Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an auction system and method using a network such as the Internet, and more particularly, to an auction system and method for improving user convenience in an auction service.
[0002]
[Prior art]
With the rapid spread of the Internet in recent years, an online auction service has attracted attention as a service that supports transactions between online individuals, between a company and an individual, or between companies. In such an auction service, a user accesses an auction site where the service is provided from a user terminal such as a personal computer connected to the Internet, and offers an offer for sale (exhibition), an offer for purchase, and an item to be purchased. Can be easily bid. At the auction site, management of exhibition information, purchase information and bid information from users, provision of information to users, successful bid processing, etc. are performed, and results of successful bids are notified to successful bidders and sales or purchase offerers by e-mail etc. Is done.
[0003]
In such an online auction, the use of an e-mail address is an essential requirement as an address on the network. In particular, the existence of the other party is not confirmed on the Internet, and an e-mail address is used as a user specifying means. For example, in an online auction, registration of an e-mail address is requested in addition to a user name and address at the stage of user registration. After that, when admission is permitted in a certain admission procedure, an admission confirmation email is sent to the registered e-mail address as a verification procedure, and the user is requested to reply with the e-mail confirmation code given at the user registration stage. To do.
[0004]
In particular, in an online auction that allows use for an unspecified number of users, an e-mail address may be the only means of identifying users. Therefore, in such an online auction, it is common that only one e-mail address is registered for one user.
[0005]
[Problems to be solved by the invention]
By the way, the e-mail address registered for each user is used for a contact e-mail to the user necessary for providing the auction service. For example, a general contact email about auctions, a successful bid contact email to bidders, successful bidders, sales or purchase offerers at the end of bidding, right acquisition price to successful bidder who presented the right bid price For example, an email notifying you of the renewal (the highest price for a sale offer, the purchase offer for a purchase offer). In particular, by contacting the relevant users via e-mail, such as a successful bid contact mail or a right acquisition price update mail, the speed of the auction service is increased and the convenience of the service is increased.
[0006]
However, depending on the user, for example, a notification mail to an e-mail address set in a personal computer at home may not be accessible from a computer at work. Alternatively, a user on a long business trip may not be able to use his home computer and cannot read the notification mail from the business trip destination.
[0007]
Among various contact mails, general contact mails and successful bid failure mails for notifying successful bids are not so urgent e-mails. However, for example, the highest bid price update e-mail or successful bid e-mail notifying that a successful bid has been made, a new bid is made in response, a transaction between the winning bidder and the seller after the bidding is started, etc. It is necessary to take some action urgently, and it is desirable to establish a communication environment that does not depend on the mail access status of the user.
[0008]
SUMMARY OF THE INVENTION An object of the present invention is to provide an auction system and method for enabling a user to receive an emergency contact mail as quickly as possible in an auction service using a network.
[0009]
It is a further object of the present invention to provide an auction system and method for enabling a user to respond as quickly as possible to a contact mail that requires an emergency in an auction using a network.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, according to one aspect of the present invention, in a network-based auction system, in addition to a main e-mail address, a sub-e-mail address is added to a user database if the user desires. Enable registration. The first e-mail that does not require an urgent need for the auction service is transmitted to a main e-mail address, and the second e-mail that requires an urgent is transmitted to the main and sub-e-mail addresses.
[0011]
According to the above-described invention, a user who frequently uses a main e-mail address as a user-specific means and frequently has difficulty in accessing an urgent e-mail is desired by the user. Accordingly, the sub-e-mail address is registered, and an urgent e-mail can be transmitted to both the main and sub-e-mail addresses, so the convenience of the auction service can be improved. In addition, since an e-mail that does not require urgent is transmitted only to the main address, an increase in data communication traffic in the auction system can be minimized.
[0012]
In the above invention, in a more preferred embodiment, a right acquisition successful bid price update mail for notifying a successful bidder who has bid for the right acquisition successful bid price that the right has been transferred to another person and / or a successful bid is established. A successful bid notification mail for notifying successful bidders and exhibitors of the fact is sent to both the main and sub e-mail addresses, and other mail related to the auction service is sent to the main e-mail address.
[0013]
In the second aspect of the present invention, the second e-mail for the main e-mail address and the second e-mail address for the sub-e-mail address are different contents corresponding to the respective e-mail addresses. It is characterized by having. That is, the auction system creates separate second e-mails each having optimum content according to the environment in which the main and sub e-mail addresses can be received, and transmits the second e-mails to the corresponding e-mail addresses. Thereby, the user can receive the second e-mail corresponding to the received environment, and can take a necessary action in the received environment.
