Description

Real Estate Transaction Information Generation System for Blockchain Transaction Book Registration {SYSTEM OF GENERATING REAL ESTATE TRANSACTION INFORMATION FOR DIGITAL LEDGER USING BLOCK CHAIN SECURITY TECHNOLOGY}

The present invention relates to a real estate transaction information generation system, and more particularly, to a reliable real estate transaction information generation system for registering a blockchain transaction book.

Block chain technology can be understood as a security system used to be used for transactions using crypto currency. A blockchain transaction ledger can be understood as a collection of 'chains' following 'blocks' containing transaction information. In more detail, it refers to a data distribution processing technology in which all users participating in the network are distributed and stored. It is also called 'distributed ledger technology' (DLC) or 'public ledger' in that it is a technology shared by all network participants rather than being held by a trading entity or a specific institution. . Blockchain is a name given as a block that contains the contents of a transaction, which is a chain.

Blockchain is a technology that can be used to prevent double payments in transactions using cryptocurrencies, and uses P2P (Peer 네트워크 to Peer) networks. Each block of the blockchain transaction book contains a confirmed transaction history for a certain period of time. A block containing the transaction information is formed online, and at this time, the user who determines the transaction details is the user, and the block containing such information is transmitted to all participants in the network. Participants can check the feasibility of the transaction, and only the blocks approved by the participants are connected to the existing blockchain to make transactions. A characteristic of the blockchain is that third parties can exchange values between trading parties without guaranteeing the transaction.

Blockchain technology is not limited to transactions using cryptocurrencies. Transaction books using blockchain principles are distributed and stored on multiple user computers rather than individuals or companies, and in the case of Bitcoin, for example, a block is created, which is a bundle of transaction details once every 10 minutes. Blockchain transparently records transaction history in a book that anyone can read, and several computers using the blockchain verify this record once every 10 minutes to prevent hacking. According to the theoretical background, blockchain is understood as a technology that is almost impossible to hack, and has the advantage of guaranteeing the transparency of the transaction in that the transaction history is maintained. If such a blockchain principle is used, the transparency of information as well as the history of objects traded in e-commerce can be ensured.

On the other hand, apart from the fact that the reliability of each stage of the transaction is maintained in the transaction using the blockchain principle, there is a limitation that the evaluation of the fairness of the transaction information itself cannot be made when the initial ledger is created. In particular, when the object to be traded using a public transaction book is a high-value object, it is difficult to verify the value and property of the property when registering the transaction for the first time, for example. Have

The real estate transaction information generation system for registering a blockchain transaction book according to an embodiment of the present invention aims to provide a system for verifying a real estate sale before registering a transaction sale in the blockchain transaction book.

Hereinafter, a real estate transaction information generation system for registering a blockchain transaction book according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a system block diagram of a client server 100 in a real estate transaction information generation system according to an embodiment of the present invention.

Referring to Figure 1, the client server 100 for providing a real estate transaction information generation system according to an embodiment of the present invention is a transmitting and receiving unit 110, billing cost calculation unit 120, evaluation property information extraction unit 130, Brokerage agent information extraction unit 140, brokerage agent matching unit 150, evaluation information request unit 160, brokerage agent evaluation unit 170, compensation cost settlement unit 180, comprehensive evaluation information generation unit 190, It may include a comprehensive evaluation information storage unit 210 and a comprehensive evaluation information management unit 200.

The transceiving unit 110 may be provided to perform wired and wireless data communication with the transaction requesting user device 200 or the intermediary agent user device 300. The transceiving unit 110 may be provided to perform direct communication with the transaction requesting user device 200 and the intermediary agent user device 300 or to transmit and receive information through a communication network provided by a third communication provider.

The billing cost settlement unit 120 may be provided to transmit cost request information for providing an upload service to the transaction requesting user device 200 through the transceiver 110. The cost request information is information on the cost required to upload the real estate contract sale to the client server 100 and send it to the intermediary proxy user device 300 for evaluation of the real estate contract sale.

The cost request information may include request information regarding a means having exchange value necessary for the evaluation of a real estate contract sale. The means having exchange value is information processed by the reward bank server 400 and may be payment information in the form of money, virtual currency (or cryptocurrency), point, or token. The compensation cost information transmitted to the intermediary proxy user device 300 may also be provided as compensation information in the form of money, virtual currency (or cryptocurrency), point, or token. However, the present invention is not limited to the above, and any value transmission means that can be transmitted electronically can be used in connection with the charge request information.

The evaluation property information extraction unit 130 receives the payment payment information corresponding to the cost request information from the transaction requesting user device 200 through the transmission / reception unit 110, and then sells area information from the real estate contract sale information. It may be provided to extract. That is, when payment information regarding a means having a certain exchange value is received from the transaction requesting user device 200, information on a sale area including information such as a geographic location and an administrative area where the real estate contract sale is located may be extracted. At this time, for sale area information, the location information of the intermediary agent user device 300 or the location information of the intermediary agency of the brokerage agent user device 300 may be used.

