Description

Trade Transaction Verification Platform Providing Method}

The present invention relates to a method of providing a trade transaction authentication platform, and more specifically, to a method of providing a trade transaction authentication platform that can improve the security and safety of trade transactions by applying the blockchain method.

Trade transactions involve various procedures involved in the international movement of goods or services.

For example, the trade transaction process goes through a series of processes such as concluding an export contract, export declaration, export notification, preparation and transportation of goods, import declaration, payment of tariffs and value-added tax, and customs clearance.

And today, most of the documents required for trade finance are sent via email or fax.

However, because this method has a high possibility of hacking and document forgery/falsification, it is abused during the export/import transaction process and becomes the cause of illegal foreign exchange transactions.

Cases of illegal foreign exchange transactions known to date include ‘evading property under the pretense of paying processing fees to an overseas local corporation,’ ‘escaping property by manipulating import prices at high prices under the guise of intermediary trade,’ and ‘government-run banks abusing import letters of credit.’ There are ‘fund embezzlement and money laundering’, ‘smuggling export and money laundering for the purpose of concealing comprehensive income tax sources’, and ‘unjust misappropriation of health insurance benefits through high import price manipulation’.

Additionally, according to statistics, from 2016 to 2020, the number of cases of damage from foreign exchange fraud transactions of trading companies identified in the domestic banking sector is 2,582, and the resulting loss is known to be worth 139.7 billion won (source: Financial Supervisory Service).

Just looking at the scale and number of damages described above, it is clear that current trade transactions cannot guarantee transparency or trust between business partners.

Therefore, there is an urgent need to develop a new platform that is more transparent and can increase credit between business partners.

In addition, the program for providing a trade transaction certification platform can be output through a video output device such as a display module, and a graphical user interface visualized on the platform provision server, user terminals owned by the parties to the trade transaction, and shipowner terminals owned by the shipowner of the trade ship. Visible information can be provided through .

In particular, the program for providing the trade transaction authentication platform can be installed on the platform providing server, user terminal, ship owner terminal, etc. using a removable disk or communication network, and the method for providing the trade transaction authentication platform is the platform providing server, user terminal, and ship owner terminal. It can be operated by various functional means.

In other words, in the present invention, information processing by software is concretely realized through hardware.

Hereinafter, a method for providing a trade transaction authentication platform according to an embodiment of the present invention will be described with reference to the attached drawings.

Figure 1 is a diagram showing the entire process of a method for providing a trade transaction authentication platform according to an embodiment of the present invention.

And Figure 2 is a diagram conceptually showing each configuration of a system for performing a method of providing a trade transaction authentication platform according to an embodiment of the present invention. In the following description, the codes assigned to each component are based on this drawing. do.

As shown in Figure 1, the method of providing a trade transaction authentication platform according to an embodiment of the present invention includes steps (a) to (h).

Step (a) is a process in which the user management unit 110 of the platform providing server 100 performs login authentication for a plurality of user terminals 10 owned by parties to an arbitrary trade transaction.

At this time, trade transaction authentication software provided by the platform providing server 100 may be installed on the user terminal 10, and parties to the trade transaction may be sellers, intermediaries, buyers, etc.

And in this step, the login authentication process for the user terminal 10 owned by each party can be applied in various ways.

In this embodiment, the user's account information can be protected by generating a random number for the password through a hash function and performing authentication.

Figure 3 is a diagram showing the detailed process of step (a) in the method of providing a trade transaction authentication platform according to an embodiment of the present invention.

As shown in FIG. 3, in this embodiment, step (a) may include steps (a-1) to (a-4) in detail.

Step (a-1) is a process in which the user management unit 110 receives a private key previously issued to the user terminal 10.

That is, for the login authentication process, private keys may be issued in advance to a plurality of user terminals 10 owned by parties to a trade transaction.

Such a private key may be stored on the user terminal 10 or in a separate storage medium, or may be stored in a data storage service provided by the database 105 of the platform providing server 100, such as the cloud. It can also be saved through .

Step (a-2) is a process in which the user management unit 110 calls the hash function assigned to the corresponding private key.

The hash function is a one-way function that maps arbitrary data of arbitrary length to data of fixed length. In this embodiment, the hash function applies a method of converting the password assigned to the private key into a random number value. .

Step (a-3) is a process in which the user management unit 110 generates a random number value by inputting the password corresponding to the corresponding private key into a hash function.

In this process, the user management unit 110 loads the password corresponding to the corresponding private key from the password data pool encrypted and stored in the database 105 of the platform providing server 100.

Then, the loaded password is entered into the hash function and a random number value is generated.

Step (a-4) is a process in which the user management unit 110 performs connection authentication processing for the user terminal 10.

That is, in this process, the random number generated in step (a-3) described above is entered as the login password for the user's private key, and connection authentication processing to the platform providing server 100 is performed.

As such, the present invention performs login authentication through a private key, enabling immediate login without the step of entering a separate ID and password, and prevents anyone from knowing the password assigned to the private key to secure the user's account. Information can be effectively protected.

Next, step (b) is a process in which the data processing unit 120 of the platform providing server 100 establishes a blockchain environment for transaction data holding related information about the trade transaction.

