{System Providing Virtual Money Managerial System}

More particularly, the present invention relates to a virtual money management system based on a block chain, which is capable of issuing a public key and a symmetric key separately so that a quick verification and a differentiated encryption algorithm The present invention relates to a virtual money management system in which security can be continuously verified at all times.

Generally, in the case of the proposed virtual currency, the online game goods surrogate purchase apparatus and method using the virtual money for the PC room manager disclosed in the Korean Intellectual Property Office (Patent Publication No. 10-2012-0028519) There is a problem in usage because it can be used only for purchasing items in a game.

Recently, Bitcoin, a kind of virtual money that can be paid for in-kind, has been proposed.

Bitcoin is a digital currency created by Satoshi Nakamoto in 2009, and has a structure that does not have a central device to issue and manage currency. Instead, the transaction of the bit coin is performed by a distributed database based on peer-to-peer network (P2P), and transactions are performed based on the public key cryptography.

Such a bit coin having a payment method has an advantage not only in that it can be used without information such as a card number, an expiration date, and a CVC number necessary for a credit card settlement, but also a usage fee is cheap. In addition, the bit coin is stored in an electronic wallet in the form of a file, and each electronic wallet is assigned a unique address, and the bit coin transaction is performed based on the address.

In order to use the bit coin having the settlement characteristic, the bit coin user first subscribes to the bit coin exchange and charges the KRW corresponding to the won with the electronic wallet opened.

Then, after confirming the current price of the bit coin being traded at the bit coin exchange and entering the purchase order by inputting the quantity and unit price of the bit coin desired to be purchased, the transaction is established through the sales order matching the transaction condition, The settlement can be performed through the bit-coin.

Such a bit coin type virtual currency is now becoming popular in the virtual money market. At this time, the core of the virtual money is the algorithm for security maintenance, management and security.

Accordingly, it is a virtual money management system based on a block chain. It can issue a public key and a symmetric key separately to provide quick verification and differentiated encryption algorithms. There is a need to develop a virtual money management system.

1 is a conceptual diagram showing a schematic configuration of a system 10 of the present invention.

Referring to FIG. 1, the virtual money management system 10 having enhanced security of the present invention comprises a network server 20 and a user 30 participating in the virtual money management system 10.

First, the network server 20 performs a role of mining virtual money, that is, generating virtual money. For convenience of use, the transaction server, that is, a block including transaction information for which the virtualization transaction is traded, And stores the linked block chain separately.

In addition, the network server 20 can use the protocol of its own for simplifying the old transaction record, that is, the transaction information for the old transaction, and between the users 30 on the network or between the server 30 and the user 30 To reduce traffic, and to enable safe transactions.

The network server 20 may also serve as a coin exchange. The network server 20 encrypts the virtual money wallet consisting of the public key and the private key without providing the private key and transmits the encryption key to the network server 20 Thereby preventing leakage to the outside.

The user 30 of the present invention is a participant participating in the virtual money management system 10 of the present invention, and may be referred to as an owner of a virtual currency, and is a subject of virtual currency transactions, that is, a gift. The user 30 can exchange the virtual money from the network server 20, and additionally stores the transaction history information generated in accordance with the virtual money transaction, and at the same time, . At this time, the node verification can be performed by all the users 30, but preferably only the user 30 having the node including all the blocks generated from the system 10 can participate in the node verification.

2 is a block diagram showing the basic configuration of the system 10 of the present invention.

2, the virtualization management system 10 having enhanced security of the present invention basically includes a virtual money mining module 100, a wallet creation module 200, a currency exchange processing module 300, a block chain management Module 400 as shown in FIG.

First, the virtual money mining module 100 is a process of mining virtual money through a program installed in the network server 20, and mining plays a key role in explaining virtual money.

