Description

Auction System {AUCTION SYSTEM}

The present invention relates to an auction system, and more particularly, to an auction system for auctioning goods through an information network.

In recent years, with the development of information and communication, auction of goods has been carried out through the Internet, for example.

In this conventional auction system, the WWW server presents to the bidder a competition (auction) screen that includes information such as product information, the number of items of the product, the current highest bid amount, the number of bidders, and the like on the homepage. Prompts the entry of a bid price. When a bid price for a product is input from the bidder, it is stored in the storage unit once, and the higher bid price is selected as the winning bid price among the bid prices input within the predetermined period.

The WWW server then presented the information indicating the successful bid to the successful bidder, confirmed the purchase intention to the successful bidder, and requested that the successful bid price be paid to a predetermined account of the auction organizer by the financial institution to which the successful bidder with the willingness to purchase was joined.

However, in the conventional auction system, since the current highest bid amount is presented on the above-mentioned competition (auction) screen, there is a problem in which a person who gives up a bid appears that the motivation to participate decreases every time the highest bid price is confirmed. .

The present invention has been made in view of the above problems, and an object thereof is to provide an auction system that can contribute to improving the bidding participation of bidders.

In addition, the flowchart shown in FIG. 3 operates by the control part 29 according to the control program stored in the hard disk HD provided in the host server 13.

In the present embodiment, in particular, the user terminal 15 of the user is urged to operate on the random number generation process, and the hosting server 13 generates a random number according to the operation information received from the user terminal 15, Accordingly calculates the addition amount.

Now, for example, power is applied to a user terminal 15 such as a personal computer or a portable communication terminal installed in a user's home, and a WWW browser is started. Also, the URL address of an auction company is input to the WWW browser and the Internet 11 is displayed. When transmission to the network is started, the line is first connected to the telephone number of the provider that is connected to the connection, and then connected to the communication processing unit 21 of the host server 13 via the provider. The user terminal also transmits a home page request to the communication processing unit 21.

Here, in step S10, the host server 13 connected to the user terminal 15 via the Internet 11 reads the information of the homepage stored in advance in response to a request for the homepage from the user, and the user terminal via the Internet 11. Send to (15). As a result, the top screen (display screen 31) of the home page is displayed on the user terminal 15 as shown in FIG.

When the user clicks on the icon 33 of the "computer" using a mouse, the display color of the selection display button 35 is reversed, indicating that the icon is selected, and the next display screen 37 shown in FIG. Go to. In Fig. 6, a product item relating to "computer" is displayed. When the icon 39 of "hardware" is clicked on here, the display color of the selection display button 41 is reversed, and the process moves to the next display screen 43 shown in FIG. 7 shows a product item relating to "hardware." When the icon 45 of the "notebook" is clicked on here, the display color of the selection display button 47 is reversed, and the process moves to the next display screen 49 shown in FIG.

At this time, a commodity information request (not shown) for requesting commodity information relating to "laptop" from the user terminal 15 is transmitted to the host server 13. Receiving a product information request from the user terminal 15, the host server 13 retrieves and reads the product information related to the "notebook" from the database stored in the hard disk 23 in step S20, and reads into the "notebook". A page for presenting the content of the bidding is generated and transmitted to the user terminal 15.

8, the actual price, the limited number, the minimum bid price, etc. are displayed about the goods A-D of each manufacturer regarding "notebook." Here, when the icon 51 of "goods A" is clicked, the display color of the selection display button 53 is reversed, and it shifts to the next display screen 9 shown in FIG.

In addition to information such as photographs, product descriptions, product introductions, and after-sales services for the products A of the "notebook", FIG. 9 shows information such as actual prices, minimum bid prices, and limited numbers of the products A. Is indicated.

In this embodiment, the description of the procedure for member registration is omitted. In addition, the member registered in the host server 13 receives a member number and stores the member's e-mail address in a database.

When the icon 57 of "bid now !!" is clicked, the display color of the selection display button 59 is reversed, and the flow moves to the next display screen 61 shown in FIG.

In FIG. 10, a password input area 65, a bid price input area 63, in addition to a photograph about the product A of the "notebook" selected by the user, information on the actual price of the product, the lowest bid price, a limited number, etc. As the payment method, the "cash collective" area 67, the "installation" area 69, and the "slot bonus" icon 71 are displayed.

