Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings, the described embodiments should not be construed as limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

Before further detailed description of the embodiments of the present invention, terms and expressions mentioned in the embodiments of the present invention are explained, and the terms and expressions mentioned in the embodiments of the present invention are applied to the following explanations.

1) Transactions (transactions), equivalent to the computer term "Transaction," include operations that need to be committed to a blockchain network for execution and do not refer solely to transactions in the context of commerce, which embodiments of the present invention follow in view of the convention colloquially used in blockchain technology.

For example, a deployment (deployment) transaction is used to install a specified smart contract to a node in a blockchain network and is ready to be invoked; the Invoke (Invoke) transaction is used to append records of the transaction in the blockchain by invoking the smart contract and to perform operations on the state database of the blockchain, including update operations (including adding, deleting, and modifying key-value pairs in the state database) and query operations (i.e., querying key-value pairs in the state database).

2) A Block chain (Blockchain) is a storage structure for encrypted, chained transactions formed from blocks (blocks).

For example, the header of each block may include hash values of all transactions in the block, and also include hash values of all transactions in the previous block, so as to achieve tamper resistance and forgery resistance of the transactions in the block based on the hash values; newly generated transactions, after being filled into the tiles and passing through the consensus of nodes in the blockchain network, are appended to the end of the blockchain to form a chain growth.

3) A Blockchain Network (Blockchain Network) incorporates new blocks into a set of nodes of a Blockchain in a consensus manner.

4) Ledger (legger) is a general term for blockchains (also called Ledger data) and state databases synchronized with blockchains.

Wherein, the blockchain records the transaction in the form of a file in a file system; the state database records the transactions in the blockchain in the form of different types of Key (Key) Value pairs for supporting fast query of the transactions in the blockchain.

5) Intelligent Contracts (Smart Contracts), also known as chain codes (chaincodes) or application codes, are programs deployed in nodes of a blockchain network, and the nodes execute the intelligent Contracts called in received transactions to perform operations of updating or querying key-value data of the account database.

6) Consensus (Consensus), a process in a blockchain network, is used to agree on transactions in a block among a plurality of nodes involved, the agreed block is to be appended to the end of the blockchain, and the mechanisms for achieving Consensus include Proof of workload (PoW, Proof of Work), Proof of rights and interests (PoS, Proof of equity (DPoS), Proof of granted of shares (DPoS), Proof of Elapsed Time (PoET, Proof of Elapsed Time), and so on.

7) The student identity information is used for representing the student identity information of the target users in different learning stages, and the student identity information of each target user comprises the school achievement, the prize winning record, the daily performance record, the interest and hobby information, the professional skill information, the personality psychological information, the participated public welfare activity information and the interpersonal relationship information of the target user in the current stage.

Referring to fig. 1, fig. 1 is a schematic diagram of a usage environment of a method for processing student identity information in a blockchain network according to an embodiment of the present invention, including a blockchain network 200 (exemplarily shown to include a node 210-1 to a node 210-3), a blockchain network management platform 300, a current institution node system 400 (exemplarily shown to belong to a terminal 600-1 of the current institution node system 400 and a graphical interface 610-1 thereof), and a regulatory institution node system 500 (exemplarily shown to belong to a terminal 600-2 of the regulatory institution node system 500 and a graphical interface 610-2 thereof), which are described below.

The type of the blockchain network 200 is flexible and various, and may be any one of a public chain, a private chain, or a federation chain, for example. Taking a public link as an example, electronic devices such as user terminals and servers of any service entity can access the blockchain network 200 without authorization; taking a federation chain as an example, an electronic device (e.g., a terminal/server) under the jurisdiction of a service entity after obtaining authorization may access the blockchain network 200, and at this time, become a special type of node in the blockchain network 200, i.e., a client node.

Note that the client node may provide only functionality that supports the initiation of transactions by the business entity (e.g., for uplink storage of data or for querying of data on the chain), and may be implemented by default or selectively (e.g., depending on the specific business requirements of the business entity) for the functionality of the conventional (native) node 210 of the blockchain network 200, such as the ranking functionality, consensus services, ledger functionality, etc., described below. Therefore, the data and the service processing logic of the service subject can be migrated into the block chain network 200 to the maximum extent, and the credibility and traceability of the data and service processing process are realized through the block chain network 200.

