(2-2) Electronic Check Issuance Request A process for requesting the bank to issue an electronic check will be described with reference to FIGS. 6 and 7. In this case, as shown in FIG.
User A uses mobile voting terminal 11 to bank center 1 of bank C
4 is called and the mobile voting terminal 11 and the bank center 14 are connected directly or via a communication network (mobile communication network or fixed communication network).

The user A operates the input unit 117 to select an electronic check issuance requesting icon from various icons displayed on the display unit 115. This choice is I
The C card control unit 118 is notified. The IC card control unit 118 passes the IC card insertion request to the screen control unit 116, and the screen control unit 116 causes the display unit 115 to display a message prompting the user to insert (insert) the IC card 31. According to this message, the user A inserts the IC card 31 (S101). The IC card control unit 118 prompts the user to input a password (personal identification number) via the screen control unit 116. This authentication is performed when the password is input from the input unit 117. After the authentication, information such as the requested electronic check amount (amount of money) and the account number is input from the input unit 117 (S102). These pieces of information are stored in the IC card control unit 118.
Is transferred to the IC card 31 (S103).

From the IC card control unit 118 to the IC card 3
The information transferred to 1 is received by the command receiving unit 201, the processing distributing unit 202 supplies the command to the data processing unit 203, and the information such as the electronic check amount is supplied to the data storing unit 204 and is stored therein. . Based on the transferred data, the data processing unit 2 of the IC card 31
03 performs an issuance request process according to a predetermined program (S104). In this issue request processing,
The data processing unit 203 uses an asymmetric encryption algorithm (for example, RSA is used in the CBC mode) from the identification information of the issuer and the request data (amount of electronic check requested) preset in the data storage unit 204. Generate an electronic signature (digital signature).

Subsequently, the data processing unit 203 is processed by the processing shown in FIG.
As shown in (A), it is composed of a command identification ID indicating an electronic check issuance request command, issuer identification information of the issuer A, request data, the generated electronic signature, and account information for specifying the account of A. An issuance request command (a command requesting the bank to issue an electronic check) is generated.
The command transmission unit 205 transmits this issuance request command to the IC card control unit 118 of the mobile voting terminal 11 (S
105). The mobile voting terminal 11 transmits the issuance request command returned from the IC card 31 to the bank center 14 via the communication processing unit 112 and the communication network 21 (S105).

The IC card 31 transmits an issuance request command to the mobile voting terminal 11, and the request data and the electronic signature are stored in the electronic check storage unit in the data storage unit 204 (FIG. 5A).
In the check information area (electronic check record), and an issuance request flag indicating that an electronic check issuance request is in progress is set in the corresponding flag area (S106).

The bank center 14 identifies an encryption key (public key) from the issuer identification information (representing A) included in the received issue request command, and uses this key to identify the issuer identification information and the request data. An electronic signature is generated, and the generated electronic signature is compared with the received electronic signature (S107). If the electronic signatures do not match, an error is assumed and error processing is performed. If they match, the account file 14 based on the account information
Search 1 and withdraw the requested amount from A's account,
The account file 141 is updated.

Next, an electronic signature of the requested data is generated,
In addition, a unique issue number is assigned to each electronic check, an electronic signature is generated based on the request data, electronic signature, and newly issued issue number, and issuer identification information (bank) is added, The check information shown in 8 (B) is generated. This check information constitutes the substance of the electronic check. By this processing, the bank C can guarantee the electronic check. Further, the issuance log is generated and stored in the log file 142 along with the generation of the electronic signature (S10).
8).

The bank center 14 newly generates an electronic signature from the check information and, as shown in FIG. 8C, generates an issue response command including a command identification ID, check information, and an electronic signature. The bank center 14 returns the generated issue response command to the mobile voting terminal 11 of A (S109). Further, the bank center 14 stores the transmitted issuance response command in the internal memory together with the transmission destination, and turns on the issuance response flag indicating that the issuance response is in progress. The issue response command transmitted to the mobile voting terminal 11 of A is received by the communication processing unit 112, and is transmitted via the IC card control unit 118.
It is sent to the C card 31.

The command receiving section 201 of the IC card 31
Receives this issue response command, and the process distribution unit 2
02 supplies the received command identification ID to the data processing unit 203, and sends the check information and the electronic signature to the data storage unit 2.
04. The data processing unit 203 determines from the supplied command identification ID that the received data is the issue response command, and enters the issue response process (S11).
0).

In this issuance response process, the data processing unit 203 identifies the public key from the issuer (bank) identification information, generates an electronic signature based on the check information, and compares it with the received electronic signature. If they do not match, error processing is performed as invalid information. If they match, an electronic signature is generated from the request data, electronic signature, issue number, etc. in the received check information and the public key of the principal (A), and the electronic signature after the issue number in the received check information is used. Compare. If they do not match, an error is generated as incorrect information.

If the electronic signatures match, the data storage unit 2
In the electronic check storage area 04 (FIG. 5 (A)), the check information in which the issuance request flag is turned on is searched, and the received content and the request data in the check information and the electronic signature match the received check. Overwrite the information and turn off the issue request flag.

When the issue response process (S110) is completed,
The IC card 31 generates an electronic signature from the issuer identification information indicating A and the electronic signature located at the end of the received issue response command. Then, as shown in FIG.
A delivery confirmation command including these pieces of information is generated and transmitted to the bank center 14 via the mobile voting terminal 11 and the communication network 21 (S111). The bank center 14 executes delivery confirmation processing in response to the delivery confirmation command (S11).
2).

First, the bank center 14 identifies the public key of A from the issuer identification information of A included in the received delivery confirmation command, and then issues the electronic signature of the issuer identification information and the "electronic signature of the issue response command". A signature is generated and compared to the electronic signature located at the end of the received acknowledgment command. If they match, the command is a valid delivery confirmation command from A.

Next, it is determined whether the "electronic signature of the issuance response command" in the received delivery confirmation command and the electronic signature of the issuance response command saved at the time of issuing the electronic check match. If they match, it is determined whether or not the destination of the issuance response command saved at the time of issuing the electronic check and the issuer identification information of the received delivery confirmation command match. If they match, it means that it is a delivery confirmation command from the issue request command issuer. The issue response flag is turned off. Also, these histories are saved in the log file 142.

When a plurality of issuance response commands are stored, each electronic signature of the issuance response command whose issuance response flag is ON is compared with the "electronic signature of the issuance response command" in the received delivery confirmation command. And determine what matches. Next, it is determined whether or not the destination of the issuance response command, which has been determined to match, and the issuer identification information of the received delivery confirmation command, are matched. If they match, the corresponding issuance response flag is turned off.

From the IC card 31 to the mobile voting terminal 1
The issuance information is transferred to 1 (S113), the information about the electronic check is displayed on the display unit 115 for confirmation, and finally the IC card 31 is ejected (S114).

In this way, the mobile terminal holder can obtain a check (electronic check) distributed on the network.

In the electronic check issuing process, if a problem such as disconnection of the line occurs, or if the issuing process is intentionally interrupted midway, the following flag states may occur. (A) Electronic check issuance request flag ON, issuance response flag OFF This situation occurs when the electronic check issuance request command has not arrived at the bank center 14. (B) Electronic check issuance request flag ON, issue response flag ON This situation occurs when the issue response command has not reached the IC card 31. (C) Electronic check issuance request flag is off, issuance response flag is on This situation occurs when the delivery confirmation command has not arrived at the bank center 14.

These cases can be dealt with as follows. In the case of (a), A can perform the process again by inquiring the bank center 14.
In the case of (b), A can perform the process again by making an inquiry to the bank center 14. Further, the bank center 14 can confirm the content of the request of A from the data held by itself. In the case of (c), the bank center 14 notifies the issuer of the electronic check request command and executes a process of deleting the corresponding electronic check (check information) in the IC card 31.

In this way, since the electronic check issuance processing is performed while communicating the electronic check issuance request command, the issuance response command, and the delivery confirmation command, it is possible to surely determine at which stage the trouble has occurred, You can take the procedure. Further, since the electronic signature based on the public key is used, security can be enhanced.

(2-3) Electronic Check Transfer Request The electronic check issued in the above process can be passed (transferred) to another person on the network. The transfer process will be described below. In this case, the electronic check transmitting side A and the electronic check receiving side B are connected as shown in FIG. In FIG. 9, the check is transferred between the two mobile voting terminals 11 connected by the signal line. However, one mobile voting terminal 11 is provided with two IC card R / W slots and one of the slots is used. The electronic check may be transferred from the IC card 31 to the IC card 41 in another slot,
The electronic check may be transferred between the IC cards by alternately inserting / ejecting the IC cards into / from one IC card R / W slot. Also, the connection line can be of any type.

Next, a processing procedure for transferring the electronic check from the A side to the B side will be described with reference to FIG.

A moves the IC card 31 to the mobile voting terminal 11
(S201), the transfer processing icon is selected from the plurality of icons displayed on the display unit 115. Next, the amount of electronic checks transferred from the mobile voting terminal 11, the connection destination (mobile voting terminal of B), the password, etc. are input (S202). The information input to the mobile voting terminal 11 is transferred to the IC card 31 (S203), and electronic check transfer request processing is performed (S204).

In the electronic check transfer request processing, the IC
The card 31 determines whether or not the input electronic check amount exists in the electronic check storage area, and if there is not enough, an error is generated (in the following description, in order to facilitate understanding, the operation of each unit in the IC card 31 will be described. The explanation is omitted). If there is an electronic check that can be transferred, an electronic signature is generated based on the check information using an asymmetric encryption algorithm (RSA, etc.), and as shown in FIG. 11A, a command identification ID, issuer identification information, A transfer request command including check information and an electronic signature is generated.

Subsequently, the IC card 31 transmits the generated transfer request command to the mobile voting terminal 11. The mobile voting terminal 11 transmits the transfer request command transmitted from the IC card 31 to the B mobile voting terminal 11 (S20).
5). Further, the IC card 31 sets (turns on) a transfer request flag indicating that a transfer is being requested in the flag area corresponding to the electronic check used for the transfer request in the electronic check storage area (S206).

On the other hand, B sends I to the mobile voting terminal 11 of his own.
The C card 41 is inserted (S207), and the icon for electronic check reception is selected from the input unit 117 (S20).
8). This selection information is transferred to the IC card 41 via the IC card control unit 118 (S209), and the IC card 41 enters the electronic check reception waiting state.

Upon receiving the transfer request command, the mobile voting terminal 11 of B transfers this to the IC card 41. I
The C card 41 specifies the public key from the issuer identification information in the received transfer request command, and uses this public key and the received check information to generate an electronic signature. The IC card 41 compares the received electronic signature with the generated electronic signature (S210). If both electronic signatures do not match,
An error occurs and error processing is performed. If they match, the information is valid from A.

Next, an electronic signature is generated from the request data, electronic signature, and issue number data in the check information using the public key specified from the issuer identification information (bank) in the check information of the received transfer request command. Then, compare it with the electronic signature added after the issue number. If the electronic signatures do not match, an electronic check issuer error occurs. If they match, it is determined that the electronic check is issued by a valid bank, and the check information is written in the check information area (electronic check record) of the electronic check storage area in the data storage unit 204 of the IC card 41 of B (S211). ). As a result, the electronic check from A is received. Furthermore, the flag during transfer response is set in the corresponding flag area, and the transmission destination of the electronic check is also saved.

When the IC card 41 writes the electronic check from A into the data storage unit 204, the IC card 41 generates an electronic signature based on the written check information, and as shown in FIG. 11B, shows a transfer response command. Command identification ID
Then, a transfer response command including the issuer identification information indicating the issuer B, the check information, and the electronic signature is generated (S212). The IC card 41 sends the generated transfer response command to the mobile voting terminal 11 of B and the mobile voting terminal 1 of A.
It is transferred to the IC card 31 via 1 (S213).

From the command identification ID, the IC card 31 determines that the received data is the transfer response command, and executes the transfer response process (S214). In this transfer response process, the IC card 31 identifies the public key of B from the issuer identification information, and based on the input check information,
An electronic signature is generated and compared with the received electronic signature.
If they do not match, an error is generated as incorrect information.
If they match, the transfer response command from B can be confirmed. Next, the electronic check in which the transfer request flag in the electronic check storage area in the data storage unit 204 is on is searched, and the electronic check that matches the received check information is deleted, and at the same time, the transfer request flag is turned off.

