Background technique

In the related technology, before meat products enter the market from farms or slaughterhouses, they need to undergo animal quarantine by a certification agency. After passing the quarantine, the certification agency will issue a paper certificate, which will then enter the market circulation link with the meat products.

technical problem

In the market circulation link, each circulation requires the issuing agency to re-issue a paper certificate, which increases the printing, storage and management costs of paper documents and raises social labor costs. In addition, the staff of the issuing agency repeatedly issues paper certificates for different owners of the same batch of meat products, resulting in repeated waste of social resources and increased carbon emissions and environmental pollution. In addition, since it is difficult to identify the authenticity of paper certificates, it increases the management and identification difficulties of regulatory authorities.

Best Mode for Carrying Out the Invention

The application embodiment provides a method for managing an electronic certificate for a target object, and the execution subject of the method can be a traceability system. Figure 2 is a flow chart of a method for managing an electronic certificate for a target object in an embodiment of the present application. As shown in Figure 2, the method includes:

Step S201: Based on the electronic authentication data corresponding to the target object received from the certificate issuance system, determine the source entity corresponding to the target object and send a first confirmation request to the source entity; the electronic authentication data includes structured information and electronic certificate corresponding to the target object, and the source entity is the entity that initiates the authentication request to the certificate issuance system.

In the embodiment of the present application, the target object may be a specific commodity that needs to be certified for compliance by a certificate issuing agency. The certificate issuing agency is an agency that has relevant qualifications to inspect and certify specific commodities. In response to the certification request initiated by the source entity to the certificate issuing system, the certificate issuing system inspects and certifies the specific commodity, issues a compliance certificate for the specific commodity that meets the certification conditions, and sends the electronic certification data related to the compliance certificate to the traceability system.

Among them, when the target object is a meat product, the source entity can be a farm, slaughterhouse, etc. In addition, when the target object is other specific commodities, the source entity can also be a manufacturer, etc.

The structured information included in the electronic authentication data specifically includes the commodity attribute information of the target object, the subject-related information corresponding to the target object, and the batch purchase information of the target object. Among them, the commodity attribute information may include the product name, quantity and unit, weight, and production unit name and address of the target object. The subject-related information may include the subject's identification code, registration code, and qualification certificate. The electronic certificate included in the electronic authentication data may specifically be an electronic image of the compliance certificate corresponding to the target object. For example, in the case where the target object is a meat product, the electronic certificate may specifically be an electronic image of the "Animal Inspection and Quarantine Certificate".

Exemplarily, the issuing system exchanges data with the traceability system through the Application Program Interface (API). Electronic authentication data can be encrypted and transmitted using the MD5 Message-Digest Algorithm. The signature verification rule specifically involves double verification of the secret key and submission timestamp provided by the traceability system to prevent the electronic authentication data from being tampered with or forged, and to ensure the authenticity and security of the electronic authentication data.

Exemplarily, after receiving the electronic authentication data, the traceability system can match the subject credit code contained in the electronic authentication data with the merchant credit code registered in the traceability system, determine the source subject's registered account on the traceability system according to the matching result, and send a first confirmation request to the source subject. Among them, the first confirmation request may include the electronic authentication data corresponding to the target object, that is, send the electronic authentication data to the source subject's registered account.

Step S202: Based on the source entity’s confirmation operation on the electronic authentication data, generate the source entity’s original batch reporting information.

For example, after the source entity logs in to the traceability system, it can check the received electronic certification data. After confirming the electronic certification data, the circulation supervision platform generates the original batch filing information of the source entity. The original batch filing information specifically includes the original batch filing time and relevant information of the source entity.

Step S203: Associate the electronic authentication data with the original batch reporting information to obtain the electronic certificate corresponding to the target object in the original batch.

Exemplarily, the specific form of the electronic certificate can be a QR code, barcode or other coding form. The electronic certificate is used to display the relevant information of the target object in the original batch when it is identified, and may include the commodity attribute information of the target object, relevant information of the electronic certificate and relevant information of the source entity corresponding to the target object.

