Description

  The present invention relates to a net auction system, and more particularly to a net auction system that makes an inquiry about the identity of exhibitors and successful bidders via the Internet.

  In recent years, with the spread of the Internet, Internet auctions are actively held on the Internet. Unlike conventional auctions, this online auction is used by many users because it can be displayed easily even at a low price. Also, in online auctions, exhibitors and successful bidders buy and sell directly without intermediaries such as second-hand bookstores and antique dealers, so there are great economic advantages for both.

  However, while Internet auctions can be easily participated, the anonymity inherent to the Internet makes it difficult to understand the identity of the other party of the transaction, resulting in problems such as failure to receive the exhibit or payment of the winning bid. There are many.

One of the methods for preventing such troubles in the Internet auction is to use an escrow service.
This escrow service is a third party organization other than the successful bidder and exhibitor. The escrow service provider (hereinafter referred to as the escrow company) collects and pays the winning bid, so that the exhibit is not sent. And troubles such as unpaid bids.

As such an escrow service, an escrow system, an escrow method, and an escrow program disclosed in Patent Document 1 have been proposed.
The escrow system disclosed in Patent Document 1 provides an escrow service as follows. When a successful bid for an exhibit is determined, the server of this system sends an invoice for the winning bid to the winning bidder's terminal. When the server confirms that the winning bid has been deposited at the escrow company, the server transmits a notification prompting the shipment of the exhibit to the exhibitor terminal. Thereafter, when the server receives a notice of receipt of the exhibit from the successful bidder terminal, the escrow company pays the successful bid to the exhibitor.
In Patent Document 1, as described above, the server executes the process related to the escrow service, so that troubles between the exhibitor and the successful bidder can be avoided in the sale of the exhibit.
JP 2002-259873 A

However, in the escrow system as shown in Patent Document 1, the following problems occur.
As a problem on the side of the winning bidder, there is a problem that a complicated procedure such as visiting a bank or the like and paying the winning bid has to be performed as in the case of the conventional net auction. This leads to a delay in the payment of the winning bid and causes the sale of the exhibit not to be smoothly performed.
Further, as a problem on the exhibitor side, a delay in receiving time is caused as it is due to a delay in payment of the winning bid. Also, even if the winning bid is paid smoothly, the winning bidder will not receive the winning bid unless the server receives a notification that the item has been received, so the winning bidder will send the notification. If there is a delay, the exhibitor will also be delayed in receiving the winning bid as it is.
In addition, for escrow companies, due to such delays in the procedures of successful bidders and sellers, there will be a large amount of unfinished transaction transactions that need to be managed for a long period of time, hindering the efficiency of business processing. The problem of causing

  The present invention has been made in view of the above problems, and prevents troubles between exhibitors and successful bidders in an online auction, simplifies the procedure after a successful bid is made, and realizes smooth payment of the winning bid. The purpose is to provide an online auction system.

A network auction system in which an authentication server that authenticates at the time of an exhibition or a bid is connected to each other via a network. The authentication server receives a credit service subscription request from an exhibition terminal or a bid terminal. When the management server receives data on a seller or a bidder from a seller terminal or a bid terminal, the management server inquires the authentication server for authentication of the seller or the bidder. In the case of success, it is characterized by proceeding with an exhibition or bidding process.

  In addition, according to the net auction system of the present invention, the aforementioned bidding terminal inputs the card number issued at the time of joining the credit service and transmits it to the authentication server to perform the credit card settlement of the auction successful bid amount. To do.

  According to the network auction system of the present invention, when the bid terminal requests the management server to participate in the network auction, the screen information for the auction bid is received and displayed from the management server and displayed. On the screen, there is a character imitating the organizer and the bidder, the current highest bid amount, and an icon that sets the bid amount by adding a certain amount to the highest bid amount for each click. Features.

  According to the network auction system of the present invention, the management server described above is characterized in that when receiving an exhibition or bid request from an exhibition terminal or a bid terminal, authentication is performed using a digital signature.

These terminals and servers are connected to each other via a network such as the Internet.

  The exhibition terminal 1 is an information processing apparatus that can be connected to a network operated by an auction exhibitor (for example, a general-purpose PC or a mobile phone). The exhibitor operates the exhibition terminal 1 to access the Web page for auction, and registers the exhibit to be provided to the auction.

