Description

Probability auction system and method therefor}

The present invention relates to an internet auction, and more particularly, a bid is received in a unit of won between the preset highest bid and the lowest bid for each item to be auctioned, and after the bid is completed, the bidders directly After a successful bid adjustment time is set so that the bid can be adjusted to match the bid, it is related to the probability auction of selecting bidders who have bids that match or closest to the successful bid price at the end of the successful bid price adjustment time.

In general, the auction method through the Internet is a seller-oriented auction method in which the seller discloses information on the goods, the bid price, the auction closing date, etc., and the buyer first bids on the purchase price through the bidding, and the consumer first presents the value of the product. It is implemented as a reverse auction method that allows the goods of suppliers who accept this purchase condition to be purchased.

However, the internet auction method of this type is biased toward sellers or buyers, so either side can lose money.

The seller-oriented auction method allows multiple buyers to compete so that only the buyer who bids at the highest price among the bidding bids can win the bid. The winning bid price of the goods goes up. Therefore, in the case of a popular item, it may be possible to purchase the corresponding item at a relatively high price due to excessive competition with other purchasers.

In the reverse auction method, the seller who offers the lowest price wins the bid without ignoring the quality of the product that the buyer wants to purchase. I have a hard time. In addition, the seller also has to sell the goods at the lowest price, there is a problem such as loss of honor due to economic loss or supply of low-quality products.

Recently, there is a lottery auction method in which a designated bid is paid according to the goods sold and a lottery number is given. However, if the goods are expensive, a high bid must be made, which can be economically burdensome. In addition to lowering the auction participation rate by fostering anxiety, the auction participation rate was low, and the auction period was long, or the bidding was delayed, which lowered the interests of the participants and hampered the activation of the internet auction.

In another Internet auction method, when a buyer bids at an arbitrary amount between the highest price and the lowest price of the auction item, the buyer who presents the highest amount among the buyers who has provided the non-overlapping bid amount among the bidding prices The bid is to be won. In such an auction, the buyer must use the coupon every time he bids, and because the buyer does not limit the number of bids, buyers must offer a lot of bids that are not expected to be offered by other buyers in order to increase the probability of winning a bid. Therefore, the cost burden is increased because a lot of coupons must be used, and in the case of a popular item, when a lot of bidders make a lot of bids, the amount of overlap is increased and the possibility of a successful bidder is lowered.

Therefore, an object of the present invention for solving the above-mentioned problems is to increase the fairness by allowing bidders to bid the amount desired by the unit of won between the highest bid and the lowest bid in units of one won, and to allow the bidder to adjust the successful bid price for a certain period of time after the bid is closed It is to increase the fun of the auction and to be able to purchase the desired item at a low price.

Probability auction system of the present invention for achieving the above object is a plurality of bidder terminals for transmitting the bid input by the bidder over the Internet, and transmits the successful bid price adjustment value after the preset bidding time; And the bidder who receives the bid during the bidding time, adjusts the bidding price according to the bidding price adjustment value received from the bidder terminals during the bidding price adjustment time after the bidding time is closed, and sends the bidder that matches or closest to the bidder adjusted at the end of the bidding price adjustment time. And a probability auction device for determining a successful bidder.

The probability auction method includes a first step of presenting auction information including the highest bid price, the lowest bid price, and the successful bid price for the auction target item; A second step of receiving bids for the auction target item during a preset bidding progress time; A third step of, if the bidding progress time elapses, receiving an adjustment value for adjusting the successful bid price during a preset successful bid price adjustment time and adjusting the successful bid price according to the received adjusted value; And at the end of the successful bid price adjustment time, determining a successful bidder according to the finally adjusted bid price and bid.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the overall configuration of a probability auction system according to the present invention.

The bidder terminal 100 is a device that can be connected to the probability auction device 200 through a wired / wireless internet, and may be a personal computer, a notebook computer, a wireless internet phone, or an interactive digital TV.

