Description

Blockchain-based anomaly detection device and method

The present invention relates to an apparatus and method for detecting anomalies based on a block chain, and more particularly, to an apparatus and method for detecting anomaly in an operation between nodes of a block chain network.

Recently, interest in bitcoin, a type of digital cryptocurrency that allows payment in kind, has emerged.

Bitcoin is a digital currency created by Satoshi Nakamoto in 2009, and has a structure that does not have a central device for issuing and managing the currency. Instead, bitcoin transactions are performed by a distributed database based on a peer-to-peer network, and transactions are usually performed using a public key encryption algorithm.

As such, digital cryptocurrencies that can be paid in kind include Bitcoin, Litecoin, Darkcoin, Namecoin, Pottery Coin, Ripple, etc., and their common characteristics are that traders use digital cryptocurrencies including Bitcoin. Thus, the ledger of the transaction details is stored in the electronic wallet. The ledger of transaction details is sequentially connected according to blockization and hash conversion in a certain unit, and can be shared on the blockchain network in a form that can be verified by hash comparison.

Individual blocks connected to such a blockchain may be sequentially connected according to hash transformation, and may be configured in the form of a data packet including a plurality of pieces of information. For example, the information included in the block may be a transaction history in which participants traded currency, a hash value of a previous block, a difficulty level, a nonce, and the like. Each block contains the hash value of the previous block, and the blocks connected in this way can form a single blockchain that contains transfer details that occurred in chronological order.

When such a blockchain network is formed, a single transaction ledger can be shared through nodes connected to the network. The shared transaction ledger can be preserved by a blockchain that is verified and formed by a number of unspecified nodes. Since such a transaction ledger is continuously verified and preserved by all node terminals connected to the network, forgery of the transaction ledger is prevented by the majority of nodes that want to maintain the transaction system.

In addition, the target of such an attack on the blockchain network, such as hacking, must be the transaction system itself consisting of a number of unspecified nodes, not a specific terminal, and the action itself destroys the transaction system itself, so it is a benefit against the cost of hacking. Due to its low value, hacking itself can be prevented in advance. Therefore, it is possible to establish a reliable distributed transaction of cryptocurrency without separate central control.

However, it is very difficult to lead to active use in the actual economy due to the inconvenience of actual use of cryptocurrencies formed on the basis of such a block chain due to instability of its value and delay in approval time caused by the limitations of the blockchain network system. . In addition, due to its instability and anonymity, there are cases of legally restricting its use at the national level.

In particular, in order to solve the underlying cause of value instability, the cryptocurrency formed by the blockchain network is secured in a specific legal currency or other cryptocurrency, and as a result, its value becomes the same as the legal currency. STABLE COIN) is also being proposed.

However, the security stabilization methods proposed to date require another currency as collateral, and thus have the same volatility as the value volatility of the other currency, so that the value volatility is transferred and secured. The actual problem has not been solved. In addition, excessive stabilization lowers the profitability of holdings or the necessity for currency transactions, thereby reducing the number of holders, thereby reducing usability.

In other words, a fundamental problem is still being raised that cannot bring about the stabilization of the value of the cryptocurrency itself, the creation of value through transactions and the improvement of usability in real economic life.

Meanwhile, beauty and treatment services using stem cells are emerging as an alternative to treat incurable diseases that cannot be cured in medicine. This stem cell service enables a banking service that extracts, cultures, and stores adult stem cells and immune cells of adults. These stem cell banking services can be used to treat various diseases, strengthen immunity, anti-aging treatments for cosmetic purposes, and treat incurable diseases according to the development of medical technology in the future.

All of these may be included, but the present invention is not limited thereto, and may be various devices capable of user input and information display.

To this end, each trader terminal 10 may be equipped with a communication module for accessing a blockchain network. The blockchain network may be implemented as a wired network such as a local area network (LAN), a wide area network (WAN), or a value added network (VAN). In addition, blockchain networks include mobile radio communication network, satellite communication network, Bluetooth, Wireless Broadband Internet (Wibro), High Speed Downlink Packet Access (HSDPA), Wi-Fi, and Long Term (LTE). Evolution) can be implemented in all types of wireless networks. If necessary, the blockchain network may be a mixed wired and wireless network.

