Description

Method for providing consumption information sharing service of verified real buyers based on blockchain {METHOD FOR PROVIDING BLOCK-CHAIN BASED VERIFIED CUSTOMER REVIEW SHARING SERVICE}

The present invention relates to a method for providing a consumption information sharing service of a verified real purchaser based on a blockchain, and provides a method for collecting and sharing consumption information from a real purchaser verified by a blockchain.

In the case of Internet shopping, consumers are not directly looking at the real thing about the product, but the purchase is made by relying entirely on the information, so the anxiety about purchasing the product they feel is relatively high, and in order to resolve the anxiety, the consumer searches for information on product evaluation In order to reduce the effort of users, online review provided by people with experience in purchasing is used. Recently, even when purchasing in an offline store, a tendency to minimize the probability of a purchase failure by searching for the review in advance is large. This online review is highly reliable because it provides many people's opinions for a short time and evaluates the product from the same consumer's point of view, not from a commercial purpose company.

At this time, a method for verifying the product review was developed as the product review was marketed. In this regard, in the prior art, Korean Patent Publication No. 2012-0104714 (published on September 24, 2012), product information and product of product evaluators Register the evaluation information, and when the product is purchased with reference to the registered product information and product evaluation information, provide the evaluation UI for evaluating the product evaluator, and register the evaluation information of the product evaluator evaluated by the buyer through the evaluation UI in the database. By doing so, a product evaluator who directly provides product evaluation information by a buyer evaluates a product evaluator, so that a manufacturer cannot pretend to act as a deceptive consumer, such as manipulating a customer by posting a purchase review.

However, even in the case of evaluation, in the case of inequality in which the numerical advantage is relatively relative to the individual consumer, such as the manufacturer or the seller, the evaluation interface is still used by the seller or manufacturer to pretend to be the customer and upload the purchase review to impersonate the fact to the customer. Advertisers can provide product reviews, and customers who trust them make purchase decisions by relying on external clues such as others' judgments, so the deception of customers still exists and the logic of the market is often distorted.

In one embodiment of the present invention, when a purchase event occurs, payment information, usage information, and personalization information are identified, and transaction information is verified at each node in the blockchain to confirm the actual purchaser and to register consumption information with the actual purchaser The right to evaluate or evaluate is granted by issuing the registration coin and the evaluation coin, and when consumption information is registered or evaluated, the issued registration coin and the evaluation coin are converted into real coins with real value, enabling transactions, and registered It is possible to provide a method for providing a service for sharing consumption information of a verified real purchaser based on a blockchain, so that even when consumption information is shared, a validity period is set to maintain the latest of registered consumption information and evaluated consumption information. However, the technical problem to be achieved by the present embodiment is not limited to the technical problem as described above, and other technical problems may exist.

As a technical means for achieving the above-described technical problem, an embodiment of the present invention is a method for providing a consumption information sharing service executed in a server for providing consumption information sharing service, when a purchase event occurs due to payment of goods from a user terminal , Collecting transaction identification information including payment information, usage information, and personalization information; Issuing a registration coin or an evaluation coin to grant the authority to register or evaluate consumption information with an account of the user terminal when the transaction unique identification information is verified in a blockchain in which the user terminal is a node; When registering or evaluating the consumption information at the user terminal, converting the registration coin or the evaluation coin into a real coin to which a predetermined value is respectively assigned; And mapping and storing and sharing the registered coin and the registered consumption information, the evaluation coin and the evaluated consumption information, and including a new consumer (a customer with a purchase intention) in the consumption information sharing service providing server. When a purchase history request containing one of a specific product, usage, seller, or product price is received from the existing purchaser, the purchase history information of the existing purchaser meeting the received purchase history request is verified based on the blockchain registered in the management unit Extracting consumption information of each product, by use, by seller, by amount, and providing the terminal to a new consumer (a customer with a purchase intention); And a step of establishing and providing a personal chat channel to enable online chatting between new consumers and existing buyers through a blockchain-based verified real buyer's consumption information sharing service application, program, app page, and web page. When registering or evaluating the consumption information at the user terminal, the step of converting the registration coin or the evaluation coin into real coins to which a predetermined value is respectively assigned is when the consumption information is not registered or evaluated at the user terminal, the And converting the consumption information into a real coin to which a preset value is assigned corresponding to a reward for a resource provided to verify at least one event occurring in a blockchain included as a node as a user terminal, and registering the consumption information. , Evaluation, the value of the real coin corresponding to each reward for resources is characterized by the same or different.

