{METHOD OF OPERATING ART TRADING PLATFORM THAT ADJUSTS APPRAISAL LEVEL OF ART WORKS ACCORDING TO TRANSACTION HISTORY OF SELLER AND BUYER AND USES ESCROW ACCOUNT TO ENSURE TRANSACTION SAFETY}

The present invention relates to a method of operating an art trading platform that adjusts the appraisal grade of artwork according to the transaction history of sellers and buyers and ensures transaction safety using an escrow account.

As platform business has become more active recently, various business models are being digitized and a large number of users are being recruited to increase the valuation of platform apps and web platforms.

In particular, as consumer purchases move from offline stores to online platforms, the market size of online transaction platforms (open markets, etc.) is increasing day by day, and consumers exchange information through various communities and purchase everything from daily necessities to expensive luxury goods online. A trading platform is being used.

Meanwhile, since the art trading platform is a specialized field, unlike general trading items where various information can be collected from various communities, individual tastes and trends in the art industry are reflected in the transaction, and the trading parties are able to determine whether the exhibited items are genuine or fake. They want to have the status and value notarized accurately, and especially when expensive exhibits are being traded, they want to be guaranteed transaction safety, including the purchase price and delivery of the goods.

However, the conventional art trading platform does not accurately reflect the above-mentioned needs of the transaction parties, resulting in low user satisfaction, and a solution to this problem is required.

The problem that the present invention seeks to solve is to provide a method of operating an art trading platform that adjusts the appraisal grade of an artwork according to the transaction history of the seller and buyer and ensures transaction safety using an escrow account.

The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned can be clearly understood by those skilled in the art from the description below.

The operating method of the platform of the present invention to solve the above-described problems includes the steps of a seller terminal transmitting seller information and information on exhibition artworks to the main server; A buyer terminal transmitting buyer information and purchased artwork information to the main server; The main server transmits a list of works of art to the buyer terminal, and the buyer terminal transmits selected works of art selected from the list of works of art to the main server, wherein the main server matches the seller information and the buyer information to make a match. Calculate the information matching index of the seller and the buyer to the extent that it matches the information of the displayed artwork and the information of the purchased artwork and calculate the object matching index of the seller and the buyer to the degree of matching, and calculate the information matching index of the seller and the buyer and the object of the seller and the buyer. It may be characterized by adding up the art matching indices and generating a list of art works only with art pieces that are above a certain value.

It may further include the step of the main server transmitting the appraisal result of the selected artwork to the seller terminal and the buyer terminal.

It may further include the step of the seller terminal and the buyer terminal transmitting a transaction approval for the selected artwork to the main server.

The main server may further include a step of confirming the purchaser's deposit in the escrow account.

It may further include the step of the main server receiving delivery confirmation from the buyer terminal and then transferring the deposited amount in the escrow account to the seller's account.

The operating method of the platform of the present invention has the advantage of analyzing information on sellers and buyers and further curating customized exhibition artworks for transaction parties by reflecting the latest trends in the art industry.

In addition, the operating method of the platform of the present invention has the advantage of being able to accurately appraise and notarize the authenticity and value of the artwork based on various data once the artwork to be traded is confirmed.

Furthermore, in the operating method of the platform of the present invention, the artwork is delivered after the purchaser's deposit of the purchase price is confirmed using an escrow account, and the purchase price is remitted to the seller after the delivery of the artwork is confirmed, thereby actively ensuring the safety of the transaction. It has the advantage of eliminating transaction risk through collateral.

Figure 1 is a flowchart showing the process of the operating method of the platform of the present invention, and Figure 2 is a block diagram showing the system used in the operating method of the platform of the present invention.

The platform operation method 1000 of the present invention can be performed within a system including a seller terminal 10, a buyer terminal 20, a network 30, and a main server 40.

