Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. 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 application.

At present, when each enterprise stores its corresponding business data on a blockchain, based on the characteristics of blockchain decentralization, some inevitable enterprises need to privately deploy blockchain services in their respective network environments, and when there are multiple enterprises that privately deploy blockchain services in their respective network environments and form a network, how to manage control data among them is a problem that needs to be considered. In the prior art, the management and control data corresponding to the business object is usually stored and managed by using a database, for example, the database may be a mySQL database, and the manner of storing and managing the management and control data has no synchronization mechanism, that is, data synchronization cannot be realized between the management and control data corresponding to each enterprise.

For example, as shown in fig. 1a, which is a schematic flow diagram of implementing an operation of adding new data for each enterprise provided in the prior art, when data is added to a service blockchain network for each enterprise, service nodes are already established between an enterprise a and an enterprise B, where the service node of the enterprise a is node a, the service node of the enterprise B is node B, and the node a and the node B form a service blockchain network. Then, when the enterprise a and the enterprise B add new data at the same time, as shown in fig. 1a, taking the added data as an example for explanation, a specific implementation process may include the following steps:

s1: enterprise a needs to add a contract, the contract name is mycc, at node a, and then a contract creating request may be sent to the management and control device.

s2: after receiving the contract creation request, the management device saves the contract mycc carried in the contract creation request into a management and control database a, wherein the management device is a device for providing management and control services.

s3: after the management and control database a stores the contract mycc, the management device sends the contract mycc to the node a again, so that the node a instantiates the contract mycc, and then, after receiving the contract mycc, the node a may execute the following steps s3.1 to s3.3.

s3.1: after node a receives the contract mycc, the contract mycc is instantiated.

s3.2: after successful instantiation of the contract mycc, the contract mycc is broadcasted to other nodes in the service block chain network so as to realize data synchronization between the node A and the node B.

s3.3: after receiving the contract mycc broadcast by node a, node B stores the contract mycc on its own maintained block chain.

s4: after enterprise a needs to add a new contract mycc at node a, the governing device also receives a contract creation request sent by enterprise B, and the contract name is also mycc.

s5: after receiving the contract creation request, the management device saves the contract mycc carried in the contract creation request into the management and control database B.

s6: after the contract mycc is stored in the management and control database B, the management device sends the contract mycc to the node B, so that the node B instantiates the contract mycc, but the existence of a contract with the same name on a block chain maintained by the node B is detected during instantiation, the contract with the same name is broadcast to the node B by the node a, and then when the existence of the contract with the same name is detected by the node B, an error is reported, and the node B does not perform subsequent operations on the contract mycc to be newly added.

It can be known from the above description that the enterprise a deploys and instantiates a contract on the service blockchain network through the management and control device, and since the management and control database of the enterprise B does not have the record with the contract name of mycc, that is, the enterprise a stores the contract in the management and control database, and does not synchronize the data of the stored contract with the management and control database of the enterprise B, the enterprise B does not report an error when storing the contract with the name of mycc in the management and control database through the management and control device, and the node B corresponding to the enterprise B reports an error when instantiating the contract, so that the enterprise B needs to redeploy a new contract, thereby reducing the data management efficiency and also leading to poor user experience. Then, in order to implement synchronization of management data, it is currently common to deploy an external component at each network node, or design a synchronization service by an enterprise respectively. Both methods can ensure that the required data is synchronized in the network, but both methods bring additional problems, for example, when each network node deploys an external component, the external component needs to be introduced, and the enterprise designs a synchronization service respectively, which also increases the development and operation cost.

In view of the foregoing problems, an embodiment of the present application provides a data management method based on a block chain, where the method is executable by a management and control device for providing a management and control service, and a general principle of the method is as follows: the management and control device may receive a management request of a target service object for the management and control data to be processed, where the management request indicates a management type for the management and control data to be processed, and then, the management and control device performs, in a management and control block chain corresponding to the management and control block chain network, update processing matched with the management type on the management and control data to be processed through a target management and control node corresponding to the target service object, and then, according to a processing result of the update processing, sends management indication information associated with the management and control data to be processed to the target service node corresponding to the target object, where the management indication information is used to indicate the target service node to perform target management on the management and control data to be processed according to an indication of the management indication information. By implementing the method, the management and control blockchain network is introduced, so that the management and control data can be updated by using the management and control blockchain network, the updated management and control data can be synchronized to other management and control nodes in the management and control blockchain network based on the data synchronization characteristic of the blockchain, the automatic synchronization of the management and control data is realized, an external component is not required to be introduced, the additional cost can be reduced, and the data management efficiency is improved.

