Taking the merchant management server 20a as an example, after receiving the agricultural product transaction related information, the merchant management server 20a generates agricultural product information to be traced and files the agricultural product information to be traced into an agricultural product sales knowledge map; at TimeA, the merchant management server 20a sends an agricultural product archiving instruction to the central server 10, the agricultural product archiving instruction includes the first agricultural product status data, the first agricultural product state data is agricultural product state data of agricultural product information to be traced at the TimeA time point, the agricultural product status data may include a supplier identifier of agricultural product information to be traced, a sales information identifier at TimeA time point, and a digest ciphertext of the sales information identifier at TimeA time point, after the central server 10 acquires the first agricultural product status data, the agricultural product information node may be generated by using the first agricultural product state data as a part of the agricultural product transaction-related information (i.e. the first agricultural product state data belongs to data in node information in the agricultural product information node), filing the agricultural product information nodes into an agricultural product center management knowledge graph corresponding to the central server 10; thereafter, the merchant management server 20a sends an agricultural product traceability instruction to the central server 10 at the TimeB time point, the agricultural product traceability instruction includes second agricultural product state data, the second agricultural product state data may include a supplier identifier of the agricultural product information to be traceable at the TimeB time point, a sales information identifier at the TimeB time point, and a sales information identifier summary ciphertext at the TimeB time point, after the central server 10 acquires the second agricultural product state data, the agricultural product information node is acquired from the agricultural product central management knowledge map according to the supplier identifier, then the first agricultural product state data in the node information of the agricultural product information node is acquired, a result of traceability operation is determined by comparing the first agricultural product state data and the second agricultural product state data, that is, whether the agricultural product information to be traceable at the TimeA time point is equal to the agricultural product information to be traceable at the TimeB time point is determined, and then verifying whether the agricultural product information to be traced is subjected to industrial chain change after filing. As can be seen from the above, the merchant management server 20a stores the specific agricultural product transaction related information sent by the offline commodity sales server 30, the central server 10 stores the agricultural product state data (including the supplier identifier, the sales information identifier corresponding to the supplier identifier, and the sales information identifier summary ciphertext corresponding to the supplier identifier) in the agricultural product sales knowledge graph, the storage pressure of the central server 10 and the agricultural product central management knowledge graph is relieved, and the traceability reliability of the agricultural product transaction related information in the agricultural product sales knowledge graph is also ensured through subsequent verification. In addition, the information related to the agricultural product transaction stored in the offline commodity sales server 30 may be exchanged, that is, the information related to the agricultural product transaction in the offline commodity sales server 30a may be transmitted to the offline commodity sales server 30b or the offline commodity sales server 30c, and similarly, the information related to the agricultural product transaction in the offline commodity sales server 30b may be transmitted to the offline commodity sales server 30a or the offline commodity sales server 30 c. The information related to the agricultural product transaction in the offline merchandise sales server 30a may be sent to the merchant management server 20a, or may be sent to the merchant management server 20b or the merchant management server 20 c; the information related to the agricultural product transaction in the offline merchandise sales server 30b may be sent to the merchant management server 20a, or may be sent to the merchant management server 20b or the merchant management server 20 c; similarly, the information related to the agricultural product transaction in the offline merchandise sales server 30c may be sent to the merchant management server 20a, or may be sent to the merchant management server 20b or the merchant management server 20 c; when the agricultural product transaction related information in the off-line commodity sales server 30a is sent to the merchant management server 20a, the merchant management server 20a firstly verifies the agricultural product transaction related information, stores the agricultural product transaction related information into the memory pool after the verification is completed, and updates the Tree used for recording the agricultural product transaction related information; then, updating the updating time stamp to the time of receiving the agricultural product transaction related information, calculating a characteristic value of the agricultural product transaction related information by using an MD5 algorithm or other cryptographic algorithms, storing the agricultural product transaction related information and a corresponding information summary ciphertext after obtaining the characteristic value (namely the information summary ciphertext), generating a sales information identifier and an agricultural product information main body, and obtaining newly generated to-be-traced agricultural product information; subsequently, the merchant management server 20a sends the newly generated information of the agricultural product to be traced to other common nodes in the agricultural product sales knowledge graph where the merchant management server 20a is located, such as the merchant management server 20b and the merchant management server 20c, according to the node identifiers of the other nodes in the agricultural product sales knowledge graph, the newly generated information of the agricultural product to be traced is verified by the other common nodes, and after the verification is completed, the newly generated information of the agricultural product to be traced is added to the agricultural product sales knowledge graph stored by the merchant management server 20 a. Similarly, when the agricultural product transaction related information in the offline commodity sales server 30a is sent to the merchant management server 20b or 20c, or when the agricultural product transaction related information in the offline commodity sales server 30c is sent to other scenarios such as the merchant management server 20b or 20c, the newly generated agricultural product information to be traced is also added to the agricultural product sales knowledge graph corresponding to the merchant management server 20 by the above method.