Here, relevant information about the trade transaction included in the transaction data may be, for example, transaction items, sources of transaction items, etc.

The data processing unit 120 builds a blockchain environment through such transaction data, so that a large number of information is bundled to form one data block, and the previous block and the subsequent block can be chained using the hash value.

In other words, the present invention allows the transaction parties, including the platform providing server 100, to jointly record and manage all or part of the trade transaction-related information included in the transaction data through a 'P2P (Peer To Peer) network', thereby reliability can be greatly improved.

Step (c) is a process in which the data processing unit 120 generates a transaction certificate corresponding to transaction data.

In this process, the transaction certificate can assign a preset identification code to various information included in the transaction data. For example, the identification code may be a QR code, but is not limited thereto.

In such identification codes, relevant information about trade transactions, such as transaction items and sources of transaction goods, are recorded, and a hash identification code can be recorded in the blockchain, which can be equally transmitted and viewed by multiple transaction parties. It can be.

Next, step (d) is a process in which the transaction management unit 130 of the platform providing server 100 creates a temporary transaction channel online with a transaction module based on the corresponding transaction certificate.

In addition, trade transaction parties can access the temporary transaction channel through their own user terminal 10.

Additionally, the transaction module can be provided in the temporary transaction channel through software installed on the user terminal 10. Such a transaction module may be provided in the form of a transaction service so that each trade transaction party can enter into mutual transaction terms through the user terminal 10 and perform transaction confirmation and modification online.

Accordingly, parties to a trade transaction can use the transaction module to negotiate and confirm trade transaction terms, transaction details, transaction amount, transaction date, etc.

In step (e), the transaction management unit 130 confirms that a transaction reservation has been made between a plurality of user terminals 10 through the transaction module, updates the transaction certificate, and registers and distributes it on the blockchain.

In this process, the transaction management unit 130 receives transaction data containing information about the transaction details concluded from the transaction module and updates it in the transaction certificate. Accordingly, the updated transaction certificate is registered and distributed on the blockchain.

Figure 4 is a diagram showing the detailed process of step (e) in the method of providing a trade transaction authentication platform according to an embodiment of the present invention.

As shown in FIG. 4, in this embodiment, step (e) may include steps (e-1) and (e-3) in detail.

Step (e-1) is a process in which the transaction module generates transaction data based on transaction details concluded between a plurality of user terminals 10 participating in the temporary transaction channel.

Such conclusion data may include information such as trade transaction conditions, transaction details, transaction amount, and transaction date.

Step (e-2) is a process in which the transaction module transmits transaction data to the transaction management unit 130. In this process, the transaction module transmits the transaction data generated in step (e-1) to the transaction of the platform providing server 100. It is transmitted to the management unit 130.

And in step (e-3), the transaction management unit 130 updates the transaction certificate based on the transaction data and registers and distributes it on the blockchain.

A trade transaction contract is concluded through the above process, and the transaction parties search for identification codes assigned to various information included in the transaction data through the user terminal 10 owned by them, thereby identifying the items in the complex trade supply chain. Tracking and management can be improved.

Afterwards, in step (f), the transaction management unit 130 may perform a process of closing the temporary transaction channel.

Meanwhile, this embodiment may further include additional processes that can be performed in addition to the steps (a) to (f) described above.

Figure 5 is a diagram showing additional processes that can be additionally performed in the method of providing a trade transaction authentication platform according to an embodiment of the present invention.

As shown in Figure 5, this embodiment further includes steps (g) and (h) performed after step (f), and steps (ex) performed between steps (d) and (e). can do.

Step (g) is a process in which the transaction management unit 130 compares the transaction certificates that can be viewed on each of the plurality of user terminals 10.

That is, after the transaction management unit 130 closes the temporary transaction channel in step (f), the transaction management unit 130 can perform a verification process to promote the transaction.

To this end, the transaction management unit 130 compares information on transaction certificates transmitted to each user terminal 10 owned by trade transaction parties. Since the transaction certificate requested and transmitted from each user terminal 10 includes information distributed on the blockchain, the transaction management unit 130 can determine whether the transaction certificate is forged or manipulated.

In step (h), the transaction management unit 130 confirms that the transaction certificates that can be viewed on each of the plurality of user terminals 10 have information that matches each other.

Then, the transaction management unit 130 updates the product arrival start information in the transaction certificate and registers and distributes it on the blockchain.

In addition, step (ex), performed between steps (d) and (e), is a process in which the transaction module collects shipping rights provided by the shipowner terminal 20 owned by the shipowner of the trade ship and provides them to a temporary transaction channel. .

In other words, the transaction module can provide the user terminal 10 with the shipping rights of a trade ship for transporting goods during the trade transaction process on a temporary transaction channel, and the trading parties do not need to separately proceed with a contract with the shipowner who owns the trade ship. Can increase convenience in the trade transaction process

To this end, before step (ex), processes for collecting shipping rights in advance from the shipowner terminal 20 owned by the shipowner may be included.

Figure 6 is a diagram showing a series of processes for issuing a shipping ticket and providing it to a transaction module in the method of providing a trade transaction authentication platform according to an embodiment of the present invention.