  The bidding terminal 2 is an information processing apparatus that can be connected to a network operated by an auction bidder (for example, a general-purpose PC or a mobile phone). The bidder operates the bidding terminal 2 to access the Web page for auction, and designates an item for which bidding is desired.

The management server 3 is an information processing apparatus managed by the organizer (for example, a workstation). The management server 3 has a function as a Web server that publishes an auction Web page on the Internet.
Further, the management server 3 has a function of issuing a public key or a secret key and authenticating the data received from the exhibition terminal 1 or the bid terminal 2 with a digital signature.
In addition, the management server 3 includes a database 31 for accumulating data related to auctions. The database 31 includes personal data of the exhibitor or bidder (name, address, presence / absence of auction / bid / successful bid, etc.), Management data (articles, exhibitors, bidders, current status, etc.) of the exhibits are managed.

The authentication server 4 is an information processing apparatus (for example, a workstation) managed by a credit sales company for authenticating exhibitors and bidders.
The authentication server 4 is provided with a database 41 for storing data of members of credit services provided by the credit sales company. In this database 41, personal data of exhibitors or bidders who have joined the credit service ( Name, address, card number, credit limit, history of screening at the time of membership, etc.) are managed.
The authentication server 4 can ensure the transparency of the auction participants by authenticating the exhibitors or bidders participating in the online auction.
The authentication server 4 also has a function as a Web server that publishes a credit service membership and authentication Web page on the Internet.

(Operation of the first embodiment)
2 to 4 are sequence charts showing the flow of operation by the net auction system in the first embodiment of the present invention.
Hereinafter, according to these drawings, each operation of (1) exhibitor or bidder registration operation, (2) exhibitor exhibit registration operation, and (3) bidder exhibitor bid operation in the present embodiment. Will be explained step by step.

(1) Registering operation of exhibitor or bidder First, the exhibitor or bidder subscribes to a credit service of a credit sales company and registers as a member before participating in the online auction. Hereinafter, this registration process will be described.

First, an exhibitor or a bidder accesses the authentication server 4 using the terminals 1 and 2, respectively (step S101), downloads a credit service membership Web page (step S102), and displays it on the screen. (Step S103).
The exhibitor or bidder uses the terminals 1 and 2 respectively to enter the necessary information for membership in the entry field on the membership page, along with the information that he / she wishes to join the credit service. It transmits to the authentication server 4 (step S104).
Here, the items necessary for membership are, for example, the name, address, gender, telephone number, e-mail address, etc. of the exhibitor or bidder, and are not limited thereto.

Upon receiving the input content, authentication server 4 displays the content (step S105). Based on the contents, the credit sales company will collect the exhibitor's or bidder's documents by mail etc. if necessary, and examine the membership.
As a result of the examination, if the credit sales company permits the participation of the exhibitor or bidder, the authentication server 4 issues authentication data (ID, password, card number, etc.) of the exhibitor or bidder, and this authentication data At the same time, the personal data of the exhibitor or bidder is registered in the database 41 (step S106).
Then, the authentication server 4 transmits the issued authentication data and a notification indicating that the membership has been permitted to the terminals 1 and 2 of the exhibitor or bidder who has permitted the membership (step S107).

In this way, the exhibitor side or the bidder side receives the entrance examination by the credit sales company in advance before participating in the auction, and uses the authentication data issued as a result of the examination at the time of participation in the auction. Can be held.
Further, when making a successful bid, it is possible to make a centralized and easy payment of the winning bid by using the subscribed credit service.

(2) Exhibitor's exhibit registration operation After the registration for the credit service is completed, the exhibitor uses the exhibit terminal 1 to access the management server 3 when exhibiting an exhibit, and the ID, password, A name and the like are input and transmitted to the management server 3 (step S201).
When the management server 3 receives the seller's ID / password, the management server 3 transmits the received ID / password to the authentication server 4 to request authentication of the seller (step S202).
When the authentication server 4 receives the ID / password, the authentication server 4 compares the received ID / password combination with the ID / password combination in the database 41. If the authentication is unsuccessful (step S203), the authentication result of the seller is returned to the management server 3 (step S204).

