Description

Block chain-based account information query method, device and system
Technical Field
The present invention relates to the field of blockchain technologies, and in particular, to a blockchain-based account information query method, device, and system.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
The account information inquiry service refers to a service that a customer entrusts a commercial bank or a non-financial payment service organization to inquire one or more banks designated by an authorizer to settle account information through a payment clearing system, and inquiry contents can comprise account balance, transaction detail and the like. The account information inquiry service is sent one by one, and the initiator obtains the inquiry result in real time.
At present, the flow of the existing account information query service is approximately as follows: the inquiring row (can be a commercial bank or a non-financial payment service organization) system initiates an account information inquiring application according to an account information inquiring request of a user side, and then the account information inquiring application is forwarded to the inquired row system by a payment clearing system; and the queried row system returns an account information query response to the payment clearing system according to the received account information query application, and the account information query response is forwarded to the query row by the payment clearing system.
In order to ensure the information security of the account owners, the queried row system usually performs identity authentication on the account information query initiator before returning the account information query response, and the corresponding account information query flows are not identical in different authentication modes.
Currently, the authentication modes adopted by the existing account information inquiry service mainly comprise the following three types:
first, the queried row system performs identity verification on the queried account according to the account information cross-row query protocol. If the account owner and the queried row system sign the account information cross-row query protocol, the query row system can contain the protocol number of the account information cross-row query protocol signed by the account owner and the queried row system when initiating the account information query application, so that the queried row system directly returns an account information query response according to the protocol authentication result after receiving the account information query application forwarded by the payment clearing system, and the account information query response is forwarded to the query row system by the payment clearing system. As shown in fig. 1, the specific flow may include the following steps:
s1, a query line system composes an account information query application according to an account information query request of a user side, wherein the query request comprises a protocol number compiled by a query line, and a digital signature is compiled and then sent to a payment clearing system;
S2, the payment clearing system receives an account information inquiry application sent by the inquiry line system, performs validity check and digital signature verification on the account information inquiry application, and forwards the account information inquiry application to the inquired line system after the validity check and the digital signature verification pass;
and S3, after the inquired line system receives the account information inquiry application forwarded by the payment clearing system, carrying out validity check and digital signature verification on the account information inquiry application, and returning an account information inquiry response to the payment clearing system after the validity check and the digital signature verification pass.
And S4, the payment clearing system receives the account information inquiry response sent by the inquired line system, performs validity check and digital signature verification on the account information inquiry response, and forwards the account information inquiry response to the inquired line system after the validity check and the digital signature verification pass. After receiving the account information inquiry response forwarded by the payment clearing system, the inquiry line system performs validity check and digital signature check on the account information, and when the validity check and the digital signature check pass, the inquiry line system outputs the account information (including but not limited to account numbers, account names, account opening banks, account states, balances, available balances and the like) of the inquired accounts to the user side.
Second, the queried account is authenticated by the query line system sending authentication information (e.g., a user name and password) to the queried line system. After the inquiring line system initiates an account information inquiring application and forwards the account information inquiring application to the inquired line system by the payment clearing system, the inquired line system returns an account information inquiring identity authentication request and forwards the account information inquiring identity authentication request to the inquiring line system by the payment clearing system, and then the inquiring line system sends account information inquiring identity authentication prompt information to the user side, so that the user side sends the identity authentication information of the inquired account to the inquired line system, and after the received identity authentication information of the inquired account passes, the inquired line system returns an account information inquiring response and forwards the account information inquiring identity authentication prompt information to the inquiring line system by the payment clearing system. As shown in fig. 2, the specific flow may include the following steps:
s1, a query line system composes an account information query application according to an account information query request of a user side, and sends a payment clearing system after a digital signature is added;
s2, the payment clearing system receives an account information inquiry application sent by the inquiry line system, performs validity check and digital signature verification on the account information inquiry application, and forwards the account information inquiry application to the inquired line system after the validity check and the digital signature verification pass;
S3, the queried row system receives the account information query application forwarded by the payment clearing system, performs validity check and digital signature verification on the account information query application, and returns an account information query identity authentication request to the payment clearing system after the validity check and the digital signature verification pass;
s4, the payment clearing system receives an account information inquiry identity authentication request sent by the inquired line system, performs validity check and digital signature verification on the account information inquiry identity authentication request, and forwards the account information inquiry identity authentication request to the inquired line system after the validity check and the digital signature verification pass;
s5, the inquiring row system receives the account information inquiring identity authentication request forwarded by the payment clearing system, performs validity check and digital signature check on the account information inquiring identity authentication request, and sends account information inquiring identity authentication prompt information to the user side after the validity check and the digital signature check pass, so that the user side sends the identity authentication information (such as account number, password and the like) of the inquired account to the inquired row system; s5-1, sending account information inquiry identity authentication prompt information to a user by an inquiry line system; s5-2, the user sends identity authentication information of the queried account to the queried row system;
S6, the queried row system receives the identity authentication information of the queried account, performs identity authentication on the queried account, and after the identity authentication passes, forms an account information query success response, and sends the account information query success response to the payment clearing system after the digital signature is added;
and S7, the payment clearing system receives the account information inquiry response sent by the inquired line system, performs validity check and digital signature verification on the account information inquiry response, and forwards the account information inquiry response to the inquired line system after the validity check and the digital signature verification pass. The inquiring system receives the account information inquiring response forwarded by the payment clearing system, performs validity check and digital signature check on the account information inquiring response, and outputs the account information (including but not limited to account number, user name, account opening bank, account state, balance, available balance and the like) of the inquired account to the user terminal after the validity check and the digital signature check pass.