When the transfer response process (S214) is completed,
The IC card 31 generates an electronic signature from the issuer identification information indicating A and the electronic signature located at the end of the received transfer response command. Then, as shown in FIG. 11C, a delivery confirmation command including these pieces of information is generated,
It transmits to the IC card 41 via the mobile voting terminal 11 of A, the communication network 21, and the mobile voting terminal 11 of B (S215).
The IC card 41 executes the delivery confirmation process in response to the delivery confirmation command (S216).

First, the IC card 41 identifies the public key of A from the issuer identification information of A included in the received delivery confirmation command, and then the electronic identification of the issuer identification information and the "electronic signature of the transfer response command". A signature is generated and compared to the electronic signature located at the end of the received confirmation of receipt. If they match, the command is a valid delivery confirmation command from A. Then, an electronic signature is generated from the check information with the transfer response flag turned on, and the received "transfer response command electronic signature" is compared by comparing this with the received "transfer response command electronic signature". It is determined whether or not it is generated by itself. Both electronic signatures match,
That is, when it is determined that the received transfer response command is generated by itself, it is determined whether or not the destination of the transfer response command and the issuer identification information in the received delivery confirmation command match, and if they match. If it is normal, the corresponding transfer response flag is turned off. This completes the transfer process.

From the IC card 31 to the mobile voting terminal 1
The transfer information is transferred to 1 (S217), the information regarding the electronic check is displayed on the display unit 115 for confirmation, and finally the IC card 31 is ejected (S218). Further, the reception information is transferred from the IC card 41 to the mobile voting terminal 11 (S219), the information regarding the electronic check is displayed on the display unit 115 for confirmation, and finally the IC card is ejected (S220).

In this way, an electronic check of any amount can be transferred from any IC card to any other IC card.

In the electronic check transfer process, if a problem such as line disconnection occurs, or if the issuing process is intentionally interrupted midway, the following flag status may occur. (A) Transfer request flag on, transfer response flag off In this situation, the transfer request command from the IC card 31 is I.
It occurs when it has not reached the C card 41. (B) Transfer request flag ON, transfer response flag ON In this situation, the transfer response command from the IC card 41 is I.
It occurs when it does not reach the C card 31. (C) Transfer request flag off, transfer response flag on This situation occurs when the delivery confirmation command from the IC card 31 has not reached the IC card 41.

These cases can be dealt with as follows. In the cases of (a) and (b), A on the transfer request side asks the electronic check issuer (bank) to issue a new electronic check. In addition, the electronic check transferred earlier is invalidated. Further, the electronic check issuer (bank) requests the transfer destination B to perform processing for canceling (erasing) the electronic check (check information) in the IC card 41. The transfer destination B erases the corresponding electronic check when the corresponding electronic check is stored in the IC card 41. The electronic check issuer (bank) transfers to the transfer destination (B) based on the request from the transfer requester (A).
Electronic checks may be sent directly to. In case of (c),
The transfer destination (B) asks the electronic check issuer (bank) to issue a new electronic check.

In this way, since the electronic check is transferred while communicating the transfer request command, the transfer response command, and the delivery confirmation command, it is possible to surely determine at what stage the trouble has occurred, and to take necessary procedures. be able to. Further, it is possible to prevent the abuse of the electronic check, such as transmitting the same electronic check to a plurality of persons. Further, since the electronic signature based on the public key is used, security can be enhanced.

(2-4) Electronic Check Cashing Request The system configuration for requesting the bank for electronic check cashing is the same as in FIG. The operation in this case will be described with reference to FIG. First, A inserts the IC card 31 into the mobile voting terminal 11 and selects the icon requesting cash conversion on the screen (S301). The cash conversion requester A uses the mobile voting terminal 1
Electronic check amount (amount) to request the bank to redeem from 1,
The account information of A, the personal identification number, etc. are input (S302). The input data is transferred to the IC card 31 via the IC card control unit 118 (S303), and the IC card 31 executes the cashing request processing (S304).

In the cashing request processing, the IC card 31
Checks whether the input amount of electronic check exists in the electronic check storage area of the IC card 31, and if there is,
Decides to send the electronic check to the bank. Next, an electronic signature is generated from the electronic check to be transmitted.
The electronic signature is generated using an asymmetric encryption algorithm (for example, RSA) based on the check information to be transmitted. As shown in FIG. 13A, the IC card 31 has a command identification ID, issuer identification information of A, check information,
A cash conversion request command including the generated electronic signature and deposit destination account information is generated and transferred to the mobile voting terminal 11. The format of the check information is shown in FIG. 13B for reference (same as the format of FIG. 8B). The mobile voting terminal 11 transmits the cash conversion request command transferred from the IC card 31 to the bank center 14 (S
305).

The IC card 31 transfers the cash request command to the mobile voting terminal 11 and, at the same time, turns on the cash request flag indicating that the electronic check in the electronic check storage area is requesting cash (S306).

The bank center 14 specifies the public key from the issuer identification information of the received cash exchange request command, generates an electronic signature from the issuer identification information (A) and the check information, and checks the received cash exchange request command check information. Is compared with the electronic signature behind (S307). If both electronic signatures do not match, it is an error.

If they match, then the public key is specified from the issuer identification information (bank) in the check information, and the requested data,
The electronic signature and the electronic signature of the issue number are generated and compared with the electronic signature located next to the issue number (S307). If they match, it can be confirmed that the electronic check was issued by a legitimate bank. If they do not match, error processing is performed.

Next, based on the received account information in the exchange request command, the account A is searched in the account file 141, the amount requested for exchange is deposited in the account A, and the log file 142 is processed. The log is saved (S308). After the deposit processing, the bank center 14 generates an electronic signature from the check information subjected to the deposit processing. The bank center 14 is shown in FIG.
As shown in FIG. 3C, a cashing response command including a command identification ID indicating a cashing response command, issuer identification information (bank C), check information, and the generated electronic signature is generated, and the mobile voting terminal 11 of A is generated. (S309). Further, this cashing response command is saved together with the cashing response in-progress flag.