As can be seen from the above, the agricultural product information to be traced in the agricultural product sales knowledge map stores agricultural product transaction related information, then the first agricultural product state data in the agricultural product information to be traced is sent to the central server 10 through the merchant management server 20 at an initial time point, and the central server 10 generates and files an agricultural product information node after acquiring the first agricultural product state data; at a target time point, the merchant management server 20 sends the second agricultural product state data of the agricultural product information to be traced to the central server 10, and the central server 10 can determine whether the agricultural product transaction related information in the agricultural product information to be traced has industrial chain change by comparing the second agricultural product state data with the first agricultural product state data in the agricultural product central management knowledge map, so that by adopting the method and the system, not only can the structure of the agricultural product central management knowledge map be optimized, but also the tracing reliability of the agricultural product transaction related information stored in the agricultural product sales knowledge map after the structure is optimized is ensured.
Optionally, after obtaining the agricultural product archiving instruction sent by the merchant management server 20, the central server 10 may first perform the confirmation of the sales cooperation state on the first agricultural product state data in the agricultural product archiving instruction, that is, for the above steps S102 to S104, further provides the following specific implementation manners:
at the TimeA time point, the central server 10 obtains an agricultural product filing instruction sent by the merchant management server 20, and before filing first agricultural product state data of agricultural product information Bb to be traced, needs to determine that the sales cooperation state of the first agricultural product state data is stable, where the first agricultural product state data includes a supplier identifier Bb, a sales information identifier (first sales information identifier) corresponding to the supplier identifier Bb at the TimeA time point, and a sales information identifier summary ciphertext (first sales information identifier summary ciphertext) corresponding to the supplier identifier Bb at the TimeA time point;

according to a first sales information identification information summary ciphertext corresponding to a first provider identification Aa in historical agricultural product state data and a first sales information identification H corresponding to a provider identification Bb, the central server 10 can verify whether the first agricultural product state data is stable in a sales cooperation state, if the first sales information identification information summary ciphertext corresponding to the first provider identification Aa is equal to the first sales information identification information summary ciphertext, the central server 10 determines that the first agricultural product state data is stable in a sales cooperation state, and if the first sales information identification information summary ciphertext corresponding to the first provider identification Aa is not equal to the first sales information summary ciphertext, the central server 10 determines that the first agricultural product state data is unstable in a sales cooperation state; when the sales cooperation state of the first agricultural product state data is unstable, namely the situation that the agricultural product transaction related information of the agricultural product information Aa to be traced has been subjected to production chain change is verified, the central server 10 returns the first agricultural product state data archiving abnormal information and the situation information that the agricultural product transaction related information of the agricultural product information Aa to be traced undergoes the production chain change to the merchant management server 20, so that the merchant management server 20 stops preset archiving operation and executes sales cooperation state determination operation, namely the agricultural product information Aa to be traced is detected, and the method can comprise the steps of initiating a request for verifying the agricultural product information Aa to be traced to other consensus nodes on an agricultural product sales knowledge graph; if the sales cooperation state of the first agricultural product state data is stable, that is, it is verified that the agricultural product transaction related information of the agricultural product information Aa to be traced has not undergone industrial chain change, the node information data 2b of the agricultural product information node generated according to the first agricultural product state data is the first agricultural product state data.
If the mode of sending the archive indication of agricultural products to the central server 10 by the merchant management server 20 is the same as the mode described above, the central server 10 still verifies the sales cooperation state of the first agricultural product state data according to the above process after receiving the first agricultural product state data, and first determines the minimum supplier identifier in the first agricultural product state data, where the first agricultural product state data includes a supplier identifier Aa, a first sales information identifier corresponding to a TimeA time point supplier identifier Aa, a first sales information identifier digest ciphertext corresponding to a TimeA time point supplier identifier Aa, a supplier identifier Bb, a first sales information identifier corresponding to a TimeA time point supplier identifier Bb, a first sales information identifier digest ciphertext corresponding to a TimeA time point supplier identifier Bb, a first sales information identifier corresponding to a supplier identifier ccb, and a first sales information digest ciphertext corresponding to a time point supplier identifier ccc, determining a target agricultural product information node (associated agricultural product information containing agricultural product information to be traced Aa, namely agricultural product information to be traced Dd) in an agricultural product center management knowledge graph according to a supplier identifier Aa, acquiring historical agricultural product state data in the node information of the target agricultural product information node, and then acquiring a sales information identifier information summary ciphertext corresponding to a historical sales information identifier; and then verifying whether the first agricultural product state data is in a stable sales cooperation state according to the original sales information identification information digest cipher text in the first sales information identification corresponding to the TimeA time point supplier identification Aa and the sales information identification information digest cipher text corresponding to the historical sales information identification, wherein the subsequent process is similar to the process, and is not repeated one by one.