Digging is usually a way to get a new virtual currency. The process of providing virtual money to a computer that finds it first by competing with a computer (terminal) constituting the virtual money network server 20 to find an operation value satisfying a specific condition is called mining. However, this mining is not only a method of acquiring a simple virtual currency but also a role of authenticating a transaction of a virtual currency.

Since the virtual currency has a starting point that is not related to the government, the law, the central bank, etc., it is necessary to determine whether the transaction between the user A 30 and the user B 30 is a normal transaction or a false transaction by hacking, It is an important matter related to the grounds of existence of

Virtual currency is solved by noting everyone around it that there was a transaction between A and B. By encrypting and transmitting the transaction contents to all terminals (computers or servers) connected horizontally to each other on the network, all of them allow the transaction to be acknowledged.

It also orders the terminals to block them into one block by encrypting the transactions (block chain). The number of terminals participating in this cryptographic operation is also very easy to understand because of the mining.

The wallet creation module 200 creates a virtual money wallet to be given to the user 30 and gives the generated virtual wallet to the user 30. For this purpose, the wallet creation module 210 and the wallet application 220 ).

The wallet creation unit 210 functions to create a virtual money wallet having a wallet address of 30 to 40 digits based on the timestep and a code-based formula, Creates a virtual wallet with a 38-digit wallet address. These virtual money wallets are responsible for the storage and transmission of virtual currency, which is addressed. Therefore, transmitting virtual money to a specific wallet address means that virtual money is transmitted to the virtual wallet corresponding to the wallet address. Preferably, in the present invention, the wallet address is added to the basic wallet address 810 composed of 20 to 30 digits (preferably 25 digits) and to the end of the basic wallet address 810, And a verifying wallet address 820 composed of 15 digits (preferably 13 digits) of codes, which will be described later.

Accordingly, each virtual money wallet must be assigned to the user 30, which can be implemented by the wallet portion 220 of the wallet creation module 200. The wallet attaching / detaching 220 provides each virtual wallet to the user 30, and this enables the user to associate the wallet address corresponding to the virtual wallet with the individual user 30, .

At this time, instead of the mining method, the already-mined virtual currency can be exchanged through the exchange from the first currency (for example, the Korean currency unit), that is, the first currency can exchange the virtual currency For this, the exchange processing module 300 is used. The exchange processing module 300 includes a purchase request unit 310, a currency exchange guide unit 320, and a currency exchange processor 330.

The purchase requester 310 receives the quantity information of the virtual money to be purchased from the user 30 and transmits the quantity information to the network server 20. At this time, Lt; / RTI > This means that the user 30 receives the quantity information, which is the number of the virtual currency to be purchased, that is, the number of the virtual currency to be exchanged, from the user 30 and transmits it to the network server 20, To the server 20, that is, the exchange server.

The exchange guide unit 320 grasps the quantity information of the bit coin to be exchanged and input from the user 30 from the network server 20 (exchange server) and transmits the exchange amount corresponding to the quantity information to the first money And informs the user 30 of the calculated result. If the virtual currency and the first virtual currency are exchanged for Korean won, if the exchange rate at that time is 200,000 won per virtual currency, if the user 30 requests the exchange of the five virtual currencies If you do, it will tell you that you need 1 million won. In this case, a separate exchange fee may be added to the exchange fee, which is the same as the exchange fee of the bank, so a separate explanation will be omitted.

The exchange processor 330 receives the exchange money from the user 30 and transfers the virtual money corresponding to the exchange money to the virtual money wallet of the user 30. This is implemented by transferring a corresponding number of virtual currencies corresponding to the purse address corresponding to the virtual money purse of the user 30. Since the transfer processing of the virtual currency is the same as a kind of virtual currency transaction, Preferably, transaction transaction information is generated. This is similar to the transaction content encryption and propagation described in the virtual money mining module 100 described above.