[0014]
In the second aspect described above, in a more preferred embodiment, the URL address in the auction site that prompts access to the re-bidding screen is included in the right acquisition price update mail that is an example of the second electronic mail. The URL address is the address of an HTML document suitable for the environment where the main e-mail is received in the case of the main e-mail, and the sub e-mail is received in the case of the sub-address e-mail. The address of another HTML document suitable for the environment. Thereby, in the environment where the e-mail of each address is received, it is possible to access and display the immediate re-bidding screen and perform a re-bidding.
[0015]
In the above second aspect, in another preferred embodiment, a successful bid establishment mail, which is an example of the second electronic mail, is urged to access a contact navigation screen between the sales or purchase offerer after the successful bid and the successful bidder. Include the URL address in the auction site. The URL address is the address of an HTML document suitable for the environment where the main e-mail is received in the case of the main e-mail, and the sub e-mail is received in the case of the sub-address e-mail. The address of another HTML document suitable for the environment. Thereby, in the environment where the e-mails of the respective addresses are received, if desired, it is possible to access the instant contact navigation screen and start contact after a successful bid.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. However, such an embodiment does not limit the technical scope of the present invention. In addition, the auction includes a normal auction in which a successful bid is made for an item for sale offered for sale and a reverse auction in which a successful bid is made for an item desired to be purchased for purchase. Now, a normal auction will be described as an example.
[0017]
FIG. 1 is an overall configuration diagram showing an embodiment of an auction system to which the present invention is applied. In the figure, an auction server 1 is an auction system that provides a wide range of auction services to users via a web server 2 and the Internet 20. The auction server 1 prepares an interface screen for providing an auction service at a site specified by a URL (Uniform Resource Locator) which is an address on the World Wide Web (WWW). This screen is usually described in HTML (Hyper Text Mark-up Language) format and can be viewed from each terminal connected to the Internet 20.
[0018]
A user 12 using this service accesses a site providing the auction service from a client 13 which is a user terminal connected to the Internet 20. The connection from the user terminal 13 to the Internet 20 is performed in a dial-up format via a corporate LAN or the like or via a telephone line. The user terminal 13 is installed with a connection program to the Internet 20 and a browser for browsing each site on the WWW.
[0019]
The interface screen provided by the auction server 1 is composed of a plurality of hierarchized pages like any other interface screen on the WWW, and anyone can access the main page of the auction, which is the top page. It is. After that, when using an auction service such as listing or bidding, it is necessary to register the user's name, address, e-mail address, etc., and become a member through a certain authentication procedure.
[0020]
As shown in FIG. 1, in addition to the web server 2, the auction server 1 includes an auction DB (database) 4 which is a database storing various data, program module groups 6 to 9 for executing various processes of the auction service, and It is constituted by a mail server 3 for contacting a user for an auction service. The auction database 4 stores various data necessary for the auction service, such as a user database having registered user information, an exhibition database having exhibit information, a bid database having bid information, and a successful bid database having bid information. .
[0021]
The program module group includes, for example, an enrollment module 8 that stores user registration information in a user database when a user enrolls, and sends a confirmation e-mail to a registered e-mail for an authentication procedure. When there is an exhibition request, the exhibition module 9 that registers the information of the exhibition item in the exhibition database, and when there is a bid request for the exhibition item, the bid information including the bid price is registered in the bid database. And a bidding module 7 for determining, for example, a user who bids at the highest bid price in a normal auction as a winning bidder, or determining a winning bidder and a winning bid amount for the number of items exhibited in a so-called Dutch auction. Etc. In addition, a page display module (not shown) that generates a display screen for the user reflecting information processed by each program module is also provided.
[0022]
Further, FIG. 1 shows a mail server 16 in which a user 12 registers a main e-mail address (referred to as a main registration address) and another sub-email address (referred to as a CC address) registered therein. Are connected to the Internet. In the example of FIG. 1, the user 12 includes a main client 13 that is set to receive an e-mail to the main registration address, and a CC mail client that is set to receive an e-mail to the CC address. 14 and can be used.
[0023]
The main client 13 is a personal computer installed at the home of the user 12, for example, and the CC mail client 14 is a personal computer installed at the workplace of the user 12, or a personal computer installed at the destination of the user 12, for example. Or a portable information terminal or a mobile phone carried by the user 12.