The cashing response command returned to the mobile voting terminal 11 of A is transferred to the IC card 31. The IC card 31 determines from the command identification ID that the received data is a cashing response command, and starts cashing response processing (S310). First, the public key is specified from the issuer identification information. Next, an electronic signature is generated based on the received check information and compared with the electronic signature in the received cash exchange response command. If they do not match, an error is generated as incorrect information. If they match, as a legitimate result, the electronic check storage area is searched, the electronic check with the cash request flag turned on is searched, the record that matches the received check information is deleted, and the cash request flag is turned off. To do.

After the cashing response process is completed, the IC card 31
An electronic signature is generated from the issuer identification information indicating A and the electronic signature located at the end of the received issue response command.
Then, as shown in FIG. 13D, a delivery confirmation command including these pieces of information is generated and transmitted to the bank center 14 via the mobile voting terminal 11 and the communication network 21 (S31).
1). The bank center 14 executes delivery confirmation processing in response to the delivery confirmation command (S312).

First, the bank center 14 identifies the public key of A from the issuer identification information of A included in the received delivery confirmation command, and then issues the electronic identification of the issuer identification information and the "electronic signature of the cashing response command". A signature is generated and compared to the electronic signature located at the end of the received acknowledgment command. If they match, the electronic signature of the cashing response command in the received arrival confirmation command is compared with the electronic signature of the saved cashing response command whose cashing response flag is on, and the matching one is identified. To do. If a match is determined, it is determined whether or not the destination of the cashing response command and the issuer identification information in the received delivery confirmation command match, and if they match, it is regarded as normal and the issue response flag is set. Turn off. In addition, these histories are stored in the log file 142.
Will be saved to.

Further, the IC card 31 transfers the cashing information to the mobile voting terminal 11 (S313). Mobile voting terminal 1
1 displays the information regarding the electronic check for confirmation, and further ejects the IC card 31 (S314).

In this way, the electronic check can be cashed as necessary and can be credited to the own account.

In the cashing process, if a problem such as disconnection of the line occurs, or if the issuing process is intentionally interrupted midway, the following flag states may occur. (A) Cash request flag ON, cash response flag OFF This situation occurs when the cash request command has not arrived at the bank center 14. (B) Cash request flag on, cash response flag on In this situation, the cash response command is issued from the bank center 14
It occurs when it does not reach the C card 31. (C) Cash conversion request flag OFF, cash conversion response flag ON This situation occurs when the delivery confirmation command has not arrived at the bank center 14.

These cases can be dealt with as follows. In the cases (a) and (b), A can perform the process again by inquiring the bank center 14. Alternatively, a new electronic check can be issued. In the case of (c), the processing ends without the bank center 14 receiving the delivery confirmation command, so the bank center 14 notifies the issuer of the cashing request command and the IC card 3
By checking the electronic check (check information) in 1, it is possible to maintain consistency (erasing or processing completion).

In this way, since the cashing process of the electronic check is performed while communicating the cashing request command, cashing response command, and delivery confirmation command, it is possible to surely determine at which stage the trouble has occurred and to take necessary procedures. Can be taken. Further, it is possible to prevent the abuse of the electronic check, such as transmitting the same electronic check to a plurality of persons. Further, since the electronic signature based on the public key is used, security can be enhanced.

(2-5) Electronic check exchange request Electronic checks can be exchanged for electronic checks of other amounts, as in the case of ordinary checks. The system configuration when requesting the bank to exchange electronic checks is the same as in FIG. The exchange is not limited to the bank. The operation at the time of electronic check exchange will be described with reference to FIG. First, the currency change requester A sends I to the mobile voting terminal 11.
Insert the C card 31 and select the icon for the exchange process on the screen (S401). The requester A uses the mobile voting terminal 11
Enter the electronic check amount (amount of money) required to exchange money from the bank, the exchange method, the personal identification number, etc. (S402).

As a method of exchanging money, for example, "Kuzusu Money Exchange" in which one electronic check worth 100 yen is replaced with 10 electronic checks worth 10 yen and check 1 equivalent to 10 yen
There are two ways to exchange money, which is “to combine” when you make one electronic check worth 100 yen.

The input data is transferred to the IC card 31 (S403), and the IC card 31 performs the exchange request process described below (S404). The IC card 31 searches the electronic check storage area to check whether the input electronic check amount exists in the IC card 31. If so, check the validity of the exchange method. If the electronic check amount to be exchanged does not exist in the IC card 31, or if the exchange method is not appropriate, error processing is performed. The electronic check amount to be exchanged exists in the IC card 31, and
If the exchange method is valid, it decides to send the exchange request command to the bank center 14.

In this case, first, an electronic signature is generated using an asymmetric encryption algorithm (for example, RSA) based on the data of the exchange method and the check information. The IC card 31 generates an exchange request command in the format shown in FIGS. 15A and 15B from the generated electronic signature, check information, etc., and transfers it to the mobile voting terminal 11. It should be noted that FIG. 15A shows a format when the electronic checks are broken, and FIG. 15B shows a format when the electronic checks are put together.

The mobile voting terminal 11 sends the exchange request command transferred from the IC card 31 to the bank center 14 (S405). The IC card 31 is the mobile voting terminal 11
When the exchange request command is transferred to, the exchange request flag indicating that the exchange is being requested is turned on in the flag area of the corresponding electronic check in the electronic check storage area (S406).

The bank center 14 identifies the public key from the issuer identification information (A) of the received exchange request command, and uses this public key based on the exchange method and the check information.
Generate an electronic signature. Further, the generated electronic signature is compared with the received electronic signature (S407). If both electronic signatures do not match, it is an error. If they match,
As shown in FIG. 15C, the public key is specified from the issuer identification information (bank) in the check information, the request data, the electronic signature, and the electronic signature of the issue number are generated, and the electronic key next to the issue number is generated. The signature is compared (S407). If they do not match, error processing is performed. If they match, it can be confirmed that the electronic check was issued by a legitimate bank. If there are multiple pieces of check information, all check information is checked in the same manner.

When the electronic signatures match, the bank center 1
4 confirms the input exchange method and prepares a new check (S408). If the check cannot be prepared by the specified exchange method, an error will occur. Next, an electronic signature is generated from the exchange method, the check information at the time of request, and the check information of the exchange result (S409).

Next, using the generated electronic signature, FIG.
5 (D) or (E) is generated and the exchange response command is generated and transmitted to the mobile voting terminal 11 (S41).
0). Further, the transmitted exchange response command and the transmission destination are stored in the internal storage device, and the exchange response in-progress flag is set. Further, the bank center 14 takes a log of currency exchange (S4).
11).

