Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an offline payment system and a method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an offline payment system and method using bit coin, and more particularly, to an offline payment system using bit coin and a method thereof.

In recent years, virtual coins utilizing the Internet have appeared and are used for inter-personal remittance services.

The bit coin of the virtual coin is used as currency in electronic commerce such as the Internet as it is recognized as a currency in countries such as the UK, Germany, and the United States, and is used as payment means such as cash or credit card in offline commerce. Is increasing.

Distributed electronic transmission systems, such as bit coins that are used in currency, are created to eliminate the need to have a central organism to check and validate each transmission and to avoid costly consumption thereof.

Central electronic transmission systems rely on a combination of identification and authentication for the central organization of the user to authenticate transmission requests made by the user at the time of commerce.

Distributed electronic transmission systems, on the other hand, rely on a combination of identification and disclosure to authenticate a transfer request by a user upon commerce. By doing so, the public can see all the transmissions they publish and check their accuracy.

Accordingly, the payment settlement system using the bit coin is subjected to 6-step authentication at the time of commercial transaction. This certification is made by the computer of the bit coin user, not by the credit card company, the bank, or the payment agency.

That is, the payment system using the bit coin is peer-to-peer (P2P) and is distributed among the users' computers. The Vicco account is called a wallet. This wallet is made using a separate program or website. When you create a wallet, a pair of encryption keys is created on the Internet. One of the keys is a private key that can be identified only by the user. One of the remaining cryptographic keys is a cryptographic key that is open to everyone using bit coins. For example, if a bit coin user signs an electronic signature with a private encryption key to buy something, then other users who use the bit coin can authenticate that the person who signed the electronic signature is the owner of the encryption key through the public encryption key . Such a digital signing and authentication process is a system in which transactions are repeatedly repeated. At this time, 6-step authentication is performed.

However, since the payment system using bit coin requires 6-step authentication at the time of commercial transaction, the distributed network participating in the bit coin transfer authentication at the time of the bit coin transfer between P2P authenticates the transaction, and records the transfer process as 'block chain' , It is difficult to use it as a payment method due to a delay in an offline commercial transaction in which a transaction takes place within about one minute.