[0024]
When the CC mail client 14 is a portable information terminal or an i-mode compatible mobile phone, it is possible to receive a document file described in simple HTML and display the web page. When the clients 13 and 14 are ordinary personal computers, a document file described in ordinary HTML can be received and the web page can be displayed. That is, the document file formats that can be handled by the main client 13 and the sub client 14 are different.
[0025]
FIG. 2 is a diagram illustrating an example of a hierarchical screen of the auction site. FIG. 2 shows the top page 22 of the auction site. The top page 22 includes an area 24 for performing category search or keyword search for selecting an exhibition item, an enrollment button 26 linked to the enrollment registration form screens 32 and 34 used when the user is enrolled, and the user exhibits an exhibition. An exhibition button 28 linked to the exhibition registration form screen 36 to be used at the time, and a service counter button 30 linked to various member service screens 38.
[0026]
When the user wishes to join, the membership registration form screens 32 and 34 are displayed, and the name, address, telephone number, e-mail address, user ID, password, etc. are filled in and returned to the auction server 1. The enrollment procedure is performed by the enrollment module 8, and the specific procedure will be described later. What is characteristic here is that a column for entering the main address and the sub (for CC) address is provided in the e-mail address. The main address is an essential requirement for membership, and the sub address can be registered by user selection. Note that the membership registration form includes a personal use 32 and a corporate use 34, and a representative name and a person in charge are added to the corporate use form.
[0027]
When the user 12 makes an exhibition using this auction service, the user clicks the exhibition button 28 from the auction top page 22 to display the exhibition registration form 36 and inputs information on the exhibit (item). To do. The input information is registered in the exhibit database in the auction DB 4 by the exhibition module 9. Information on the registered exhibition items is appropriately searched by the page display module and displayed on the auction page as an exhibit list.
[0028]
FIG. 3 is a diagram illustrating an example of a bid screen. When the user 12 bids, the desired exhibit list is displayed from the search screen 24 of the top page 22. When a desired item is selected from the exhibit list, a bid screen 48 shown in FIG. 3 is displayed. The bidding screen 48 includes an item information area 50 including item information, a current highest bid price, a bid closing time, etc., a seller information area 52 including a seller ID information and a profile which is evaluation data in past transactions, And the successful bidder right ID information area 54.
[0029]
Further, the bid screen 48 has a bid area 56. A user who wishes to bid enters his / her ID and password in the bidding area 56, selects normal bidding or agent bidding (a function to automatically re-bidding when out-bitting), and enters the bidding price. The button 58 is clicked to send bid information to the auction server 1. Based on the input bid information, the bidding module 8 performs an update display of the bidding status including the update of the current highest bidding price, and contacts the bidder as necessary. The bid is completed when conditions such as a bid deadline such as a preset auction method are satisfied, and the successful bidder is determined by the general bidding module 7. Then, the fact is notified to the successful bidder and the exhibitor and reflected on the display screen. In the case of a reverse auction in which the exhibitor who has presented the lowest bid price makes a successful bid, the lowest bid price is displayed on the bid screen 48.
[0030]
Returning to FIG. 2, when the user wants to receive various services, the service counter button 30 on the top page is clicked to display the service counter screen 38, and a necessary service button is selected and clicked. Types of services include changes to registered contents and inquiries 40, status changes 42 for changing from individual members to corporate members, or vice versa, point purchases for inquiring prepaid purchases and current balance Inquiry 44, evaluation input / inquiry 46 for inputting and inquiring about evaluation of the user's past transactions.
[0031]
In the auction site, the exhibition fee and the contract fee when the auction is closed are paid in advance, and the deposit is the above point. In addition, since it is an auction in which a large number of unspecified individual users participate, when a transaction is established, the other party's response to the other party is evaluated and the evaluation is accumulated. The past evaluation data is displayed by the profile button in FIG. 3, and it is possible to determine whether or not to bid by referring to the seller's evaluation.
[0032]
4 and 5 are diagrams for explaining the membership procedure. The admission procedure flow is briefly shown in the lower right of FIG. The user 12 who wishes to join uses the browser of the client 13 to display the membership registration forms 32 and 34 from the top page 22 and enters the main e-mail address 60 along with the name and address. The user 12 can also register a CC address 62, which is a sub-email address, if desired. The user 12 fills in necessary items, and then transmits the completed membership registration form to the web server 2 of the auction server 1.
