This summary of the invention does not necessarily describe all necessary features of the present invention. The present invention may also be a sub-combination of the above described features. The above and other features and advantages of the present invention will become more apparent from the following description of embodiments taken in conjunction with the accompanying drawings.
The invention will now be described based on the preferred embodiments, which do not intend to limit the scope of the present invention, but exemplify the invention. All of the features and the combinations thereof described in the embodiment are not necessarily essential to the invention.
An electronic settlement system according to the first embodiment of the present invention will be explained as follows. Applying the electronic settlement system of the present embodiment, a user, who read a mail order advertisement in a newspaper, a magazine, a mail order catalog and so on, can order an item and execute a settlement via a network using a user terminal such as a portable telephone or a portable terminal.
A transmission line 18, which is a communication line to connect the cashier server 14 or the virtual cashier terminal 12 with the synchronizing server 30, may be either a commercial telephone line or a private line. A radio transmission channel 28 is a transmission path of a radiotelephone communication to connect a user terminal 20 with a carrier server 40. A transmission line 38 is a communication line to connect the carrier server 40 with the synchronizing server 30, and may be either a commercial telephone line or a private line.
The cashier server 14 is a server system to represent distribution in a mail order, which is composed of virtual cashier terminals 12 in the server and performs billing of transactions to users.
The synchronizing server 30 performs a settlement of a commodity transactions processing between mail order retailers and users. The synchronizing server 30 connects the cashier server 14 with the user terminal 20 via a telecommunication network and performs data communications.
As shown in
The user terminal 20 directs to pay a value of the merchandise using credit means such as a credit card or a bankcard. An example of the user terminal 20 is a radiotelephone communication means such as a cellular phone. Another example of the user terminal 20 is a portable terminal such as a PDA or a notebook type personal computer and so on, which communicates by connecting to radio communication means such as a cellular phone.
The user terminal 20 connects to the carrier server 40 via the radio transmission channel 28. The carrier server 40 connects to the synchronizing server 30 via the transmission line 38. A direct communicating means does not exist between the virtual cashier terminal 12 and the user terminal 20.
The synchronizing server 30 acquires information about the billing of a commodity transaction by communicating to the virtual cashier terminal 12, and information about the paying of a commodity transaction by communicating to the user terminal 20, and then processing the settlement of transactions between the virtual cashier terminal 12 and the user terminal 20 by synchronizing the communication to the virtual cashier terminal 12 with the communication to the user terminal 20.
The synchronizing server 30 connects to the cashier database 50 accumulating the information of the cashier server 14, the user database 60 accumulating the information of the user terminal 20, and the user account database 70 accumulating the information of the credit account or the bank account of users. And the synchronizing server 30 searches each database and retrieves the information. The synchronizing server 30, the cashier database 50, the user database 60, and the user account database 70 may be arranged in a network of a credit company or a bank network. However, only the user account database 70 may be arranged in the network of a credit company or the bank network, and the synchronizing server 30 may be connected to the user account database 70 via the private line.
A configuration of a “synchronizing settlement” using the electronic settlement system of the present embodiment is described as follows. A “synchronizing settlement” is a method that does not communicate the virtual cashier terminal 12 with the user terminal 20 directly, but rather processes a transaction settlement between the virtual cashier terminal 12 and the user terminal 20, by synchronizing communication in real-time to the virtual cashier terminal 12 with the communication to the user terminal 20 via the synchronizing server 30 which communicates with both of the virtual cashier terminal 12 and the user terminal 20.
In the electronic settlement system, settlements of transactions are performed between a plurality of virtual cashier terminals 12 and a plurality of user terminals 20. The synchronizing server 30 needs to specify the virtual cashier terminal 12 billing the transaction and the user terminal 20 paying the transaction for each transaction in order to synchronize the communication to the virtual cashier terminal 12 with the user terminal 20 and to process the transaction of settlement between the virtual cashier terminal 12 and the user terminal 20.
In order to synchronize the communication to the virtual cashier terminal 12 with the communication to the user terminal 20, a cashier terminal identifying information, as an example of a transaction identifying information in order to identify a certain transaction, is defined. When the synchronizing server 30 connects and communicates to the cashier server 14, the synchronizing server 30 defines a cashier terminal identifying information which identifies a virtual cashier terminal 12 activated in the cashier server 14, and delivers the cashier terminal identifying information within a “link information” to the user terminal 20.
