Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of creating a pattern file for accessing an IC card, and more particularly to a method of creating a pattern file used when writing individual personal information to each IC card.

[0002]

2. Description of the Related Art IC cards have been attracting attention as new information storage media replacing magnetic cards. Especially CPU
Since the IC card having a built-in card can ensure a high degree of security for the information stored inside, it is expected to be widely used in the field of handling important information.

At present, IC cards which are generally popular are accessed by a reader / writer device. In particular,
In an IC card with a built-in CPU, a CP in the reader / writer device and the IC card is inserted via an interface circuit.
U and U are connected by a signal transmission line, and information is exchanged between them via this signal transmission line. In this case, the information is transmitted from the reader / writer device to the IC card in the form of a command, and conversely, the information is transmitted from the IC card to the reader / writer device in the form of a response to the command. Based on the command given from the reader / writer device, the CPU in the IC card executes various processes such as resetting, writing to and reading from the built-in memory, and outputs the execution result to the reader / writer device side in the form of a response. Will be returned. For example, when a reset command is given from the reader / writer device side, the IC
After executing the reset process, the CPU on the card side returns a predetermined code indicating the execution of the reset process to the reader / writer device side as a response. Further, when a command to write predetermined data together with predetermined data is given as a command from the reader / writer device side, the CPU on the IC card side executes the process of writing the data given as the command in the internal memory, and then Information indicating whether the data has been written correctly or an error has occurred is returned to the reader / writer device as a response.

As described above, information is exchanged between the reader / writer device and the IC card by transmitting / receiving a command from the reader / writer device side to the IC card side and returning a response from the IC card side to the reader / writer device side. It is performed by alternately repeating processing and processing. The reader / writer device side can judge whether or not the previously given command is correctly executed based on the response returned from the IC card side by the reply process. In order to smoothly perform such access processing to the IC card, a pattern file is usually prepared on the reader / writer device side. A pattern file that is currently generally used is composed of a table in which commands and responses expected to be returned in response to the commands are alternately arranged. That is, a pattern file including a table in which commands and responses are alternately arranged, such as command, response, command, response, command, ... Is prepared, and the reader / writer device follows the order of the pattern files.
The command is transmitted, and the response actually returned in response to this is compared with the response in the pattern file.

[0005]

However, in the above-mentioned access method using the pattern file, a great deal of labor is required to prepare the pattern file when accessing a large number of IC cards. For example, when writing personal information such as an individual member number, name, address, telephone number, date of birth, etc. in the memory in each IC card to issue one IC card to each individual, It is necessary to prepare a pattern file for each individual. Therefore, for example, when performing the process of issuing IC cards for 1000 persons, it is necessary to prepare such pattern files for 1000 persons.
Further, the formats of the pattern files that can be used may differ depending on the reader / writer device used, and the work of preparing pattern files of such different formats becomes extremely inefficient. For example, when the reader / writer device A performs the issuing process for the first 500 persons and the other reader / writer device B performs the issuing process for the latter 500 persons, the pattern described in the format A for the first half 500 persons. A file must be prepared, and a pattern file described in the format B must be prepared for the latter 500 people.

It is therefore an object of the present invention to provide a pattern file creating method capable of efficiently creating a pattern file used for recording different information for each IC card.

[0007]

[Means for Solving the Problems]

(1) According to a first aspect of the present invention, a signal transmission path is formed between an IC card having a built-in CPU and a reader / writer device for accessing the IC card, and the signal transmission path is provided via this signal transmission path. Based on a pattern file in which commands and responses are arranged, the communication process and the reply process of transmitting a predetermined command from the reader / writer device to the IC card and returning a response corresponding to the command from the IC card to the reader / writer device are performed. By executing, IC
When accessing a card, in the method of creating a pattern file used for access, prepare a personal information file that contains multiple personal information in record units and partially import the data in the personal information file. Conversion for preparing a template pattern file in which a command including a capture instruction and a response thereto are described in a first format, and converting the first format into a second format that can be read by a reader / writer device. A table is prepared, and predetermined data in the personal information file is loaded into a predetermined portion of the template pattern file based on the import instruction, and the first format is converted into the second format based on the conversion table. By doing so, the pattern file for each individual described in the second format is created.

