Description

Technical Field

[0001] The present invention relates to the field of blockchain technology, and more specifically, to a blockchain-based authorization code payment method, system, terminal and storage medium. Background Art

[0002] Authorization code payment refers to the authorization code password generated according to the established unified payment rules and verification methods. The password sets the available electronic virtual quota according to the business scenario requirements. In the scenario where payment is required, this password is used to realize the withholding quota for payment. When the specified time or consumption quota is reached, the actual settlement of the relevant bill fees is automatically carried out through the bank system.

[0003] However, existing technologies use http and https protocols to transmit authorization codes, perform access control, and perform signature verification, as well as use traditional databases to store information related to authorization codes. When using authorization codes for payment, authorization codes and personal information may sometimes be leaked, causing unsafe risks in the authorization code limit. Even during the payment data transmission process, data may be intercepted, cracked, and tampered with by a third party, causing system insecurity and economic losses. Authorization verification services rely on limited server resources. Once these servers fail or are attacked, causing service unavailability, all consumer payment operations will be unable to proceed, causing economic losses. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art and provide a blockchain-based authorization code payment method, which can effectively prevent data from being cracked and tampered with during the authorization code payment process, thereby improving the security and reliability of authorization code payment and greatly improving user experience.

[0005] The second object of the present invention is to provide an authorization code payment system based on blockchain.

[0006] A third object of the present invention is to provide an authorization code payment terminal.

[0007] A fourth object of the present invention is to provide a storage medium.

[0008] The first object of the present invention can be achieved by adopting the following technical solutions:

[0009] A blockchain-based authorization code payment method, characterized in that the method comprises:

[0010] Obtain authorization code data to write smart contracts and store the smart contracts in the blockchain;

[0011] When the user logs in and requests the authorization code to be generated, obtain the authorization code data requested by the user and call the smart contract to verify the validity of the authorization code data:

[0012] When the verification request authorization code data is valid, the request authorization code data is encrypted and stored in the blockchain, an authorization code password 1 is generated, and the authorization code password 1 is encrypted and sent to the user end;

[0013] When the verification request authorization code data is invalid, the authorization code application request fails, and the user is notified;

[0014] When the user logs in to request an authorization code payment, obtain the authorization code password 2 requested by the user, encrypt the authorization code password 2 and the user login, and call the smart contract to verify the validity of the authorization code password 2:

[0015] When the second authorization code password is verified to be valid, the authorization code payment is completed and the user is notified; the authorization code amount information and status in the authorization code data are updated, and the record of this payment is stored in the blockchain;

[0016] When the second verification authorization code password is invalid, the current authorization code payment request fails and the user is notified.

[0017] Furthermore, the authorization code data includes the authorization code amount, authorization code usage, user identity information and validity period.

[0018] Furthermore, obtaining authorization code data to write a smart contract and storing the smart contract in the blockchain means:

[0030] The authorization code password 2 and user login information are passed to the smart contract through asymmetric encryption and MD5 encryption signature. The smart contract is called to verify the payment authorization code data and request authorization code data corresponding to the authorization code password 2 according to the verification rules. The payment authorization code data includes the payment authorization code amount, payment authorization code usage, payment user identity information and payment validity period. If the verification rules meet the following conditions, the verification authorization code password 2 is valid:

[0031] (1) The payment authorization code amount is less than or equal to the request authorization code amount;

[0032] (2) The payment authorization code usage item matches the request authorization code usage item;

[0033] (3) The identity information of the payment user matches the identity information of the requesting user;

[0034] (4) The payment validity period is within the request validity period;

[0035] When the second authorization code password is verified to be valid, the authorization code payment is completed and the user is notified; the information and status of the authorization code amount in the authorization code data are updated, and the record of this payment is stored in the blockchain.

[0036] The second object of the present invention can be achieved by adopting the following technical solutions:

[0056] (I) Obtain authorization code data to write a smart contract and store the smart contract in the blockchain. The authorization code data includes the authorization code amount, authorization code usage, user identity information and validity period.

[0057] According to the authorization code data, a smart contract is written and stored in the blockchain. The smart contract is written in solidity language and compiled into a binary file that can be read by EVM, and then deployed to the blockchain for execution; a smart contract deployed on the blockchain will be assigned a contract address, and subsequent calls to the smart contract will use the contract address for calling. Once the smart contract of the present invention is successfully deployed, stored and executed on the blockchain, the smart contract will not be modified by anyone, meeting the 100% trusted mechanism requirements. Subsequent authorization code generation and verification during authorization code payment are achieved by calling this smart contract through the contract address.

The present invention uses the decentralized characteristics of the blockchain to store the request authorization code data in a distributed manner in all nodes of the blockchain network, ensuring that the request authorization code data will not be lost and is available in real time. Finally, the authorization code password 1 is encrypted and signed using md5 and sent to the user end to prevent data tampering.

[0060] 2. When the verification request authorization code data is invalid and the authorization code application request fails, the user end is notified.

[0063] II. The requested authorization code usage item matches the authorization code usage item;

[0064] III. Requesting user identity information matches the user identity information;

[0065] IV. The request is valid within the validity period.

[0066] (III) When the user logs in and requests the authorization code payment, obtain the authorization code password 2 for the user requesting the authorization code payment, pass the authorization code password 2 and the user login information to the smart contract through asymmetric encryption and MD5 encryption signature, and call the smart contract to verify the payment authorization code data corresponding to the authorization code password 2 and the request authorization code data according to the verification rules, where the payment authorization code data includes the payment authorization code amount, the payment authorization code usage, the payment user identity information and the payment validity period; if the verification rules meet the following conditions, the verification authorization code password 2 is valid:
