Description

Cryptocurrency Electronic Wallet System {CRYPTO CURRENCY ELECTRONIC WALLET SYSTEM}

The present invention relates to a cryptocurrency electronic wallet system.

In general, cryptocurrency electronic wallets store cryptographic keys and can access the blockchain through proof of identity using the stored cryptographic key (or private key). In addition, such a cryptocurrency electronic wallet allows access to the blockchain to send or receive cryptocurrencies between users and to conduct transactions.

In addition, a cryptocurrency electronic wallet has a wallet address generated when the wallet is created, and the wallet address can be used when transferring or trading cryptocurrencies with other users.

However, the wallet address of cryptocurrency, for example, the electronic wallet address of Bitcoin is '1BKk8hsRkHp1htXqkHayal8d2N4kWxgwz', and in the case of Ethereum '0xdc5d9d15740d88451B0f81fe7f2aC34117Af9D8f', the user is very long and very complicated, and the user is very difficult to use. When using a wallet, it is inconvenient to input one by one.

In order to solve this problem, in the current electronic wallet system, the wallet address is converted into a QR code, or copied and used by the user to memorize or use it more easily.

However, as one of the hacking cases of electronic wallets, when copying and pasting a wallet address recently, a cryptocurrency was sent to an address of an unrelated person due to being changed to a hacker's wallet address.

In the case of using the QR code conversion, since the user does not enter the wallet address as it is, it can be sufficiently hacked in the above manner.

For example, if user A sends an identifier of 'apple' to verify that the identifier currently entered by him is valid, then he compares 'apple' with the identifiers that other users have requested to verify, The identifiers that were used as wallet addresses in 'n' can be compared with 'apple', respectively, to validate that 'apple' can be used without duplicate history.

On the other hand, the identifier validation unit 122 may provide any identifiers available to the first electronic wallet 110 when the validation is not validated more than a predetermined number of times for the various identifiers desired by the user. One of these can be selected by the user or a new identifier can be entered again.

For example, when the user has not validated the identification character more than three times, that is, when it is determined to be unavailable, the first electronic wallet 110 may present the present as 'apple1', 'apple2', or 'apple3'. It is possible to recommend a candidate for use of the identification character, and at this time, the user may select a desired identification character from among the user, or by focusing on a recommended identification character such as 'apple4' and receiving the changed new identification character again and processing it.

The identification character verification result transmission unit 123 may transmit the verification result through the identification character validity verification unit 112 to the first electronic wallet 110. Here, as the verification result, the requested identifier may be configured to be easily recognized by the user in a manner that is valid or invalid as the wallet address.

The address information matching setting unit 124 may set matching between the wallet address and the identification character according to the verification result of the identification character validity verification unit 122.

The wallet address conversion transmission unit 125 receives a transfer and transaction execution signal of a cryptocurrency from the first electronic wallet 110, converts it into a corresponding wallet address matched with the received identification character, and transmits it to the first electronic wallet. Can be. This transfer and transaction execution signal allows the first server 120 to know that the current user is sending or attempting a transaction with another user, while the correct wallet address matches the identifier sent with the signal. To provide the first electronic wallet 110 (where the electronic wallet of the user who sends the cryptocurrency).

The first cryptocurrency electronic wallet system 100 according to the first embodiment described above allows a specific identification character desired by a user to replace the wallet address, so that even if a complicated long wallet is not used, the transfer and transaction of the cryptocurrency It is possible to use, and even without using the copy and paste information on the wallet address by allowing the user to directly enter a relatively simple configured identification characters, security from hacking and the like can be improved.
