For example, your eldest son's birthday, your grandfather's name, your grandmother's name, your mother's maiden name, your hometown, the writer you like, your graduated elementary school, and so on. Randomly select the registered authentication data and ask the user for a question asking for the selected authentication data, for example, "What is your mother's maiden name?" be able to.

The outline of “loop settlement” of the electronic settlement system of the present invention will be described. “Loop payment” means the transaction processing of the transaction between the cashier terminal 10 and the user terminal 20 by transmitting information about the transaction so that the cashier terminal 10, the user terminal 20, and the payment server draw a loop. How to do.

In an electronic payment system, transactions are settled between a plurality of cashier terminals 10 and a plurality of user terminals 20, so the settlement server 30 requests a specific transaction for the transaction. It is necessary to identify the cashier terminal 10 to perform and the user terminal 20 to pay for the transaction, and perform the settlement process for the transaction between both.

Figure 13 is a diagram explaining the outline of “loop settlement”. (1) In the user terminal 20, the pattern code display section 354 displays the user ID converted into the pattern code. (2) In the cashier terminal 10, the pattern code reader 308 reads the pattern code, and acquires the user ID of the user terminal 20. (3) The cashier terminal 10 transmits the purchase information and the user ID acquired from the user terminal 20 to the settlement server 30. (4) The settlement server 30 uses a transaction identification number to identify the transaction. Issue a number by assigning it to a user ID. (5) The settlement server 30 sends the issued transaction identification number and accounting information to the user terminal 20. (6) In the user terminal 20, the message display section 350 displays the transaction information, and the pattern code display section 354 converts the user ID and the transaction identification number received from the settlement server 30. Display the pattern code. (7) In the cashier terminal 10, the pattern code reading section 308 reads the pattern code displayed by the pattern code display section 354, and acquires the transaction identification information and the user ID issued by the settlement server 30. I do. (8) The cashier terminal 10 connects to the settlement server 30 and transmits the transaction identification number and the user ID acquired from the user terminal 20 to the settlement server 30. (9) The settlement server 30 checks the transaction identification number received from the cashier terminal 10 with the transaction identification number stored in association with the user ID, and confirms whether they match. (10) When it is confirmed that the transaction identification numbers match, the payment server 30 performs the payment process. (11) The settlement server 30 transmits the settlement result to the user terminal 20.

In the "loop settlement", after the user confirms the accounting information, the cashier terminal 10 obtains the transaction identification number issued by the settlement server 30 in association with the user ID from the user terminal 20, and sets up the settlement server. If you do not send it to 30, payment will not be made. Therefore, fraudulent payment at the cashier terminal 10 can be prevented. For example, if a cashier at a retail store sends an arbitrary transaction identification number together with a user ID to the payment server 30 in an attempt to perform the payment processing fraudulently, the payment server 30 checks the transaction ID number to perform the processing. The discrepancy between the transaction identification numbers is confirmed, and the settlement process is stopped. In addition, the user terminal 20 used in the “loop settlement” need not always be connected to the settlement server 30. The user terminal 20 receives information from the settlement server 30 but does not need to transmit information to the settlement server 30. Therefore, “loop settlement” can be performed by a portable terminal having only one-way communication means such as a pager.

Hereinafter, the settlement process in the electronic payment system of the present embodiment will be described with reference to FIGS. 14 to 22. FIG. 14 is a flowchart of the settlement processing of the electronic settlement system of the present embodiment. Cashier terminal 10, user terminal 20, and payment server 3 0 is shown in a flow chart along a time line, and mutual information exchange between the cashier terminal 10, the user terminal 20, and the payment server 30 is shown by a horizontal arrow. FIGS. 15 to 20 are flowcharts showing details of the processing in FIG. FIG. 21 is a diagram illustrating an example of a screen of the cashier-side display unit 302 of the cashier terminal 10. FIG. 22 is a view for explaining an example of a screen of the display section 355 of the user terminal 20.

Hereinafter, unless otherwise specified, the exchange of information between the cashier terminal 10 and the settlement server 30 is performed via the communication line 18 and the information between the user terminal 20 and the settlement server 30. The exchange is performed via a wireless communication transmission line 28 and a communication line 38. The method of accessing the settlement server 30 from the cashier terminal 10 may be either a method of accessing by dialing up from a telephone line or a method of accessing a server gate via a dedicated line. The access method from the settlement server 30 to the user terminal 20 is performed by wireless telephone communication when the user terminal 20 is a pager or a mobile phone.

The settlement process will be described with reference to FIG. At a retail store, a user purchases a product and pays for the product at a cash register. The cashier receives a request for payment by electronic payment from the user, selects an electronic payment menu from the cashier terminal 10, and starts a loop payment (100). In the cashier terminal 10, the cashier-side display unit 302 displays the screen shown in FIG. In the user terminal 20, the processing start button 352 is pressed by the user, and the loop settlement is started (102). In the user terminal 20, the conversion section 358 converts the user ID into a pattern code, and the display section 355 displays the screen shown in FIG. 22 (a) (104). In the cashier terminal 10, the pattern code reading section 308 reads the pattern code displayed on the pattern code display section 354 (106). The cashier terminal 10 accesses the settlement server 30 and transmits the user ID and the cashier registration number read from the user terminal 20 to the settlement server 30 (108).

The settlement server 30 starts the connection with the cashier terminal 10 in response to the access from the cashier terminal 10 and inquires cashier terminal information based on the cashier registration number transmitted from the cashier terminal 10. (109). The processing of the cashier terminal information inquiry 109 will be described with reference to FIG. The settlement server 30 accesses the cashier database 50 (1090), and extracts cashier terminal information of the cashier terminal corresponding to the cashier registration number (1092). In the cashier terminal information, the retail store name, store name, authentication method, and the like are registered. The authentication method includes a visual authentication method and a password authentication method, and the cashier terminal information sets which authentication method to use. The settlement server 30 determines to use the authentication method set in the cashier terminal information (1094). In the following, a description will be given assuming that the use of the visual authentication method has been determined as the authentication method.