(2) According to a second aspect of the present invention, a signal transmission path is formed between an IC card having a built-in CPU and a reader / writer device for accessing the IC card,
A predetermined command is transmitted from the reader / writer device to the IC card via this signal transmission path, and a response according to the command is returned from the IC card to the reader / writer device.
In the method of creating the pattern file used for the access when the IC card is accessed by executing the communication processing and the reply processing based on the pattern file in which the command and the response are arranged, based on a predetermined rule. A data generating means for generating predetermined data by calculation is prepared, and a command including a fetch instruction for fetching the predetermined data generated by the data generating means and a response thereto are described in the first format. A shape pattern file is prepared, a conversion table for converting the first format into a second format that can be read by a reader / writer device is prepared, and a predetermined portion of the template pattern file is read based on an import instruction. The specified data generated by the data generation means is fetched, and based on the conversion table, the first By converting the format to a second format, in which so as to create a pattern file for each individual described by the second format.

(3) A third aspect of the present invention relates to the above-mentioned first aspect.
Alternatively, in the pattern file creating method according to the second aspect, after the predetermined data is fetched into the command or response based on the fetching instruction, an error check code for the command or response including the fetched data can be calculated. The obtained error check code is added to the command or response.

[0010]

[Operation] When personal information such as individual member number, name, address, telephone number, date of birth, etc. is written in each IC card, processing to issue one IC card to each individual The contents of the pattern file used for the issuing process of each IC card are different. However, the only difference is the personal information such as individual member number, name, address, telephone number, date of birth, etc., and most of the rest is common. In the pattern file creating method according to the present invention, a template pattern file is prepared for this common part. In this template pattern file, the capture instructions are described instead of the actual data for the individual personal information portions that are not common, and the portion where the capture instructions are described will be described later in the personal information file. Predetermined data in will be taken in. That is, the template pattern file is a pattern file in which a blank portion is provided at a place where individual personal information should be captured. If the personal information of the individual A is captured in this blank portion, a pattern file for the individual A can be created. If the personal information of the individual B is taken in, a pattern file for the individual B can be created. Therefore, a large number of different pattern files for individuals can be efficiently created.

The template pattern file according to the present invention can be described in a first format that does not depend on each reader / writer device. The pattern file in the first format uses a conversion table. Then, it is converted into a pattern file of the second format suitable for each reader / writer device. Therefore, at the stage of creating the template pattern file, it is not necessary to be aware of the individual reader / writer devices, and efficient work can be performed.

Further, data such as a membership number given to each individual as a serial number, which can be automatically generated by an operation based on a predetermined rule, is not provided as a personal information file, but is provided according to the predetermined rule. If a means for automatically generating by a calculation based on this is prepared, individual pattern files for recording different information can be efficiently created by loading the data generated by this means.

[0013]

The present invention will be described below with reference to illustrated embodiments. First, based on the block diagram shown in FIG. 1, a conventional general access processing procedure for an IC card having a built-in CPU will be described. Here, two IC cards 1
An example will be described in which 0 and 20 are simultaneously connected to the reader / writer device 30 and both IC cards 10 and 20 are appropriately accessed. For example, when issuing one IC card as a membership card to a large number of members, the IC card 10 to be issued and the IC card 2 that functions as a key card in the issuing business.
If 0 and 0 are connected to the reader / writer device 30 to perform issuing work, security can be improved. That is, the IC card 2 as a key card
Unless 0 is used, the issuing business cannot be performed. Therefore, if the IC card 20 is properly managed, it is possible to prevent the membership card (IC card 10) from being issued by an illegal method.

As shown in FIG. 1, a typical IC
The card 10 includes an I / O interface 11 and a CPU
12, ROM 13, RAM 14, and EEPROM 1
5 and are built in. I / O interface 11
Is a device having a function of exchanging information with the outside via a signal transmission path 31 formed between the reader / writer device 30. The signal transmission path 31 may be formed as an electrical wiring path or may be formed as an electromagnetically coupled space path. Reader / writer device 30
From the I / O interface 1 via the signal transmission line 31
The information given to 1 is transmitted to the CPU 12, and vice versa.
Information to be transmitted from the CPU 12 to the outside is given from the I / O interface 11 to the reader / writer device 30 via the signal transmission path 31. The reader / writer device 30 includes
A host computer 40 is connected, and the reader / writer device 30 performs access processing to the IC card 10 under the control of this host computer 40. Further, the IC card 20, just like the IC card 10, has an I / O interface 21, a CPU 22,
The ROM 23, the RAM 24, and the EEPROM 25 are provided and are connected to the reader / writer device 30 via the signal transmission path 32.

