Description

Method for distribution of goods belonging to the state treasury}

The present invention relates to a technology for distributing goods belonging to the national treasury, and more particularly, to a method and apparatus for distributing goods belonging to the national treasury, which enables various goods reverted to the national treasury to be distributed on the market through the Korea Customs Service. .

In general, commercial transactions conducted off-line can be classified into electronic commerce between businesses, electronic commerce between businesses and consumers, and commerce between businesses and governments.

For example, there are various shopping malls to realize commercial transactions between companies and consumers, and bidding for government procured goods from the Public Procurement Service and bidding for various goods reverted to the national treasury through the Korea Customs Service are one of the commercial transactions between corporations and the government. there is

Transactions between the government and companies refer to the public announcement of bids for goods, construction, or services by the ordering organization, such as the Korea Customs Service, and receiving and reviewing applications from applicants to bid to determine the appropriate successful bidder.

However, in the case of offline commercial transactions, it takes a lot of time from participation in bidding to winning a bid, excessive documents to be submitted for participation in bidding, and duplicate documents must be submitted each time bidding is participated. This heavy workload requires a large number of people and time for both the party that announces the bid (bidder) and the party that participates in the bidding (bidder) to perform tasks such as bidding.

In recent years, with the widespread use of the Internet, commerce that was previously conducted offline is being conducted online. In this way, when offline commerce is conducted online, information spreads quickly and costs and time are saved when participating in bidding. Accordingly, the problem of the offline bidding method can be solved.

However, compared to offline bidding, the conventional online bidding has many advantages in that documents to be submitted are simplified and the time from participating in the bidding to winning the bid is shortened. There was a growing problem.

In other words, in the case of bidding conducted online, such as the Internet, documents to be submitted are simplified and the time from participation in the bidding to successful bidding is shortened compared to the above-described offline bidding. In addition, in the case of using the reverse auction method, by setting the successful bid price to the lowest price, it is possible to receive a supply of goods or a service of construction or service at a low cost. That is, the bidding cost can be reduced compared to offline.

However, even if the documents submitted online are simplified compared to offline, there are many cases in which there are many required documents for some bidding, and errors occur in the process of preparing and reviewing all of these documents, If an error occurs when a file is transmitted online, such as the Internet, various problems may occur, such as canceling the bidding itself or changing the bidding result. In particular, after the bidding is decided, post-work according to the bidding result may not be carried out due to the above problems, etc., and the friction between each company due to the above problems deteriorates the reliability of the corresponding company.

Publication No. 10-2002-0004901 (2002.01.16.)

The present invention was created to solve the above-mentioned conventional problems, and its purpose is to distribute various goods belonging to the national treasury through online bidding with security secured through the Korea Customs Service. It is to provide a method and apparatus for

As shown in the figure, the apparatus 20 is connected to the bidding server 2 of FIG. 1 It may include a product receiving unit 21, a bid notification unit 22, a bid unit 23, a ticketing unit 24, a synchronization unit 25, and an authentication unit 26.

The goods reception unit 21 is for receiving bid (expected) goods provided from the Korea Customs Service, and can receive and accept EDI documents related to the bid goods generated by the Korea Customs Service server 6 through the EDI VAN company system 4.

The bid announcement unit 22 is for posting a bidding announcement related to the bidding item on the homepage of the bidding server 2, and registers the corresponding bid item based on the EDI document related to the bid item received through the item reception unit 21 and bids. Bidding notices may be posted on the website.

The bidding unit 23 allows Internet members with bidding member qualifications to view the bidding announcement posted on the bidding homepage through the bidding announcement unit 22 of the bidding server 2 and bid for the corresponding bid, and also to give the bidder a deposit. For example, a bidding member accesses the bidding server 2 through the client terminal 3 to view the bidding details of the bidding announcement posted on the bidding homepage, and bids including the bidding amount (Bidding) If you submit a bid by creating a document, you can receive it and create a virtual bank account for the bidder to pay a certain percentage (eg 10%) of the bid amount as a bid deposit. In addition, the bank VAN company system (5) Through this, it is possible to check whether the bid deposit from the bidder has been paid.

When the bidding time through the bidding unit 23, that is, the predetermined bidding time, is closed, the ticketing unit 24 opens the bid, notifies the bidder of the result of the bid (eg successful bid or unsuccessful bid), and allows the successful bidder to pay the balance. To do this, it is possible to notify the bidding member of the details of the successful bid or unsuccessful bid as a result of the opening bid, and also allow the successful bidder to pay the balance of the bid (ie, the amount remaining after subtracting the bid deposit previously paid from the bid amount), In addition, it is possible to check whether or not the balance of the bid from the successful bidder has been paid through the bank VAN company system 5.

Details of successful bids or failed bids may be notified to the relevant bidding member via e-mail or posted on the bidding member's My Page prepared in the bidding server 2 so that the relevant bidding member can read them.