Returning to FIG. 14, the operation after the processing of the cashier terminal information inquiry 109 will be described. The settlement server 30 performs a user information inquiry 110 process.

The process of the user information inquiry 110 will be described with reference to FIG. The settlement server 30 accesses the user database 60 based on the user ID transmitted from the cashier terminal 10 (1100), and checks whether the user terminal 20 has been registered as a user (1102). ). If the user has not been registered, the message “Not registered” is sent to the user terminal 20 (1 104). The user terminal 20 displays the screen shown in FIG. 22 (b) indicating that the user has not been registered. The settlement server 30 stops the settlement between the cashier terminal 10 and the user terminal 20 (1106

) 0

If the user registration is confirmed, the user information is extracted from the user database 60 (1108). The user information contains information on the usage status of the user, and based on the information, checks whether there is any problem with the usage status of the user such as a credit card or a bank card (1110). If there is a problem with the usage status, a message “unavailable” is sent to the user terminal ₂₀ (1 1 1 2). The user terminal 20 displays the screen shown in FIG. The settlement server 30 stops the settlement between the cashier terminal 10 and the user terminal 20 (114).

If there is no problem in the usage status of the user, the settlement server 30 proceeds with the next process. Returning to FIG. The payment server 30 was determined at the cashier terminal information inquiry 109 Authentication is performed based on the authentication method. Here, the authentication processing will be described in the case where it is determined in the cashier terminal information inquiry 109 that the visual authentication is adopted as the authentication method. The settlement server 30 acquires the image of the face photograph of the user from the user database 60 in the user information inquiry 110, and distributes the image data of the face photograph to the cashier terminal 10 (1 1 2). The cashier terminal 10 receives the face image data of the user from the settlement server 30 and performs visual authentication (114).

The process of the visual authentication 114 will be described with reference to FIG. The cashier terminal 10 displays the face photograph image of the user (1140). FIG. 21B is a display example of the screen of the cashier terminal 10. The cashier compares the user with the face photo and confirms whether or not he / she is himself (1142). If it is doubtful or the purchase is expensive, the cashier selects the DOUB T button on the screen shown in FIG. 21 (b) and sends a DO UBT signal to the settlement server 30 (1144). If the cashier selects the OK button in FIG. 21 (b), the visual authentication processing 1 14 ends. When receiving the DOUBT signal from the cashier terminal 10, the settlement server 30 accesses the user database 60 based on the user ID in order to perform password authentication (1146), and from the user database 60, the password data required for password authentication. Is extracted (1148). The settlement server 30 initializes a variable n for storing the number of password requests to 0 (1 150). The settlement server 30 increments n by 1 (1 152), and transmits a password request message to the user terminal 20 and the cashier terminal 10 (1 154, 1 158). The user terminal 20 displays the screen shown in FIG. 22 (d) (1156), and the cashier terminal 10 displays the screen shown in FIG. 21 (c) (1160). The user inputs a password using the keyboard section 310 of the cashier terminal 10 (1162). The cashier terminal 10 transmits the password input by the user to the settlement server 30 (1164). The settlement server 30 receives the password transmitted by the cashier terminal 10 and checks whether the password is correct (1166).

If there is an error in the password transmitted from the cashier terminal 10, check whether the number of password requests n is greater than 2 (1 1 6 8). Return to the process and repeat the password request. If the password request count n is greater than 2, an authentication-inhibited message is transmitted to the user terminal 20 (1 170). The user terminal 20 displays the screen shown in FIG. 22 (f) notifying that the service cannot be used because authentication was not possible (1172). In addition, an authentication failure message is transmitted to the cashier terminal 10 (1 1 74). The cashier terminal 10 displays the screen shown in FIG. 21 (e) indicating that the password authentication has failed (1 176). The settlement server 30 sends the authentication failure message to the user terminal 20 and the cashier terminal 10, and then cancels the settlement between the cashier terminal 10 and the user terminal 20 (1178).

If the settlement server 30 confirms that the password is correct in the password verification 1 1 66 in the password authentication, a password authentication OK signal is transmitted to the user terminal 20 and the cashier terminal 10 (1 180, 1 1 84). . The user terminal 20 displays the screen of FIG. 22 (e) indicating that the password authentication has been successful (1182). The cashier terminal 10 displays the screen shown in FIG. 21D indicating that the password authentication has been successful (1186), and terminates the visual authentication process 132.

Returning to FIG. After the visual authentication processing 114 has been completed, the cashier terminal 10 transmits purchase price information including the total purchase price to the settlement server 30 (1 16). When receiving the purchase price information from the cashier terminal 10, the settlement server 30 assigns a transaction ID number to the user ID and issues it (1 17).

The transaction identification number is, for example, a sequence of numbers generated by random numbers. When the payment server 30 accesses the payment server 30 using the same transaction identification number at the same time as a plurality of cashier terminals 10 or the user terminals 20 at the same time, the payment server 30 associates the user ID with the transaction identification number. become unable. Therefore, a transaction identification number is assigned so that the same transaction identification number is not used more than once in a certain time. However, after a certain period of time, the same transaction identification number may be used again as the transaction identification number. By doing so, it is possible to maintain the uniqueness of the transaction identification number without increasing the transaction identification number.

Further, the settlement server 30 has a function of restricting the assignment of the transaction identification number so as not to issue the transaction identification number in the “access waiting” state described later. Therefore, it is possible to more reliably prevent the collision of the transaction identification numbers.

