Description

METHOOD 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 an actual purchaser verified using a blockchain.

In the case of online shopping, consumers are totally dependent on the information instead of directly looking at the real thing about the product, so the anxiety about purchasing the product is relatively higher, and in order to solve the anxiety, consumers search for information on product evaluation. In order to reduce the trouble of using the online reviews provided by people who have experience in the purchase, in recent years, even when purchasing in the offline stores tend to minimize the probability of purchase failure by searching the reviews in advance. These online reviews have high credibility because they provide a large number of people's opinions in a short period of time and evaluate the product from the same consumer's point of view, not from a commercial company.

At this time, a method for verifying a product review was developed as the product review was marketed. In this regard, Korean Patent Application Publication No. 2012-0104714 (published on September 24, 2012), which is a prior art, includes product information and a product evaluator's product. If the product is purchased by referring to the registered product information and product evaluation information, the evaluation information is provided for the evaluation of the product evaluator, and the evaluation information of the product evaluator evaluated by the buyer is registered in the database through the evaluation UI. By doing so, the purchaser evaluates the product evaluator who directly provided the product evaluation information, and thus, the manufacturer can disguise the customer such as operating the customer by putting up a customer's review.

However, even in the case of evaluation, in an uneven situation in which a numerical advantage is relatively higher than an individual consumer such as a manufacturer or a seller, the evaluation interface is still used by the seller or the manufacturer to impersonate the customer by uploading a review. It is possible to provide product reviews, which are advertisements, and customers who trust them make purchase decisions based on external clues such as the judgment of others. Therefore, deception of customers still exists and the logic of the market is often distorted.

According to an embodiment of the present invention, when a purchase event occurs, payment information, usage information, and personalization information are identified, the transaction information is verified at each node in the blockchain, and the actual purchaser is determined, and the consumption information is registered with the actual purchaser. Or issuance of a registration coin and a valuation coin, and when consumption information is registered or evaluated, transactions can be made by converting the issued coin and valuation coin into real coins with real value. Even when consumption information is shared, a blockchain-based verified real purchaser's consumption information sharing service providing method may be provided that sets an expiration date so as to maintain the latestness 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 technical problem, an embodiment of the present invention, when a purchase event occurs according to the payment of goods from the user terminal, transaction specific identification information including payment information, usage information, and personalization information Collecting the transaction information, if the transaction identification information is verified in a blockchain in which the user terminal is included as a node, issuing a registration coin or an evaluation coin for authorizing the registration or evaluation of consumption information in the account of the user terminal; In the case of registering or evaluating consumption information in the user terminal, converting the registered coin or the valuation coin into a real coin to which the preset value is assigned, and the registered coin, the registered consumption information, the valuation coin, and the evaluated consumption information. Mapping, storing and sharing.

According to any one of the above-described means for solving the problem of the present invention, by sharing the correct consumption information by the verified real buyers so that transparent and sincere information can be generated spontaneously, and based on the block chain having the participants as each node It ensures integrity by verifying events or transactions generated by the company, and keeps the shared information up-to-date so that consumption information can be prevented from being distorted by indiscriminate information caused by unspecified unilateral participation. As a tool of advertising internet marketing, lost consumer trust can be restored.

FIG. 2 is a block diagram illustrating a server for providing consumption information sharing service included in the system of FIG. 1. FIG. 3 is a blockchain-based verified consumer information sharing service 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 collecting unit 310, an issuing unit 320, a switching unit 330, a sharing unit 340, and a managing unit 350. .

The consumption information sharing service providing server 300 according to an embodiment of the present invention or another server (not shown) operating in conjunction with the user terminal 100 and the at least one participant terminal 400 have been verified based on blockchain. In the case of transmitting the consumption information sharing service application, program, app page, web page, etc. of the actual purchaser, the user terminal 100 and the at least one participant terminal 400 share the consumption information of the actual purchaser based on the blockchain. You can install or open service applications, programs, app pages, web pages, and so on. In addition, the service program may be driven in the user terminal 100 and at least one participant terminal 400 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 HTML (hyper text mark-up language), for example, Netscape. , Explorer, chrome and the like. In addition, an application means an application on a terminal, and includes, for example, an app running on a mobile terminal (smartphone).