In the IC card 10, ROM 13, RA
Three types of memories, M14 and EEPROM 15, are prepared. The ROM 13 is a memory that stores a basic program for operating the CPU 12, and CP
The U12 will execute various arithmetic processes based on the program in the ROM 13. The RAM 14 is a memory used as a workspace in this arithmetic processing. Further, the EEPROM 15 is a memory mainly used for accumulating user data, which is the original function of the IC card 10, and the user data given from the reader / writer device 30 side is written in the EEPROM 15 by the CPU 12. When a predetermined read command is given from the reader / writer device 30 side, the CP
The U12 reads the user data in the EEPROM 15 and sends it back to the reader / writer device 30 side. IC
ROM 23, RAM 24, EEPROM in the card 20
Three types of memory, 25, are also used for similar purposes.

Information exchange between the IC cards 10 and 20 and the reader / writer device 30 is performed by a command C and a response R.
The format is as follows. That is, the reader / writer device 3
Information is transmitted from 0 to the IC cards 10 and 20 in the form of a command C, and conversely, information is transmitted from the IC card 10 and 20 to the reader / writer device 30 in the form of a response R to the command C. . That is,
Information exchange between the two is performed by the IC from the side of the reader / writer device 30.
Communication processing of command C to the card 10, 20 side and IC
The process of returning the response R from the card 10 or 20 side to the reader / writer device 30 side is alternately and repeatedly executed.

In order to smoothly perform such an access process to the IC card 10, a pattern file F as shown in FIG. 2 is usually prepared. The pattern file F is composed of a table in which a command C and a response R expected to be returned in response to the command C are alternately arranged. In the example of FIG. 2, the command C and the response R are alternately arranged, such as the command C1, the response R1, the command C2, the response R2, the command C3, and the response R3. Here, the command C1 is the command which should be given to the IC card side first, and the response R1 is the response expected to be returned from the IC card side when this command C1 is given as an outgoing message. Is. Similarly, the command C2 is the second command to be given to the IC card side, and the response R2 is the response expected to be returned from the IC card side when this command C2 is given as an outgoing message. Is.

A pattern file F as shown in FIG.
Is prepared in the host computer 40 and given to the reader / writer device 30 as necessary, the reader / writer device 30 can use the pattern file F.
Based on the above, it is possible to smoothly access the IC card. That is, first, the reader / writer device 30 performs an outgoing message process of sending the command C1 to the IC card side. I
Whether the command C1 should be sent to the C card 10 or 20 follows the instruction described in the pattern file F. For example, the command C1 for the IC card 10
, The CPU 12 in the IC card 10
After executing this command C1, a reply process of returning a predetermined response to the reader / writer device 30 is performed. Therefore, the reader / writer device 30 compares and collates this actually returned response with the response R1 in the pattern file F, and if there is no problem, performs the communication process of sending the next command C2 to the IC card 10. After executing this command C2, the CPU 12 performs a reply process of returning a predetermined response to the reader / writer device 30. Therefore, the reader / writer device 30 compares and collates this actually returned response with the response R2 in the pattern file F, and if there is no problem, performs the communication process of sending the next command C3 to the IC card 10. Thus, the reader / writer device 30
Using the commands / responses arranged in the pattern file F in order, it is possible to smoothly carry out outgoing and reply processing. If there is any problem as a result of the response collation, the same command will be sent again.

As described above, the access method using the pattern file F can reduce the load on the reader / writer device 30 and enable efficient access, but it is different for many IC cards. As described above, in the case of accessing the contents, the number of pattern files to be prepared increases, and a great amount of labor is required to prepare these pattern files. For example, consider an example in which an IC card is issued as a membership card. This membership card must record personal information such as the member's name, address, telephone number, and date of birth. In this case, in order to issue the IC card 10 as a membership card, these personal information are stored in EEPRO.
It is necessary to write in M15, and it is necessary to prepare the pattern files for the number of members.

