Description
Technical Field
The invention belongs to the technical field of Internet of things identification analysis, and particularly relates to a distributed object identification information registration and analysis method.
Background
The perception and control of the physical world are introduced into the Internet of things, so that the communication cooperation between objects and between people becomes possible. The object identification and analysis are the premise and the basis of the communication of the Internet of things. Identification refers primarily to a digital code that gives an object a unique identity. So that the application can control and manage the target object. The analysis mainly refers to a process of mapping a certain Internet of things identifier to other Internet of things identifiers or information related to the certain Internet of things identifier, and mainly solves the problem of mapping and converting the identifier.
Currently, a centralized or tree-shaped distributed network structure is mostly adopted in the field of analysis. The functions of each node in the tree-shaped distributed network structure are different, such as a local node, a root node, a top node and the like in the DNS, and different nodes provide different functions. When the parsing function is used, the final service node is selected according to the route. The centralized network structure provides services to the outside mainly through a central server.
In the current technical scheme for analyzing the identification of the internet of things, a tree or centralized network structure depends on a single service node, and the main defects are as follows: the parsing of the object must be server based, and once a single point server is attacked or deliberately altered, the parsing service will be in error. Furthermore, as the number of accessed objects or devices increases dramatically, the load of the single-point server increases, and thus the maintenance cost for the server also increases dramatically.
Disclosure of Invention
In view of this, the present invention provides a method for registering and analyzing distributed object identifier information, which can solve the problem of relying on a single-point server in registering and analyzing object identifiers in the internet of things through a blockchain technology, wherein nodes in the blockchain technology are mutually equivalent, each node can provide service to the outside in an equivalent manner, and even if a bad node occurs, the whole service is not affected.
The technical scheme for realizing the invention is as follows:
a method for registering and analyzing distributed object identification information comprises the following steps:
step one, building a block chain network;
step two, establishing a transaction by using a node of the block chain network, wherein the establishing transaction is as follows: organizing the identification information in a set transaction format;
step three, broadcasting the created transaction to other nodes in the blockchain network; after receiving the created transaction, other nodes verify the transaction format, if the transaction format passes the verification, the other nodes continue broadcasting until the created transaction is transmitted to the whole block chain network, otherwise, the other nodes do not broadcast;
selecting any node of the block chain network to create a block under a DPOS authorized share certification mechanism;
step five, broadcasting the created block to other nodes in the block chain network; the node receiving the block verifies the block structure, after the verification is passed, the node is accessed into the block and continuously broadcasts to other nodes until all the nodes are accessed into the block, namely the registration of the object identification information is completed;
and step six, sending an analysis request to a node in the block chain network through the block chain client, and acquiring an analysis result corresponding to the object identification information.
Further, the specific process of constructing the blockchain network is as follows:
selecting a plurality of main nodes which are stably operated network nodes, randomly selecting one main node for connection by a newly accessed node, acquiring a node list connected to the main node, and randomly selecting the node from the acquired list for connection.
Further, the specific process of constructing the blockchain network is as follows:
a new node designates a node for connection when accessing; acquiring a list connected to a designated node through the designated node; and randomly selecting nodes from the acquired list for connection.
Further, the set transaction format is a json data structure.
Has the advantages that:
1. the invention aims at the problem that the current identification analysis technology is greatly influenced by a single-point server, and the block chain technology is utilized, so that the analysis service is innovated in a deployment mode, the dependence on the single-point server is eliminated, all nodes of the block chain are mutually equivalent, and the data can not be falsified, therefore, the analysis node can be deployed in the same local area network with the application, and can be completed in the local area network when the analysis request is carried out, the request is not required to be carried out through the Internet, and the analysis service has the effect of avoiding the influence of Internet factors.
2. The invention sets the json data structure transaction format which is easy to expand when in implementation, so that the system has stronger expansibility on a service level.

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
The implementation scheme of the invention mainly comprises three parts, namely how to construct the block chain network and how to broadcast data in the network, how to register object identification information in the block chain network and how to analyze the identification information in the block chain network. As shown in fig. 1, the method specifically comprises the following steps:
step one, building a block chain network;
the method for constructing the blockchain network mainly solves the problem of how to add a new node into the network, and two ways are provided, first, it is explained that some main nodes are stably operated by the system, and fig. 2 is an access way one: the construction process of the first mode comprises the following steps:
selecting a plurality of main nodes which are stably operated network nodes, randomly selecting one main node for connection by a newly accessed node, acquiring a node list connected to the main node, and randomly selecting the node from the acquired list for connection.
Fig. 3 is a construction mode 2:
a new node designates a node for connection when accessing; acquiring a list connected to a designated node through the designated node; and randomly selecting nodes from the acquired list for connection.
Step two, establishing a transaction by using a node of the block chain network, wherein the establishing transaction is as follows: organizing the identification information in a set transaction format; the set transaction format is a json data structure for storing information, and is used for bearing specific identification information or other data.
The object identification information needs to be written into the block chain, which also includes an update operation on the identification information. In the process, firstly, a transaction format (namely a data format) is created to carry different data and describe different operation types, the transaction creation is the first step of data writing, the related nodes need to format the identification information in the transaction format, and the identification information can be written into the block chain by means of transaction when the transaction format exists.
Step three, broadcasting the created transaction to other nodes in the blockchain network; after receiving the created transaction, other nodes verify the transaction format;
after the transaction is established, data needs to be transmitted to other nodes in a data broadcasting mode, after the other nodes receive the data, data verification is carried out according to certain standards to judge whether the data meet requirements, if the data meet the requirements, the data are continuously broadcasted until the data are transmitted to the whole network, otherwise, the data are not broadcasted.
Selecting any node of the block chain network to create a block under a DPOS authorized share certification mechanism;
the block is an organization form of transaction, and one block comprises a plurality of transaction messages. Firstly, the related nodes are selected according to a consensus mechanism for generating the blocks, and the invention adopts a DPOS (authorized share certification mechanism) consensus mechanism.
Step five, broadcasting the created block to other nodes in the block chain network; the node receiving the block verifies the block structure, after the verification is passed, the node is accessed into the block and continuously broadcasts to other nodes until all the nodes are accessed into the block, namely the registration of the object identification information is completed;
after the node generates the block, the node broadcasts the block to other nodes, and after the other nodes receive the block, the other nodes verify the block according to a certain standard. And after the node passes the verification of the received block, the node is accessed into the block chain network and continues to forward, and finally the object identification information is written into the block chain.
And step six, sending an analysis request to a node in the block chain network through the block chain client, and acquiring an analysis result corresponding to the object identification information.
Fig. 4 illustrates a deployment diagram of an application during identity resolution, because each node of the blockchain provides services peer to peer, when the blockchain node is redeployed, the blockchain node can be deployed in the same local area network as the application. Therefore, when the application carries out the analysis request, the analysis service node in the local area network is requested preferentially. After a certain node of the external block chain fails, the whole analysis service cannot be influenced, and the single-point server is free from constraint.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
