Description

Management device and management method {APPARATUS AND METHOD FOR MANAGING}

The present invention relates to an apparatus and method for managing a transaction occurring between a seller and a buyer, or managing transaction information generated through the transaction.

As the network develops, the number of data broker companies that collect and process big data and then resell or utilize big data to earn profits is increasing. The scale is also gradually growing.

A data broker collects data from personal information providers, finds out individual characteristics through big data analysis, and sells the found information to service providers. For example, the information may be sold to service providers in various fields such as advertisement, recommendation, and policy promotion, and may be used for product recommendation such as advertisement marketing, real estate policy, and travel/clothing based on the information.

However, in order to use a specific service, users (i.e., personal information providers) who subscribe to a website that provides the service, download an application, or subscribe to insurance, credit card, electronic financial service, etc. In most cases, it is not known how the information is collected and used according to the contract, which instills anxiety in the personal information provider. For example, according to the 2014 report of the World Economic Forum, users (i.e., providers of personal information) have a high level of anxiety about personal information infringement. It has been investigated that the reliability is low.

As such, the user who is the owner of the personal information does not have the initiative to use personal information, but the problem of leakage and illegal use of personal information continues to be on the side of collecting personal information. In other words, there is a problem of conflict of interest among big data collectors. As a representative conflict, there is a conflict of interest in the opt-in method. Looking at cases of disputes over the past few years related to privacy infringement issues, in particular, the unauthorized collection of personal location information by big data collectors (ie, data brokers) has become an issue of conflict.

With regard to location information, a problem has been raised about the optout method already adopted in the United States. The opt-out method is a method in which service is blocked after refusal to receive, and the US has supported the opt-out method as it fundamentally prioritizes industrial promotion and promotes structuring of'privacy business'.

However, after Google's street view incident in 2010, Google has applied an opt-in method for Android-based location information. And, unlike the United States, the European Union (EU) adheres to the opt-in method in principle. In the case of the European Union, when the original draft'Data Protection Rule' was released in January 2012, the collection, leakage and corruption of personal information are strictly regulated, such as collecting up to 0.5% of global annual sales in case of violation of prior application.

Based on this background, it is expected that the future big data-related market will turn into a big trust-related market due to the destructive characteristics of Big Trust. For example, the destructive features of Big Trust are the user's control base, relation-first base, the benefits of privacy defense, the electoralization of users, defense and expansion of the personal economy, transparent collection and use, opt-in recommendation, self-analysis based self-analysis. It includes a proven consumer profile, an individual image, single sign-on, synergy of interests, rebalancing of interests, building trust, and destroying the market power of the Internet majors.

As such, as the mobile Internet as well as the wired Internet is developed, the collection and use of big data is increasing, and users' anxiety about the transaction of the collected big data is increasing, and fraud is also increasing. A technology to provide and utilize as a basis is required. In other words, the user control-based transfer of ownership (i.e., initiative) of personal information from the side that collects data (e.g., big data collection device or data broker) to the side that provides the data (e.g., the user who owns the personal information) Personal information utilization technology is required.

In addition, in order to ensure the reliability of personal information utilization technology, personal information must be securely protected.

In Korean Patent Publication No. 2018-0095912, there is a technology for updating reputation scores related to various nodes by reading subscription transactions, purchase transactions, and verification transactions from a distributed ledger. However, measures to utilize personal information and measures to protect personal information are insufficient.

1 is a block diagram showing a management apparatus according to the present invention.

The management device 100 illustrated in FIG. 1 may include a transaction unit 110, a collection unit 130, and an analysis unit 150.

The transaction unit 110 may process a product transaction between a seller and a buyer. The'product' may include a physical product having a shape, a code commonly used online, a service provided by a seller, and the like. A product transaction may be made through a buyer paying a purchase cost for the product. At this time, a virtual asset may be used as a purchase cost. Virtual assets may include virtual currency such as bitcoin or real cash (online cash) stored as digital data in a bank.

When both parties meet in person to directly exchange goods and cash, the transaction unit 110 has no way of knowing that fact. Accordingly, a transaction of a product made in the present specification may represent a transaction that can be grasped by the transaction unit 110. As an example, the'product transaction' described in the present invention may mean a product transaction between a first terminal used by a seller and a second terminal used by a buyer. Accordingly, depending on the situation, the'seller' described in this specification may represent the first terminal, and the'buyer' described in the present specification may represent the second terminal.

The transaction unit 110 may be provided with a communication module for wired or wireless communication with the user terminal 10 and the financial server 90. The user terminal 10 may include a first terminal for receiving payment of a virtual asset through the transaction unit 110 or requesting payment of the virtual asset, and a second terminal for paying the virtual asset through the transaction unit 110.

The transaction unit 110 has information on virtual assets possessed by each user (seller, buyer), and may increase or decrease the amount of virtual assets possessed by each user according to payment of the virtual assets.

The transaction unit 110 may provide the user terminal 10 with an environment in which virtual assets can be traded. The transaction unit 110 may be provided with various authentication means so that transactions between the user terminals 10 can be normally performed.

2 is a block diagram showing the transaction unit 110. 3 is a block diagram showing the collection unit 130 and the analysis unit 150.

The transaction unit 110 may be provided with a code unit 111, a payment unit 113, and a notification unit 115.

The code unit 111 may provide a QR code (Quick Response Code) related to the product to the seller. The QR code may include the seller's identification information and the product's identification information. The code unit 111 may transmit a QR code to the payment unit 113 where payment is made.

When the buyer recognizes the seller's QR code using the second terminal and pays the cost of the product using the QR mode, the payment unit 113 can obtain payment information related to the payment of the product cost from the second terminal. .

The payment unit 113 may transmit payment information to a financial server 90 such as a PG, VAN, credit card company, or bank, and may request approval for the payment information. If the payment information is normal, the financial server 90 may approve the payment information.

When payment information is approved from the financial server 90, the payment unit 113 may transmit the payment information to the collection unit 130.

If the payment unit 113 does not receive approval from the financial server 90 for a set time, or if the approval fails, the payment information may be discarded or returned to the second terminal.

When payment information is transmitted to the collection unit 130 by the payment unit 113, the collection unit 130 may conclude a smart contract between the seller and the buyer based on the payment information.

The notification unit 115 may obtain payment information from the payment unit 113. When the information on the execution of the smart contract is obtained from the collection unit 130, the notification unit 115 may specify the seller and the purchaser using the payment information, and notify the specified seller and purchaser of payment completion.

According to the transaction unit 110 of the present invention, only when the financial server 90 approves and the smart contract of the collection unit 130 is normally performed, the payment for the product transaction can be completed.

The collection unit 130 may collect transaction information of products traded through the transaction unit 110. Transaction information may include various personal information such as payment information related to payment of expenses, identification information of a seller, identification information of a purchaser, and so on. Therefore, transaction information needs to be secured. In addition, since secured transaction information has high reliability, it can be used as a variety of marketing materials.

The collection unit 130 may be provided with a block chain database, a decentralized application (DAPP) for distributed storage of collected transaction information, a block chain server, and the like.

In order to protect transaction information, the collection unit 130 may distribute and store transaction information using a block chain.

With the advent of encryption technology such as blockchain, interest in virtual assets based on encryption technology is increasing. Among them, the most notable virtual assets are Bitcoin, and in addition, Ethereum, Ripple, Dash, and Litecoin are in service or are already in service. .

In the past, various and numerous cryptocurrency-based currencies have been used by web service companies under the name of'Cash'. In general, in e-commerce, electronic money, which is the basis of transactions, is widely used online, and credit cards currently used as payment methods in e-commerce are also digitalized and virtualized, and a means to conduct credit transactions without immediate payment of real money. As it is used, it can be said that the circulation structure of credit card companies, banks, and affiliated stores is completed and is included in the category of electronic money.