When a certificate request message including Internet bidding member information and a bidding security key is received from the client terminal 3, the certificate requesting unit 261 may recognize that a certificate for bidding has been requested from a corresponding Internet bidding member.

The first certificate generating unit 263 is for generating a first certificate when a certificate is requested through the certificate requesting unit 261, and the configuration of the first certificate is, for example, as shown in (a) of FIG. May include Version, Serial Number, Signature Algorithm ID, Issuer (CA), Validity Period, Subject, Subject Public Key Info, Algorithm ID, Public Key Value, Issuer Unique ID, Subject Unique ID, Extension, and CA Digital Signature .

Among the components of the first certificate of FIG. 6 (a), information on the components of Version, Signature Algorithm ID, Issuer (CA), Validity Period, Subject Public Key Info, Algorithm ID, Issuer Unique ID, Subject Unique ID, and Extension is the same as other certificates of the same type, and the remaining Serial Number, Subject, Public Key Value, and CA Digital Signature component information are unique values that are different for each certificate issued in units of secure IoT smart sensor devices (2) have

The second certificate generator 265 removes components common to other certificates of the same type among the components of the first certificate generated through the first certificate generator 263 and leaves only the minimum required components required for authentication. For generating a dieted second certificate, for example, Version, Signature Algorithm ID, Issuer (CA), Validity Period, Subject which are components common to other certificates of the same kind in the first certificate of FIG. Information on Public Key Info, Algorithm ID, Issuer Unique ID, Subject Unique ID, and Extension is removed, and the remaining (required) components are a diagram consisting only of information on Serial Number, Subject, Public Key Value, and CA Digital Signature. A second certificate can be generated as shown in (b) of 6.

The certificate issuing unit 267 is for issuing the second certificate generated through the second certificate generating unit 265 to the corresponding Internet bidding member through the client terminal 3 .

According to an embodiment of the present invention, the size (data size) of the diet certificate (ie, the second certificate) from which common components are removed is significantly reduced compared to the original certificate (ie, the first certificate), so that it can be loaded even in low-spec memory. have.

4 is a flow chart of a method for distributing national treasury goods according to an exemplary embodiment of the present invention, and since it is applied to the device of FIGS. 1-3, the operation of the device will be described in parallel.

First, the entire process of FIG. 4 will be described in general.

Steps S401 to S407 are for the bidding server 2 to select and register products to be raised by electronic bidding based on the EDI documents related to the bidding products provided from the Korea Customs Service server 6, describe the bidding details, and post (announce) on the bidding website. represents the process.

In step S409, an Internet member with bidding membership accesses the bidding server 2 through the client terminal 3 and participates in electronic bidding based on the bidding information posted (announced) on the bidding website (a deposit is required for participation). indicates the process for

Step S411 represents a process in which the manager proceeds to open a bid in the bidding server 2 after the bidding is completed.

Step S413 represents a process of notifying successful bids and unsuccessful bids (returning the deposit in the case of unsuccessful bids) to bidding members who have participated in the bid after the bid opening is completed.

Step S415 represents a process of confirming the successful bid balance transfer through the program of the bank VAN company system 5 associated with the bank.

Step S417 represents a process of generating an EDI (Electronic Data Interchange) document related to a bidding result (a successful bid or a failed bid) in the bidding server 2 (creating data with a 10% reduction in the case of a failed bid).

Steps S419 to S421 show a process of transmitting the EDI document generated in step S217 from the bidding server 2 to the Korea Customs Service server 6 through the EDI VAN company system 6.

Steps S423 to S425 show a process of transmitting an acknowledgment (ACK) message for the EDI document received in step S421 from the Korea Customs Service server 6 to the bidding server 2 through the EDI VAN company system 6.

Step S427 shows a process for reflecting the EDI document ACKed in the bidding server 2 to the bidding information and the database.

Next, the entire process of FIG. 4 will be described in detail.

First, the Korea Customs Service server 6 generates an EDI document related to a bid item (S401) and transmits it to the bidding server 2 through the EDI VAN company system 5 (S403) (S405).

When the bidding server 2 receives the EDI document related to the bidding item provided from the Korea Customs Service server 6 through step S405, registers the bidding item based on the received EDI document and proceeds with the bidding. For example, in step S405 It is possible to start bidding by registering the relevant bidding item based on the EDI document related to the bidding item received from and posting a bidding notice through the bidding homepage (S407).

Then, the bidding member accesses the bidding server 2 through the client terminal 3, sees the bidding details of the bidding announcement posted on the bidding homepage, creates a bidding (bidding) document including the bidding amount, and makes a bid. The server (2) receives this and creates a virtual bank account for the bidder to pay a certain percentage (eg 10%) of the bid amount as a bid deposit, and deposits the bid deposit from the bidder through the bank VAN system (5). Check whether or not to pay (S409).