Another problem at the stage of preparing the pattern file is that the format of the pattern file differs depending on the reader / writer device used. In general, the IC card is standardized to some extent according to the ISO standard, and the command C given to the IC card and the response R returned from the IC card have a predetermined format. There is. However, various reader / writer devices are provided by various manufacturers, and the same IC
Even when the card is accessed, the pattern file format required when using the reader / writer device A and the pattern file format required when using the reader / writer device B are generally different. Target. Therefore, when preparing a pattern file, I
It is necessary to consider which reader / writer device is used to access the C card, and the description must be made in a predetermined format.

Here, the procedure for creating this pattern file will be described by giving a more specific example. For example, consider a case where the reader / writer device to be used requests a command code format as shown in FIG. 3 and a response code format as shown in FIG. The command code shown in FIG. 3 is composed of three parts: a control part, a command part, and a BCC. Here, the part that is actually transmitted as the command C to the IC card side is the command part and the BCC (error check code).
It is a part composed of and. The control unit ,,,
This is a part that gives information for internal processing of the reader / writer device, and is not transmitted to the IC card side. In the example shown here, the command code is divided into eight types, and the respective formats are shown in a table. That is, normal commands 1, 2,
Eight types of reset commands 1 and 2, power-on reset commands 1 and 2, and built-in commands 1 and 2 are prepared. Here, the numbers 1 and 2 at the end of each command are numbers that specify the IC card to be accessed, and the number 1
Indicates that the IC card 10 is an access target, and the number 2 indicates that the IC card 20 is an access target.

The normal command is a general command for writing to and reading from the IC card, and a predetermined command code string (format is defined by the IC card standard) together with the BCC code in the IC card 10 or It is for transmitting to the IC card 20. "00" or "01" of the control unit is the normal command 1 (targeting the IC card 10) or the normal command 2
This is a part that specifies which of (the IC card 20 is a target). Further, the control unit is not used (indicated as “φ” in the table, and these 2 bytes are ignored), and the control unit uses the following command unit and BC.
The total number of bytes of C (command length) is shown.

The reset command and the power-on reset command are commands for giving a reset signal to the IC card. The former is a command for resetting the CPU when the IC card has already started up, and the latter is for the IC card. On the other hand, this is a command for supplying power and a clock to perform a start-up operation and reset the CPU. The control unit is a reset command,
The power-on reset command is given to the control unit, and the control unit determines that the target IC card is the IC card 1
0 (0000) or the IC card 20 (FFFF). Note that these commands do not send any code through the signal transmission lines 31 and 32 for normal data transmission, but rather through a reset signal or power supply line or clock line dedicated to reset signal or power supply. There is no data in the command part because it is for supplying power and clock. Therefore, the control unit indicating the command length is "00".

The built-in command is a special form of the above-mentioned normal command, in which a predetermined part of data in the response code string obtained as the previous response is embedded in the command code string, and this is incorporated in the IC card. For sending to. The difference in format from the normal command is that the control unit indicates that it is an embedded command, "10" (IC
Card 10) or "11" (IC card 20
Is the target), and the point where the embedded start position and length are specified in the control section. This built-in command will be described later based on an actual example.

On the other hand, the response code shown in FIG. 4 is composed of three parts, a control part, a response part, and a BCC. Here, the part that is expected to be actually returned as the response R from the IC card side is the part that is composed of the response part and the BCC (error check code). That is, basically,
The data actually returned as the response R from the IC card side is compared and collated with the "response part + BCC" part shown in FIG. The control unit ,,,
This is a part that provides information for internal processing of the reader / writer device. In the example shown here, the response code is divided into three types, and the respective formats are shown in a table.

The full check is to compare and collate the response R returned from the IC card over all digits. “08” of the control unit is a portion indicating that this response code is the response code of “all checks”. The control part is not used (indicated as "φ" in the table, these 2 bytes are ignored),
The control unit indicates the total number of bytes (response length) of the response unit and BCC that follow.

The partial check is to compare and collate only some digits of the response R returned from the IC card side. “0A” of the control unit is a part indicating that this response code is a “partial check” response code. The control unit indicates the check start position and the length, and the control unit indicates the total number of bytes (response length) of the response unit and BCC that follow. For example, if the check start position is "03" and the length is "02", only the 2nd byte from the 3rd byte from the beginning of the response code string is subject to the comparison and collation, and the other portions are ignored. It will be.

The partial storage is a process of storing a part of the digits of the response R returned from the IC card side. “1C” of the control unit is a portion indicating that this response code is a “partial storage” response code. The control unit indicates the storage start position and the length, and the control unit controls the response unit and the BC that follow.
It shows the total number of bytes of C (response length).
For example, if the storage start position is "03" and the length is "02", data of 2 bytes from the third byte from the beginning of the response code string is stored, and the stored data is At the stage, it is incorporated into the command code string by the above-mentioned embedded command and used.

Now, some concrete work is performed by using the reader / writer device 30 which requests the command code format as shown in FIG. 3 and the response code format as shown in FIG. Consider the case. For example, the IC card 10 is issued to the member "Yamada" as a membership card. Here, as a simple model, "Yamada" is stored in the EEPROM 15 of the IC card 10 as a membership card.
By writing the surname and the given confidential code,
The IC card 10 can be issued as a membership card.
Then, in order to ensure security, this predetermined secret code is the E code of the IC card 20 managed by a legitimate issuer.
This IC card 2 is recorded in the EPROM 25.
In order to read some data from 0, let's assume that you have to collate a given secret code.

In order to perform such membership card issuing processing, for example, four commands C1 to C1 as shown in FIG.
C4 should be executed. First, with command C1,
The data "Yamada" is written in the IC card 10. Next, the command C2 prepares to read from the IC card 20. Specifically, this is a process of collating a predetermined secret code. The confidential code read from the IC card 20 is read by the subsequent command C3, and finally, the confidential code read by the command C3 is written in the IC card 10 by the command C4. By this procedure,
The member ID issuance process for Mr. "Yamada" can be executed.

In order to perform the processing shown in FIG.
It is necessary to prepare a pattern file as shown in (1) and apply this from the host computer 40 to the reader / writer device 30. C1 to C4 in the left column in the pattern file of FIG. 6 are symbols conveniently attached to show the correspondence with the commands C1 to C4 shown in FIG. Also,
The rows labeled R1 to R4 are C1 to C, respectively.
The response corresponding to the command on the line with the reference numeral 4 is shown. The pattern file shown in FIG. 6 is an array of commands and responses conforming to the command code format shown in FIG. 3 and the response format shown in FIG.

The data in the column labeled "command section / response section + BCC" is a command portion that is actually transmitted from the reader / writer device to the IC card, or a response portion that is actually returned from the IC card to the reader / writer device. is there. In addition, the part marked "Yamada" is actually
A 4-byte Kanji code corresponding to this is entered, but in FIG. 6, it is shown as "Yamada" for convenience of explanation. This "command part / response part + BCC" part is a part whose format is determined based on the standard of the IC card such as ISO, and the total number of bytes (command length,
Response length) is shown in the control section. Further, the first byte of this portion indicates the object of transmission / reception.
That is, in the example shown here, the first byte is "0".
It is one of four types of "1", "10", "67", and "76", and "01" is a command transmitted from the reader / writer device 30 to the IC card 10, "1".
“0” is a response returned from the IC card 10 to the reader / writer device 30, “67” is a command transmitted from the reader / writer device 30 to the IC card 20, and “76” is I.
It means a response returned from the C card 20 to the reader / writer device 30, respectively. The second and subsequent bytes are codes specific to individual commands or responses, and the last 1 byte is a BCC error check code. The contents of each command and response will be briefly described below.