Referring to fig. 1b, fig. 1b is a schematic structural diagram of a data management system based on a blockchain according to an embodiment of the present disclosure, where the data management system based on a blockchain includes a management and control device 10, a service blockchain network 11, and a management and control blockchain network 12. The management and control device 10 may be configured to provide a management and control service, the service blockchain network 11 may include service nodes 13 corresponding to a plurality of service objects, and the management and control blockchain network 12 may include management and control nodes 14 corresponding to a plurality of service objects, where any one of the management and control nodes 14 is configured to store management and control data of a corresponding service object and synchronize the management and control data to other management and control nodes 14 in the management and control blockchain network, and the service node and the management and control node corresponding to any one of the service objects are deployed in the same network environment. The business object can be an enterprise, such as enterprise 1, enterprise 2, enterprise 3, etc., it being understood that each business node in a business blockchain network is a blockchain node created by the respective enterprise, the business node being a business node that provides business services for the enterprise. It should be noted that one service object may create one service node, or may create multiple service nodes, and the multiple service nodes are deployed in multiple service block chain networks. Then, for an enterprise, the aforementioned management and control data may include information about service nodes created by the enterprise, for example, the number of service nodes created by the enterprise, the name of the service blockchain network in which each service node is located, data stored by each service node, for example, the data may be contracts deployed in the service nodes, and the like.

For example, regarding any enterprise, fig. 1c is a schematic structural diagram of another data management system based on a blockchain according to an embodiment of the present disclosure, where fig. 1c may be a data management system based on a blockchain deployed in a network environment of an enterprise a, it is assumed that a node 1 in a control blockchain network is a control node corresponding to the enterprise a, and a node 11 in a service blockchain network 1 and a node 21 in a service blockchain network 2 are all service nodes corresponding to the enterprise a, and as can be seen from fig. 1c, a control device, a control node corresponding to the enterprise a, and a service node are all in the network environment of the enterprise a. The management and control device may be a device for providing various services, for example, a management and control service, a Web service, or other services, and may further include a database for storing various data, for example, management and control data, or other data, and may further include a console for providing a user operation page for a user to input a management request, and the user may manage the management of the control blockchain network or the service blockchain network through the user operation page, including addition management, deletion management, modification management, creation and instantiation of a contract, and the like. The block chain service privatization management and control service can pack functions of a console contained in a management and control device together onto a physical machine for automatic deployment, so that the management and control device can be used for providing the management and control service. The management and control device may be a terminal or a server, which is not limited in this application. The terminal may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, and the like. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, middleware service, a domain name service, a security service, a CDN, a big data and artificial intelligence platform, and the like.

The management and control device 10 is configured to receive a management request of a target service object for management and control data to be processed, where the management request indicates a management type for the management and control data to be processed, and the management type may include a new data type, a deleted data type, and a modified data type. After the management and control device receives the management data, the target management and control node corresponding to the target service object may be accessed, update processing matched with the management type is performed on the management and control data to be processed in the management and control block chain corresponding to the management and control block chain network, and further, according to a processing result of the update processing, management indication information associated with the management and control data to be processed is sent to the target service node corresponding to the target object, where the management indication information is used to indicate the target service node to perform target management on the management and control data to be processed according to an indication of the management indication information.

And the target management and control node 14 is configured to receive a management request sent by the management and control device, execute, according to the management request, update processing matched with the management type on the to-be-processed management and control data in a management and control block chain corresponding to the management and control block chain network, and send a processing result of the update processing to the management and control device, so that the management and control device sends, according to the processing result of the update processing, management indication information associated with the to-be-processed management and control data to a target service node corresponding to a target service object.

And the target service node 13 is configured to receive management instruction information, which is sent by the management and control device and is associated with the management and control data to be processed, and execute target management on the management and control data to be processed according to an instruction of the management instruction information.

It should be noted that the number of nodes shown in fig. 1b is only illustrative, and any number of nodes may be deployed according to actual needs.

