Method and system for bank storage of digital currency

Abstract

The present invention provides a method and system for bank storage using a digital currency chip card. The method includes: after the accepting terminal device establishes a communication connection with the digital currency chip card, receives deposit information input by an external operation, and sends the deposit information to To the digital currency system of a commercial bank, the deposit information includes deposit account information, digital currency chip card information, and digital currency equivalent to the deposit amount; the commercial bank digital currency system sends a change attribute to the central bank digital currency system after receiving the deposit information. The owner's request; after the central bank digital currency system receives the request to change the owner, it will change the owner of the digital currency to a commercial bank and change the amount of the deposit account. Through the bank storage method and system using digital currency chip cards provided by the present invention, the purpose of fast and convenient storage of digital currency can be effectively achieved.

Description

technical field [0001] The invention relates to the technical field of computer network and computer software, in particular to a method and system for bank storage of digital currency. Background technique [0002] Digital currency is a currency that converts cash values ​​into a series of electronically encrypted serial numbers. The security of the currency itself depends on cryptographic algorithms for protection. In terms of cryptographic algorithms, the security of digital currency systems involves symmetric ciphers, asymmetric ciphers, message digest algorithms, and identity-based cryptographic systems. In terms of system implementation, the overall security of cryptographic systems, the selection of cryptographic algorithms, and cryptographic algorithms must be deeply considered. The implementation of algorithms, the design of interactive protocols, the compatibility of international and domestic standards, etc., ensure the security of digital currency transactions. ...

Problems solved by technology

[0010] 2. Non-repeatable spending: digital currency can only be used once, and repeated spending can be easily checked;

[0011] 3. Controllable anonymity: Banks and merchants cannot track the use of digital currency even if they collude with each other. It is required that the system cannot link the purchase behavior of users of electronic cash together, thereby concealing the purchase history of digital currency users. However, the issuer of digital currency Use of digital currency can be tracked;

[0012] 4. Unforgeability: Users cannot forge fake digital currency;

[0019] Deposit certificates or passbooks need to be manually deposited by bank staff at the bank counter, which cannot be done by themselves. This will consume time and energy for depositors, and it is easy to lose the passbook. Although bank cards can be deposited at the counter or ATM of any branch of a commercial bank, but This method is limited by the geographical distribution of commercial bank outlets, so the above two methods are inconvenient