  The management server 3 receives the seller authentication result from the authentication server 4, and if the result is an authentication failure (step S205 / No), the management server 3 transmits a notification to that effect to the exhibition terminal 1 (step S206). The organizer will cancel the subsequent listing procedure.

On the other hand, when the management server 3 receives the authentication result indicating that the authentication is successful (step S205 / Yes), the management server 3 transmits a Web page for exhibit registration to the exhibition terminal 1 together with a notification to that effect (step S207).
When the exhibition terminal 1 receives the Web page for exhibit registration from the management server 3 together with the notification that the authentication is successful, the exhibition terminal 1 displays the Web page (step S208).
The exhibitor uses the exhibition terminal 1 to input items (exhibition conditions) such as the article name, desired price, and bid closing time of the exhibit to be exhibited this time in the input fields on the exhibit registration Web page. The input contents (hereinafter referred to as exhibition data) are transmitted to the management server 3 (step S209).
When receiving the exhibition data, the management server 3 registers the reception information in the database 31 (step S210).
Thereafter, the management server 3 publishes the registered contents on the auction Web page (step S211), and accepts the auction participation of the exhibit on the Web.

  In this way, when an exhibitor exhibits an exhibit, authentication is performed using highly reliable authentication data issued by the authentication server 4 on the credit sales company side, so the identity of the exhibitor is clarified, It is possible to easily prevent fraud.

(3) Bidding operation of the bidder After the registration for the credit service is completed, the bidder can participate in the bidding of the items for the online auction.
As in the case of the seller, the bidder logs in with the ID / password using the bid terminal 2 and, if the authentication is successful, can receive and display the auction Web page from the management server 3 ( Step S301). Since the bidder authentication method is the same as that of the exhibitor, the description is omitted.
The bidder uses the bidding terminal 2 to specify the item to be bid from the list of items displayed on the Web page and input the bid amount. Then, the bid terminal 2 transmits the specified exhibit and bid price information (hereinafter referred to as bid data) to the management server 3 (step S302).

  When receiving the bid data, the management server 3 stores the bid data in the database 31 and additionally reflects the stored contents on the auction Web page (step S303).

Thereafter, when the management server 3 confirms that the bid deadline for the exhibit has been reached (step S304 / Yes), the management server 3 stops the subsequent bidding for the exhibit (step S305).
The management server 3 designates the bidder who entered the highest bid amount when the bidding is stopped as a successful bidder, and sends a notification to the effect that the successful bid has been made (hereinafter referred to as a successful bid notification) to the bidder 2 of the successful bidder. (Step S306).

Upon receiving the successful bid notification, the successful bidder's bidding terminal 2 accesses the management server 3 (step S307), downloads an authentication page for credit settlement (step S308), and downloads this authentication page. It is displayed (step S309).
The winning bidder uses the bidding terminal 2 to enter the name of the credit service holder, the card number, etc. in the input field on the authentication web page, and with this input information, the winning bid data (successful bid product name, winning bid price). Etc.) to the management server 3 (step S310).

  When receiving the input information and successful bid data, the management server 3 transmits the input information and the successful bid amount to the authentication server 4 and requests credit settlement of the successful bid amount (step S311).

  Upon receiving the input information and successful bid data, the authentication server 4 collates the received combination of the name and card number with the combination of the name and card number in the database 41 (step S312).

If the two do not match (step S312 / No), the authentication server 4 transmits the authentication result (failure) to the management server 3 (step S317).
When the management server 3 receives this authentication result (failure), the management server 3 transmits a notification to the bid terminal 2 to prompt the input of the name of the holder and the card number again (step S318).

On the other hand, if the two match (step S312 / Yes), the authentication server 4 determines that the authentication is successful, accesses a server (not shown) of a financial institution such as a bank, checks the balance, and then makes a winning bid. Credit settlement processing is performed (step S313).
Then, after the credit settlement process is completed, information indicating that the credit settlement has been completed (hereinafter referred to as settlement completion information) is transmitted to the exhibition terminal 1 and the bid terminal 2 via the management server 3 (steps S314 to S316).

When the bid terminal 2 receives the payment completion information, the bid terminal 2 displays on the screen that the payment has been completed, and the successful bidder confirms that fact.
On the other hand, when receiving the settlement completion information, the exhibition terminal 1 also displays on the screen that the settlement has been completed. When the exhibitor confirms the completion of the settlement, the exhibitor performs work such as shipping the exhibit.
After that, the exhibitor receives the settlement amount (successful bid amount), but the organizer receives a part of it as a fee (brokerage fee).

In this way, the exhibitor and the successful bidder, when joining the credit service of the credit sales company, make an identity inquiry in advance and then register the authentication by the authentication server 4. By authenticating with the server 4, the problem of anonymity peculiar to the Internet can be solved, and fraud in the online auction such as non-payment of the winning bid, delay in payment, undelivered items and delay in shipment can be easily prevented. It becomes.
Further, since the authentication server 4 of the credit sales company performs automatic settlement processing of the winning bid in addition to the above-described authentication processing, it is possible to prevent the occurrence of troubles such as delay or non-payment of the winning bid in the online auction. Become.
Thus, as a result of exhibitors or bidders being able to participate in the online auction with peace of mind, the organizer can also gather a large number of participants.

(4) Digital signature processing at the time of listing or bidding In this embodiment, digital signature technology is used to prevent impersonation of exhibitors or bidders.
FIG. 5 is a sequence chart showing the flow of digital signature processing by the net auction system in the present embodiment.
Hereinafter, the digital signature process according to the present embodiment will be described with reference to FIG.

  First, when the credit sales company permits the participation of exhibitors or bidders, the management server 3 creates an individual secret key for each exhibitor or for each bidder (step S401), and the created individual secret key for each participant. Is transmitted to the exhibition terminal 1 or the bid terminal 2 (step S402).

Upon receiving the secret key, the exhibition terminal 1 or the bid terminal 2 stores the received secret key (step S403).
Thereafter, at the time of listing or bidding, the listing terminal 1 or the bid terminal 2 creates a message digest using the hash function from the listing data or bid data transmitted to the management server 3 (step S404).
Next, the exhibition terminal 1 or the bidding terminal 2 encrypts the created message digest with a secret key and creates a digital signature (step S405).
Then, the exhibition terminal 1 or the bid terminal 2 transmits a digital signature to the management server 3 together with the exhibition data or the bid data at the time of exhibition or bidding (step S406).

When the management server 3 receives the digital signature together with the exhibition data or bid data, the management server 3 creates a message digest from the received exhibition data or bid data using a hash function (step S407).
Next, the management server 3 decrypts the received digital signature into a message digest using the public key (step S408).
Then, the management server 3 compares the decrypted message digest with the message digest created by itself in step S407 (step S409).
Here, when both digests match (step S409 / Yes), the management server 3 determines that the digital signature has been successfully authenticated, and accepts an exhibition or a bid based on the received exhibition data or bid data (step S410).
On the other hand, if the two digests do not match (step S409 / No), the management server 3 determines that the digital signature authentication has failed, and does not accept the received exhibition or bid based on the received exhibition data or bid data (step S409). S411).

  As described above, when the management server 3 receives the exhibition data or the bid data, it authenticates using the digital signature received together with the exhibition data or the bid data. Therefore, a malicious third party exploits the anonymity specific to the Internet. It is possible to prevent unauthorized participation in the auction. Further, it becomes possible to prevent the malicious third party from participating in the auction while pretending to be an exhibitor or a bidder.

As a method for presenting the bid amount, for example, the highest bid amount is directly input.
As another method, when a button or icon on the screen is clicked, a predetermined amount (for example, 100 yen) can be bid for an amount exceeding the current maximum amount. In this case, the bidder can easily present the highest bid by simply clicking a button or the like.

In addition, characters corresponding to bidders participating in the exhibit are displayed on the screen. Each time the bidder presents the bid amount, the color of the character corresponding to the bidder changes or an animation operation is performed.
In principle, all bidders who bid are displayed as characters on the screen, but the bidder's character who has not bid for a certain period of time may be automatically deleted from the screen.

  In addition, a character imitating the organizer is displayed on the screen. When making a successful bid, an animation operation is performed in which the organizer's character strikes a hammer.

  In this way, by changing each character or performing a specific action according to a bid or a successful bid, it is possible to make the current situation of the auction easier to understand for the participants and to make them familiar, As a result, it becomes possible to provide a unique sense of presence, and as a result, it is possible to expect a further increase in the number of participants.