The blockchain network 200 receives transactions submitted by client nodes (e.g., terminal 600-1 shown in fig. 1 as belonging to the current organization node system 400 and terminal 600-2 shown in fig. 1 as belonging to the supervisory organization node system 500) from different business entities (e.g., the current organization node system 400 and the supervisory organization node system 500 shown in fig. 1), performs the transactions to update or query the ledger, and displays various intermediate or final results of performing the transactions at user interfaces of the terminals (e.g., graphical interface 610-1 of terminal 600-1, graphical interface 610-2 of terminal 600-2). It is to be understood that, in the above, the blockchain network 200 receiving the transaction and executing the transaction specifically refers to the native node 210 in the blockchain network 200, and of course, when the client node of the service subject has the function (e.g., the consensus function, the ledger function) of the native node 210 in the blockchain network 200, the corresponding client node may also be included.

An exemplary application of the blockchain network is described below by taking an example that a plurality of service entities (different organization node systems) access the blockchain network to realize management of logistics data.

Referring to fig. 1, after obtaining authorization of the blockchain network management platform 300, a plurality of business entities involved in a logistics link, such as a current agency node system 400 and a supervision agency node system 500, a terminal 600-1 of the current agency node system 400 and a terminal 600-2 of the supervision agency node system 500 may access the blockchain network 200.

The service person of the current institution node system 400 logs in the current institution node system 400 in the graphic interface 610-1 of the terminal 600-1, inputs student identity information generated by the user in the current institution learning process, or a query request of a target user to be queried, wherein the query request is sent to the blockchain network management platform 300, the blockchain network management platform 300 generates a transaction corresponding to the update operation/query operation according to the received query request, the smart contract that needs to be invoked to implement the update/query operation, and the parameters passed to the smart contract are specified in the transaction, which also carries a digital signature signed by the current authority node system 400 (e.g., obtained by encrypting a digest of the transaction using a private key in a digital certificate of the current authority node system 400), and broadcasts the transaction to the blockchain network 200.

When a transaction is received in the node 210 in the block chain network 200, the digital signature carried by the transaction is verified, after the digital signature is successfully verified, whether the current organization node system 400 has the transaction right is determined according to the identity of the current organization node system 400 carried in the transaction, and the transaction fails due to verification judgment of any one of the digital signature and the right verification. After successful verification, node 210 signs its own digital signature (e.g., by encrypting the digest of the transaction using the private key of node 210-1) and continues to broadcast in blockchain network 200.

After the node 210 with the sorting function in the blockchain network 200 receives the transaction successfully verified, the transaction is filled into a new block and broadcasted to the node providing the consensus service in the blockchain network 200.

The node 210 providing the consensus service in the blockchain network 200 performs the consensus process on the new block to reach an agreement, the node 210 providing the ledger function appends the new block to the tail of the blockchain, and performs the transaction in the new block: for the transaction of submitting and updating the student identity information, updating the key value pair corresponding to the student identity information in the account book database; and for the transaction of inquiring and updating the student identity information, inquiring the key value pair corresponding to the student identity information from the account book database, and returning an inquiry result.

Similarly, a service person on the side of the supervision authority node system 500 may log in the supervision authority node system 500 in the graphical interface 610-2 of the terminal 600-2 (where the supervision authority node system may be configured with the highest authority to view the student identity information uploaded by different institutions), input a student identity information query request, where the query request is sent to the blockchain network management platform 300, generate a transaction corresponding to the update operation/query operation by the blockchain network management platform 300 according to the received query request, specify an intelligent contract to be invoked for implementing the update operation/query operation in the transaction, and parameters passed to the intelligent contract, and the transaction also carries a digital signature signed by the current authority node system 400 (for example, obtained by encrypting a digest of the transaction using a private key in a digital certificate of the current authority node system 400), and broadcasts the transaction to the blockchain network 200. Further, it can be understood that the type of data that nodes (business entities) of different organizations can query/update in the blockchain network 200 can be realized by restricting the authority of transactions that the business entities can initiate, for example, when the current organization node system 400 has the authority to initiate transactions for querying target student identity information, a business person of the current organization node system 400 can input a target student identity information query request in the graphical interface 610-1 of the terminal 600-1, and generate a transaction for querying the target student identity information by the blockchain network management platform 300 to be broadcast to the blockchain network 200 to obtain corresponding target student identity information from the blockchain network 200; when the supervisor node system 500 has the right to initiate a transaction for inquiring student identity information, a service person on the side of the supervisor node system 500 may input a student identity information inquiry request in the graphical interface 610-2 of the terminal 600-2, and generate a transaction broadcast for inquiring student identity information by the blockchain network management platform 300 to the blockchain network 200, so as to obtain corresponding student identity information from the blockchain network 200.

An exemplary functional architecture of a block chain network provided in an embodiment of the present invention is described below, referring to fig. 2, fig. 2 is a functional architecture schematic diagram of a block chain network 200 provided in an embodiment of the present invention, which includes an application layer 201, a consensus layer 202, a network layer 203, a data layer 204, and a resource layer 205, which are described below respectively.

The resource layer 205 encapsulates computing, storage, and communication resources that implement each node 210 in the blockchain network 200, such as computing, storage, and communication resources in computers, servers/clusters, and clouds, abstracts and provides a uniform interface to the data layer 204 to shield the underlying hardware implementing the resource layer 205 from differences.

The computing resources include various forms of processors such as a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), and a Field-Programmable Gate Array (FPGA).

The storage resources include various types of storage media such as various volatile memories and nonvolatile memories. The nonvolatile Memory may be a Read Only Memory (ROM) or a Programmable Read-Only Memory (PROM). Volatile Memory can be Random Access Memory (RAM), which acts as external cache Memory.

The communication resources include various links for communication between nodes 210 of the blockchain network, between the blockchain network 200 and the traffic master.

The data layer 204 encapsulates various data structures that implement the ledger, including blockchains implemented in files in a file system, state databases of the key-value type, and presence certificates (e.g., hash trees of transactions in blocks).

The network layer 203 encapsulates the functions of a Point-to-Point (P2P) network protocol, a data propagation mechanism and a data verification mechanism, an access authentication mechanism and service agent identity management.

Wherein the P2P network protocol implements communication between nodes 210 in the blockchain network 200, the data propagation mechanism ensures propagation of transactions in the blockchain network 200, and the data verification mechanism implements reliability of data transmission between nodes 210 based on cryptography methods (e.g., digital certificates, digital signatures, public/private key pairs); the access authentication mechanism is used for authenticating the identity of the service subject added into the block chain network 200 according to an actual service scene, and endowing the service subject with the authority of accessing the block chain network 200 when the authentication is passed; the business entity identity management is used to store the identity of the business entity that is allowed to access blockchain network 200, as well as the permissions (e.g., the types of transactions that can be initiated).

The consensus layer 202 encapsulates the functions of the mechanism for the nodes 210 in the blockchain network 200 to agree on a block (i.e., a consensus mechanism), transaction management, and ledger management.

The consensus mechanism comprises consensus algorithms such as POS, POW and DPOS, and the pluggable consensus algorithm is supported.

The transaction management is configured to verify a digital signature carried in the transaction received by the node 210, verify identity information of the service entity, and determine whether the node has an authority to perform the transaction (read related information from the identity management of the service entity) according to the identity information; for the service agents authorized to access the blockchain network 200, the service agents all have digital certificates issued by the certificate authority, and the service agents sign the submitted transactions by using private keys in the digital certificates of the service agents, so that the legal identities of the service agents are declared.

Account book management: for maintaining block chains and ledger databases. For the block with the consensus, adding the block to the tail of the block chain; and executing the transaction in the block which obtains the consensus, updating the key-value pairs in the state database when the transaction comprises an updating operation, inquiring the key-value pairs in the account book database when the transaction comprises an inquiring operation, and returning an inquiring result to the business body. The method supports query operations of multiple dimensions of the account book database, and comprises the following steps: querying the chunk based on the chunk sequence number (e.g., hash value of the transaction); inquiring the block according to the block hash value; inquiring a block according to the transaction serial number; inquiring the transaction according to the transaction serial number; inquiring account data of a business main body according to an account (serial number) of the business main body; and inquiring the block chain in the channel according to the channel name.

The application layer 201 encapsulates various services that the blockchain network can implement, including tracing, crediting, and verifying transactions.

Referring to fig. 4, fig. 4 is an optional flowchart of the method for processing student identity information in a blockchain network according to the embodiment of the present invention, and it can be understood that the steps shown in fig. 4 may be executed by various electronic devices operating a student identity information processing apparatus, for example, a dedicated terminal, a server, or a server cluster with a student identity information processing function. The following is a description of the steps shown in fig. 4.

Step 401: the student identity information processing device acquires student identity information of a target user;

wherein the student identity information can be used to characterize the identity information of the target user at different learning stages (or in different institutions).

Step 402: and verifying the student identity information of the target user, and determining the authority information of the verified student identity information.