If there are many branches of a retail store, a transaction identification number with a small number of digits may cause a collision with a transaction identification number that generates a random number. In this case, the collision of the transaction identification numbers can be avoided by devising the range of random numbers so that the transaction identification numbers of the branches do not conflict with each other.

Thus, a transaction identification number is a number that identifies a transaction. It is a number with a small number of digits that can temporarily identify a transaction, instead of a number with a large number of digits, such as Transaction ID, which is uniquely defined for all transactions.

Returning to FIG. The settlement server 30 sends the issued transaction identification number and accounting information to the user terminal 20 (118). At this time, the settlement server 30 enters an “access waiting” state of waiting for the registration terminal 10 to access using the transaction identification number. The user terminal 20 receives the transaction identification number and the accounting information, and performs the process of accounting information confirmation 120.

The processing of the accounting information confirmation 120 will be described with reference to FIG. The message display section 350 displays the transaction information received from the settlement server 30 (122). The user checks the displayed accounting information (1204), and cancels the settlement if the accounting information is incorrect (1206). In this case, the user does not press the processing start button 352, and the pattern code display section 354 does not display the pattern code. If the user confirms that the accounting information is correct, the user presses the processing start button 352, and the pattern code display section 354 displays the pattern code.

Returning to FIG. When the user confirms the accounting information and presses the processing start button 352, the conversion unit 358 in the user terminal 20 transmits the user ID and the transaction identification number received from the settlement server 30 to the pattern code. And the screen shown in Fig. 22 (i) is displayed. The pattern code display section 354 displays the pattern code in which the user ID and the transaction identification number have been converted (122).

At the cashier terminal 10, the screen shown in FIG. 22 (f) is displayed, and the pattern code reading section 308 reads the pattern code displayed on the pattern code display section 354 (1 2 4) . The cashier terminal 10 accesses the payment server 30 and the user terminal The user ID and transaction identification number read from 20 are transmitted to the settlement server 30 (122). When the payment server 30 receives the user ID and the transaction identification number transmitted by the cashier terminal 10, it performs the transaction identification number collation 128.

The settlement server 30 is in an “access waiting” state of waiting for the cashier terminal 10 to access and transmit the transaction identification number. In the “waiting for access” state, the settlement server 30 checks the cashier terminal 10 and the user terminal 20 if there is a cashier terminal 10 that accesses the transaction ID number assigned to the user ID using the same transaction ID number. Settlement processing is performed between.

In the “access wait” state of the settlement server 30, a timeout is set, and the access wait from the cashier terminal 10 is limited to, for example, three minutes. If there is no access from the registrar terminal 10 even after the time limit expires, the settlement server 30 stops settlement and initializes. This timeout function is set to avoid troubles when the communication between the payment server 30 and the user terminal 20 is bad and the information is not normally transmitted from the payment server 30 to the user terminal 20. You.

In the settlement server 30, the storage unit 81 stores a message when the first communication unit 82 receives a user ID from the cashier terminal 10 and the processing unit 80 assigns a transaction ID number to the user ID and issues it. Stores the first time of. The second communication unit 84 transmits the transaction identification number to the user terminal 20. Thereafter, the second time when the user ID and the transaction identification number are received from the cashier terminal 10 is compared with the first time, and if the time does not exceed the set time of the timeout setting, the settlement processing is performed.

With reference to FIG. 19, the process of transaction identification number collation 1 28 will be described. In FIG. 19, the settlement server 30 is in the “waiting for access” state, has access from the cashier terminal 10, and checks whether the transaction identification number has been transmitted from the cashier terminal 10 (1 2 8 0) If there is no access, check whether the timeout time has elapsed (1 2 8 2), and if it has, if the transaction identification number sent from the cashier terminal 10 has been assigned, the transaction Cancel payment.

When the cashier terminal 10 transmits the transaction identification number, the transaction identification number set by the settlement server 30 by assigning it to the user ID and the transaction identification number transmitted from the cashier terminal 10 are set. If the numbers match, the transaction identification number matching error message is transmitted to the cashier terminal 10 and the user terminal 20 (1288). The user terminal 20 displays the screen shown in FIG. 22 (g) indicating the transaction identification number collation error.

Returning to FIG. When the transaction identification number matching process 128 is completed, the settlement server 30 performs a matching process 130 between the purchase amount and the available amount.

With reference to FIG. 20, the process 130 for matching the purchase amount with the available amount will be described. The settlement server 30 accesses the user database 60 based on the user ID (1300), extracts the usable amount of the user's credit card or bank card (1302), and transmits the usable amount and the cashier terminal 10 to the user. The purchase price is compared with the obtained purchase price (1304). If the purchase price does not exceed the available price, the matching is terminated. If the purchase amount exceeds the available amount, the user terminal 20 sends the message "Usage limit exceeded" (1 306), and stops the settlement process between the cashier terminal 10 and the user terminal 20. Yes (1308). At this time, a screen shown in FIG. 22H is displayed on the user terminal 20, indicating that the purchase price exceeds the available price.

Returning to FIG. 14, the operation after the processing 130 of comparing the purchase amount with the available amount will be described. The settlement server 30 accesses the user account database 70 and performs settlement processing for recording purchase information (1 32). When the settlement is completed, the settlement server 30 sends a settlement completion notice to the cashier terminal 10 (134), and sends a receipt to the user terminal 20 (136). The cashier terminal 10 displays the screen of FIG. 21 (g) indicating that the payment is completed (138). The user terminal 20 displays the screen of FIG. 22 (j) indicating that the settlement is completed (140).