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

In this case, since a person cannot exist in two places at the same time and there can not be two transactions occurring at the same time in the same place of use, when using payment information, place of use information and personalized information, it plays the same role as a unique code that proves the transaction. can do. Accordingly, it can serve as a basis for authorizing the right to prepare or evaluate consumption information, such as a review or a review of consumption, based on a unique transaction record. In this case, the collection unit 310 may be collected when the user terminal 100 uses a payment application, a program, a 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 collection will not be ruled out if it is not used.

If the transaction identification information is verified in the blockchain in which the user terminal 100 is included as a node, the issuer 320 registers for granting authority to register or evaluate consumption information in the account of the user terminal 100. Coins or valuation coins can be issued. In this case, the registered coin and the valuation coin are not the virtual currency that has the value that can be used in the actual transaction, but the coin of the previous stage that can be converted into the real coin that has the value that can be used in the actual transaction. It is defined as the authority to register or evaluate consumption information. However, the registration coin and the valuation coin are not excluded from the virtual currency inherent in the actual transaction.

When the user terminal 100 registers or evaluates consumption information, the conversion unit 330 may convert the registered coin or the valuation coin into real coins to which predetermined values are assigned. That is, in the case where user A purchases A product or purchases A service, user's terminal 100 uses his or her own thoughts or experiences with A as content including text, images and videos. In the case of uploading), the conversion unit 330 converts a registration coin or an valuation coin issued to the user terminal 100 into a real coin, which is an actual virtual currency, so that transactions can be made 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 valuation coin are embedded in the coins 60 and 40 won, respectively 0.6% and 0.4% of the payment amount. In this case, when the user terminal 100 writes a review for the A product or the like, the registered coin is converted into a real coin (60 won) of 60 won. In addition, when the user terminal 100 evaluates the A commodity or evaluates the consumption information (commodity review, etc.) of another person, the valuation coin is converted into a real coin (40 won) of 40 won.

In addition, when the conversion unit 330 registers or evaluates consumption information in the user terminal 100, when the registered coin or the evaluation coin is converted into real coins to which predetermined values are assigned, the user terminal 100 consumes them. If the information is not registered or evaluated, the user terminal 100 is a real coin given 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. 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.

In this case, when the user terminal 100 does not have a registration coin or valuation coin according to a purchase event, or has a registration coin or valuation coin due to a purchase event other than the purchase event, the consumption information according to the purchase event is registered or Can't evaluate For example, when the user terminal 100 purchases the A product, the user terminal 100 is not authorized to register or evaluate consumption information for the B product. To this end, the transaction record may further include information about which goods or services were purchased.

The sharing unit 340 may map, store, and share the registered coin, the registered consumption information, the valuation coin, and the evaluated consumption information. In this way, bloggers who are not actual buyers do not infringe the fair sharing of information by providing sponsored and biased information for marketing for marketing or by operating the comments of employees, employees, etc. who are not actual buyers. That is, since the registration coin or the valuation coin has been granted, it proves that the purchase is made directly, so that it can be authenticated as a real purchaser by mapping and storing and sharing it.

The management unit 350 maps, stores, and shares the registered coin, the registered consumption information, the valuation 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 is present, the registered consumption information and the updated consumption information can be compared. If there is a change in content including addition and deletion of comparison result content, the management unit 350 newly registers updated consumption information, and if there is no change in content including addition and deletion of comparison result content. The validity period of the updated consumption information can be extended. In this case, when the preset validity period of the registered consumption information has elapsed, the registered consumption information may be deleted or deactivated. Accordingly, it is possible to maintain the up-to-date consumption information, and even those who share the consumption information can accurately predict the goods or services that are actually sold by sharing the information closest to the present.

The management unit 350 maps, stores and shares the registered coin, the registered consumption information, the valuation coin, and the evaluated consumption information in the sharing unit 340, and then stores the latest scores of the registered consumption information and the evaluated consumption information. As a result of summing up the latest scores, it is possible to rank the freshness of the consumption information evaluated. In this case, the latest score of the registered consumption information is based on a score that is subtracted in correspondence to the ratio of days that have passed since the registration for the preset expiration date, and the latest score of the evaluated consumption information is after the evaluation of the preset expiration date. It may be based on a score deducted corresponding to the percentage of days that have passed.

At this time, when determining the ranking of the product information, the superiority may be further considered in addition to the latest. In other words, as described above, the deduction system is operated within the expiration date, and excellence is the use of valuation coins. For example, A evaluation has been registered for 1 month, and there are two evaluation information of others. If 20 days have passed with rating 1 on 4 stars and 10 days with rating 2 on 3 stars,

Latest registration: 100 points × (3 months-1 month) ÷ 3 months (* 1 month is the elapsed month, 3 months is valid)

Is calculated as

1 rating: 1 point × [5-(5-4)] × (30 days-10 days) ÷ 30 days (* 5 is MAX by rating, 4 is rating by rating, 30 days is valid, 10 days elapse Days)

2nd evaluation score: 1 point × [5-(5-3)] × (30-20 days) ÷ 30 days (* 5 is MAX by rating, 3 is rating by rating, 30 days is valid for evaluation, 20 days elapse Days)

It can be calculated as That is, additional compensation for the ranking is given to the product information registrant and the evaluator, which is a process of allowing users to select and manage reliable consumption information by themselves.

On the other hand, at least one data including collection of transaction identification information, issuance of a registration coin or valuation coin, and conversion of real coins may be verified at at least one node included in the blockchain. Of course, verification may occur in various steps in addition to the above-described process. In addition, a transaction between at least one node included in the blockchain may be made by a smart contract. In this case, the blockchain of the present invention may be composed of four basic technologies such as peer-to-peer (P2P) networks, encryption, distributed ledger, and distributed consensus. Each technology is complementary to the decentralization, which is the value of blockchain, and to maintain the integrity of data, and forms the basis of the blockchain operation mechanism. On the other hand, smart contract, which is an application technology in a blockchain environment, is a technology that provides integrity and reliability of an execution code and a result of a program, 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 composed of equally layered participants who are separated from the existing client-server method, and largely 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 of network among participants and a flooding algorithm of data. For decentralized distributed networks, flooding-based unstructured P2P networks can be used, and the communication of P2P networks is usually through UDP, but the blockchain uses TCP / IP. Therefore, the participants in the blockchain maintain the IP of the participants who are physically closest to themselves and can use them to send and receive messages and data.

Encryption technologies include, but are not limited to, a Merkle Tree for data integrity verification and a public key-based digital signature technique for nonrepudiation of transactions. Merkle tree is a kind of hash tree, in which the names of all non-leaf nodes consist of hashes of child nodes, that is, leaf nodes refer to data such as files and specific values, and the parent node is a tree composed of hashes of the leaf nodes. The root node of the Merkle tree constructed in this way consists of the hash values of the data of all the leaf nodes that make up the tree, and the user can verify the forgery and corruption of the data only by verifying the hash of the root node. In addition, the public key-based digital signature scheme is an encryption technology that enables secure communication between participants who do not share a secret key in advance, and is widely used in fields such as identity authentication. In the public key infrastructure, there are two key pairs, a public key and a secret key. The public key is known to all participants, but the corresponding secret key remains known only to its owner. Blockchain is used to validate transactions.

Thirdly, the distributed ledger is a repository of information that is replicated, shared, and synchronized by consensus among the participants. In particular, the distributed ledger requires consensus of the participants on the records of the distributed ledger in order to be applied on a P2P network. The blockchain also retains its characteristics. In the blockchain, the distributed ledger records all transactions and information generated through the verification process of the participants, and all participants maintain the same information. When verifying transactions 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 legal transactions or information are stored in the distributed ledger of the blockchain. When storing transactions or information, they are accumulated for a certain period of time and stored in units called blocks, and stored in a distributed ledger with connectivity between the blocks. This distributed ledger is the foundation of data integrity guarantee provided by the blockchain, and all users participating in the blockchain maintain the same distributed ledger data so that an attacker attempts to forge a specific data or do a double transaction from the outside. In order to do so, it is necessary to try to attack more than half of the distributed books held by the participants, which requires high cost and computing resources, thereby reducing the risk of forgery or double trade.