The password is an authentication number unique to each user given from the host server at the time of user registration. Here, the password will be described as having been previously given from the host server.

Here, the above-mentioned password is input into the password input area 65 as bid application information by user's operation, and then a bid price is input into the bid price input area 63, and "cash collective" or " Installment "is inputted, and when the" to slot bonus "icon 71 is clicked, it moves to the next display screen 73 shown in FIG. And it accepts acceptance of up to 3 times of bids from the same bidder about a product, for example. At this time, the bid application information about "goods A" is transmitted from the user terminal 15. FIG.

The host server 13, which has received the bid application information from the user terminal 15, once stores this bid application information in the database of the hard disk 23 in step S30. Then, in order to grant bonus points to the user in step S40, the hosting server 13 generates and transmits the random number generation processing screens 73 and 77 having the small screen of the bonus slot to the user terminal 15.

As a result, the display screen 73 as shown in FIG. 11 is displayed on the display of the user terminal 15. When the icon 75 of "by slot operation" is clicked on, it moves to the operation display screen 77 shown in FIG.

Here, the operation display screen 77 shown in FIG. 12 is demonstrated.

On the operation display screen 77, for example, a three-digit decimal number is displayed on the counter display unit 81 in advance. When the start button 79 is clicked by a user's operation, the counter display unit 81 is displayed. Each decimal digit in the number starts its own count. When an arbitrary display digit area is clicked, the counting operation is stopped and the numerical value at the time of the click is displayed.

First, when the user who visually checks the operation display screen 77 clicks the start button 79, the decimal number of each digit displayed on the counter display unit 81 starts counting independently. Here, the cursor is moved to an arbitrary display digit area and clicked to stop the counting operation, and the count of all the display digits is stopped in the same manner. Here, when the "send" icon 75 displayed on the operation display screen 77 is clicked, the user terminal 15 to the host server 13 as random number generation operation information including a 3-digit numerical value, for example. Is sent.

In step S50, the hosting server 13 receives random number generation operation information from the user terminal 15.

In step S60, the random number generation process is performed according to, for example, three-digit numerical values included in the random number generation operation information received from the user terminal 15, and a random number value that becomes an unpredictable number is calculated.

That is, for example, a random number value R having a 3-digit numerical value I as an input value is given by a known random number function.

(One)

In accordance with this, a random number value of an integer from 1 to I is obtained.

Other well-known methods can also be used for the algorithm of random number generation processing.

For example, the received 3-digit numerical value I is used as an input value as a random number value R.

R = I (2)

You may make it.

Next, the addition amount is calculated as follows.

Here, if the condition for the relationship between the bid price (N) and the addition amount (K) is obtained from the actual price (J), minimum bid price (Nmin), bid price (N), and addition amount (K) of the product,

Nmin ≤ N + K ≤ J (3)

When the range of addition amount K is obtained,

0 ≤ K ≤ J-N (4)

It becomes Here, the equation for calculating the addition amount K by adding the random number value R,

K = R * (1/1000) * α * (J-N)

0.01 ≤ α ≤ 0.9 (5)

Shall be. Α is the grant rate given by the auction company, and can be given any number.

Then, for example, in the three-digit numerical value (I) that received the addition amount (K),

K = I (6)

You may make it.

Next, the addition amount K calculated as described above in step S70 is transmitted to the user terminal 15.

Next, in step S80, the final bid price is obtained by adding the bid price received in step S30 to the addition amount K to make the final bid price of the user, and the final bid price is transmitted to the user terminal 15.

As a result, the bonus point (additional amount K) is displayed on the operation display screen 77 shown in FIG. 12 on the display of the user terminal 15. When the icon 83 of "send" is clicked here, the display screen 85 as shown in FIG. 13 is displayed.

As shown in FIG. 13, the display screen 85 adds a user's name, a brand name (goods A), the actual price of the goods A, the bid price of the goods A by the user, and the like. Icon 87 is displayed.

When the display screen 85 is visually confirmed by the user and the "confirmation" icon 87 is clicked on, the final bid price registration information is transmitted from the user terminal 15 to the hosting server 13.

In step S90, the host server 13 that receives the final bid price registration information from the user terminal 15 stores the final bid price of the user in a database and registers it.