In some embodiments of the present invention, verifying the student identity information of the target user, and determining the authority information corresponding to the verified student identity information may be implemented in the following manner:

and verifying the student identity information of the target user, and when the student identity information of the target user is matched with the original record of the target user, determining the management authority nodes corresponding to the verified student identity information as the current institution node and the supervision institution node. The current institution node has the authority to check and modify the student identity information of the target user (before data is not linked up), and after the corresponding authority is configured to the supervision institution node, the supervision institution node can check the student identity information stored in the blockchain network and timely acquire the adjustment and/or increase of the user information. When the student identity information is used for representing the student identity information of the target user in different learning stages, and the target user has a wide range of types and a large number of student identity information in the learning process of the current institution, the matching of the authority information of the corresponding node and the original record of the target user can be ensured when the student identity information of the target user is matched with the original record of the target user, and the accuracy of the student identity information stored in the block chain network can be ensured.

when the student identity information of the target user is not matched with the original record of the target user, determining that the management authority node of the verified student identity information is a current mechanism node, and sending prompt information, wherein the prompt information is used for prompting the adjustment of the student identity information of the target user. The current mechanism node has the authority of checking and modifying the student identity information of the target user (before chaining of data), and the student identity information is used for representing the student identity information of the target user in different learning stages, so that the type of the generated student identity information is wide and the quantity of the generated student identity information is large in the learning process of the target user in the current mechanism, and therefore the student identity information of the target user is verified to be matched with the original record of the target user, and the accuracy of the student identity information stored in the block chain network is further ensured.

Step 403: acquiring a public key of a target node matched with the authority information of the student identity information;

step 404: encrypting the student identity information of the target user through the public key of the target node to obtain encrypted student identity information;

step 405: and generating a target block based on the user identification, the data authority information and the encrypted student identity information corresponding to the student identity information, and adding the target block into the block chain network.

Therefore, the cochain storage of the student identity information can ensure the fairness and justice of the student identity information and cannot be falsified due to the fact that the block chain network cannot be modified.

In some embodiments of the invention, the method further comprises: receiving data synchronization requests of other mechanism nodes in the block chain network; verifying the authority of the other organization nodes in response to the data synchronization request; and when the authority of the other mechanism nodes passes the verification, controlling the current mechanism node and the other mechanism nodes to carry out data synchronization. Because other mechanism nodes in the blockchain network cannot acquire the student identity information uploaded by the current mechanism node, when the other mechanism nodes in the blockchain network expect to acquire the corresponding student identity information, corresponding data synchronization requests need to be sent out; taking the user's learning as an example, when the user learns from the current organization to any other organization, the blockchain network management platform may verify the authority of the other organization node according to the received data synchronization request; when the authority of the other mechanism nodes passes the verification, the current mechanism node and the other mechanism nodes are controlled to perform data synchronization (for example, data synchronization can be performed in a mode that the other mechanism nodes and the current mechanism node agree with each other), so that the integrity of the transmission of the student identity information between the different mechanism nodes is ensured.

In some embodiments of the present invention, when the management authority of other mechanism nodes in the blockchain network needs to be adjusted, with reference to the student identity information processing method in the blockchain network shown in fig. 4, continuing with fig. 5, fig. 5 is an optional flowchart of the student identity information processing method in the blockchain network provided in the embodiment of the present invention, where the processing procedure includes the following steps:

step 406: the student identity information processing device receives management authority adjustment requests of other organization nodes in the block chain network;

step 407: responding to the management authority adjustment request, and verifying the authority of the other organization nodes;

step 408: judging whether the authority of other organization nodes passes the verification, if so, executing a step 409, otherwise, executing a step 410;

step 409: and when the authority of the other organization nodes passes the verification, adjusting the management authority of the other organization nodes.

Therefore, new blocks are added in the block chain network through the other mechanism nodes to update the student identity information of the target user.

Step 410: and maintaining the management authority of the current organization node.

Taking the user's learning as an example, when the user learns from the current organization to any other organization, the blockchain network management platform may verify the authority of the other organization node in response to the received management authority adjustment request; when the authority of the other organization node passes the verification (namely the user's ascending education organization is correct), the management authority of the other organization node is adjusted, and the other organization node which obtains the management authority can continuously add and/or adjust the student identity information stored in the blockchain network. On the contrary, when the authority of the other organization node is not verified (namely, the user's ascending organization goes wrong), the user data is continuously managed by the current organization node.