Third, the user end sends identity authentication information (e.g. user name and password) to the queried row system to perform identity verification on the queried account. When the inquiring line system initiates an account information inquiring application containing the identity authentication information of the inquired account, and the payment clearing system forwards the account information inquiring application to the inquired line system, the inquired line system carries out identity authentication on the inquired account according to the identity authentication information of the inquired account contained in the received account information inquiring application, directly returns an account information inquiring response according to an authentication result, and forwards the account information inquiring response to the inquiring line system. As shown in fig. 3, the specific flow may include the following steps:
S1, a query line system composes an account information query application according to an account information query request of a user side, wherein the query request comprises an account name and a password of an account opening line of a client, and a digital signature is added and then a payment clearing system is sent;
s2, the payment clearing system receives an account information inquiry application sent by the inquiry line system, performs validity check and digital signature verification on the account information inquiry application, and forwards the account information inquiry application to the inquired line system after the validity check and the digital signature verification pass;
s3, the inquired line system receives the account information inquiry application forwarded by the payment clearing system, performs validity check (including checking the validity of account opening line account numbers, account names and passwords) and digital signature verification on the account information inquiry application, and returns account information inquiry response to the payment clearing system after the validity check and the digital signature verification are passed;
and S4, the payment clearing system receives the account information inquiry response sent by the inquired line system, performs validity check and digital signature verification on the account information inquiry response, and forwards the account information inquiry response to the inquired line after the validity check and the digital signature verification pass. The inquiring row system receives the account information inquiring response forwarded by the payment clearing system, performs validity check and digital signature check on the account information inquiring response, and outputs inquired account information (including account number, user name, account opening bank, account state, balance, available balance and the like) to a user side (account information inquiring initiator) after the validity check and the digital signature check pass.
As can be seen from fig. 1, 2 and 3, in the existing account information query flow, service data is transmitted back and forth in series through a query line system, a payment clearing system and a queried system, and the following disadvantages exist in the serial manner:
(1) the service processing efficiency is to be improved. The serial data transmission makes the communication and processing process complex, not only affects the service processing efficiency, but also any link error may cause the failure of the whole account information inquiry service, thereby needing to reinitiate the account information inquiry request.
(2) The reliability of data transmission is to be improved. Any party system has network interruption or abnormal processing, which can cause data loss, thereby causing inconsistent information processing states of the party systems.
(3) There is a risk of the data being tampered with. And the data is transmitted in a serial mode, and the risks of tampering the data exist in the intermediate links.
In view of the above problems, no effective solution has been proposed at present.

The order of steps involved in the embodiments is illustrative of the practice of the application, and is not limited and may be suitably modified as desired.
An embodiment of the present invention provides a system for querying account information based on a blockchain, and fig. 4 is a schematic diagram of the system for querying account information based on a blockchain provided in the embodiment of the present invention, as shown in fig. 4, where the system includes: a blockchain network 10, a query line system 20, a queried line system 30, and a payment clearing system 40; query row system 20 accesses the blockchain network through a first blockchain client 50-1, and queried row system 30 accesses the blockchain network through a second blockchain client 50-2; the payment clearing system 40 accesses the blockchain network through the third blockchain client 50-3, respectively.
The query line system 20 is configured to initiate an account information query application to the blockchain network 10 according to an account information query request of the user side; the queried row system 30 is configured to receive an account information query application pushed by the blockchain network 10, and return an account information query response result to the blockchain network 10 according to the received account information query application; the payment clearing system 40 is used for receiving and recording account information inquiry application and account information inquiry response results pushed by the blockchain network 10; the query line system is further configured to receive an account information query response result pushed by the blockchain network 10, and return an account information query result to the user terminal 60 according to the received account information query response result.