The command C1 is a normal command for the IC card 10, and the control section not used contains arbitrary data "FF FF". "Command section /
"02" in the second and third bytes of "Response part + BCC"
"03" is an instruction code for instructing to write the subsequent data "Yamada". The response R1 corresponding to this command C1 is a response of all checks, and the control unit which is not used still has arbitrary data “FF”.
"FF" is included. In this example, "10 02 0" described in "command part / response part + BCC"
All 5 bytes of data "00 03"
It is compared and collated with the response returned from the card 10. That is, when the command C1 (writing “Yamada”) is normally executed in the IC card 10,
Since the predetermined response "10 02 00 00 03" is to be returned, the response R1
By confirming the match as a result of comparison and collation with, it is possible to recognize that the command C1 has been normally executed.

The command C2 is a normal command for the IC card 20, and the control section not used contains arbitrary data "FF FF". "Command section /
"05th byte" of the "response part + BCC"
00 ”is an instruction code for instructing the read preparation from the IC card 20. The response R2 corresponding to the command C2 is a response of the partial check, and the control section describes information of the check start position “01” and the length “01”. Therefore, in this example, of the 4-byte data “76 FF 003” described in the “command part / response part + BCC”, only 1 byte from the first byte is the IC card 2
It is compared and collated with the actual response returned from 0. That is, it is only confirmed whether or not the first 1 byte is "76".

The command C3 is a normal command for the IC card 20, and the control section which is not used contains arbitrary data "FF FF". "Command section /
"01" in the 2nd to 4th bytes of "Response part + BCC"
“02 03” is an instruction code for instructing reading from a predetermined address in the IC card 20. By executing this command, the confidential code in the IC card 20 is read and returned as a response to the reader / writer device 20 side. The response R3 corresponding to this command C3 is a partial storage response,
The read confidential code is temporarily stored on the reader / writer device 20 side. That is, the control unit of the response R3 indicates that the storage start position is “03” and the length is “0”.
2 ”is described. In this example, "76 01 F" is added to the "command part / response part + BCC".
Although 5 bytes of data “F FF FF” are described, “FF FF” of the third byte and the fourth byte and “FF” of the fifth byte are all dummy data. When the command C3 is given to the IC card 20, this is "76 01 ??????
? 5 bytes of data in the format "(" ????? "in the 3rd and 4th bytes surrounded by the broken line in the figure,
The read confidential code is entered and the 5th byte "?
? , The IC card 20 is designed based on a standard such as ISO, and the response R3 is a response from the IC card 20. This is because it is compatible. After all, when the reader / writer device 30 receives the actual response to the command C3, it temporarily stores the data (secret code) of the third byte and the fourth byte.

The command C4 is an embedding command for the IC card 10, and the control unit instructs the embedding start position "0".
Information of "2" and length "02" is described. This is to embed the data stored in the previous partial storage response in the portion from the second byte of the “command part / response part + BCC” to the second byte, and send this to the IC card 10 as a write command. , An instruction code for instructing writing to a predetermined address in the IC card 10. In this example, "command part / response part +
The 4-byte data “01 FF FF FF” is described in “BCC”, but the second and third bytes “FF FF” and the fourth byte “FF” are described.
Are data as dummy, and in fact,
The data stored in the previous response is incorporated in the second to third bytes surrounded by the broken line, and the BCC including this embedded data is entered in the fourth byte. The response R4 corresponding to the command C4 is a response of all checks, and the control unit not used contains arbitrary data “FF FF”. In this example,
All 4-byte data “10 01 03D1” described in “command part / response part + BCC” is compared and collated with the response returned from the IC card 10. That is, when the command C4 (writing of confidential data) is normally executed in the IC card 10, a predetermined response of “10 01 03 D1” is to be returned, so comparison with the response R4 By confirming the match as a result of the collation, it is possible to recognize that the command C4 has been normally executed.

From the above description, when the work shown in FIG. 5 is performed by using the reader / writer device 30 requesting the formats shown in FIGS. 3 and 4, the pattern file shown in FIG. 6 is prepared. I know I need to. By the way, the work shown in FIG. 5 is a process of issuing a membership card for a member “Yamada”.
The same issuing process must be performed for members of 0 or several thousand. Moreover, in the above example,
Although only the surname of the member "Yamada" is written in the IC card, in reality, various personal information such as the member's name, address, telephone number, and date of birth must be written. Therefore, the actual pattern file becomes more complicated, and such pattern file is
The work of creating in units of 00 or several thousand people requires a great deal of labor. Further, since the pattern file created by labor in this way is described in the formats shown in FIGS. 3 and 4, it cannot be applied to a reader / writer device that requires a different format.