It should be noted that in the embodiment of the present application, the electronic certificate can be used as a compliance certificate and traceability basis for the target object in the subsequent circulation link. For example, as a compliance certificate, the electronic certificate can be used to indicate the certificate number of the electronic certificate corresponding to the target object and the query website information of the issuing system; as a traceability basis, the electronic certificate can be used to indicate the relevant information of the source entity, product attribute information, and batch purchase information.

Step S204: In response to the query request initiated by the query subject for the electronic certificate, the query subject is provided with a query service corresponding to the query authority of the query subject through the query interface. Different query subjects have different query authorities, and the query services corresponding to the query authorities are also different.

In the embodiment of the present application, the query subject may include the issuing institution, the circulation subject of the target object in the subsequent circulation link, and the consumer, etc. The query request can be initiated by the query subject on the traceability system. According to the query request received, the query authority corresponding to the query subject is determined, and then the query interface corresponding to the query authority is called to provide the query subject with the corresponding query service. The query interface is used for the query subject to access the database storing the electronic certificate so that the query subject can query the electronic certificate corresponding to the target object in the database. More specifically, different query subjects have different query authorities, that is, different access rights to all the information contained in the electronic certificate of the target object. For example, the query authority of the issuing institution includes the access right to the original batch filing information and the electronic certificate of the target object; the query authority of the circulation subject and the consumer is limited to the access right to the electronic certificate of the target object. For query subjects with different access rights, corresponding query services are provided to different query subjects through different query interfaces.

Therefore, while meeting the query needs of different query subjects for the electronic credentials of the target object, transparent and public management of the electronic credentials of the target object is achieved, and corresponding query services can be selectively provided for query subjects with different query permissions, taking into account the confidentiality requirements of the commercial secrets involved in the target object.

According to the management method of the electronic certificate for the target object of the embodiment of the present application, by using the electronic certificate generated by the target object in the original batch as the compliance proof of the target object, paperless supervision of the target object is achieved, the printing cost of paper certificates is reduced, the storage and management cost of paper documents is reduced, the use and waste of paper resources are reduced, and carbon emissions and environmental pollution are effectively reduced. Secondly, by using the electronic certificate generated by the target object in the original batch as the basis for tracing the target object, the problem that the paper certificate can be forged, resulting in the inability to trace or the high cost of tracing is effectively solved, so that the authentication data of the target object becomes transparent, visible, checkable and traceable in the issuance link.

Embodiments of the present invention

In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

In order to more clearly demonstrate the management method of the electronic credential for the target object provided in the embodiment of the present application, the application scenario of the management method of the electronic credential for the target object provided in the embodiment of the present application is first introduced. The management method of the electronic credential for the target object provided in the embodiment of the present application can be applied to the specific scenario of supervising the compliance of the target object before the target object enters the market circulation and during the market circulation process.

FIG1 is a schematic diagram of a scenario of a method for managing electronic credentials of a target object according to an embodiment of the present application. The application scenario of the method for managing electronic credentials of a target object provided in an embodiment of the present application will be specifically introduced below in conjunction with FIG1 .

In this scenario, the execution subject of the management method of the electronic certificate for the target object of the embodiment of the present application can be a distributed server, specifically including a traceability system and an issuance system. The target object can be an animal or an animal product, specifically a meat product. The traceability system interacts with the issuance system for data, wherein the issuance agency corresponding to the issuance system can specifically be an animal health supervision agency, and the animal health supervision agency assigns official veterinarians to quarantine the target object, such as animals or animal products, in accordance with the relevant laws and regulations, and issue quarantine certificates and apply quarantine marks to obtain the electronic authentication data of the target object, and then send the electronic authentication data to the traceability system through the issuance system.

It is understandable that the electronic authentication data is used to indicate the compliance of the target object. The electronic authentication data can specifically be the relevant electronic data of other compliance certification documents such as the "Animal Quarantine Certificate" or the "Meat Inspection and Quarantine Certificate", including the structured information of the target object and the electronic image data of the compliance certification document. Among them, the structured information of the target object can include the subject information corresponding to the target object and the attribute description information of the target object (such as type, quantity and unit, purpose, transportation information, etc.), and the electronic image data of the compliance certification document is stamped with the electronic seal of the issuing institution, which has the same legal effect as the signature on the paper compliance certification document.

For the compliance verification link before the target object enters the market, the traceability system receives the electronic authentication data of the target object from the issuance system and sends the electronic authentication data to the source entity. After the source entity confirms the electronic authentication data on the traceability system, it generates the original batch filing information and sends the usage status of the electronic authentication data to the issuance system. The traceability system generates the electronic certificate corresponding to the target object under the original batch based on the electronic certificate contained in the electronic authentication data and the original batch filing information.

For the circulation link of the target object after entering the market, when the target object circulates from the upstream entity to the downstream entity, the upstream entity performs the circulation operation on the traceability system, generates a record to be confirmed and sends it to the downstream entity. Among them, the record to be confirmed specifically includes the transaction information of the target object under the circulation batch (such as the type, quantity and origin of the target object) and the electronic certification data. After the downstream entity confirms the record to be confirmed on the traceability system, the circulation batch reporting information is generated. The traceability system generates the electronic certificate of the target object under the current circulation batch based on the circulation reporting information and electronic certification data of the target object under the current circulation batch.

During the circulation process of the target object after entering the market, the target object can be circulated in multiple batches. Continuing with Figure 1, the target object can be distributed in batches by the source entity to circulation entities A1 and A2; circulation entity A1 can further distribute the target object to circulation entities B1 and B2; circulation entity B2 can also further distribute the target object to circulation entities C1 and C2. Among them, for each distribution circulation, the traceability system generates electronic certificates for the corresponding circulation batches.

Furthermore, the traceability system associates the electronic certificates corresponding to the target object in the original batch and each circulation batch according to the electronic certificate corresponding to the target object, obtains the traceability chain and stores it. The issuing system can query the traceability chain corresponding to the electronic authentication data of the target object stored in the database of the traceability system by sending a query request to the traceability system.

It is understandable that the electronic certificate can be used as a compliance certificate and traceability basis for the target object in the circulation link. For example, as a compliance certificate, the electronic certificate can be used to indicate the paperless animal quarantine certificate number corresponding to the target object and the query website information of the certificate issuance system; as a traceability basis, the electronic certificate can be used to indicate subject-related information, commodity attribute information, and batch purchase information.

It should be noted that the above-mentioned application scenario of the management method of electronic credentials for target objects provided in the embodiments of the present application is to facilitate the understanding of the management method of electronic credentials for target objects provided in the embodiments of the present application, and is not intended to limit the management method of electronic credentials for target objects provided in the embodiments of the present application. The management method of electronic credentials for target objects provided in the embodiments of the present application can also be used for other specific commodities that need to be verified for compliance by the issuing institution. For example, the target object can be other agricultural and sideline products such as vegetables or dairy products, or other products such as clothing and electrical appliances. Specifically, the application scenario of the management method of electronic credentials for target objects provided in the embodiments of the present application is not specifically limited.

The application embodiment provides a method for managing electronic credentials for a target object, and the execution subject of the method can be a traceability system. Figure 2 is a flow chart of a method for managing electronic credentials for a target object in an embodiment of the present application. As shown in Figure 2, the method includes: Step S201: Based on the electronic authentication data corresponding to the target object received from the certificate issuance system, determine the source subject corresponding to the target object and send a first confirmation request to the source subject; the electronic authentication data includes structured information and an electronic certificate corresponding to the target object, and the source subject is the subject that initiates the authentication request to the certificate issuance system.

In the embodiment of the present application, the target object may be a specific commodity that needs to be certified for compliance by a certification agency. The certification agency is an institution that has relevant qualifications to inspect and certify specific commodities. In response to the certification request initiated by the source entity to the certification system, the certification system inspects and certifies the specific commodity, issues a compliance certificate for the specific commodity that meets the certification conditions, and sends the electronic certification data related to the compliance certificate to the traceability system.