In the above description of the payment process, when the payment server 30 sends the payment completion notification 146 to the cashier terminal 10, the payment server 30 transmits some attribute information regarding the user of the user terminal 20 that has paid for the transaction to the user. It may be extracted from the database 60 and transmitted to the registration terminal 10. The attribute information of the user sent to the cashier terminal 10 is, for example, information on the attribute of the user such as gender and age, and preferably does not include personal information such as a name, address, and a tail card number. Cashier terminal 10 Alternatively, the attribute information of the user who made the payment for the transaction may be acquired, and the transaction information may be associated with the attribute information of the user and accumulated in the sales history database 15 as a sales history. FIG. 23 is a diagram showing an example of a sales history information file stored in the sales history database 15. The date and time of sale and product identification number are stored in association with user attributes such as gender and age. As a result, the cashier terminal 10 can extract the purchase behavior of the user, such as the age group of the user who purchases a specific product, from the sales history information accumulated in the sales history database 15, and can perform marketing of the product. It can be used for

Further, the payment server 30 receives the total purchase price of the product from the cashier terminal 10, but receives detailed information on the purchased product, such as the name and unit price of the purchased product, and stores it in the user database 60. It may be recorded as the purchase history of the user.

The functions and operations of the payment processing of the electronic payment system according to the present embodiment are as described above. If a communication failure such as a communication interruption occurs in the above settlement exchange, information and temporary data for all processes are initialized and the processing is terminated. In the payment process described above, the payment server 30 performs the cashier terminal information inquiry 1 09, user information inquiry 1 110, transaction identification number issue 1 1 7, transaction identification number collation 1 2 8, purchase amount available The processing of the amount matching 130, the settlement processing 132, and the like are performed by the processing unit 80 and the database search unit 86 of the settlement server 30.

In addition, the payment server 30 is a data communication performed with the cashier terminal 10, a user ID transmission 108 from the cashier terminal 10, a user face photograph image transmission to the cashier terminal 10 1 12, and a cashier terminal 10. The first communication unit 82 of the settlement server 30 performs the processing of receiving the purchase amount information 1 16 and the settlement completion notification 1 34 from the settlement server 30.

In addition, the processing of the transaction information and transaction identification number transmission 1 18 to the user terminal 20 and the receipt notification 1 36 to the user terminal 20 which is the data communication performed by the settlement server 30 with the user terminal 20 is as follows. The second communication unit 84 of the settlement server 30 performs the processing.

In the electronic payment system according to the present embodiment, the cashier at the retail store can authenticate the user based on the photograph data of the user, and in the case of suspicion or expensive payment, can further request the user to input a password. Therefore, depending on the situation, the accuracy of authentication Can be raised. In addition, the user can easily and safely make a payment using a wireless communication device such as a pager or a portable terminal.

In the case of visual authentication, the settlement server 30 extracts the face photograph data of the user from the user database 60 and sends it to the cashier terminal 10 so that the cashier can authenticate whether the user is himself. In the case of password authentication, the payment server 30 extracts password information from the user database 60, sends a password request command to the user terminal 20 and prompts the user to input a password from the cashier terminal 10, and the payment server 30 Send to 0. The settlement server 30 checks the transmitted password against the password registered in the user database 60, and transmits the success or failure of the authentication to the cashier terminal 10.

In addition, for example, when visual authentication is not sufficient, the accuracy of authentication can be improved by performing a complex authentication such as combining other authentication methods such as password authentication.

In the above description, the payment server 30 checks the usage status of the electronic payment by the user by extracting the usage status file 604 stored in the user database 60. However, the number of times of electronic payment is stored, displayed on a bar code together with the user ID, read by the cashier terminal 10, transmitted to the payment server 30, and the payment server 30 is transmitted from the user terminal 20. The number of times of use may be compared with the settlement history stored in the use status file 604.

When the settlement is started, the user terminal 20 may issue an arbitrary code number for loop confirmation. The user terminal 20 displays the code number issued by the user terminal as a bar code, causes the cashier terminal 10 to read the code number, transmits the code number to the payment server 30, receives the code number from the payment server 30, and By confirming whether or not 0 is the same as the issued code number, it can be determined whether or not the settlement processing is normally performed.

As described above, according to the present embodiment, the settlement server 30 transmits the transaction identification number issued in association with the user ID to the user terminal 20. The user terminal 20 displays the transaction identification number as a bar code and causes the cashier terminal 10 to read it. The settlement server 30 transmits the issued transaction identification number, the transaction identification number received from the cashier terminal 10 and And settle the payment. If the cashier terminal 10 does not acquire the transaction identification number from the user terminal 20, the cashier terminal 10 will not perform the settlement processing. Therefore, since the cashier terminal 10 cannot proceed with the settlement process without obtaining the approval of the user terminal 20, unauthorized transaction can be prevented.

(Second embodiment)

An electronic payment system according to a second embodiment of the present invention will be described. In the first embodiment, the settlement server 30 searches the cashier terminal information stored in the cashier database 50, extracts the authentication method specified by the retail store or cashier terminal 10, and extracts the extracted authentication method. Authenticated the user based on the The second embodiment is characterized in that the user or the user terminal 20 can specify the authentication method, and determines the method of authenticating the user based on the user-specified authentication method and the cashier terminal-specified authentication method. This is different from the first embodiment. A description of the same configuration and operation as in the first embodiment will be omitted. FIG. 24 is a view for explaining an example of the authentication method stored in the authentication method field of the cashier terminal information 500. The authentication methods specified by the retail store or cashier terminal 10 include visual authentication and password authentication, such as no authentication, visual authentication or password authentication, visual authentication only, pass-only authentication, visual authentication and pass-pad authentication, etc. In addition to the type that specifies the authentication method using at least one, if the purchase amount is, for example, 10,000 yen or more, visual authentication and password authentication are performed.

