Description
Technical Field
The present invention relates to the field of account information management technologies, and in particular, to an account information management method, system, and readable storage medium.
Background
When a user registers an electronic wallet in an issuer, the issuer server needs to register a virtual account for the user, and synchronize account information corresponding to the virtual account to a acquirer server and a clearinghouse server. When a user modifies account information, it is also necessary to synchronize the modified account information to the acquirer server and the clearinghouse server. If the user registers the electronic wallet, after the card issuing bank server receives a registration request, a virtual account is established according to the registration request, account information corresponding to the virtual account is stored in a Database (DB), and the user is informed that the virtual account is successfully registered; the card issuing server sends the registration request to a receiving bank server through an HTTPS (Hyper Text Transfer Protocol over Secure Socket Layer, network Protocol); and after receiving the registration request, the acquirer service establishes a virtual account according to the registration request, stores account information corresponding to the virtual account into the DB, and returns a response message to the issuer server to remind the issuer server that the registration request is successfully received. Likewise, the issuer server sends the registration request to the clearinghouse server via HTTPS. The specific process can refer to fig. 1.
If the network fails in the process of sending the response message to the card-issuing bank server by the receiver bank server, the card-issuing bank server considers that the receiver bank server does not successfully receive the registration request, the card-issuing bank server periodically resends the registration request to the receiver bank server, and sends the registration request to the clearing bank server after successfully receiving the response message sent by the receiver bank. Therefore, the card issuing server is responsible for the consistency of the account information among the card issuing server, the acquirer server and the clearing house server, and the card issuing server needs to consider the synchronous situation of the account information of the acquirer server and the clearing house server at the same time. And the user consumes in the virtual account, and the corresponding consumption data is also recorded in the database of the card issuer server, so that the consumption data cannot be synchronized to the clearing house server in real time. At present, after finishing every day, the card issuer server sends consumption data of one day to the clearinghouse server, and the clearinghouse server executes a clearing operation according to the consumption data. It can be seen that at present, the account information (including the consumption data) between the issuer server, the acquirer server, and the clearinghouse server cannot be synchronized in real time, which makes it difficult for the issuer server to maintain consistency with the account information between the acquirer server and the clearinghouse server.

Based on the hardware structure, various embodiments of the account information management method are provided.
Referring to fig. 3, fig. 3 is a flowchart illustrating an account information management method according to a first embodiment of the present invention.
In the present embodiment, an embodiment of an account information management method is provided, and it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here.
In this embodiment, an account information management method is applied to an account information management system, and the account information management method includes:
Step S10, after receiving the registration request for registering the virtual account through the card issuer server, obtaining the account information corresponding to the virtual account, and writing the account information into the card issuer block chain node corresponding to the card issuer server.
In the embodiment of the invention, the acquiring bank server corresponds to the acquiring bank blockchain node, the clearing bank server corresponds to the clearing bank blockchain node, and the card issuing bank server corresponds to the card issuing bank blockchain node. The receiving single-row block chain node, the clearing row block chain node and the issuing row block chain node jointly form a alliance chain. The alliance chain is a block chain system which is composed of mutually trusted organization nodes, connection is established between the nodes, data transmission is carried out in a safe and reliable mode, such as authentication, an IP (Internet Protocol, Protocol for interconnection between networks) white list and the like, and external nodes cannot be added. The node refers to a network node participating in a blockchain network for transaction and data exchange, each independent organization can have one or more transaction nodes, and each transaction node is a combination of a group of physical networks, computers, blockchain application software and databases.
The data signatures represent the identities of the acquirer server, the issuer server and the clearing house server, and public key information exists in the data signatures and can be synchronized to an intelligent contract in a alliance chain. The intelligent contract is a code segment which can run on a blockchain, and the execution process of the intelligent contract is identified and confirmed on the blockchain in a transaction form.
After the card issuer server receives a registration request for registering the virtual account triggered by a user, the card issuer server acquires account information corresponding to the virtual account and writes the acquired account information into a card issuer block chain node corresponding to the card issuer server. The virtual account information includes account balance information, issuer currency information, user name and the like.
And step S20, acquiring the account information from the card issuing blockchain node through an intelligent contract running in a blockchain system, and creating a virtual account according to the account information.
And step S30, synchronizing the account information to the receipt row blockchain node and the clearing row blockchain node based on the peer-to-peer network.
And after the account information is written into the card issuing bank blockchain node corresponding to the card issuing bank server, the intelligent contract running in the blockchain system acquires the account information from the card issuing bank blockchain node, and a virtual account is created according to the account information. After the account information is written into the card issuer block chain node corresponding to the card issuer server, the account information is synchronized to other block chain nodes in the alliance chain through P2P (Peer-to-Peer network), that is, to the singleton block chain node and the clearing bank block chain node, so as to realize the consistency of the account information in each block chain node. P2P is in centralized network, each party of transaction communicates with the data through a central node proxy, in P2P, the nodes can communicate directly with each other to form a peer-to-peer network structure, thus reducing the overhead of the central network, and the data generated by one node can simultaneously transmit broadcast to a plurality of nodes.
Step S40, after the intelligent contract receives the trade request, the intelligent contract modifies the account information according to the trade request, and synchronizes the modified account information to each block chain node of the alliance chain, wherein the alliance chain comprises a receiving single block chain node, a clearing bank block chain node and an issuing bank block chain node.
The smart contract detects whether a transaction request is received. And if the intelligent contract receives the transaction request, the intelligent contract modifies the corresponding account information according to the transaction request and synchronizes the modified account information to each block chain node in the alliance chain.
Further, the account information management method further includes:
step a, after the clearing bank block chain nodes receive the Renminbi exchange rate sent by the clearing bank server, synchronizing the Renminbi exchange rate to each block chain node of the alliance chain.
Further, after the block chain server receives an updating instruction for updating the Renminbi exchange rate, the Renminbi exchange rate is updated according to the updating instruction, and the updated Renminbi exchange rate is sent to the corresponding clearing bank block chain node. And after receiving the Renminbi exchange rate sent by the clearing bank server, the clearing bank block chain node synchronizes the Renminbi exchange rate to each block chain node in the alliance chain. Furthermore, after the intelligent contract for processing the exchange rate obtains the Renminbi exchange rate, the intelligent contract for processing the exchange rate records the Renminbi exchange rate and provides a corresponding interface for the intelligent contract with other functions to inquire the Renminbi exchange rate.
In this embodiment, after receiving a registration request for registering a virtual account through an issuer server, account information corresponding to the virtual account is acquired, and the account information is written into an issuer block chain node corresponding to the issuer server; acquiring the account information from the card issuing blockchain node through an intelligent contract running in a blockchain system, and creating a virtual account according to the account information; synchronizing the account information into a receipt line blockchain node and a clearing line blockchain node based on a peer-to-peer network; and after the intelligent contract receives a transaction request, the intelligent contract modifies the account information according to the transaction request and synchronizes the modified account information to each block chain node of a alliance chain, wherein the alliance chain comprises a receiving unit block chain node, a clearing bank block chain node and an issuing bank block chain node. The real-time synchronization of the account information among the card issuing bank block chain nodes, the receiving bank block chain nodes and the clearing bank block chain nodes is realized through the alliance chain, and the consistency of the account information in the card issuing bank server, the receiving bank server and the clearing bank server is ensured. And because the acquirer server and the clearing house server can inquire the account information in respective block chain link points, the issuer server is not required to send the account information, and a decentralized account system is constructed.

step S50, after the card issuing bank server receives the charging request, the card issuing bank server sends the charging request to the card issuing bank block chain node.
After the card issuing bank server receives the recharging request of the user, the card issuing bank server sends the recharging request to the card issuing bank block chain node so as to send the recharging request to the block chain system, and an intelligent contract for processing the recharging request obtains the recharging request from the card issuing bank block chain node.
Step S40 includes:
step S41, after the intelligent contract receives the recharging request sent by the card-issuing bank block chain node, the recharging amount corresponding to the recharging request is determined.
And step S42, modifying the account balance in the account information according to the recharging amount, and synchronizing the modified account balance to each block chain node of the alliance chain.
And when the intelligent contract for processing the recharging request receives the recharging request sent by the card issuing block chain node, determining the recharging amount corresponding to the recharging request. After the recharging amount is determined, the intelligent contract for processing the recharging request modifies the account balance in the account information according to the recharging amount, and synchronizes the modified account balance to each block chain node in the alliance chain. If the recharging amount corresponding to the recharging request is 10 harbor coins, the account balance in the account information is increased by 10 harbor coins, and the card issuing bank blockchain node broadcasts the transaction information to the receipt bank blockchain node and the clearing bank blockchain node, so that the account information among the card issuing bank blockchain node, the receipt bank blockchain node and the clearing bank blockchain node is synchronized.
Further, when the transaction request is a cash withdrawal request, the account information management method further includes:
and b, after the card issuer server receives the cash withdrawal request, sending the cash withdrawal request to the card issuer block chain node through the card issuer server.
After the card issuing bank server receives a cash withdrawal request of a user, the card issuing bank server sends the cash withdrawal request to the card issuing bank block chain node so as to send the cash withdrawal request to the block chain system, and an intelligent contract filled with the cash withdrawal request obtains the cash withdrawal request from the card issuing bank block chain node.
Step S40 further includes:
and c, after the intelligent contract receives the cash withdrawal request sent by the card issuing block chain node, determining the cash withdrawal amount corresponding to the cash withdrawal request.
And d, modifying the account balance in the account information according to the cash withdrawal amount, and synchronizing the modified account balance to each block chain node of the alliance chain.
And when the intelligent contract for processing the cash withdrawal request receives the cash withdrawal request sent by the card issuing block chain node, determining the cash withdrawal amount corresponding to the cash withdrawal request. After the cash withdrawal amount is determined, the intelligent contract for processing the cash withdrawal request modifies the account balance in the account information according to the cash withdrawal amount, and synchronizes the modified account balance to each block chain node in the alliance chain. If the withdrawal amount corresponding to the withdrawal request is 10 port coins, the account balance in the account information is reduced by 10 port coins, and the card issuing bank block link node broadcasts the transaction information to the receipt bank block link node and the clearing bank block link node, so that the account information among the card issuing bank block link node, the receipt bank block link node and the clearing bank block link node is synchronized.
In this embodiment, after the user consumes, the account information of the user after consumption is synchronized in real time by the alliance chain among the card issuing row block chain node, the receiving row block chain node and the clearing row block chain node.
Further, a third embodiment of the account information management method of the present invention is provided.
