Description
Technical field
The present invention relates to cross-border data processing field, in particular to a kind of cross-border payment message based on block chain framework is logical
Know processing method and processing device.
Background technique
The cross-border payment system of RMB (Cross-border Interbank Payment System, hereinafter referred to as
CIPS) be for local and overseas banking institution etc. directly participant the cross-border payment transaction of RMB provide with funds clearing service be
System.
The business of CIPS is broadly divided into payment class business processing, content service and participant's management business.Info class industry
It realizes in business and participant's management business and is initiated by CIPS, direct participant receives, logical without the message for carrying out capital settlement
Know business scenario.
The message informing message of one CIPS is made of heading and message body, for different direct participants, CIPS
The message packet head content of transmission is both for the direct participant's.
Following three types can be divided into according to the difference of message mode:
1) point-to-point message is sent.
CIPS is directed to specific direct participant, and harpoon is sent to the participant to holding in the message body of the participant；
If the content of account management notice message body is the account-related information of participant oneself.
2) broadcast message is sent.
CIPS is sent to the content of identical message body all direct participants；Such as register capital to state white list notice, institute
The direct participant having receives the identical of CIPS transmission and registers capital to state white list.
3) multicast message is sent.
The content of identical message body is sent to a certain group of direct participant by CIPS；Such as the message multicast in free-format,
CIPS chooses the participant list's formation message sink group for needing to send message, in identical message body according to business needs
Hold all participants being sent in the group.
The detailed protocol and its disadvantage of existing cross-border message informing processing are introduced below.
1. point-to-point message is sent.
Citing: CIPS sends messages to direct participant A (example line number A0001) by point-to-point mode and directly participates in
Person B (example line number A0002), message send implementation example as shown in Figure 1:
1) stage one:
CIPS is direct participant A group message packet A, and header includes the line number A0001 of direct participant A, and report body is " report
Body one " (example)；
CIPS is direct participant B group message packet B, and header includes the line number A0002 of direct participant B, and report body is " report
Body two " (example).
That is point-to-point message mode, to the header and report of the message packet of different direct patcicipant's gruops
Body is all different.
2) stage two: CIPS, being sent to PMTS-COC, (message concentrated exchange by the message packet A organized and message packet B
Gateway is deployed in cross-border banker's payment system operation center).
3) direct participant's line number that the stage three: PMTS-COC fills according to message packet head, it is corresponding to be distributed to line number
(participant's incoming end message transmissions software is deployed in cross-border banker's payment system ginseng to the associated PMTS-CAE of direct participant
Inside person).
2. broadcast message is sent.
Multicast is similar with the implementation of broadcast, and different places mainly broadcasts the message and sends all direct participants,
And multicast message is sent to one group of specified direct participant.
Citing: CIPS sends messages to all direct participants by broadcast mode, and message sends implementation example such as
Shown in Fig. 2:
1) stage one:
CIPS is all direct patcicipant's gruop message packets, and each directly participant organizes a message packet, header
Line number comprising the direct participant to be sent, such as sending the header of direct participant A includes line number A0001, is sent direct
That participant B includes line number A0002, and all message bodies are all " report body one " (example)；
That is broadcast the message sending method, different to the header of the message packet of different direct patcicipant's gruops,
And report body all.
2) message packet that the stage two: CIPS will have been organized, is sent to PMTS-COC.
3) direct participant's line number that the stage three: PMTS-COC fills according to message packet head, it is corresponding to be distributed to line number
The associated PMTS-CAE of direct participant.
3. multicast message is sent.
Citing: CIPS sends messages to one group of direct participant by multicast mode, and the direct participant of the group includes direct
Participant A and B, it is as shown in Figure 3 that message sends implementation example:
1) stage one:
CIPS is direct participant A group message packet A, and header includes the line number A0001 of direct participant A, and report body is " report
Body one " (example)；
CIPS is direct participant B group message packet B, and header includes the line number A0002 of direct participant B, and report body is " report
Body one " (example).
That is multicast message sending method, it is different to the header of the message packet of different direct patcicipant's gruops,
And report body all.
2) message packet that the stage two: CIPS will organize, is sent to PMTS-COC.
3) direct participant's line number that the stage three: PMTS-COC fills according to message packet head, it is corresponding to be distributed to line number
The associated PMTS-CAE of direct participant.
The shortcomings that above scheme includes the following aspects:
1. message distribution realizes complicated, identical message content repetition transmission:
CIPS sends message informing to PMTS-COC, then which judges to be sent to according to header information directly by PMTS-COC
Participant is met, the corresponding directly corresponding PMTS-CAE of participant is then distributed to.
This CIPS message informing issues implementation, if causing identical message being sent to multiple participants,
It then needing to organize different messages for each participant, heading includes participant's line number, and reports body all identical, the reason is that
PMTS-COC needs to carry out message distribution by header information.
Above-mentioned disadvantage is message distribution complexity, and identical message content can not be shared in multiple participants,
Message content repeats to send.
2. it is possible to there is loss in message:
In abnormal cases, the message informing that CIPS is issued does not reach the PMTS-CAE of some participant, at this time participant
It can not know that CIPS has issued message informing in time, and CIPS does not know whether message informing is successfully sent to directly participate in yet
Person.