According to any one of the above-described problem solving means of the present invention, by sharing the correct consumption information by verified real buyers, so that transparent and authentic information can be generated spontaneously, and based on the blockchain with participants as each node This guarantees integrity by verifying the events or transactions that occur, and by keeping the shared information up-to-date, it is possible to prevent consumption information from being distorted due to indiscriminate information caused by unspecified unilateral participation. As a tool of advertising internet marketing, it can recover the trust of the lost consumer.

In addition, according to any one of the above-described problem solving means of the present invention, a new consumer can be provided with evaluation and opinions from an existing purchaser based on the purchase history information of the existing purchaser, the product to be consumed, the seller, and the amount Based on this, rational consumption can be planned.

FIG. 2 is a block diagram for explaining a server for providing consumption information sharing service included in the system of FIG. 1, and FIG. 3 is a block chain-based verified consumer purchaser sharing service implementation according to an embodiment of the present invention It is a diagram for explaining one embodiment.

Referring to FIG. 2, the consumption information sharing service providing server 300 may include a collection unit 310, a publishing unit 320, a switching unit 330, a sharing unit 340, and a management unit 350. .

Blockchain-based verification by the user terminal 100, and at least one participant terminal 400 by the server 300 for providing consumption information sharing service according to an embodiment of the present invention or another server (not shown) operating in cooperation When a real purchaser's consumption information sharing service application, program, app page, web page, etc. is transmitted, the user terminal 100 and at least one participant terminal 400 share blockchain-based verified real purchaser's consumption information You can install or open service applications, programs, app pages, web pages, and more. In addition, the service program may be driven in the user terminal 100 and at least one participant terminal 400 by using a script executed in a web browser. Here, the web browser is a program that enables the use of the world wide web (WWW) service, and refers to a program that receives and displays hypertext described in a hypertext mark-up language (HTML), for example, Netscape. , Explorer, Chrome, and the like. Further, the application means an application on the terminal, and includes, for example, an app that is executed on a mobile terminal (smartphone).

Referring to FIG. 2, the collection unit 310 may collect transaction identification information including payment information, usage information, and personalized information when a purchase event occurs according to payment of an item from the user terminal 100. have. At this time, the purchase event may be information collected from an account for transactions in the blockchain in the user terminal 100 or payment means linked to the account.

Here, since a person cannot exist in two places at the same time, and there cannot be two transactions occurring at the same time at the same place of use, it acts as a unique code that proves the transaction when using payment information, place-of-use information, and personalized information. can do. Accordingly, it can serve as a basis for granting authority to write or evaluate consumption information such as reviews or reviews of consumption based on a unique transaction record. At this time, the collection unit 310 may be collected when the user terminal 100 uses a payment application, program, page, etc., which is a personalized wallet of the blockchain, or when using a separate payment method connected to the personalized wallet. It is obvious that it is not excluded to collect it when not in use.

The issuing unit 320 registers to grant authority to register or evaluate consumption information with the account of the user terminal 100 when the transaction unique identification information is verified in the blockchain in which the user terminal 100 is included as a node. Coins or evaluation coins can be issued. At this time, the registered coin and the evaluation coin are not cryptocurrencies with embedded values that can be used in the actual transaction, but rather a coin in the previous stage where the registered coin and the evaluation coin can be converted into real coins with embedded values that can be used in the actual transaction. It is defined as the right to register or evaluate consumption information. However, it does not exclude that the registered coin and the valuation coin are cryptocurrency with a value that can be used in actual transactions.

When the consumption information is registered or evaluated in the user terminal 100, the switching unit 330 may convert the registered coin or the evaluation coin into a real coin to which a predetermined value is respectively assigned. That is, in the case where the user terminal 100 purchases the A product or purchases and uses the A service, the consumption information sharing service providing server 300 as a content including text, images, and videos of his thoughts or written experiences about A 300 ), The conversion unit 330 converts the registration coin or evaluation coin issued to the user terminal 100 into the real coin, which is a real cryptocurrency, so that the transaction is possible in the user terminal 100. For example, it is assumed that the A product is 10,000 won, the A product is purchased from the user terminal 100, and the registered coin and the evaluation coin have 60% and 40%, respectively, of 0.6% and 0.4% of the payment amount. At this time, when the user terminal 100 writes a review for product A, the registered coin is converted into a real coin (60 won) that can be traded for 60 won. In addition, when the user terminal 100 evaluates the A product or evaluates other people's consumption information (such as product reviews), the evaluation coin is converted into a real transactionable coin of 40 won (40 won).