In addition, each trader terminal 10 may register account information according to its own node access to transaction book data shared in a cloud manner through a network. In addition, when a cryptocurrency transaction is required, each trader terminal 10 may propagate the transaction information to be recorded in the transaction book data to the other trader terminal 10.

In addition, each trader terminal 10 can use a pre-shared smart contract (SMART CONTRACT) on a blockchain network by processing a specific transaction system process so that it cannot be forged or altered based on the transaction book data. Such a smart contract may include a transaction system process that is block-chained so that post-forgery/alteration is impossible, attributes for each cryptocurrency defined accordingly, conditions for issuance, conditions for transactions, conditions for incineration, and information about setting rights for each trader.

In addition, when a process based on a smart contract is processed or approval processing corresponding to a cryptocurrency transaction, for example, approval from a node terminal of a certain ratio or more is processed, the transaction book data is updated, and the updated transaction book data is By sharing, cryptocurrency transactions and execution of smart contracts can be processed.

Here, the transaction book data is a block chain having a structure in which a plurality of blocks are sequentially connected according to the order of creation by including the hash value of the block previously generated by the current block for each block corresponding to a certain time or unit. chain) can be linked with data.

Accordingly, verification of forgery or alteration of transaction book data can be easily processed according to the verification of the hash value of the blockchain. To this end, each trader terminal 10 may provide computing power to perform calculation and verification processing for calculating a hash value of a subsequent block, and may obtain a corresponding reward.

The security stability of such a blockchain can be formed by the participation of traders sharing data in the system. Therefore, transaction information blocks including details of sharing and currency issuance/transaction details, etc. between each trader terminal 10 connected to the blockchain network can be sequentially stored, and hash values for preventing the forgery are sequentially stored. Transaction verification (proof-of-work) processing for block chaining can be distributed in each trader terminal 10.

Accordingly, referring to FIG. 2, each processing unit and modules of the system according to an embodiment of the present invention use the block chain network 50 configured as the main network, and a decentralized application based on a smart contract (DECENTRALIZED APPLICATION). It can be implemented as

In particular, the exchange service providing device 100 constituting this may issue, transact, convert, and manage the first cryptocurrency based on the main network (that is, the block chain network 50) and the stem cell value-linked membership license. . In addition, the exchange service providing apparatus 100 may provide a transaction service between other cryptocurrencies previously issued based on the main network (ie, the block chain network 50), and a transaction service between legal currencies. In addition, the exchange service providing apparatus 100 may provide a real value exchange and incineration process of the real value-linked membership usage right. The exchange service providing apparatus 100 will be described in more detail later.

Referring to FIG. 2, an exchange system according to an embodiment of the present invention includes an exchange service providing apparatus 100 and a trader terminal 300 based on a block chain network 50.

The exchange service providing device 100 is connected to the payment preparation rate control module unit 400, the membership service providing device 200, the stem cell service server 500 and the medical server 600, and exchanges according to an embodiment of the present invention. It can provide processing, transaction services, and membership services related to stem cells.

More specifically, the exchange service providing apparatus 100 may issue a first cryptocurrency issued and distributed based on a distributed transaction. The issued first cryptocurrency data may be distributed to the trader terminal 300. The trader terminal 300 processes the purchase/sale of the first cryptocurrency as another legal currency or cryptocurrency, or the membership use right according to the stem cell service value conversion ratio corresponding to the first cryptocurrency through the exchange service providing device 100 You can request a conversion.

In addition, the exchange service providing apparatus 100 may issue a membership usage right according to a request for conversion to a membership usage right and pay it to the corresponding trader terminal 300. Here, the membership usage right may be issued under a condition that can be incinerated by a service provision process corresponding to the stem cell service value according to a process for preparing the payment of the stem cell service value.

The stem cell service value represents the actual value of the stem cell-related service, and the stem cell management service provided through the stem cell service server 500 from the membership service providing device 200 and the medical server 600 It can be linked to the value of stem cell therapy or cosmetic services.

Here, the stem cell management service may be provided through the stem cell service server 500 at the request of the membership service providing device 200. The stem cell management service may include storage and banking management, separation, cultivation, differentiation, stem cell screening, and customized stem cell treatment plan services of stem cells registered in membership.