Therefore, it is judged that the reason why virtual assets, which are a kind of existing electronic money, are rapidly receiving attention is due to differences in operation methods such as distributed storage.

Virtual assets are made by a distributed network timestamp server based on a peer-to-peer network (P2P) in the transaction method. Virtual assets are traded using public key cryptography, and as the distributed ledger is managed through each node, it is possible to operate without central authority or bank unlike the existing real money. There are significant differences.

This remittance method using a virtual asset has the advantage of being extremely low in risk and inexpensive usage fees as it can be used without information such as a card number, expiration date, and CCV number required for credit card payment.

Currently, among virtual assets that can be settled in kind, in the case of Bitcoin, transaction details between parties are stored and collected in an electronic wallet of a blockchain as a distributed ledger.

The electronic wallet can be created by installing a virtual asset client program provided by a virtual asset developer on the terminal, or by signing up for a virtual asset exchange such as'www.bithumb.com'. The created electronic wallet can be called a kind of virtual asset account, and the creation of the electronic wallet can be made by a combination of numbers and English case, such as a public address of 32 bytes or more. For example, the electronic wallet may be in the form of '16YxMgbMydAtgFWQB5' and'jP8rh9auwpqqthJY'.

In a transaction between parties using an electronic wallet, since transactions and remittances are possible only when the electronic wallet address is recognized with each other, it is difficult for general users to use it conveniently and quickly.

In addition, in the case of Bitcoin, it can be said that it is a virtual currency that attracts attention unprecedentedly, but problems of popularization and reflection of real life remain. In fact, in the domestic situation, only transactions that buy and sell virtual assets for investment purposes are active, and are not actually used like cash in various fields. Accordingly, it can be said that the prospects for these virtual assets are diverse.

Nevertheless, virtual assets have five characteristics: transparency, immutability, low fees, borderless and fast speed. Transparency means that anyone can access the blockchain network, so that the transmission of the block in which their transaction has been made and confirmation of the transaction history is possible, and immutability means that the transaction cannot be canceled once the transaction is approved, and no one can interfere with the transaction. This indicates that fees are relatively inexpensive as there are no separate fees other than fees for moving between virtual currencies. In addition, Borderless means that you can easily send funds to any country in the world, as if it were right next door, and the fast speed is that with the straightforward and transparent nature of the blockchain, remittances happen almost instantly, typically in minutes rather than days or hours. It refers to the feature that can be checked inside.

Likewise, the collection unit 130 of the present invention uses a block chain to store geopolitical information, so that the characteristics of transparency, immutability, low fees, borderlessness, and high speed can be given to transaction information as it is.

Transaction information safely stored due to transparency and immutability may be analyzed by the analysis unit 150.

The analysis unit 150 may include a verification unit 159, a sales analysis unit 151, a first purchase analysis unit 153, and a second purchase analysis unit 155.

The verification unit 159 may obtain transaction information and a smart contract from the collection unit 130 and verify the transaction information using the smart contract. When it is determined that the transaction information is normal through the comparison of the transaction information and the smart contract, the detection unit may transmit the transaction information to the sales analysis unit 151 and the first purchase analysis unit 153.

The sales analysis unit 151 of the analysis unit 150 may grasp basic data that can be used for marketing by a seller through analysis of transaction information. For example, through analysis of transaction information targeting a specific seller, basis information for a buyer to commonly purchase product A from a specific seller may be identified. This information can be used as marketing data or planning data that the seller can apply to other products by grasping the characteristics of product A.

The sales analysis unit 151 of the analysis unit 150 may grasp and extract the basis data by using the basis data grasp model generated by machine learning using big data.

The first purchase analysis unit 153 of the analysis unit 150 may determine a purchase pattern of a purchaser through analysis of transaction information. As an example, the analysis unit 150 may use the personal information of a specific purchaser and product information purchased by the specific purchaser to determine which product a user having the personal information prefers.

The first purchase analysis unit 153 may identify and extract a purchase pattern of a purchaser using a purchase pattern identification model generated by machine learning using big data.

The second purchase analysis unit 155 of the analysis unit 150 may group a plurality of purchasers by purchase pattern by using the analysis result of the purchase pattern performed by the first purchase analysis unit 153. The second purchase analysis unit 155 may analyze data that can be used for marketing for each group. For example, the second purchase analysis unit 155 may classify a plurality of purchasers by age, income, and region. The second purchase analysis unit 155 may identify characteristics that a group of purchasers divided by age, income, and region have in common, that is, common points. The second purchase analysis unit 155 may collect or select marketing information that can satisfy the common point.

For example, if male buyers in their twenties who use store A have a game in common, the second purchase analysis unit 155 identifies a game that corresponds to a common point and provides a game-related service to male buyers in their twenties. Information can be selected, collected, and provided to the store owner of store A, that is, the seller.

Identification information of a seller corresponding to a party to the transaction information and identification information of a buyer may be obtained. For example, the transaction unit 110 may induce a seller or a buyer to directly provide their identification information through a method such as membership registration. The identification information at this time may include name, gender, phone number, address, account number, electronic wallet information, and the like.

The payment unit 113 of the transaction unit 110 may transmit the seller's identification information or the purchaser's identification information to the collection unit 130.

The collection unit 130 may be provided with a collection unit 131 and a fastening unit 133.

The collection unit 131 may generate an ID used in the block chain by using the identification information of the seller or the purchaser. Specifically, the collection unit 131 of the collection unit 130 may generate a first ID and a second ID corresponding to a hash value used in the block chain. The first ID may include identification information of the seller. The second ID may include identification information of the purchaser.

When a product transaction occurs, the transaction unit 110 may obtain the first ID and the second ID through the collection unit 131. The transaction unit 110 may perform processing of assets contained in the blockchain for the first ID and the second ID for the transaction of the product.

The fastening unit 133 of the collection unit 130 can enter into a smart contract for the seller and the buyer, respectively, when the payment information for which the buyer pays for the product is normally approved by the financial server 90. have.

The contractor 133 may enter into a first smart contract based on a block chain, which automatically executes a transaction of a product when a set condition is satisfied, to a seller.

The collection unit 130 may conclude with a buyer a second smart contract based on a blockchain that automatically executes a transaction of a product when a set condition is satisfied, apart from the one concluded with the seller.

A smart contract is a set of software codes realized on the blockchain platform, and can guarantee that the contents of the contract are automatically executed for assets contained in the blockchain when predetermined conditions are fulfilled.

In smart contracts, the means of payment for contracts and payments in return are encrypted, and the process of contract execution and verification is automated with a network, so that complex business contracts can be reduced by directly processing without interference from people who check the contract execution conditions and without additional costs. It makes it possible to safely execute contracts based on cost and trust in agreement.

Since smart contracts are written in code, they are highly likely to be strictly interpreted under literaryism, reducing the uncertainty of contract interpretation, but there is a possibility that inconsistencies in interpretation and writing errors may occur in the writing stage of programming contracts in everyday languages.

The smart contract created or created in the fastening part 133 is advantageous as the length of the code is shorter for the prevention of mismatches in interpretation and writing errors, and for strict and clear interpretation. According to the present invention, at least a first smart contract targeting a seller and a second smart contract targeting a buyer may be signed, respectively, instead of one existing smart contract in which the seller and the purchaser are two parties. According to the present invention, since one smart contract is divided into two or more, the length of the self-contained code can be significantly shortened. Short-length codes reduce ambiguity and reduce the likelihood of misinterpretation. Therefore, according to the present invention for entering into a plurality of smart contracts for a single product transaction, a later verification process can be very easy. In addition, since each of the plurality of smart contracts is distributed and stored, security can also be enhanced.