In other cases, there is a type that changes the authentication method based on the purchase amount, such as performing visual authentication.

FIG. 25 is a diagram illustrating an example of an authentication method stored in the authentication method field of the user information 600. As the authentication method specified by the user or the user terminal 20, type U1 is without authentication specification. In this case, the authentication method specified by the cashier terminal 10 is used. Type U2 is for password authentication, and is used when the user always wants to perform password authentication. Type U3 is a visual authentication rejection, and is used when the user does not want the cashier to perform authentication using face photograph data. Type U4 is based on the purchase price, for example, if the purchase price is 5,000 yen or more, the password must be authenticated. It is a type that changes the authentication method.

FIG. 26 is a diagram illustrating an authentication method agreed between the cashier terminal 10 and the user terminal 20 based on the authentication method specified by the cashier terminal 10 and the authentication method specified by the user terminal 20. It is. If the user does not specify the authentication method, the authentication method specified by the cashier terminal 10 is actually performed. If the user does not specify the authentication method and the cashier terminal 10 specifies no authentication, no authentication is performed. This is used when proceeding with electronic payment without authentication, such as in the case of small payments. When the user does not specify an authentication method and the cashier terminal 10 specifies visual authentication or password authentication, at least one of visual authentication and password authentication is performed. For example, the person in charge of the cashier terminal 10 may select either visual authentication or password authentication, or may perform password authentication when it is difficult to authenticate a user by visual authentication. If the user does not specify an authentication method and the cashier terminal 10 specifies only visual authentication, only visual authentication is actually performed. Even if the user cannot be authenticated by visual authentication, password authentication is not performed. If the user does not specify an authentication method and the cashier terminal 10 specifies only password authentication, only password authentication is actually performed, and visual authentication is not performed. When the user does not specify the authentication method and the cashier terminal 10 specifies the visual authentication and the password authentication, both the visual authentication and the password authentication are actually performed. For example, even if the user can be authenticated by visual authentication, password authentication is further performed to increase the accuracy of the authentication.

Next, a case where the user specifies addition of password authentication will be described. By setting the addition of password authentication, for example, even if a mobile phone or a mobile terminal, which is an example of the user terminal 20, is dropped, abandoned, or stolen, another person steals the user terminal 20, It is possible to prevent unauthorized electronic payment. If the user specifies the addition of the password authentication and the cashier terminal 10 specifies the visual authentication or the password authentication, both the visual authentication and the password authentication are actually performed. Since visual authentication alone does not match the authentication accuracy specified by the user, even if the user can be authenticated by visual authentication, the passphrase is required to improve the authentication accuracy. Further authentication is performed. The user specifies the addition of password authentication and the cashier terminal

If 10 specifies only visual authentication, both visual authentication and password authentication are actually performed. The cashier terminal 10 specified only visual authentication, but the user requires not only visual authentication but also password authentication to perform highly accurate authentication, so password authentication is combined with visual authentication. And executed. As described above, when the user requests an authentication accuracy higher than the authentication accuracy requested by the cashier terminal 10, the authentication method with the higher authentication accuracy is actually performed. If the user specifies the addition of password authentication and the cashier terminal 10 specifies only password authentication, the authentication accuracy required between the cashier terminal 10 and the user matches, so only password authentication is actually performed. No visual authentication is performed. If the user specifies the addition of password authentication and the cashier terminal 10 specifies visual authentication and password authentication, the authentication accuracy required between the cashier terminal 10 and the user matches, and the visual authentication and password authentication Both are actually done.

Next, a case where the user has designated rejection of visual authentication will be described. By setting the visual authentication rejection, the user can display the face photograph data on the cashier terminal 10 and reject the authentication. When the user refuses visual authentication and the cashier terminal 10 specifies visual authentication or password authentication

However, since the user does not want visual authentication, only password authentication is actually performed. If the user refuses visual authentication and the cashier terminal 10 specifies only visual authentication, the authentication method requested between the cashier terminal 10 and the user does not match, so the authentication is rejected and the user is not authenticated. . Therefore, electronic payment is not performed. If the user refuses the visual authentication and the cashier terminal 10 specifies only the password authentication, the password authentication is actually performed and the visual authentication is not performed. If the user refuses visual authentication and the cashier terminal 10 specifies visual authentication and password authentication, the user rejects the visual authentication requested by the cashier terminal 10, so authentication is performed between the cashier terminal 10 and the user. Authentication is rejected, the user is not authenticated, and no electronic payment is made because no method agreement is formed.

FIG. 27 is a flowchart of the settlement processing of the electronic settlement system of the present embodiment. . FIGS. 28 to 31 are flowcharts showing details of the processing in FIG. The settlement process will be described with reference to FIG. The processing other than the processing of the user information inquiry 210 and the processing of the user authentication 220 is the same as the corresponding processing of the first embodiment shown in FIG.

The process of the user information inquiry 210 will be described with reference to FIG. The settlement server 30 accesses the user database 60 based on the user ID (2100), and searches for user information associated with the user ID. It is checked whether or not there is user information associated with the user ID in the user database 60, and it is checked whether or not the user terminal 20 has been registered as a user (2102). If the user has not been registered, the message “Not registered” is sent to the user terminal 20 (2104). A screen indicating that the user has not been registered is displayed on the user terminal 20, and the settlement server 30 stops the settlement between the cashier terminal 10 and the user terminal 20 (2106).

If the user registration is confirmed, the user information 6010 is extracted from the user database 60 (2108). As shown in FIG. 9, the user information 600 includes the attribute information of the user, the usage status of the user's electronic payment, the credit card or bank card number, the amount that can be settled, and the user or user terminal 20. The authentication method to be specified is stored. The settlement server 30 extracts the authentication method specified by the user or the user terminal 20 (2109). As shown in the example of FIG. 25, the contents set by the user or the user terminal 20 as the authentication method require a high authentication accuracy such as password authentication addition or a specific authentication method such as visual authentication rejection. They refuse or change the authentication method depending on the payment amount. Next, based on the information on the user's electronic payment usage stored in the usage status file 6030, it is checked whether there is any problem with the user's usage of credit card or bank card (2 1 10) . If there is a problem with the usage status, a message “unavailable” is sent to the user terminal 20 (2 1 1 2). A screen indicating that the terminal cannot be used is displayed on the user terminal 20, and the settlement server 30 stops the settlement between the cashier terminal 10 and the user terminal 20 (2114). No problem with user usage If so, the settlement server 30 proceeds with the next process.

The process of the user authentication 220 will be described with reference to FIG. The settlement server 30 determines the authentication method to be actually performed based on the authentication method specified by the cashier terminal 10 and the authentication method specified by the user terminal 20 (2200). As shown in an example in FIG. 26, the authentication methods specified by the cashier terminal 10 and the user terminal 20 are adjusted to determine the authentication method to be actually performed. If there is no authentication method that matches the authentication method specified by the cashier terminal 10 and the user terminal 20, respectively (2204), the settlement server 30 sends a message indicating authentication failure to the user terminal 20, and the settlement is stopped. . If there is a matching authentication method, the process proceeds to step 2206, where user authentication is performed based on the determined authentication method.

For example, in cashier terminal information inquiry 109, visual authentication or password authentication is extracted as an authentication method specified by cashier terminal 10, and in user information inquiry 210, password authentication is added as an authentication method specified by user terminal 20. The case where it is extracted will be described. In this case, since the user requests that password authentication be added to increase the authentication accuracy, the authentication method that can be agreed between the cashier and the user is visual authentication and pass-pass authentication. In other words, password authentication is performed after visual authentication, and authentication accuracy is ensured. FIG. 30 is a flowchart of the user authentication process 2206 in the case where password authentication is additionally performed after performing visual authentication. The settlement server 30 extracts the face photograph data of the user from the user database 60 (2208). The settlement server 30 distributes the face photograph image data to the cashier terminal 10 (2110). The cashier terminal 10 displays the face photograph image of the user received from the settlement server 30 (2212). The cashier compares the user with the photograph of the face and confirms whether or not the user is himself (2214). If it is doubtful, the cashier terminal 10 displays on the screen that authentication is not possible according to the instruction of the cashier (2216). The cashier terminal 10 sends an unauthenticated message to the settlement server 30 (2218). The settlement server 30 sends an unauthenticated message to the user terminal 20 (2224). The user terminal 20 displays on the screen that authentication is not possible (2226). Your identity is verified by your face photo In this case, the cashier terminal 10 transmits a signal indicating that the visual authentication has been successful to the settlement server 30 in accordance with the instruction of the cashier (2220). At this time, the cashier terminal 10 displays a screen indicating that password authentication is being performed. The settlement server 30 receives a signal indicating visual authentication success from the cashier terminal 10 and performs password authentication (2 2 2 2). FIG. 31 is a flowchart of the process of password authentication 2 222. The password authentication processing of step 1146 and subsequent steps is the same as the processing of the same reference numerals in the first embodiment shown in FIG.

Another example of user authentication 220 based on multi-authentication will be described. If the cashier terminal 10 specifies visual authentication or password authentication and the user terminal 20 specifies rejection of visual authentication, the only authentication method actually performed is password authentication. In this case, the settlement server 30 notifies the cashier terminal 10 that the password authentication is performed instead of the user refusing the visual authentication. The cashier terminal 10 displays on the screen that password authentication is to be performed instead of visual authentication by the user. Hereinafter, the same password authentication 2 222 2 processing as in FIG. 31 is performed.

Another example of user authentication 220 based on multi-authentication will be further described. This is the case where the cashier terminal 10 or the user terminal 20 specifies to change the authentication method based on the purchase price. As an example, consider a case where an authentication method is specified in which visual authentication and password authentication are performed when the purchase price is equal to or more than the allowable amount, and when the purchase price is equal to or less than the allowable amount, only visual authentication is performed. If both the cashier terminal 10 and the user terminal 20 specify that the authentication method should be changed depending on whether the purchase amount exceeds the allowable amount, the allowable amount specified by the cashier terminal 10 and the user terminal 20 The authentication method may be switched using the smaller amount as the allowable amount. The settlement server 30 determines whether or not the purchase amount of the user exceeds the allowable amount. If the purchase amount exceeds the allowable amount, the payment server 30 performs the same user authentication process 2206 as in FIG. If the permissible amount is not exceeded, the ability to perform only visual authentication is performed. If the visual authentication is successful, as in the processing of visual authentication 114 in the first embodiment shown in FIG. 17, password authentication is performed. Proceed without payment, and depending on the visual authentication, the user If it cannot be confirmed whether there is, password authentication is further performed.

In the electronic payment system of the present embodiment, both the cashier terminal 10 and the user terminal 20 specify an authentication method ^, and determine an authentication method that can be agreed between the retailer or cashier and the user. The user can be authenticated. Therefore, it is possible to adjust the authentication method and authentication accuracy required by the user and the authentication method and authentication accuracy required by cashiers and retailers. Also, the authentication method can be changed depending on the purchase price.

Therefore, there is an advantage that the user does not have to worry about the personal information being known to the merchandise seller and the privacy is protected.

(Fourth embodiment)

An electronic payment system according to a fourth embodiment of the present invention will be described. In the loop settlement in the first embodiment, the settlement server 30 determines the transaction identification number with the user terminal 20. Instead, in the present embodiment, the settlement server 30 The transaction identification number is determined with the cashier terminal 10. In this point, the present embodiment is different from the first embodiment. The configuration and operation of the payment server 30, cashier terminal 10, and user terminal 30 in the electronic payment system are the same as those of the payment server 30, register terminal 10, and user terminal 20 in the first embodiment. Since the operation is the same as the operation, the description is omitted.