The seller terminal 10 and the buyer terminal 20 may be terminals that provide a web page, app page (app list), program, or application related to the operating method 1000 of the platform of the present invention. Sellers can display artwork scheduled for sale on the platform, and buyers can purchase the artwork displayed by the seller after receiving a curated, certified appraisal.

In this case, the seller terminal 10 and the buyer terminal 20 may be implemented as computers capable of accessing and connecting to the main server 40 at a remote location through the network 30.

In detail, the seller terminal 10 and the buyer terminal 20 are wireless communication devices, including navigation, PCS (Personal Communication System), GSM (Global System for Mobile communications), PDC (Personal Digital Cellular), and PHS (Personal Handyphone System). ), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal, smartphone It may include all types of handheld wireless communication devices such as (smartphone), smartpad, tablet PC, etc., as well as wired communication devices such as general desktop PCs. It is not limited to this.

The network 30 refers to a connection structure capable of exchanging information between each node, such as the seller terminal 10, the buyer terminal 20, and the main server 40. Examples of such networks include RF, 3GPP ( 3rd Generation Partnership Project) network, LTE (Long Term Evolution) network, 5GPP (5rd Generation Partnership Project) network, WIMAX (World Interoperability for Microwave Access) network, Internet, LAN (Local Area Network), Wireless LAN (Wireless) Includes, but is not limited to, Local Area Network, WAN (Wide Area Network), PAN (Personal Area Network), Bluetooth network, NFC network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, etc. does not

The main server 40 is a server of an operating platform operated by an administrator of an art trading platform, and may be a server that provides web pages, app pages, programs, or applications related to the platform operating method 1000 of the present invention.

The operating method 1000 of the platform of the present invention includes the steps 100 of transmitting seller information and exhibition artwork information from the seller terminal 10 to the main server 40; A step (200) of the buyer terminal 20 transmitting buyer information and purchased art work information to the main server 40; A step (300) in which the main server 40 transmits a list of works of art to the buyer terminal 20, and the buyer terminal 20 transmits selected works of art selected from the list of works of art to the main server 40; A step (400) of the main server (40) transmitting the appraisal result of the selected artwork to the seller terminal (10) and the buyer terminal (20); A step (500) of the seller terminal 10 and the buyer terminal 20 transmitting a transaction approval for the selected artwork to the main server 40; The main server 40 confirms the buyer's deposit in the escrow account (600); It may include a step 700 in which the main server 40 receives delivery confirmation from the buyer terminal 20 and then transfers the deposited amount in the escrow account to the seller's account.

In the step 100, where the seller terminal 10 transmits the seller information and information on the artwork on display to the main server 40, the seller registers his or her information on the platform and simultaneously provides information on the artwork he or she wishes to sell and uploads it to the platform. This may be a step.

In this case, the seller information may include, but is not limited to, the number of past sales of the seller, the average selling price, and the type of art sold (nationality, completion time, subject, painting style, etc. of the sold art). Additionally, the information on the displayed artwork may include, but is not limited to, the desired selling price and the type of displayed artwork (nationality, completion period, theme, painting style, etc. of the currently displayed artwork).

In the step 200, where the buyer terminal 20 transmits buyer information to the main server 40 and transmits information on the artwork to be purchased, the buyer registers his or her information on the platform and simultaneously provides information on the artwork he or she wishes to purchase to the platform. This may be the stage where you are surfing the web.

In this case, buyer information may include, but is not limited to, the number of past purchases by the buyer, the average purchase price, and the type of art purchased (nationality, completion time, subject, painting style, etc. of the purchased art). In addition, the information on the artwork to be purchased may include, but is not limited to, the desired purchase price and the type of artwork to be purchased (nationality, completion date, subject, painting style, etc. of the artwork currently being purchased).