The present invention is for solving such a problem, and the main point thereof is to prepare in advance a template pattern file shown in FIG. 7 and a personal information file as shown in FIG. Based on these files, each pattern file can be efficiently generated. The personal information file of FIG. 8 is a file accommodating a plurality of personal information in record units. In this example, one record has a 4-byte “Mr.” field, a 4-byte “Name” field, and a 50-byte “Name” field. The address field is composed of three fields. In other words, 1
This means that personal information is prepared as one record.

On the other hand, the template pattern file shown in FIG. 7 describes the same processing contents as the pattern file shown in FIG. 6 in a format as a template.
R1, ... Corresponds to the command C1, response R1, ... Shown in the left column of the pattern file shown in FIG. In the format of the template pattern file shown in FIG. 7,
A format in which the "command part / response part + BCC" part corresponding to the data part actually transmitted to or received from the IC card or the data part actually returned from the IC card is sandwiched between the first delimiter and the second delimiter. Take In this example, the first delimiter takes either "&-S" or "% -N" and the second delimiter takes either "&" or "%". The data sandwiched between "&-S" and "&" is treated as a command, and the data sandwiched between "% -N" and "%" is treated as a response.

Regarding the "command part / response part + BCC" part, the template pattern file of FIG.
It is quite common with the pattern file of, but the template pattern file has features in detail. Hereinafter, this characteristic part will be described.

First, regarding the command C1, the data portion "Yamada" in the pattern file of FIG. 6 is changed to "DATA, 1, 1" in the template pattern file of FIG.
4 ”. Here, while the description "Yamada" is the unique data itself, "DAT"
The description "A, 1, 4" is a capture instruction for capturing a part of the personal information file shown in FIG. Specifically, the description “DATA, 1, 4” is a capture instruction indicating that the first byte of the first record of each record of the separately prepared personal information file is captured at this position. If this is applied to the first record of the personal information file shown in FIG. 8, the unique data "Yamada" will be captured in the description "DATA, 1, 4".

The description "BCC" following the description "DATA, 1, 4" is obtained after the data in the personal information file is taken in based on the acquisition instruction "DATA, 1, 4". Whole BCC including captured data
This is an instruction to obtain the error check code by calculation and add the obtained error check code to this position. After all, when the command C1 in the template pattern file of FIG. 7 is applied to the first record of the personal information file of FIG. 8, the same 8-byte command portion as the command C1 of the pattern file of FIG. 6 is obtained. Will be done. Not only that, but when it is applied to the second record of the personal information file in FIG. 8, another command section containing the data “Suzuki” instead of the data “Yamada” can be obtained. , The BCC error check code when the data "Suzuki" is fetched is added.

As described above, the pattern file shown in FIG. 6 is a unique pattern file that can be used as it is by the reader / writer device 30, whereas the template pattern file shown in FIG. 7 is a reader / writer as it is. Is not in a form that can be used with the device 30,
It is a pattern file as a so-called “template” that is premised on the acquisition of data from a personal information file.

In the response R2 in the template pattern file of FIG. 7, the description "XX XXXXX" is seen, but this indicates that the check is not performed for the 1 byte at the position described as "XX". It is a thing.
Also, the response R3 in the template pattern file
And the description "YY YY" is seen in the command C4. This is “YY” in the response 1
The byte indicates that the 1-byte data at this position is partially stored, and the 1-byte "YY" in the command indicates that the partially stored data is to be incorporated at this byte position. . The process of partial storage and incorporation corresponds to the process of partial storage and incorporation of 2-byte data enclosed by a broken line in FIG.