The structured information included in the electronic certification data specifically includes the commodity attribute information of the target object, the subject-related information corresponding to the target object, and the batch purchase information of the target object. Among them, the commodity attribute information may include the product name, quantity and unit, weight, and production unit name and address of the target object. The subject-related information may include the subject's identification code, registration code, and qualification certificate. The electronic certificate included in the electronic certification data may specifically be an electronic image of the compliance certificate corresponding to the target object. For example, in the case where the target object is a meat product, the electronic certificate may specifically be an electronic image of the "Animal Inspection and Quarantine Certificate".

Exemplarily, after receiving the electronic authentication data, the traceability system can match the subject credit code contained in the electronic authentication data with the merchant credit code registered in the traceability system, determine the source subject's registered account on the traceability system based on the matching result, and send a first confirmation request to the source subject. The first confirmation request may include the electronic authentication data corresponding to the target object, that is, sending the electronic authentication data to the source subject's registered account.

Step S202: Based on the source entity's confirmation operation on the electronic authentication data, the source entity's original batch reporting information is generated.

For example, after the source entity logs in to the traceability system, it can check the received electronic authentication data. After confirming the electronic authentication data, the circulation supervision platform generates the original batch filing information of the source entity. The original batch filing information specifically includes the original batch filing time and relevant information of the source entity.

Step S203: Associate the electronic authentication data with the original batch reporting information to obtain the electronic certificate corresponding to the target object under the original batch.

It should be noted that in the embodiment of the present application, the electronic certificate can be used as a compliance certificate and traceability basis for the target object in the subsequent circulation links. For example, as a compliance certificate, the electronic certificate can be used to indicate the certificate number of the electronic certificate corresponding to the target object and the query website information of the issuing system; as a traceability basis, the electronic certificate can be used to indicate the relevant information of the source entity, product attribute information, and batch purchase information.

According to the management method of the electronic certificate for the target object in the embodiment of the present application, by using the electronic certificate generated by the target object in the original batch as the compliance proof of the target object, paperless supervision of the target object is achieved, the printing cost of paper certificates is reduced, the storage and management cost of paper documents is reduced, the use and waste of paper resources are reduced, and carbon emissions and environmental pollution are effectively reduced. Secondly, by using the electronic certificate generated by the target object in the original batch as the basis for tracing the target object, the problem that the paper certificate can be forged, resulting in the inability to trace or the high cost of tracing is effectively solved, so that the authentication data of the target object becomes transparent, visible, checkable and traceable in the issuance link.

In one possible implementation, as shown in Figure 3, the management method of the electronic certificate for the target object of the embodiment of the present application may also include the following steps: Step S301: In response to the flow operation on the target object, determine the downstream entity corresponding to the flow operation and send a second confirmation request to the downstream entity.

In the embodiment of the present application, the transfer operation includes a first transfer operation initiated by the source subject on the target object, and the first transfer operation is used to transfer the target object in whole or in batches to the first downstream subject corresponding to the source subject. In addition, the transfer operation may also include a second transfer operation initiated by the first downstream subject on the target object, and the second transfer operation is used to transfer the target object in whole or in batches to the second downstream subject corresponding to the first downstream subject, and so on.

It is understandable that for the circulation chain formed by multiple subjects involved in the circulation process of the target object, there can be multiple circulation subjects between the source subject and the terminal subject. For example, in the case where the target object is a meat product, the source subject may include farms, slaughterhouses, etc.; the circulation subject may include dealers, wholesalers or distributors, etc.; the terminal subject may include canteens, schools, farmers' market merchants, supermarkets, catering stores or fresh food stores, etc., whose main business is directly facing market consumers. According to the circulation direction of the target object between different subjects in the circulation chain, the upstream subject and the corresponding downstream subject involved in the target object in a single circulation process can be determined, among which the upstream subject can specifically be the source subject or any circulation subject.

Exemplarily, the circulation operation can be initiated by the upstream subject logging into the traceability system when performing the circulation operation. When the upstream subject initiates the circulation operation on the target object, the traceability system generates relevant information about the circulation operation, including relevant information of the downstream subject corresponding to the circulation operation and the circulation attribute information of the target object under the current batch. Among them, the circulation attribute information of the target object may include the commodity attribute information of the target object, the quantity and unit of the target objects involved in this circulation, the time when the circulation occurs, and other information. According to the relevant information of the downstream subject, the account information of the downstream subject on the traceability system is determined, and a first reporting request is sent to the downstream subject. Among them, the first reporting request specifically includes the electronic certificate corresponding to the upstream subject and the relevant information of the current batch circulation operation.

Step S302: Based on the downstream entity’s confirmation operation on the target object, generate the downstream entity’s circulation batch reporting information.

For example, after logging into the traceability system, the downstream entity can check the electronic voucher corresponding to the upstream entity and the relevant information of the current batch circulation operation. After the confirmation operation, the circulation supervision platform generates the circulation batch reporting information of the downstream entity. Among them, the circulation batch reporting information may include the circulation attribute information of the target object, the circulation batch reporting time, and the relevant information of the downstream entity.

Step S303: Associate the circulation batch reporting information with the electronic certificate to obtain the electronic certificate corresponding to the target object in the current circulation batch.

Exemplarily, the specific form of the electronic certificate can be a QR code, barcode or other coding form. The electronic certificate is used to display relevant information of the target object in the current circulation batch when it is identified, and may include circulation batch reporting information and related information of the electronic certificate.

In addition, in an embodiment of the present application, the electronic certificates generated by the target object in the original batch and different circulation batches can also be sent to the user terminal of the corresponding subject, the regulatory agency terminal, the public web page, etc.

According to the above implementation method, by using the electronic certificates generated by the target object in different subsequent circulation batches as the compliance proof of the target object in different circulation links, the cumbersome operation of issuing paper certificates separately for multiple subjects involved in different circulation links of the same target object during the circulation process is avoided, and the human resource cost and social cost of repeated operations of the staff of the issuing institution are reduced. Secondly, by using the electronic certificates generated by the target object in subsequent circulation batches as the basis for tracing the target object in different circulation links, the problem that the paper certificate can be forged, resulting in the inability to trace or the high cost of tracing is effectively solved, which is conducive to quickly locating the problem link when a problem occurs in a certain circulation link, and improves the supervision efficiency of the target object in each circulation link of the circulation chain.

In one possible implementation, the management method of the electronic certificate for the target object in the embodiment of the present application may also include the following steps: performing risk verification on the electronic certificate corresponding to the target object in the current circulation batch according to preset rules, and the result of the risk verification is used to characterize the risk level of the target object.

Exemplarily, the preset rules can be set accordingly according to the type of target object, the type of downstream entity and at least one of the audit results. Among them, the audit result can be issued by the regulatory agency corresponding to the downstream entity. The regulatory agency can be responsible for the qualification inspection of the downstream entity and the inspection of the target object transferred to the downstream entity. For example, the qualification inspection can be whether the registration information of the downstream entity is complete, whether the safety and hygiene are qualified, etc. The inspection of the target object can be whether the origin information of the target object is complete, whether the epidemic prevention inspection is completed, etc. Based on the inspection results, the audit result can be generated. The audit result can be used as a component of the filing information.

The risk level can be high risk, medium risk or low risk. The results of risk verification can be displayed in text, code or color.

In a specific example, when the audit result is that both the qualification inspection and the target object inspection are unqualified, the risk level for the target object is high risk, and the result of risk verification can be displayed accordingly in red. When one or more items in the qualification inspection or the target object inspection are unqualified, the risk level for the target object is medium risk, and the result of risk verification can be displayed accordingly in yellow. When the audit result is that both the qualification inspection and the target object inspection are qualified, the risk level for the target object is low risk, and the result of risk verification can be displayed accordingly in green.

Through the above-mentioned implementation method, risk control of the target object is achieved for each circulation node in the circulation process of the target object, which is beneficial for the circulation entities, consumers and traceability systems that receive the target object in the circulation chain to quickly know the risk level of the target object, and can promptly verify and deal with medium-risk or high-risk target objects, thereby improving the safety of the target object in the market circulation process.

In one possible implementation, the management method of the electronic credential for the target object of the embodiment of the present application may also include the following steps: based on the electronic authentication data contained in the electronic credential, the electronic credential corresponding to the target object in the original batch and the electronic credential corresponding to the target object in each circulation batch are associated to obtain a traceability chain.

It is understandable that the electronic certificate corresponding to the target object in the original batch and the electronic certificate corresponding to the target object in each circulation batch both contain relevant information of the electronic certificate issued by the certificate issuance system for the target object, such as the number of the electronic certificate and the electronic image data. Based on this, the electronic certificates under different batches can be associated according to the relevant information of the same electronic certificate contained in the electronic certificates corresponding to the target object in different batches, thereby obtaining the traceability chain of the target object. Among them, the traceability chain can be used to indicate the flow direction of the target object at different circulation nodes, the upstream and downstream relationship between the subjects corresponding to different circulation nodes, the circulation time of each circulation node, and the circulation details of the target object at each circulation node (such as purchase time, purchase weight, transaction weight or transaction time, etc.).

Therefore, each batch of electronic vouchers can be used as a node in the circulation chain, and the circulation chain can be traced using any batch of electronic vouchers. In the circulation process of the target object, no matter where a problem is found, the source of the problem and the upstream and downstream entities involved can be queried according to the traceability chain, which is conducive to implementing the main responsibility, recalling or destroying the target objects of the same batch that have problems in the circulation process, and improving the security of market supervision.

In one possible implementation, the management method of the electronic certificate for the target object of the embodiment of the present application may also include the following steps: in response to a query request for the traceability chain corresponding to the target object initiated by the issuing system, a query service for the traceability chain is provided to the issuing system through a query interface.

In the embodiment of the present application, the query request is used to request to query the traceability chain of the target object stored in the traceability system. The query interface is used for the issuing system to access the database storing the traceability chain of the traceability system, so that the issuing system can access the traceability chain corresponding to the target object in the database.

As a result, the issuing system is able to query the traceability chain corresponding to the target object, allowing the issuing agency to monitor the target object's circulation in the market throughout the entire process and provide traceability evidence when a problem occurs in a certain circulation link, thereby quickly locating the circulation link where the problem occurs.

In one possible implementation, the electronic certificate includes a traceability code of the target object, which is used to generate at least one of the target object's commodity attribute information, the source entity's identity information, the target object's batch flow information, the target object's electronic certificate, the electronic certificate number information, and the query URL information of the issuing system when identified.

In the embodiment of the present application, the specific form of the traceability code can be a QR code, a barcode or other coding forms. When the traceability code is scanned and identified by a terminal device, it can generate at least one of the aforementioned multiple information.

In one example, the traceability code can be used to indicate the batch flow information of the target object, including the subject-related information and flow time information corresponding to the current batch.

Specifically, the traceability code may include a category code and a batch code. The category code is used to indicate the identity code information of the subject corresponding to the target object in the current batch, as well as the mapping relationship between the category and number of the food involved in the target object. The batch code is used to indicate the batch number of the electronic certificate corresponding to the target object in the current batch.

More specifically, the category code includes a 13-bit code representation, which represents the identity code information of the subject corresponding to the target object in the current batch (such as the source subject or the downstream subject corresponding to the source subject). For example, the 13-bit code can be expressed as N13N12N11...N1. Among them, N13N12 can be used as a prefix code. For non-natural persons, the prefix code ranges from 20 to 28, and for natural persons, the prefix code takes a value of 29. N11~N4 can be used as the identification information of the subject. For example, in the case where the subject is a non-natural person, the identification information can be the registration number or unified credit code of the subject. In the case where the subject is a natural person, N11~N4 can be the registration code of the natural person or the identification code agreed upon by the natural person and the circulation supervision system. N3N2 can be used as the code of the target object, which can distinguish 100 types of target objects. N1 can be used as a check code.

The batch code may include a 20-digit code, for example, it may be composed of a 14-digit time code and a 6-digit random code. The 14-digit time code may be expressed as YYYYMMDDHHMMSS, which corresponds to year (YYYY) month (MM) day (DD) hour (HH) minute (MM) second (SS). The 6-digit random code may be used to distinguish different flow batches of the target object at the same time. For example, for n downstream entities corresponding to different flow batches at the same time, a part of the n downstream entity pairs is transferred from the first institution to the first associated institution, and the other part is transferred from the first institution to the second associated institution, which can be distinguished by a 6-digit random code.