The first agricultural product state data verification is carried out before filing so as to ensure that the filed first agricultural product state data is legal, and the condition that the industrial chain change does not occur to the agricultural product transaction related information in the agricultural product sales knowledge map at the TimeA time point is proved.
Further, the embodiment of the invention provides an agricultural full-industry chain traceability example based on big data. The implementation can be performed by the following steps:

Specifically, the agricultural product information with the maximum generation timestamp is acquired from the agricultural product sales knowledge map and is used as an original sales information identifier, and a sales information identifier summary ciphertext of the original sales information identifier is used as an original sales information identifier summary ciphertext; generating the agricultural product information to be traced based on the original sales information identification information summary ciphertext and the agricultural product transaction related information; the generation timestamp in the agricultural product information to be traced is used for updating the maximum generation timestamp on the agricultural product sales knowledge map; broadcasting the agricultural product information to be traced to all consensus nodes on the agricultural product sales knowledge graph; and when determining that all the consensus nodes on the agricultural product sales knowledge graph reach consensus, adding the agricultural product information to be traced to the agricultural product sales knowledge graph.
The embodiment of the invention also provides another example of data archiving based on the agricultural product information chain. The merchant management server 20 obtains the transaction-related information of the agricultural products to be archived, which is sent by the offline commodity sales server 30, wherein the transaction-related information of the agricultural products to be archived includes the transaction-related information of the first agricultural product to be archived, the transaction-related information of the second agricultural product to be archived, … and the transaction-related information of the nth agricultural product to be archived, and assuming that the quantity of the transaction-related information of the agricultural products stored in each piece of information of the agricultural products to be archived (including the information Aa of the agricultural products to be archived and the information Bb of the agricultural products to be archived) in the agricultural product sales knowledge map is 100, the transaction-related information of the agricultural products to be archived from the first transaction-related information to the first transaction-related information of the agricultural products to be archived is stored in the information Ee of the agricultural products to be archived, and so on, the transaction-related information of the agricultural products from the seventh transaction-related to-zero transaction-related information of the agricultural products to be archived to the eighth transaction-related information of the agricultural products to be archived is stored in the information Bb of the agricultural products to be archived, the eighth to ninth to-be-archived agricultural product transaction related information is stored in the to-be-traced agricultural product information Cc; taking the generation process of the agricultural product information to be traced as an example, describing a detailed process of the generation of the agricultural product information to be traced, the merchant management server 20 acquires the seventh hundred agricultural product transaction related information to be archived, which is sent by the offline commodity sales server 30, firstly verifying the seventh hundred agricultural product transaction related information to be archived, after checking, storing the seventh hundred agricultural product transaction related information to be archived into a memory pool and updating the Tree, updating the timestamp of the Tree according to the timestamp of the acquired seventh hundred agricultural product transaction related information to be archived, and then calculating the information summary ciphertext of the seventh hundred agricultural product transaction related information to be archived by using the MD5 algorithm; the merchant management server 20 obtains the seventh hundred and two to-be-archived agricultural product transaction related information sent by the offline commodity sales server 30, obtains the information digest cipher text of the seventh hundred and two to-be-archived agricultural product transaction related information through the above process until the information digest cipher text of the eighth hundred to-be-archived agricultural product transaction related information is obtained through calculation, then stores the seventh hundred to-be-archived agricultural product transaction related information into the node information of the to-be-traced agricultural product information Bb, and generates the information digest cipher text corresponding to the to-be-sourced agricultural product information Bb according to the information digest cipher text of the seventh hundred to-be-archived agricultural product transaction related information, … and the information digest cipher text of the eighth to-be-archived agricultural product transaction related information, and the merchant management server 20 generates the information digest cipher text corresponding to the to-sourced agricultural product information Bb according to the sales information identification information digest cipher text of the to-traced agricultural product information Aa, Information summary ciphertext corresponding to the agricultural product information to be traced, and seventh hundred agricultural product transaction related information to be filed to eighth hundred agricultural product transaction related information to be filed generate agricultural product information to be traced, the agricultural product information to be traced, to be filed, is broadcast to other merchant management servers 20 in the agricultural product sales knowledge map, the agricultural product information to be traced, to be filed, is verified by the other merchant management servers 20, and the agricultural product information to be traced, to be filed, is added to the agricultural product sales knowledge map stored by the merchant management server 20 after verification is completed. Similarly, when the central server 10 acquires the transaction related information of the agricultural product to be archived, the newly generated agricultural product information node is added to the management knowledge graph of the agricultural product center through the above process.