After all, if a predetermined conversion table describing the correspondence relationship between the format of the template pattern file of FIG. 7 and the format of the pattern file of FIG. 6 is prepared, the template pattern file of FIG. A pattern file as shown in FIG. 6 can be obtained by synthesizing the personal information file shown in FIG. For example, in the template pattern file, the data sandwiched between the delimiters "&-S" and "&" is converted into either the normal commands 1 or 2 or the built-in commands 1 or 2 shown in FIG. However, if the following conversion table is prepared, unique conversion is possible. (1) The first byte of data is "01" and "Y
Does not include "Y" → Normal command 1 (2) The first byte of data is "01" and "Y"
Include "Y"-> Embedded command 1 (3) The first byte of data is "67" and "Y"
Does not include "Y" → Normal command 2 (4) The first byte of data is "67" and "Y"
Y ”is included. → Embedded command 2 Here, the value of the control unit may be the one corresponding to each command based on the format of FIG. 3, and the value of the control unit is
For a normal command, an arbitrary value such as "FF" may be described, and for an embedded command, a predetermined value may be described based on the "YY" position. Further, the control unit may describe the value of the total length of the command part + BCC. Furthermore, "DA
When the capture instruction "TA, ..." Is included, predetermined data may be captured from the personal information file in that portion, as described above.

FIG. 9 is a block diagram showing a configuration for carrying out the method for creating an IC card access pattern file according to the present invention. For example, if it is necessary to perform the work shown in FIG. 5 for 1000 members,
To prepare in advance the template pattern file 41 as shown in FIG. 7 and the personal information file 42 as shown in FIG. 8, and to perform the above-mentioned unique conversion as the conversion table 43. If the table is prepared in advance, the host computer 40 can automatically create a pattern file as shown in FIG. 6 for 1000 persons based on these files and table. Since these 1000 pattern files are described in a format that can be directly handled by the reader / writer device 30, by giving these pattern files to the reader / writer device 30 one by one,
It is possible to perform a process of sequentially issuing membership cards for 0 persons.

Data that can be automatically generated based on a predetermined rule among the personal information does not need to be prepared in the personal information file 42. For example, 1
When issuing a membership card for 000 people, consider writing the membership number on the IC card in addition to the member name and address described in the above example. This membership number is No. 1 to N
o. When given as a serial number like 1000,
Alternatively, when it is given as a regular number, if an algorithm for generating a member number based on this predetermined rule is prepared in the host computer 40, the member number data will be stored in the personal information file 42. There is no need to prepare. Stationery pattern file 4
In the first command section, for example, a fetching instruction of a serial number such as "SERIAL" may be described, and each generated member number may be fetched based on this fetching instruction. Of course, in the host computer 40,
After the process of fetching the member number generated in this way is performed, the correct BC for the data including each member number
The C error check code is arithmetically generated and added.

Moreover, not only the personal information of each member,
Predetermined time information such as the date of issue of the membership card, the management number used to manage each membership card on the issuer side, the issuer code for identifying the worker who issued the issuer, etc. Any data that can be automatically generated by the calculation based on the rule of is generated in the host computer 40 as a template pattern file as in the above example of the membership number. Capturing processing is possible.

As described above, according to the pattern file creating method of the present invention, the following two merits can be obtained. The first merit is that a capture instruction is described in the template pattern file, and by this capture instruction, data in a separately prepared personal information file or a predetermined number such as a serial number generated based on a predetermined rule is specified. Since individual pattern files can be created by partially importing data, it is only necessary to describe a single template pattern file even when issuing membership cards for 1,000 people. Is. A second advantage is that the description of the template pattern file can be made in a unique and simple format, and can be done without considering the format required by each reader / writer device. As can be seen by comparing the template pattern file in FIG. 7 with the pattern file in FIG. 6, the complicated data string of the control unit in FIG. 6 has simple delimiters and “XX”, “YY” in FIG.
, The labor to describe a file can be significantly reduced.

Although the present invention has been described above based on the illustrated embodiment, the present invention is not limited to this embodiment and can be implemented in various other modes. Particularly, the concrete formats shown in FIGS. 3 and 4 and the format of the template pattern file shown in FIG. 7 are formats as a very simple model for convenience of explanation, Are typically defined in more complex formats. Of course, the implementation of the present invention is not limited to a specific format, and the present invention can be applied to any format.

[0051]

As described above, according to the pattern file creating method of the present invention, the pattern file having a predetermined format is created based on the template pattern file and the personal information file. It becomes possible to efficiently create a pattern file used to record different personal information for each. Also,
Since the automatically generated data is loaded into the template pattern file to create the pattern file in a predetermined format, it becomes possible to efficiently create each pattern file.
