For this reason, a predetermined specific authentication process is applied to the terminal 31 of the terminal 31 to write / read data to / from the second EF area (EFID3) 27b.
C card control program and IC card 11 card O
It is necessary to carry out with S.

Further, a protection memory area 29 is also provided in the storage area of the EEPROM 25. The protection memory area 29 (hereinafter also referred to as the protection memory 29) is a secret special area that cannot be referred from the terminal 31, and is a protection for permitting or prohibiting the write once write area 26. Information is stored. The above-mentioned storage area protection function of setting the write-once area 26 to the rewritable state is performed using the protection information of the protection memory area 29. The write permission or prohibition control using the protection information is individually performed for each of the plurality of unit storage areas forming the once-write area 26.

FIG. 5 shows the relationship between the protection information stored in the protection memory 29 and the write once area 26.

Here, it is assumed that the storage size of the write once area 26 is 5 bytes. In this case, the protection information of the protection memory 29 has 5 bits (b1 to b1).
It consists of 5). The first bit b1 of the protection memory 29 is protection information corresponding to the first byte storage area # 1 of the once write area 26, where "0" indicates writable and "1" indicates unwritable. . Similarly, 2
From the bit b2 of the bit to the bit b5 of the fifth bit,
It is protection information corresponding to each of the second byte storage area # 2 to the fifth byte storage area # 5 of the once write area 26.

In the initial state, as shown in FIG. 5A, the protection information b1 to b5 in the protection memory 29 is stored.
Are all "0", and all the storage areas # 1 to # 5 of the write once area 26 are writable.

Then, when the advertising electronic information 28 is written in the storage areas # 2 to # 4 of the once-writing area 26, for example,
As shown in FIG. 5B, the values of the protection information b2 to b4 in the protection memory 29 are updated from "0" to "1", respectively. As a result, the storage areas # 2 to # 4 of the write once area 26 are set to be unwritable.

In this way, the write control is performed such that the advertisement electronic information 28 is written once in the writing area 26 and the area in which the advertisement electronic information 28 is written is set to be non-rewritable by using the protection information of the protection memory 29. By providing the function in the IC card 11, RO
Instead of using an inefficient method such as writing the electronic information for advertisement 28 in the read-only ROM using an M writer, etc., simply by issuing a write control signal to the IC card 11 by the terminal of the advertiser or the card issuing company, IC with the rewriting of the electronic information for advertising 28 prohibited
It becomes possible to easily write on the card 11. In other words, in the card issuing company, when the advertisement requester requests after the IC card 11 is manufactured, the designated advertising electronic information 28 is prohibited from being rewritten into the designated number of IC cards 11. It becomes possible to write it and issue it immediately. Also, the advertiser is
It is also possible to write the URL of the homepage of the user's homepage or the like on the C card 11 as the electronic electronic information 28 for advertisement on the IC card 11 and then distribute it to the customers who visit the store managed by the advertiser.

Furthermore, in the write control process using the protection information of the protection memory 29, since the once-write area 26 is divided into unit storage areas to control the permission or prohibition of data rewriting, the once-write area is controlled. The extra area in 26 can be used for writing unrewritable data even after the IC card 11 is distributed. Therefore, even after the IC card 11 is distributed to the user, the write once area 26 can be used for storing various protection target data. For example, the identification information necessary for receiving the specific service as described above may be written once in the writing area 26.

Next, with reference to FIG. 6, a description will be given of how the stored information in the IC card 11 changes during the process from the initial state to the distribution thereof.

In FIG. 6, it is assumed that the data storage size of the write once area 26 is 24 bytes. In this case, the protection information of the protection memory 29 consists of 24 bits.

As shown in FIG. 6A, in the initial state of the IC card 11, no data is written in any area, and the protection memory 29 has 24 bits.
The bit protection information is all "0". IC card 11
Before the issuance of the advertisement electronic information 28 is written in the writing area 26 once. FIG. 6B shows the case where the 16-byte advertising electronic information 28 is written once from the beginning of the writing area 26. In this case, of the 24-bit protection information in the protection memory 29, the first 1
The 6 bits are changed from "0" to "1". Note that, for example, it is not necessary to prohibit rewriting of the advertising electronic information and the like for a limited period of time, and thus it may be stored in the first EF area (EFID2) 27a in the free writing area 27.

After the IC card 11 is distributed, FIG.
As shown in (c), the user uses the terminal 31 to write the first EF area (EFID2) 2 in the free write area 27.
User data can be freely written in 7a.

Next, referring to FIG. 7, the read / write operation for the EEPROM 25 controlled by the CPU 21 of the IC card 11 will be described.

When the CPU 21 of the IC card 11 receives data from an external host device such as a terminal used by the user to whom the IC card 11 is distributed, a card issuing company or a terminal owned by an advertiser (step S111), Is an access command for the EEPROM 25 (step S112). EEPROM
In the case of an access command for 25, the CPU determines which area is accessed, and whether the access is a write or a read, according to the read / write information and directory path information included in the command.
It is determined by 21.

In the case of writing to the write once area 26, the CPU 21 first checks whether or not the address value designated by the parameter in the read / write command is correct (step S113). For example, when the designated address value exceeds the data storage size of the write once area 26, the address value is determined to be incorrect, and the CPU 21 notifies the external host device of the access request of the error. To be done. If the specified address value is correct, the CPU 21 executes the above-mentioned storage area protection function to permit or prohibit writing to the write target area in the one-time write area 26 specified by the address value. Therefore, it is determined whether the bit value in the protection memory 29 corresponding to the write target area is "0" or "1" (step S114).

When the bit value is "1",
It is determined that the writing target area is set to be unwritable, and the CPU 21 notifies the external host apparatus of the access request source of the error. On the other hand, when the bit value is "0", the write target area is determined to be the write-enabled area, and writing is enabled. In this case, the CPU 21 checks the value of the one-time flag included in the access command (step S115). Here, the one-time flag is a flag indicating whether or not the write target area is write-protected after writing the data. If the one-time flag is "1",
The CPU 21 executes the write control function to update the corresponding bit value in the protection memory 29 to "1" and write the data in the write target area (steps S116 and S117). As described above, when the one-time flag is “1”, the corresponding bit value in the protection memory 29 corresponding to each storage area in which data is written is changed from the value “0” indicating the write permission to the write prohibition. Is updated to a value “1” indicating On the other hand, when the one-time flag is "0", the CPU 21 writes the data in the write target area while keeping the corresponding bit value in the protection memory 29 at "0" (step S117).

As described above, when the data is written in the write area 26 once, whether or not the rewriting of the data is prohibited can be designated by the host device side. Therefore, for example, when a plurality of electronic information for advertisement 28 is written once in the writing area 26, the plurality of electronic information for advertisement 28 is selectively set in a non-rewritable state so that the electronic information for advertisement cannot be rewritten. It is also possible to write once in the writing area 26 in a state where the rewritable electronic information for advertisement is mixed.

On the other hand, if the access command is a write to the free write area 27, the CPU 21 first checks whether or not the address value designated by the parameter in the command is correct (step S11).
8). If the address value is incorrect, the CPU 21
Notifies an error to the external host device of the access request source. If the designated address value is correct, the CPU 21 executes a data write process to the free write area 27 in step S117. However,
The second EF area (EFID) for which the access right is set
3) In the case of writing to 27b, the collation process using a password or the like is performed with the external host device, and the writing is permitted only when the authentication is correctly performed.

Also, when the access command is a read request, the CPU 21 first checks whether the address value designated by the parameter in the command is correct (step S119). If the address value is not correct, the CPU 21 notifies the external host apparatus of the access request source of the error. When the designated address value is correct, the CPU 21 reads the corresponding data from the once write area 26 or free write area 27 designated by the address value,
It is sent to the host device. When the data is read from the once-write area 26, the electronic information for advertisement 28 is transmitted to the host device by the electronic information transmission processing function described above.

The IC card control program executed by the terminal 31 is used when the power of the terminal 31 is turned on or when the IC card 1 is used.
Since the read command requesting the reading of the identification information and the read command requesting the reading of the advertising electronic information 28 are issued when the IC card 11 is mounted and the terminal 31 is used, the terminal 31 is installed. Is the IC card 11
It becomes possible to start a specific service corresponding to
It is possible to prompt the terminal 31 to display the advertising information corresponding to the advertising electronic information 28. When data is read from the second EF area (EFID3) 27b to which the access right is set, a collation process using a password or the like is performed with an external host device, and the authentication is properly performed. Only the data read will be permitted.

FIG. 8 shows a screen transition of the host device at the time of writing data in the once write area 26.

The IC card control program executed by an external host device such as a terminal used by the user to whom the IC card 11 is distributed or a terminal owned by the card issuing company or the advertiser instructs the operator to write data. When is selected, first, a GUI screen as shown in FIG. 8A is displayed and the operator is inquired whether or not to save the data in the IC card 11. "Yes" on the screen in Figure 8 (a)
When the button is selected by the operator, the IC card control program displays a GUI screen as shown in FIG. 8B and asks the operator whether or not to protect the data from being rewritten.

