For example, a setting may be made such that a certain piece of music is set to 20 points and another piece of music is set to 30 points, and the points set for each piece of music may be subtracted from the coupon to make a purchase point system (purchase (download)).

The coupon purchase processing in the electronic commerce system using the coupon of the present invention will be described with reference to the flow of FIG.

In FIG. 2, the processing on the user's terminal for purchasing the coupon is shown on the left side, and the processing on the merchandise sales site (server) for selling the coupon is shown on the right side. Each step in FIG. 2 will be described sequentially. First,
The user accesses the server using his / her own terminal, calls the coupon order screen, and inputs the customer ID assigned to each user and the number of coupon purchases on the order screen to enter the product sales site (server). Send (S101).

In the access processing, for example, the URL set in the server on the merchandise sales site side is specified at the customer terminal, and the initial screen is called. The coupon order screen is selected and displayed from the menu field set on the initial screen.

The server on the merchandise sales site has a customer ID
When the number of coupon purchases is received (S201), mutual authentication processing (S202, S102) with the user terminal is executed. The mutual authentication process uses, for example, a public key certificate,
A mutual authentication process using a public key cryptosystem according to a CC encryption algorithm or a common key cryptosystem according to a DES encryption algorithm is applied.

Determination of mutual authentication processing (S103, S20)
In 3), if it is determined that the mutual authentication has been established, the process proceeds to the next step. If the authentication has not been established,
The process ends as an error (S106, S208).

When mutual authentication is established and the validity of the communication partner is confirmed, the server on the merchandise sales site searches the coupon database (502 in FIG. 1, 502) based on the customer ID received from the user (S204). ), And extract a record corresponding to the customer ID.

FIG. 3 shows an example of the data structure of the coupon database. In the coupon database, as shown in FIG.
According to the customer ID as an identifier of each user, [customer name], [number of coupons issued], [unsettled number] indicating the number of coupons that have not been settled after issuance, and used by the user Coupon usage information such as [used number] indicating the number, [remaining number] indicating the number of available coupons, and [expiration date] indicating the expiration date of the issued coupon is stored.

On the other hand, the user inputs the payment method for purchasing a coupon, for example, payment information such as a credit card number and a bank account number, and transmits the information to the server on the merchandise sales site side. At the time of this data transmission, it is preferable to transmit the data after encrypting the transmission data using, for example, the session key generated in the above-described mutual authentication process.

The server on the merchandise sales site that has received the payment information from the user executes the decryption process if the received data is encrypted, and obtains the payment information of the user.
Execute payment processing based on the obtained payment information (S20)
5) Do it.

Next, the server on the merchandise sales site executes a data update process of the coupon database (S206) based on the executed settlement process. For example, FIG. 4 shows an example of a database update process in the case where the user with the customer ID [AA0018] in FIG. 3 purchases 10 coupons additionally and executes the settlement process.

In the e-commerce system using coupons of the present invention, new or additional purchase of coupons
A process for resetting the expiration date of the coupon already purchased is also executed. In the example illustrated in FIG. 4, as illustrated in (a), the user of the customer ID [AA0018] has the expiration date [2001].
/ 05/31] is held in the state of holding the remaining number of coupons set to 10. In this state, the customer ID [A
[A0018] suppose that the user made an additional purchase of ten coupon tickets on April 25, 2001.

The number of issued coupons set in the coupon database by this coupon additional purchase processing is 20 + 10 =
30, the remaining number is updated to 10 + 10 = 20, and the expiration date is changed from [2001/05/31] to [2001 /
07/25]. That is, the customer ID [AA
0018] has an expiration date of [2001/07 /
25], there are 20 usable coupons. In this example, the expiration date has been described as an example in which the expiration date is set to three months from the purchase date.
A product sales site such as one year can be set arbitrarily.

Returning to the flow of FIG. 2, the description will be continued. When the server on the merchandise sales site executes the update processing of the coupon database based on the coupon purchase processing data after the settlement processing, the server transmits a processing completion notification to the user terminal (S207). The user terminal receives the processing completion notification (S105), and the processing ends.

As shown in the data example of the coupon database shown in FIG. 3, each record stores unsettled number data. The unsettled number data is data corresponding to the number of coupon purchases for which the purchase processing request has been executed but the account has not been actually debited. In the flow described above, the settlement processing is described as an example of processing that is completed during the coupon purchase processing. However, when the cash withdrawal date from the account or the like is set on a specific month-by-month basis, for example, Executes, as a settlement process executed at the time of the coupon purchase process, only the confirmation of the user account or the scheduled debit with a credit card, and after this process, updates the coupon database and executes, for example, 10 If the ticket is not purchased and the settlement is not completed, a process of adding 10 to the unsettled number in the data is executed. Thereafter, the coupon database update process is executed again on the settlement processing day to set the unsettled number to 0 and the remaining number to be used to 1
The process of adding 0 is performed.

As described above, in the e-commerce system using coupons of the present embodiment, the expiration date of coupons remaining at the time of new purchase or additional purchase of coupons is determined according to the new coupon purchase processing. In this configuration, the user can use the coupon effectively without wasting consumption within the expiration date of the coupon. Also, on the merchandise sales site, by encouraging users with coupons whose expiration date is imminent to purchase additional coupons, it is possible to further promote the purchase of coupons and achieve an increase in sales value. Can be.

Next, the user uses his / her own coupon,
Alternatively, an inquiry process for confirming information such as an expiration date will be described with reference to the flow in FIG.

Also in this flow, the left side is the user side terminal using the coupon ticket, and in this case, the process is performed at the user side terminal that intends to perform the inquiry process. The right side is the processing of the merchandise sales site (server) that sells coupon tickets.
Each step of FIG. 5 will be sequentially described. First, users access the server using their own terminal,
The coupon usage status inquiry screen is called up, and the customer ID assigned to each user is input on the screen and transmitted to the product sales site (server) (S301).

The details of this processing are described in, for example, the URL set in the server on the merchandise sales site side at the customer terminal.
And call the initial screen. This process is executed as a process of selecting and displaying a coupon usage status inquiry screen from the menu field set on the initial screen.

The server on the merchandise sales site has a customer ID
Is received (S401), the coupon database (FIG. 3)
Is searched based on the customer ID received from the user (S402), and a record corresponding to the customer ID is extracted (S403).

[Unsettled number], [used number] indicating the number used by the user, [unused number] indicating the number of available coupons, and [expiration date] indicating the expiration date of the issued coupon Each information is stored. The server at the merchandise sales site extracts these data records.

Next, the server on the merchandise sales site side uses the remaining coupon number data included in the coupon database,
Then, a message master database search process for extracting a corresponding message from the message master database based on these data is performed.

FIG. 6 shows an example of the data structure of the message master database. As shown in FIG. 6, the message master database stores messages according to the remaining number of coupons,
And when the expiration date has passed (A), when the remaining number of coupons is 0 (B), and when the remaining number of coupons is insufficient for the purchase request product (C). This is a database that stores the corresponding messages.

The server on the merchandise sales site side, based on the remaining coupon data and the expiration date data contained in the coupon database, retrieves one message from these messages.
Extract the above messages. For example, if the remaining number of coupons is one or more and the number of remaining days of the expiration date is one day, the message of the message ID [A0029] [One day of the expiration date remains. Is taken out.

The server on the merchandise sales site sends the message extracted from the message master database and the data generated based on the record corresponding to the customer ID extracted from the coupon database to the user terminal (S
405).

The user terminal receives the data transmitted from the server on the merchandise sales site side (S302) and displays it on the display of its own terminal to check information such as the usage status of the coupon, the remaining number, and the expiration date. I do. Further, in the case where the coupon is purchased (S303, Yes), FIG.
The coupon ticket purchase process described with reference to FIG. If the coupon is not to be purchased (S303, No), the process ends.

Next, a coupon use process in which a user purchases a product using his or her own coupon will be described with reference to the flow of FIG.
