All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to reduce the possibility of wrong identification and resolution of a digital object, embodiments of the present invention provide a method for managing an industrial internet digital object based on a block chain.
The block chain-based industrial internet digital object management method provided by the embodiment of the invention can be applied to an identification analysis secondary node of an industrial internet, and the identification analysis secondary node can comprise a plurality of first servers and at least one second server. In a specific application, each first server may be composed of one or more server hardware devices, and each second server may also be composed of one or more server hardware devices.
In the embodiment of the invention, a plurality of block chains are associated with the identification analysis secondary node, each block chain is used for storing operation records aiming at one type of information of a digital object, and different block chains correspond to different types of information; each operation record comprises an identifier of a digital object, an operation instruction for information of the digital object and generation time of the operation record; and each first server for identifying the analysis secondary node is added into at least one block chain in the block chains, and each second server is added into the block chains associated with the identification analysis secondary node.
The first server can be built and managed by enterprises in a certain industry or region, and each enterprise can add the built and managed first server into a block chain related to the enterprise according to the needs of the enterprise; the second server can be built and managed by a construction unit of the identification analysis secondary node, and the second server is added into all block chains associated with the identification analysis secondary node, so that the identification analysis service of the digital object can be provided for the whole industrial internet. Therefore, the block chain-based industrial internet digital object management method provided by the embodiment of the invention can realize multi-party co-treatment. The multiple parties may include an enterprise that manages each first server, or may include an enterprise that manages each first server and a support unit that identifies the resolution secondary node.
In practical applications, in order to consider the efficiency of information entry and identifier resolution of a digital object, and also to ensure the security of the entered information and the credibility of the identifier resolution, a plurality of blockchains associated with the identifier resolution secondary node may be a federation chain. Here, a federation chain is a block chain, and is different from a case where any node in a public chain can join the public chain without authentication, in the federation chain, a newly joined node needs to join after authentication and identity issuance of a management node, and parties joining the federation chain form a profit-related federation and jointly maintain the block chain on the federation chain. Here, the node joining the federation chain corresponds to the first server and the second server of the embodiment of the present invention, and the management node of the federation chain corresponds to the third server described below.
First, a detailed description is given to a method for managing an industrial internet digital object based on a block chain according to an embodiment of the present invention, as shown in fig. 1, the method for managing an industrial internet digital object based on a block chain according to an embodiment of the present invention may include the following steps:
s101: when receiving an operation request for any digital object, the first server determines a target block chain matched with the operation request from the added one or more block chains.
The functions that can be realized by each first server in the identification analysis secondary node comprise: registration of digital objects and entry of information. In a specific application, when any first server receives an operation request for any digital object, corresponding processing is executed for the operation request.
Wherein, the operation request for any digital object may include: identification of the digital object and operation instructions for information of the digital object. Here, the operation instruction may specifically include a plurality of kinds. Illustratively, the operational instructions may include one or more of the following instructions:
an instruction to add an identification of a digital object, an instruction to modify an identification of a digital object, an instruction to delete a digital object, an instruction to add information of a digital object, an instruction to modify information of a digital object, and an instruction to delete information of a digital object.
In the embodiment of the invention, the information type corresponding to the operation record stored in the target block chain is matched with the information type operated by the operation instruction contained in the operation request. For example, assume that a first server adds 3 block chains, where the information type corresponding to block chain 1 is: an enterprise information system entry address; the information types corresponding to the block chain 2 are: enterprise website URL (Uniform Resource Locator); the information types corresponding to the block chain 3 are: the address of the smart device. When the first server receives an operation request for a digital object a, and an operation instruction included in the operation request is to modify an address of the smart device of the digital object a, the blockchain 3 is the target blockchain matched with the operation request. It will be understood that a is used herein to represent the identity of digital object a. In the embodiment of the present invention, the representation manner of the identifier of the digital object is not limited.
S102: and the first server takes the current time as the generation time to generate a target operation record, wherein the identifier and the operation instruction contained in the target operation record are respectively the same as the identifier and the operation instruction contained in the operation request.