Fourth, distributed consensus is a protocol that derives agreement on specific data values between processes or agents in order to achieve overall system reliability when there are defective processes in distributed computing and multi-agent systems. The protocol has the following properties. First, validity, that is, if all the correct processes offered the same data, then all processes make a decision (valid, invalid) on the proposed data, and then integrity, that is, all the correct processes If data has been adopted, the data is the data proposed by another process, and agreement, that is, all correct processes must agree on what data, and termination, i.e. all valid processes, on what data Is to make a decision. In the blockchain, we design the distributed consensus protocol and draw consensus among participants on the transactions or information generated through the above, and only the appropriate transactions or information are maintained in the blockchain through the agreement, Consensus algorithms such as of-work or Proof-ofstake, Delegated Proof-of-Stake, and Practical Byzantine Fault Tolerance (PBFT) -based Tendermint may be used, but are not limited thereto.

Finally, smart contracts are defined as computer transaction protocols that enforce contract terms and automate between trading parties without an intermediary or central authority by minimizing the broker for trust in the transaction while meeting the contract terms and minimizing malicious exceptions. Direct transaction, which ensures the reliability and integrity of transaction information by maintaining both the terms and results in a distributed ledger. In other words, the user can program the protocol smart contract containing the desired condition and store it in the blockchain. If the specific condition is satisfied, the smart contract is verified and executed by other blockchain participants. Execution results are again stored in the blockchain to ensure the integrity and reliability of the information on the transaction results.

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

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

Then, (b) the consumption information sharing service providing server 300 issues a registration coin and an evaluation coin to the user terminal 100 to share the consumption information for the purchase of the ice americano, and transmits it. In this case, (c) when 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 real coin, thereby enabling trading. It is converted into money. Similarly, when (d) the user terminal 100 evaluates consumption information (late reviews, etc.) of another person's ice americano purchased at the coffee shop A, the valuation coin held in the user terminal 100 is converted to real coins. As a result, it becomes a tradeable cryptocurrency. On the other hand, (e) even if the consumption information is not registered or evaluated in the user terminal 100, at least one participant terminal 100 for a plurality of transactions generated by generating a transaction or being given a real coin If computing resources or network resources are provided as a node in the blockchain by performing operations to ensure integrity, this also causes the conversion of registration and evaluation coins into real coins.

In this way, if the consumption information is uploaded, shared and evaluated, (f) the consumption information sharing service providing server 300, since the verification of the consumption information is completed, to determine whether the update of the consumption information occurred to maintain the latest Consumption information that is past its expiration date should be discarded or deactivated, and even if an update (addition, deletion, etc.) has not occurred, simply re-registering will extend the preset expiration date. In addition, the consumption information sharing service providing server 300 determines whether the evaluation is recent, and as the evaluation date elapses from the present and the registration date elapses 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.

As described above with reference to the method of providing the consumption information sharing service of the verified real buyer of the blockchain based on FIG. 2 and FIG. 3, the method of providing the consumption information sharing service of the actual buyer verified by the blockchain through FIG. 1 is described above.

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

Referring to FIG. 4, when a purchase event occurs in the user terminal 100 (S4100), the consumption information sharing service providing server 300 collects transaction identification information (S4200) and through each node in the blockchain. The transaction is verified (S4300) and a registration coin and an 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 is converted to the value according to the registration or evaluation (S4710) ), The registered coin or valuation coin is converted into real coin (S4730), and if consumption information is neither registered nor evaluated, the value is converted according to the provision of resources to provide a reward for providing the resource as a node in the blockchain. By (S4720), registered coins and valuation coins are converted to real coins (S4730, S4740).

On the other hand, the consumption information sharing service providing server 300 shares the registered consumption information or the evaluated consumption information (S4800), and if the expiration date of the consumption information has not passed (S4810, S4830) If it has passed, the registered consumption information is deleted or inactivated (S4820). If consumption information is updated within the valid period (S4840), if the contents are actually edited (added, deleted, etc.), the consumption information is newly registered (S4870). Since it is the case of registration (simple registration) (S4850), the validity period is extended (S4860). In addition, when the consumption information sharing service providing server 300 calculates the ranking score in order to secure the latestness of the evaluation of the consumption information, it is possible to induce continuous new registration and evaluation by adding the latest score on the registration date and the latest score on the evaluation date. It may be (S4900).

The order between the above-described steps S4100 to S4900 is merely an example, and is not limited thereto. That is, the order between the above-described steps (S4100 to S4900) may be mutually changed, and some of the steps may be executed or deleted at the same time.