Each node in the blockchain network (which may be understood as the above-mentioned managed blockchain network or the service blockchain network) has a node identifier corresponding thereto, and each node in the blockchain network may store node identifiers of other nodes in the blockchain network, so that the generated block is broadcast to other nodes in the blockchain network according to the node identifiers of other nodes in the blockchain network. Each node may maintain a node identifier list as shown in table 1, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an Internet Protocol (IP) address or any other information that can be used to identify the node, and the table is described by taking the IP address as an example. For example, table 1 maintains a list of node identities for node 1, so when node 1 generates a new tile, the new tile may be broadcast to other nodes in the blockchain network according to the node identities of the respective nodes in table 1.

TABLE 1

Node name	Node identification
		Node 1	117.114.151.174
Node 2	117.116.189.145
		…	…
Node N	119.123.789.258

Each node in the blockchain network stores one identical blockchain. The block chain is composed of a plurality of blocks, as shown in fig. 1d, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

When each block in the block chain is generated, referring to fig. 1e, when a node where the block chain is located receives input information, the input information is verified, after the verification is completed, the input information is stored in a memory pool, and a hash tree used for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET

wherein SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block header characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value within a period of time, and is determined again after the fixed period of time is exceeded; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the block chain network where the newly generated blocks are located according to the node identifications of the other nodes in the block chain network, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.

The implementation details of the technical solution of the embodiment of the present application are set forth in detail below:

referring to fig. 2, fig. 2 is a schematic flowchart of a block chain-based data management method provided in an embodiment of the present application, where the block chain-based data management method relates to a service block chain network, a management control block chain network, and a management control device, and this embodiment mainly describes an interaction process among the service block chain network, the management control block chain network, and the management control device, and the block chain-based data management method includes the following steps:

s201: and the management and control equipment receives a management request of the target business object for the to-be-processed management and control data.

In a possible embodiment, the management and control device may receive a management request of the target business object for the management and control data to be processed. The management and control device can provide a user operation interface and display the user operation interface on a user terminal interface, and when a user needs to manage the management and control data in the management block chain network, for example, when data is added or deleted or data is modified or data is searched, the user can send a management request through the user operation interface. The user operation interface can comprise a first area and a second area, and the first area can comprise a management type setting item, a request information setting item and a confirmation control. Specifically, the user operation interface may be as shown in fig. 3a, the first area may be as shown in the first area marked by 31 in fig. 3a, and the first area may include a management type setting item, a request information setting item, and a confirmation control, where the management type setting item may include finding, adding, deleting, and modifying, the request information setting item may include a management object, where the management object may be related information used to input management and control data to be processed, and the user operation interface may also include other information, which is not limited in this application.

In a possible embodiment, after the management and control device detects that the confirmation control as in fig. 3a is triggered, a management request may be generated based on the management type set at the management type setting item and the request information set at the request information setting item, that is, the management and control device may receive a management request of the target business object for the management and control data to be processed, so as to perform the subsequent steps.

S202: and the management and control equipment sends a management request to a target management and control node corresponding to the target service object.

In a possible embodiment, the management and control device may send a management request to a target management and control node corresponding to the target service object. Optionally, if the management and control device is a device corresponding to the target service object, that is, the management and control device only provides the management and control service for the target service object, the management and control device may directly send the management request to the target management and control node corresponding to the target service object. For example, if the target business object is enterprise a, that is, the management and control device provides management and control services only for enterprise a, the management and control device may directly send the management request to the target management and control node corresponding to enterprise a. Optionally, if the management and control device may provide management and control services for multiple service objects, the management request received by the management and control device may also carry the target identifier. The target identifier may be an identifier of a target service object, or an identifier of a target management and control node, or other identifiers that may be used to indicate the target management and control node. After the management and control device receives the management request, a target management and control node corresponding to the target service object may be determined according to the target identifier carried in the management request, and the management request is sent to the target management and control node. For example, if the target service object is an enterprise a, that is, the management and control device may provide management and control services for the enterprise a, the enterprise B, and the enterprise C, then the management request received by the management and control device may carry a target identifier for indicating a target management and control node corresponding to the enterprise a, so that the management and control device sends the management request to the target management and control node corresponding to the enterprise a according to the target identifier.

