The technical scheme provided by the embodiment of the application is described by a specific embodiment.
Because the method for creating entity portraits in the embodiment of the present application is applied to any node in a preset federation chain, the federation chain in the embodiment of the present application is described first.
The federation chain in the embodiment of the present application includes at least two nodes, where a node may be a server or a terminal device, as shown in fig. 1, which is a specific example diagram of the federation chain, including a node 1, a node 2, a node 3, and a shared pool formed by a plurality of blocks, where information sharing is performed between the node 1, the node 2, and the node 3 through the shared pool, and because the number of nodes is small, the node 1, the node 2, and the node 3 may communicate with each other. Of course, fig. 1 is only a specific exemplary diagram of a federation chain, and is not limited to the number of nodes in the federation chain, and the number of nodes in the federation chain may be adjusted in different situations.
In practical application, a multiparty organization forming the alliance constructs an alliance chain by taking a corresponding server or terminal device as a node, and a basic frame model of the alliance chain and validity specifications of data uploaded to the alliance chain by the node are formulated together. It can be seen that a federated chain is essentially a private blockchain, which can be understood as a database that is commonly created by multiple parties, through which information is shared, i.e., a shared database is co-built.
The basic framework model of the alliance chain comprises a data layer, a network layer, a consensus layer, a contract layer and an application layer.
The data layer encapsulates underlying data blocks, associated data encryption, and time stamps, etc., basic algorithms, such as blocks included in the basic data, digital signatures, hash functions, encryption algorithms, merkel trees, etc.
The network layer includes distributed networking mechanisms such as peer-to-peer (P2P), data propagation mechanisms such as message broadcasting, and data verification mechanisms such as transaction verification.
The consensus layer comprises various types Of consensus algorithms Of the network node, such as POW consensus algorithm (POW).
The contract layer comprises various scripts, algorithms and intelligent contracts, and is the basis of the programmable characteristics of the blockchain.
The application layer encapsulates application scenarios, such as distributed accounts book, data storage, API interface, etc. The alliance chain in the API interface application scene can provide a data access interface for nodes in the alliance chain and user terminals outside the alliance chain.
The application scenario of the method for creating entity portraits in the embodiment of the application can be a coalition chain created by a plurality of nodes together, each node in the plurality of nodes can broadcast the acquired entity information of one dimension of the entity to other nodes in the coalition chain, and also receive the entity information of at least one dimension of the entity broadcast by other at least one node, so that each node can acquire the entity information of a plurality of dimensions of the entity and create the entity portraits directly through the entity information of the plurality of dimensions.
Referring to fig. 2, a flow chart of a method for creating an entity portrait according to an embodiment of the present application is applied to any one node in a preset federation chain, where the federation chain includes at least two nodes, and the method includes:
step S201, the node acquires first entity information of a target entity of a portrait to be created.
Wherein, the node can be a server or a terminal device; the target entity may refer to an object that may be an entity index item, for example, a specific person (board of directors, supervisor or advanced manager) or a specific unit (company, school), and in addition, the target entity has a corresponding digital ID, and the node may confirm the target entity according to the digital ID carried in the first entity information; the first entity information is entity information of one dimension of the target entity.
By way of example and not limitation, taking the example that the target entity is a board of directors, the node may be a node corresponding to a marketing company, a node corresponding to a regulatory agency, or a node corresponding to a media agency, and the first entity information may be one of the following information: basic information (e.g., date of birth, age, academic, job title, social achievement, stock holding, etc.), character behavior information, corporate governance information, or social evaluation information (e.g., network evaluation), etc. It should be noted that the basic information, the character behavior information, the corporate governance information, and the social evaluation information all belong to entity information of one dimension of the board, where the corporate governance information is an influence result of the character behavior information, that is, entity information of multiple dimensions of the target entity has relevance.
In a specific application, if the node is a terminal device, a specific process of the node obtaining the first entity information of the target entity of the portrait to be created may be that the node receives the first entity information of the target entity of the portrait to be created directly input by a user.
If the node is a server, the specific process of the node obtaining the first entity information of the target entity of the portrait to be created may be that the node receives the first entity information of the target entity of the portrait to be created, which is sent by the user terminal.
In one possible implementation, since the federation chain is a private blockchain with a small number of nodes, the nodes can communicate with each other, and thus the consensus decision of a node in the federation chain can be essentially determined by a node trusted by most or all of the nodes, i.e., the federation chain includes a primary node and at least one secondary node. For example, in fig. 1, node 2 is a primary node, node 1 and node 3 are secondary nodes, then node 2 may directly determine that a new node joins the federation chain, and perform validity authentication on the data type, data format, data content, and the like of the new node according to the validity specification of the data of the federation chain.
Referring to fig. 3, a schematic flow chart before step S201 in fig. 2 for creating an entity representation according to an embodiment of the present application is shown, if a node is a master node, before the node obtains first entity information of a target entity for creating the representation, the method further includes:
step S301, the node acquires a link-in request of the node to be authenticated.
The node to be authenticated may be a server or a terminal device. It can be understood that before joining the federation chain, the node to be authenticated sends a chain request to the master node, and the chain entering request carries an identification code, so that the master node authenticates the node to be authenticated according to the chain entering request.
Step S302, the node responds to the link-in request and carries out link-in authentication on the node to be authenticated.
Specifically, after receiving a link-in request of a node to be authenticated, the node analyzes an identification code of the node to be authenticated from the link-in request, and authenticates whether the identity of the authentication node is in a local link-in member table according to the identification code, wherein the link-in member table can be set in advance.
Step S303, if the node confirms that the node to be authenticated passes the link-in authentication, the node to be authenticated is added into the alliance link as the secondary node.
It should be noted that, after the node to be authenticated is added as the secondary node to the federation chain, the master node performs validity authentication on the data type, the data format, the data content and the like of the node to be authenticated according to the validity specification of the data of the federation chain. Wherein the data types comprise business types such as business for creating entity portraits and entity types such as characters, the data formats comprise json formats, and the data contents comprise basic information, behavior information, social evaluation information and the like of the entities.
In one possible implementation manner, if the node confirms that the node to be authenticated passes the in-link authentication, the node to be authenticated is added into the alliance chain as the secondary node, and the method further includes:
the node generates member joining notification information corresponding to the node to be authenticated;
the node stores the member joining notification information to a local chain member database and sends the member joining notification information to each secondary node in the federation chain.
Wherein the member joining notification information includes membership such as a network address, a member joining time, and the like. It can be appreciated that after the node serving as the master node approves the node to be authenticated to join the federation chain, each secondary node in the federation chain is informed that a new member is added, so that each secondary node communicates with the newly added node to be authenticated.
Step S202, the node generates a first block according to the first entity information, and broadcasts the first block to other nodes in the alliance chain, wherein the other nodes are nodes except the node in the alliance chain.
Specifically, the node firstly acquires a chain tail block in the alliance chain, namely a block added into the alliance chain recently, wherein each block comprises a block head and a block main body; then, performing characteristic operation on the block head of the chain tail block to obtain a first characteristic value; then carrying out characteristic operation on the first entity information to obtain second characteristic information; and finally, generating a block head of the first block according to the first characteristic value and the second characteristic value, and generating a block main body of the first block according to the first entity information, thereby obtaining a complete first block.
In step S203, the node receives a second block broadcasted by at least one of the other nodes, and the second block is generated according to the second entity information of the target entity.
Each second entity information is entity information of one dimension of the target entity, in addition, the target entity has a corresponding digital ID, and the node can identify the target entity according to the digital ID carried in the second entity information.