The step (300) in which the main server (40) transmits a list of artworks to the buyer terminal (20) and the buyer terminal (20) transmits the selected artwork selected from the artwork list to the main server (40) is the main server (40) of the platform. ), a list of artworks with high similarity (a list of artworks with high similarity among multiple displayed artworks uploaded from multiple sellers) is created by matching the seller information and displayed artwork information on the seller side with the buyer information and purchased artwork information on the buyer side. This may be a step in which the artwork is generated and transmitted to the buyer, and the buyer selects the artwork he/she wants to purchase from the artwork list and transmits it to the main server 40 of the platform.

As an example, the main server 40 matches the number of sales/purchases, average sales/purchase prices, and types of art sold/purchased in the seller information and buyer information, and compares them to index the degree of match (e.g., each category The "information matching index of sellers and buyers" can be calculated by multiplying the weight of each category based on the number of matches within a certain range and adding up the sum, and the desired sales/sales of information on displayed artworks and information on purchased artworks can be calculated. The purchase price matches the types of art pieces displayed/purchased, compares them, and indexes the degree of matching (for example, a natural number calculated by multiplying the number of matches within a specific range for each category by the weight for each category and adding them up) to determine the “seller” price. You can calculate the "matching index of the buyer's target art work" and create a list of art works only with art pieces for which the sum of the two indices is greater than a certain value.

In contrast, in the platform operation method 1000 of the present invention, the main server 40 can predict the buyer's satisfaction index for the art work list using artificial intelligence.

Artificial Intelligence (AI) is a field of computer engineering and information technology that realizes human learning ability, reasoning ability, perception ability, and natural language understanding ability through computer programs. In particular, supervised learning, which is used in the most fields of artificial intelligence, is a method of predicting future values using training data containing the correct answer (Label).

For reference, machine learning can be defined as a methodology that gives computers the ability to learn on their own without being explicitly programmed. This is a method that allows a program to learn data patterns on its own based on data. Machine learning is divided into supervised learning and unsupervised learning, depending on whether the correct answer is specified in the data required for learning. Classification divides the data into a finite number of categories depending on the purpose of use, and continuous learning. It is divided into Regression, which maps to values, Clustering, which groups similar data, and Dimension Reduction, which maps multi-dimensional data into representative lower dimensions.

Deep learning is one of the machine learning techniques that has dramatically improved the performance of machine learning, which had been stagnant for a while. Deep learning is a methodology based on the Artificial Neural Network (ANN) algorithm that mimics the overlap of synapses in the human brain structure. , The deep learning structure is a deep neural network (DNN) with multiple hidden layers between the input layer and the output layer, and a filter required for factor extraction in front of the hidden layer. It can include a convolutional neural network (CNN) that learns filters together, and a recurrent neural network (RNN) that can process time series data by stacking artificial neural networks at each time. Here, the high performance of the deep learning model is explained in two ways. First, the Inkyung Neural Network is a universal approximator that can approximate all types of functions by overlapping the weighted sum of the functions in each layer, if sufficiently general data is given. Data can be simulated with high accuracy. Second, in order to properly classify data, it is important to properly extract factors representing the data, and optimal factors can be extracted through filter learning using a convolutional neural network. In addition, deep learning is a developed form of a model in the field of artificial intelligence called a neural network, and the internal layer (hidden layer) of the hierarchical artificial neural network is composed of several stages. Recent deep learning models have increased internal layers, so the number of weights (meaning connection strength) connecting nodes can reach up to billions.

As an example, the main server 40 asks the buyer to evaluate the satisfaction index for the list of artworks, and then collects seller information, information on displayed artworks, buyer information, information on purchased artworks, and a list of artworks derived accordingly as feature data from the past database. After learning artificial intelligence with a dataset that uses the buyer's satisfaction information on the list of art works as labeling data, the current seller information, information on displayed works of art, buyer information, information on purchased works of art, and the list of works of art derived accordingly are used. The buyer's satisfaction index can be predicted by inputting it into the learned cognitive intelligence.

Accordingly, in order to set a matching index when the buyer's satisfaction index is predicted to be below a certain value, different weights are set for each category matched in the seller information and buyer information, and each of the displayed artwork information and purchased artwork information is set differently. You can also curate a revised list of artworks by setting different weights for each category.