S203: and the target control node executes updating processing matched with the management type on the control data to be processed in the control block chain corresponding to the control block chain network according to the management request.

In a possible embodiment, after the target management and control node receives the management request sent by the management and control device, the update processing matching the management type may be performed on the management and control data to be processed in the management and control blockchain corresponding to the management and control blockchain network according to the management request. The management type may include a search data type, an add data type, a delete data type, and a modify data type. For example, when the management type is a lookup data type, the update process performed on the managed data to be processed, which matches the lookup data type, may be the number of service nodes created by the lookup target service object, or the name of the service block chain network where each service node is located, or the like. For another example, when the management type is a new data type, the pending management data for which the management request is directed may be a contract, and then, performing update processing on the pending management data matching the lookup data type may be adding the contract to a management block chain corresponding to the management block chain network. For another example, when the management type is a delete data type, the pending management data for which the management request is directed may be a contract, and then performing update processing on the pending management data that matches the delete data type may be deleting the contract from a management block chain corresponding to the management block chain network. For another example, when the management type is a modified data type, the pending management data for which the management request is directed may be a contract, and then performing update processing on the pending management data that matches the modified data type may be modifying a name of the contract in a management block chain corresponding to the management block chain network.

S204: and the target management and control node returns the processing result of the updating processing to the management and control equipment.

In a possible embodiment, when the target management and control node performs the update process matching the management type on the management and control data to be processed, two types of process results may also occur, and the process results may include a process result indicating that the update is successful and a process result indicating that the update is failed. The processing result can be displayed on the user operation interface, so that the user can determine whether the management request is successfully executed according to the processing result displayed on the user operation interface. Then, the user operation interface may further include a second area, which may be a display area for managing a processing result corresponding to the device return management request, as shown by an area marked by 32 in fig. 3 a.

For example, when the target management and control node receives that the management type in the management request is the query data type, if the target management and control node may query target management and control data corresponding to the management and control data to be processed in the management request, the target management and control node may send the queried target management and control data to the management and control device, and after receiving the target management and control data, the management and control device may display the target management and control data in the second area of the user operation interface. If the target management and control node cannot query the target management and control data corresponding to the management and control data to be processed in the management request, the target management and control node may return a query failure result to the management and control device, and after receiving the query failure result, the management and control device may display the query failure result in the second area of the user operation interface.

For another example, when the target management and control node receives that the management type in the management request is a delete data type, if the target management and control node can delete the target management and control data corresponding to the management and control data to be processed in the management request, the target management and control node may return a successful deletion result to the management and control device, and after receiving the successful deletion result, the management and control device may display the successful deletion result in the second area of the user operation interface. If the target management and control node does not delete the target management and control data corresponding to the management and control data to be processed in the management and control request, the target management and control node may return a deletion failure result to the management and control device, and after receiving the deletion failure result, the management and control device may display the deletion failure result in the second area of the user operation interface.

S205: and the management and control equipment sends management indication information associated with the to-be-processed management and control data to the target service node corresponding to the target service object according to the processing result of the updating processing.

S206: and the target service node executes target management on the to-be-processed management data according to the indication of the management indication information.

In step S205 and step S206, after the management and control device receives the processing result of the update processing sent by the target management and control node, management indication information associated with the management and control data to be processed may be sent to the target service node corresponding to the target service object according to the processing result of the update processing, so that the target service node performs target management on the management and control data to be processed according to the indication of the management indication information. The management and control device may send the management instruction information to the target service node when the processing result received by the management and control device is the processing result indicating that the update is successful. Specifically, after receiving the processing result of the update processing, the management and control device may detect whether the processing result is a processing result indicating that the update is successful, and send management indication information to the target service node if it is detected that the processing result is a processing result indicating that the update is successful.

In a possible embodiment, if the management type is a new data type, when the target management and control node writes the to-be-processed management and control data to which the management request is directed into the management and control block chain, the management and control device may return a new processing result indicating that the to-be-processed management and control data is successfully added. And after the control device receives the new processing result, new indication information associated with the control data to be processed is sent to the target service node corresponding to the target service object. Then, after receiving the management indication information, the target service node may perform new addition management on the to-be-processed management data in the service block chain according to the indication of the management indication information. For example, if the to-be-processed management and control data is a target contract, the new addition management may be to instantiate the target contract, that is, the target service node instantiates the target contract in the service block chain.