The exchange response command transmitted to the mobile voting terminal 11 of A is transferred to the IC card 31. From the command identification ID, the IC card 31 determines that the received data is the exchange response command, and enters the exchange response process (S412). In this exchange response process, the IC card 31 specifies the public key from the issuer identification information, generates an electronic signature based on the received check information, and compares it with the received electronic signature. If they do not match, an error is generated as incorrect information. If they match, the result is valid.
Next, the electronic check storage area is searched, and the electronic check whose exchange request flag is ON is searched. Next, whether or not the new check information is a valid electronic check is determined by determining the electronic signature in each check information.
If all the check information is correct, the record of the check information at the time of request is erased, the exchange request flag is turned off, and new check information obtained as a result of exchange is written.

When the exchange response process (S412) is completed,
The IC card 31 generates an electronic signature from the issuer identification information indicating A and the electronic signature located at the end of the received exchange response command. Then, as shown in FIG. 15F, a delivery confirmation command including these pieces of information is generated,
It transmits to the IC card 41 via the mobile voting terminal 11 of A, the communication network 21, and the mobile voting terminal 11 of B (S413).
The bank center 14 executes delivery confirmation processing in response to the delivery confirmation command (S414).

First, the bank center 14 identifies the public key of A from the issuer identification information of A included in the received delivery confirmation, and generates an electronic signature of the issuer identification information and the electronic signature of the exchange response command. And compares it with the electronic signature located at the end of the received delivery confirmation. If they match, the command is a valid delivery confirmation command from A. Then, an electronic signature is generated from the check information of the currency exchange response command in which the currency exchange response flag is turned on, and by comparing this with the received electronic signature of the currency exchange response command, the received It is determined whether or not the “electronic signature” is generated by itself. If both electronic signatures match, that is, if it is determined that the received exchange response command was generated by itself, whether the issuer identification information of the received delivery confirmation command and the destination of the exchange response command match or not. To determine. If they match, the corresponding exchange response flag is turned off and the saved exchange response command is erased. These histories are saved in the log file 142.

When the exchange response process (S412) is completed,
The IC card 31 is a mobile voting terminal 1 that provides information about currency exchange.
1 is transferred (S415). The mobile voting terminal 11 displays the exchange result, electronic check information, etc. on the display unit 115,
A confirms the exchange result and the like (S416). Next, IC
The card is ejected (S417). In this way, the electronic check can be exchanged arbitrarily.

In the electronic check exchange process, if a problem such as line disconnection occurs, or if the exchange process is intentionally interrupted midway, the following flag status may occur. (A) Exchange request flag ON, exchange response flag OFF This situation occurs when the exchange request command has not arrived at the bank center 14. (B) Exchange request flag ON, exchange response flag ON This situation occurs when the exchange response command has not arrived at the IC card 31. (C) Exchange request flag OFF, exchange response flag ON This situation occurs when the delivery confirmation command has not arrived at the bank center 14.

These cases can be dealt with as follows. In the case of (a), A can perform the process again by inquiring the bank center 14.
In the case of (b), A can perform the process again by making an inquiry to the bank center 14. Further, the bank center 14 can confirm the content of the request of A from the data held by itself. In the case of (c), the bank center 14 can notify the issuer of an electronic check request command, confirm the content of the electronic check in the IC card 31, and request to execute the delivery confirmation process again.

In this way, the electronic check exchange process is performed while communicating the exchange request command, exchange response command, and delivery confirmation command. Therefore, even if some trouble occurs, it is possible to determine at what stage the trouble occurred. And you can take the necessary procedures. Further, it is possible to prevent the electronic check for which a request for exchange is made from being sent to another bank and exchanging one electronic check many times. Further, since the electronic signature based on the public key is used, security can be enhanced.

(3) Obtain pre-race information (odds, etc.) by FM multiplex broadcasting. The voting center 12 transmits the odds information, race information, etc. to the FM broadcasting station 16 via the communication network 21.
Send to The FM broadcasting station 16 distributes the information from the voting center on the FM multiplex broadcasting in a data format as shown in FIGS. 16 (A) and 16 (B), for example. The mobile voting terminal 11 uses this FM multiplex broadcasting to the FM multiplex processing unit 1
Received via 13. The screen control unit 116 causes the display unit 115 to display the received information in the format shown in FIGS. 17A and 17B, for example.

(4) Obtain expected information from the information providing center. The forecast information is paid by electronic check. A
Makes a call to the information providing center 15 and obtains expected information in exchange for an electronic check. Information provision center 15
Has the same check processing function as the mobile voting terminal 11, receives the electronic check transfer request command described in (2-5), and in return for the received electronic check, predicts the race (starting schedule, Probability forecast, corner situation forecast, first and second forecast, etc.) are transmitted to the user. The information providing center 15 can cash the received electronic check by the above-mentioned cash processing.

(5) Voting is performed using an electronic check to obtain an electronic voting ticket. (5-1) Electronic Voting When the user requests the voting center 12 to vote along with the electronic check, the voting center 12 returns an electronic voting ticket to the user as proof of the completion of voting. An electronic voting ticket is valid for 60 days like a regular voting ticket. The electronic voting ticket will be invalid if it is removed as a result of the race. In addition, the electronic voting ticket that has been hit is paid to the IC card 31 by making an electronic check of a payout equivalent amount by making a payout request to the voting center 12. The paid electronic check can be deposited into a designated account by the above-described cash conversion process. It is also possible to use the paid electronic check for the next vote.

(5-2) Voting Request Next, the voting process will be described with reference to FIGS. 18 and 19. When making a voting request to the voting center 12 using an electronic check, as shown in FIG. 18, the mobile voting terminal 11 and the voting center 12 are connected via a communication network. Voting requester A inserts IC card 31 into mobile voting terminal 11 (S5
01), and operates the input unit 117 to select the voting request icon (S502).