[0033]
The enrollment module 8 examines the items entered in the enrollment registration form, and if it can be authorized, returns an e-mail confirmation code from the web server 2 to the user client 13 for display. This completes the membership procedure on the web page.
[0034]
Thereafter, the membership module 8 sends the membership confirmation mail to the mail server 16 of the main electronic mail address (main registration address) where the membership mail is registered by the mail server 3 to confirm the identity. Encourage replies. Then, the user 12 receives an enrollment confirmation mail by the main client 13 and returns an e-mail confirmation code indicated in the enrollment procedure on the web page. The enrollment module 8 confirms that the mail confirmation code matches and completes the identity verification. Thus, the main e-mail address is used for identity verification in cyberspace.
[0035]
Finally, as shown in FIG. 5, the membership module 8 registers user information in the user database in the auction database 4. In addition to the main e-mail address, the user data includes a sub CC mail address for the desired user.
[0036]
After completing the registration, the user will receive auction services such as bidding and listing. The auction service includes listing items, bidding on the listed items, and receiving other auction notification emails.
[0037]
FIG. 6 is a diagram showing an example of a notice mail screen which is one of auction services. Regular auction events and exhibition information are sent to users who have registered as members via a notification email. In the example of FIG. 6, notifications about speed auction items and special auction items are included. Such a notification mail with a low urgency level that does not require the user to respond promptly is sent from the mail server 3 to the main e-mail address (main registration address) registered by the user.
[0038]
FIG. 7 is a diagram illustrating an example of an auction successful bid failure mail screen. Such a successful bid failure mail is sent to users who have not been able to make a successful bid among the users who participated in the bidding. In the example of FIG. 7, the auction lot number and item name, the final winning bid price, and the winning bidder ID are included. Since this successful bid failure mail is also a mail that does not require the user to respond promptly, it is sent from the mail server 3 to the main e-mail address (main registration address) registered by the user. In addition to this, an unsuccessful successful bid mail notifying that the auction itself has flowed due to reasons such as the successful bid price not reaching the minimum price is similarly sent only to the main e-mail address.
[0039]
FIG. 8 is a screen example of the highest bid price update mail. In a normal auction, among users who participated in bidding, the user who presented the highest bid price is displayed as the successful bidder on the successful bid screen in FIG. 3 (54 in FIG. 3). However, if another user presents a higher bid price, the right to win is lost. In that case, an out-bited user may desire immediate re-bidding for reasons such as when there is no time until the successful bid deadline. Therefore, when the highest bid price is updated, the bid module 6 transmits a highest bid price update mail as shown in FIG.
[0040]
Since this highest bid price update mail is a highly urgent e-mail requesting a prompt response from the user, the bidding module 6 sends this mail to both the main registration address of the user 12 and the CC mail address. . Therefore, even if the user who has lost the successful bid right cannot receive the mail of the main registration address from the main client 13 at home, he receives the mail transmitted from the sub CC mail client 14 to the CC mail address. be able to.
[0041]
FIG. 10 is a diagram for explaining the transmission of the highest bid price update mail. The bid module 6 transmits the highest bid price update mail shown in FIG. 8 to both the main registration address and the CC address to the user who has lost the bid right. Then, the user can receive the mail by any one of the clients 13 and 14. Therefore, if desired, the user 12 can access the bidding screen and place a bid again, so that the opportunity for bidding is not missed.
[0042]
Returning to FIG. 8, as an auction service, the highest bid price update mail screen 71 can include a hyperlink 70 to a bid screen when re-bidding. This hyperlink 70 is “HYPERLINK“ http://www.bidders.co.jp/bid/YYYY ”http://www.bidders.co.jp/bid/YYYY”, the lot that has lost the right to bid. Contains the URL to the bid screen for the number YYYY. Therefore, the user who has lost the right to bid can click the link 70 to display the bid screen 48 shown in FIG.
[0043]
As a more preferred embodiment, the browser of the main client 13 to which the main registration address is set can display a normal HTML document, and the browser of the CC mail client 14 can display a simple HTML document. There is a case. This is a case where the main client 13 is a personal computer and the CC mail client 14 is an i-mode compatible mobile phone, a palmtop type portable information terminal, or the like. In that case, it is desirable to link to a bid screen described in a format that can be supported by each browser.
[0044]
In that case, as shown in FIG. 10, the bidding module 6 creates the highest bid price update mail document 71A for the main registered address and the mail document 71B for the CC address, and the mail server 3 is sent to each address. To send through. The highest bid price update mail document 71A for the main registration address includes a hyperlink 70 to the bid screen described in the normal HTML document, and the mail document 71B for the CC address is described in the simple HTML document. A hyperlink 70 to the bid screen is included. Accordingly, the user can perform a re-bidding by displaying the instant bidding screen in the environment where each e-mail is received.
[0045]
FIG. 9 is a diagram showing an example of a successful bid mail screen. When a predetermined successful bid condition such as a successful bid expiration date is established, the successful bid module 7 determines a successful bidder. Then, the successful bid module 7 transmits a successful bid mail to the successful bidder and the exhibitor, and transmits a successful bid failure mail (FIG. 7) to the user who has made a bid but failed to make a successful bid. In that case, it is necessary to conduct a post-successful transaction including settlement such as remittance and shipment of exhibition items between the successful bidder and the exhibitor who have made a successful bid. For example, a transaction that the successful bidder selects and notifies from the desired transaction method presented by the seller (cash on delivery service, shipping after bank transfer, shipping after arrival by registered mail, etc.), or notification of completion of shipping or transfer completion Is done.
[0046]
Since the transaction after the successful bid is performed between the exhibitor and the successful bidder, there is a possibility that the transaction is not performed satisfactorily for an unfamiliar user. Therefore, as one of the auction services, there is a navigation function for transactions after a successful bid. For example, a mail in which the successful bidder notifies the seller of selection of a transaction form, a shipping notification mail by the seller in the case of cash on delivery, a mail for notifying items received by the successful bidder, etc. are standardized, and the auction server 1 is a web server. The creation of such a notification mail is supported via 2, and the created notification mail is transmitted from the mail server 3. Therefore, by using this transaction navigation function, the exhibitor or the successful bidder only has to input necessary information on the web page and send it to the auction server 1 and supports successful transactions after the successful bid. Is done. The transaction navigation function is described in detail in Japanese Patent Application No. xxxxxxx filed separately by the present applicant.
[0047]
Accordingly, the successful bid completion mail screen 73 in FIG. 9 includes a hyperlink 72 when using transaction navigation. The successful bidder who has received the successful bid mail can click the hyperlink 72 to display the web page of the input form for creating the transaction form selection notification mail by the browser.
[0048]
FIG. 11 is a diagram for explaining the transmission of the successful bid mail. The successful bid module 7 determines the winning bidder and sends a successful bid mail to the winning bidder via the mail server 3. Also in this case, a successful bid mail is transmitted to both the main registered address of the successful bidder and the CC address. Therefore, the user 12 can receive the successful bid mail by any of the available clients 13 and 14. Therefore, it becomes possible to quickly enter into a transaction after a successful bid.
[0049]
Similarly to the highest bid price update mail screen, the successful bid mail has a hyperlink 72 including a URL address. Accordingly, when the HTML documents that can be received by the main client 13 and the CC mail client 14 are different, URLs to HTML documents that can also correspond to the hyperlink 72 are included in the respective successful bid completion mails 73A and 73B. Thereby, the user 12 can start the transaction after the successful bid from the available clients 13 and 14 immediately using the transaction navigation function.
[0050]
In the present embodiment, the highest bid price update mail and the successful bid completion mail are transmitted to both the main e-mail address and the sub e-mail address. However, the present invention is not limited to this. For example, in the case of a reverse auction service in which an exhibitor presenting the lowest price can make a successful bid, it is desirable that the lowest bid price update mail is also transmitted to the main and sub-email addresses. The maximum bid price update mail in the normal auction and the minimum bid price update mail in the reverse auction can be referred to as a right acquisition bid price update mail, for example. Other than that, notification mail having urgency can be transmitted to the main and sub email addresses, and notification mail having no urgency can be transmitted only to the main email address.
[0051]
As described above, the protection scope of the present invention is not limited to the above-described embodiment, but extends to the invention described in the claims and equivalents thereof.
[0052]
【Effect of the invention】
As described above, according to the present invention, in an auction service using a network, an urgent notification mail is transmitted to the user's main and sub email addresses, and other notification mails are transmitted only to the main email address. Therefore, it is possible to provide a more convenient service to the user while suppressing the traffic volume in the auction server system.