When the user answers the link information using the user terminal 20, the user terminal 20 delivers the cashier terminal identifying information to the synchronizing server 30. If a virtual cashier terminal 12 which matches the cashier terminal identifying information received from the user terminal 20 may be found in a plurality of virtual cashier terminals 12 issuing cashier terminal identifying information, the synchronizing server 30 synchronizes the communication to the virtual cashier terminal 12 with the communication to the user terminal 20. When matching cashier terminal identifying information may not be found, the user terminal 20 is not synchronized with any virtual cashier terminals 12. Thus, for a certain transaction identified by the cashier terminal identifying information, the synchronizing server 30 specifies the virtual cashier terminal 12 billing the transaction and the user terminal 20 paying the transaction using the cashier terminal identifying information, and synchronizes the communication to the virtual cashier terminal 12 with the communication to the user terminal 20, and processes the settlement. Therefore, without directly communicating the virtual cashier terminal 12 with the user terminal 20, the settlement of transactions may be performed between the virtual cashier terminal 12 and the user terminal 20.
User authentication performed by the synchronizing server 30 is described as follows. A cellular phone as an example of a user terminal 20 has a predetermined calling telephone number unique for each cellular phone, so that the predetermined calling telephone number is used with every dialing. The calling telephone number is unique to each cellular phone, and any other cellular phone can not make a phone call with the same calling telephone number. Therefore, as long as the original owner uses the certain cellular phone, the calling telephone number of a cellular phone may be used for a user specifying identification. That is, a cellular phone may work as an ID like a drivers license.
Concerning the case that the owner of a cellular phone lost his or her cellular phone and someone else uses the lost cellular phone, the cellular phone may be uniquely specified with the calling telephone number, but the user of the cellular phone may not be specified to the owner of the cellular phone. The electronic settlement system stores data corresponding to a calling telephone number of each cellular phone with the information of the owner of each cellular phone in the user database 60, and authenticates if the user of a cellular phone is the actual owner.
When the synchronizing server 30 connects to the user terminal 20, the synchronizing server 30 detects a calling telephone number of the user terminal 20, retrieves the user database 60 based on the calling telephone number, extracts information about the user, and authenticates the user. There are several authentication methods, such as visual authentication, password authentication, voice authentication, and so on. These authentication methods may be combined with each other. In case simple visual authentication is not secure enough, using complex authentication, combining with other authentication methods such as password authentication for example, may improve accuracy of the authentication.
Combining the “synchronizing settlement” and user authentication may realize an electronic settlement system that ensures security, protects privacy, and has a high level of reliability. Furthermore, a cellular phone or a portable terminal connecting for data communication to a cellular phone and so on has a portability, that is the user may take the terminal anywhere, and a simplicity, that is the user may communicate to a network via radio telephone communication from anywhere. Therefore, an electronic settlement system of the present embodiment enables to realize an electronic settlement with high reliability, security, and convenience.

When the user chooses “transmission” in the transaction ID input information, the user terminal 20 is connected to the synchronizing server 30. The transaction ID is transmitted to the synchronizing server 30 (204). The user may choose “cancel” in the transaction ID input information if he or she wants to quit the settlement processing. This cancellation processing may be used in a case where the settlement processing may not be performed even when inputting a transaction ID correctly, caused by a communicating disorder and so on.
The synchronizing server 30 receives the transaction ID transmitted from the user terminal 20, using the transaction ID, makes an inquiry to a cashier data (206).
Referring to
Referring to
The synchronizing server 30 may detect the calling telephone number of the user terminal 20 when the user chooses the synchronizing settlement menu in the user terminal 20 and the user terminal 20 makes the first access to the synchronizing server 30. In another case, the synchronizing server 30 may detect the calling telephone number of the user terminal 20 when the user inputs the transaction ID to the user terminal 20 and the user terminal 20 transmits the transaction ID to the synchronizing server 30.
When the user registration is verified, user data is retrieved from the user database 60 (2092). Information about the payment history of the user is recorded in the user data. If the user has a problem in his or her payment history on his or her credit card or his or her bankcard and so on, it is checked based on the information (2094). When any problem is found in his or her payment history, a message “we cannot accept your access.” is transmitted to the user terminal 20 (2096). Information notifying that settlement is rejected, shown in
Referring to
When the password transmitted from the user terminal 20 is incorrect, it is checked whether the required password count n is 2 or more (2116), if not, it goes back to the processing of 2106 and requests the password again. If the required password count n is 2 or more, the authentication processing is finished (2118) and an invalid message is transmitted to the user terminal 20 (2120). Because the authentication is not confirmed, information shown in
In the password verification 2114, when the synchronizing server 30 verifies the correct password, the processing of the password authentication 210 is finished.
