S302, the tracing device 100 determines first information according to the article identifier of the article to be traced.
The first information is article information corresponding to an article identifier of an article to be traced stored in a server (article information server 300).
Illustratively, the tracing apparatus 100 sends the received industrial internet identification of the article to be traced and an article information query request to the article information server 300. The article information server 300, after receiving the industrial internet identification of the article to be traced and the article information query request, queries the article information corresponding to the industrial internet identification of the article to be traced through the industrial internet identification, and then sends the article information corresponding to the industrial internet identification of the article to be traced to the tracing device 100 after querying the article information corresponding to the industrial internet identification of the article to be traced. Correspondingly, the tracing device 100 receives the article information corresponding to the industrial internet identifier of the article to be traced sent by the article information server 300.
It is worth mentioning that the article information may include status information of the article, location information of the article, and other information of the article (e.g., a manufacturer name of the article, a name of a person in charge of the article, a sales area of the article, a material of the article, a packaging manner of the article, etc.).
And S303, the tracing device 100 determines second information according to the article identifier of the article to be traced.
The second information is item information corresponding to the item identifier stored in the block chain 500.
Illustratively, the tracing apparatus 100 sends the received industrial internet identification of the article to be traced and an article information query request to the blockchain 500. After receiving the industrial internet identification of the article to be traced and the article information query request, the block chain 500 queries the article information corresponding to the industrial internet identification of the article to be traced through the industrial internet identification, and then sends the article information corresponding to the industrial internet identification of the article to be traced to the tracing device 100 after querying the article information corresponding to the industrial internet identification of the article to be traced. Correspondingly, the tracing device 100 receives the article information corresponding to the industrial internet identifier of the article to be traced sent by the block chain 500.
In a possible implementation manner, the tracing apparatus 100 may determine, according to the article identifier of the article to be traced, the encrypted information corresponding to the article identifier of the article to be traced, and then decrypt the encrypted information corresponding to the article identifier of the article to be traced to obtain the second information. Wherein the encrypted information includes second information.
Illustratively, the tracing apparatus 100 sends the received industrial internet identification of the article to be traced and an article information query request to the blockchain 500. After receiving the industrial internet identification of the article to be traced and the article information query request, the block chain 500 queries the encrypted information corresponding to the industrial internet identification of the article to be traced through the industrial internet identification of the article to be traced, and then sends the encrypted information corresponding to the industrial internet identification of the article to be traced to the tracing device 100 after querying the encrypted information corresponding to the industrial internet identification of the article to be traced. Correspondingly, the tracing device 100 receives the encrypted information corresponding to the industrial internet identifier of the article to be traced sent by the block chain 500, and then decrypts the encrypted information corresponding to the industrial internet identifier by using a decryption algorithm matched with the encrypted information to obtain the article information corresponding to the article identifier stored in the block chain 500.

In a possible implementation manner, the tracing apparatus 100 may first generate a hash value of the first information through a hash algorithm, then generate a hash value of the second information through the hash algorithm, compare the hash value of the first information with the hash value of the second information, and send the first information to the user equipment 700 under the condition that the hash value of the first information is the same as the hash value of the second information.
In another possible implementation manner, the tracing apparatus 100 may determine whether the first information is tampered with through an algorithm relationship according to the acquired encryption information and the first information. The first information is then sent to the user device 700 in case the first information has not been tampered with.
In another possible implementation manner, the encrypted information acquired by the trace back device 100 is a hash value of the second information, in this case, the trace back device 100 may first generate a hash value of the first information through a hash algorithm, then compare the hash value of the first information with the hash value of the second information, and send the first information to the user equipment 700 when the hash value of the first information is the same as the hash value of the second information.
Accordingly, the user equipment 700 receives the first information. The user may view status information of the item, location information of the item, and other information of the item (e.g., a manufacturer name of the item, a name of a person in charge of the item, a sales area of the item, a material of the item, a packaging manner of the item, etc.) through the first information received by the user device 700.
Through S301 to S304, it can be seen that, after receiving a trace back request sent by a user equipment, according to an article identifier of an article to be traced in the trace back request, the embodiment of the present invention obtains article information corresponding to the article identifier of the article to be traced from a server and a block chain, respectively, and then sends the article information of the article to be traced in the server to the user equipment only when the article information obtained in the two ways is consistent. Due to the fact that the block chain has the characteristic of being not capable of being tampered, the article information of the article to be traced in the block chain is not tampered.