The intermediary agent information extraction unit 140 may extract the intermediary agent region information from at least one intermediary agent information stored in advance in the intermediary agent information storage unit of the client server 100. Gathering information about real estate contracts for a specific area through an intermediary agent in a geographically adjacent area can be a means to increase the reliability of information about false or abnormal property. Therefore, the intermediary agent region information may include information such as an administrative area in which the intermediary agent is located.

The intermediary agent matching unit 150 may generate one or more intermediary agent matching information that matches the sale area information. The intermediary agent matching unit 150 may determine whether the match is based on a case where the distance between the location of the intermediary agency office according to the intermediary agent area information and the location of the property according to the local area information is within a predetermined range. .

In this case, the predetermined range may be an arbitrary range input through the input unit of the client server 100 or a range preset in the client server 100. For example, at least 10 matching information may be generated in order to obtain a highly reliable verification result for a specific transaction product. The location information of the brokerage agency may be a physical distance between the property and the agency, but is not limited thereto, and may mean proximity to the location information for designating a minimum agency agent for participating in the evaluation of the property.

The evaluation information request unit 160 may transmit the evaluation request information for the real estate contract sale to the intermediary agent user device 300 corresponding to the intermediary agent matching information through the transceiver 110. The evaluation information on the real estate contract sale may include a qualitative evaluation result on whether the price of the real estate contract sale is appropriate or not, and whether the convenience facilities are well equipped in the vicinity.

For example, information on real estate contracts, such as trading conditions (transaction terms such as sales, monthly rent, and charter), area, price, and whether or not there is a loan, direction, corresponding floor / total floor, number of waterproof / bathrooms, number of households, year of tenancy, It can be information that introduces the charter rate, parking space, entrance structure, number of parking per household, date of completion, number of households, construction company, occupancy date, heating method, repair or other real estate contracts. However, the evaluation information is not limited to this, and may include elements recognized as suitable for use in evaluating real estate properties. In addition, the evaluation items that may be included in the evaluation request information may be processed and provided in a preset manner or information on the real estate contract sale received from the transaction request user device 200 may be used as it is.

Next, the intermediary agent evaluation unit 170 may be provided to generate the intermediary agency evaluation information in a preset manner when the transmission / reception unit 110 receives the real estate property evaluation information corresponding to the evaluation request information. At this time, the brokerage agent evaluation information may be used for the purpose of assigning a ranking for compensation for evaluation. For example, since there is a need to quickly generate evaluation information on real estate contracts in order to activate a transaction, the brokerage agent evaluation information is provided by the intermediary agent user device 300 recognized as having transmitted real estate property evaluation information within a predetermined time. It may be provided to be created only by the intermediary agent.

On the other hand, the brokerage agent can settle and receive certain compensation costs as compensation for completing the evaluation information. The compensation cost settlement unit 180 generates compensation cost information by using the agency agent evaluation information according to a preset method, and transmits the compensation cost information settled through the transmission / reception unit 110 to the agency agency user device 300. It may be provided. At this time, the compensation cost information may be generated by using the cost information included in the cost payment information received from the transaction request user device 200.

The cost payment information may be information processed by the reward bank server 400 for processing the compensation cost payment information. The user of the transaction request user device 200 may purchase payment information in the form of a point or token required for payment through the reward bank server 400. The compensation cost information transmitted to the intermediary proxy user device 300 may also be provided as compensation information in the form of points or tokens. Meanwhile, the point or token may be provided in the form of a cryptocurrency, for example.

For example, when cryptocurrency is used for the value exchange means included in the cost payment information, the compensation cost is settled in the order of promptly sending the real estate property evaluation information and provided in the form of a cryptocurrency, or settled in cash for brokerage. It can be transmitted to user equipment.

Comprehensive evaluation information generation unit 190 generates comprehensive evaluation information on real estate contract sale when receiving real estate property evaluation information through the transmission / reception unit 110, and the comprehensive evaluation information is stored in the comprehensive evaluation information storage unit 210. It may be provided.

Meanwhile, the comprehensive evaluation information management unit 200 may be provided to upload the comprehensive evaluation information to the public transaction book through the transmission / reception unit 110. At this time, the comprehensive evaluation information management unit 200 is provided to check whether the transaction has been completed by creating a transaction block in the public transaction book. For example, when a transaction is completed and a transaction block is generated in the public transaction book, transaction completion information may be generated to notify that the transaction has ended, and the comprehensive evaluation information storage unit 210 may remove the comprehensive evaluation information.

The comprehensive evaluation information is not uploaded to the public transaction book, but only to the public transaction book if it meets certain criteria. Through this, it is possible to eradicate false property in advance. In addition, since data for subsequent transactions is prepared and stored in the public transaction book, the client server 100 side can reduce the cost for maintaining and maintaining a large-scale storage space.

2 and 3, in a method of generating information for registering a real estate transaction sale in a transaction book to which a blockchain technology is applied, in order to verify whether a real estate transaction sale satisfies a predetermined criterion according to a preset method , The transmitting and receiving unit 110 of the client server 100 receives real estate contract sale information from the transaction requesting user device 200 (S110). At this time, the real estate contract sale information may include information on the real estate rental property.

Next, the billing cost settlement unit 120 of the client server 100 transmits the cost request information for providing the upload service to the transaction requesting user device 200 through the transceiver 110 (S120). In order to upload the real estate contract sale information to the public transaction book, a procedure for evaluating the reliability of the information on the sale is performed, and thus, a predetermined fee is charged for the reliability evaluation procedure. At this time, for a predetermined cost, various value exchange means such as cash and cryptocurrency can be used.

Next, when receiving the payment payment information corresponding to the billing information through the transmitting and receiving unit 110, the evaluation property information extraction unit 130 of the client server 100 to extract the property area information from the real estate contract sale information It becomes (S130). For example, information on an administrative area may be used as information on an area for sale, and may be prepared to match an intermediary agent for participating in the property evaluation.

The intermediary agent area information may be information on the administrative area where the agency agent's office is located. In the case of real estate sale held by an intermediary agent and relaying a transaction, there is generally no regional restriction, so it is desirable to allow only the local intermediary agent to evaluate the reliability of real estate contract sale information. Therefore, the intermediary agent information extraction unit 140 of the client server 100 extracts the intermediary agent area information from at least one intermediary agent information previously stored in the intermediary agent information storage unit of the client server 100 (S140). In order to request evaluation information from a brokerage agent that matches the contract sale, the brokerage agent matching unit 150 of the client server 100 generates at least one brokerage agent matching information matching the sale area information (S150).

In this case, the intermediary agent matching unit 150 determines whether the match is based on the case where the distance between the location of the intermediary agency office according to the intermediary agent area information and the location of the property according to the local area information is within a predetermined range, or , It may be provided to determine whether or not the matching is based on a case that is within an arbitrary range input through the input unit of the client server 100.

The evaluation information request unit 160 of the client server 100 transmits the evaluation request information for the real estate contract sale to the intermediary agent user device 300 corresponding to the intermediary agent matching information through the transceiver 110 (S160) ), Through which the evaluation of real estate contracts is made. The evaluation request information on the real estate contract sale is transmitted to devices such as smartphones and tablet computers owned by the intermediary agent, and can be provided together with a push alarm to quickly participate in the evaluation.

The brokerage agent evaluates the real estate contract for sale and sends it to the client server. The intermediary agent evaluation information may be generated only by the intermediary agent of the intermediary agent user device 300 recognized as having transmitted real estate property evaluation information within a predetermined time. Through this, it is possible to induce prompt evaluation information to be sent. When the transmission / reception unit 110 receives the property sale evaluation information corresponding to the evaluation request information, the agency representative evaluation unit 170 of the client server 100 generates the agency representative evaluation information in a preset manner (S170). . Points are given to the intermediary agents who have quickly transmitted the evaluation information, and then used for calculating compensation costs.

Compensation cost information may be generated using cost information included in the cost payment information. Specifically, the compensation cost settlement unit 180 of the client server 100 generates compensation cost information by using the agency representative evaluation information according to a preset method, and mediates the compensation cost information settled through the transmission / reception unit 110. It is transmitted to the proxy user device 300 (S180). In other words, since the compensation cost information is generated using the cost payment information, an objective evaluation of the goods is made by providing the compensation for the broker and electronic real estate transactions can be made.

It is possible to ensure that all real estate property evaluations made by brokers are registered in the public transaction book of the blockchain system 500. However, more preferably, when the transmitting and receiving unit 110 receives the real estate sale evaluation information so as to more effectively prevent the false sale, the comprehensive evaluation information generation unit 190 of the client server 100 generates the comprehensive evaluation information and , It can be made to upload only for real estate contracts that satisfy predetermined criteria.

The comprehensive evaluation information management unit 200 of the client server 100 uploads the comprehensive evaluation information to the public transaction book through the transmission / reception unit 110. The uploaded information is interlocked with the public transaction ledger and is stored in the comprehensive evaluation information storage unit 210 of the client server 100 to be provided to the lessee about the real estate.

In the specification and drawings, preferred embodiments of the present invention have been disclosed, and although specific terms are used, they are merely used in a general sense to easily describe the technical contents of the present invention and to understand the present invention. It is not intended to limit the scope. It is apparent to those skilled in the art to which the present invention pertains that other modifications based on the technical spirit of the present invention can be implemented in addition to the embodiments disclosed herein.
