The existing industrial internet identification analysis system comprises a Handle identification analysis system, an OID identification analysis system, a national internet of things Ecode identification analysis system, a global commodity identification GS1 identification analysis system and the like. The Handle identification analysis system generally uses an external database storage mode. After receiving a query request of a client, the Handle identification analysis system needs to search results in an external database, then copies the searched results into a program memory, assembles the results into a response message and returns the response message to the client. The OID identification analysis system can provide storage and analysis services based on OID codes for the identification based on the identification OID service platform, the application workstation reads the OID number of the identification by using the RFID reader-writer and transmits the OID number to the OID service platform, and the OID service platform returns analysis information of the OID number according to the read OID number.

In an example, an identifier parsing request of a user may be directly received, or an identifier parsing request of the user may be obtained from another server, where the block chain server stores parsing information of an identifier in the parsing request, the parsing information may be directly sent out, and where the block chain server does not store the parsing information of the identifier in the parsing request, an address, such as an IP address, of a server where the parsing information matching the identifier is located is queried through an identifier address index.
In the embodiment of the disclosure, the resolution information of the identifier is stored in a plurality of blockchain servers, the blockchain servers can directly resolve the resolution request of the identifier, and under the condition that the resolution information of the identifier cannot be determined, the server address where the resolution information of the identifier is located is determined from the identifier address index, so that network congestion is reduced, the query efficiency of a user is improved, the identifier address index is shared among all blockchain nodes, and under the condition that one blockchain node has a problem, other blockchain nodes still store the identifier address index, so that the security of data storage is improved.
In one possible implementation, the blockchain node further comprises a local server,

In the embodiment of the present disclosure, the local server may include various user terminals, such as a mobile phone, a notebook, a tablet computer, a personal computer, and the like. In one example, the local server may also have a scanning function, such as a camera and corresponding application, to identify the identity. In one example, the local server may also have a display function to present the identified parsed information. After receiving an identifier analysis request sent by a user, the local server sends the analysis request to the block chain server, and receives the identifier analysis information or the server address where the identifier analysis information is located, which is returned by the block chain server. In one example, if the blockchain server returns the identified resolution information, the local server directly returns the identified resolution information to the user.

