Detailed Description
In the prior art, the state information of the important blank certificates is stored in a central server in a bank, and other branch network points can acquire the state information of the important blank certificates by accessing the central server. However, there are a number of drawbacks to a centralized server. For example, because the state information of the important blank document is only stored by the centralized server, the problem of malicious tampering exists, the data is tampered in time, and other branch network points can consider the tampered data to be normal data, which is not beneficial to monitoring and managing the state information of the important blank document; in addition, when the centralized server fails, other branch network points cannot access the server, cannot acquire state information of important blank certificates, cannot recover data in the server once the data in the server is lost due to the failure, and has low reliability.
In order to solve the above problems, the present application provides a method, a system and a blockchain platform for processing important blank certificates.
In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Embodiment one:
an embodiment of the present application provides a method for processing an important blank document, and the method is specifically described below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a method for processing an important blank document is provided in an embodiment of the present application.
The processing method of the important blank certificate is applied to a alliance chain platform, and the alliance chain platform at least corresponds to the following two service end nodes: a first service end node and a second service end node; the method comprises the following steps:
step 101: the alliance chain platform receives the block uploaded by the first service end node; the block comprises change data, wherein the change data is generated by changing the state information of the important blank certificate by the first server node.
It should be understood that, before the first service end node may be one branch node of a bank and the second service end node may be another branch node of the bank, it is required to obtain change information of the important blank credential by the user before the first service end node uploads the block, then generate change data according to the change information, and package the change data into the block.
Wherein, the change information refers to the operation of the user on the important blank certificate, for example: warehouse entry, allocation, reception, adjustment, delivery, sale, loss reporting, voiding and the like. The change data refers to processing information generated after the service personnel processes the operation of the important blank certificate of the user, and can also comprise change information, and the service personnel belongs to the first service end node. The state information is affected by the change data, i.e. the state information will change at any time after the change data is generated.
And after the first server node packages and generates a block according to the change data, the block is sent to the alliance chain platform.
Step 102: the coalition chain platform verifies the block.
It will be appreciated that, rather than the first server node and/or the second server node uploading a block to the federated chain platform, the federated chain platform will add the block to the federated chain platform, but will need to verify the block. How the blocks are verified is described in detail below.
As a possible implementation manner, the federation chain platform configures a first subkey for the first server node; the alliance chain platform configures a second subkey for the second server node; wherein the first sub-key and the second sub-key are used to generate a first key; the federation chain platform verifying the block includes: and the alliance chain platform generates a second key according to the first sub-key uploaded by the first server node and the acquired second sub-key, and checks the block by judging whether the second key is consistent with the first key.
In the above embodiment, the federation chain platform distributes sub-keys to a plurality of server nodes in advance, each server node only knows its own sub-key, and when the server node sends a block to the federation chain platform, the sub-key is additionally sent to the federation chain platform to verify whether it is a node having authority to upload the block. When the node is judged to be the node with the uploading authority, the alliance chain platform calculates according to the subkey and the obtained subkeys of other nodes to obtain the key. If the key is the key which the alliance chain platform passes through authentication, proving that other nodes agree to the block uploaded by the node, that is, the other nodes agree to add the block to the alliance chain platform.
It is understood that the other nodes may be part of the server end nodes of the federation chain, or all of the server end nodes, and are not limited in this application.
In addition, the federation chain platform configuring a first subkey for the first server node includes: the alliance chain platform reconfigures the first subkey every other preset period to update the data of the first subkey; the federation chain platform configuring a second subkey for the second server node includes: and the alliance chain platform reconfigures the second subkey every other preset period to update the data of the second subkey. The sub-key of each server node is updated at random, so that the security of the sub-key is further ensured, and the risk that the sub-key is maliciously stolen by other nodes is further avoided.
Step 103: if the verification is passed, the alliance chain platform stores the block and updates the state information according to the change data, so that the first server node and/or the second server node acquire the updated state information through the alliance chain platform.
After verification is passed, the block is added to the alliance chain platform by the alliance chain, meanwhile, the alliance chain platform can obtain the change data, after the change data is obtained, the state information is updated according to the change data, and when other service end nodes access the alliance chain platform, the latest state information of the important blank certificate in the latest state can be obtained.
As a possible implementation manner, the coalition chain platform configures the identification of the important blank credential in advance; the method further comprises the following steps after the alliance chain platform updates the state information according to the change data: and the alliance chain platform stores the corresponding relation between the identification and the state information.
In the above embodiment, the correspondence between the identifier and the state information is stored, so that when other service end nodes access the federation chain platform, the latest state information of the important blank credential is quickly obtained, and the efficiency of obtaining the state information is further improved.
As a possible implementation manner, the coalition chain platform further corresponds to at least one user end node; the method further comprises the steps of: and the alliance chain platform generates the identifier through a hash algorithm pair according to the change data, so that the user end node obtains the state information corresponding to the identifier through the identifier according to the corresponding relation.
In the above embodiment, the federation chain platform includes not only a server node but also a user end node. The server node is a node with state information that modifies all important blank credentials, or is a control node. The user end node is a read-only node, and the important blank credential information that can be viewed by the user end node is limited.
It can be understood that each user end node only knows the change data of the own node on the own important blank certificate, and can generate an identifier by carrying out hash operation on the change data. And the user terminal node can obtain the state information corresponding to the identifier according to the corresponding relation through the identifier. Other user segment nodes can only acquire the important blank credential information of the user segment nodes, but cannot acquire the important blank credential information of other people, so that the privacy of the state information of the important blank credential is further improved.
According to the technical scheme, the application has the following advantages:
