Description

Encounter system using blockchain technology {MEETING SYSTEM USING BLOCK CHAIN TECHNOLOGY}

The present invention relates to an encounter system using a blockchain technology capable of requesting an encounter between members without any intermediate introduction and sharing contact information with each other by a smart contract method of the blockchain.

In Block Chain technology, Block contains the transaction details confirmed for a certain period of time. Blocks with transactions are formed online. It is the user who determines the transaction details. This block is sent to all participants in the network. Participants confirm the feasibility of the transaction. Only the approved block is connected to the existing blockchain, and the transfer is made. The feature of the blockchain is that it is not a credit-based system, and it is possible to exchange values among trading parties without constructing a network with a system and guaranteeing transactions by third parties.

Smart contracts refer to the execution and execution of various types of contracts such as financial transactions, real estate contracts, and notarization based on blockchain. Also called Blockchain 2.0.

It forked Bitcoin to create a new cryptocurrency called Ethereum and implemented a smart contract function. With this feature, developers can code terms and conditions directly, so in principle, any kind of contract imaginable by humans can be implemented using the Ethereum platform.

Looking at the conventional meeting or blind date arrangement system, in the meeting service providing company, if the manager arranges meetings between people who meet similar conditions based on the member's information, or if they apply for the meeting by viewing the member's information on the homepage It is done by accepting or rejecting it.

However, according to the conventional structure, since it is easy for a third party to modify the contents of the evaluation of the other party after the meeting, the reliability of the information is poor and the personal information of each member is stored on the server. There is a high concern, and there is a problem that their personal information is exposed to third parties and managers of service companies too easily.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2, the encounter system using the blockchain technology according to the present invention is composed of an encounter management server 100 and an electronic wallet 200.

The contact management server 100 includes a member list DB 110, a member information providing unit 120, a member evaluation unit 130, a member level adjustment unit 140, and an evaluation verification unit 150.

The electronic wallet 200 includes a private key / public key DB 210, a personal information DB 220, a smart contract processing unit 230, and a distributed ledger 240.

First, install the electronic wallet 200 and access the encounter management server 100 to proceed with membership registration (S210) .

The contact management server 100 manages the member information subscribed to the blockchain system through the electronic wallet 200 and accesses the server 100 to the member list DB 110 of the server 100 to the requesting member. Provide a list of registered members.

The electronic wallet 200 registers and manages a private key (Private-Key) and a public key (Public-Key) in the private key / public key DB 210 (S220) . In the process of creating the electronic wallet 200, the public key generated through the private key is stored in the private key / public key DB 210, and when the cryptocurrency is traded with the counterpart, the corresponding key is stored. It is to use.

The electronic wallet 200 enters a plurality of personal information to be provided to the counterpart for the encounter in the personal information DB 220 to record its personal information in a blockchain-based system (S220) . Personal information includes name, age, gender, job, job name, and work address.

The smart contract processing unit 230 of the electronic wallet 200 provides its personal information to the counterpart automatically selected from the list provided by the contact management server 100 or the counterpart selected by the member in the form of smart contracts of the blockchain. Provide the first request to meet (S230) , and when the other party approves it (S240) , receives the other party's personal information from the other's electronic wallet 200, and at the same time shares each other's contact information (S250) . After sharing the contact information, you will meet each other (S260) .

The form of the electronic wallet 200 may be any form such as a software wallet or a hardware wallet.

Smart contracts are digital contract methods that code contract terms based on blockchain technology and fulfill the contract if the terms are met. It is a kind of automated contract system.

The member information providing unit 120 of the contact management server 100 is a member who provides information included in the type of information disclosure corresponding to the information providing condition of the member requesting the inquiry or information included in the information disclosure type of the member requesting the inquiry. Search and provide the list.

For example, when member A requests inquiry, if the type of information disclosure corresponding to the condition of providing member information is three, name, age, and job, the meeting management server 100 is the same as the type of information disclosure of member A. Search and provide a list of members who provide three types of name, age, and job as conditions for providing information.

It also searches and provides a list of members who provide one or two of their names, ages, and jobs as conditions for providing information. That is, any condition included in the information provision conditions of member A can be searched and provided. Of course, we do not provide a list of members who provide their name, age, and job name and work address as conditions for providing information.

If, member B provides three types of name, age, and job as conditions for providing information, member C provides two names and age as terms of information, and member D provides name, age, job, and name of job When provided as a provision condition, when member A requests inquiry, the meeting management server 100 searches for members B and C and provides them to member A, and does not provide information about member D.

Specifically, the contact management server 100 provides a list of members who provide information included in the type of information disclosure of the member who requested the inquiry or the same type of information disclosure of the member who requested the inquiry, but the list provided is minimal. Provide only basic information.

That is, in addition to the minimum basic information provided as a list, only the category in which the information disclosure type set as the information provision condition will provide any information, and the contents included in the category are not disclosed.

In the above example, when searching B members and C members for the inquiry request of member A and providing them as a list, the surname information of members B and C may be provided, and the name may be hidden. And only minimal basic information, including age, can be provided.