The settlement process in the electronic settlement system according to the present embodiment will be described with reference to FIG. The cashier receives a request for payment by electronic payment from the user. When the cashier selects the electronic payment menu from the cashier terminal 10, loop payment is started (800). Next, the cashier terminal 10 notifies the settlement server 30 that loop settlement is to be performed (820). At this time, purchase information indicating the cashier registration number of the cashier terminal 10 and the amount of money purchased by the user are further transmitted. The settlement server 30 starts connection with the cashier terminal 10 in response to the access from the cashier terminal 10 and inquires cashier terminal information based on the cashier registration number transmitted from the cashier terminal 10. (804). The payment server 30 stores the transaction identification information in the cashier registration number received from the cashier terminal 10. (806). The settlement server 30 transmits the issued transaction identification number to the cashier terminal 10 (808). The cashier terminal 10 displays the received transaction identification number and cashier registration number on the cashier-side display unit 302 (810). The user of the user terminal 20 inputs the transaction number and the registration number displayed on the cashier display unit 302 of the cashier terminal 10 into the user terminal 20 (811). The user terminal 20 transmits the input transaction identification number, cashier registration number, and user ID to the settlement server 30 (8 12).

When the payment server 30 receives the transaction identification number from the user terminal 20, the payment server 30 refers to the transaction identification number (814). Next, the payment server 30 refers to the user information based on the received user ID ( 816) Then, based on the queried user information, information for requesting a password corresponding to the user ID is transmitted to the cashier terminal 10 (818). At this time, the cashier terminal 10 displays the password request on the cashier-side display unit 802 (819). The user inputs the password to the user terminal 10 according to this display.

The user terminal 10 transmits the input password to the settlement server 30 (820). The settlement server 30 receives the password requested from the cashier terminal 10 from the user terminal 20. Thereby, the settlement server 30 can authenticate the user.

The operations of the cashier terminal 10, the user terminal 20, and the settlement server 30 in the password request transmission step (8 18) and the password transmission step (820) in the figure are described in FIGS. This is the same as the operation after the user database access stage (1146) in the visual authentication stage (114) described using Fig. 8. In the present embodiment, at the password request display step (1156), a screen displaying "Please enter password" appears instead of the screen shown in FIG. 22 (d).

Next, the settlement server 30 creates the user's accounting information based on the purchase information received from the cashier terminal 10 and transmits it to the user terminal 10 (822). The user terminal 20 checks the accounting information, and when the check is completed (824), the completion indicating that the check is completed is completed. The notification is sent to the settlement server 30 (8 26).

When the settlement server 30 receives the completion notification from the user terminal 20, the payment server 30 checks the purchase information with the available amount of money of the user (828). Next, the settlement server 30 accesses the user account database 70 and performs settlement processing for recording purchase information (830). When the settlement is completed, the settlement server 30 sends a notice of settlement completion to the cashier terminal 10 (832), and sends a receipt to the user terminal 20 (834). The user terminal 20 displays a screen indicating that the payment has been completed (838). This is the end of the operation of the electronic payment system.

In this figure, cashier terminal information inquiry stage (804), transaction identification number collation stage (814), user information inquiry stage (816), check of accounting information (824), and purchase amount are available. The operations of the cashier terminal 10, the user terminal 20, and the settlement server 30 in the matching step (8 2 8) with the money amount are performed at the cashier terminal 10 in each stage of the first embodiment described with reference to FIG. , The user terminal 20 and the operation of the settlement server 30, and the description is omitted. In the inquiry step (8 14) of the transaction identification number in the present embodiment, the transaction identification number assigned to the registration number in the first embodiment described with reference to FIG. The number is compared with the transaction identification number transmitted from the user terminal 20.

In the electronic payment system according to the present embodiment, similarly to the electronic payment system according to the first embodiment, the user can easily and safely perform payment using a wireless communication device such as a pager or a portable terminal. it can. Further, also in the electronic payment system of the present embodiment, as in the electronic payment system of the first embodiment, the cashier terminal 10 does not communicate with the user terminal 20, so that communication with the user terminal 20 is not performed. It does not have to have a function.

Further, in the “loop settlement” in the present embodiment, the settlement server 30 receives transaction information from the user terminal 20 and further receives a confirmation notice regarding accounting information from the user terminal 20. And perform the settlement process. Therefore, as in the first embodiment described with reference to FIG. 13, fraudulent settlement at the cashier terminal 10 can be prevented. Further, in the present embodiment, user terminal 20 receives information from cashier terminal 10 but does not need to transmit information to cashier terminal 10. Therefore, similarly to the first embodiment, the “loop settlement” in the present embodiment can be performed by using a portable terminal having only one-way communication means such as a pager as the user terminal 20.

As another example, in the present embodiment, when the cashier terminal 10 receives the transaction identification number from the settlement server 30 (808), the cashier terminal 10 displays the transaction identification number and the cashier registration number. 10) Alternatively, the received transaction identification number and cashier registration number may be transmitted to the user terminal 20. In this case, the cashier terminal 10 has the communication function of the user terminal 20. The user terminal 20 receives the transaction identification number and the cashier registration number transmitted from the cashier terminal 10, and transmits the received transaction identification number and cashier registration number, and also the user ID to the settlement server 30. Thus, the user does not need to input the transaction identification number and the cash register number displayed on the cashier terminal 10.