Referring back to
The synchronizing server 30 creates “link information” (218). The link information includes cashier server identifying information to identify a virtual cashier terminal 12 connected to the synchronizing server 30 and cashier identifying information to identify the cashier server 14, such as the name of the retailer and a welcome message. The synchronizing server 30 sends the link information to the user terminal 20 (220). The user terminal 20, receiving the link information from the synchronizing server 30, displays the welcome message shown in
When the user chooses “cancel” at this point, the electronic settlement may be canceled. This cancellation processing is performed in such a case that the user inputted a wrong transaction ID and an unwanted mail order site is shown in the display and so on.
The synchronizing server 30 establishes synchronization when a link information confirming signal is received from the user terminal 20 (226). Referring to
The user terminal 20 transmits the link information confirming signal corresponding to the link information sent from the synchronizing server 30, so that the synchronizing server 30 establishes “synchronization” status.
First, the synchronizing server 30 is on an “access wait” status, that is waiting to be accessed by the user terminal 20 and for a link information confirming signal to be sent. In this “access wait” status, if a user terminal 20 using the same link information to be allocated to the virtual cashier terminal 12 accesses, the synchronizing server 30 establishes one to one “synchronization” status between that virtual cashier terminal 12 and the user terminal 20, and realizes a synchronization of the communication to the virtual cashier terminal 12 with the communication to the user terminal 20. Access from a plurality of the user terminals 20 will not be matched for one link information.
A time out limit is set up for the “access wait” status of the synchronizing server 30, and limits the access wait period with the user terminal 20 to a predetermined length, for example, 3 minutes. When no answer is obtained for the link information issued from the user terminal 20 after the time out limit, the synchronizing server 30 shuts down the connection to the virtual cashier terminal 12, and initializes it. This time out function is set up in order to avoid trouble for cases where a user cancels the processing or that a communicating condition of the user terminal 20 with the synchronizing server 30 is poor so that data communication cannot be performed normally, and so on.
As shown in
When the user terminal 20 transmits the link information confirming signal, it is checked whether a virtual cashier terminal 12 on the “synchronizing wait” status corresponding to that link information is found (2268), if not, it transmits a synchronizing error message to the user terminal 20 (2270). The user terminal 20 displays the synchronizing error message on the display (2272), and then the user terminal 20 shuts the settlement processing down, and finishes the settlement.
When a virtual cashier terminal 12, which corresponds to the link information transmitted from the user terminal 20, is found and on the “synchronizing wait” status, the synchronizing server 30 establishes a “synchronizing” status between that virtual cashier terminal 12 and the user terminal 20 and synchronizes the communication with the virtual cashier terminal 12 and the communication to the user terminal 20 (2274).
Referring back to
The user terminal 20 prompts the user to input to the user terminal 20 an order of an item, based on the product information received from the synchronizing server 30, (234). Referring to
Referring back to
The virtual cashier terminal 12 calculates a purchase amount based on the order information received from the synchronizing server 30 (240), and transmits to the synchronizing server 30 the purchase amount information including the purchase amount (242). The synchronizing server 30, receiving the purchase amount information from the virtual cashier terminal 12, performs the processing of the available amount checking 244.

Cashier terminal identifying information, as an example of transaction identify numbers described above, is information to identify the virtual cashier terminal 12, with which the user terminal 20 synchronizes to perform the transaction. A cashier terminal identifying number, for example, created by random number generation may be used as the cashier terminal identifying information. But, when the random number generation is used, a same cashier terminal identifying number may be allocated on a plurality of the virtual cashier terminals 12. In such a case, the synchronizing server 30 may not correspond a virtual cashier terminal 12 to the user terminal 20 for the transaction performed by the user terminal 20. Therefore, cashier terminal identifying numbers are allocated in the way that the same cashier terminal identifying number may not be used two or more times in a predetermined period. On the other hand, the cashier terminal identifying number may be used again after the predetermined period. Thus, without increasing the digits of the cashier terminal identifying number, uniqueness of the cashier terminal identifying number may be maintained.
The synchronizing server 30 has a further function that limits the allocation of the cashier terminal identifying number, which does not issue the cashier terminal identifying number the same as the cashier terminal identifying number of the virtual cashier terminal 12 in the “access wait” status, and ensures to prevent competition of the cashier terminal identifying number.
When there are many mail order servers, the cashier terminal identifying numbers created by random number generation may compete with each other. In such a case, in order to avoid the competition of numbers allocated by two or more cashier servers, the range of the generated random numbers for the cashier terminal identifying number to each cashier terminal may be limited.
The cashier terminal identifying number is used for corresponding to the user terminal 20 the virtual cashier terminal 12 identified by the cashier terminal identifying number and for establishing the synchronization of the communications each other. Therefore, once “synchronization” is established to the cashier terminal identifying number issued by the synchronizing server 30, and the “access wait” is released, the same cashier terminal identifying number may be used for another transaction. The cashier terminal identifying number, even though it is a number for identifying transactions, does not need to be a large digit number such as a transaction ID, which is a number unique to every transaction; but needs to be large enough to keep the uniqueness for the period being allocated to the transaction and establishing the “synchronization”.