The probability auction device 200 is a bidder terminal 100 connected through the Internet, and provides auction auction progress information and product information on the auction target product according to the present invention, and when the auction starts, auction for a predetermined bid time The bidder for the desired item is received from the bidder terminals 200 for the target item. In this case, the bid may be bidding by the unit of one won in the amount between the highest bid and the minimum bid determined for each auction object, and can not bid for the same amount overlap. That is, only one person can bid on one bid. When the bidding time has elapsed, the probability auction device 200 provides a bidding price adjustment time that allows the bidder to directly adjust the bidding price of the corresponding item for a predetermined time. When the successful bid price adjustment time is completed, the probability auction device 200 determines a bidder who matches the successful bid price immediately after the successful bid price adjustment time is completed or presents the bid closest to the successful bid price, and provides the bid price adjustment details to the bidders. do.

2 is a view showing in more detail the configuration of the probability auction device according to the present invention.

The probability auction device 200 of the present invention includes a data management module 210, a progress module 220, and an analysis module 230.

The data management module 210 collectively manages all data necessary for the auction such as auction bidder information, payment related information, bidding information, and successful bid adjustment value. The information of the data management module 210 is appropriately called and used in all modules requiring input / output of data.

The data management module 210 includes three data storage groups, namely, auction item information DB 212, bid information DB 214, and adjustment value information DB 216.

The auction article information DB 212 stores information about auction target items. That is, information about the name, model name, detailed description, manufacturer, product picture, auction start and closing time, market price, highest bid and minimum bid, bid price, total number of participations, maximum number of participations per person, etc. are stored. . The bidding information DB 214 stores bidders' bidding information for the auction items. That is, information such as the auction item unique code, bid time, bidder ID, bid amount, the first successful bid adjustment value is stored. The adjustment value information DB 216 stores all adjustment details adjusted at the successful bid adjustment time. That is, the auction item unique code, adjustment time, adjuster ID, adjustment value and the like are stored. The storage space for storing such data can be allocated separately for each item to maximize the data processing speed and efficiency of the adjustment value information of the successful bid adjustment time, which can generate a large amount of traffic, especially when the auction proceeds.

The progress module 220 displays the auction target items in a virtual (cyber) space, updates the current status of the auction target items, auctions such as screen output layouts according to each auction progress status, bidding and auction price adjustment of auctions. Manage your progress.

The analysis module 230 receives all data on the auction from the data management module 210, aggregates and analyzes the data, and displays the result. That is, the auction status provided at the time of auction and the auction result data such as the auction result provided at the end of the auction are aggregated and analyzed so that the bidders can know the result.

The analysis module 230 verifies the integrity of the data provided from the data management module 210 prior to data analysis and display.

3 is a flowchart illustrating a method of verifying data integrity in the analysis module 230.

The analysis module 230 collects data necessary from the data management module 210 for data analysis on the specific auction item (step 310).

Once data collection is complete, an integrity check on the data begins (step 320). The analysis module 230 first checks whether the unique value of the auction item and the corresponding value of the data collected for the item in step 310 coincide with each other (step 320).

If the two values do not coincide with each other, the current data is deleted and the data management module 230 collects information on the item again (step 330). However, if the two values coincide with each other, then it is checked whether the time value of the corresponding data has an incorrect time value or if there is data with a trace of manipulation (step 340). That is, it is checked whether the auction start time and the deadline time for the item are wrong or whether the data value has been manipulated and changed by someone. At this time, if there is a problem, as in step 330, the current data is deleted and information is collected again. If there is no error, the integrity check passes (step 350).

The analysis module 230 starts the analysis on the data only when the integrity check passes safely (step 360). The analysis module 230 announces the results to bidders who are accessing the probability auction device 200 through an internet site (web site or a wireless Internet site such as WAP) when the analysis is completed, and also sends the result to the progress module ( 220) (step 370).

However, performing the integrity check in the analysis module 230 instead of performing the data management module 210 may include separate processing in the data input or output process in order to optimize the data input / output speed of the data management module 210. The processing is to be omitted.

In addition, the analysis module 230 takes a lot of system load because it must analyze and display the bid details that are changed from time to time and the successful bid price adjustment details to be described later. Therefore, the data should be processed with the least amount of data and the smallest number of times, and with the least number of times. To this end, the analysis module 230 prevents redundant processing through the following method.