Finally, the block chain management module 400 is implemented for managing transaction history information generated by the virtual money mining module 100, the currency exchange processing module 300, or the like, that is, transaction transaction information, Block and a block chain in which a plurality of blocks are connected to each other based on the chain, and propagates the block chain to the user 30 registered in the virtual money management system 10 of the present invention.

At this time, the transaction transaction information is transaction information including the transaction history information, and the transaction transaction information is accumulated in the form of an encrypted block. In addition, when a plurality of such blocks are stacked and interconnected, a block chain is formed, which will be described with reference to the related block chain configuration, and thus a detailed description will be omitted.

FIG. 3 is a block diagram showing a detailed configuration of the system 10 of the present invention, and FIG. 4 is a conceptual diagram showing a configuration related to a wallet address structure and a QR code 900 scan of the present invention.

3 and 4, detailed and additional configurations that may be included in the virtual money management system 10 of the present invention will be described.

First, the transaction process of the general users 30 except for the exchange of money (the transaction between the virtual currency and the first currency through the exchange server) and the mining process, that is, the process of providing the virtual money between the users 30, will be described.

The virtual money management system 10 of the present invention may further include a transaction processing module 500. The transaction processing module 500 realizes a virtual money gift between the users 30, An address verifying unit 520, a donation processing unit 530, and a transaction history generating unit 550.

The donation request unit 510 receives from the user 30 the quantity information for which the user 30 wishes to donate to the virtual currency having the member information and the block chain and the quantity information of the purse address And the like. At this time, the user 30 (presenter) who performs the bestowal and the user 30 (voucher) who receives the gift are all the persons who own the virtual money wallet in the virtual money management system 10 of the present invention, Must enter the gift request information including the quantity information of the virtual currency to be donated to the water purifier and the purse address of the corresponding water purifier.

The address verifying unit 520 verifies the purse address of the entered voucher, and verifies whether a correct wallet address for the voucher is inputted from the presenter. At this time, separate information on the voucher is inputted from the presenter It is also possible to match the name of the veteran and the address of wallet by matching the address with the address of the entered voucher purse.

Hereinafter, the purse address verification process will be described in more detail. The purse address generation unit 210 receives a basic purse address 810 of 30 to 40 digits, preferably 38 digits, (820). ≪ / RTI >

To this end, the wallet generator 210 of the wallet generator 210 includes a base address generating part 211 for generating a basic wallet address 810 having 20 to 30 digits, preferably 25 digits, , A verifying address creation part (212) that completes the purse address by creating a verifying purse address (820) which is added to the end of the basic purse address (810) and is composed of 10 to 15 digits, preferably 13 digits code This can be confirmed through the configuration of FIG.

At this time, the default wallet address 810 may be referred to as a public key, and the verification wallet address 820 may be referred to as a private key, and both the public key and the private key are encrypted codes. Therefore, the address verification unit 520 is required not only to decrypt the encrypted code but also to encrypt the private key. Accordingly, the address verifying unit 520 of the present invention includes a decoding processing part 213 and a verification processing part 214 to perform address verification according to decoding.

The decryption processing part 213 performs encryption processing on the inputted purse address, in particular decryption processing on the verification wallet address 820, which is a private key. At this time, the decryption processing method is applied to the purse creation module 200 And the decrypted wallet address generated in the encrypted code form may be decrypted according to the encrypted wallet address generation method of the included wallet generation unit 210. [

In addition, the verification processing part 214 determines the decryption value for the decryption processing part 213 and completes the verification processing. What is important at this time is the decryption processing for the private key, that is, the verification wallet address 820. [ At this time, if the decryption processing value for verifying purse address 820 satisfies [1001] through the verification processing part 214, it is determined that the private key corresponding to the decryption processing is input correctly, and the verification processing is completed and the transaction continues .