And returning the analysis information to the user. The target server may comprise the above-described blockchain server. In an embodiment of the present disclosure, the target server includes a blockchain server at a different blockchain node from the local server. For example, referring to fig. 2, the local server 107 receives an analysis request of an identifier sent by a user, and sends the analysis request to the blockchain server a (2) 104, and receives the analysis information of the identifier returned by the blockchain server a (2) 104 or a server address where the analysis information of the identifier is located, and after receiving the server address where the analysis information of the identifier is located, for example, the server address is an address of the blockchain server B, the local server 107 sends the analysis request of the identifier to the blockchain server B, and receives the identification analysis information returned by the blockchain server B.
In one possible implementation, the local server includes a caching module that stores the identified historical resolution information,
the local server is further configured to determine, after receiving an analysis request of the identifier sent by the user, analysis information of the identifier from the cache module, and send the analysis request to the block chain server if the analysis information of the identifier is not cached.
In the embodiment of the present disclosure, the cache module caches an analysis record for performing identifier analysis by the local server. After receiving the resolution request of the identifier sent by the user, firstly determining the resolution information of the identifier from the cache module, if the historical resolution information of the identifier is cached in the cache module, the resolution information of the identifier can be rapidly determined, the block chain server does not need to be accessed, and the access pressure to the block chain server is reduced.
In a possible implementation manner, the local server is further configured to record the resolution information of the identifier to the cache module after receiving the resolution information of the identifier returned by the blockchain server, and periodically delete the resolution information of which the recording time is greater than a preset value, so as to update the cache module.
In the embodiment of the disclosure, in order to prevent the original resolution record from being still stored in the local server after the resolution information is updated, and thus when a new resolution request is generated, the non-updated resolution information is returned to cause an error resolution, a regular updating mode is adopted for the resolution record in the cache module, and the resolution information with the recording time longer than the preset value is deleted. As in the previous embodiment, the resolution record cached in the local server is derived from a historical resolution record that was resolved by the local server.
In a possible implementation manner, the local server includes a configuration module, where the configuration module includes an association relationship between an identifier category and a blockchain server, and the local server is further configured to, after receiving an analysis request of an identifier sent by a user, identify, by using the configuration module, the category identified in the analysis request, determine a blockchain server matched with the category, and send the analysis request to the blockchain server.
In the embodiment of the present disclosure, the identifier category may include a Handle identifier, an OID identifier, an Ecode identifier, and a GS1 identifier. In one example, the identification category may be obtained from a local input, a blockchain server, or a registration resolution server of a public identification system, and may also obtain other network connection information, and the like. And the local server is also used for identifying the type of the identifier in the analysis request by using the configuration module after receiving the analysis request of the identifier sent by the user, and determining the block chain server matched with the type. In one example, for example: the local server identifies the identification type in the analysis request, if the analysis request only contains digital texts and is separated by taking ". multidot.X" as a separator layer, the identification type of the analysis request can be judged to be an OID (object identifier), and the analysis request is sent to a block chain server matched with the OID; in another example, if a hierarchical structure with "/" as a separator exists in the parsing request, and the "/" is preceded by numerical information with ". -" as a separator, and the "/" is followed by a character or a numerical combination, it may be determined that the identifier type is a Handle identifier, and the parsing request is sent to a blockchain server matched with the Handle identifier; in another example, if "E =" is used as an initiator in the parsing request, multi-node fixed writing is adopted, or an RFID segmented storage format is used to store an "E = V + NSI + MD" tag, it may be determined that the identification category is an Ecode identification, and the parsing request is sent to a blockchain server matching the Ecode identification; in another example, if the GTIN-8/12/13/14 encoding structure, or the 18-bit digital coding SSCC structure, or the 13-bit digital coding GLN structure is satisfied in the parsing request, it may be determined as the GS1 identifier, and the parsing request is sent to the blockchain server matching the GS1 identifier; in another example, after receiving a resolution request of an identifier sent by a user, the local server returns a resolution failure message to the user if the configuration module does not recognize the category identified in the resolution request. It should be noted that the setting manner of the identification category is not limited to the above examples, and those skilled in the art may make other modifications within the spirit of the present application, and all that is required is to cover the protection scope of the present application as long as the achieved function and effect are the same or similar to the present application.

The local server also can carry out cleaning and re-duplication operations on the acquired marking category data, and dynamically stores the acquired marking categories into a local log, and the local server is also used for synchronizing the processed marking categories into a block chain server.
The configuration module of the local server in the embodiment of the disclosure comprises a plurality of identification categories, can identify different identification categories in the analysis request, and analyzes the identification analysis requests of different identification categories, thereby improving the applicability of the system.
In one possible implementation, the blockchain server matching the category includes a blockchain server at the same blockchain node as the local server and a blockchain server at a different blockchain node from the local server.
In the embodiment of the present disclosure, the blockchain nodes may be divided according to geographic areas, for example, a blockchain server and a local server in beijing area are located at the blockchain node a, a blockchain server and a local server in tianjin area are located at the blockchain node B, and a blockchain server and a local server in nanjing area are located at the blockchain node C.
In the embodiment of the present disclosure, after the local server identifies the identifier type, the local server may match the blockchain server from the server located in the same blockchain node as the local server, and if the server of the blockchain node is not located, the local server may find the identifier type from the blockchain server located in a different blockchain node from the local server. In one example, for example, a local server of a block link point a obtains an identifier resolution request, reads an identifier category, and sends the identifier resolution request to a blockchain server if there is a blockchain server matching the identifier category in the block link point a; if there is no blockchain server in blockchain node a that matches the identification category, then blockchain servers in other blockchain nodes are matched.
In a possible implementation manner, the blockchain server includes a storage module, the storage module is configured to receive and store an identifier and corresponding identifier resolution information, and the blockchain server periodically updates its address and the identifier stored in the storage module to the identifier address index.
In the embodiment of the present disclosure, the storage module may receive an identifier and resolution information of the identifier sent by a local server or another blockchain server, and the blockchain server periodically updates its address and the identifier stored in the storage module to the identifier address index.