In the description above, the synchronizing server 30 sends to the user terminal 20 cashier identifying information and cashier terminal identifying information as an example of a transaction identifying number in a form of “link information”. The user chooses “link” displayed on the user terminal 20. Then, the link information confirming signal, including the cashier terminal identifying information, is transmitted to the synchronizing server 30.
In the above described settlement processing, when the synchronizing server 30 transmits the settlement completion notification 254 to the virtual cashier terminal 12, the synchronizing server 30 may retrieve a part of an attribute information about the user of the user terminal 20 which performs the payment of the settlement from the user database 60, and may transmit the information to the virtual cashier terminal 12. The attribute information about the user transmitted to the virtual cashier terminal 12 preferably may be information about sex or age of a user and so on. On the other hand, personal information such as a name, an address, and a credit card number should not be included in the attribute information. The cashier server 14 may retrieve the information about the user who performed the payment of the settlement, may store the information about the item and the user data, and may form a purchase history database in the retailer's database. Thus, the retailer may detect buying behavior, such as an age group for users of a certain item from the purchase history stored in the database, so that the history may be used for marketing.
When the synchronizing server 30 receives the purchase amount of items from the virtual cashier terminal 12, the synchronizing server 30 may also receive the name or price of purchased items and detailed information of purchased items. The synchronizing server 30 may store this information in the user database 60 as a user purchase history. The user terminal 20 may inquire about the user purchase history to the synchronizing server 30, and receive the user purchase history from the synchronizing server 30.
An electronic settlement system of the present embodiment enables users electronic ordering and payment of mail order including magazines, catalogs and so on. The user may confirm if he or she is connected to the mail order site he or she wanted before performing his or her order with the link information displayed on the portable terminal. The retailer of mail order may specify the authentication method so that the settlement may be performed after the authentication of the user with the user password and so on.
An electronic settlement system according to the second embodiment of the present invention will be described as follows. Applying the electronic settlement system of the present embodiment, as the first embodiment, a user may order items and execute settlement via a network. The electronic settlement system of the present embodiment adopts voice authentication for the authentication method for user authentication. The rest of the embodiment is almost the same as the first embodiment.
The voice authentication center 42 connects to the carrier server 40. When a user terminal 20 dials via a radiotelephone communication, the voice authentication center 42 authenticates the user by the voice from the user terminal 20. The voice authentication center 42 has a user voice database 44, and inquires a user voice from the user terminal 20 to the user voice registered in advance in the user voice database 44. The user voice database 44 stores voice information registered by the user of the user terminal 20 in advance. The voice information of the user is, for example, the voice data of a predetermined registered word the user speaks.
The voice authentication center 42 connects to the cashier database 50 and the user database 60, and checks registration status and payment history of the user. The voice authentication center 42 may also retrieve the cashier server registered in the cashier database 50 based on the transaction ID the user transmitted, and checks the registration of the cashier server.
The other components marked the same as in
Referring to
A difference of the present embodiment from the first embodiment is, when a user terminal 20 chooses the synchronizing settlement menu and starts a settlement, the user terminal 20 is connected to the voice authentication center 42 via the carrier server 40, and a voice authentication is performed. Other processing are the same as the first embodiment. Here, the processing that are different from the first embodiment will be described.
First, the user chooses the electronic settlement menu from the user terminal 20 and starts an electronic settlement (300). Information directing the user to input an “ordering telephone number” is displayed on the user terminal 20. The user inputs an “ordering telephone number” listed in an advertisement of a mail order or a catalog (302), and a telephone call is made (304). “Ordering telephone number” is a telephone number of the voice authentication center 42. The user terminal 20 is connected to the voice authentication center 42 with a telephone communication line. Information from the user terminal 20 to the voice authentication center 42 is transmitted by voice or input by keypad. Information from the voice authentication center 42 to the user terminal 20 is sent by voice direction or voice guidance providing information.
When the voice authentication center 42 receives a telephone call from the user terminal 20, the voice authentication center 42 inquires the user data (306). Referring to
An example of the user terminal number of the user terminal 20 is a calling telephone number. When the user terminal 20 is set a calling number delivery service, the receiver may detect the calling telephone number. When the user terminal 20 does not set a calling number delivery service, the receiver may not detect the calling telephone number. In such a case the voice authentication center 42 sends to the user terminal 20 voice guidance prompting the user to set the calling number delivery service of the user terminal 20.