Upon finishing the verification by the address verification unit 520, the donation processing unit 530 donates virtual money equivalent to the quantity information input by the presenter to the purse address of the water purifier. Accordingly, the virtual currency of the presenter's virtual currency wallet is subtracted from the virtual currency of the corresponding quantity information, and the virtual currency is paid to the virtual currency wallet possessed by the voucher, thereby completing the gift for the virtual currency. At this time, since it can be used not only for a simple gift but also for the goods transaction, the virtual money is donated from the presenter to the voucher, so that the voucher can provide the presenter with goods corresponding to the value of the corresponding virtual currency. Therefore, it is possible to trade goods based on virtual money.

Thereafter, the transaction history generating unit 550 generates the transaction history information about the awarded virtual currency. At this time, the transaction history information generation and management is performed according to the configuration of the block chain management module 400 described above. Therefore, the transaction transaction information for the virtual money that has been awarded is generated, and the block transaction is managed and blocked by the block chain management module 400.

Further, in the transaction between the general users 30 using the virtual money and the virtual money donation, it is inconvenient that the presenter should know the purse address of the water purifier. In addition, these wallet addresses are encrypted and may be more uncomfortable to input. Therefore, in order to solve such a problem, the address of the wallet may be used in conjunction with the QR code 900.

The wallet creation module 200 may further include a QR code generation unit 230 for generating a QR code 900 including the wallet address, A QR code 900 including an encrypted wallet address is generated to enable connection to the wallet address or input of a wallet address through a QR code 900 scanning and furthermore a virtual wallet Lt; / RTI >

In addition, the transaction processing module 500 may further include a voucher setting unit 540 to be interlocked with the QR code 900. At this time, the voucher setting unit 540 sets the voucher setting unit 540 by the user 30 The purse address corresponding to the QR code 900 is set as a voucher according to the QR code 900 scan. Accordingly, when the user 30 scans the QR code 900 of the water purifier, the purse address included in the QR code 900 is automatically recognized as a voucher, thereby eliminating the inconvenience of inputting a separate purse address.

Therefore, when the donor is set by recognizing the QR code 900 as described above, the donation request unit 510 not only receives the membership information input from the user 30 (the donor) and the quantity information of the virtual money having the block chain, The purse address of the water purifier recognized through the QR code 900 scan and the membership information of the water purifier. Accordingly, the donation request unit 510 generates donation request information including the quantity information input from the user 30 (the donor), the wallet address of the scanned donor, and the membership information of the donor.

In addition, in the present invention, the block chain management module 400 manages the transaction transaction information and the blocks in which the information is accumulated, and further, a block chain in which the blocks are linked to each other. The management module 400 basically includes a block generator 410, a size determining unit 420, a chain forming unit 430, and a copy propagating unit 440.

The block generation unit 410 generates the corresponding transaction transaction information as one block as the transaction history information is generated. The transaction history information may include a plurality of transaction transaction information The transaction information for transaction is bundled into one block and encrypted.

The size specification unit 420 designates the size of the block. In this case, since the size of the block is not specified, the size specification unit 420 can support a dynamic block size, and a transaction for transaction The number of information can change dynamically.

The chain forming unit 430 forms a block chain by connecting the plurality of generated blocks. In addition, a plurality of blocks are connected to each other, and additional encryption may be performed in forming a block chain .

The copy propagation unit 440 transmits a block chain including a plurality of the blocks to a node. Here, a node is a special user 30 that is not a general user 30, (Sum of computation power of cpu or graphics card), and performs recording and writing of transfer records (transaction transaction information) of virtual currency between general wallets in a block chain. Accordingly, the node is a subject directly performing verification and encryption of the transaction of the virtual currency. In return, the virtual money management system 10 of the present invention may assign a certain virtual currency to the nodes, Or deducted from

Accordingly, the virtual money management system 10 may include a group classification module 600 for classifying the user 30 into a verifier group and a participant group, . Here, the verifier group means a special user 30 performing a role of a node, and the participant group means a general user 30 not performing the role of the node.

In this case, the user 30, which preferably serves as a node, must have all the blocks up to the point of participating in the node role, that is, all the blocks including the transaction history information generated up to that point. Accordingly, the group classification module 600 may include a block identification unit 610 for identifying a block owned by the user 30, and the transaction history information on the transactions performed during the process may be transmitted to the user 30 You can see if you have everything. Thereafter, the verifier 30 classifies the user 30 who is confirmed to be in possession of all the blocks by the block identification unit 610 among the users 30 who want to participate in the node role by the verifier group classification unit 620 The participant group classifier 630 classifies the user 30 who does not intend to participate in the verifier group or who does not have all the blocks in the verifier group, will be.

The special user 30, that is, the node, records transaction records (transaction transaction information) of virtual currency in a block chain, and verifies and encrypts them. At this time, transaction information for transaction, that is, The block-chain management module 400 further includes a verification unit 450. The verification-

The verification execution unit 450 performs a function of verifying the transaction history information from the verifier group. It can be said that the block chain management is complete only when verification of the verifier group, that is, the node is completed, Therefore, this verification is essential for all transactions and mining.

More specifically, when a wallet user 30 requests the coin transmission to the network, the neighboring nodes sequentially receive the transmission request and write it to the block chain that this is the correct transmission request. This record must be made n times (n is at least three times) to ensure that the transfer is complete and that the ownership of the virtual currency is fully transferred from the system 10.

In addition, the virtual money management system 10 of the present invention can exchange money between the first currency and the virtual currency through the exchange processing module 300, wherein the exchange is based on the exchange rate. At this time, the exchange rate is controlled by the market economy according to the virtual currency transaction between the users 30, but it is also possible to adjust the exchange rate separately on the system 10.

For this purpose, the system may further include a currency control module 700 for differentiating the exchange rate between the first currency and the virtual currency. In this case, the differential adjustment of the exchange rate may include adjusting the exchange rate between the first currency and the virtual currency If the exchange rate is too low or high, it can be adjusted to stabilize the exchange rate, or it is also possible to adjust the exchange rate only for the specific user 30.

More preferably, the exchange between the node and the non-node user 30, i.e., the verifier group and the participant group, may be adjusted. 10) is high.

Accordingly, the exchange rate adjustment module 700 not only distributes a separate virtual currency to the verifier group by differentiating the exchange rate for the verifier group and the participant group, Configuration can be provided. For this, the exchange rate control module 700 further includes a reference rate determination unit 710, a group rate addition unit 720, an additional rate addition unit 730, and a currency conversion unit 740.

The first currency is one of a variety of currencies, such as a circle, yen, euro, dollar, and the like, and the currency of the corresponding currency Which is a basic exchange rate established by the market economy between the virtual currency and the virtual currency.

The group rate addition / non-provision rate assignment unit 720 functions to assign a group rate to the user 30 belonging to the verifier group, and gives a group rate to the user 30, i.e., the node belonging to the verifier group And to provide a separate reward for performing the node role. At this time, the group rate may be a commission cut or a direct exchange rate cut.

The additional discount rate provision section 730 performs a function of granting an additional discount rate based on the verification characteristics of each of the users 30 belonging to the verifier group. In this case, (30), that is, each node includes a verification amount of transaction history information and transaction transaction information, a verification period in which verification is performed, a verification count, and verification accuracy. Therefore, the verification characteristic can be changed according to the user 30 (i.e., the node) within the verifier group according to the period belonging to the verifier group and the number and accuracy of the verification performed within the verifier group.

The verification period identification part 731 included for this purpose performs a function of determining a verification period of the node belonging to the verifier group and setting a period weight. The verification period identification part 731 includes a transaction history information, transaction transaction information, Or a longer period of time for which the verification of the block chain is performed, a higher period weight is set. There is no limitation on the value of the period weight, and may be set within a range of 0 to 1, or within a range of 0 to 100.