The specific implementation method of step S202 can be referred to the description of step S101 in the corresponding embodiment.
Step S203, the merchant management server 20 obtains second agricultural product state data of the to-be-traced agricultural product information at a target time point from the agricultural product sales knowledge graph, and obtains the agricultural product information node from the agricultural product center management knowledge graph based on the second agricultural product state data; the target time point is greater than the initial time point.
Specifically, in the foregoing embodiment, the description of step S103 is that the merchant management server 20 sends the second agricultural product state data of the to-be-traced agricultural product information at the target time point to the central server 10, so that the central server 10 checks the to-be-traced agricultural product information; in this step, the merchant management server 20 actively acquires the agricultural product information nodes in the agricultural product center management knowledge graph through the central server 10, so as to check the agricultural product information to be traced; at a target time point, second agricultural product state data of agricultural product information to be traced is obtained, the second agricultural product state data comprises a second supplier identification (same as the first supplier identification) of the agricultural product information to be traced at the target time point and a second sales information identification information summary ciphertext corresponding to the second supplier identification, an agricultural product information node is obtained in an agricultural product center management knowledge graph according to the second supplier identification, the agricultural product information node is generated by a center server 10 at an initial time point according to first agricultural product state data of the agricultural product information to be traced, and the first agricultural product state data comprises the first supplier identification and the first sales information identification information summary ciphertext corresponding to the first supplier identification.

When the agricultural product information to be traced is traceable agricultural product information, the merchant management server 20 continues to execute preset archiving operation; when the to-be-traced agricultural product information is the non-traceable agricultural product information, the merchant management server 20 stops the preset filing operation and performs the tracing inspection operation.
The agricultural product information to be traced in the agricultural product sales knowledge graph in the embodiment of the invention can be used for storing agricultural product transaction related information, then the first agricultural product state data in the agricultural product information to be traced is sent to the central server 10 through the merchant management server 20 at the initial time point, and the central server 10 generates and files an agricultural product information node after obtaining the first agricultural product state data; at the target time point, the merchant management server 20 sends the second agricultural product state data of the agricultural product information to be traced (the second agricultural product state data is the agricultural product state data of the agricultural product information to be traced at the target time point) to the central server 10, and the central server 10 can identify whether the agricultural product transaction related information in the agricultural product information to be traced has industrial chain change or not by comparing the second agricultural product state data with the first agricultural product state data in the agricultural product central management knowledge map.
In order to more clearly describe the scheme provided by the embodiment of the present invention, the embodiment of the present invention further provides the following examples.
S301, obtaining agricultural product tracing instructions.
The agricultural product tracing instruction identifies the merchant management server 20 which transmits and receives agricultural product tracing data with the central server 10.
For example, an agricultural product tracing data request may be directly obtained, for example, a user selects the merchant management server 20 that needs to receive and transmit agricultural product tracing data with the central server 10 through the data interaction application program to trigger generation of an agricultural product tracing instruction, the agricultural product tracing instruction may carry information of the merchant management server 20, the agricultural product tracing instruction is sent to the agricultural product tracing data processing device, and the agricultural product tracing data processing device may directly receive the agricultural product tracing instruction. When the number of the merchant management servers 20 which need to receive and transmit the agricultural product traceability data with the central server 10 is large, the agricultural product traceability instruction can be indirectly obtained, for example, a user selects information of a plurality of merchant management servers 20 which need to receive and transmit the agricultural product traceability data with the central server 10 through a data interaction application program, an information set of the merchant management server 20 is generated, the information set of the merchant management server 20 is stored in a third-party database, a storage address of the information set of the merchant management server 20 is obtained, the agricultural product traceability instruction is generated, the storage address is added to the agricultural product traceability instruction, the agricultural product traceability instruction added with the storage address is sent to the agricultural product traceability data processing device, the agricultural product traceability data processing device extracts the storage address after receiving the agricultural product traceability instruction, and acquiring the information set of the merchant management server 20 in a third-party database according to the extracted storage address.
It should be noted that, the merchant management server 20 may also receive an agricultural product traceability instruction. The specific receiving method is the same as the receiving method of the host of the center server 10.
