Description

Mortgage loan system and method based on vehicle valuation {SECURED LOAN SYSTEM BASED ON APPRAISAL OF VALUE OF VEHICLE AND METHOD THEREOF}

The embodiment relates to a security loan system and method based on vehicle valuation.

P2P lending is a new type of loan that many investors (creditors), not banks or private banks, collect and lend directly to individuals or companies.

P2P loans are all online and can reduce recruitment and labor costs. Investors can earn higher profits than bank interest rates. The market is growing rapidly due to various advantages such as possible.

Most of the current car loans are credit-backed loan products. Except for some high-credit customers, automobiles, especially used car loans, are high interest rate products for medium and low credit customers, and P2P loans can benefit individual consumers at reasonable rates. have

In particular, commercial vehicle loans are only eligible for loans when a dealer (car dealer) contract exists, and loans cannot be made in private transactions that are not related to the dealers. The situation is paying too much money to the lender.

The above causes are loaned through the credit rating based on the sales amount when calculating the loan amount in the financial evaluation of the financial sector, but it is not accepted because the screening criteria for the sales price of vehicles are difficult to recognize.

The evaluation of used car prices is carried out under the Automobile Management Act of the Ministry of Land, Infrastructure and Transport.The buyer of a used car asks the seller to investigate the price of the used car before the contract is concluded. It is a mandatory system to provide a written notice of the details of the survey calculation. At this time, the qualified person for the price survey calculation must be qualified as a vehicle engineer and a diagnostic assessor.

We propose a new method for estimating the authorized price, taking into account the quality of the car, the driving history, the change of use and the current price of the value of the car, and based on this value, P2P loans online for personal transactions. This is possible.

An embodiment of the present invention provides a method and system for preliminarily examining a price estimate of a vehicle by a qualified person when a P2P security loan is made, and determining the loan through an online smart contract according to the result.

Through this, it is possible to solve the problem that the mortgage loan is not serviced in the financial sector, and the middle and low creditors can borrow at reasonable rates, and minimize the risk of investors due to the mortgage loan.

Tasks to be solved by the present invention are not limited to the above-mentioned problems, and other tasks not mentioned above may be clearly understood by those skilled in the art to which the embodiments proposed from the following description belong. will be.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings, and the same or corresponding components will be given the same reference numerals regardless of the reference numerals, and redundant description thereof will be omitted.

1 is an overview of the overall system of the present invention. Here, individuals (loans) apply for collateral loans for vehicles between individuals, and enter into smart contracts with vehicle value assessors and vehicle quality assessors. The contents of this smart contract are automatically executed when the quality evaluation and price estimate for each security vehicle is issued, and the issuance fee is paid through the platform.

The smart contract is encrypted and distributed and managed by blockchain on individual buyers (lenders), individual sellers (vehicle owners), quality evaluators, vehicle value evaluators, and P2P loan platforms, eliminating the risk of security and hacking.

The lender establishes a vehicle valuation (quality assessment, price estimate) and loan conditions (interest rate, period, etc.) and discloses it on the platform. If the investor's participation is low, the loan amount and loan terms can be modified / started.

Individual investors view quality and price estimates for secured vehicles, review loan conditions and decide on investment participation. In order to reduce the loan risk, N investors are required to participate, and the platform provider discloses the policy in advance.

When N investors participate in the investment, the blockchain-based smart contract is renewed, and the investment amount is automatically determined in 1 / N, and when the investment amount is individually transferred, the smart contract is concluded.

Finally, the platform guarantees the payment of the principal to the vehicle seller, the contract partner, and executes the smart contract (transfer of title) between the lender and the vehicle seller, and completes the loan contract after setting up the mortgage in the name of each investor.

 [Glossary]

Vehicle Value Evaluator: Means a vehicle engineer and a diagnostic assessor who are qualified to calculate the automobile price under the Automobile Management Act.

Vehicle Quality Evaluator: A person who possesses the qualification for automobile maintenance and possesses the actual offline maintenance tools and vehicle diagnostic equipment.

Smart Contract: A contract made out of digital instructions that are executed automatically when certain conditions of the contract are met without a separate intermediary. In other words, when a vehicle quality evaluator issues a vehicle quality evaluation report during a smart contract with a lender, the contract is executed to obtain revenue (fee). At this time, digital contract is managed by encrypting with block-chain.

 P2P Loan Platform: relays individual smart contracts with each platform participant, supports safe transactions, and deducts relay fees when each smart contract is executed

2 is a structure of a smart contract concluded between each participant until the loan is completed, the parties of the smart contract may participate in the contract as a terminal equipped with a network and a web browser.