Subsequently, the vote requester A inputs the electronic check amount (vote amount) for requesting a vote, the voting method, etc. into the input unit 117.
From (S503). For example, an electronic check amount equivalent to 500 yen, 4000 yen for 1-5, 300 for 2-5
Enter 0 yen. The input data is transferred to the IC card 31 (S504), and the IC card 31 executes voting request processing (S505). The IC card 31 first checks whether the input electronic check amount is stored in the electronic check storage area, and if it is stored, checks the validity of the voting method. Electronic check is stored,
If the voting method is appropriate, it decides to send the voting request command. In other cases, error handling is performed.

Next, an electronic signature is generated based on the voting data using an asymmetric encryption algorithm, for example, RSA, and voting method data is generated from the voting data and the electronic signature, as shown in FIG. 20 (B). . Next, an electronic signature is generated using an asymmetric cryptographic algorithm, for example, RSA based on the voting method data and the check information. Furthermore, the generated electronic signature is added to the check information to generate a voting request command in the format shown in FIG. 20 (A), and this is sent to the mobile voting terminal 11 (S5).
06). The mobile voting terminal 11 transmits the voting request command transferred from the IC card 31 to the voting center 12 (S506).

The IC card 31 stores the voting method in the voting information area of the electronic voting ticket storage area, turns on the voting request flag indicating that the voting is being requested in the flag area, and further sets the corresponding flag area in the electronic check storage area. The transfer request flag is turned on (S507).

The voting center 12 specifies the public key from the issuer identification information of the received voting request command, generates an electronic signature based on the voting method and the check information, and compares it with the received electronic signature. If the electronic signatures do not match, it is an error. If they match, similarly, it is determined whether or not the electronic signature generated from the voting data in the voting method (see FIG. 20B) and the electronic signature accompanying the voting data match. If they do not match, error processing is performed. further,
The public key is specified from the issuer identification information in the check information shown in FIG. 20C, the request data in the check information, the electronic signature, and the electronic signature of the issue number are generated, and the electronic signature located next to the issue number is generated. It is determined whether or not If they match, it can be confirmed that the valid vote request is made by valid vote data and valid electronic check (step S508).

Next, the voting center 12 determines whether the voting contents can be issued or not according to the voting data (S509). If the content of the vote is valid, the electronic signature of the voting method and the issue number is generated. Further, FIG.
As shown in (E), issuer identification information is added to create voting information. When the voting information is generated, the check information is saved, an electronic signature is generated based on the voting information and the check information, and a voting response command (substantial electronic voting ticket) shown in FIG. 20D is generated (S510). ). Then, this electronic voting ticket is transmitted to the mobile voting terminal 11 of A as a voting response command (S511). At this time, a voting response flag is set in the saved check information. It also saves the voting response command and sets the voting response flag. Further, a log of voting records is stored in the log file 122 (S512).

Upon receiving the voting response command, the mobile voting terminal 11 of A transfers the voting response command to the IC card 31. I
The C card 31 determines from the command identification ID that the received data is the voting response command, and executes the voting response process (S513). In this voting response process, I
The C card 31 identifies the public key from the issuer identification information, generates an electronic signature based on the check information, and compares it with the received electronic signature. If they do not match, an error is generated as incorrect information. If they match, the result is valid.

Next, the electronic check storage area is searched, and the electronic check whose transfer request flag is on is searched for.
It is determined whether the check information matches. If they match, it is checked whether the electronic signature of the voting information identified from the issuer identification number of the voting information is the same, and if they match, the electronic signature of the voting data identified from the identification number of the person is It is determined whether the electronic signature of the received voting data matches. If all match, the record in which the voting request flag is on in the electronic voting ticket storage area is searched, and the voting information is written in the matching voting information record. Also, the check information in which the transfer request flag is on and the check information matches is erased, and each transfer request flag is turned off.

The IC card 31 generates an electronic signature from the issuer identification information indicating A and the electronic signature located at the end of the received voting response command. Then, the delivery confirmation command shown in FIG. 15 (F) is generated from these pieces of information,
Voting center 12 via mobile voting terminal 11 and communication network 21
(S514). The voting center 12 executes delivery confirmation processing in response to the delivery confirmation command (S51).
5).

First, the voting center 12 identifies the public key of A from the issuer identification information of A included in the received delivery confirmation command, and makes an electronic signature of the issuer identification information and the electronic signature of the issue response command. Generated and compared with the electronic signature located at the end of the received acknowledgment command. If they match, as a valid delivery confirmation command from A,
Among the saved response commands, compare the electronic signatures for which the response flag is on with the "electronic signature for the exchange response command" in the received delivery confirmation command.
Identify a match. When it finds a match,
It is determined whether the delivery destination of the electronic voting ticket and the issuer identification information in the received delivery confirmation command match, and it is confirmed that the delivery confirmation command is from the vote request command issuer. When these are normal, the voting response flag attached to the corresponding electronic voting ticket and the corresponding check information is turned off. These histories are saved in the log file 142. This completes the electronic voting ticket issuing process.

On the other hand, after the completion of the voting response process, the IC card 3
1 transfers information indicating the end of processing to the mobile voting terminal 11 (S516). The mobile voting terminal 11 performs a display for confirming the voting content, electronic check information, etc. (S517),
Further, the IC card 31 is ejected (S518).

When a defect such as a line disconnection occurs in the voting process, or when the issuing process is intentionally interrupted midway, the following flag states may occur. (A) Voting request flag on, voting response flag off This situation occurs when the voting request command has not reached the voting center 12. (B) Voting request flag ON, voting response flag ON This situation occurs when the voting response command has not reached the IC card 31. (C) Voting Request Flag Off, Voting Response Flag On This situation occurs when the delivery confirmation command has not reached the voting center 12.

These cases can be dealt with as follows. In the case of (a), A can perform the process again by making an inquiry to the voting center 12.
In the case of (b), A can perform the process again by making an inquiry to the voting center 12. Further, the voting center 12 can confirm the content of the request of A from the data held by itself. In the case of (c), the voting center 12 notifies the issuer of the voting request command and executes the processing of erasing (reversing) the corresponding voting information in the IC card 31. Also, electronic checks etc. will be returned to A.

In this way, since the electronic voting ticket issuance processing is performed while communicating the voting request command, voting response command, and delivery confirmation command, even when a trouble occurs, it is possible to ascertain at what stage the trouble occurred. To
You can take the necessary procedures. Further, since the electronic signature based on the public key is used, security can be enhanced.