Further, the stem cell treatment or beauty service may be provided through the medical server 600 at the request of the membership service providing device 200. Stem cell treatment or beauty service is provided with stem cells differentiated and cultured in a form necessary for treatment or beauty among stem cells managed by the stem cell service server 500, and stem cell-based immune cell treatment and skin regeneration procedures provided to traders , Anti-aging procedures, new clinical procedures, and various other stem cell-related treatments or cosmetic services.

To this end, first, the trader terminal 300 may perform membership user registration for the membership service providing device 200 via the exchange service providing device 100.

Membership user registration may be processed according to distributed security authentication between the trader terminal 300, the exchange service providing device 100, and the membership service providing device 200. In addition, the user personal information, medical record information, membership management information, and reward information registered according to the distributed security processing are partially in the trader terminal 300, the exchange service providing device 100, and the membership service providing device 200, respectively. By being distributed and stored and managed by multi-authentication, it is possible to improve the security of medical records management according to future stem cell service provision.

Meanwhile, in order to use the stem cell service according to membership registration, the user of the trader terminal 300 may first purchase the first cryptocurrency through legal money or other cryptocurrency through the exchange service providing device 100. In addition, the trader terminal 300 may use the first cryptocurrency to exchange it for membership usage rights. The exchange rate of membership usage rights may be linked to the value of the stem cell service managed by the payment preparation rate control module unit 400.

Here, the value of the stem cell service linked to the membership right may be determined according to the value calculation of stem cell-related services provided from the stem cell service server 500 and the medical server 600. In particular, the increase in value due to the development of stem cell treatment services can lead to an increase in the value of membership rights, and even treatments that are in clinical trials may increase the value according to the clinical stage. In addition, a payment for the first cryptocurrency exchange of the membership right may be deposited, and this may be used to improve the value of stem cell services such as research on stem cell-related therapy or new drug development through the membership service providing device 200. have.

In addition, the user of the trader terminal 300 may transmit a service provision request corresponding to the purchased membership usage right to the exchange service providing apparatus 100. When a service provision request is received, the exchange service providing apparatus 100 transmits request data corresponding to service provision to the membership service providing apparatus 200. In addition, the membership service providing device 200 makes a request to provide a service for allowing the stem cell service corresponding to the level or quantity of the membership license to be provided to the user of the trader terminal 300, the stem cell service server 500 or the medical server ( 600).

For example, so that the stem cell management service is provided to the user of the trader's terminal 300, the membership service providing device 200 manages storage and banking of stem cells, separation, culture, differentiation, stem cell examination, and customized stem cell treatment. The plan service request may be transmitted to the stem cell service server 500. In addition, so that the stem cell treatment or beauty service is provided to the user of the trader terminal 300, the membership service providing device 200 differentiates and cultures the stem cells managed by the stem cell service server 500 into a form necessary for treatment or beauty. By receiving the obtained stem cells, it is possible to request from the medical server 600 for stem cell-based immune cell treatment, skin regeneration treatment, anti-aging treatment, new clinical procedure, and various other stem cell-related treatment or beauty services provided to traders.

In order to provide such stem cell-related services in a more efficient and secure form, the membership service providing device 200 includes a personal information management module unit 210, a medical record management module unit 220, and a membership management module 230. ), a distributed security module unit 240, a reward module unit 250, a service recommendation module unit 260, and an anomaly detection module unit 270.

The personal information management module unit 210 may manage personal information of each user registered in membership. For example, the personal information of each user may include the user's name, age, gender, and desired service. Here, the desired service may be a stem cell management service, a stem cell treatment, or a beauty service.

If necessary, the above-described desired service may additionally include an anti-aging service, a healthcare service, and a cosmetic service. Anti-aging services may include botox, laser treatment, contour injection, thread lifting, lifting laser, filler, DNA injection, collagen injection, MTS treatment, and air jet lifting. Health care services may include health counseling, genetic testing, dispatch of caregivers, nursing hospitals, nutritional diets, and preventive vaccines.

The personal information of each user of the personal information management module unit 210 may be distributed and stored in the trader terminal 300 and the exchange service providing device 100 by the distributed security module unit 240 for security.

The medical record management module 220 may manage personal medical record information of each user registered in membership.

In particular, since personal medical record information for each user is important, in order to maximize security, personal medical record information for each user is divided into two sections, and a part of the personal medical record information for each user (eg, the first section) is The record management module unit 220 manages, and the rest of the personal medical record information for each user (eg, the second section) is stored in the safety box 800 on the blockchain network 50 by the distributed security module unit 240 do. Data in the medical record management module unit 220 and the safety box 800 are safely managed through a zero-knowledge proof.