The step 400, in which the main server 40 transmits the appraisal result of the selected artwork to the seller terminal 10 and the buyer terminal 20, proceeds with the appraisal of the selected artwork selected by the buyer and sends the appraisal result to the seller terminal 10. This may be a step of transmitting to the purchaser terminal 20.

In this case, the appraisal result may include, but is not limited to, the appraised value and authenticity of the selected artwork. Meanwhile, in the platform operation method 1000 of the present invention, the main server 40 can ensure the reliability and fairness of the appraisal results by operating its own appraisal group or through external requests such as the Korea Art Appraisal Board or the Korea Art Promotion Agency.

In the step 500, where the seller terminal 10 and the buyer terminal 20 transmit approval for the transaction of the selected artwork to the main server 40, the seller and the buyer confirm the appraisal results and then confirm the transaction conditions, including the transaction price. This may be the next step to approving the final transaction. In this case, the transaction conditions confirmed by the seller and buyer may be transmitted to the main server 40. In addition, the main server 40 may provide a chat room that supports chatting between the seller terminal 10 and the buyer terminal 20 at the request of at least one of the seller terminal 10 and the buyer terminal 20, and the chat room By converting the data into a blockchain and recording it in a database, it can be used as evidence if legal issues related to transactions arise in the future.

In step 600, where the main server 40 confirms the buyer's deposit in the escrow account, after the transaction is approved, the main server 40 creates an escrow account, transmits it to the buyer terminal 20, and then deposits the transaction amount. This may be a request step.

The main server 40 receives delivery confirmation from the buyer terminal 20 and then transfers the deposit from the escrow account to the seller account (700). After the buyer receives the artwork, confirmation thereof is sent to the main server of the platform (40). ), this may be a step in which the main server 40 transfers the deposit amount from the escrow account to the seller's account as a condition for remittance.

That is, in the operating method 1000 of the platform of the present invention, the safety of the transaction can be ensured by using an escrow account to ensure that payments are delivered while the rights/obligations of both parties are confirmed and fulfilled. Meanwhile, the seller account is included in the transaction conditions and may be an account pre-stored in the main server 40 when the transaction is approved.

Hereinafter, a process in which the main server 40 conducts an appraisal of a selected artwork will be described in a modified example (not shown) of the platform operation method 1000 of the present invention. The main server 40 can calculate the appraisal progress grade by reflecting the seller information, information on the artwork on display, buyer information, information on the artwork purchased, and the importance index. In this case, the importance index can refer to the number of times keywords (name of the work of the Select artwork, artist of the Select artwork) for the Select artwork were searched on the web (search engine) outside the platform during a specific period in the past from the present before the start of the appraisal. You can check the degree of issue and importance of the selected artwork. The higher the importance index, the higher the appraisal progress level needs to be.

Meanwhile, the higher the value of the appraisal progress grade, the more precise and expensive the appraisal can be. For example, if the appraisal progress level is low, the appraisal can only be carried out by the platform's own appraisal team, and if the appraisal progress grade is medium, the appraisal is performed by requesting the platform's own appraisal team and a single external agency to conduct each appraisal. Even if the difference in the appraised value of the result is more than a certain value and the authenticity is different, the appraisal result can be provided to the seller and the buyer. If the appraisal progress grade is high, the appraisal is performed by requesting multiple external agencies and each appraisal result is evaluated. Appraisal can be performed repeatedly by changing multiple external agencies until the difference in appraised value is less than a certain value and the authenticity is the same.