The voice authentication center 42 accesses the user database 60 (3062), and checks if the user terminal 20 has registered based on the user terminal number (3064). If the user terminal 20 does not have a user registration, the voice authentication center 42 transmits to the user terminal 20 voice guidance notifying the user terminal 20 is not registered in the database (3066), shuts down the connection to the user terminal 20 (3068), and finishes the processing.
When the user registration is verified, the user data is retrieved from the user database 60 (3070). Information about payment history of the user is written in the user data. The voice authentication center 42 checks if the user has a problem in his or her payment history on his or her credit card or his or her bankcard based on the information (3072). When any problem is found in his or her payment history, the voice authentication center 42 transmits the user terminal 20 voice guidance to notify that the authentication service is not available (3074), shuts the connection to the user terminal 20 down (3076), and finishes the processing. When the user does not have any problem with his payment history, the voice authentication center 42 finishes the processing of the user data inquiry 306, and goes to the next step.

Referring back to
The input transaction ID is transmitted to the voice authentication center 42 (314). The voice authentication center 42 makes an inquiry to a cashier data based on the transaction ID received from the user terminal 20 (315).
When the cashier server corresponding to the transaction ID is registered, the cashier data is retrieved (3188). Information such as a retailer name, an authentication method, and an access number to the cashier server 14 are registered in a cashier data. An access number of the cashier server 14 is retrieved from the cashier data. The access number is, for example, a connecting telephone number of the cashier server 14. When the cashier data is retrieved, the voice guidance confirming the cashier data is transmitted to the user terminal 20. For example, voice message “OO mail order catalog July is chosen. If correct, please hang up and wait for a call back from the ordering center. If incorrect, please input the transaction ID again” is sent to the user terminal 20.
Referring back to
The synchronizing server 30 receives an order receiving instruction from the voice authentication center 42 and receives the transaction ID (316). The synchronizing server 30 accesses the cashier server 14 corresponding to the transaction ID (320). The cashier server 14 activates a virtual cashier terminal 12 (322). The virtual cashier terminal 12 is an apparatus or a processing performing as a cashier. The virtual cashier terminal 12 may be a terminal device provided in the cashier server, or may be a program activated in the cashier server. The virtual cashier terminal 12 is connected to the synchronizing server 30 (323).
The synchronizing server 30, when the server connects to the virtual cashier terminal 12, creates a “link information” in order to identify a transaction to the virtual cashier terminal 12 (324). The link information in the present embodiment is an example of a transaction identifying numbers that identifies the transaction between the user terminal 20 and the virtual cashier terminal 12. The synchronizing server 30 synchronizes the communication to the user terminal 20 with the communication to the virtual cashier terminal 12 based on the link information, and processes the settlement of the transaction. The link information includes not only the transaction identifying number but also cashier identifying information that identifies a cashier server 14 such as a name of a mail order retailer or a welcome message.
The synchronizing server 30 sends the link information to the user terminal 20 (326). The user terminal 20, receiving the link information from the synchronizing server 30, displaying a welcome message on the screen as shown in
The user, choosing “cancel” on the display, may cancel the electronic settlement. This cancellation processing is performed in such a case that because the user inputs an incorrect transaction ID, an unwanted mail order site is displayed.
The synchronizing server 30, receiving the link information confirming signal from the user terminal 20, establishes a synchronization (332).
The settlement processing after the synchronization processing (332) will not be described here, as the processing are the same as the first embodiment.
Here, in the present embodiment, the voice authentication center 42 performs the processing of cashier data inquiry 315 and transmits the transaction ID to the synchronizing server 30. As another case, at the point of the processing when the user voice authentication 308 is completed, the voice authentication center 42 may transmit the information of the completion to the synchronizing server 30. In this case, the synchronizing server 30 performs the processing from the processing of voice guidance transmission 310 to the processing of the cashier data inquiry 315.
The electronic settlement system of the present embodiment authenticates a user by his or her voice before the electronic settlement, so that may ensure a high quality authentication.
The electronic settlement system according to the third embodiment of the present invention will be described as follows. Applying the electronic settlement system of the present embodiment, as the first embodiment, a user may order items and execute settlement via a network. The electronic settlement system of the present embodiment adopts image authentication for an authentication method for user authentication. The rest of the embodiment is almost the same as the first embodiment.
The image authentication center 46 authenticates a user based on an image transmitted from the user terminal 20. The image authentication center 46 has a user image database 48, and verifies an image transmitted from the user terminal 20 with the user image previously registered in the user image database 48. Image data of a user's facial portrait, image data of an iris or a retina of the user, or image data of a user's fingerprint may be used for the user image. The user registers this image data as authentication data in the user image database 48 in advance.