In step S100, for example, when the holding period has elapsed, the hosting server 13 performs a successful bid process. Here, the host server 13 reads all the final bid prices of the goods A after the holding period from the database installed in the server 13, and selects the upper bid price by the number of items in the final bid prices. The names of the winners will be saved in the winner table. The names of the winners are also stored in the winners table. When there are a plurality of successful bidders having the same amount of money, the successful bidding is performed in the order of the quickest bidding time.

The names of the winners and the successful bidders are read from the winner table and the winners table, respectively, and an e-mail containing the winner notification information for the winners and the winner notification information for the winners is created and sent to the e-mail address of the member registered in advance.

As a result, as shown in FIG. 14, a display screen 89 is displayed on the display of the user terminal 15, so that the user wins the prize A, the successful bid price, the paid price, the payment method, the number of payments, The payment terms such as monthly amount and interest rate are displayed. When the icon 91 of "confirmation" is clicked here, winning confirmation information (not shown) is transmitted to the hosting server 13.

In step S110, the host server 13 that has received the winning confirmation information from the user terminal 15 stores the winning confirmation information from the user in a database, and adds the amount of money added to the payment institution as the price of the goods A. Generate payment request information for requesting payment of the excluded bid price (payment price). The host server 13 transmits this payment request information to the payment institution server 17.

The payment institution server 17 which received the payment request information from the host server 13 transfers the payment for this product A from the user's account to the auction company's account on behalf of the user.

In this way, the host server 13 displays the bid content of the product on the homepage, prompts the bidder's user terminal to input the bid price of the product, receives the bid price of the product from the bidder's user terminal, and then bidder's user. The terminal prompts the terminal to operate on the random number generation process, generates a random number according to the operation information received from the bidder's user terminal, calculates the added amount according to the random number, and adds the calculated amount to the bid price input when the auction is performed. The sum which adds and registers the added total amount as a final bidding price, performs a successful bid process in order of high bidding price among bidders, and the bidder contracts the payment request of the payment amount except the addition amount from a bidding price at the time of successful bid Because it sends to the payment institution server of the institution, the input to the presented operation screen The addition amount can be calculated from the unpredictable number resulting from the slot operation of the child, and the bidding amount can be added to the bidding price, and the bidding price is paid to the auction company without the addition amount from the bidding price. Therefore, since a bidder obtains the addition amount, it can contribute to the improvement of the bidder's participation motivation.

(2nd Example)

The configuration of the auction system according to the second embodiment of the present invention is applied to the system shown in FIG. 1 and the host server 13 shown in FIG. 2 as in the first embodiment.

Next, with reference to the flowchart shown in FIG. 15 and the sequence diagram shown in FIG. 16, the operation | movement of the host server 13 is demonstrated. The flowchart shown in FIG. 15 is operated by the control unit 29 in accordance with the control program stored in the hard disk HD installed in the hosting server 13.

The feature of the present embodiment is that instead of step S20 of the flowchart shown in FIG. 3, step S210 is used as shown in FIG. 15, and S220 is inserted between steps S30 and S40.

That is, the host server 13 that receives the product information request from the user terminal 15 searches for and reads the product information related to the “notebook” from the database stored in the hard disk 23 in step S210, and reads the “notebook”. Generate a page for presenting the content of the bidding, and transmit it to the user terminal 15.

In addition, in FIG. 17, in addition to actual price, a limited number, and a minimum bid price, the bid application fee etc. are displayed about goods A-D of each manufacturer regarding "notebook." When the icon 51 of "goods A" is clicked here, the display color of the selection display button 53 is reversed, and it shifts to the next display screen 95 shown in FIG.

Fig. 18 shows the actual price, minimum bid price, limited number, and one time of the product A in addition to information on the product A of the laptop, product description, product introduction, and after-sales service of the store. Information such as bid application fee is displayed.

When the icon 57 of "bid now !!" is clicked, the display color of the selection display button 59 is reversed, and the flow moves to the next display screen 61 shown in FIG.

In FIG. 19, a password input area 65 and a bid are provided in addition to the photograph about the product A of the "notebook" selected by the user, the actual price of the product, the minimum bid price, a limited number, and a single bid application fee. The "cash batch" area 67, the "installation" area 69, and the "slot bonus" icon 71 are displayed as a price input area 63 and a payment method. The password is an authentication number unique to each user given from the host server at the time of user registration. Here, the password will be described as having been previously given from the host server.

