Recently, Internet virtual currency has been widely spoken. A virtual currency is a digital currency or electronic money that is used in electronic form in a virtual space connected to a network without a real object such as a bill or a coin. According to the definitions of the European Central Bank (ECB), the US Treasury and the European Banking Supervisory Board, cryptocurrency is a digital currency that is not controlled by the government and is issued and managed by the developer and used only in certain virtual communities. According to this definition, most cryptocurrencies are digital and virtual.

Bitcoin is an online cryptocurrency built on blockchain technology. It is designed to allow financial transactions such as remittances freely between individuals on a global basis without a central bank. It is virtually impossible to hack because the transaction ledger is distributed and stored on servers of various users in the global scope based on blockchain technology. Use SHA-256 based password hash function.

Bitcoin is not a currency used in real life, but a cryptocurrency used in online trading.It is a method of operation that is paid in return for solving a very difficult mathematical problem presented by a computer.It is open under the MIT license. It was released as a source, and a variety of altcoins such as Ethereum, Ethereum Classic, Ripple, Litecoin, Eicoin, Dash, Monero, JetCash and Quantum were created. Bitcoin is a kind of key currency among many altcoins.

In general, a Bitcoin account is called an 'e-wallet', and each e-wallet is given a unique number of about 30 characters including a combination of numbers, lowercase letters and uppercase letters in English, and public keys for personal authentication and currency transactions. Transaction is performed based on the cryptographic system of the Public Key Interface. The public key infrastructure of the Internet cryptocurrency consists of a public key for the purpose of trading and a private key dependent on the public key. The public key corresponds to an account number of the Internet cryptocurrency.

Conventionally, points are given as bonuses to members according to transaction or sales of goods through points earning companies such as Internet shopping malls, banks, card companies, etc., or by the use of services, and members exchange points for cyber money.

Referring to FIG. 6, the dealing coin brokering module 310 processes authentication of selling the dealing coin to the A member who wants to sell the dealing coin (S521). The dealing coin brokering module 310 determines whether the A member authentication is successful (S522), and if the authentication is successful, the dealing coin decryption information is transmitted to the B member terminal that purchased the dealing coin, and then in the "transaction in progress" state. Dealing coin transaction request information of the transaction is updated and stored in the "complete transaction" state (S523, S524).

The second electronic wallet module mounted on the B member terminal accesses the dealing coin generation module 210 when the decryption information for the dealing coin information owned by the member A is input from the dealing coin intermediation module 310 to deal with the owning member A. Dealing coin owner change request information including coin information and dealing coin decryption information is transmitted. The second electronic wallet module mounted on the member B receives the dealing coin information and the dealing coin encryption information owned by the dealing coin generating module 210 and stores it in the main account.

Now, a dealing coin remittance process will be described with reference to FIGS. 7 and 8. In the following description, it is assumed that the first electronic wallet module receives the dealing coin, and the second electronic wallet module transfers the dealing coin. In addition, it is assumed that the A member terminal is a terminal on which the first electronic wallet module is mounted, and the B member terminal is a terminal on which the second electronic wallet module is mounted.

The dealing coin intermediary module 310 receives the dealing coin remittance request information transmitted from the first electronic wallet module and stores it in the database in a "transfer wait" state, and transmits the dealing coin remittance request confirmation information to the second electronic wallet module. (S711, S712). Dealing coin remittance request confirmation information may be, for example, information for confirming whether the remitter A is correct to request the remitting coins.

The dealing coin intermediary module 310 receives the acknowledgment and response information from the second electronic wallet module (S713) and checks whether the remittance request is correct (S714). If the remittance request is not met, the information stored in the database in the state of "pending remittance" is deleted. On the other hand, if the transfer request is correct as a result of the check transfers the control button generation control information to the second electronic wallet module (S715). As another example, the dealing coin intermediary module 310 receives the information regarding the dealing coin to be remitted from the second electronic wallet module when the transfer request is correct, and transmits it to the first electronic wallet module (S716).

The first electronic wallet module mounted on the A member terminal receives the dealing coin information and stores it in the sub account. For example, the first electronic wallet module may be implemented to automatically store the dealing coin information in a sub account if the other person owns it.

Referring to FIG. 8, the dealing coin brokering module 310 processes authentication of the dealing coin transfer to the B member (second electronic wallet module) who wishes to transfer the dealing coin (S717). The dealing coin intermediary module 310 determines whether the B member authentication is successful (S718), and if the authentication fails as a result of the determination, deletes the information stored in the database in the "waiting for remittance" state (S719). On the other hand, if the determination is successful, the dealing coin decryption information is transmitted to the A member terminal (S720).

The first electronic wallet module mounted on the A member terminal accesses the dealing coin generation module 210 when the decryption information of the dealing coin information owned by the B member is input from the dealing coin intermediation module 310 to deal with the belonging B member. After transmitting the information for changing the owner of the dealing coin, including the coin information and the dealing coin decryption information, receive the owning dealing coin information and dealing coin encryption information from the dealing coin generation module 210 and stores it in the main account (S721). ). The dealing coin intermediary module 310 stores the remittance result information in the database (S722).

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes may be made without departing from the spirit of the present invention. This will be apparent to those of ordinary skill in the art. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