The other components marked the same as in
If the image data transmitted from the user terminal 20 is not matched with the image data retrieved from the user image database 48, whether the image data require count n is 2 or more is checked (2716), if not, it goes back to the processing 2706 and requests the image data again. If the image data require count n is 2 or more, the authentication processing is finished (2718) and an invalid message is transmitted to the user terminal 20 (2720). Because the authentication is not confirmed, information that the settlement service is not available is displayed on the user terminal 20 (2724).
In the image data verification 2714, when the synchronizing server 30 verifies the image data has been transmitted from the user, the processing of the user image data authentication 211 is finished.
The electronic settlement system of the present embodiment may ensure a safe electronic settlement for a user by prompting the user to transmit the image data that identifies an individual such as a facial portrait, iris or retina, or finger print in order to authenticate the user. With the image authentication, it differs from voice authentication that needs to connect a cellular phone to an audio carrier, using a data packet communication facility of a cellular phone, the authentication and the settlement may be performed in succession.
An electronic settlement system according to the fourth embodiment of the present invention will be described as follows. Applying the electronic settlement system of the present embodiment, as the first embodiment, a user may order items and execute settlement via a network. The present embodiment differs from the first embodiment as follows. The user does not need to input a transaction ID to identify a cashier server 14 which performs the mail order merchandise. The user may order an item by making a telephone call to an order-receiving center of the mail order merchandise, and may verbally explain the order to an order-receiving operator.
The order-receiving center 15 receives an order by telephone for mail order merchandise. At the order-receiving center 15, an operator receives an order from a user by telephone, the operator ensures the order, creates an order list using an order receiving management means of the order-receiving center 15. The order-receiving center 15 retrieves identifying information of the user terminal 20, such as a calling telephone number of the user terminal 20. When the user terminal 20 is set a calling number delivery service, the receiver may detect the calling telephone number. When the user terminal 20 does not set the calling number delivery service, the receiver can not detect the calling telephone number. In such a case, the operator asks the user his or her calling telephone number.
The order-receiving center 15, using a communicating means 19, transmits the calling telephone number of the user terminal 20 and the order list to the cashier server 14, and activates the virtual cashier terminal 12 to bill the transaction. The communicating means 19 may be either a commercial telephone line or a private line. A LAN may be used for connecting the order-receiving center 15 with the cashier server 14.
The other components marked the same as in
The cashier server 14 activates the virtual cashier terminal 12 (322). The virtual cashier terminal 12 is an apparatus or a processing performing as a cashier, may be a terminal device provided in the cashier server, or may be a program activated in the cashier server. The virtual cashier terminal 12 is connected to the synchronizing server 30, and transmits identifying information of the cashier server 14 (323).
The synchronizing server 30 makes an inquiry to the cashier data based on the identifying information of the cashier server 14 transmitted from the virtual cashier terminal 12 (315). Because the processing of the cashier data inquiry 315 is the same as the processing of the cashier data inquiry 206 in the first embodiment, the processing is not described here.
The synchronizing server 30 creates “link information” in order to identify a transaction to the virtual cashier terminal 12 (324). The link information includes cashier terminal identifying information to identify the virtual cashier terminal 12 connected to the synchronizing server 30 and cashier identifying information that identifies a cashier server 14 such as a name of a mail order retailer or a welcome message. The cashier terminal identifying information is an example of a transaction identifying number, and identifies a transaction between the user terminal 20 and the virtual cashier terminal 12. The synchronizing server 30 synchronizes the communication to the user terminal 20 with the communication to the virtual cashier terminal 12 based on the link information, and performs the settlement processing.
The synchronizing server 30 sends the link information to the user terminal 20 (326). The user terminal 20 receives the link information from the synchronizing server 30, and displays a welcome message on the screen as shown in
The user, choosing “cancel” on the display, may cancel the synchronized settlement. This cancellation processing is performed in such a case that the user inputs an incorrect transaction ID so that an unwanted mail order site is displayed and so on.
The synchronizing server 30, receiving the link information confirming signal from the user terminal 20 and establishes synchronization (332).
The synchronization processing 332 will not be described here hence the processing are the same as the first embodiment. When the synchronization is established, the synchronizing server 30 transmits a synchronization signal to the virtual cashier terminal 12 (334). The virtual cashier terminal 12, receiving the synchronization signal, calculates a purchase amount based on the order list received from the order-receiving center 15 (346), and transmits the purchase amount information including the order and the purchase amount to the synchronizing server 30 (348). The synchronizing server 30 performs the password authentication (349). Because the processing of the password authentication 349 is the same as the processing of the password authentication 210 in the first embodiment, the processing is not described here.