As another example, in the present embodiment, the cashier terminal 1 ◦ transmitted the transaction request to the settlement server 30, but instead, the user terminal 20 transmits the transaction request to the settlement server 30. It may be sent to 30. In this case, the cashier terminal 10 displays the cashier registration number, and the user sends a transaction request to the settlement server 30 together with the displayed cashier registration number. Accordingly, the settlement server 30 can identify the cashier terminal 10 and assign it to the cashier registration number to issue a transaction identification number.

As another example, in the present embodiment, the settlement server 30 transmits the password request to the cashier terminal 10 (8 18), but instead, the settlement server 30 transmits the password request to the user terminal 20. You may send a password request.

Further, as another example, in the present embodiment, user authentication is performed using a password, but as in the first embodiment, visual authentication and a password may be used together. .

(Fifth embodiment)

FIG. 36 shows an electronic payment system according to a fifth embodiment of the present invention. In the present embodiment, user terminal 20 is an IC chip external to the housing of user terminal 20. 380. The IC chip 380 has, for example, a strong seal adhered to the back surface, so that it can be attached to the user terminal 20. As described above, since the IC chip 380 is externally attached to the housing, the radio wave generated by the IC chip 380 hardly affects the circuit inside the user terminal 20.

The IC chip 380 of the user terminal 20 stores an IC chip ID for identifying the present IC chip 380. The IC chip 380 transmits the stored IC chip ID by wireless communication.

On the other hand, the cashier terminal 10 has a sensor 320 that can wirelessly communicate with the IC chip 380 of the user terminal 20. In this regard, the electronic payment system of the present embodiment is different from the electronic payment systems of the other embodiments. In this embodiment, when the user terminal 20 approaches the sensor 320 of the cashier terminal 10, the sensor 320 reads the IC chip ID from the IC chip 380 of the user terminal 20. For example, the sensor 320 may read the IC chip ID from the IC chip 380 when the user terminal 20 approaches within approximately 10 cm.

The IC chip 380 has a unique IC chip ID. Therefore, the user terminal 20 can be identified by the IC chip ID of the IC chip 380 externally attached to the user terminal 20. That is, the sensor 320 can read the IC chip ID as the user terminal ID in place of the telephone number of the user information 600 in the first embodiment described with reference to FIG. 9, for example. In this regard, the cashier terminal 10 and the user terminal 20 according to the present embodiment are different from the cashier terminal 10 and the user terminal 20 according to the first to fourth embodiments.

Further, the IC chip 380 is detachably attached to the housing of the user terminal 20. Therefore, even when the user changes his / her own user terminal 20 to another mobile terminal due to, for example, model change, the user can attach the IC chip 380 to the mobile terminal after the change. Therefore, even when the user terminal 20 is changed, the user ID does not need to be changed.

The settlement server 30 of the present embodiment embeds a communication command for establishing communication between the user terminal 20 and the cashier terminal 10 in an electronic mail, and embeds the electronic mail in the user terminal. It has the function of transmitting to 20. In this respect, the settlement server 30 of the present embodiment is different from the settlement servers 30 in the first to fourth embodiments.

A settlement process in the electronic settlement system according to the present embodiment will be described with reference to FIG. 14 showing a settlement process in the electronic settlement system according to the first embodiment. In this embodiment, instead of the processing in the pattern code display step (104) and the pattern code reading step (106) in the first embodiment, the sensor 320 of the cashier terminal 10 is The user ID is read from the IC chip 380 of the user terminal 10. That is, after the cashier terminal 10 and the user terminal 20 start the loop settlement, when the user and the user terminal 10 are brought closer to the sensor 320 of the cashier terminal 10, the sensor 320 becomes The user ID is read from the IC chip 380 external to the user terminal 10.

The cashier terminal 10 accesses the settlement server 30 and transmits the user ID and the cashier registration number read from the user terminal 20 to the settlement server 30. At this time, the cashier terminal 10 may transmit the user ID and the cashier registration number to the payment server 30 or the sensor 320 may transmit it to the payment server 30.

Thereafter, the same processing as the cashier terminal information inquiry stage (109) to the transaction identification number issuing stage (1117) described in the first embodiment is performed. Next, in the accounting information and transaction identification number transmission stage (118), the processing unit 80 of the settlement server 30 transmits a communication instruction with the cashier terminal 10 corresponding to the received cashier registration number and a transaction identification number. Create an e-mail containing the number. Here, the communication command is a link command instructing to establish communication with the cashier terminal 10. The second communication unit 84 sends the created e-mail to the user terminal 20. Next, in the accounting information confirmation step (120), the message display section 350 of the user terminal 20 displays the received e-mail.

FIG. 37 shows the e-mail displayed by the message display section 350. First, the screen shown in Fig. 37 (a) is displayed, and then the screen shown in Fig. 37 (b) is displayed. Next, the following processing is performed in place of the pattern code reading step (124) in the first embodiment. That is, if the screen in Fig. 37 (b) is displayed Then, when the user presses the OK button, the communication between the user terminal 20 and the cashier terminal 10 is established by the communication command embedded in the e-mail, and the user ID and the transaction identification number are stored in the user terminal 20. To the cashier terminal 10. As described above, the user terminal 20 can establish communication with the cashier terminal 10 using the e-mail received from the settlement server 30.

Thereafter, the same processes as those from the user ID and transaction identification number transmission stage (126) to the receipt display (140) described in the first embodiment are performed, and the process in the electronic settlement system ends. In this manner, the user can make a payment with the cashier terminal 10 simply by pressing the button indicated in the received e-mail, and thus can efficiently perform the electronic payment processing .

In the present embodiment, the cashier terminal 10 transmits the purchase price information after the visual authentication (114). However, as another example, the user ID and the cashier registration number transmission step (108) ), The cashier terminal 1◦ may further transmit the purchase price information.