In addition to this minimum basic information, member B can provide that they will provide name, age, and work information as conditions for providing information, and member C can provide that they will provide name and age as conditions for providing information.

After all, if only the minimum basic information is viewed and the other party accepts it by requesting a meeting in the smart contract method of the blockchain, then the specific information set by the other party as the conditions for providing information can be known.

The electronic wallet 200 requests an encounter from the list provided, automatically or to the other party selected by the member, by using the smart contracts method of the blockchain, including the kind of information that he or she sets as the information provision condition. If this is approved, the other party's electronic wallet 200 receives the other party's personal information set as the information provision condition, and shares each other's contact information.

If member A selects member B and requests to meet in the form of smart contracts, and member B approves it, the name, age, and work set by member B from the electronic wallet 200 of member B as the information provision condition It receives three pieces of information and shares each other's contact information. Of course, when member A requests to meet by smart contract method, member A's name, age, and work information will be provided to member B.

In addition, each member can access the server 100 and change and set the type of information disclosure corresponding to the information provision condition of the member who requested the inquiry. For example, member A has set the name, age, and job as the conditions for information disclosure. In addition to the name, age, and job, the name of the job and the address of the job can be added to further set the type of information disclosure.

The member evaluation unit 130 of the contact management server 100 inputs what evaluates the content including the correspondence of information posted by the other party and the feelings of favor and attitude toward the other person during the encounter process after the meeting is established between members. Receiving (S270) , propagating it to the network of the blockchain system and adding it to the blockchain distributed ledger 240 stored in the electronic wallet 200 of the members (S280) .

After A members and B members meet, they will access the server 100 to evaluate the feelings and preferences of the other party. At this time, member A can evaluate and input the correspondence of information uploaded by member B and the feeling and preference of the other person. Member B will be evaluated in the same way.

When the evaluation is completed, it is propagated to the network of the blockchain system and added to the blockchain distributed ledger 240 stored in the electronic wallet 200 of the members. Eventually, members will evaluate the other side carefully, and only evaluate and enter the truth.

The membership level adjustment unit 140 of the contact management server 100 lowers the ranking of providing search results for the member and increases the service usage fee by a certain percentage when the evaluated content is negative or the evaluation score is low. If the low score persists for a period of time, it will be withdrawn or constrained.

For members whose information posted on the server is inconsistent or has a bad attitude in meeting, the evaluation may be negative or the evaluation score may be low. These members will be able to lower the ranking when searching for search results and increase the service fee by 3-5%. In addition, if a negative evaluation or low score persists for 3 to 4 months, you may opt-out or stop providing contact services for a certain period of time.

The membership level adjustment unit 140 of the contact management server 100 increases the search result providing rank for the member when the evaluated content is positive or the evaluation score is high, and displays a specific mark or coin corresponding to the reward when providing the search result To the member's e-wallet 200, or a certain percentage of service usage fees can be waived.

If the evaluation contents of the member are positive or the evaluation score is high, the ranking is high when searching for search results, and when providing search results, a specific mark is displayed next to the name to make it stand out, or a given coin is sent to the member's electronic wallet 200 Can provide. Of course, you may be able to exempt 5% of the service fee for 2-3 months.

The evaluation and verification unit 150 of the encounter management server 100 transmits a verification request message for evaluation to the terminals of other members who have evaluated the member when the evaluation for the member exceeds a certain level from the average value for the member. , Blocks stored in the e-wallet 200 of members by receiving a verification response message from other members, determining whether to reflect the evaluation of the member based on the verification response message, and propagating the evaluation reflection result to the network of the blockchain system It is to be added to the chain distributed ledger 240.

For example, if the result of evaluation of member B by member A is outside the average of -6 to +6 points for member B, a verification request message is sent to other members who have evaluated member B, and from other members By receiving the verification response message, based on this, it is determined whether member A reflects the evaluation of member B.

Analyze the verification response message received from other members, and if more than half of the responses are close to the results of evaluation by member A for member B, the results of evaluation by member A for member B are propagated to the network of the blockchain system to distribute the blockchain It will be reflected in the ledger 240.

The member level adjustment unit 140 of the contact management server 100 lowers the ranking of providing search results for members who have not entered the evaluation and reduces the service usage fee if a rating for the other party is not entered after the meeting is established between members. Will increase.

If member A does not enter the evaluation for member B after the meeting between member A and member B, the search result for A member may be lowered and the service fee may be increased by 3-5%.

According to the present invention, in the process of finding the desired partner, the user's own information is recorded in a blockchain-based system as objectively as possible, and based on this, a person who meets the requirements is searched for in the smart contract form of the blockchain. Providing information first, requesting a meeting, and if the other person approves it, contact information of each other can be shared, so that meetings can be made, and there is no need for managers to relay meetings in the middle, and high trust in each other in meetings between members Can form.

The present invention has been described in detail with reference to preferred embodiments, but those skilled in the art to which the present invention pertains can describe the present invention in other specific forms without changing its technical spirit or essential features, as described above. It should be understood that the embodiments are illustrative in all respects and not restrictive.