S302, according to the agricultural product traceability indication, a central cache is divided in the central server 10, and the merchant management server 20 is enabled to divide a merchant cache in the merchant management server 20 and the central server 10.
The central cache and the merchant cache both belong to a cache space, the cache space may be a space passing security authorization, and the narrow understanding may be an area on the CPU. The function of this block area is to provide a more secure space for the execution of data and code and to ensure their confidentiality and integrity. The cache space is protected by hardware devices. Other applications or processes in the device cannot directly access the cache space.
For example, after the host computer of the central server 10 receives the agricultural product tracing instruction, a cache space process is divided, the cache space process is used for initializing a Trusted Execution Environment in a hardware area of the central server 10, and a space under the TEE Environment can be called as a central cache. Correspondingly, after the merchant management server 20 receives the agricultural product tracing instruction, the merchant management server 20 may also divide a cache space process, so as to initialize another TEE environment in the hardware area of the central server 10 of the merchant management server 20, and use the space in the TEE environment as a merchant cache.
Optionally, after the central cache and the merchant cache are divided, the cache ready conditions of the central cache and the merchant cache need to be checked, and whether the cache ready conditions of the verification central cache and the merchant cache meet a preset verification condition or not may be verified in a specific verification manner as follows:
vectorizing the cache attribute of the central cache, and sending the first cache vector obtained by vectorization to the merchant management server 20, so that the merchant management server 20 checks the cache readiness condition of the central cache according to the first cache vector, receives the cache readiness condition check status identifier of the central cache sent by the merchant management server 20 and the second cache vector of the cache attribute of the merchant cache, determines that the cache readiness condition check status identifier of the merchant cache passes the check when the second cache vector is the same as the preset cache vector, and determines that the central cache and the merchant cache conform to the preset working state when the cache readiness condition check status identifiers of the central cache and the merchant cache both pass the check.
For example, software code information of the central cache is obtained, vectorization processing is performed on the software code information to obtain a first cache vector, the first cache vector is sent to the merchant management server 20, so that the merchant management server 20 compares the first cache vector with a preset cache vector, if the preset cache vector is the same as the first cache vector, the merchant management server 20 determines that the cache ready condition of the central cache passes the check, and if the preset cache vector is not the same as the first cache vector, the merchant management server 20 determines that the cache ready condition of the central cache fails the verification. In the process of checking the central cache, the merchant management server 20 may further perform vectorization processing on the software code information cached by the merchant to obtain a second cache vector. The merchant management server 20 sends the second cache vector and the cache ready condition check status flag of the central cache to the central server 10, the host of the central server 10 compares the second cache vector with the preset cache vector, and when the second cache vector is the same as the preset cache vector, the cache ready condition check status flag of the merchant cache is determined to be a pass check. When the cache ready condition check state marks of the central cache and the merchant cache are both passed, determining that the cache ready conditions of the central cache and the merchant cache reach a preset working state.
S303, when the cache ready conditions of the central cache and the merchant cache reach a preset working state, constructing an interaction channel and a preset security code between the central cache and the merchant cache.
Wherein, the interaction channel may be a channel for securely transmitting data, and the interaction channel is used for connecting the central cache of the central server 10 and the merchant cache of the merchant management server 20.
For example, when the cache ready conditions of the central cache and the merchant cache reach a preset working state, a central server 10 interface of the central cache and a merchant server interface of the merchant cache are obtained, a preset secure transmission protocol is adopted, a data transmission channel is constructed between the central server 10 interface and the merchant server interface, for example, the data transmission channel may be constructed based on a Transport Layer cache ready condition protocol (TLS), and the data transmission channel is used as an interaction channel between the central cache and the merchant cache. The security code file is preset with the merchant management server 20 through the interaction channel to generate a preset security code between the central cache and the merchant cache. For example, a key file is exchanged with the merchant management server 20 through Diffie-Hellman (key exchange protocol) in the interaction channel, a data encryption security Code between the central cache and the merchant cache is generated according to the exchanged key file, a session-extended information digest operation is performed on the data encryption security Code to obtain a single-key encryption security Code required for symmetric encryption and a Message Authentication security Code (HMAC) used for generating a Message Authentication Code, and the data encryption security Code, the single-key encryption security Code and the Message Authentication security Code are used as preset security codes and stored in the central cache and the merchant cache.
Wherein the preset security code generated by the host of the central server 10 and the preset security code generated by the merchant management server 20 may be the same.
S304, agricultural product traceability data are received and transmitted with the merchant management server 20 through the interaction channel and the preset security code, and an agricultural product traceability statistical table between the central server 10 and the merchant management server 20 is calculated based on the interactive agricultural product traceability data.