The password authentication 349 performed by the synchronizing server 30 is based on the authentication method appointed by the cashier server 14 in the processing of the cashier data inquiry 315. The cashier server 14 may appoint the authentication method as the password authentication is performed when the purchase amount exceeds a predetermined limit. In the other case, the user may appoint an authentication method. For example, the authentication method to perform the password authentication is previously appointed in the user database 60, in order to prevent improper use in such a case that the user terminal 20 is stolen. The synchronizing server 30 may retrieve the authentication method the user appointed from the user database 60 in the processing of the user data inquiry 306, may be combined with the authentication method appointed by the cashier server 14, and may decide the authentication method.
After the password authentication processing 349, the processing from the available amount checking 350 to the completion of the settlement are the same as the processing of the first embodiment, therefore the processing is not described here. The virtual cashier terminal 12 receives a settlement completion notification from the synchronizing server 30 (360), and transmits an ordering direction to the order-receiving center 15 (367). The order-receiving center, receiving the order, performs a transaction of order to a shipping center (368). The order received from the virtual cashier terminal 12 includes the calling telephone number as an identifying number to identify the user terminal 20, and the order-receiving center 15 may specify the order received form the user terminal 20 based on the calling telephone number.
The order-receiving center 15 may answer another user after transmitting the order to the virtual cashier terminal 12 in the processing 313. The order-receiving center 15 may specify the order, replace the order list to an item list in the order, and direct to the shipping center at the point of the processing 367, when the order is received from the virtual cashier terminal 12.
In the above described embodiment, the calling telephone number is used for identifying information of the user terminal 20. In another case, the synchronizing server 30 sends the link information based on the calling telephone number of the user terminal 20. An e-mail address of the user may replace the calling telephone number, and the link information is transmitted to the user terminal 20 by e-mail.
Applying the electronic settlement system of the present embodiment, the user does not need to input the transaction ID to identify the cashier server 14 to merchandise the mail order. The order may be performed by a telephone call to the order-receiving center of the mail order retailer in a dialog with the order receiving operator. The user does not need to input the ordering information about the item from the user terminal 20. Therefore, the user may order and settle the mail order transaction simply and easily. Especially, when the user uses a cellular phone for the user terminal 20, telephone communication is easier than the input of letters and numbers. Therefore convenience of the system is improved.
A modification of the present embodiment is described as follows. The electronic settlement system described above may be applied to a settlement over the counter in a store. After a clerk finishes an accounting procedure for a purchase by a customer at a cashier terminal, the clerk inquires the calling telephone number of the user terminal 20 or an e-mail address of the customer, and inputs to the cashier terminal. The cashier terminal transmits the calling telephone number of the user terminal 20 or the e-mail address of the customer to the synchronizing server 30. The synchronizing server 30 sends the link information to the user terminal 20 based on the calling telephone number of the user terminal 20 or the e-mail address of the customer received from the cashier terminal. The link information includes cashier information of the cashier of the store. The user may confirm the cashier by the link information displayed on the user terminal 20. The user terminal 20 transmits a link information confirmation signal to the synchronizing server 30. The synchronizing server 30 establishes synchronization of the communication with the cashier in the store. Thus, the electronic settlement is the same as the electronic settlement system described above and may be performed between the user terminal 20 and the cashier terminal in the store.
In the above described modification, instead of the customer giving the calling telephone number of the user terminal 20 or the e-mail address of the customer, the user terminal 20 may transmit the calling telephone number of the user terminal 20 or the e-mail address of the customer using a light communication such as an infrared communication or a short range wireless communication. In another case, the user terminal 20 may display the calling telephone number of the user terminal 20 or the e-mail address of the customer on the display in the form of a pattern code such as a barcode or a cyber code which is a two dimension bar code. The customer allows a pattern code reader provided in the cashier terminal to read a pattern code displayed on the user terminal 20, and sends the calling telephone number of the user terminal 20 or the e-mail address of the customer.
The synchronizing server 30 as an example of the settlement apparatus in the electronic settlement system according to the first, second, third, and fourth embodiments may be realized using a general-purpose computer.
A floppy disk drive 614 reads data or programs from a floppy disk 624 and provides this to the CPU 602. A CD-ROM drive 616 reads data or programs from a CD-ROM 626 and provides this to the CPU 602. A first communication interface 618 connects to a transmission line 18 and communicates data. A second communication interface 620 connects to a transmission line 38 and communicates data. A database interface 612 connects to databases 622 and communicates data with the database. Furthermore, the synchronizing server 30 has an interface to connect with a display 628 so that the administrator may watch an operational status of the synchronizing server 30, or check the setting information using the display 628.

The processing, performed by the CPU 602 operating the computer 600, of the settlement processing module 640, the first communication module 642, the second communication module 644, and the database retrieve module 646, are the same as each of the settlement processing unit 80, the first communication unit 82, the second communication unit 84, and the database retrieving unit 86 in the synchronizing server 30 according to the first, second, third and fourth embodiment; therefore these processing will not be described here.