The embodiment of the present application also provides a method for managing electronic certificates for target objects, and the execution subject of the method may be a certificate issuance system. FIG. 4 is a flow chart of a method for managing electronic certificates for target objects in an embodiment of the present application. As shown in FIG. 4, the method for managing electronic certificates for target objects may include the following steps: Step S401: Based on the authentication request for the target object initiated by the source subject, the electronic authentication data of the target object is generated when the authentication is passed; in the embodiment of the present application, the target object may be a specific commodity that needs to be certified for compliance by the certificate issuance system. The certificate issuance system is an institution with relevant qualifications to inspect and certify specific commodities. The source subject may be a manufacturer, etc. For example, if the target object is a meat product, the source subject may specifically be a farm or a slaughterhouse. The electronic authentication data issued by the certificate issuance system may include structured information and an electronic certificate. The structured information specifically includes the commodity attribute information of the target object, the subject-related information corresponding to the target object, and the batch purchase information of the target object. Among them, the commodity attribute information may include the product name, quantity and unit, the name and address of the production unit, etc. of the target object. The subject-related information may include the subject's identification code, registration code, and qualification certificate. The electronic certificate can specifically be an electronic image of the compliance certification document corresponding to the target object.

Step S402: Encrypt the electronic authentication data using a message digest algorithm and send it to the traceability system.

For example, the issuing system can exchange data with the traceability system through an application program interface. Electronic certification data can be encrypted and transmitted using the MD5 message digest algorithm. The signature verification rule specifically performs double verification on the secret key provided by the traceability system and the submission timestamp.

In one possible implementation, the management method of electronic credentials for target objects may also include the following steps: receiving original batch reporting information corresponding to the target object and/or circulation batch reporting information corresponding to the target object under different circulation batches from the traceability system; the electronic authentication data includes structured information and electronic certificate corresponding to the target object; the electronic authentication data of the target object and the original batch reporting information and/or the circulation batch reporting information corresponding to the target object under different circulation batches are associated and stored.

Therefore, after receiving the original batch reporting information and the circulation batch reporting information, the issuing system can associate and store the electronic authentication data corresponding to the target object with the circulation status of the target object at each node in the subsequent market circulation links, thereby providing a supervision basis for the issuing system to the circulation process of the target object and providing a traceability basis when problems occur.

Corresponding to the application scenario and method of the method provided in the embodiment of the present application, the embodiment of the present application also provides a management device for the electronic certificate of the target object.

The first generating module 502 is used to generate the original batch filing information of the source subject based on the confirmation operation of the source subject on the target object;

The first association module 503 is used to associate the electronic authentication data with the original batch filing information to obtain the electronic certificate corresponding to the target object under the original batch;

The query service module 504 is used to respond to the query request initiated by the query subject for the electronic certificate and provide the query subject with a query service corresponding to the query authority of the query subject through the query interface.

In one possible implementation, the first sending module is also used to respond to the circulation operation on the target object, determine the downstream entity corresponding to the circulation operation and send a second confirmation request to the downstream entity; the first generating module is also used to generate the circulation batch reporting information of the downstream entity based on the downstream entity's confirmation operation on the target object; the first associating module is also used to associate the circulation batch reporting information with the electronic certificate to obtain the electronic certificate corresponding to the target object under the current circulation batch.

In one possible implementation, the management device for the electronic certificate of the target object also includes: a verification module, which is used to perform risk verification on the electronic certificate corresponding to the target object in the current circulation batch according to preset rules, and the result of the risk verification is used to characterize the risk level of the target object.

In one possible implementation, the data processing device also includes: a third association module, which is used to associate the electronic certificate corresponding to the target object in the original batch and the electronic certificates corresponding to the target object in different circulation batches based on the electronic authentication data contained in the electronic certificate to obtain a traceability chain.

In one possible implementation, the electronic certificate includes a traceability code of the target object, which is used to generate at least one of the target object's commodity attribute information, the source entity's identity information, the target object's batch flow information, the electronic certificate number information, and the query URL information of the issuing system when identified.