For example, the data digests of the agricultural product traceability data stored in the data digests respectively can be exchanged with the merchant management server 20 through the interaction channel, where the data digests include agricultural product data volume of the agricultural product traceability data, the agricultural product data volume of the agricultural product traceability data of the merchant management server 20 is compared with the agricultural product data volume of the archived agricultural product traceability data of the central server 10 to determine the type of the merchant management server 20, according to the interaction channel, the central cache and the preset security code, a data transmission protocol corresponding to the type of the merchant management server 20 is adopted to perform an agricultural product traceability statistical table with the merchant management server 20, and an agricultural product traceability statistical table between the central server 10 and the merchant management server 20 is calculated based on the interaction agricultural product traceability data, which specifically may be as follows:
and S1, exchanging the data abstracts of the agricultural product traceability data stored respectively with the merchant management server 20 through the interactive channel.
The data summary includes an agricultural product data volume of the agricultural product traceability data filed by the central server 10 and an agricultural product data volume of the agricultural product traceability data to be filed by the merchant management server 20, for example, the data volume may be data information such as a data scale in the agricultural product traceability data filed and the agricultural product traceability data to be filed.
For example, a data abstract of the archived agricultural product traceability data of the central server 10 is obtained, the archived agricultural product traceability data is sent to the merchant management server 20, and the data abstract of the agricultural product traceability data to be archived, which is sent by the merchant management server 20, is received, so that the host of the central server 10 and the merchant management server 20 interact with the data abstract of the agricultural product traceability data stored respectively.
And S2, comparing the agricultural product data volume of the agricultural product traceability data to be archived with the agricultural product data volume of the agricultural product traceability data already archived to determine the type of the merchant management server 20.
For example, the agricultural product data volume of the agricultural product traceability data to be archived and the repeated agricultural product data volume of the agricultural product traceability data already archived may be calculated, the repeated agricultural product data is compared with a preset repetition threshold, when the repeated agricultural product data does not exceed the preset repetition threshold, the type of the merchant management server 20 may be determined to be the internal merchant management server 20, and when the repeated agricultural product data exceeds the preset repetition threshold, the type of the merchant management server 20 may be determined to be the outsourced merchant management server 20.
The internal merchant management server 20 may be understood as a merchant management server 20 under the same company flag as the agricultural product traceability data of the central server 10 host, and the outsourced merchant management server 20 may be understood as a merchant management server 20 under a different company flag as the agricultural product traceability data of the central server 10 host.
And S3, according to the interaction channel, the central cache and the preset security code, adopting a data transmission protocol corresponding to the type of the merchant management server 20 to receive and transmit agricultural product traceability data with the merchant management server 20, and calculating an agricultural product traceability statistical table between the central server 10 and the merchant management server 20 based on the interactive agricultural product traceability data.
For example, according to the type of the merchant management server 20, a target merchant management server 20 for receiving and sending agricultural product traceability data with the central server 10 is screened out from the merchant management server 20, a data transmission protocol of the target merchant management server 20 is determined, according to the data transmission protocol and a preset security code, agricultural product traceability data is received and sent by the archived agricultural product traceability data and agricultural product traceability data to be archived of the target merchant management server 20 through an interaction channel and a central cache, and an agricultural product traceability statistical table between the central server 10 and the merchant management server 20 is calculated based on the interacted agricultural product traceability data, which may specifically be as follows:
and C1, screening out target merchant management servers 20 used for agricultural product traceability data transceiving with the central server 10 from the merchant management servers 20 according to the types of the merchant management servers 20, and determining a data transmission protocol of the target merchant management servers 20.
For example, when the merchant management server 20 is the internal merchant management server 20, the internal merchant management server 20 is used as the target merchant management server 20 for performing agricultural product traceability data transceiving with the central server 10, and the data transmission protocol of the target merchant management server 20 is determined to be the first data transmission protocol. When the merchant management server 20 is the outsourced merchant management server 20, a preset number of outsourced merchant management servers 20 are screened out of the outsourced merchant management servers 20 as target merchant management servers 20.
The third data transmission protocol may be a first data transmission protocol with the internal merchant management server 20, and after the first data transmission protocol is completed, a second data transmission protocol with the outsourced merchant management server 20.
And C2, according to the data transmission protocol and the preset security code, performing agricultural product traceability data receiving and sending on the archived agricultural product traceability data and the agricultural product traceability data to be archived of the target merchant management server 20 through the interaction channel and the central cache, and calculating an agricultural product traceability statistical table between the central server 10 and the merchant management server 20 based on the interactive agricultural product traceability data.