For one transaction, the first smart contract and the second smart contract may be managed (stored) in a hash value state by the collection unit 131. The first smart contract and the second smart contract may be used for verification of a product transaction made between a seller and a buyer. The verification may be performed by the verification unit 159 of the analysis unit 150 or a separate verification means.

The fastening unit 133 of the collection unit 130 may generate a plurality of module contracts in which one of the two contracting parties is a third party.

The fastening unit 133 may generate a first contract in which the remaining one of the contracting parties among the plurality of module contracts is a seller.

The fastening unit 133 may generate a second contract in which the remaining one of the contracting parties among the plurality of module contracts is a purchaser.

A plurality of module contracts including a first contract and a second contract can form a blockchain-based smart contract. At this time, the smart contract may automatically execute a product transaction when a set condition is satisfied between the seller and the buyer by the transaction unit 110 or the collection unit 130.

When a blockchain-based smart contract that automatically executes a transaction of a product when the set condition is satisfied can be concluded between a seller and a buyer, a plurality of module contracts may be generated by the collection unit 130. Specifically, the fastening unit 133 may generate a plurality of module contracts including a first contract concluded between a seller and a third party, and a second contract concluded between a purchaser and a third party.

The transaction unit 110 or the collection unit 130 may replace the smart contract by using a plurality of module contracts connected in series with one or more third parties as a link. In this case, the third party may be the transaction unit 110 or the collection unit 130 of the present invention, or may include a manager of the transaction unit 110 or a manager of the collection unit 130.

When a plurality of different third parties are provided, a plurality of module contracts may be added between the first contract and the second contract. When the third party is one transaction unit 110 or one collection unit 130, only the first contract and the second contract exist for the transaction of a specific product.

For example, when the third party is the collection unit 130 1, the first contract may form a first smart contract with the seller and the collection unit 130 as parties. The second contract may form a second smart contract with the purchaser and the collection unit 130 as parties. In this case, the collection unit 130 corresponding to the third party may be a connecting ring connecting the first contract and the second contract to each other.

In other words, the fastening unit 133 may divide a product transaction between a seller and a buyer into a plurality as follows. The fastening part 133 may intervene a third party similar to a relay agent between the seller and the buyer. The conclusion unit 133 may conclude a contract as a product transaction has been made between a seller and a third party, and may conclude a contract as a product transaction has been made between a third party and a purchaser. At this time, when a plurality of contracts are combined, as a result, it is the same as that a product transaction is made between the seller and the buyer. However, by separating one product transaction into a plurality, hacking becomes difficult and subsequent verification work may be facilitated due to the simplification of the code.

The execution unit 133 may transmit the execution information of the smart contract to the transaction unit 110.

The transaction unit 110, which has received the execution information of the smart contract, specifically the notification unit 115 may notify the seller and the buyer that payment for the product transaction has been completed (payment completed).

The collection unit 131 may distribute and store payment information that has been normally approved according to a block chain. The collection unit 131 may distribute and store the first smart contract concluded with the seller and the second smart contract concluded with the buyer according to the blockchain.

4 is a flowchart showing a management method of the present invention. The management method of FIG. 4 may be performed by the management device shown in FIG. 1.

First, the management device, specifically, the collection unit 130 may issue a first ID including identification information of a seller, and issue a second ID including identification information of a purchaser.

When a seller installs a sales app provided by the transaction unit 110 and subscribes to a member, a first ID corresponding to the seller's unique ID may be issued from the blockchain server provided in the collection unit 130. After the seller installs the sales app on the seller terminal 11, the seller signs up as a member, and a blockchain ID (hash value) may be generated in a security step (input of a pin number) to receive payment. In the blockchain ID, values entered by the purchaser at the member sign-up stage, such as name and gender, can be stored. Upon completion of membership registration, sellers can generate electronic menu boards and QR codes to sell their products or services. The timing of creating a blockchain ID is different for each blockchain company, and the values stored in the blockchain ID may all be different.