It should be noted that, in the embodiment of the present invention, the query line system 20, the queried line system 30 and the payment clearing system 40 may all access the blockchain network through respective blockchain clients, and implement data transmission with the blockchain network 10 through the blockchain clients, so as to synchronize respective service processing data of the query line system 20, the queried line system 30 or the payment clearing system 40 to the blockchain network 10, or obtain service processing data of other systems pushed by the blockchain network 10 based on the intelligent contract. When the blockchain network 10 is in butt joint with the query line system 20, the queried line system 30 and the payment clearing system 40, the blockchain client can adopt a pre-application mode to butt joint with the production environments of the query line system 20, the queried line system 30 and the payment clearing system 40, so that the aim of quickly connecting the query line system 20, the queried line system 30 and the payment clearing system 40 into the blockchain network is fulfilled.
Optionally, in the embodiment of the present invention, the interface protocol between the query line system 20, the queried line system 30 or the payment clearing system 40 and the blockchain client adopts HTTP protocol; the interface protocol between the block chain client and the block chain network adopts a SOCKET protocol; and transmitting payment service data between network nodes in the block chain network by adopting a JSON format message.
It should be noted that, the account information query system shown in fig. 4 is suitable for a scenario in which the queried row system performs identity verification on the queried account according to the account information cross-row query protocol, and a scenario in which the query row system sends identity authentication information to the queried row system to perform identity verification on the queried account. For the scenario that the user end sends the identity authentication information to the queried row system to perform identity verification on the queried account, the account information query system shown in fig. 5 needs to be adopted, and as shown in fig. 5, the queried row system 30 is further configured to return an account information query identity authentication request to the blockchain network 10 according to the received account information query application after receiving the account information query application pushed by the blockchain network 10; the query line system 20 is further configured to receive an account information query identity authentication request pushed by the blockchain network 10, query the identity authentication request according to the received account information, and return identity authentication prompt information to the user terminal 60, where the identity authentication prompt information is used to prompt the user terminal 60 to send the identity authentication information to the queried line system; the queried row system 30 is further configured to receive identity authentication information from the user terminal 60, authenticate the received identity authentication information, and return an account information query response result to the blockchain network 10 according to the authentication result.
For the blockchain-based account information query system shown in fig. 4, the flow of implementing an account information query service among the blockchain network 10, the query line system 20, the queried line system 30 and the payment clearing system 40 is as follows:
s1, the query line system initiates an account information query application according to an account information query request of a user side and submits the account information query application to a blockchain network. Optionally, before submitting the information query application to the blockchain network, the query line system may further add a digital signature to the account information query application, and submit the account information query application to the blockchain network after adding the digital signature. If the adopted protocol authentication mode is that the queried row system performs identity verification on the queried account according to the account information cross-row query protocol, the account information query application initiated by the query row system can contain protocol information (for example, the protocol number compiled by the queried row); if the protocol authentication mode is that the inquiring line system sends the identity authentication information to the inquired line system to carry out identity verification on the inquired account, the account information inquiring request initiated by the inquiring line system can contain the identity authentication information (such as account name and password of the opening line) of the inquired account.
S2, the payment clearing system and the queried row system receive account information query applications pushed by the blockchain network in a parallel mode. Optionally, the blockchain network may push an account information query application initiated by the query line system to the payment clearing system and the queried line system based on the intelligent contract. Because the payment clearing system and the queried line system adopt a parallel mode to receive the account information query application pushed by the blockchain network, the account information query application from the queried line system can be received almost simultaneously.
S3, the queried line system performs validity check (including checking validity of account opening line account numbers, account names and passwords) and digital signature verification on the account information query application, returns account information query response after the validity check and the digital signature verification pass, and submits the account information query response to the blockchain network. And the payment clearing system performs validity check and records on the received account information inquiry application. Optionally, the queried row system may also submit the account information query response with the digital signature added to the blockchain network.
S4, the payment clearing system and the query line receive account information query response pushed by the blockchain network in a parallel mode. The inquiring system performs validity check and digital signature check on the account information inquiring response, and outputs inquired account information (including but not limited to account number, user name, account opening bank, account state, balance, available balance and the like) to a user side (namely terminal equipment used by an inquirer) after the validity check and the digital signature check are passed. And the payment clearing system performs validity check and records on the received account information inquiry response.
For the blockchain-based account information query system shown in fig. 5, the flow of implementing an account information query service among the blockchain network 10, the query line system 20, the queried line system 30 and the payment clearing system 40 is as follows:
s1, the query line system initiates an account information query application according to an account information query request of a user side and submits the account information query application to a blockchain network. Likewise, the query line system may submit the digitally signed account information query application to the blockchain network.
S2, the payment clearing system and the queried row system receive account information query applications pushed by the blockchain network in a parallel mode.