In a possible embodiment, if the management type is a delete data type, and the deletion processing result received by the management and control device indicates that the deletion of the managed data to be processed is successful, the management and control device may send deletion indication information associated with the managed data to be processed to the target service node corresponding to the target service object, and after the target service node receives the deletion indication information, the deletion management may be performed on the managed data to be processed in the service block chain according to an indication of the deletion indication information. For example, if the pending management and control data is a target contract, the deletion management may be to delete the target contract, that is, the target service node deletes the target contract in the service block chain.

In a possible embodiment, if the management type is a modified data type, and the modification processing result received by the management and control device indicates that the management and control data to be processed is successfully modified, the management and control device may send modification indication information associated with the management and control data to be processed to a target service node corresponding to a target service object, and after the target service node receives the modification indication information, perform modification management on the management and control data to be processed in a service block chain according to an indication of the modification indication information. For example, if the pending management and control data is a target contract, the modification management may be to modify the target contract, where the specific modification to the target contract may be to modify the name of the target contract, that is, the target service node modifies the name of the target contract in the service block chain.

In a specific implementation scenario, the following description is given by taking an example that an enterprise a and an enterprise B both need to add new targets on their corresponding service nodes, as shown in fig. 3B, a schematic flow diagram for implementing an operation of adding new data by each enterprise provided in the embodiment of the present application is provided, and a specific implementation process of the schematic flow diagram may include the following steps:

s1: if the enterprise a needs to add a new target contract at the node a, where the name of the target contract is mycc, a management request may be sent to the management and control device, and the management type of the management request is a new data type.

S2: after receiving the management request, the management device may send the management request to the management and control node A1 corresponding to the enterprise a, so that the management and control node A1 performs, according to the management request, update processing matching the management type on the management and control data to be processed in the management and control blockchain corresponding to the management and control blockchain network, and then after receiving the target contract mycc, the node a may perform the following steps S2.1 to S2.2.

S2.1: after the management node A1 receives the management request, it may be queried in the management block chain according to the management request whether a contract exists that is the same name as the target contract.

S2.2: if the management and control node A1 inquires in the management and control block chain that a contract with the same name as the target contract exists, a newly added processing result for indicating that the newly added management and control data to be processed fails may be returned to the management and control device, where the newly added processing result may be for indicating that a contract with the same name exists. If the management and control node A1 inquires in a management and control block chain that no contract with the same name as the target contract exists, writing the target contract into the management and control block chain, wherein writing into the management and control block chain can be understood as that the management and control node A1 saves the target contract into the management and control node A1, and broadcasting the target contract to other management and control nodes in a management and control block chain network, that is, the management and control node B1 receives the target contract and stores the target contract, so that data synchronization between the management and control nodes is realized. The control node A1, in addition to writing the target contract into the control block chain, may also return a new processing result indicating that the target contract is successfully added to the control device.

S3: after the control device receives a new processing result returned by the control node A1 and used for indicating that a target contract is successfully added, that is, after the control node A1 successfully stores the target contract, the control device may send new indication information associated with the target contract to the service node A2, so that the service node A2 performs new management on the target contract in a service block chain according to the indication of the new indication information, where the new management may be instantiation of the target contract. Then, after receiving the new indication information, the service node A2 may perform the following steps S3.1 to S3.2.

S3.1: the target contract is instantiated.

S3.2: and after the target contract is successfully instantiated, broadcasting the target contract to other service nodes in the service block chain network so as to realize data synchronization between the service node A2 and the service node B2.

S3.3: service node B2, after receiving the target contract broadcast by service node A2, stores the target contract on its own maintained block chain.

S4: when enterprise a instantiates a target contract at service node A1 and enterprise B also instantiates the target contract at service node B2, enterprise B may send a management request to the managing device.

S5: after receiving the management request, the management device may send the management request to the management node B1 corresponding to the enterprise B, so that the management node B1 performs, according to the management request, update processing matching the management type on the to-be-processed management and control data in the management and control blockchain corresponding to the management and control blockchain network, and then, after receiving the target contract mycc, the node B may perform the following steps S5.1 to S5.2.