Smart contracts are encrypted with blockchain and distributed and managed on each node and platform. In other words, N smart contracts are required to complete P2P loans, and each contract is distributed and managed in contract participants, contractors, lenders, investors, and platforms. In other words, in order to hack smart contracts, the blockchain is hacked on all participants' nodes, which is known as theoretically impossible.

One smart contract consists of N statements and transactions, and each node retrieves pending transactions, processes the work, sends the proof of work to that node, and completes the entire loan. Updates and broadcasts the smart-chain blockchain to maintain contract integrity.

3 is a procedure in which an individual who wants to receive an initial car security loan makes a smart contract with a seller.

First, smart contracts for sale are signed between car buyers and sellers. At this time, the contractor agrees on the terms and conditions of the general contract of sale and prepares a contract of sale. The seller must register car identification information such as car number and chassis number, and approve it at each node.

The registered information is stored in the block, and the associated smart contract is processed and held until the transaction of the current smart contract becomes a condition to be executed.

Figure 4 is a procedure for proceeding the smart contract for the quality evaluation of the car, the collateral, the borrower is contracted collateral.

In order to calculate the exact value of a vehicle, quality evaluation of the vehicle provided as collateral must be preceded. Sign smart contracts between mechanics, vehicle sellers and buyers certified on P2P platform (inspection equipment, tools, systems, maintenance qualifications, etc.). At this time, the block id of the previous smart contract is connected to form one smart contract to secure the sequentiality of the contract.

According to the contract, the inspection is carried out after the vehicle is received at the workshop of the relevant company. After that, the diagnosis results are uploaded to the platform, and a quality evaluation certificate is issued in the name of the mechanic.

Each node that participates in the smart contract, namely the buyer (loan applicant), seller, and platform, approves the result and pays the mechanic for the credentials.

The block is then suspended until the next procedure.

Figure 5 is a procedure for proceeding a smart contract for the valuation of the vehicle, the collateral, the borrower contracted collateral.

A smart contract is signed to create a value for a collateral vehicle (creating a block id). At this time, it links the quality evaluation block id of the previous block, and the buyer / seller who participates in the smart contract is authorized to view the quality evaluation information.

Based on the quality assessment, the relevant vehicle engineer and diagnostic assessor calculates the vehicle grade and price, uploads the value estimation information to the platform, and issues a value estimate.

The results are approved by the platform, the buyer (the lender), and the seller, update the block, and broadcast to the smart contract connection node and block.

6 is a smart contract procedure related to car security loans.

The platform sets conditions on loan-related returns, loan periods, and principal split payment terms, and calculates and presents investment risk rates on the platform.

The investment risk ratio does not present the risk rate after a normal credit rating, but automatically calculates the value decline rate due to automobile accidents based on the insurer's accident rate information, the borrower's auto insurance, and the depreciation rate by vehicle model.

Depending on the risk of investment, the loan amount is adjusted to a maximum of 80% or less of the estimated price, thereby avoiding any loss due to the depreciation of the security.

As a result, loan conditions, loan amount and investment amount per person are completed and disclosed to investors.

The investor sees the loan conditions and distributes the investment amount to proceed with the smart contract. That is, when the investment amount is 10 million won, the contract is divided into the maximum investment limit of one person per smart contract, and when the recruitment of N persons per one smart contract is completed, the first recruitment of the smart contract is completed.

After the initial recruitment is completed, the investment amount is deposited into the platform virtual account, the investor-specific block is updated, and approval is completed at each contract participant node.

After the loan is transferred to the loan contractor's virtual account, the buyer (seller) approves it, and the platform acts on behalf of the mortgage for the car.

Update the connection block for the final smart contract and notify the completion of the smart contract after broadcasting.

The term '~ part' used in the present embodiment refers to software or a hardware component such as a field-programmable gate array (FPGA) or an ASIC, and '~ part' performs certain roles. However, '~' is not meant to be limited to software or hardware. '~ Portion' may be configured to be in an addressable storage medium or may be configured to play one or more processors. Thus, as an example, '~' means components such as software components, object-oriented software components, class components, and task components, and processes, functions, properties, procedures, and the like. Subroutines, segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables. The functionality provided within the components and the 'parts' may be combined into a smaller number of components and the 'parts' or further separated into additional components and the 'parts'. In addition, the components and '~' may be implemented to play one or more CPUs in the device or secure multimedia card.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