In view of the above-mentioned problems, currently no effective solution has been proposed.

Cross-border trade settlement, the cross-border money-capital clearing in financial market etc..By with large-amount payment system (hereinafter referred to as HVPS), debt
The connection of certificate settlement system etc., CIPS can provide cross-border payment and settlement service across time zone for participant.
(2) direct participant: direct participant, which refers to, opens fund account in CIPS, possesses CIPS line number, passes through CIPS
Handle the domestic banking institution of the cross-border payment transaction of RMB.In the row of direct participant operation system or dedicated front-end system with
CIPS connection sends and receives instruction by CIPS, and instruction is transmitted by dedicated network or universal network.
(3) indirect participant: indirect participant, which refers to, does not open fund account in CIPS, possesses CIPS line number, it is necessary to entrust
Direct participant is ask to handle local and overseas banking institution of the cross-border payment transaction of RMB etc..Indirect participant passes through direct participant
Instruction is sent and received to CIPS.
When it is implemented, in present example receive participant node may include direct participant (core participant) and
Indirect participant (common participant), wherein direct participant may include domestic directly participant (domestic directly participant section
Point) and overseas direct participant's (direct participant node overseas), indirect participant may include: domestic participant (border indirectly
Interior indirect participant node) and overseas indirect participant's (indirect participant node overseas).
Due to inventor find cross-border payment (RMB and foreign currency) message informing processing scheme there are the problem of, propose
A kind of cross-border payment message notification method based on block chain technology, i.e., at the cross-border payment message notice based on block chain framework
Reason method, the specifically main realization approach of the program are as follows:
1. the broadcast of existing cross-border payment message notice and multicast is existing is achieved in that a message informing content group
The line number of some participant is arranged in the header of each message for multiple message informing messages, judges that the message is wanted for routing
It is sent to which participant, and the header information of message is all identical.And after introducing block chain, the embodiment of the present invention due to
The interconnectivity and sharing of block chain account book, a broadcast or multicast message informing can be seen by multiple participants simultaneously, simplify original
Some message distributions handle logic, realize that message is shared in multiple participants, and need not repeat to send.
2. existing implementation is in message under PMTS-COC transmission PMTS-CAE, abnormal conditions, there are information drop-outs
Possibility, participant can not independently reacquire message informing at present on line；And authority, complete message informing and its shape
State is stored in CIPS, and participant can not carry out the inquiry and downloading of history message Notification Record by CIPS at present.And draw
After entering block chain, the embodiment of the present invention guarantees by the characteristic of its distributed storage, can not distorting, shared authoritative account book
Message informing record it is credible and do not lose, support historical record can inquire and download；Anonymous Privacy Preservation Mechanism is used simultaneously,
Ensure the access and secret protection safety of information.

As shown in figure 5, cross-border payment message notifier processes participant node constitutes block chain node, the block chain node
It include: the cross-border payment system CIPS node of RMB and multiple reception participant nodes；Fig. 4 is in the embodiment of the present invention based on area
The flow diagram of the cross-border payment message notifier processes method of block chain framework, as shown in figure 4, this method comprises the following steps:
Step 101:CIPS node organization is directed to the message informing message content of intended recipient participant node, using described
Public key combination zero-knowledge proof technology of the intended recipient participant node on block chain, hides to message notice message content
Name privacy encipherment protection processing, constructs a message informing block according to processing result, and area is added in the message informing block
Block chain；
Step 102: each reception participant node is according to zero-knowledge proof technology, for the message informing block, into
The verifying of row anonymous Identity；
Step 103: the reception participant node being verified is as the intended recipient participant node from message informing
Message informing message content is decrypted in block, and the message informing message content decrypted is exported to target user.
Based on the cross-border payment message notifier processes method of block chain framework in the embodiment of the present invention, as shown in figure 5, work
When:
Firstly, CIPS node organization is directed to the message informing message content of intended recipient participant node, the mesh is utilized
Tag splice receives public key combination zero-knowledge proof technology of the participant node on block chain, carries out to message notice message content anonymous
The processing of privacy encipherment protection, constructs a message informing block according to processing result, and block is added in the message informing block
Chain, at this point, the cross-border payment message notifier processes participant node on chain recognizes there is such a message informing, i.e., this disappears
Breath notice is broadcast on chain.
Secondly, each reception participant node is hidden according to zero-knowledge proof technology for the message informing block
Name authentication.
Then, the reception participant node being verified is as the intended recipient participant node from message informing block
In decrypt message informing message content, the message informing message content decrypted is exported to target user.
Therefore, compared with existing cross-border payment message notifier processes scheme, scheme provided in an embodiment of the present invention can be with
Reach following advantageous effects:
(1) simplified message distribution flow realizes that message is shared in multiple participants, and need not repeat to send: message hair
After being sent to block chain network, by the carrier that block chain is transmitted as information, and shared characteristic, relevant participant may be used
To receive and see message, identical message content need not repeat to send.