Meanwhile, in order to check the entire data of user 1's personal medical record information, for example, both data in the medical record management module unit 220 and the safety box 800 are required. Accordingly, it is necessary to access the medical record management module unit 220 and the safety box 800, and for this purpose, an accessor in the medical record management module unit 220 and the safety box 800 (for example, a user of a trader terminal, Medical center administrators, etc.), multisignature is required for authentication. In this process, it is impossible to expose personal medical record information without the consent of the user. Here, the personal medical record information of each user includes, for example, genetic information, NK index, healthy age, diseases with factors to develop, immunity index, anti-aging index, stem cell treatment history, stem cell beauty service history, etc. Can be included.

The safety box 800 is connected to the blockchain network 50 separately from the exchange service providing device 100, the membership service providing device 200, and the trader terminal 300.

The membership management module unit 230 may manage membership usage rights purchased by a user.

In particular, when a user uses a membership right corresponding to a specific service from among the membership usage rights purchased by the user, the membership management module unit 230 may deduct the user's existing membership usage right by the amount used. In addition, when a user additionally purchases a membership license, the membership management module unit 230 may increase the amount of use of the existing membership license based on the purchase amount.

As described above, the membership management module unit 230 may manage information that enables the user to know for what purpose the membership right is used and the current usage of the membership right for each user. The information that allows the user to know the purpose of the membership usage right and the current usage of the membership usage rights for each user may be collectively referred to as membership usage rights information for each user.

Membership usage rights information for each user of the membership management module unit 230 may be distributed and stored in the trader terminal 300 and the exchange service providing apparatus 100 respectively by the distributed security module unit 240 for security.

The distributed security module unit 240 includes personal information for each user of the personal information management module unit 210, personal medical record information for each user of the medical record management module unit 220, and a membership right for each user of the membership management module unit 230 Information and reward information for each user of the reward module unit 250 may be distributed and stored in the trader terminal 300 connected to the blockchain network 50 and the exchange service providing device 100, respectively.

In particular, the distributed security module unit 240 stores the rest of the personal medical record information for each user partially stored in the medical record management module unit 220 in the safety box 800 on the blockchain network 50. This is to maximize security because personal medical record information for each user is important as described above.

The reward module unit 250 compensates for a portion (reward) of a stem cell management service, stem cell treatment, or sales of beauty services through air drop, and manages reward information for each user.

That is, when a user holding the first cryptocurrency accesses the exchange service providing device 100 through a dedicated cryptocurrency wallet and purchases a membership license corresponding to a desired stem cell management service, stem cell treatment or beauty service, The exchange service providing apparatus 100 deducts the quantity of the first cryptocurrency corresponding to the membership right.

In other words, the first cryptocurrency is converted to a membership license according to a certain amount of conversion and a conversion rate, and the conversion rate at this time corresponds to the transaction price of the first cryptocurrency and the membership license, and exchangeable stem cell management service, stem cell treatment, or It was determined according to the market price information of the value of beauty services. Accordingly, the amount (amount) of the first cryptocurrency corresponding to the membership right used to purchase the stem cell management service, stem cell treatment, or beauty service must be deducted from the user's dedicated cryptocurrency wallet. Instead, the reward module unit 250 provides a portion (reward) of the profit generated by the sale of the stem cell management service, stem cell treatment, or beauty service to the user through air drop.

In the above, it is assumed that the reward module unit 250 provides some of the profits generated by the sale of stem cell management service, stem cell treatment, or beauty service to the user. However, other than stem cell management service, stem cell treatment, or beauty service Some of the profits generated by the sales of anti-aging services, healthcare services, cosmetic services, etc. may also be provided to the user.

Meanwhile, the reward information for each user of the reward module unit 250 may be distributed and stored in the trader terminal 300 and the exchange service providing device 100 by the distributed security module unit 240 for security.

Each of the above-described module units 210, 220, 230, 240, and 250 may store and manage data processed through security between module units. And, each module unit (210, 220, 230, 240, 250) only shareable transaction information (e.g., first currency usage information, membership purchase information, usage information, simple transaction information such as incineration information) is a blockchain network. By writing in the transaction book of (50), the remaining sensitive information can be kept secure.

Meanwhile, since the first cryptocurrency can be traded between other cryptocurrencies and legal money, its value volatility may be relatively high. However, since the first cryptocurrency enables the provision of stem cell services according to the conversion to the membership right, the value volatility is stable and controllable by adding value linkage by providing the stem cell service.

In addition, the number and amount of membership rights may be determined according to the value of stem cell services. Since the exchange service providing apparatus 100 can process the payment preparation process for the issuance in advance, the user can use the membership right at any time to provide the stem cell service. Accordingly, the right to use the membership service provided may be incinerated.

In addition, the exchange service providing apparatus 100 may perform a conversion process to a membership usage right corresponding to the first cryptocurrency transaction price according to the stem cell service value calculated by the payment readiness rate control module unit 400. In addition, the exchange service providing device 100 transmits a request for providing a stem cell service corresponding to the membership use right to the device 200 for providing a membership service, or transmits a request for providing a service processed according to the payment preparation process to the stem cell service server ( 500) or directly to the medical server 600.

Accordingly, the trader's terminal 300 holds the right to use a distributed transaction book-based membership that can be provided as a service at any time according to the development of stem cell treatment technology, so that more efficient stem cell related services can be provided, and also an effective asset. It can also be used as a management means.

On the other hand, the payment readiness control module unit 400 converts the first cryptocurrency issued and circulated by the exchange service providing device 100 into a membership license, and a stem cell service provision process of the membership license accordingly. It is possible to calculate the payment readiness rate and the value of stem cell services that enable them. In addition, as the payment preparation ratio adjustment module unit 400 is maintained, the payment preparation ratio can be analyzed and adjusted for the amount of cryptocurrency circulation and the payment reserve to maintain the stability of the trading platform and system.

The payment readiness control module unit 400 may determine whether or not payment preparation is necessary based on the stem cell service value prediction model, or conditionally determine a policy process corresponding to the need for payment preparation, and according to the appropriate policy decision and execution for each situation. Fundraising processing to a financial server (not shown) can be further performed.

For example, the payment readiness control module unit 400 calculates the cost of storage, culture, differentiation and examination of stem cells for each membership level, stem cell treatment, beauty, and clinical costs, and a certain percentage of insurance premium corresponding to each service. Can be calculated. In addition, the payment readiness rate control module unit 400 combines the ratio and funding information corresponding to the total amount of currently issued membership rights to the total amount of service and insurance premiums, and between the membership rights linked to the stem cell service value market price, and the first cryptocurrency. Exchange rate can be determined.

According to such a system, the first cryptocurrency can be stably issued and distributed, and can be converted into a membership license linked to the value of stem cell service. Membership usage rights can be converted into stem cell services at the time of need, so this can create value through transactions while stabilizing the value of the cryptocurrency itself by the value of stem cell services. In addition, membership usage rights can provide a cryptocurrency issuance, management, and transaction platform that enables users to share added value according to the development of medical technology through distributed processing based on a blockchain network.

In the above-described FIG. 2, the exchange service providing device 100 and the payment readiness control module unit 400 are separately configured, but if necessary, the payment readiness control module unit 400 is included in the exchange service providing device 100. It is okay to do it.

In addition, the control unit 130 may provide processing of transaction information requested to the block chain network 40. On the other hand, the control unit 0 may process processes such as issuance of cryptocurrency, transaction, currency conversion, stem cell-related service provision, and incineration through the exchange service processing unit 110 based on the blockchain network 5. .

In particular, the control unit 130 may share cryptocurrency transaction information according to exchange service processing on the blockchain network 50. According to the corresponding approval result, cryptocurrency transaction information may be updated in the transaction book data.

The process for the cryptocurrency processing of the exchange service processing unit 110 may be pre-registered in the form of a code such as a smart contract in the transaction book data shared on the blockchain network 50, and forgery accordingly Can be prevented.

More specifically, the first cryptocurrency management unit 111 performs issuance of the first cryptocurrency and management of the holding amount according to the transaction service.

In issuing the first cryptocurrency, the first cryptocurrency management unit 111 may divide and manage the initial issuance amount into a central bank holding amount, an internal holding amount, and an external holding amount. For example, 50% of the initial issuance amount may be determined as the central bank holding amount, the remaining amount may be determined as the circulation amount, and half of the circulation amount may be circulated and managed as the internal holding amount and the rest as the external holding amount.

