Specifically, the coding types of the tracking identification codes can be divided into three coding systems of industry standard coding, compatible coding and standard coding, and the uniformity of the coding can be realized by the electronic tracking identification chain for different types of tracking identification codes. For example, the unified format of the electronic tracking identification chain may be set, and may include a coding type, item information, an original tracking identification code, a standard tracking identification code, producer information, owner information, usage information, and the like. The code type indicates the code type of the tracking identification code of the target article, and if the tracking identification code is a bar code, the code type can be represented as 1001; the article information is information such as the name, the code, the unit and the number of the target article corresponding to the tracking identification code, and if the target article is one liter of nitric acid, the article information can be expressed as nitric acid/100001/liter/1; the original tracking identifier is the tracking identifier on the target article, fig. 2 is a schematic diagram of the original tracking identifier, and the original tracking identifier may be denoted by 1000120100001; the standard tracking identification code is a standard code which is generated by the original tracking identification code according to a unified coding rule, and can be used as a standard according to the code and an additional function code of the national standard 'important product traceability code specification'; the producer information is information of a target article producer, and mainly comprises information such as a producer name, a producer code, a producer area code, a production date, a production position and the like; the owner information is information of an enterprise or a person with ownership of the target object, and mainly comprises information such as an owner name, an owner code, an identification of whether the target object is received, a warehouse-in date, a warehouse-in position and the like; the usage information is information such as current status information and usage amount of the target article, and the status information may be status information such as production, sales, in-use, use-up and destruction, and if the target article is in a production state, the status information may be denoted by 0. By setting a unified format for the electronic tracking identification chain, the compatibility of tracking identification codes with different coding types is realized, and the tracking processing of articles is facilitated.
In this embodiment, optionally, the electronic tracking identification chain is generated when the tracking identification code on the target item is first acquired.
Specifically, after the tracking identification code of the target object is obtained, an electronic tracking identification chain is formed according to the information in the tracking identification code, and the tracking and processing conditions of the target object are obtained through the electronic tracking identification chain. When the tracking identification code of the target object is acquired for the first time, an electronic tracking identification chain can be generated, the electronic tracking identification chain is associated with the tracking identification codes, and each tracking identification code corresponds to one electronic tracking identification chain. In the first generated electronic tracking identification chain, the producer information is consistent with the owner information, which may be modified during the delivery of the target item. The electronic tracking identification chain stores the transfer record data of the target object, and when the tracking identification code is acquired each time, the latest transfer record data is displayed in the electronic tracking identification chain, and the transfer condition of the target object can be checked according to the electronic tracking identification chain.

The electronic tracking identification chain is checked, latest delivery record data of the target object are obtained, and the latest state of the target object is determined according to the latest delivery record data, so that tracking processing is conducted on the target object according to the latest state. For example, based on the latest transfer record data, the current owner of the target item can be determined, and tracking of the target item is achieved based on the current owner. And comparing the latest state of the target object displayed by the latest transmission record data in the electronic tracking identification chain with the actual state, so that the authenticity of the target object can be distinguished.

Specifically, the actual owner of the target object is the owner of the current real owned target object, and the actual owner information may not be consistent with the current owner information in the electronic tracking identification chain. The staff inputs the actual owner information of the target object into the application program, and the application program system acquires the actual owner information. And identifying the tracking identification code of the target object, and acquiring the latest transmission record data in the electronic tracking identification chain. And determining the current owner information of the target object according to the latest transmission record data of the target object in the electronic tracking identification chain. Comparing the actual owner information with the current owner information, and if the actual owner information of the target object is consistent with the current owner information, determining that the target object is true; if not, the target object is abnormal. For example, the actual owner of the target item is B, and the latest transfer record data indicates that the current owner of the target item is a, that is, there is a case that B replaces the tracking identification code of the target item on another item, and the item is false although the tracking identification code is attached to the item; and B, the situation that the target object is stolen and changed in the transfer process exists, and the transfer process of the target object is proved to be abnormal. The electronic tracking identification chain has the beneficial effects that tracking of the target object can be rapidly realized by acquiring the latest transmission record data of the target object in the electronic tracking identification chain, authenticity and abnormality of the target object are determined according to the actual condition of the target object, and the tracking processing efficiency of the target object is improved.