The floppy disk 624 or CD-ROM 626 shown in
These programs may be read to RAM directly from the recording media and executed, or be installed to the hard disk drive once, then read to RAM and executed. Furthermore, these above described programs may be stored in a single recording medium or a plurality of recording media. In other cases, these programs may be stored in an encoded form.
Besides a floppy disk and a CD-ROM, an optical recording media such as a DVD, a magnetic recording media such as an MD, a magnetic optical recording media such as a PD, a tape device, and a semiconductor memory such as an IC card or miniature card and so on may be used for a recording media. In other cases, using a store device such as a hard disk or a RAM provided in a server system for a recording media, connected to a private telecommunication network or an Internet, the programs may be provided to the synchronizing server 30 via a communication network. Such recording media are used only for manufacturing the synchronizing server 30, so that it is obvious that manufacturing and distribution of such recording media as vocation constructs infringement of a patent based on the present application.
In the first, second, third, and fourth embodiments described above, the transmission line 18 connecting the cashier server 14 with the synchronizing server 30 may be a wireless communication or an Internet, other than a commercial telephone line or a private line. When the transmission line 18 is the Internet, in order to ensure security of the data communication to the synchronizing server 30, it is desirable to choose a high security communication method.
In another case, a bit filtering means is provided on a communication pathway between the carrier server 40 and the synchronizing server 30 and/or a pathway between the cashier server 14 and the synchronizing server 30. The bit filtering means may detect data format or bit pattern of data sent between the user terminal 20 or the cashier server 14 and the synchronizing server 30. Applying the present invention, because confidential information such as personal information of user is not sent between the synchronizing server 30 and the user terminal 20 or the cashier server 14 so that the data does not need to be encrypted. Thus, the bit filtering means may observe the data format and the bit pattern of the communicated data and find an unexpected access pattern easily. Therefore, false access to the electronic settlement system or destroying access may be stopped.
As described above, according to the electronic settlement system of the first embodiment, the user, who read a mail order advertisement in a newspaper, a magazine, a mail order catalog and so on, may order items and execute settlement electronically. The user also may confirm if the connected site is the correct mail order site he or she wanted by a link information displayed on information in his or her portable terminal before confirming his or her order. The retailer of the mail order, by appointing the authentication method, may settle after authentication of the user by a password and so on.
According to the electronic settlement system of the second embodiment, the electronic settlement is performed after the user is authenticated with his or her voice. Thus, high accuracy authentication is ensured.
According to the electronic settlement system of the third embodiment, authentication of the user is performed by letting the user to transmit identifying information image data of the user as an individual such as a facial portrait, an iris, a retina, or a fingerprint of the user, security of the electronic settlement is ensured. Applying image authentication, which differs from the voice authentication, using a data packet of communication facility attached to the cellular phone, a cellular phone does not need to be connected to the voice carrier, so that the authentication and the settlement may be performed successfully.
According to the electronic settlement system of the fourth embodiment, the user does not need to input a transaction ID to identify the cashier server 14 which performs the mail order merchandise, the order of an item may be performed by making a telephone call to the mail order-receiving center, and verbally explained to a order-receiving operator. The user does not need to input ordering information of the item from the user terminal 20, and ordering and settling the mail order is convenient.
The electronic settlement system of the present invention has the following advantages for the mail order retailer. Based on the uniqueness of the calling telephone number of a cellular phone, a secure user authentication may be ensured. On the other hand, because the system has a selection of authentication methods, the accuracy of the authentication may be easily varied corresponding to a settlement amount or a situation of the settlement.
The electronic settlement system of the present invention has the following advantage for users. Carrying a cellular phone, which is a communication terminal with a very good portability, a transaction may be electronically settled anytime and anywhere; therefore the user does not need to carry cash, a credit card, a bank card, or an IC money card and so on. Furthermore, the user, using a data packet communication facility of the cellular phone, may check if the payment is withdrawn from his or her account, his or her available amount, his or her purchase history, and so on.
The electronic settlement system of the present invention has the following advantage for a credit card company. Applying the authentication method using a cellular phone may discourage a false use of stolen cards. Because a credit settlement may be performed electronically using a cellular phone, issuing a credit card or management of a credit card is no longer needed; costs may be reduced. Furthermore, using a combination authentication method, in a case that a person responsible in the credit card company and so on moved data falsely, settlement accounts of users may be protected from false use.
Although the present invention has been described by way of exemplary embodiments, it should be understood that many changes and substitutions may be made by those skilled in the art without departing from the spirit and the scope of the present invention which is defined only by the appended claims.