The central bank holding amount and the internal holding amount are quantities necessary for the payment preparation unit 114 to control and manage the payment preparation ratio. For example, the central bank holdings can be transferred to a central bank account with separate storage rights, so that distribution and transactions can be managed in a restricted state. The internal holding amount is a circulating quantity and can be transferred and managed to a manager account.

And, the external holding amount is the holding amount circulated to the trader terminal 300, and may be a target of the sale or purchase process by the legal currency transaction service unit 117 and the cryptocurrency transaction service unit 118, and accordingly Traders may normally be able to buy/sell external holdings.

Here, the legal currency transaction service unit 117 and the cryptocurrency transaction service unit 118 may process a first cryptocurrency transaction service corresponding to the legal currency or other cryptocurrency, respectively. That is, the legal currency transaction service unit 117 and the cryptocurrency transaction service unit 118 may determine the transaction price between the legal currency of the first cryptocurrency and the transaction price between the first cryptocurrency and other cryptocurrencies, respectively, and 1 Purchase/sell cryptocurrency or exchange services for other cryptocurrencies can be provided.

Here, in the first cryptocurrency, a transaction price may be formed by autonomous transactions between each seller and buyer in the exchange. The legal currency transaction service unit 117 and the cryptocurrency transaction service unit 118 exchange the first cryptocurrency held in the user's account for legal currency or other cryptocurrency, or exchange the legal currency or other cryptocurrency held in the first cryptocurrency. It is possible to directly provide a transaction service that allows it to be exchanged for currency, or it can also provide a transaction brokerage service that brokers transactions through other exchanges.

Accordingly, the first cryptocurrency has a market value determined by autonomous transaction by a transaction service and may have inherent volatility. In addition, the first cryptocurrency may be converted into membership usage rights as much as possible.

In addition, since the membership license according to an embodiment of the present invention is used by providing stem cell-related services, the value of the membership license may be the same as the stem cell service value, and the volatility of the real value may be low or gradually improved. .

For example, the number of available membership rights may be determined according to the membership level and service, and the value of stem cell service for a certain unit quantity of membership rights is determined by each service (stem cell management such as stem cell storage, culture, differentiation, and examination). Service, stem cell treatment, treatment, beauty, clinical, etc. stem cell treatment and cosmetic services, etc.).

On the other hand, the transaction price of the first cryptocurrency may fluctuate in real time, and the exchange rate for membership usage rights and the convertible quantity may vary.

For example, if yesterday's transaction price was able to convert the membership right for the value of one stem cell treatment per unit quantity of the first cryptocurrency, as the transaction price of the first cryptocurrency rises, today the unit quantity is 2 The conference stem cell treatment value can be converted into a membership license.

On the other hand, membership usage rights are expected to have the same or gradual increase in the value of one stem cell treatment, and the volatility can have a stable form.

Therefore, even if there is market value volatility of the transaction price of the first cryptocurrency, the change in real value can be controlled by stable volatility of the membership right. Accordingly, rapid inflation or deflation is prevented, and value volatility can be adjusted and the trading system can be stably maintained.

In addition, as the value of stem cell services is improved by securing funds, the utility of the entire system increases, so that profits between traders and service providers can be created.

To this end, according to an embodiment of the present invention, the first cryptocurrency may be converted into a membership right according to a predetermined conversion amount and conversion rate. In addition, the conversion rate may be determined according to market price information of the exchangeable stem cell service value corresponding to the transaction price of the first cryptocurrency and the membership right.

For example, when the real value that can be exchanged in a certain unit of a membership license is referred to as a one-time stem cell storage service, the first cryptocurrency may be converted into a membership license by a certain amount corresponding thereto. A certain amount may be determined according to the value of a one-time stem cell storage service that can be exchanged for a membership license, and the number of the first cryptocurrency that can be converted to a membership license may differ depending on the authority and level of the user requesting the conversion.

In addition, the exchange rate from the first cryptocurrency to the membership license may be calculated by the first cryptocurrency transaction price, the type of available stem cell service by grade, and the price of the stem cell service value. 1 The number of membership license conversion per cryptocurrency unit = (Type of available stem cell service) × (Stem cell service value market price) / (First cryptocurrency minimum transaction price per transaction unit)].

Then, the membership use right management unit 112 performs issuance and retention amount management processing of the membership use right.