(6) Check the race situation in FM multiplex broadcasting. (6-1) When it is time to hold the race, the relay center 1
3 acquires the position information of the race (in the case of a boat race, the position and direction of each ship) via the camera 20, and transmits the acquired position information to the FM broadcasting station 16 via the communication network 21. FM
The broadcasting station 16 distributes the race situation as FM multiplex broadcasting. The mobile voting terminal 11 receives the FM multiplex broadcast via the FM multiplex processing unit 113, and displays the race status on the display unit 115 as shown in FIG. When a normal communication line is used, it is difficult to transmit a large amount of data such as image information because the transmission rate is low. Therefore, this electronic voting system employs the following race situation acquisition method and race situation reproduction method.

(6-2) Acquisition of Race Status The race status is obtained by detecting the position and direction of a moving object (a ship in the case of a boat race, a horse in the case of a horse race, a bicycle in the case of a bicycle race), and detecting this on the screen. This is done by simulating.
The position detecting method and the direction detecting method will be described below. (A) Position Detection Method First, as shown in FIG. 21 (A), the position of a moving object on a track or field is detected by a position detection device, and this is detected in a two-dimensional space as shown in FIG. 21 (B). It is represented by.

As a method of detecting the position of a moving object,
For example, there are the following methods. (I) Position detection method based on synchronization signal As shown in FIG.
A wireless synchronous light emitting device including the wireless receiver 53 is attached. When receiving the predetermined data (synchronous data), the wireless reception unit 53 causes the light emitting body 52 to emit light for a certain period.
On the other hand, the wireless synchronous position detection device shown in FIG.
While switching the synchronization data from the wireless transmission unit 54, a wireless signal is transmitted, and the light emitting position at that time is captured by the camera 56 via the optical bandpass filter 55 that transmits the light of the light emitting body 52. The image processing unit 57 processes the image acquired by the camera 56, and the position detection unit 58 detects the position of the moving object 51 on the two-dimensional coordinates from the image.

Synchronous data is sequentially switched and output, and the light emitter 52 of each moving object 51 is sequentially illuminated,
The position of each moving object 51 can be detected.

(Ii) Position Detection Method Using Optical Filters of Different Pass Bands As shown in FIG. 23 (A), a light emitting body 61 which emits light of different wavelengths to the moving object 51 at regular intervals or continuously. Attach. On the other hand, as shown in FIG. 23 (B), the position detecting device includes an optical bandpass filter 62 having a different pass band, and the moving object 5 is changed while changing the pass band.
The image of No. 1 is captured by the camera 63. The image processing unit 64
The image acquired by the camera 63 is obtained, and the position detection unit 65 detects the position of each moving object 51 in this image.

(B) Traveling direction detection function (i) Method for detecting the direction of a moving object The wireless synchronous light emitting device shown in FIG.
It is attached to the front and the rear of 1, and the front and rear light emitters emit light at slightly different timings by a synchronization signal.
The wireless synchronous position detecting device detects two corresponding light emitting positions, and as shown in FIG. 24A, calculates a vector from the coordinates of the rear issuing position to the coordinates of the front issuing position as the direction.

(Ii) Direction Detection Method by Simultaneous Light Emission As shown in FIG. 24 (B), the light emitting device is attached to three points of the moving object 51, and the same detecting device detects the positions of the three points, and the relationship of the three points is shown. From this, it is detected which direction the moving object 51 is facing at the moment the position is detected. For detection, for example, the positions of three points are previously detected with respect to the moving object 51.
A point indicating the head of the moving object 51 (hereinafter referred to as the head point), a point indicating the right side of the head of the moving object 51 (hereinafter referred to as the right wing point), and a point indicating the left side of the head of the moving object 51 (hereinafter referred to as the left wing point). It can be calculated by deciding beforehand. For example, as shown in FIG. 24B, when the light emitting device is installed at three points forming an isosceles triangle having the head of the moving object 51 as the vertex, after detecting the coordinates of the three light emitting bodies,
First, the two points with the closest distance between the two points are specified. next,
The coordinates of the midpoint of the two points are calculated. Then, the vector of the middle point and the remaining one point becomes the direction of the moving object.

(C) Data Transmission Method The communication network 21 receives position data representing the position of each moving object 51 and direction data representing the direction detected by such a method.
To the FM broadcast station 16 via the. The FM broadcast station 16 broadcasts these data by FM multiplex broadcasting. The transmission data consists of data indicating a position and data indicating a direction,
Data volume is small. Therefore, even when a communication line with a low transmission rate is used, transmission can be easily performed.

(D) Position Reproduction Function The mobile voting terminal 11 receives these data by the FM multiplex processing unit 113. Arithmetic processing unit 114 and screen control unit 1
Reference numeral 16 dynamically reproduces the movement of the moving object in real time based on the received position data and direction data. There are the following methods for reproduction.

(I) Reproduction method by virtual body The screen control unit 116 reproduces the position and orientation of a moving object according to the procedure shown in FIG. First, the screen control unit 116
The stadium is specified (S601), and an image of the specified stadium, which is a virtual background (virtual background), is displayed on the display unit 115 (S602). Next, the position data and the orientation data are received (S603), and the image of the moving object is drawn as shown in FIG. 26 according to the received position data and the orientation data (S604). Thereafter, each time the position data and the orientation data are received, the virtual body is drawn.

(Ii) Reproduction Method Using Real Image Object The target moving object and stationary object are transmitted or distributed to the mobile voting terminal 11 side in advance as actual image data. The mobile voting terminal 11 identifies the stadium (S601) and displays the photographed image on the display unit 115 (S602). Subsequently, the position data and the orientation data are received (S603), and the moving object is displayed from the received coordinates and the orientation data (S6).
04). Then, this process is repeated every time the coordinate and traveling direction data is received.

In this way, as shown in FIG. 27, the race (in the example, a boat race) is displayed on the display 115 of the mobile voting terminal 11 with a sense of realism. Therefore, the user
It is possible to know the status and results of the gate on the mobile voting terminal 11 without going to the stadium. In addition, since the position and orientation of a moving object are detected and the symbol is moved based on this information, it is appropriate even when the orientation of a moving object and its traveling direction do not always match, such as in a boat race. Various displays can be performed.

