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 only a part of the embodiments of the present application, and not all of the embodiments. 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.

The industrial internet identification analysis method provided by the embodiment of the application is applied to, but not limited to, scenes of mutual access between different types of identification analysis systems through interaction between a client and a node of a block chain.

Fig. 1 is an architecture of an identifier resolution system according to an embodiment of the present application, and includes a client (including a proxy node in fig. 1) and a node forming a block chain (referred to as a node of the block chain for short), where the node on the block chain includes a consensus node, and the consensus node has functions including: and participating in consensus and having accounting right, issuing a new block, and completing identification registration and resolution. The client is downloaded by a user and runs on the equipment, and then performs information interaction with the common identification node, so that mutual access among different types of identification analysis systems is realized.

The consensus node interacting with the client may be predetermined according to the type of the user (i.e., the user bound to the client), or selected by the client. Specifically, the selection may be performed according to a proximity principle, and optionally, the proximity principle includes, but is not limited to: the logical address is closest, or the physical distance is closest.

Specifically, the predetermined process according to the type of the user (i.e. the user bound to the client) is: when the client runs for the first time, according to the type of a user of the client (such as prompting the user to select the type as an individual user, a centralized registration mechanism (mechanism) or an decentralized registration mechanism (mechanism) (for example, based on a blockchain registration mechanism)), a proxy node corresponding to the type of the user is generated on the device, and a public and private key pair is generated and stored in the device. When the type of the user is the centralized registry, the corresponding consensus node is called a cross-domain node. When the type of the user is based on the block chain registry, the corresponding consensus node is called a cross-link node. Similarly, after the client selects the consensus node, if the user type is the centralized registration authority, the consensus node selected by the client is called a cross-domain node. In the case that the type of the user is based on the block chain registration mechanism, the consensus node selected by the client is called a cross-chain node.

The cross-domain nodes communicate with agent nodes of the centralized registration authority, and the functions of the cross-domain nodes comprise: and participating in consensus and possessing the accounting right, providing cross-domain management service, interfacing with the existing or newly-built centralized registration mechanism (comprising GS1, handle, OID and the like), and linking the information, the coding prefix, the service address and the public key of the proxy node.

The cross-link node communicates with a proxy node of a blockchain registry, and the functions of the cross-link node include: the method participates in consensus and has accounting right, and simultaneously provides cross-chain management service, namely participates in consensus of a native chain and also participates in consensus of other blockchains (such as the blockchain where the agent node of the blockchain registration mechanism is located), and simultaneously, the other blockchains register chain identification to a main chain (namely the blockchain interacting with each agent node), and the main chain checks uniqueness of the chain identification. In the case where there are cross-link points in a node of a blockchain, the blockchain may serve as a main chain, and the distributed identity registration mechanism based on the blockchain is referred to as a child chain.

The consensus node communicates with the agent nodes of the individual users.

The specific process for implementing mutual access between different types of identifier resolution systems will be described in detail below based on different types of users of the client.

In this embodiment, the type selected by the user is the centralized registration mechanism, and the system bound by the client (i.e., the first identifier resolution system) is the centralized identifier resolution system. It should be noted that the client binds the system when running for the first time, and saves the bound system in the device, and the binding does not need to be rebound when running for the next time.

S202, the client establishes a proxy node in the first identifier analysis system and generates a public and private key pair.

In this embodiment, the proxy node in the centralized identifier parsing system is an operator of the centralized registration authority, and is responsible for formulation of the identifier coding rule and allocation and registration of the identifier.

			Recording attributes	4 bytes	Central proxy node (central register organization)
Identification prefix	4 bytes	First identification resolution system self-defining (reserved public identification prefix)
			Type of operation	4 bytes	Register/update/delete, etc
Modifying content	256 bytes	Proxy node information, IP address
			Remark information	128 bytes	Additional content

			Time stamp	4 bytes	Recording the time of issue

It should be noted that, in table 1, the value of the record attribute field is the central proxy node, and indicates that the information is sent by the proxy node established in the centralized identity resolution system.

In this embodiment, after the cross-domain node obtains the verification result of the information, the information for registration sent by the proxy node is stored.

It should be noted that, after the cross-domain node stores the information for registration sent by the proxy node, the registration is successful, and at this time, each consensus node on the blockchain may store the information. Further, the cross-domain node feeds back a registration success message to the proxy node.

1. the method allocates an identification prefix in advance for a known standard mechanism, the identification prefix is used as a reserved public identification prefix and cannot be used by other identification analysis systems any more, namely the identification prefix only indicates one identification analysis system, and an object of the identification prefix indicating the analysis information of the storage identification can comprise a centralized identification analysis system, an identification analysis system based on a block chain or an individual user, so that even if the system bound by a client does not have an identification to be inquired, the analysis information can be obtained through the identification prefix, and the mutual access of different analysis systems taking a node in the block chain as a bridge is realized.

2. Based on the characteristics of the block chain, the safety under the condition of mutual access is ensured.

3. Based on an intelligent contract mechanism of the block chain, data is stored in a plurality of nodes participating in consensus in the block chain, and the problem that continuous service cannot be provided due to the fact that a single analysis block chain link point fails is solved.

4. Based on the characteristic that data in the blockchain has non-falsification, the safety of data access is further improved.

As described above, the client may pre-bind the first identifier resolution system, specifically, the centralized identifier resolution system or the identifier resolution system based on the block chain, and optionally, the client may also pre-bind the individual user.

The case where the object is not the first identity resolution system is: the object is an identification analysis system based on a block chain or other centralized identification analysis systems, or the object is a consensus node.

The target node is a consensus node corresponding to the type of the system to which the client is pre-bound, and specifically, as described above, the system to which the client is pre-bound is a centralized identifier analysis system, the target node is a cross-domain node, the system to which the client is pre-bound is an identifier analysis system based on a block chain, and the target node is a cross-chain node.

Because the identifier prefix indicates an object for storing the analysis information, even if different identifier analysis systems are incompatible or an identifier to be queried does not exist in a system bound by the client, the analysis information can be acquired through the identifier prefix, so that mutual access of the different analysis systems by taking a node in the block chain as a bridge is realized. Furthermore, the method ensures the safety under the condition of mutual access based on the characteristic of a consensus mechanism of the block chains.