In addition, the supplementary rate provision part 730 may include a verification amount checking part 732. The verification amount checking part 732 checks whether the node belonging to the verifier group has transaction history information, transaction transaction information, Or the block chain is verified and the verification weight weight is set. At this time, there is no limitation on the value of the verification amount weight, and the higher the verification amount, that is, the higher the verification amount, the higher the verification amount weight is set. At this time, the verification amount weight may be set within a range of 0 to 1, or may be set within a range of 0 to 100. In this case, the verification amount is different from the verification number, and the more information included in the block (block chain), the larger the verification amount. That is, if one block is verified, the verification number is 1, but the verification amount may be changed according to the number of information included in the corresponding block. That is, if one block includes only one transaction history information, the verification number and the verification amount are the same, but if one block includes five transaction details information, the verification number is once, and the verification amount is five times.

The verification number determination part 733 determines the number of verifications in which the node (user 30) belonging to the verifier group verifies the transaction history information, transaction transaction information, or block or block chain, and outputs the verification number weight value The higher the number of verification times, that is, the more times the verification is performed, the higher the verification number weight is set. In this case, the verification frequency weight may be set within a range of 0 to 1, or may be set within a range of 0 to 100.

The accuracy determination part 734 determines the accuracy of the verification of the node belonging to the verifier group and sets the accuracy weight. As the node performs the verification directly to determine whether the verification is completed, I think it is possible. Therefore, if the verification performed by the specific node is perfect, that is, if the accuracy is 100, the accuracy weight may be 1 (the weight of the weight is 1) or 100 (the weight of the weight is 100) If the accuracy is 50%, the accuracy weight may be set at 0.5 or 50.

The additional rate calculation part has the above-described period weight value, the verification amount weight value and the verification weight value calculated through the above-described verification period identification part 731, verification amount confirmation part 732, verification number confirmation part 733 and accuracy verification part 734, The additional discount rate is calculated based on the verification frequency weight and the accuracy weight. In this case, the additional discount rate is preferably calculated by the following equation (1).

Equation 1,

는 상기 사용자(30)에 대해 산출된 추가우대율,

는 상기 사용자(30)의 검증횟수가중치,

는 상기 사용자(30)의 기간가중치,

는 상기 사용자(30)의 검증량가중치,

는 상기 사용자(30)의 정확성가중치를 의미한다.here,

The additional rate calculated for the user 30,

The number of verification times of the user 30,

The duration weight of the user 30,

The verification weight weight of the user 30,

Means the accuracy weight of the user 30.

Therefore, not only the verification weight weight and the verification weight weight with respect to the period weight can be obtained through the equation (1), but also the equation established through the relationship between the period weight and the verification weight weight is multiplied by the accuracy weight, , The accuracy rate is high, the verification amount weight is large, and the higher the verification number weight is, the higher the additional rate can be obtained.

For example, if the verification frequency weight is 15, the period weight is 60, the verification weight is 24, and the accuracy weight is 1 (100%), all the values are substituted, the additional rate is 46.8 (%). Since the assumption is that the preferential rate is derived as a percentage, 46.8% of the preferential rates are derived.

The exchange rate calculating unit 740 calculates the final exchange rate by reflecting the group rate and the additional rate on the reference exchange rate. The exchange rate calculating unit 740 is a basic reward The group discount rate, and the rate of additional discount calculated according to the number of times, the period, the accuracy, and the verification amount of the individual nodes performing the verification, thereby calculating the final exchange rate for the individual user 30. In this case, the final exchange rate will differ mainly for the verifier group. In case of the participant group, the base exchange rate may be the final exchange rate. If the group rate is reflected in the participant group, This can be the final exchange rate.

As described above, the configuration and operation of the virtual money management system 10 with enhanced security according to the present invention are described in the above description and drawings. However, the present invention is not limited to the above description and drawings. And it is to be understood that various changes and modifications may be made without departing from the spirit of the invention.