First, when announcing the bidding status, only the added part is reprocessed using the last status data and passed to the progress module 220. And secondly, when analyzing data for winner announcements, all data from the beginning to the end are re-analyzed to re-verify the integrity, which is only handled once and viewed by the bidder who is the first to see the winner. Save the details to a complete data file. Therefore, for the subsequent inquiry, the result of the process previously processed is transferred directly to the progress module 220 instead of through the analysis module 230, thereby avoiding an error of repeating the same task again, thereby preventing duplicate processing.

4 is a flowchart illustrating a process of proceeding a probabilistic auction using the probabilistic auction system having the above-described configuration, and the probabilistic auction method according to the present invention will be described in detail with reference to FIG. 4.

First, as a bidding scheduled step before the auction start, the probability auction device 200 discloses the auction progress related information through the Internet site in advance before the auction starts (in step 411). That is, each bidder terminal 100 that accesses information such as auction start time and deadline time, highest bid and minimum bid, total number of bids, detailed information on auction target items, bid points, and start bid price, etc. To inform bidders.

In this case, the highest bidding price is the highest amount that can be bid on the goods, and the highest bidding price is markedly discounted from the market price of the auction target product. Price discounts vary by product and the highest bid is priced from the highest 1/10000 to the lowest 1/3 of the market price. A bidder may not bid with an amount higher than the highest bid. The minimum bid price is the maximum bid price minus the total number of seats that can be bid on the item. A bidder may not bid with an amount lower than the minimum bid. The total number of seats that can be bid is the maximum bid minus the minimum bid, which is arbitrarily determined according to the price of the goods.

The bidding point is a participation fee that is reduced by a certain amount from the bidder's earned points each time the bidding bidder, and the bidder must have accumulated at least the bidding point or more points. These earned points can be earned by purchasing (charging) or purchasing goods in the probability auction device 200 by purchasing coupons, such as passbook payment, credit card payment. Bid points are not refundable except when the auction itself is cancelled.

These bid points are calculated by the following formula by the selling price, successful bid price, and total number of items.

Bid point = ((sales-winning bid) / total seats) × 2

During the auction planning stage, the people who want to participate in the bidding access their own bidder terminal 100 to the probability auction device 200, check the known information, check whether the desired item is in the auction item, and then select the desired item. Select.

If the bid start time has not yet reached (step 412), the bidder who selects the desired item waits until the known bid start time (step 413).

When the bid start time arrives, the auction starts automatically and the progress module 220 receives bids from bidders through the bidder terminals 100 (step 414).

In bidding, bidders can bid a desired amount in a unit of won between the highest bid and the lowest bid and the bidder can not bid for the same amount. In other words, only one person can bid for one amount of one-won unit, and the maximum number of bids (highest bid-minimum bid) that can bid for each item is determined. Therefore, the bidder must first check whether the desired bid is the bidable amount before bidding. In addition, the maximum number that can be bid per person is also determined for each item to ensure fairness of the auction.

When the bidders make a bid, the bidding module 220 subtracts bid points from the bidder's earned points for each bid, and gives the bidder one chance to adjust the successful bid price. The bidding price adjustment by the bidder is the biggest feature in the present invention, by subtracting or adding a certain number from the current bidding price to adjust the bidding price so that the changed bidding price can be matched with the bidding bid. For example, the bidder may accept any one of -3, -2, -1, 0, +1, +2, and +3 as the successful bid adjustment value, and the progress module 220 may proceed. The bid price adjustment value received from the current bid price is subtracted or added to update the bid price. A bidder who does not want to adjust the bid price may select "0" as the bid price adjustment value. The bidders are given a certain number of times (eg four times) of bid adjustment, one of which will be done at the time of bidding and the other three will be held for a certain time (eg, 24 hours) after the auction closes. The description of such successful bid adjustment will be described later in more detail.

The progress module 220 counts the number of bids for the commencement of the auction before the auction deadline to determine whether the number has reached the maximum number of bids for the commodity (step 415). Information about the bid is stored in the bid information DB 214, the analysis module 230 uses the bid information stored in the bid information DB 214 to start by updating the bid status in real time.

This progress update may be automatically executed once every 0 seconds or at the request of a bidder (clicking a predetermined icon).