As shown in FIG. 6, steps (pre1) to (pre4) may be performed before step (ex).

In the (pre1) step, the shipping rights management unit 140 of the platform providing server 100 performs a trade ship registration procedure for the ship owner terminal 20.

That is, prior to the shipping rights collection process, the platform providing server (100) will proceed with the registration process for the trading vessel, and the shipowner who owns the trading vessel will receive information provided by the platform providing server (100) through the shipowner's terminal (20) that he or she owns. You will fill out the registration form required by the software.

At this time, the trade ship registration form may include items to collect load capacity information of the trade ship.

After registration of the trade vessel is completed, a (pre2) step is performed in which the shipping rights management unit 140 receives a shipping right provided from the ship owner terminal 20 for the trade vessel registered in the (pre1) step.

Here, between the (pre1) step and the (pre2) step, a (pre1.1) step in which the shipping rights management unit 140 receives a request for issuance of an NFT (Non-Fungible Token) for the shipping right from the ship owner terminal 20, An additional step (pre1.2) in which the shipping right management unit 140 issues a shipping right in the form of an NFT based on the loadable capacity of the corresponding trade ship and transmits it to the ship owner terminal 20 may be additionally performed.

In other words, ship owners can register their trade ships on the platform providing server 10 and request issuance of shipping rights as NFTs. Accordingly, the platform providing server 100 issues NFTs according to the loadable capacity of the registered trading ship and transmits them to the ship owner terminal 20, and the issued NFTs can be used as shipping rights.

And shipping rights in the form of NFT may include information such as sales start date, number of shipping rights sold, sales end point, and expiration date.

In the subsequent (pre3) stage, the shipping rights management unit 140 creates an identification means for the received shipping rights. The identification means for the shipping right may be a QR code, like the identification means for the transaction certificate described above, but is not limited thereto.

Next, in step (pre4), a process is performed in which the shipping rights management unit 140 transmits the identification means for the shipping rights to the transaction module.

Afterwards, the transaction module can provide the identification means of the shipping right received in step (pre4) to the temporary transaction channel in step (ex).

Meanwhile, in the case of general trade transactions, ship owners who own trade ships often load more cargo than can be loaded in order to prevent losses arising from reservation cancellations by bookers, leading to the possibility of overbooking. There is.

This can not only affect the stability of the ship and the delivery status of logistics, but also brings about the problem of lowering mutual trust with customers.

However, in this embodiment, a separate resell market can be operated within the software provided by the platform providing server 100, and in this case, the transaction party can resell the shipping rights paid in NFT through the resell market instead of canceling the reservation. The authority to do so may be granted.

Therefore, the transaction party can respond by reselling and transferring the shipping rights, and the present invention has the advantage of increasing profits for both ship owners and NFT shipping rights buyers.

In addition, since the number of NFT shipping rights already issued by the shipowner is limited, the overbooking problem can be naturally solved. In other words, even if the person making the reservation does not order the cargo, the burden will not be passed on to the shipowner.

Meanwhile, as described above, the transaction party may be granted the right to resell the shipping rights paid in NFT through the resell market instead of canceling the reservation, but in a situation where the shipping rights are not resold within the validity period, the transaction party Unfavorable results may occur.

Therefore, in order to prevent such a situation, at the point when the transaction party registers the shipping right for sale in the resale market, the ship owner may be given the authority to issue an overbooking shipping right for the corresponding shipping right.

In this case, the shipping right management unit 140 receives a request for issuance of an NFT for an overbooking shipping right from the ship owner terminal 20, and issues an overbooking shipping right according to the request.

In addition, in the resell market operated by the platform providing server 100, the resale shipping right registered by the transaction party who purchased the shipping right and the overbooking shipping right reissued by the ship owner can be exposed at the same time.

Accordingly, other users who wish to purchase a shipping right can select and purchase either a resale shipping right or an overbooking shipping right.

However, in the case of purchasing an overbooked shipping right, the transaction party who pre-purchased the shipping right has not yet completely decided to give up ownership of the resale shipping right, so there is a possibility that the previous transaction party may still use the shipping right. .

Therefore, on the condition that the new buyer bears this risk, the platform providing server 100 can set a policy for the resell market so that overbooked shipping rights are sold at a lower price than resale shipping rights.

And when a new buyer purchases an overbooking shipping right, the shipping rights management unit 140 notifies the user terminal 10 of the previous transaction party that the overbooking shipping rights have been sold, and deregisters the shipping rights registered in the resale market. You can then give permission to proceed with the refund process.

Accordingly, if the previous transaction party has proceeded with the refund procedure for the corresponding shipping right, the new buyer can become the first user of the corresponding shipping right because there is no possibility of overbooking the overbooked shipping right.

As described above, the preferred embodiments according to the present invention have been examined, and the fact that the present invention can be embodied in other specific forms in addition to the embodiments described above without departing from the spirit or scope thereof is recognized by those skilled in the art. It is self-evident to them. Therefore, the above-described embodiments are to be regarded as illustrative and not restrictive, and thus the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.