Here, the implementation manner of generating the target operation record by the first server is similar to the existing manner of generating the transaction record on the blockchain, and specifically, the identifier and the operation instruction included in the operation request may be packaged as one transaction on the blockchain, that is, the operation record generated by the first server has the same or similar form as the transaction record on the blockchain.
S103: the first server broadcasts the target operation record to each first server and each second server joining the target block chain, so that the target operation record is identified and verified by each first server and each second server joining the target block chain.
It is understood that when the common identification verification of the first server and the second server added to the target block chain is passed, the target operation record is stored in the target block chain. And when the target operation record is identified and verified as not passing by the first server and the second server which are added into the target block chain, the target operation record cannot be stored into the target block chain.
In practical applications, each server joining the target block chain is responsible for collecting operation records broadcast by each first server joining the target block chain in turn, and the collected operation records are packed into a block, and the block is sent to each first server and each second server joining the target block chain. After each first server and each second server receive the block, the operation records on the block are subjected to consensus verification by using a consensus algorithm, and when the verification result passes, the block can become a formal block on the target block chain. In the prior art, consensus algorithms are used to solve the problem of how to reach a resolution for each server joining a blockchain. In the embodiment of the present invention, the consensus algorithm may adopt a PBFT (Practical Byzantine Fault Tolerance) algorithm or a raft (replicated and Fault Tolerance) algorithm, but is not limited thereto. Here, RAFT is an existing distributed consensus algorithm. It is understood that, so-called consensus verification, each server participating in verification can obtain a verification result that is verified only when the verification results of all the servers joining the blockchain are passed, or the verification results of most of the servers joining the blockchain are passed.
As can be seen, the functions that can be implemented by each first server in the identification resolution secondary node may further include: and participating in consensus verification of operation records on the added blockchain. Identifying the functionality implemented by each second server in the resolution secondary node may include: and participating in the consensus verification of the operation records on the plurality of block chains associated with the identification resolution secondary node.
S104: and the second server synchronizes the operation records from the block chains according to a preset period, classifies the synchronized operation records according to the identification, and sequentially executes the operation instructions contained in the group of operation records according to the generation time aiming at each group of operation records obtained by classification to obtain a group of operation results corresponding to the group of operation records.
It can be understood that, since the operation records stored in the blockchain belong to the process information, after the operation records are synchronized from the plurality of blockchains and are classified, the second server executes the operation instruction in each group of operation records obtained by classification, so as to obtain a group of operation results, where the group of operation results corresponds to the identifier of the same digital object. For example, assume that the operation instructions in the categorized set of operation records include: the smart device address for newly added digital object a is 192.168.1.0, the smart device address for modified digital object a is 192.168.1.1, and the smart device address for modified digital object a is 192.168.1.3. Then the operation result corresponding to the operation record is: the smart device address for digital object a is 192.168.1.3. Of course, a set of operation results corresponding to each set of operation records may include various information of the digital object, and is not limited to the smart device address shown here.
S105: and when the second server receives an analysis request for the identifier of any digital object, searching a group of operation results corresponding to the identifier contained in the analysis request from the obtained operation results.
Here, the resolution request for the identification of any digital object may include the identification of the digital object.
S106: the second server takes the searched operation result as analysis information; and taking the analysis information as the analysis result of the identifier contained in the analysis request.
It is to be understood that the functions that can be implemented by each second server in the identification resolution secondary node may further include: the identification of the digital object is parsed. In a specific application, when any second server receives a resolution request for the identifier of any digital object, corresponding processing is executed for the resolution request.
In the embodiment of the invention, the first server executes S101-S103 to realize the processing of the operation request of the digital object; the second server executes S104 to realize the synchronization and integration processing of the operation records; the second server performs S105-S106 to implement the processing of the parsing request for the digital object. In practical application, the processing of the operation request of the first server to the digital object, the synchronization and integration processing of the operation record by the second server, and the processing of the analysis request of the second server to the digital object may be parallel, and no absolute precedence relationship exists.
The management method of the block chain-based industrial internet digital object is applied to an identification analysis secondary node of the industrial internet, and the identification analysis secondary node comprises a plurality of first servers and at least one second server. In the method, a plurality of block chains are used for storing information of the digital object, wherein a first server joins at least one block chain, and a second server joins all the block chains. For any digital object operation request, the operation record is stored in the target block chain only after the mutual identification verification of the operation record by each first server and each second server added to the target block chain is passed. Thus, the information of the digital object can be effectively prevented from being tampered. The information type corresponding to the operation record stored in the target block chain is matched with the information type operated by the operation instruction contained in the operation request. The second server can synchronize the operation records on all the block chains and classify the synchronized operation records according to the identifiers; and sequentially executing the operation instructions contained in the group of operation records according to the generation time aiming at each group of operation records obtained by classification to obtain a group of operation results corresponding to the group of operation records. Here, each set of operation results is information of one digital object. When the second server analyzes the identifier of the digital object, the analyzed information comes from the block chain commonly maintained by each first server, so the method can ensure the credibility of the identifier analysis of the digital object.
On the basis of the management method of the block chain based industrial internet digital object shown in fig. 1, another management method of the block chain based industrial internet digital object is further provided in an embodiment of the present invention, as shown in fig. 2, the method may include the following steps:
s2: when receiving an operation request for a digital object, a first server judges whether a target block chain matched with the operation request exists or not; if the judgment result is negative, the step is shifted to S201; if the determination result is yes, the process proceeds to S211.
Here, there are various specific implementation manners in which the first server determines whether there is a target block chain matching the operation request. For example, in an implementation manner, a respective information type matching table may be pre-established in each first server, and the matching table records the type of information corresponding to the blockchain added by the first server. When the information operated by the operation instruction contained in the operation request can be matched with any one of the information recorded in the matching table, the first server judges that a target block chain matched with the operation request exists; when the information operated by the operation instruction contained in the operation request cannot be matched with any information recorded in the matching table, the first server judges that the target block chain matched with the operation request does not exist.
S201: the first server sends the operation request to each second server respectively.
S202: when the second server receives an operation request sent by any first server, the second server updates the information of the digital object corresponding to the identification in the local information base according to the digital object identification and the operation instruction of the information of the digital object contained in the received operation request.
Here, there are various specific implementation manners in which the second server updates the information of the digital object corresponding to the identifier in the local information base according to the digital object identifier included in the received operation request and the operation instruction for the information of the digital object. For example, in one implementation, the second server may execute the operation instruction included in each operation request when receiving the operation request, and store the execution result in the information packet corresponding to the target identifier in the local information base. Here, the target identifier is an identifier included in the operation request, and various information of the digital object corresponding to the target identifier may be stored in the information packet corresponding to the target identifier. It is understood that the information stored in the information packet corresponding to the target identifier is the execution result of the operation instruction, and belongs to the result information, not the process information.
It is understood that S201-S202 may implement the down-link processing of operation requests for digital objects. Here, the down-link processing refers to processing of an operation request for a digital object that is realized without passing through a block chain. In practical applications, the downlink processing manner shown in S201-S202 may be the same as the manner of processing the operation request for the digital object in the existing identifier resolution secondary node, and the present invention is not described again.

Based on the above embodiments, it can be seen that, by using the method for managing digital objects of the industrial internet based on the blockchain according to the embodiments of the present invention, besides the types of information that can be stored in the blockchain, more types of information can be stored. Thereby making the information identifying the digital object parsed by the parsing secondary node richer.
In addition, in an implementation manner, identifying the parsing secondary node may further include: a third server; correspondingly, the method for managing the block chain-based industrial internet digital object provided by the embodiment of the invention further comprises the following steps:
and when receiving a registration application which is applied to become the first server or the second server by any server, the third server verifies the registration application, issues an identity certificate for the first server or the second server which is successfully registered when the registration application passes the verification, and broadcasts identity information of the first server or the second server which is successfully registered to the first server and the second server which are already provided by the identity resolution secondary node.
The registration application may include: applying for information of a first server or a second server, and applying for a block chain to be added when the server becomes the first server; the identity information may include: the server is information of the first server or the second server, and the block chain added when the server is the first server.