If the number of bids has not yet reached the maximum number of bids, the progress module 220 checks whether the bid deadline has arrived (step 416).

If the bid deadline has not yet arrived, bid acceptance will continue until the bid deadline has reached or until the bidder has reached the total number of bids (maximum bid count) after the number of bids has reached or exceeded the minimum bid number ( Step 417). Here, the minimum number of bids is the minimum number of bids to be bid for each item in order to proceed with the auction. If the number of bids is less than this, the auction for the item is checked and the auction itself is cancelled. In this case, the bidding point is recharged with the earning points of the bidder and the item may be excluded from future auction items because the item is not popular. The minimum number of bids is appropriately determined according to the price of the goods, and the auction proceeds even when one person participates except in the case of expensive goods.

When the bid deadline arrives in step 416, it is checked whether the number of bids up to that time has exceeded the minimum bid number (step 418).

If the number of bids does not exceed the minimum number of bids, as described above, the auction for the article is canceled and the bid points of the bidders who have already bid are refunded (step 419).

However, if the bid is closed and the bid number reaches the minimum bid number, the bid price adjustment is started (step 420). In addition, even if the number of bids reaches the maximum number of bids before the bid deadline in step 415, the progress module 220 may not bid any more, so that the bidding is terminated regardless of the bid deadline and the bid price is adjusted.

For the successful bid price adjustment, the progress module 220 sets the successful bid price adjustment start time and the adjustment end time (step 421). In general, the bid price adjustment is performed for a period of time (eg, 24 hours) immediately after the auction closes, so the bid price adjustment time is equal to the auction deadline, but if the number of bids reaches the maximum bid number before the bid deadline in step 415, the bid price The adjustment time must be adjusted again. That is, if the auction ends at an indeterminate time, such as reaching the maximum number of bids, the majority of bidders are not aware of the fact, so the progress module 220 sets new bid adjustment start time and adjustment deadline after In step 421), the bidder is notified of the auction closing and the newly set bid price adjustment time through an e-mail or a short message service (SMS). The bidder information uses the information entered by the bidder during membership registration.

And, the bidding related information during the bidding is stored in the data management module 210, the analysis module 230 analyzes this information to continuously announce the bidding progress, and notifies the final bidding situation when the bidding is closed. do.

Next, the progress module 220 receives the successful bid price adjustment value from the bidders through the bidder terminal 100 when the successful bid price adjustment start time is reached (step 422).

5 is a conceptual diagram illustrating a successful bid adjustment according to the present invention.

For example, if the highest bid and lowest bid are $ 120,000 and $ 30,000, respectively, and the current bid price is $ 70,000, the first bidder who bids at $ 70,003 bids to match the bid price to his bid. By using the terminal 101 of the input successful bid adjustment value "3". Then, the current successful bid price is changed to 70,003 won and the first bidder becomes a successful bidder. The initial starting bid price for the item is arbitrarily set at 50% or less of the selling price, but the current bid price is continuously changed during the auction by one adjustment given at the time of bidding during the overall bid price adjustment opportunity as in step 414.

The bidder's winning price adjustment details (adjustment value, adjustment time, adjuster ID, current successful bidder, etc.) are stored in the adjustment value information DB 216 in real time, and the analysis module 230 uses the information to determine bidder adjustment status. Announce in real time through the Internet site so you can check.

Next, the second bidder who bids 70,001 won enters "-2" as the successful bid adjustment value using his terminal 102 to match the successful bidder currently being 70,003 won with his bid. Then, the progress module 220 changes the current successful bid price to 70,001 won and the second bidder to a successful bidder.

In this case, the bidder may select any one of -3, -2, -1, +1, +2, and +3 as a successful bid price adjustment value. Here, the difference between the successful bid price adjustment performed after the bidding is closed and the successful bid price adjustment performed at the bidding is that "0" cannot be selected as the successful bid price adjustment value after the bid is closed. In other words, the bidder must adjust the current bid price after the bid price is adjusted after the bid is closed. As described above, the range of the successful bid price adjustment value is set within a constant value range (-3 to +3). If the successful bid price adjustment value is not defined or is set too large, the successful bid price can be adjusted by one's own bid even with one adjustment. This is because bidders do not actively participate in the bid price adjustment and try to match the bid price with the bid by one adjustment at the time when the bid price adjustment time is almost over.