For example, when the data transmission protocol is a first data transmission protocol, agricultural product traceability data is received and transmitted between the archived agricultural product traceability data corresponding to the ratio and the agricultural product traceability data to be archived of the internal merchant management server 20 through the interaction channel and the preset security code, traceability records between the archived agricultural product traceability data and the agricultural product traceability data to be archived of the internal merchant management server 20 are calculated in the central cache, so as to obtain an agricultural product traceability statistical table between the central server 10 and the merchant management server 20, when the data transmission protocol is a second data transmission protocol, candidate agricultural product traceability data sent by the outsourced merchant management server 20 is received, the agricultural product traceability statistical table between the central server 10 and the merchant management server 20 is determined according to the candidate agricultural product traceability data, when the data transmission protocol is a third data transmission protocol, the agricultural product traceability data sending and receiving method comprises the steps of carrying out agricultural product traceability data sending and receiving on the archived agricultural product traceability data corresponding to the ratio and the agricultural product traceability data to be archived of the internal merchant management server 20, calculating traceability records between the archived agricultural product traceability data and the agricultural product traceability data to be archived of the internal merchant management server 20 in a central cache to obtain an agricultural product traceability initial statistical table, receiving the agricultural product traceability data to be archived sent by the outsourcing merchant management server 20, and determining the agricultural product traceability statistical table between the central server 10 and the merchant management server 20 according to the agricultural product traceability initial statistical table and the agricultural product traceability data to be archived sent by the outsourcing merchant management server 20. Specifically, the following may be mentioned:
(1) when the data transmission protocol is the first data transmission protocol, agricultural product traceability data is received and transmitted by the corresponding ratio of the archived agricultural product traceability data and the agricultural product traceability data to be archived of the internal merchant management server 20 through the interaction channel and the preset security code, and traceability records between the archived agricultural product traceability data and the agricultural product traceability data to be archived of the internal merchant management server 20 are calculated in the central cache, so that an agricultural product traceability statistical table between the central server 10 and the merchant management server 20 is obtained.
For example, when the data transmission protocol is the first data transmission protocol, agricultural product traceability data of a target quantity proportion can be screened from the archived agricultural product traceability data to serve as target archived agricultural product traceability data, the target archived agricultural product traceability data is sent to the internal merchant management server 20 through an interaction channel and a preset security code, the target agricultural product traceability data to be archived sent from the internal merchant management server 20 is received, traceability records of the remaining archived agricultural product traceability data which are not sent to the internal merchant management server 20 and the target agricultural product traceability data to be archived are calculated in a central cache to obtain a first agricultural product traceability initial statistical table, the first agricultural product traceability initial statistical table is sent to the internal merchant management server 20, and a second agricultural product traceability initial statistical table sent from the internal merchant management server 20 is received, and fusing the first agricultural product traceability initial statistical table and the second agricultural product traceability initial statistical table to obtain an agricultural product traceability statistical table between the central server 10 and the merchant management server 20. Specifically, the following may be used:
and B1, screening agricultural product traceability data with a target quantity proportion from the archived agricultural product traceability data to serve as target archived agricultural product traceability data, and sending the target archived agricultural product traceability data to the internal merchant management server 20 through an interaction channel and a preset security code.
For example, when the data transmission protocol is the first data transmission protocol, according to the data abstract of the internal merchant management server 20, a target quantity ratio of agricultural product traceability data transceiving between the central server 10 and the internal merchant management server 20 and a binning quantity of card binning for storing agricultural product traceability data are determined, for example, according to the quantity of the internal merchant management servers 20, a target quantity ratio of agricultural product traceability data transceiving between the central server 10 and the internal merchant management server 20 may be determined, for example, the quantity of the internal merchant management servers 20 is n, and a host of the central server 10 interacting with the internal merchant management servers is added, in order to ensure that the target quantity ratio of interaction between each merchant management server 20 is the same, so that the target quantity ratio may be determined to be 1/(n + 1). Then, the box dividing number of card side sub-boxes for storing agricultural product traceability data is determined according to the maximum security memory of the central cache and the merchant cache and the agricultural product traceability data volume for interaction, for example, the security memory of the central cache and the merchant cache is 256M, each card side sub-box can store 20M at most, the maximum data in the agricultural product traceability data volume for user interaction is 400M, and the target quantity ratio is 1/5, for example, the agricultural product data volume of the agricultural product traceability data for interaction in the central cache and the merchant cache can be 80M at most, so that the box dividing number (BN) of the card side sub-boxes can be determined to be 4, and the box dividing number is stored in the region of the central server 10 outside the cache space. The method comprises the steps that central card side sub-boxes corresponding to the sub-box number are divided in the area of a central server 10 except a central cache, first safety maintenance operation is conducted on filed agricultural product traceability data through data encryption safety codes, the agricultural product traceability data of the central server 10 after the first safety maintenance operation are cut into sub-agricultural product traceability data corresponding to the sub-box number, the sub-agricultural product traceability data are determined to be stored in the sub-box number of the central card side sub-box, and the sub-agricultural product traceability data are stored in the central card side sub-boxes corresponding to the sub-box number.