Here, the password mentioned above is input into the password input area 65 as bid application information by user's operation, and then a bid price is input into the bid price input area 63, and also "cash batch" or " When installment "is input and the" to slot bonus "icon 71 is clicked, it moves to the next display screen 73 shown in FIG. And it accepts acceptance of up to 3 bids, for example from the same bidder about a product. At this time, the bid application information about "goods A" is transmitted from the user terminal 15. FIG.

In step S220, the host server 13 that has received the bid request information from the user terminal 15 stores the bid request information from the user in a database, and requests the payment institution to pay one bid request fee. Generate fee deposit request information The host server 13 transmits this fee deposit request information to the payment institution server 17.

The payment institution server 17 which received the fee deposit request information from the host server 13 transfers this one-time bid fee from the user's account to the auction company's account on behalf of the user.

Hereinafter, since the processing content of each step after step S40 is the same as that described in the first embodiment, the description thereof is omitted.

As such, the hosting server 13 displays the bid contents and the bidding fee regarding the product on the homepage, prompts the bidder's user terminal to input the bid price of the product, and receives the bid price of the product from the bidder's user terminal. When a bid price for a product is input from a bidder's user terminal, the payment institution to which the bidder subscribes requests payment of a bid application fee to the auction organizer's account, and the bidder's user terminal performs operations related to random number generation processing. Prompts to generate a random number according to the operation information received from the bidder's user terminal, calculates the addition amount according to the random number, adds the calculated addition amount to the bid price input when the auction is performed, and adds the total amount added to the final price. We register as bid price and win in order that bid price is high among bidders And a request for payment of the payment amount excluding the added amount from the bid price to the payment institution server of the payment institution contracted by the bidder at the time of the successful bidding, and thus the prediction generated by the bidder's slot operation on the presented operation screen. Since the addition amount can be calculated from the impossible number and the bidding amount can be added to the bidding price, and the bidder pays the auction company a payment amount excluding the addition amount from the bidding price. It can contribute to the improvement of the bidder's motivation to participate.

(Third Embodiment)

Here, the cursor is moved to an arbitrary display digit area and clicked to stop the counting operation, and the count of all the display digits is stopped in the same manner. When the "send" icon 83 displayed on the operation display screen 203 is clicked here, for example, the user terminal 15 to the host server 13 as random number generation operation information including a 3-digit numerical value. Is sent.

In step S750, the host server 13 receives random number generation operation information from the user terminal 15.

In step S760, the random number generation process is performed according to, for example, the three-digit value included in the random number generation operation information received from the user terminal 15, and a random number value that becomes an unpredictable number is calculated.

That is, for example, a random number value R having a 3-digit numerical value I as an input value is given by a known random number function.

(7)

In accordance with this, a random number value of an integer from 1 to I is obtained.

Other well-known methods can also be used for the algorithm of random number generation processing.

For example, the received 3-digit numerical value I is used as an input value as a random number R,

R = I (8)

You may make it.

Next, the subtraction amount is calculated as follows.

Here, if the condition for the relationship between the bid price (N) and the subtracted amount (K) is obtained from the actual price (J), the lowest bid price (Nmin), the bid price (N), and the reduced amount (K) of the product,

Nmin ≤ N-K ≤ J (9)

If the range of the subtraction amount K is obtained,

| K | ≤J-N (10)

Becomes Here, the formula for subtracting the amount (K) by adding the random number (R),

K = R * (1/1000) * α * (J-N)

0.01 ≤ α ≤ 0.9 (11)

Shall be. Α is the grant rate given by the auction company and can be given any number.

Then, for example, when the subtracted amount K is received, for example, in the three-digit numerical value I,

K = I (12)

You may make it.

Next, in step S770, the subtracted amount K calculated as described above is transmitted to the user terminal 15.

Next, in step S780, the subtracted amount K is subtracted from the bid price received in step S30 to be the user's payment amount, and the payment amount is transmitted to the user terminal 15.

As a result, a bonus point (subtracted amount K) is displayed on the operation display screen 203 shown in FIG. 35 on the display of the user terminal 15, and this bonus point (subtracted amount K) is added from the registered bid price. The amount of payment resulting from subtracting) is displayed. When the icon 83 of "send" is clicked here, the display screen 205 as shown in FIG. 36 is displayed.