In general, members who sign up for bidding first check the item offline before participating in the bidding, then look at the bidding details posted on the bidding website, enter the bidding amount, and 10% of the bidding (bidding) amount stated. is paid as a bid deposit, and the bid deposit is paid through the virtual account generated at this time.

Subsequently, the bidding server 2 proceeds with the bid opening by the manager after a certain time elapses after the closing of the bidding participation of the bidding members (10:00 am to 2:00 pm) (S411), and when the opening is completed, the winning bid details or The details of the failed bid shall be notified to the relevant bidding member, but at this time, the successful bidder shall be notified of the remaining balance of the bid (i.e., the amount remaining after subtracting the bid deposit previously paid from the bidding amount) at this time, together with the virtual account for balance payment and the closing date of the remaining balance to the successful bidder. After notifying (S413), it is confirmed whether or not the balance of the bid from the successful bidder is paid through the bank VAN company system 5 (S415).

Since e-bidding is conducted as a large-scale project and must be conducted organically with banks, the bank VAN company system (5) is used in the middle.

In step S413, notification is made by e-mail as an example, or by posting on the bidding member's My Page provided in the bidding server (2) so that the relevant bidding member can view it, or performing both of the above methods together. can do.

In step S415, the balance transfer can be confirmed by the Van company program uploaded to the bidding server 2 in the bank company system 5.

Subsequently, the bidding server 2 generates a successful bid detail document as an EDI document when the bidding result is a successful bid, and generates a failed bid detail document as an EDI document when the bid is unsuccessful (S417).

In step S417, when the bid fails, that is, when there is no successful bidder (for example, when no bidding members participate) in the corresponding bid, a related failed bid heat-resistant document is generated as an EDI document. For example, the bidding server 2 bids Documents (document number 2021-45, current N round, next N+1 round, product information, current N round bidding amount of 1,000,000 won, next N+1 round of bidding amount, including information such as 900,000 won, etc. create with

When the bid is successful in step S417, sales details including information related to the successful bid are generated as EDI documents, and a certificate for export is output.

Subsequently, the bidding server 2 transmits the EDI document generated through step S417 to the Korea Customs Service server 6 through the EDI VAN company system 4 (S419) (S421).

In steps S419 to S421, the bidding server 2 and the Korea Customs Service server 6 use the EDI VAN company system 4, which is a document transfer relay system, in the middle to prevent document transfer accidents and ensure security, and the EDI VAN The EDI document is delivered to the program provided by the company system 4. The EDI VAN company system 4 transfers the document to the customs office server 6 of the receiving side if no error has occurred in the EDI document of the originating side.

When the EDI document related to a failed bid or a successful bid is received through steps S419 to S421, the Korea Customs Service server 6 organizes a related database and transmits an acknowledgment (ACK) message to the bidding server 2 through the EDI VAN company system 4. (S423~S425).

Finally, in the case of a failed bid, the bidding server 2 subtracts a certain percentage (eg 10%) from the lowest bid price (eg 1,000,000 won) of the current bid announcement posted in the N (N is a natural number) round (eg, 1,000,000 won). 900,000 won) is reflected as the minimum expected bidding amount for the next N+1 round, and a bid is announced, and in the case of a successful bid, for example, if the balance is completed on 2021-01-10, 2021-01-11 sales details After EDI is delivered to Van and notified to the Korea Customs Service, the EDI delivered from the Korea Customs Service is reflected in the related database and recorded as sales details (S427).

5 is a flowchart illustrating a method for generating a diet certificate (ie, a second certificate) according to an exemplary embodiment of the present invention.

The authentication unit 26 of the apparatus 20 for distributing goods belonging to the national treasury of the bidding server 2 may generate and issue a bidding certificate for each bidding member according to the request of each Internet bidding member, and the process is as follows. same.

First, the client terminal 3 of the bidding member generates member information and a security key (S501), and transmits a certificate request message including the generated member information and security key to the bidding server 2 to request a certificate. (S503).

The bidding server 2 extracts a security key from the certificate request message received through step S503 (S505), and generates an original first certificate as shown in FIG. 6 (a) based on the extracted security key (S507). , Version, Signature Algorithm ID, Issuer (CA), Validity Period, Subject Public Key Info, Algorithm ID, Issuer, which are components common to other certificates of the same kind, among the components of the generated first certificate of FIG. 6 (a) A diet consisting only of information on Serial Number, Subject, Public Key Value, and CA Digital Signature as the remaining (essential) components as shown in (b) of FIG. 6 by removing information on Unique ID, Subject Unique ID, and Extension. A second certificate is extracted and generated (S509).

Next, the bidding server 2 encodes the second certificate generated through step S509 (S511) and provides (issues) it to the client terminal 3 (S513), and the client terminal 3 receives the second certificate through step S513. 2 The certificate is stored, and upon renewal, it is renewed and stored instead of the pre-stored second certificate so that authentication with the bidding server 2 is performed at the time of bidding (bidding) (for example, when participating in the electronic bidding in step S409 of FIG. 4) (S515 ).