(7) If the winning ticket is a winning ticket, the voting center is requested to pay back and an electronic check is received as a dividend. As described above, A reports the race situation to the mobile voting terminal 1
1 can be confirmed on the display unit 115, and the voting result can be known from the race result. If the voting ticket is successful, A makes a refund request to the voting center 12. The voting center 12
The payout request is sent to the mobile voting terminal 11 by electronic check if it is valid. This electronic check is stored in the IC card 31.

The payback process will be described with reference to FIG. First, the refund requester A inserts the IC card 31 into the mobile voting terminal 11 (S701), and the voting center 12
The icon of the refund request is selected (S702).
Next, the voting information requesting a refund is selected from the voting information storage area (S703).

The input information is transferred to the IC card 31 (S704). The IC card 31 uses the transferred information to execute a refund request process (S705). In this refund request processing, the IC card 31 first checks the validity (deadline, etc.) of the selected voting information, and if there is validity, decides to transmit the voting information to the voting center 12. FIG. 29A shows the format of voting information. Then, an electronic signature is generated from the voting information to be transmitted. This electronic signature is generated using an asymmetric encryption algorithm, for example, RSA based on the voting information data. The generated electronic signature is added to the voting information, and is transferred to the mobile voting terminal 11 as a withdrawal request command for requesting a withdrawal to the voting center 12 together with the command identification ID and the issuer identification information. The format of the refund request command is shown in FIG. Also, FIG. 29B shows the format of the voting information included in the refund request command.

The mobile voting terminal 11 transfers the refund request command transmitted from the IC card 31 to the voting center 12. Further, the IC card 31 sets a refund request flag indicating that a refund request is being made in the corresponding flag area of the voting information storage area (S707).

The voting center 12 identifies the public key of A from the issuer identification information of the received refund request command, uses this public key to generate an electronic signature based on the voting information, and uses the received electronic signature. Compare. If both electronic signatures do not match, an error is determined and error processing is performed. On the other hand, if the two electronic signatures match, the public key is specified from the issuer identification information in the voting information, and the voting data, the electronic signature, and the electronic signature of the issue number are generated. Next, it is determined whether or not it matches the electronic signature located next to the issue number in the received voting information. If they match, it can be confirmed that a valid refund request has been made with valid voting information (S708).

Next, the voting center 12 confirms the voting information (S709), and confirms the validity of the voting information (expiration date, whether or not to win, etc.) from the race results and the like (S710).
If the contents are appropriate, the payout for the voting information is calculated based on the contents stored in the voting information file 121, and one or more corresponding electronic checks are prepared (S711).
Further, data regarding the withdrawal method in which the prepared electronic check amount is recorded is added, and an electronic signature of the withdrawal method, voting information, and check information is generated and added, and the withdrawal response command shown in FIG. 29C is generated. To do. The voting center 12
The generated refund response command is transferred to the mobile voting terminal 11 (S712). Further, the withdrawal response command is saved together with the withdrawal response flag and the withdrawal destination. Also, voting center 1
2, the log of the issued electronic check information, refund method, etc. is stored in the log file 122 (S71).
3).

The withdrawal response command transmitted to the mobile voting terminal 11 of A is transferred to the IC card 31. The IC card 31 determines from the command identification ID that the received data is the refund response command, and executes the refund response process (S714). In the refund response process, the IC card 3
1 specifies the public key from the issuer identification information, the refund method,
An electronic signature is generated based on the voting information and check information and compared with the received electronic signature. If they do not match, error information is processed as invalid information. On the other hand, if they match, the information is valid.

The IC memory 31 searches the voting information storage area, finds out the voting information for which the withdrawal request flag is ON, and determines whether it matches the received voting information. If they match, the public key is specified from the issuer identification information of the voting information, the electronic signature of the voting data is generated by this public key, and it is determined whether the generated electronic signature and the electronic signature in the voting information match. Determine whether. If they match, check the electronic signature in the check information. If the electronic signatures in all the electronic checks match, the voting information in the voting information storage area is erased, the refund request flag is turned off, and the check information is written in the electronic check storage area.

After the refund response process is completed, the IC card 31
An electronic signature is generated from the issuer identification information indicating A and the electronic signature located at the end of the received issue response command.
Then, a delivery confirmation command including these pieces of information is shown in FIG.
Mobile voting terminal 1 generated in the format shown in FIG.
1 to the voting center 12 via the communication network 21 (S
715). The voting center 12 executes delivery confirmation processing in response to the delivery confirmation command (S716).

First, the voting center 12 identifies the public key of A from the issuer identification information of A included in the received delivery confirmation command, and the issuer identification information and the electronic signature of the withdrawal response command are electronically specified. A signature is generated and compared to the electronic signature located at the end of the received acknowledgment command. If they match, as a valid delivery confirmation command from A, among the stored refund response commands with the issuance response flag turned on, the electronic signature and " The electronic signature of the refund response command ”is identified. Then, it is determined whether the issuer identification information in the received delivery confirmation command and the delivery destination of the refund response command match, and it is confirmed that the delivery confirmation command is from the issuer of the refund request command. When these are normal, the withdrawal response flag is turned off and the withdrawal response command is erased. Also, these histories are saved in the log file 122.

Further, the IC card 31 transfers information indicating the end of processing to the mobile voting terminal 11 (S717). The mobile voting terminal 11 performs a display for confirming the electronic check information and the like (S718), and then ejects the IC card 31 (S719).

In the above refund process, if a problem such as a line disconnection occurs, or if the refund process is intentionally interrupted midway, the following flag status may occur. (A) Withdrawal request flag ON, withdrawal response flag OFF This situation occurs when the withdrawal request command has not reached the voting center 12. (B) Withdrawal request flag ON, issue response flag ON This situation occurs when the withdrawal response command has not arrived at the IC card 31. (C) Withdrawal request flag OFF, withdrawal response flag ON This situation occurs when the delivery confirmation command has not arrived at the bank center 14.

These cases can be dealt with as follows. In the case of (a), A can perform the process again by making an inquiry to the voting center 12.
In the case of (b), A can perform the process again by making an inquiry to the voting center 12. Further, the voting center 12 can confirm the content of the request of A from the data held by itself. In the case of (c), the voting center 12 notifies the issuer of the refund request command abnormally, and the IC card 3
The delivery confirmation command can be retransmitted from 1.
