Description

Electronic bidding method using the internet {The method of electronic bidding system through the internet}

The present invention registers and announces the contents of the contract for the construction and service of the project (hereinafter referred to as "service business"), sets the desired price and successful bid range for the service, and a number of bidders It is about how to select winners by selecting the best bid among them.

Determining who provides the product, service, etc. (collectively referred to as the "supplier") and who purchases it (collectively referred to as the "buyer") includes auctions, reverse auctions and Bidding and the like. Auction is a method in which a plurality of buyers raise a price for a product or the like that a supplier initiates to determine a buyer who presents the purchase price among the buyers. Reverse auctioning, on the contrary, is a method in which a supplier proposes a supplier price by lowering a price that can be supplied by a plurality of suppliers for the same product, etc., and determines a supplier who has provided the lowest supply price among them. Bidding is a method in which a plurality of buyers or suppliers submits a desired price in a secret manner, and discloses it at a time and selects a buyer or supplier who has offered the lowest or best price as a successful bidder.

Auctions are frequently used to buy cheap products, and reverse auctions are used to manufacture cheap products. Bidding is used as a way of solving defects or insolvency caused by the problem of low cost.

Currently, auctions and reverse auctions are widely used in the cyber space such as the Internet, and despite its problems, it has overcome the limitations of the rapid dissemination of the Internet and restriction of places. It is growing fast because of its merits.

However, in the case of a field requiring a bidding method to select an optimal price rather than the lowest price, for example, a contract for a machine or a building, the auction or reverse auction in the virtual space currently used is not suitable. .

This is because the successful bidder who suggested the lowest price is more likely to perform defect work or poor construction to compensate for the damages caused by the lowest price. There may be a method of determining the price in advance and recruiting those who can respond, and selecting it through a lottery, but there is a problem in the fairness of the selection method. As an example of bidding in real space, the tendency of bidders to use the wrong method to obtain information on the winning price until the bid deadline due to the nature of the bidding occurs. As a result, bad companies are winning bids, causing social problems. In addition, even after a successful bidder is decided, employers, successful bidders, and business guarantee companies continue to pay additional costs for bidding due to the constant issue of the successful bidding process.

Accordingly, an object of the present invention is to solve a problem of a bidding method in a real space in a virtual space and to solve a problem of auction and reverse auction in a virtual space.

More specifically, the present invention by participating in the bidding through the Internet, bidders can freely participate in the bidding wherever the Internet is connected, and if you want, you can book the price opening after closing the bid conveniently Do it. In addition, by participating in the bid at a remote location it can prevent unfair collusion between bidding companies.

In addition, the present invention can keep the decision-making process of the successful bidder by not exposing any price information related to the successful bid of the service business to anyone, such as bidders, business owners, business guarantee companies, etc. through encryption. In addition, all signatures can be digitally signed in order to prevent successful rejection of bid results and bidding.

Although the configuration and operation of the electronic bidding method and apparatus according to the present invention will be described in more detail with reference to the accompanying drawings, the scope of the present invention is not limited by the above exemplary description.

1 is a network diagram of an electronic bidding apparatus according to an embodiment of the present invention. That is, the authentication and digital signature devices and services installed on the computer of the business owner (11), the guarantee company (12) who wants to participate in the service business, and the bidder (13) who wants to participate in the service business. It consists of a bidding server 10 for processing the bidding process and the authentication process of each participant, and the Internet 14 for transmitting and receiving data between these devices.

2 is a schematic diagram of an electronic bidding device according to an embodiment of the present invention, showing the schematic configuration and operation of the electronic bidding device. The bidding server of the electronic bidding device is a user registration unit 20 that allows the business owners, sponsors and bidders of the service business to use the bidding server, a database for managing the information of the registered users and the bidding business (25) ), The database interlocking unit 24 for transmitting the contents of the database through the Internet, the authentication unit 21 for authenticating users so that they cannot steal others' names, and each user can register and modify his own participation price. The bid receiving unit 22 to restrict the information so that no more information can be modified after the bidding is closed, input the unencrypted participation price compared to the previous encrypted information to maintain the consistency of the price information, the price information It is composed of a bid verification and processing unit 23 to determine whether a successful bid or bid based on.

The operation of the electronic bidding device according to an embodiment including the guarantee company is as follows. First, the business owner, the guarantee company, and the bidding company wishing to participate in the bidding project apply for registration through the register 20. The contents of the application are all recorded in the database 25.

When the business owner obtains the certification as a business owner through the authentication unit 21, the desired successful bid price and the successful bid range are encrypted, the digital contents of the encrypted contents are transmitted through the bid reception unit 22, and the database interworking unit 24 is The encrypted and digitally signed contents are recorded in the database 25.

After acquiring the user certification as the assurer through the certification unit 21, the assurer encrypts the minimum guarantee price of the service business, digitally signs the encrypted contents, and transmits it through the bid receiving unit 22. The database interworking unit 24 finally records the encrypted and digitally signed contents in the database 25.

In the same manner as described above, the bidder acquires the certification as a bidding participant in the authentication unit 21, and then encrypts the bid price and digitally signs the encrypted contents, thereby bidding unit 22 and database interworking unit. The data is finally recorded in the database 25 through the code 24.

When the bid is closed, the business owners, insurers and bidders are sent to the bid verification and processing unit 24 without encrypting the data presented before the bid deadline. The verification and processing unit 24 of the electronic bidding device encrypts the transmitted content without encryption and compares it with the contents already encrypted and stored in the database. At this time, if the same encryption contents are confirmed, the bidding and bidding is determined based on the desired price and bidding range suggested by the employer and price information presented by the guarantee company. The company that bids the lowest price among those bidding within the desired price and bidding range of the key is selected as the bidding company. If the bid price of the successful bidder is higher than the guaranteed price of the guarantee company, the successful bidder shall enter into a contract with the assurer for the performance guarantee and the defect repair guarantee for the relevant service business, and then enter into a contract for the construction work and carry out the service work. . If the bid price of the successful bidder is lower than the guaranteed price of the guarantee company, the successful bidder only enters into the construction contract with the employer, and the guarantee company is not responsible for the construction and repair of the defect.

Referring to Figure 3 when explaining the bidding method of the service employer. First, a business owner registers a business owner with a bid server and receives a business owner registration number. After the bidding announcement for the service project, etc., the certification number is issued through the certification process of the bidding server. The employer encrypts the desired price and the bidding range for the bidding construction with the registration number and the certification number according to the prescribed method, and applies the bid through the bid reception unit of the bid server by digitally signing the encrypted contents. When the bid is closed, the employer fixes all bid information, and transmits to the verification and processing unit of the bid server without encrypting the registration number, certification number and the desired price and successful bid range provided before the deadline. At this time, the bid server encrypts the unencrypted information by a predetermined method and verifies whether the contents are identical to the encryption contents provided by the employer before the deadline. After the verification, the bidder decides the bidding or bidding based on the bidding price of the guarantee company and the bidding company. If the successful bidder is decided, the winning bidder is announced and the contract construction contract with the successful bidder. If the bidding bid is not made because the successful bidder is not decided, the employer pushes new bids again from the announcement of the service project.

Referring to Figure 4 describes the bidding method of the guarantee company as follows. The guarantee company registers the guarantee company with the bidding server and receives the guarantee company registration number. When the verification number is issued through the verification process of the bidding server, the guarantee company encrypts the guarantee price along with the registration number and the verification number according to a predetermined method, and electronically signs the encrypted contents to apply for bidding through the bid reception unit of the bid server. Do it. When the bid is closed, the guarantee company does not encrypt the registration number, certification number, and guarantee price provided before the deadline, and sends it to the verification server of the bid server. At this time, the bid server encrypts the unencrypted information by a predetermined method and verifies whether the same as the encryption contents provided by the guarantee company before the deadline. After the verification, the winner is determined based on the owner's desired price and the bidding price of the bidder. If the bid price of the successful bidder is higher than the guaranteed price, the assurer enters into a guarantee contract with the employer and the successful bidder for the performance of the service business and the repair of defects. If the bid price of the successful bidder is lower than the guaranteed price, the guarantee company does not provide any guarantee for the service, and the employer and the successful bidder enter into a contract for the implementation of the service and the repair of defects. If no successful bidder is determined, the assurer can start a new service bidding process from the assurer's certification stage.

Referring to Figure 5, the bidding method of the bidding company will be described. The bidder registers with the bidder, receives the registration number, and receives the verification number through the authentication step. The bid price together with the registration number and certification number is encrypted by a predetermined method, and the bidding application is made through the reception unit of the bid server by digitally signing the encrypted contents. When the bid is closed, the bidder does not encrypt the registration number, certification number, and bid price provided before the deadline, and transmits them to the verification and processing unit of the bid server. At this time, the bid server encrypts the unencrypted information by a predetermined method and verifies whether the bidding information is identical to the encryption contents provided by the bidding company before the deadline. After the verification, the winner is determined based on the desired price of the employer. If the winning bid price is higher than the guarantee price of the guarantee company, the winning bidder shall enter into a contract with the employer, contracts for construction and defect repair with the guarantee company, and proceed with the relevant project. If the bidder is not determined because the successful bidder is not decided, the bidder may push new bidding from the certification stage.

According to the present invention, the electronic bidding system through the Internet can participate in a bid at a remote location, so that bidders can conveniently respond to the bidding, and broaden the range of people who can respond to the bidding so that the business owner can do a better condition service business. It can provide you with opportunities. Content that must be kept confidential in any bidding process is not exposed to interested parties through encryption, so that the bidding process can proceed fairly and transparently. Participating in bidding at a remote location prevents unfair collusion, which may be caused by the bidding companies. By conducting an electronic signature on the contents of the bid until the bidding proceeds to the selection of the successful bidder, it is impossible to deny the result of the successful bidding, thereby preventing the employer from inadvertent losses.
