Description

암호화화폐 통합 거래시스템 및 그 방법{System for exchanging integrated crypto coin and the method thereof}System for exchanging integrated crypto coin and the method

본 발명은 암호화화폐 통합 거래시스템에 관한 것으로, 더욱 상세하게는 구매자단말기와 판매자단말기 간의 암호화화폐 거래에 있어서, 구매자단말기와 판매자단말기가 회원가입한 결제서버를 통해 판매자단말기에 의해 암호화된 거래정보를 다시 한번 암호화함으로써 암호화화폐 시스템별로 각기 다른 암호화화폐 전송방법을 통합할 수 있고, 암호화화폐 지갑 분실 및 불법 암호화 화폐 유통에 대한 보안성을 높일 수 있는 암호화화폐 통합 거래시스템에 관한 것이다.The present invention relates to a cryptocurrency integrated transaction system, and more particularly, in a cryptocurrency transaction between a buyer terminal and a seller terminal, the transaction information encrypted by the seller terminal through a payment server to which the buyer terminal and the seller terminal are registered. By encrypting once again, it is possible to integrate different cryptocurrency transfer methods for each cryptocurrency system, and to relate to a cryptocurrency integrated transaction system that can enhance the security of cryptocurrency wallet loss and illegal cryptocurrency distribution.

최근에는 인터넷 등을 활용한 암호화화폐가 등장하여 개인간 송금 서비스 등에 활용되고 있다. 화폐로 사용되는 암호화화폐와 같은 분산형 전자 전송 시스템은 각각의 전송을 체크 및 인증(validate)하는 중앙조직(central organism)을 가질 필요성을 없애고, 그 비용 소모를 회피하기 위해 생성된다. 중앙 전자 전송 시스템들은 상거래 시 사용자에 의해 행해진 전송 요청을 인증하기 위해 사용자의 중앙 조직에 대한 식별 및 인증(authentication)의 조합에 의존한다.Recently, cryptocurrency using the Internet has emerged and is being used for personal money transfer services. Distributed electronic transmission systems, such as cryptocurrencies used as currency, are created to eliminate the need to have a central organism that checks and validates each transmission, and avoids the cost. Central electronic transmission systems rely on a combination of identification and authentication for a user's central organization to authenticate transmission requests made by the user in commerce.

즉, 암호화화폐를 이용한 지불 결제시스템은 P2P(peer to peer) 방식으로, 여러 이용자의 컴퓨터에 분산돼 있다. 암호화화폐 용 계좌는 지갑이라고 부른다. 이지갑은 별도 프로그램이나 웹사이트를 써서 만들어진다. 지갑을 만들면 인터넷상에서 한 쌍의 암호키가 생성된다. 그 중 암호키 하나는 본인만 확인할 수 있는 개인 키로 단말기를 통해 가지게 된다. 나머지 암호키 하나는 가상 코인을 사용하는 모두에게 공개돼 있는 암호키이다. 예를 들어 비트코인 사용자가 물건을 사기 위해 개인암호키로 전자서명을 했다고 하면 이때 비트코인을 사용하는 다른 사용자들은 공개 암호키를 통해 전자서명을 한 사람이 암호키의 주인이 맞는지를 인증할 수 있다.In other words, a payment settlement system using cryptocurrency is distributed to computers of multiple users in a peer-to-peer manner. Cryptocurrency accounts are called wallets. This wallet is created using a separate program or website. Creating a wallet creates a pair of cryptographic keys on the Internet. One of the encryption keys is a private key that only the user can verify through the terminal. The other encryption key is an encryption key that is open to everyone who uses virtual coins. For example, if a Bitcoin user signs an electronic signature with a personal cryptographic key to buy something, other users of Bitcoin can use the public cryptographic key to verify that the person who signed the digital signature is the owner of the cryptographic key. .

이러한 전자서명과 인증 과정이 계속 반복되면서 상거래가 이뤄지는 체계이다. 하지만, 현재 서비스되고 있는 이러한 암호화화폐 거래시스템들은 시스템별로블록 타입이 다양하고, API 및 Connection정보도 각각 달라 서로 다른 시스템끼리 암호화화폐 거래가 이루어질 경우 블록 이동에 대한 해킹 및 보안성에 문제가 있었다.The electronic signature and certification process is repeated over and over, and commerce takes place. However, these cryptocurrency trading systems that are currently being serviced have various block types for each system, and API and connection information are different, so there is a problem in hacking and security of block movement when different systems make cryptocurrency transactions between different systems.
