Description
The present invention relates to a transaction method using electronic money, and more particularly, to a transaction method using an electronic money, in which an electronic money user can directly exchange real money, prevent an error that may occur during a block chain generation process, The present invention relates to an electronic money transaction system and method for enhancing the security of transactions.
Electronic commerce services are spreading as network technology such as IT technology and the Internet develops. E-commerce is generally defined as business to business (B2B), business to customer (B2C), customer to customer (C2C) Business to Government (B2G), which includes a series of actions such as purchasing, shipping, marketing, and providing services, as well as moving money through a wired or wirelessly connected network system. .
With regard to such electronic commerce, a payment method using virtual electronic money has recently become an object of interest. A typical example of electronic money is a bit coin. Bitcoin is electronic money created by Satoshi Nakamoto in 2009. It is based on a peer-to-peer network (P2P network) and deals with transactions based on public key cryptography. The bit coin is stored in the form of a wallet file. Each wallet is given a public address and a private key corresponding to the password, and purchases are possible based on the public address. The transaction history of electronic money is generated and verified in a P2P network, and all the generated blocks are stored in the verification process, forming a block chain through connection with other blocks.
1 is a diagram illustrating a structure in which electronic money is traded through a block chain. Referring to FIG. 1, a process of trading electronic money between users is as follows. Each user generates a public key and a private key. Encrypted data using the public key can be decrypted using the corresponding private key. Conversely, data encrypted using the private key can be decrypted using the corresponding public key. It can be decoded only by using it. In order for the user B to transmit the electronic money to the user C, the user B hashes the transaction details of the electronic money using the public key of the user C. Once the hashing is done, the transaction history can not be restored. User B hashes transaction details using user C's public key and signs it using his / her private key. The signed result is delivered to user C. The data received by the user C can be decrypted using his / her private key since the transaction is encrypted using his / her public key. The transaction of the electronic money is completed by decrypting the encrypted transaction details.
The conventional system for trading using the electronic money forming the block chain can be performed only when the seller who wants to sell the electronic money and the purchaser who wants to purchase the electronic money open the electronic wallet. To this end, a user who wishes to trade electronic money opens an electronic wallet by connecting to a transaction server, and then buys the electronic money by transferring the real money to the exchange. After confirming that the real money has been transferred, the exchange places the electronic money in the electronic wallet of the user who purchased the electronic money. When a user intends to sell electronic money, he or she accesses an exchange server to transfer the electronic money, and then purchases the electronic money transferred by the purchaser, thereby transferring the real money to the buyer. That is, the conventional electronic money exchange does not provide a direct exchange of electronic money and real money with a user, but mediates a transaction of electronic money between a seller and a purchaser. On the other hand, in the case of bit coin, which is a representative example of electronic money, one block is generated every about ten minutes. Therefore, since it takes about 10 minutes to verify the next transaction after the previous transaction, using the bit coin as the electronic money in the short-time electronic commerce may cause a problem of hindering the promptness of the transaction.
As an example of transaction using the bit coin, Japanese Patent Application Laid-Open No. 10-2016-0009301 (a settlement agent service of a private key-based electronic money and a method thereof) and Registered Patent Publication No. 10-1628007 , And Patent Registration No. 10-1628009 (a transaction system of digital virtual currency having a block chain between parties).
However, this conventional technology does not provide a direct exchange of electronic money and real money between exchanges and users, and there is a problem that it is difficult to carry out an immediate transaction due to the time required for verifying a block (about 10 minutes). In addition, electronic money such as bit coin is aimed at transparency that can display transaction details included in each block. Accordingly, as shown in FIG. 2, a third party can confirm all transaction details included in each block. In addition, since all the source code of the software including the principle of running the transaction system is disclosed, it is possible to observe all transactions transparently. However, among users who participate in transactions using electronic money, it is a fact that it is difficult to provide security for transaction details to a company or a store who wishes that transaction details through electronic money are not disclosed to the outside.