In particular, the owner information in the electronic tracking identification chain may be modified by the current owner during delivery of the target item. Determining a current owner of the target object according to an electronic tracking identification chain of the target object, logging in the application program by a user, identifying the identity of the user by an application program system, and if the identity of the user is consistent with the identity of the current owner, determining that the user is the current owner and giving the user modification permission of the information of the current owner. And modifying the owner information in the latest delivery record into the information of the next owner by adopting the modification authority by the current owner, and updating and storing the latest delivery record data. For example, confirming that the current owner of the target item is a, which passes the target item to C, a may modify the current owner information to that of C. After the updated latest transfer record data is written in the electronic tracking identification chain, the tracking identification code is identified, so that the updated latest transfer record data in the current transfer stage can be displayed, the latest transfer record data does not need to be searched from the historical transfer record data, and the tracking time is effectively saved.
According to the technical scheme of the embodiment, the electronic tracking identification chain containing the target article information is obtained by acquiring the tracking identification code on the target article, and tracking processing of the target article is realized according to the electronic tracking identification chain. The problem that target data are searched from a large number of tracking tracing data in the prior art and the problem that different systems are required to be identified by different types of tracking identification codes are solved, the purpose that any tracking identification code can be tracked through an electronic tracking identification chain is achieved, and the article tracking efficiency is improved.
Example two
Fig. 3 is a flow chart of a tracking method based on an electronic tracking identification chain according to a second embodiment of the present invention, which is further optimized based on the above embodiment, and the method may be performed by a tracking device based on the electronic tracking identification chain. As shown in fig. 3, the method specifically includes the following steps:
Step 310, obtaining the tracking identification code on the target article.
Step 320, using the electronic tracking identification chain associated with the tracking identification code as the electronic tracking identification chain of the target object; the electronic tracking identification chain stores transfer record data of the target object, and the transfer record data comprises a first ciphertext of the transfer record.
The first ciphertext of the transfer record is obtained by encrypting the original text of the transfer record and the second ciphertext of the transfer record by adopting a key of a next owner, the next owner information is determined after the current owner obtains the modification authority and updates the latest transfer record data, and the current owner information in the updated latest transfer record data is the next owner information. After determining the information of the next owner, the system configures a key for the next owner, obtains a first key for transmitting and recording according to the key of the next owner, and can encrypt in an asymmetric encryption mode. The transfer record original text is related data of a public target object which can be checked by a person in the electronic tracking identification chain, the transfer record original text can comprise information such as a transfer state, a warehouse-in and warehouse-out time, a warehouse-in and warehouse-out position and the like of the target object, the transfer record second ciphertext is obtained by encrypting the transfer record original text by adopting a fixed key of the system, and the data leakage in the second ciphertext can be avoided by adopting the fixed key of the system.
Step 330, decrypting the first ciphertext of the transfer record by adopting the key of the next owner to obtain the original text of the transfer record; and tracking the target object according to the transfer record original text.
When the target object is tracked, a first ciphertext of the transfer record in the transfer record data is obtained, and the first ciphertext of the transfer record is decrypted by adopting a key of the next owner, so that a transfer record original is obtained. Determining the latest transfer record data according to the transfer record text, acquiring current owner information from the latest transfer record data, and determining that the target object is true if the actual owner information of the target object is consistent with the current owner information; if not, the target object is abnormal.
In this embodiment, optionally, the transfer record data further includes a transfer record text.
Specifically, the transfer record data may include a transfer record original text and a transfer record first ciphertext, and the transfer record first ciphertext may include a transfer record original text and a transfer record second ciphertext. The transfer record original text in the transfer record first ciphertext and the transfer record second ciphertext cannot be leaked or randomly changed due to being encrypted by the next owner key, but the transfer record original text in the transfer record data can be maliciously changed.
Tracking the target object according to the electronic tracking identification chain of the target object, and further comprising: decrypting the first ciphertext of the transfer record by adopting the key of the next owner to obtain a second ciphertext of the transfer record; encrypting the transmission record original text in the transmission record data by adopting a fixed key to obtain a transmission record third ciphertext; and comparing the second ciphertext of the transfer record with the third ciphertext of the transfer record, and if the second ciphertext of the transfer record is consistent with the third ciphertext of the transfer record, not falsifying the transfer record data.
Specifically, whether the transmission record data is tampered can be checked, after the transmission record text in the transmission record data is obtained, the transmission record text can be encrypted by adopting a fixed key, and the encrypted transmission record third ciphertext is obtained. And decrypting the first ciphertext of the transfer record by adopting the key of the next owner to obtain a second ciphertext of the transfer record, wherein the second ciphertext of the transfer record is also obtained by encrypting the original text of the transfer record by adopting the fixed key. The second ciphertext of the transfer record and the third ciphertext of the transfer record can be expressed by hash values, the second ciphertext of the transfer record and the third ciphertext of the transfer record are compared, and if the second ciphertext of the transfer record and the third ciphertext of the transfer record are consistent, the transfer record data is proved not to be tampered; if not, the transfer record data is proved to be tampered. For example, the transfer record data includes a transfer record original text and a transfer record first ciphertext, the transfer record original text is an owner name a and an owner code 1, the transfer record first ciphertext includes a transfer record original text and a transfer record second ciphertext, and the transfer record second ciphertext encrypts the owner name a and the owner code B, and is denoted by 001. If someone maliciously tampers with the owner information, only the transfer record original text in the transfer record data can be tampered, the name of the owner is changed to B, and the code of the owner is changed to 2. The application program system encrypts the modified transmission record original text by adopting a secret key consistent with the second ciphertext of the transmission record, and the encrypted third ciphertext of the transmission record is changed into 002 because the transmission record original text is changed, and the 001 is compared with the 002 to know that the transmission record original text in the transmission record data is tampered. The supervision and management of the transmission record data are effectively realized, and the accuracy of tracking and processing the target object is improved. Each time after the current owner modifies the owner information to the owner information of the next owner, the system may configure a different private key to encrypt the transferred record data to obtain verification encrypted information, where the verification encrypted information may include a hash value of the transferred record data and the owner information of the target object in the electronic tracking identification chain. By decrypting with the public key, the hash value of the electronic tracking identification chain data and the owner information of the target article are read, and whether the data in the electronic tracking identification chain is changed and whether the article owner is correct is verified through the hash value.
According to the embodiment of the invention, the electronic tracking identification chain containing the target article information is obtained by acquiring the tracking identification code on the target article, and the tracking processing of the target article is realized according to the electronic tracking identification chain. By encrypting the transmission record data, the authenticity of the transmission record data is improved, the problem that in the prior art, target data is searched from a large amount of tracking tracing data and the problem that different systems are required to be identified by different types of tracking identification codes are solved, and the tracking processing of any tracking identification code through an electronic tracking identification chain is realized. By encrypting the transmission record data, the authenticity of the transmission record data is improved, the transmission record data is prevented from being tampered maliciously, and the tracking efficiency of the article is improved.