Taking the example that the target entity is a board of directors, the node may be a node corresponding to a marketing company, a node corresponding to a supervision organization, or a node corresponding to a media organization, and the second entity information may be one of the following information: basic information (e.g., date of birth, age, academic, job title, social achievement, stock holding, etc.), character behavior information, corporate governance information, or social evaluation information (e.g., network evaluation), etc. It should be noted that the basic information, the character behavior information, the corporate governance information, and the social evaluation information all belong to entity information of one dimension of the board, where the corporate governance information is an influence result of the character behavior information, that is, entity information of multiple dimensions of the target entity has relevance.
Step S204, the node creates a portrait of the target entity according to the first entity information and the at least one second entity information.
The information content represented by the first entity information and the second entity information is different, and the information content represented by each second entity information is different.
It can be understood that each node can broadcast the acquired entity information of one dimension of the target entity to other nodes in the federation chain, and also receive the entity information of at least one dimension of the target entity broadcast by other at least one node, so that each node can acquire the entity information of multiple dimensions of the target entity, and directly create the portrait of the target entity through the entity information of multiple dimensions.
In a specific application, the process of creating the representation of the target entity may be: the node labels the target entity according to the first entity information and at least one second entity information, namely the entity information of multiple dimensions of the target entity, and forms a portrait of the target entity.
In addition, through the continuous increase of the number of nodes in the alliance chain, the newly added node can broadcast entity information such as personage education information of the other dimension of the target entity to other nodes, and acquire the entity information of the plurality of dimensions of the target entity which are already broadcast by the other nodes from the interface provided by the alliance chain, so that the dimension of the entity information of the target entity acquired by each node can be continuously expanded. Preferably, the images of the target entities created by the nodes in the federation chain can be updated in real time along with the updating of the target entity information in the federation chain.
In some embodiments, as shown in fig. 4, which is a schematic flow chart before step S204 in fig. 2 in the method for creating an portrait of an entity according to an embodiment of the present application, before creating a portrait of a target entity, the node further includes:
step S401, the node receives a data acquisition request sent by the user terminal.
Step S402, the node responds to the data acquisition request and sends the first entity information and at least one second entity information to the user terminal so as to instruct the user terminal to create the portrait of the target entity according to the first entity information and the at least one second entity information.
It may be understood that the user terminal outside the federation chain may access the first entity information and the at least one second entity information, that is, the entity information of the multiple dimensions of the target entity, in the federation chain through the interface provided by the application layer of the federation chain, and may also obtain the first entity information and the at least one second entity information, that is, the entity information of the multiple dimensions of the target entity, in the federation chain from the node in the federation chain by communicating with the node in the federation chain.
In some other embodiments, as shown in fig. 5, another flow chart before step S204 in fig. 2 of the method for creating an entity portrait provided in the embodiment of the present application, before creating a portrait of a target entity, the node further includes:
step S501, the node counts the data amount of the first entity information and at least one second entity information.
Step S502, the node judges whether the data amount is larger than a data amount threshold.
In step S503, if yes, the node stores the first entity information and at least one second entity information into a local entity information database.
It can be understood that, in the embodiment of the present application, before creating the representation of the target entity according to the first entity information and the at least one second entity information, it may be determined whether to store the first entity information and the at least one second entity information in the local entity information database based on the data amounts of the first entity information and the at least one second entity information, so as to achieve the effect of improving the data processing efficiency.
As can be seen from the foregoing, in the embodiment of the present application, each node broadcasts the acquired first entity information of the target entity to other nodes in the federation chain, receives at least one second entity information broadcast by the other nodes to the federation chain, and creates a representation of the target entity according to the first entity information and the at least one second entity information. On the one hand, as the information content represented by the first entity information and the second entity information are different and the information content represented by each second entity information is different, the portrait is created by using the multidimensional entity information, so that the created entity portrait is objective; on the other hand, by utilizing the characteristics of the information of the block chain, such as non-falsification, the created entity portrait is more real; in yet another aspect, the node may directly construct the entity representation such that the entity representation is created more timely.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present application.