The method for processing agricultural product traceability data includes the steps that card square sub-boxes are adopted, so that paging does not occur when agricultural product traceability data are processed, and therefore the minimum sub-box number needs to be determined according to the upper limit of a safe memory.
According to the principle of box separation, in the transaction process of two parties, if the two parties have the same original agricultural product traceability data, the same agricultural product traceability data can exist in the same box separation after hash and box separation operation, and therefore the agricultural product traceability data stored in the chi-square box separation by the two parties can be safely compared.
B2, receiving the traceability data of the target agricultural product to be archived, sent by the internal merchant management server 20, and calculating the traceability records of the traceability data of the remaining archived agricultural products and the traceability data of the target agricultural product to be archived, which are not sent to the internal merchant management server 20, in the central cache to obtain a first agricultural product traceability initial statistical table.
For example, the traceability data of the target agricultural product to be archived, which is sent by the internal merchant management server 20, is received, in the central cache, the integrity of the traceability data of the target agricultural product to be archived is checked by using the message authentication security code, the integrity verification is mainly used for verifying whether the traceability data of the target agricultural product to be archived is complete, the verification method can be used for calculating the HMAC by using the message authentication security code, the HMAC is compared with the authentication code at the beginning of the traceability data of the target agricultural product to be archived, if the HMAC is consistent with the authentication code at the beginning of the traceability data of the target agricultural product to be archived, the integrity of the traceability data of the target agricultural product to be archived can be determined to pass the verification, otherwise, the integrity of the traceability data of the target agricultural product to be archived is determined to not pass the verification, and at this time, the traceability data of the target agricultural product to be archived is discarded.
B3, sending the first agricultural product traceability initial statistical table to the internal merchant management server 20, and receiving the second agricultural product traceability initial statistical table sent by the internal merchant management server 20.
The second agricultural product traceability initial statistical table may be a traceability record between the remaining agricultural product traceability data to be archived, which is not sent to the central server 10 and is calculated by the internal merchant management server 20, and the target archived agricultural product traceability data.
For example, when the central server 10 host sends the trace-to-source data of the target agricultural product to be archived to the internal merchant management server 20, the internal merchant management server 20 calculates the trace-to-source record between the trace-to-source data of the remaining agricultural product to be archived, which is not sent to the central server 10, and the trace-to-source data of the target archived agricultural product in the same calculation manner as the central server 10 host, so as to obtain the second agricultural product trace-to-source initial statistical table. The internal merchant management server 20 and the central server 10 host interact with the agricultural product traceability initial statistical table which is calculated by the internal merchant management server 20 and the central server through an interaction channel.
And B4, fusing the first agricultural product traceability initial statistical table and the second agricultural product traceability initial statistical table to obtain an agricultural product traceability statistical table between the central server 10 and the merchant management server 20.
For example, a first agricultural product traceability initial statistical table and a second agricultural product traceability initial statistical table are merged, for example, the first agricultural product traceability initial statistical table and the second agricultural product traceability initial statistical table are compared, if the first agricultural product traceability initial statistical table and the second agricultural product traceability initial statistical table do not have the same agricultural product traceability data, the agricultural product traceability data in the two agricultural product traceability initial statistical tables are directly combined into a new traceability record to obtain the agricultural product traceability statistical table between the central server 10 and the merchant management server 20, if the same agricultural product traceability data exists in the first agricultural product traceability initial statistical table and the second agricultural product traceability initial statistical table, the same agricultural product traceability data is calculated as an agricultural product traceability data and is combined with other different agricultural product traceability data, and obtaining an agricultural product traceability statistical table between the central server 10 and the merchant management server 20.

When the integrity of the first candidate agricultural product tracing data passes verification, the first candidate agricultural product tracing data is decrypted in the central cache by adopting a single-key encryption security code, and a tracing record between the decrypted first candidate agricultural product tracing data and the filed agricultural product tracing data is calculated in the central cache to obtain a target agricultural product tracing statistical table. The target agricultural product traceability statistical table is used as an agricultural product traceability statistical table between the central server 10 and the merchant management server 20.
