 232 advances the process to step S806.

  In step S803, the issue processing unit 232 determines whether there is write data. For example, the issue processing unit 232 determines whether there is write data based on the issue information. If there is write data (step S803: YES), the issuance processing unit 232 advances the process to step S804. If there is no write data (step S803: NO), the issuance processing unit 232 advances the process to step S805.

  In step S804, the issuance processing unit 232 transmits a write command in which write data is set to the IC card 1 (1a). That is, the issue processing unit 232 transmits the write command set to the first state to the IC card 1 (1a) via the communication unit 21. After the process of step S804, the issue processing unit 232 advances the process to step S807.

  In step S805, the issue processing unit 232 transmits a write command that does not set write data to the IC card 1 (1a). That is, the issuance processing unit 232 transmits the write command set to the second state to the IC card 1 (1a) via the communication unit 21. After the process of step S805, the issue processing unit 232 advances the process to step S807.

  In step S806, the issuance processing unit 232 transmits other commands (commands other than the write command) to the IC card 1 (1a) via the communication unit 21 according to the issuance information. After the processing in step S806, the issue processing unit 232 advances the processing to step S807.

  In step S807, the issue processing unit 232 determines whether a response has been received. That is, the issuance processing unit 232 determines whether a response is received from the IC card 1 (1a) via the communication unit 21. If the issuance processing unit 232 receives a response (step S807: YES), the issuance processing unit 232 advances the processing to step S808. If the response is not received (step S807: NO), the issue processing unit 232 returns the process to step S807.

  In step S808, the issue processing unit 232 determines whether or not the response is normally completed. If the response is a normal end (step S808: YES), the issuance processing unit 232 advances the process to step S809. If the response is not normally terminated (abnormal termination) (step S808: NO), the issue processing unit 232 advances the process to step S810.

  In step S809, the issue processing unit 232 determines whether the issue is finished. For example, the issue processing unit 232 determines whether or not the issue has ended based on the issue information. The issuance processing unit 232 terminates the process when the issuance is finished (step S809: YES). If the issue processing unit 232 does not end the issue (step S809: NO), the issue processing unit 232 returns the process to step S802.

  In the above-described example, the example in which the information acquisition unit 231 acquires the issuance information collectively in step S801 has been described. However, the information acquisition unit 231 may acquire the information for each command. In that case, the issue end determination process in step S809 may be executed after the process in step S801.

As described above, the issuing device 20 according to the present embodiment is an issuing device that issues the above-described IC card 1 (1a), and includes the information acquisition unit 231 and the issue processing unit 232.