S5.1: after the management node B1 receives the management request, it may be queried in the chain of management blocks whether there is a contract with the same name as the target contract according to the management request.

S5.2: if the management and control node B1 inquires in the management and control block chain that a contract with the same name as the target contract exists, a newly added processing result indicating that the newly added management and control data to be processed fails may be returned to the management and control device, where the newly added processing result may be used to indicate that a contract with the same name exists. And if the control node B1 inquires that no contract with the same name as the target contract exists in the control block chain, writing the target contract into the control block chain, and returning a newly-increased processing result for indicating the successful newly-increased target contract to the control equipment. According to the above description, it is known that the management and control node B1 may query that a contract with the same name as the target contract exists in the management and control block chain, and then the management and control node B1 may return a new processing result indicating that the target contract fails to be newly added to the management and control device, where the new processing result may specifically indicate that a contract with the same name exists.

It can be seen that, compared with the situation that a synchronization mechanism does not exist between the management and control data as shown in fig. 1a, in the embodiment of the present application, synchronization of the management and control data can be achieved by using characteristics of the blockchain network, it can be determined whether a contract of the same name exists when a target contract is stored in the management and control blockchain network, if a contract of the same name exists, a processing result of a new failure can be returned to the management and control device, and it is not necessary to determine whether a synchronization contract exists during instantiation, and a processing result of a new failure is returned to the management and control device.

Referring to fig. 4, fig. 4 is a schematic flowchart illustrating another data management method based on a block chain according to an embodiment of the present disclosure.

Wherein the processing result of the update process may be displayed in the second area in the user operation interface, e.g. in the area marked by 31 in fig. 3 a.

Optionally, when the management type is the new data type, the target management and control node may first query, according to the to-be-processed management and control data in the management request, whether target management and control data associated with the to-be-processed management and control data exists in the management and control block chain. If the target management and control data associated with the management and control data to be processed is inquired in the management and control block chain, the target management and control node may return a new processing result for indicating that the new addition of the management and control data to be processed fails to the management and control device, and after receiving the new processing result for indicating that the new addition of the management and control data to be processed fails, the management and control device may further display the new processing result in the second area of the user operation interface. If the target control data associated with the control data to be processed is not queried in the control block chain, the target control node may write the control data to be processed into the control block chain, and return a new processing result indicating that the control data to be processed is successfully added to the control device, and after receiving the new processing result indicating that the control data to be processed is successfully added, the control device may further display the new processing result in the second area of the user operation interface.

Optionally, when the management type is the query data type, the target management and control node may query, in the management and control block chain, according to the to-be-processed management and control data in the management request, whether target management and control data associated with the to-be-processed management and control data exists. If the target management and control data associated with the management and control data to be processed is inquired in the management and control block chain, the target management and control data is returned to the management device, and after the management device receives the target management and control data, the target management and control data can be displayed in a second area of the user operation interface, so that a user can obtain required data. If the target management and control data associated with the management and control data to be processed are not queried in the management and control block chain, a query processing result used for indicating that the query of the target management and control data fails can be sent to the management device, and after the management device receives the query processing result used for indicating that the query of the target management and control data fails, the query processing result can be displayed in a second area of the user operation interface.

In a possible embodiment, after receiving the management request, the target management and control node may first detect whether the to-be-processed management and control data includes the private data identifier according to the management request, so as to perform subsequent steps according to the detection result. If it is detected that the to-be-processed management and control data includes the private data identifier according to the management request, the to-be-processed management and control data may be updated in the private management storage area of the target management and control node, where the update processing is matched with the management type, and the to-be-processed management and control data is prohibited from being synchronized to other management and control nodes in the management and control block chain network. If it is detected that the management and control data to be processed does not include the private data identifier according to the management request, the update processing matched with the management type may be performed on the management and control data to be processed in the private management storage area of the target management and control node, and the management and control data to be processed may be synchronized to other management and control nodes in the management and control block chain network. According to the method, whether the to-be-processed management and control data comprise the private data identification is detected, and then the subsequent steps are executed according to the detection result, so that the management and control data in the privacy management storage area of the target management and control node do not need to be synchronized to other management and control nodes in the management and control block chain network, the privacy isolation of the data corresponding to the target business object can be achieved, and the data safety of the target business object is guaranteed.