Of course, in the above-described embodiment, the successful bid adjustment value range is set to -3 to +3, but this range may be appropriately changed within a range that does not impair the gist of the present invention.

In this way, all bidders who participate in the bidding enter a bid adjustment value to match the bid price with their bid, so that the bid price continuously changes according to the most recently entered adjustment value. However, each bidder is not given an unlimited chance to adjust the winning price, but only a certain number of times, and one of them is used simultaneously with the bidding. Most importantly. In addition, even if the successful bid price adjustment does not use all of its adjustment opportunities, the remaining opportunities are automatically exhausted and the bid price adjustment is terminated. Thus, unlike the conventional auction method that passively waits for the result after the bidding, the probability auction of the present invention can participate in the auction so that the bidder can directly win the bidding like a game so that the user can enjoy the auction more funly. It is possible to exclude the possibility.

In the above-described embodiment, only two bidders are described to explain the successful bidder adjustment method, but in practice, a large number of bidders adjust the bidder frequently from time to time, and more bidders are bundled simultaneously as the bidder adjustment deadline is closer. As a result, the winning bid is adjusted. As a result, the winning bid may exceed the highest bid or fall below the minimum bid. In this case, if the winning bid exceeds the highest bid, the winning bid starts again at the lowest bid, and if the winning bid falls below the minimum bid, the winning bid starts again at the highest bid.

This successful bid adjustment is performed for 24 hours, and when the adjustment deadline is reached (step 424), the progress module 220 ends the successful bid price adjustment and receives no further adjustment value. The analysis module 230 calculates / aggregates / analyzes all data of the successful bid adjustments stored in the data management module 210 to generate result data (step 425).

The analysis module 230 organizes and publishes the generated result data and announces the winners (step 426). In other words, the total number of participants, total bid details, successful bid adjustments, etc. are displayed for the bidders to easily check and the final winners are announced. The final winning bidder becomes the bidder who bids at the same time as the successful bid adjustment deadline or at the latest adjusted bid price. Therefore, the final winner is determined at the same time as the successful bid adjustment deadline.

However, in the above-described embodiment, since bidding is possible between the highest bid and the lowest bid in a unit of one won and only one person can bid for one amount, the maximum number of bidders who can participate in the bidding is 90,000 (120,000-30,000). Becomes Thus, depending on the popularity of the article, the number of bidders may reach the maximum number of bidders, but may not. If the number of bidders does not reach the maximum number of bidders, it means that there is an amount that the bidders do not bid on, and that the adjusted bid price may match the amount that is not bidded.

In such a case, the item is awarded to the bidder who bids closest to the final bidder, and if two such bidders are present, to the bidder who bids the higher bid.

That is, in the probability auction method according to the present invention, a successful bidder is generated, and further, the successful bid amount does not exceed the highest bid price.

When the successful bidder is confirmed, the probability auction device 200 confirms the purchase intention and status of the successful bidder (step 427), and when the successful bidder pays the successful bid amount, delivers the item to the successful bidder's address (step 428). This ends the auction for the article.

The bid details and the bid price adjustment details may be transmitted to the bidders or e-mail of the desired bidders.

In the above-described embodiment, it is obvious that the successful bid adjustment time (24 hours), the maximum number of successful bid adjustments given to each bidder (4 times), the maximum number of bids per person, etc. can be adjusted according to the system operator. Other embodiments are possible without departing from the spirit of the invention.

As described above, the probability auction of the present invention allows bidding so that the same amount of money is not duplicated between the highest bid and the lowest bid in a unit of one won, and bidders are determined for a predetermined time after the closing of the bid without determining bidders using only bids. By allowing you to adjust the number of bids to match your bid, you can enjoy the auction more like a game. In addition, by setting the maximum number of bids for each item and the maximum number of bids per person for each item and make sure that the successful bidding is made between the highest bid and the lowest bid, it is possible to increase the fairness of the auction with the fairness of the auction.