Specifically, the main server 40 determines that (1) the absolute value of the difference between the past average selling price of the seller information and the desired selling price of the displayed artwork information is less than a first specific value, and the difference between the past average purchasing price of the buyer information and the purchased artwork information If the absolute value of the difference in the desired purchase price is less than the first specific value, the first grade appraisal can be performed if the number of past sales in the seller information is more than the second specific value, and the number of past sales in the seller information is the second specific value. If the importance index is less than the third specific value, a first-grade appraisal can be performed, and if the importance index is greater than the third specific value, a second-grade appraisal can be performed. If the transaction is for an artwork in a price range that has been traded frequently between the seller and the buyer, and the seller's number of past sales is high or the importance index is low, the reason for proceeding with a low-grade appraisal is that the seller has built up credit by selling a lot of artwork in that price range. Even if the lyrics appraisal result is inaccurate, both the seller and the buyer have the ability to determine the appraisal result, so the appraisal price is lowered and a lower-grade appraisal is performed, but if the importance index is high, a higher-level appraisal is conducted ( The seller's credit rating is secured and the number of purchases by the buyer is not considered).

However, in the modified example of the platform operation method 1000 of the present invention, in the above-described case, the number of past sales of the seller information is excluded and the number of past purchases of the buyer is taken into consideration in order to more actively protect buyers with high transaction risk. It may be possible. In other words, rather than setting an appraisal grade based on the seller's creditworthiness, the appraisal grade can be set based on the buyer's transaction experience. In this case, in a modified example of the platform operation method 1000 of the present invention, the absolute value of the difference between the past average selling price of the seller information and the desired selling price of the exhibition art information is less than the first specific value, and the past average purchase price of the buyer information is less than the first specific value. If the absolute value of the difference between the desired purchase price of the purchased art information is less than the first specific value, and the number of past purchases in the buyer information is greater than the second specific value, a first-class appraisal can be performed, and the number of past purchases in the buyer information If is less than the second specific value, a first-class appraisal can be performed if the importance index is less than the third specific value, and if the importance index is greater than the third specific value, a second-class appraisal can be performed.

In addition, the main server 40 determines that (2) the absolute value of the difference between the past average selling price of the seller information and the desired selling price of the exhibition art work information is greater than or equal to a first specific value, and the past average purchasing price of the buyer information and the desired selling price of the purchased art work information If the absolute value of the difference in purchase price is less than the first specific value, a second-grade appraisal can be performed if the number of past purchases in the buyer information is more than the second specific value, and the number of past purchases in the buyer information is less than the second specific value. If so, you can proceed to level 3 appraisal. If it is not an art piece in a price range that has been traded frequently by the seller, but is a piece of art in a price range that has been traded a lot by the buyer, and a certain number of past purchases have been secured, it is given a relatively medium grade in recognition of the experience that can be used to determine the appraisal result of a buyer with a high transaction risk. Otherwise, a higher level appraisal is performed (the number of sales by sellers who do not have a high transaction risk is not considered and a mid-level appraisal is conducted, so the stability of the basic transaction is ensured without necessarily considering the importance index). secured).

In addition, the main server 40 determines that (3) the absolute value of the difference between the past average selling price of the seller information and the desired selling price of the exhibition art work information is less than a first specific value, and the past average purchasing price of the buyer information and the desired selling price of the purchased art work information If the absolute value of the difference between the purchase price is greater than or equal to the first specific value, and the absolute value of the difference between the past average selling price in the seller information and the desired selling price in the exhibition art information is greater than or equal to the first specific value, and the past average purchasing price in the buyer information is equal to the purchased artwork If the absolute value of the difference between the desired purchase price of the information is greater than or equal to the first specific value, if the importance index is less than the third specific value, a fourth-grade appraisal may be performed, and if the importance index is greater than the third specific value, a fifth-grade appraisal may be performed. You can. Because a buyer with a high transaction risk has little history of trading art works in that price range, a high-grade appraisal is performed. Furthermore, if the importance of the artwork in question is high, a highest-grade appraisal is performed (buyers with a high transaction risk are For active protection, a high-grade appraisal is performed without considering the number of sales by the seller or the number of purchases by the buyer, and if the importance is high, the highest-grade appraisal is performed).