When the operator selects the "Yes" button on the screen of FIG. 8B, the IC card control program writes once with the one-time flag set to "1". The write command to the area 26 is instructed to the IC card 11. As a result, the IC card 11 writes once in the write area 26 and sets the bit value of the corresponding protection memory to "1". Then, the IC card control program displays a screen as shown in FIG. 8C to notify the operator that the data was saved in a protected state.

On the other hand, when the "No" button on the screen of FIG. 8B is selected by the operator, the IC card control program is activated with the one-time flag set to "0". The IC card 11 is instructed to write a command to the write area 26. With this, IC card 1
In No. 1, the write area 26 is written once, and no operation is performed on the protection memory. And IC
The card control program displays a screen as shown in FIG. 8D to notify the operator that the data was saved without being protected.

Next, referring to the flowchart of FIG.
Terminal 31 used by the user to whom the IC card 11 is distributed
The procedure for displaying the advertisement information on will be described. Here, it is assumed that a personal computer, a mobile phone or the like is referred to as the terminal 31 instead of the IC card dedicated terminal.

When the power of the terminal 31 is turned on while the IC card 11 is attached, or when the IC card 11 is attached to the terminal 31 which is already turned on, the terminal 31 is previously stored in the terminal 31. The built-in IC card control program is automatically started. When the IC card control program detects that the IC card 11 is attached (step S201), it starts communication with the card OS in the IC card 11 and sends necessary information such as identification information to the IC card. 11, the read command for reading the data from the write area 26 once is instructed to the IC card 11, and the electronic information for advertisement 2
Try to get 8. Then, the electronic information for advertisement 28 is I
It is determined whether or not the electronic information for advertisement 28 is written in the once-writing area 26 depending on whether or not it is read from the C card 11 and transmitted to the terminal 31 (step S202). If the advertising electronic information 28 has not been transmitted from the IC card 11, that is, if the advertising electronic information 28 has not been written, the processing for displaying the advertising information ends at this point.

When the advertisement electronic information 28 is transmitted from the IC card 11, that is, when the advertisement electronic information 28 is written, the IC card control program stores the advertisement electronic information 28 in the terminal 31. It is determined whether or not there is an application program required to display the corresponding advertisement information (step S203). For example,
When the URL is stored as the electronic information for advertisement 28, an application such as a Web browser becomes an application program necessary for displaying the advertisement information. Further, when the image information in a predetermined file format is stored as the electronic information for advertisement 28, an image viewer program or the like capable of handling the image information in the file format is required to display the advertisement information. It becomes an application program.

If the application program necessary for displaying the advertisement information does not exist in the terminal 31, the processing for displaying the advertisement information is terminated at this point. On the other hand, when the application program necessary for displaying the advertisement information exists in the terminal 31,
The IC card control program passes the advertising electronic information 28 to the application program and activates the application program (step S204).
When the advertising electronic information 28 is the advertising information itself composed of image information or the like, the advertising information is displayed on the display device of the terminal 31 by the activated application program, but the advertising electronic information 28 is the URL. In the case of, the following processing is executed by the started application program.

That is, the started application program uses the URL to search the We on the Internet.
By accessing the server b, the advertisement page specified by the URL is acquired via the Internet (step S205). Then, the application program displays the acquired advertisement page on the display device of the terminal 31 (step S206).

Since the advertisement page normally includes URLs of other related homepages as link information, clicking the link information to another Web page on the displayed advertisement page causes another Web page to be clicked. You can also display the page. Further, some advertisement pages and the like have defined input fields for prompting the user to input personal information such as name, address, and mail address for the purpose of questionnaires. The personal information entered in the input field will be transmitted to the server. At this time, the personal information is written in the free writing area 27 of the IC card 11.
You can also save it in. By storing such personal information for questionnaire in the free writing area 27 of the IC card 11, when the same web page is accessed again, the personal information is read from the free writing area 27 and displayed on the web page. It becomes possible to easily input in the input field of.

The functions of the Web browser and the image viewer can be installed in the IC card control program.

Further, the electronic information for advertisement 28 is transmitted from the IC card 11 to the terminal 31 by the communication performed between the IC card 11 and the terminal 31, and the advertisement information is output.
The electronic information transmission process that prompts
Since the procedure may be performed between the S and the IC card control program of the terminal 31, the CPU 21 in the IC card 11 stores the advertising electronic information 28 without waiting for the read request of the IC card control program. The presence or absence of the electronic advertisement information 28 may be determined, and if stored, the advertising electronic information 28 may be transmitted to the terminal 31. Such a CPU
The electronic information transmission process by 21 may be executed first when the CPU 21 starts operating upon receiving power from the terminal 31.