In addition, when the consumption information is registered or evaluated in the user terminal 100 in the switching unit 330, when the registration coin or the evaluation coin is switched to a real coin to which a predetermined value is respectively assigned, the consumption in the user terminal 100 When the information is not registered or evaluated, the user terminal 100 is a real coin to which a predetermined value corresponding to a reward for a resource provided to verify at least one event occurring in a blockchain included as a node is assigned. You can switch. At this time, the value of real coins corresponding to registration, evaluation, and compensation for resources may be the same or different.

At this time, if the user terminal 100 does not have a registration coin or an evaluation coin according to a purchase event, or a registration coin or an evaluation coin due to a purchase event other than a purchase event, the consumption information according to the purchase event is registered or Cannot be evaluated For example, the user terminal 100 is not authorized to register or evaluate consumption information for the B product when the A product is purchased. To this end, the transaction record may further include information on what products or services were purchased.

The sharing unit 340 may map the registered coin and the registered consumption information, the evaluation coin and the evaluated consumption information, and store and share it. Through this, bloggers who are not real buyers do not infringe on the sharing of fair information by sponsoring and biased information from sellers for marketing, or by dealing with comments by sellers' officials, employees, etc. who are not real buyers. That is, the fact that the registration coin or the evaluation coin has been granted proves that it was purchased directly, so it can be authenticated as a real purchaser by mapping, storing and sharing it.

The management unit 350 maps, stores and shares the registered coin and the registered consumption information, the evaluation coin and the evaluated consumption information in the sharing unit 340, and then updates the consumption information within a preset validity period of the registered consumption information. If exists, the registered consumption information can be compared with the updated consumption information. Then, the management unit 350 newly registers the updated consumption information when there is a content change that includes the addition and deletion of the comparison result content, and when there is no content change that includes the addition and deletion of the comparison result content The validity period of the updated consumption information can be extended. At this time, if the preset expiration date of the registered consumption information has elapsed, the registered consumption information may be deleted or deactivated. Accordingly, the currentity of consumption information can be maintained, and the person who has shared the consumption information can also accurately predict the product or service that is actually being sold by sharing the information closest to the present.

The management unit 350 maps, stores and shares the registered coin and the registered consumption information, the evaluation coin and the evaluated consumption information in the sharing unit 340, and then displays the latest score of the registered consumption information and the evaluated consumption information. The ranking of the latestness of consumption information evaluated as a result of summing the latest scores can be calculated. At this time, the latest score of the registered consumption information is based on a score deducted corresponding to the ratio of the number of days elapsed since registration for the preset validity period, and the latest score of the evaluated consumption information is evaluated after the preset validity period. It may be based on a score that is subtracted corresponding to the percentage of days elapsed.

At this time, when determining the ranking of the product information, superiority may be considered in addition to the latest. In other words, as described above, the deduction system is operated within the expiration date as described above, and excellence can be referred to as the use of evaluation coins.For example, evaluation A has passed 1 month since it was registered, and there are 2 others' evaluation information. , If the first evaluation was 4 days with 10 stars and the second evaluation was 3 stars with 20 days, the latest registration

Up-to-date registration: 100 points × (3 months-1 month) ÷ 3 months (* 1 month is the number of elapsed months, 3 months is the validity period)

Is calculated as, and excellence is

1st evaluation score: 1 point × [5-(5-4)] × (30 days-10 days) ÷ 30 days (* 5 is MAX for evaluation, 4 is evaluation number, 30 days for evaluation validity, 10 days elapsed Days)

2nd evaluation score: 1 point × [5-(5-3)] × (30 days-20 days) ÷ 30 days (* 5 is MAX by evaluation, 3 is evaluation number, 30 days is evaluation validity period, 20 days have elapsed Days)

Can be calculated as That is, additional compensation for the ranking is given to the product information registrant and the person who evaluated it, and this is a process that allows users to select and manage reliable consumption information by themselves.

On the other hand, at least one data including collection of transaction-specific identification information, issuance of a registration coin or an evaluation coin, and conversion of a real coin can be verified in at least one node included in the blockchain. Of course, verification may occur at various stages other than the above-described process. In addition, transactions between at least one node included in the blockchain may be performed by a smart contract. At this time, the blockchain of the present invention can be largely composed of four basic technologies such as peer-to-peer (P2P) network, encryption, distributed ledger, and distributed agreement. Each of the technologies takes a complementary relationship to decentralization, which is the value of the blockchain, and maintains the integrity of the data, and forms the basis of the mechanism of the blockchain operation. On the other hand, smart contract, an application technology in a blockchain environment, is a technology that provides integrity and reliability for program execution codes and their results, which will be described in detail below.