It can be understood that, when the third server receives a registration request for any server to become the first server or the second server, if the software and hardware conditions of the server meet the requirements of the first server or the second server, the third server may issue an identity certificate for the first server or the second server, and broadcast the identity information of the server to the first server and the second server existing in the identity resolution secondary node; if the software and hardware conditions of the server do not meet the requirements of the first server or the second server, the third server can reject the application of the server.
In practical applications, the third server may be built and managed by a contractor that identifies the resolution secondary node. It can be understood that the third server does not affect the operation of the first server and the second server that have joined the blockchain when processing the registration request of the server.
The third server may also perform other management tasks in addition to the task of processing the server registration request. For example, the third server may associate a new blockchain for the identity resolution secondary node, discard an invalid blockchain, select a consensus algorithm for the new blockchain, monitor the blockchain associated with the identity resolution secondary node, and so on.
Based on the foregoing embodiments, it can be seen that in the method for managing an industrial internet digital object based on a block chain according to the embodiments of the present invention, a third server may be used to manage and monitor the first server and the second server in the identifier resolution secondary node and the block chain associated with the identifier resolution secondary node.
In addition, in practical application, one or more software modules can be installed in the server hardware equipment to build the identification analysis secondary node. Illustratively, in an implementation manner, when building the identifier resolution secondary node, the following software modules may be used:
the system comprises a Handle system module, a demand processing module, a chain state control module, a consensus accounting module and a trusted storage module.
The Handle system module can adopt a software module for managing, identifying and analyzing the secondary node in the existing Handle system. The Handle system is an existing service system for managing digital objects in the industrial internet. The Handle system module faces the industrial Internet and provides analysis requests for the digital objects. And the Handle system module is also used for realizing the down-link processing of the operation request of the digital object. The chain state control module is used for managing and monitoring a first server and a second server in the identification analysis secondary node and a block chain related to the identification analysis secondary node. The consensus accounting module is used for realizing uplink processing of the operation request of the digital object, namely generating an operation record according to the operation request and storing the operation record into the block chain. The trusted storage module is used for synchronizing the operation records from the block chain, classifying the synchronized operation records and integrating the operation records into the information of the digital object, so that the Handle system module can access the integrated information when processing the analysis request of the digital object. The demand processing module is used for distinguishing whether the operation request for the digital object has a target block chain or not according to the information type matching table, and correspondingly transferring the operation request to the Handle system module for processing or to the consensus accounting module for processing.
Specifically, when the identifier resolution secondary node is built, a demand processing module and a consensus accounting module can be installed in the first server; the second server can be provided with a consensus billing module, a trusted storage module and a Handle system module; the third server may install a chain state control module.
In practical applications, the software module may be an existing software module, or may be a self-developed software module. It can be understood that after various functions that can be realized by the identification analysis secondary node are respectively packaged into software modules, the identification analysis secondary node can be easily built only by installing corresponding software modules in the server hardware equipment. In addition, it is understood that the software modules installed in the first server and the second server may communicate with each other, so as to cooperatively perform various functions that the servers can implement. For example, in the first server, when the demand processing module transfers the operation request to the consensus accounting module for processing, it needs to initiate an application to the consensus accounting module, and accordingly, after receiving the application, the consensus accounting module feeds back the consensus accounting result to the demand processing module. In the second server, the trusted storage module may send a timed interaction request to the consensus accounting module, and correspondingly, after receiving the interaction request, the consensus accounting module feeds back an operation record to the trusted storage module; and when the Handle system module provides the identification analysis service, sending a query request to the trusted storage module, and correspondingly, after receiving the query request, feeding back a query result to the Handle system module by the trusted storage module. In addition, the local information base in the second server can permit the Handle system module to access, so that when the Handle system module provides the identification analysis service, on one hand, the information of the digital object is inquired from the trusted storage module, on the other hand, the information of the digital object is inquired from the local information base, and the inquiry result of the two aspects is used as analysis information to be fed back to a sender of the analysis request.