(2) safety of message informing accessibility and storage is promoted: by the distributed nature of block chain, message distribution formula
Be stored on multiple nodes of block chain network, improve data storage safety, guarantee be sent to disappearing for block chain network
Breath message can all reach corresponding participant, also avoid information drop-out caused by the reasons such as folk prescription systemic breakdown, storage damage.
(3) message informing is credible: by the characteristic that can not distort of block chain, guaranteeing that message informing can not be distorted artificially, protects
Demonstrate,prove the credible of message informing.
(4) simultaneously using anonymous Privacy Preservation Mechanism, it is ensured that access and the secret protection safety of information: message informing message
There is preservation in each node of block chain network, guarantee only have the related participant of message informing to may browse through message informing content,
Irrelevant side can't see sensitive information.Simultaneously by anonymity technology, realize message informing recipient be who to other participants not
Known to.
To sum up, technical solution provided in an embodiment of the present invention improves the accuracy and effect of cross-border payment message notifier processes
Rate, while ensure that the security reliability and stability of cross-border payment message notifier processes.
When it is implemented, can be shown by display screen, the forms such as short message or mail export message informing message content to
Target user.
When it is implemented, all participant nodes (participant) on block chain have the public key of oneself, each participant
Public key be different.Encryption is to say to privacy, that is, pass through cryptological technique, is encrypted to privacy content, thus
Information is protected not to be known, privacy can be realized by the symmetric key in cryptography, asymmetric-key encryption technology.It is anonymous
It is realized by zero-knowledge proof mechanism, zero-knowledge proof can use existing zero-knowledge proof technology to realize.
Below in conjunction with Fig. 5 to Figure 10, to each step in scheme provided in an embodiment of the present invention describe in detail as
Under.
One, inventor also found following technical problem:
As shown in fig. 6, indirect participant cannot directly access in existing cross-border payment message notifier processes scheme
CIPS, the message informing that indirect participant must forward CIPS to issue by direct participant, message transmission is cumbersome, and can not be timely
It is shared.
In addition, existing cross-border payment message notifier processes scheme does not support issuing message notice to participant overseas: due to
The reason of cross-border network, CIPS only supports the access of domestic directly participant at present, and overseas participant relies primarily on SWIFT net
Network, and domestic directly participant carry out information transmitting, and specifically, the message informing that CIPS is issued can only be sent directly to be participated within the border
After person, participant overseas is sent by SWIFT network by domestic directly participant.
Since inventor has found the above technical problem, then proposes following support issuing message and notify to domestic indirect
Participant, the overseas directly or indirectly technical solution of participant.
In one embodiment, the reception participant node may include: domestic participant node indirectly, overseas directly
Participant node and overseas indirect participant node.
When it is implemented, due to the implementation for passing through block chain technology, support issuing message notice to domestic participant indirectly,
Directly or indirectly participant overseas.Domestic participant indirectly, overseas directly or indirectly participant is registrable as block chain network
Member, by block chain interconnectivity and sharing, encryption, anti-tamper characteristic, extend cross-border payment network to overseas, within the border between
Meet participant, overseas directly or indirectly participant can also receive the message informing issued from CIPS.
Two, inventor also found following technical problem:
Currently, in CIPS is issued in cross-border payment message notifier processes scheme message needs to be stored in by participant oneself
In portion's operation system, history message inquiry just can be carried out, and there is loss in the history message of participant's internal business systems storage
Possibility, CIPS does not support inquiry of the participant to history issuing message at present.
Since inventor has found the above technical problem, the following technical solution for supporting history message inquiry is then proposed.
In one embodiment, reception participant node can also receive looking into for the message informing historical record of user's input
Request is ask, is shared in account book and is searched according to inquiry request to block chain, query result is exported to user.
When it is implemented, supporting history message inquiry due to the implementation for passing through block chain technology.Message informing historical record
It is stored in block chain to share in account book, participant can inquire and download at any time.
Three, the point-to-point message based on block chain framework is described below and sends processing scheme.
In one embodiment, CIPS node organization is directed to the message informing message content of intended recipient participant node,
Using public key combination zero-knowledge proof technology of the intended recipient participant node on block chain, in message notice message
Hold and carry out anonymous privacy encipherment protection processing, a message informing block is constructed according to processing result, by the message informing area
Block chain is added in block, may include:
CIPS node organization is directed to the point-to-point message informing message content of intended recipient participant node, utilizes the mesh
Tag splice receives public key combination zero-knowledge proof technology of the participant node on block chain, to point-to-point message informing message content into
Row anonymity privacy encipherment protection processing, constructs a point-to-point message informing block according to processing result, point-to-point disappears described
Block chain is added in breath notice block；
The reception participant node being verified is solved from message informing block as the intended recipient participant node
The message informing message content decrypted is exported to target user, may include: by close outbound message notice message content
The reception participant node being verified is as the intended recipient participant node from point-to-point message informing area
Point-to-point message informing message content is decrypted in block, and point-to-point message informing message content is exported to target user；It is described
Intended recipient participant node is the reception participant node of the point-to-point message on block chain, and target user is point pair at this time
The reception user of point message.
When it is implemented, the message sent by point-to-point message is needed to can be as in account management notice message body