First of all, P2P network is based on the connection and communication between participants in the blockchain, and P2P network is a network composed of participants of the same layer that deviated from the existing client-server method, largely structured P2P (structured P2P) and unstructured P2P (non Structural P2P). In particular, unstructured P2P can be divided into a distributed P2P network based on a centralized method in which networks between participants are centered around servers and a flooding algorithm of data. For decentralized distributed networks, flooding-based unstructured P2P networks can be used, and communication of P2P networks is generally done through UDP, but blockchain uses TCP / IP. Therefore, the participants of the blockchain maintain the IP of the participants who are physically closest to them, and can use them to exchange messages and data.

The encryption technology includes, but is not limited to, a Merkle Tree for verifying the integrity of data, a public key-based digital signature technique for preventing repudiation of transactions, and the like. Merkle tree is a type of hash tree, in which all non-leaf nodes have names consisting of hashes of child nodes, that is, leaf nodes point to data such as files or specific values, and the upper node is a tree composed of hash of this leaf node. The root node of the Merkle tree constructed in this way is composed of hash values of the data of all leaf nodes constituting the tree, and the user can verify forgery and alteration of data only by verifying the hash of the root node. In addition, the public key-based digital signature method is an encryption technology that enables secure communication between participants who have not previously shared a secret key, and is widely used in fields such as personal authentication. In the public key infrastructure, there are two key pairs, a public key and a secret key, and the public key is known to all participants, but the corresponding secret key is maintained only by the corresponding owner. Blockchain is used to verify the validity of transactions.

Third, the distributed ledger is a record storage of information that is replicated, shared, and synchronized by agreement among the participants. Particularly, in order for the distributed ledger to be applied on a P2P network, participants' agreement on the records of the distributed ledger is required. Blockchain maintains its characteristics. In the blockchain, the distributed ledger records all transactions and information that occur through the verification process of participants, and all participants maintain the same information. When verifying a transaction or information, first check the connectivity with the information already recorded in the distributed ledger maintained by each participant, and after agreement between the participants, only the legitimate transaction or information is stored in the distributed ledger of the blockchain, When storing transactions or information, they are accumulated for a period of time and stored in units called blocks, and stored in a distributed ledger in a state where connectivity between the blocks is given. This distributed ledger serves as the basis for guaranteeing the data integrity provided by the blockchain, and since all users participating in the blockchain maintain the same distributed ledger, an attacker from the outside attempts to falsify or falsify specific data. In order to do so, more than half of the distributed ledgers maintained by the participants must be attacked, which requires high cost and computing resources, which can reduce the risk of forgery or double transactions.

Fourth, distributed consensus is a protocol that derives consent for specific data values between processes or agents to achieve overall system reliability when there are defective processes in distributed computing and multi-agent systems. The protocol has the following characteristics. First of all, if validity, i.e., all correct processes suggested the same data, then all processes make a decision (valid, invalid) on the proposed data, and then integrity, i.e., all correct processes If data is adopted, the data is data proposed by other processes, and agreement, that is, all correct processes must agree on some data, termination, that is, all correct processes are on certain data The decision is to make it. In the blockchain, the decentralized consensus protocol is designed as above, and consensus among participants is derived for the transaction or information generated through this, and only the appropriate transaction or information is maintained in the blockchain through the agreement, and the type is Proof- Consensus algorithms such as Tendermint based on of-work or Proof-ofstake, Delegated Proof-of-Stake, and PBFT (Practical Byzantine Fault Tolerance) may be used, but are not limited thereto.

Finally, smart contracts are defined as computer transaction protocols that enforce contract terms, and minimize brokers for trust in transactions, while meeting contract terms and minimizing malicious exceptions, automating between trading parties without intermediaries or central agencies. Enables direct transaction, and maintains the conditions and results in a distributed ledger to ensure the reliability and integrity of transaction information. That is, the user programs a protocol smart contract containing the desired conditions and stores it in the blockchain, and when a specific condition is satisfied, the smart contract is verified and executed by other blockchain participants. The execution results are stored on the blockchain again, and the integrity and reliability of information on the transaction results are also guaranteed.

Meanwhile, referring to FIG. 2, the server 300 for providing consumption information sharing service according to an embodiment of the present invention manages purchase history information of an existing buyer that satisfies a purchase history request from a new consumer (a customer with a purchase intention) ( It may further include a consumer matching unit 360 extracted from 350) and provided to a terminal of a new consumer, and establishing and connecting a chat channel between an existing buyer and a new consumer.

Therefore, the new consumer has the advantage of being able to receive an evaluation from the existing purchaser based on the purchase history information of the existing purchaser, the product to be consumed, the place of use, the seller, and the amount, and to plan a reasonable consumption based on the evaluation.

Hereinafter, an operation process according to the configuration of the above-described server for providing consumption information sharing service of FIG. 2 will be described in detail with reference to FIG. 3 as an example. However, the embodiment is only one of various embodiments of the present invention, it will be apparent that it is not limited thereto.

Referring to FIG. 3, it is assumed that (a) the user terminal 100 has ordered the ice americano at the A shop. At this time, payment information and usage information are generated according to a transaction generated through POS of the shop A, and personalized information is extracted from the wallet of the user terminal 100 and transmitted to the consumption information sharing service providing server 300 .

Then, (b) the consumption information sharing service providing server 300 issues and transmits a registration coin and an evaluation coin to the user terminal 100 to share the consumption information for purchasing the ice americano. At this time, (c) In the case where the user terminal 100 registers a review or evaluation of the ice americano purchased at the coffee shop A, the registered coin held in the user terminal 100 is converted into a real coin, so that a transaction is possible. Converted to currency. Similarly, in the case where (d) the user terminal 100 evaluates consumption information (such as reviews) of another person's ice americano purchased at the coffee shop A, the evaluation coin possessed by the user terminal 100 is converted to the real coin. By doing so, it is converted into a virtual currency that can be traded. On the other hand, (e) even if the user terminal 100 does not register or evaluate consumption information, at least one participant terminal 100 generates a transaction or receives a real coin for a plurality of transactions. If computing resources or network resources are provided as a node in the blockchain by performing operations to ensure integrity, this also acts as a cause of converting the registration coin and evaluation coin into real coins.

In this way, if the consumption information has been uploaded, shared, and evaluated, (f) the consumption information sharing service providing server 300 determines whether consumption information has been updated to maintain the latest since verification of the consumption information has been completed. Consumption information that has passed the expiration date is discarded or deactivated, and if an update (addition, deletion, etc.) has not occurred, simply re-register it to extend the preset expiration date. In addition, the consumption information sharing service providing server 300 determines whether the evaluation is recent or not, and the more the evaluation date has elapsed from the present, the more the registration date has elapsed from the present, the score is deducted, that is, through the deduction according to the elapsed date. It can lead to continuous new registration and evaluation.

Hereinafter, an example of a process in which data is transmitted and received between each of the components will be described with reference to FIG. 4, but the present application is not limited to such an embodiment, and is illustrated in FIG. 4 according to various embodiments described above. It is apparent to those skilled in the art that the process of transmitting and receiving data can be changed.

4, the consumption information sharing service providing server 300, when a purchase event occurs in the user terminal 100 (S4100), collects the transaction identification information (S4200), through each node in the blockchain The transaction is verified (S4300), and the registration coin and the evaluation coin are issued to the user terminal 100 that generated the transaction (S4400, S4500). Then, the consumption information sharing service providing server 300 checks whether the consumption information is registered or evaluated in the user terminal 100 (S4700), and if registered or evaluated, converts the value according to registration or evaluation (S4710) ), So that the registered coin or the evaluation coin is converted to the real coin (S4730), and if consumption information is neither registered nor evaluated, the value is converted according to the provision of resources to provide compensation for providing resources as nodes in the blockchain. By doing (S4720), the registered coin and the evaluation coin are converted into real coins (S4730, S4740).

Meanwhile, the consumption information sharing service providing server 300 shares the registered consumption information or the evaluated consumption information (S4800), and maintains the sharing state when the expiration date of the consumption information has not passed (S4810, S4830) , If it has elapsed, the registered consumption information is deleted or deactivated (S4820). And, if the consumption information is updated within the validity period (S4840), if the content is actually edited (added, deleted, etc.), the consumption information is newly registered (S4870), otherwise, the content is not changed again. Since it is registered (simple registration) (S4850), the validity period is extended (S4860). In addition, the consumption information sharing service providing server 300 induces continuous new registration and evaluation by summing the latest score on the registration date and the latest score on the evaluation date when calculating the ranking score to secure the latest in the evaluation of consumption information. It can be (S4900).