In particular, the membership usage right management unit 112 may calculate the amount of issuance of the membership usage right according to the payment preparation information of the payment preparation unit 114. For example, the payment preparation information is payment reserve information, and may include price information of a stem cell service that can be provided. The membership usage right management unit 112 may calculate an issuable amount as much as the amount capable of providing stem cell services while maintaining a certain holding amount based on the payment reserve. For example, the amount available for issuance may be adjusted to maintain a predetermined ratio or more with respect to the market cap of the first cryptocurrency in which payment reserves are circulated. In addition, the membership usage right management unit 112 may issue a membership usage right that can be issued on a condition that can be incinerated by a value payment or exchange process corresponding to the value of a stem cell service.

In addition, the membership usage right may be issued according to a request for currency conversion corresponding to the first cryptocurrency from the trader terminal 300.

To this end, the currency conversion processing unit 113 pre-calculates the convertible amount according to the payment preparation information, determines the number of convertible membership licenses among the first cryptocurrency, and provides them to the membership license management unit 112 and the trader terminal 300. I can.

Accordingly, the membership usage right management unit 112 may issue membership usage rights equal to the amount determined by the currency conversion processing unit 113, and the issued membership usage rights can have a service provision value for using stem cell related services. .

Meanwhile, the stem cell-related service providing unit 115 may transmit a service provision request corresponding to a specific service to the membership service providing device 200 as the service provision request of the membership usage right is received from the trader terminal 300.

For example, the stem cell-related service providing unit 115 deducts the usage right corresponding to the amount of use corresponding to a specific service among the membership usage rights, and provides request information to provide the stem cell-related service to the user of the corresponding trader terminal 300 May be delivered to the membership service providing device 200. In addition, the stem cell-related service provider 115 receives in advance the qualification information or personal identification information corresponding to the trader's membership registration from the trader's terminal 300, delivers it to the membership service providing device 200, and provides the service. It can be used for pre-verification.

Meanwhile, the stem cell-related service providing unit 115 may receive a gender, age, and a desired purpose from a user who wishes to receive a stem cell-related service and transmit it to the service recommending unit 121.

Accordingly, the service recommendation unit 121 recommends the best suitable stem cell-related service (ie, stem cell management service, stem cell treatment or beauty service) for the user based on the gender, age, and desired purpose of the delivery. I can. In other words, when a user of the trader's terminal 300 (ie, a user who wants to receive a stem cell-related service recommendation) enters his or her gender, age, and desired purpose, the stem cell-related service provider 115 recommends the service. Pass it to the part 121. The service recommendation unit 121 may recommend the most suitable and optimal stem cell related service based on the received information. Thereafter, when the user approves to receive the recommended stem cell-related service, the service recommendation unit 121 provides a membership service with provision request information that enables the stem cell-related service to be provided to the user of the corresponding trader terminal 300. It is sent to the device 200. Accordingly, the membership service providing apparatus 200 deducts the membership usage right corresponding to the amount corresponding to the corresponding stem cell-related service, and requests the stem cell service server 500 to provide the stem cell-related service. As a result, the user can receive the most suitable procedure (ie, stem cell-related service).

If necessary, when a user registered for membership (i.e., a user who wishes to receive a stem cell related service recommendation) enters information such as age, gender, and desired purpose, the stem cell related service provider 115 receives the received information. Is sent to the service recommending unit 121, and the service recommending unit 121 transmits the received information to a plurality of partners (not shown) again, and the plurality of partners (not shown) transmits the received information to the information input by the user. Each service condition can be presented. In addition, the service recommendation unit 121 ranks the service conditions suggested by a number of partners (not shown) according to which service conditions are most suitable for the user, and based on this, a stem cell-related service suitable for the user. You can also recommend In this case, the service recommendation unit 121 may present (recommend) only one service condition as a stem cell related service, or may present several service conditions for each priority.

In the above, it has been described that the service recommendation unit 121 can recommend a stem cell-related service suitable for the user, but if necessary, general procedures (eg, botox, laser treatment, contour injection, thread lifting, lifting laser, filler, Users can also recommend suitable services for DNA injection, collagen injection, MTS treatment, air jet lifting, health counseling, genetic testing, dispatch of caregivers, nursing hospitals, nutritional diet, preventive vaccines, etc.).