When a buyer installs a purchase app provided by the transaction unit 110 and signs up for a member, a second ID corresponding to the buyer's unique ID may be issued from the blockchain server.

Similar to creating a seller's blockchain ID, a buyer can register as a member after installing the purchase app. The blockchain ID (hash value) is generated in the security step for payment (input of the pin number), and the value entered by the buyer in the member sign-up step, such as name and gender, can be stored in the blockchain ID.

Membership registration may be performed by the transaction unit 110, and the first ID and the second ID may be generated and provided by the collection unit 130. The first ID and the second ID provided by the collection unit 130 become a block chain ID corresponding to the hash value, and may be stored in the transaction unit 110.

A seller who has completed membership registration can register his or her product. To this end, the transaction unit 110 may issue a QR code for the seller's product.

When a buyer makes a payment using a QR code issued for a specific product, payment information of the buyer who made a payment using the QR code may be obtained by the transaction unit 110.

The transaction unit 110 that has obtained the payment information may provide payment information to the financial server 90 and request approval from the financial server 90. The payment information may include information on purchaser B's purchase of product C from seller A at source D. Payment information is actually effective only when the source D, which buyer B has, is provided to seller A. The change in the payment amount D may be executed by a financial server 90 such as a credit card server or a bank server. The financial server 90 may check the integrity of the payment information and, if it is determined that there is no defect, may approve the payment of the payment amount. The payment information approval result may be provided to the transaction unit 110 through a wired or wireless communication network.

The transaction unit 110 may inform the collection unit 130 of the approval result of the financial server 90.

When payment information is approved by the financial server 90, the collection unit 130 may conclude a first smart contract for a seller and a second smart contract for a purchaser.

The fact that the first smart contract and the second smart contract are concluded may be notified to the transaction unit 110. When the fact that each contract has been concluded is received, the transaction unit 110 may notify the seller (terminal) and the purchaser (terminal) of payment completion.

The process after issuing the QR code can be summarized as follows.

The seller may be issued a QR code using a QR code system provided by the transaction unit 110. When the buyer recognizes the seller's QR code and makes payment with the buyer terminal 13 such as a mobile phone, payment information may be transmitted to the transaction unit 110. The transaction unit 110 may request approval of this information from a financial institution such as a PG, a VAN, a credit card company, or a bank. Upon approval of the financial institution, the transaction unit 110 may transmit payment information to the blockchain server. The blockchain server may transmit this information to the transaction unit 110 after signing a smart contract for the seller and the buyer, respectively. When the fact of the execution of the smart contract is obtained, the transaction unit 110 may notify the seller and the buyer of the payment completion.

When the payment of the purchaser constituting the transaction information in the blockchain is completed (payment approval is completed from the financial server 90), the payment approval information may be transmitted to the blockchain server. The blockchain server can make a second smart contract with a buyer and a first smart contract with a seller. At this time, the important point may be to enter into a smart contract for each of the seller and the buyer. That is, according to the present invention, two blockchain hash values may be generated per transaction. That is why the blockchain database can be more complete, like doubles bookkeeping, and verification can be very easy. This feature may correspond to areas that already known blockchain systems such as Ethereum or Hyperledger cannot implement.

The analysis unit 150 may analyze a purchase pattern of a purchaser using at least one of a first ID, a second ID, product information, and payment information.

The analysis unit 150 may analyze the purchaser's purchase pattern and preferred products with artificial intelligence by using the purchaser and product or service purchase information stored in the block chain. Analytical models can be created through machine learning using big data. The analysis unit 150 may directly generate an analysis model or obtain an analysis model from a separate learning means. The analysis unit 150 may use an analysis model as a function, and may take buyer information, product information, payment information, transaction information, and the like as input factors. The output value of the analysis model may include a purchase pattern of a buyer or a preferred product.
