Description
Technical Field
The invention relates to the field of cross-border data processing, in particular to a cross-border payment message notification processing method and device based on a block chain architecture.
Background
A renminbi Cross-border Payment System (CIPS) is a System for providing fund settlement service for the renminbi Cross-border Payment service of direct participants of international and foreign banking institutions and the like.
The business of CIPS is mainly divided into payment-type business processing, information-type business, and participant management business. The information service and the participant management service are initiated by the CIPS and directly received by the participant without the need of a capital settlement message notification service scene.
The message notification message of one CIPS consists of a message header and a message body, and the content of the message header sent by the CIPS is specific to different direct participants.
The following three types can be classified according to different message sending modes:
1) Point-to-point messaging.
The CIPS organizes the content of the message body aiming at the specific direct participant and sends the content to the participant; for example, the content of the account management notification message body is the relevant information of the account of the participant.
2) And sending a broadcast message.
The CIPS sends the content of the same message body to all direct participants; if the funding status white list is notified, all direct participants receive the same funding status white list sent by the CIPS.
3) And sending the multicast message.
The CIPS sends the content of the same message body to a group of direct participants; for example, message multicast in free format, CIPS selects a list of participants who need to send messages to form a message receiving group according to service requirements, and sends the content of the same message body to all participants in the group.
The following is a detailed scheme of the existing cross-border message notification processing and its disadvantages.
1. Point-to-point messaging.
Examples are as follows: the CIPS sends messages to direct participant a (example line number a 0001) and direct participant B (example line number a 0002) in a point-to-point manner, and examples of the messaging implementation are shown in fig. 1:
1) Stage one:
CIPS is direct participant a group message a, the header contains the line number a0001 of the direct participant a, and the body is "body one" (example);
CIPS is direct participant B group message B, the header contains the line number a0002 of direct participant B, and the body is "body two" (example).
That is, the peer-to-peer messaging scheme differs between the message header and the message body of the message for different direct participant groups.
2) And a second stage: the CIPS sends the combined message A and message B to a PMTS-COC (message centralized switching gateway, deployed in a cross-border inter-bank payment system operation center).
3) And a third stage: and the PMTS-COC distributes the direct participant row number filled in according to the message header to the PMTS-CAE (participant access end message transmission software deployed inside the cross-border inter-bank payment system participant) associated with the direct participant corresponding to the row number.
2. And sending a broadcast message.
Multicast and broadcast are implemented similarly, with the difference that broadcast messages are sent to all direct participants, whereas multicast messages are sent to a specified set of direct participants.
Examples are: the CIPS sends messages to all direct participants by broadcasting, and examples of the implementation of message sending are shown in fig. 2:
1) Stage one:
CIPS is all direct participant group message messages, one message for each direct participant group, the header contains the line number of the direct participant to be sent, e.g., the header of sending direct participant a contains line number a0001, the header of sending direct participant B contains line number a0002, and all message bodies are "body one" (example);
that is, the broadcast message transmission mode is different for the message headers of different direct participant groups, and the message bodies are the same.
2) And a second stage: and the CIPS sends the well-grouped message to the PMTS-COC.
3) And a third stage: and the PMTS-COC distributes the direct participant line number filled in the message header to the PMTS-CAE associated with the direct participant corresponding to the line number.
3. And sending the multicast message.
Examples are: the CIPS sends messages to a group of direct participants including direct participants a and B in a multicast manner, and an example of the implementation of the message sending is shown in fig. 3:
1) Stage one:
CIPS is direct participant a group message a, the header contains the line number a0001 of the direct participant a, and the body is "body one" (example);
CIPS is an immediate participant B group message B with the header containing the line number a0002 of the immediate participant B and the body being "body one" (example).
That is, the multicast message sending method is different for the message headers of different direct participant groups, and the message bodies are the same.
2) And a second stage: and the CIPS sends the organized message to the PMTS-COC.
3) And a third stage: and the PMTS-COC distributes the direct participant line number filled in according to the message header to the PMTS-CAE associated with the direct participant corresponding to the line number.
The disadvantages of the above solution include the following aspects:
1. the message distribution is complex, and the same message content is repeatedly sent:
the CIPS sends a message notice to the PMTS-COC, the PMTS-COC judges which direct participant is sent to according to the header information, and then the message notice is distributed to the PMTS-CAE corresponding to the corresponding direct participant.
The CIPS message notification issuing implementation method results in that if the same message is to be sent to multiple participants, different messages need to be organized for each participant, the message header includes the participant line number, and the message bodies are the same, because PMTS-COC needs to distribute the message through the header information.
The above disadvantages are that the message distribution is complicated, and the same message content cannot be shared among multiple participants, and the message content is repeatedly transmitted.
2. There is a possibility of loss of messages:
under abnormal conditions, the message notification issued by the CIPS does not reach the PMTS-CAE of a certain participant, at the moment, the participant cannot know that the message notification is issued by the CIPS in time, and the CIPS does not know whether the message notification is successfully sent to the direct participant or not.
In view of the above problems, no effective solution has been proposed.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Before describing embodiments of the present invention, terms related to embodiments of the present invention will be described.
(1) RMB Cross-border Payment System (Cross-border inter base Payment System, phase I, hereinafter CIPS): the cross-border payment system for RMB is one system for providing fund settlement service for RMB cross-border payment of direct participants in foreign and domestic bank organization. The CIPS supports the requirements of cross-border use of the RMB at each stage, including cross-border trade settlement of the RMB, cross-border currency fund settlement of a financial market and the like. The CIPS can provide a cross-border, cross-time zone payment settlement service to participants through a connection with a large payment system (hereinafter abbreviated as HVPS), a bond settlement system, and the like.
(2) The direct participants: the direct participant is an in-place banking institution which opens a fund account in the CIPS, has a CIPS line number and transacts the Renminbi cross-border payment business through the CIPS. The inline service system or dedicated front-end system of the direct participant is connected to the CIPS, through which commands are sent and received, which are transmitted over the private network or the general network.
(3) Indirect participants: the indirect participant is a foreign or international banking institution which does not open a fund account in the CIPS, has a CIPS bank number and has to entrust the direct participant to transact the Renminbi cross-border payment business, and the like. The indirect participants send and receive instructions to the CIPS through the direct participants.
In specific implementation, in the example of the present invention, the receiving participant node may include a direct participant (core participant) and an indirect participant (ordinary participant), where the direct participant may include an inbound direct participant (inbound direct participant node) and an outbound direct participant (outbound direct participant node), and the indirect participant may include: an intra-ambient indirect participant (intra-ambient indirect participant node) and an overseas indirect participant (overseas indirect participant node).
Because the inventor finds the problems of the cross-border payment (RMB and foreign currency) message notification processing scheme, the invention provides a cross-border payment message notification method based on the blockchain technology, namely a cross-border payment message notification processing method based on the blockchain architecture, and particularly the scheme mainly realizes the following ideas:
1. the existing implementation mode of broadcast and multicast of the existing cross-border payment message notification is to set a plurality of message notification messages for one message notification content group, and the line number of a certain participant is set in the header of each message for routing judgment, and the header information of the messages is the same. After the block chain is introduced, due to the interconnection and sharing of the block chain account book, one broadcast or multicast message notification can be seen by a plurality of participants at the same time, the original message distribution processing logic is simplified, the message is shared among the participants, and the repeated sending is not needed.
2. In the existing implementation mode, when a message is sent from a PMTS-COC to a PMTS-CAE, under an abnormal condition, the possibility of message loss exists, and an online participant can not autonomously obtain a message notification at present; and the authoritative, complete message notification and its status are stored in the CIPS, and participants are currently unable to query and download historical message notification records through the CIPS. After the block chain is introduced, the embodiment of the invention ensures the credibility and non-loss of the message notification record by virtue of the characteristics of distributed storage, non-falsification and authority book sharing of the block chain, and supports the inquiry and downloading of the historical record; meanwhile, an anonymous privacy protection mechanism is used to ensure the safety of information access and privacy protection.
3. In the embodiment of the invention, the inside and outside participants register to become members of the block chain network of the alliance, and the CIPS can also send message notification to the inside and outside participants.
The cross-border payment message notification processing scheme based on the blockchain architecture is described in detail below.
As shown in fig. 5, the cross border payment message notification processing participant node constitutes a blockchain node, which includes: the system comprises a CIPS node and a plurality of receiving participant nodes; fig. 4 is a flowchart illustrating a cross-border payment message notification processing method based on a blockchain architecture according to an embodiment of the present invention, as shown in fig. 4, the method includes the following steps:
step 101: the CIPS node organizes message notification message content aiming at a target receiving participant node, performs anonymous privacy encryption protection processing on the message notification message content by utilizing a public key of the target receiving participant node on a block chain in combination with a zero knowledge certification technology, constructs a message notification block according to a processing result, and adds the message notification block into the block chain;
step 102: each receiving participant node carries out anonymous identity verification aiming at the message notification block according to a zero-knowledge proof technology;
step 103: and the verified receiving participant node is used as the target receiving participant node to decrypt the message notification message content from the message notification block and output the decrypted message notification message content to a target user.
In the cross-border payment message notification processing method based on the blockchain architecture in the embodiment of the invention, as shown in fig. 5, during operation:
firstly, the CIPS node organizes the message notification message content of a target receiving participant node, anonymous privacy encryption protection processing is carried out on the message notification message content by utilizing a public key of the target receiving participant node on a block chain in combination with a zero-knowledge proof technology, a message notification block is constructed according to the processing result, the message notification block is added into the block chain, and at the moment, the cross-border payment message notification processing participant node on the chain knows that the message notification exists, namely the message notification is broadcasted to the chain.
Secondly, each receiving participant node performs anonymous identity verification for the message notification block according to a zero-knowledge proof technique.
And then, the verified receiving participant node is taken as the target receiving participant node to decrypt the message notification message content from the message notification block, and the decrypted message notification message content is output to the target user.
Therefore, compared with the existing cross-border payment message notification processing scheme, the scheme provided by the embodiment of the invention can achieve the following beneficial technical effects:
(1) The message distribution process is simplified, the message is shared among a plurality of participants, and the message does not need to be repeatedly sent: after the message is sent to the blockchain network, by using the blockchain as a carrier for information transfer and the shared characteristic, the related participants can receive and see the message, and the same message content does not need to be sent repeatedly.
(2) Promote message notification reachability and security of storage: by means of the distributed characteristic of the block chain, the messages are stored on a plurality of nodes of the block chain network in a distributed mode, the data storage safety is improved, the message messages sent to the block chain network can reach corresponding participants, and message loss caused by the reasons of single-party system paralysis, storage damage and the like is avoided.
(3) The message informs of the credibility: by means of the non-tampering characteristic of the block chain, the message notification is guaranteed not to be tampered manually, and the message notification is guaranteed to be credible.
(4) And meanwhile, an anonymous privacy protection mechanism is used to ensure the safety of information access and privacy protection: the message notification message is stored in each node of the block chain network, so that only relevant participants of the message notification can browse the message notification content, and irrelevant parties cannot see the sensitive information. Meanwhile, by means of an anonymous technology, the message informing receiver is unknown to other participants.
In summary, the technical scheme provided by the embodiment of the invention improves the accuracy and efficiency of the cross-border payment message notification processing, and simultaneously ensures the safety, reliability and stability of the cross-border payment message notification processing.
In specific implementation, the message notification message content can be output to the target user in the forms of display screen display, short message or mail and the like.
In the implementation, all participant nodes (participants) on the blockchain have their own public keys, and the public key of each participant is different. The encryption is privacy, namely, the privacy content is encrypted through a cryptography technology, so that the information is protected from being known, and the privacy can be realized through a symmetric key and an asymmetric key encryption technology in the cryptography. Anonymity is achieved through a zero knowledge proof mechanism, which may be implemented using existing zero knowledge proof techniques.
The following describes each step in the scheme provided by the embodiment of the present invention in detail with reference to fig. 5 to 10.
1. The inventors have also found the following technical problems:
as shown in fig. 6, in the existing cross-border payment message notification processing scheme, an indirect participant cannot directly access to the CIPS, and the indirect participant needs to forward a message notification issued by the CIPS through a direct participant, so that the message is cumbersome to transmit and cannot be shared in time.
In addition, existing cross-border payment message notification processing schemes do not support issuing message notifications to overseas participants: for reasons of cross-border networks, the CIPS only supports access of the intra-border direct participants at present, the extra-border participants mainly rely on the SWIFT network to perform information transfer with the intra-border direct participants, and specifically, after the message notification issued by the CIPS is only sent to the intra-border direct participants, the intra-border direct participants send the extra-border participants through the SWIFT network.
Since the inventor finds the above technical problem, a technical scheme for supporting the issuing of the message notification to the intra-environment indirect participants, the overseas direct participants and the indirect participants is proposed as follows.
In one embodiment, the receiving participant node may comprise: an inbound indirect participant node, an outbound direct participant node, and an outbound indirect participant node.
In the specific implementation, due to the implementation of the blockchain technology, the method supports the issue of message notification to the indoor indirect participants, and the outdoor direct and indirect participants. The intra-environment indirect participants, the overseas direct participants and the overseas indirect participants can be registered as members of the blockchain network, the cross-border payment network is extended to the overseas by means of the characteristics of block chain interconnection sharing, encryption and tamper resistance, and the intra-environment indirect participants, the overseas direct participants and the indirect participants can also receive message notifications sent by the CIPS.
2. The inventors have also found the following technical problems:
at present, the message issued by the CIPS in the cross-border payment message notification processing scheme needs to be stored in the internal service system by the participant, so that historical message query can be performed, the historical message stored in the internal service system of the participant may be lost, and the CIPS does not support the participant to query the historical issued message at present.
Since the inventor finds the above technical problem, a technical solution for supporting the history message query is proposed as follows.
In one embodiment, the receiving participant node may further receive a query request of a message notification history record input by a user, search in the blockchain shared ledger according to the query request, and output a query result to the user.
In the implementation, the historical message query is supported due to the implementation of the block chain technology. The message notification history records are stored in the block chain shared account book, and participants can inquire and download at any time.
3. A point-to-point messaging scheme based on a blockchain architecture is described below.
In one embodiment, the CIPS node organizing the message notification message content for the target receiving participant node, performing anonymous privacy encryption protection processing on the message notification message content by using a public key of the target receiving participant node on a block chain in combination with a zero-knowledge proof technique, constructing a message notification block according to a processing result, and adding the message notification block to the block chain may include:
the CIPS node organizes point-to-point message notification message content for a target receiving participant node, performs anonymous privacy encryption protection processing on the point-to-point message notification message content by using a public key of the target receiving participant node on a block chain in combination with a zero knowledge certification technology, constructs a point-to-point message notification block according to a processing result, and adds the point-to-point message notification block into the block chain;
the decrypting, by the verified receiving participant node as the target receiving participant node, the message notification packet content from the message notification block, and outputting the decrypted message notification packet content to the target user may include:
the verified receiving participant node is used as the target receiving participant node to decrypt the point-to-point message notification message content from the point-to-point message notification block and output the point-to-point message notification message content to a target user; the target receiving participant node is a receiving participant node of the point-to-point message on the block chain, and the target user is a receiving user of the point-to-point message.
In a specific implementation, the message to be sent through peer-to-peer messaging may be, for example, the content of the account management notification message body is the information related to the own account of the participant, and specifically, the peer-to-peer messaging processing scheme based on the blockchain architecture may include:
the CIPS is used for directly or indirectly aiming at specific intra-and-foreign participants, grouping the content of the message body of the participant, carrying out anonymous privacy encryption protection on the message by using the public key of the receiving participant on the blockchain in combination with a zero-knowledge proof technology, and then sending the message to the blockchain network.
