All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The embodiments and features of the embodiments of the present invention may be arbitrarily combined with each other without conflict. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.

In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.

Referring to fig. 1, an embodiment of the present invention provides a product tracing method, which may be applied to the product tracing system shown in fig. 2, and as shown in fig. 2, the product tracing system may include a CA (certificate issuing authority) for issuing a digital certificate to a product, a manufacturer terminal corresponding to a product manufacturer, a distributor terminal corresponding to a product distributor, a consumer terminal corresponding to a product consumer, and a cloud tracing platform. The flow of the method is described below.

Step 11: the method comprises the steps that a manufacturer terminal writes a manufacturer digital certificate and encrypted original production element information obtained by encrypting original production element information by using a private key of the manufacturer digital certificate into an NFC label, and sends the encrypted original production element information and NFC label identification information of the NFC label to a cloud traceability platform, so that the cloud traceability platform stores the encrypted original production element information and the NFC label identification information in a correlation manner; wherein, the NFC label sets up in the packing of product and unseals the department.

Each manufacturer may apply to the CA for a digital certificate belonging to that manufacturer, for example, a digital certificate applied to the CA by a manufacturer, referred to as a manufacturer digital certificate, which may be used to prove the legitimate identity of the manufacturer. After obtaining the manufacturer digital certificate, the manufacturer may collect the private key of the manufacturer digital certificate to cryptographically sign some specific information through the private key, and may otherwise disclose the public key of the manufacturer digital certificate to the public.

The original production element information of the product can be obtained by a product manufacturer in the process of producing the product, the original production element information of the product can comprise all information related to the production of the product, such as the production place, the production manufacturer, the production date, the production batch, the filling position, the filling machine model and the like of the product, and the condition related to the production of the product can be known through the production element information.

After obtaining the original production element information of the product, the product manufacturer can encrypt the original production element information of the product by using the private key of the manufacturer digital certificate to obtain encrypted original production element information (called encrypted original production element information), the original production element information of the product can be prevented from being tampered as much as possible by the private key encryption of the manufacturer digital certificate, so that the safety of the original production element information is ensured, the stealing and the stealing are prevented as much as possible, and the private key encryption can also ensure that the product is encrypted by a legal manufacturer of the product, because only the legal manufacturer of the product has the private key of the product. In the implementation, the original production factor information may be encrypted by the manufacturer digital certificate with a predetermined encryption algorithm, and the existing encryption algorithm may be used for the specific encryption algorithm, which is not described in detail herein.

Further, the product manufacturer may write a manufacturer digital certificate and the encrypted original production element information into the NFC tag together by using a manufacturer terminal (e.g., an NFC reader), where the manufacturer digital certificate includes a corresponding public key. Writing the manufacturer digital certificate into the NFC tag may facilitate subsequent processes such as scanning the NFC tag by a negotiable instrument through a terminal to directly obtain the negotiable manufacturer digital certificate, and further, may perform processing such as encryption on the negotiable information using the public key of the manufacturer digital certificate, that is, writing the manufacturer digital certificate into the NFC tag by a manufacturer is equivalent to disclosing the manufacturer digital certificate and the public key thereof to the negotiable instrument.

In the embodiment of the invention, the NFC label is arranged at the package unsealing position of the product, taking wine as an example, the NFC label can be arranged at the sealing position of the wine outer packaging box, when the wine outer packaging box is opened, the NFC label needs to be torn, the torn NFC label is abandoned and cannot be reused, so that the torn NFC label can be prevented from being applied to other packaging boxes to counterfeit the product, or the NFC label can be arranged at the joint of the bottle cap and the bottle mouth of a wine bottle, when a consumer uses the wine, the wine cap can be opened to pour out the wine by tearing the NFC label first, and therefore, the torn NFC label can be prevented from being applied to other wine bottles to counterfeit. That is, the NFC tag may be regarded as disposable, and the corresponding NFC tag is disabled after the product is used, so that counterfeiting by the NFC tag on the used product may be avoided as much as possible. In addition, the NFC tag may be fixedly arranged on a package unsealing position of the product by a manufacturer in a printing, pasting, or embedding manner before the product leaves a factory, so that it is ensured that the NFC tag is already attached to the product before the product flows into the market.

In a specific implementation process, a manufacturer may use a dedicated reader/writer to write information that needs to be stored in an NFC tag into the NFC tag, or may also use a terminal device with an NFC function to write related information into the NFC tag, for example, the manufacturer may configure a dedicated terminal device (e.g., a mobile phone) with an NFC function to write information into the NFC tag or read information from the NFC tag.

The NFC technology is a non-contact radio frequency identification and interconnection technology which is separated from wireless equipment, and has the characteristics of non-contact, unique identification, read-write and the like, a wireless communication protocol of the NFC technology is developed, and the RFID tag is completely compatible with the NFC technology.

Meanwhile, the product manufacturer can upload the encrypted original production element information and the NFC label identification information (such as the ID of the NFC label) to the cloud traceability platform, and the cloud traceability platform can store the encrypted original production element information and the NFC label identification information in an associated manner after receiving the information. The original production element information can be ensured to be not tampered and stolen by lawbreakers in the transmission and storage process as much as possible by the mode that the original production element information is encrypted by the manufacturer digital certificate and then transmitted and stored, so that the safety of the production information is ensured as much as possible, and the possibility of counterfeiting products is radically reduced

And the encrypted original production element information and the NFC label identification information are stored in an associated mode, so that the corresponding encrypted original production element information can be found only through the NFC label identification information in the subsequent use process. Because the information stored by the cloud traceability platform is more, in order to ensure the accuracy of the corresponding information of each product, the encrypted original production element information of the product can be stored in an associated manner by using the NFC tag identification information. Moreover, as long as all subsequently received related information of the product can be stored in the manner of storing the related information of the NFC tag identification information, the subsequent related information can be conveniently and directly searched through the NFC tag identification information, that is, the NFC tag identification information can be regarded as a search index of the related information, so that the accuracy of information search and quick query can be ensured.

In addition, the cloud traceability platform can directly find the manufacturer digital certificate corresponding to the NFC tag identification information from the cloud, and the manufacturer digital certificate can be uploaded to the cloud traceability platform after being applied to and obtained by the manufacturer from the CA, or can be directly obtained by the cloud traceability platform through querying from a CA management authority, and the like. Further, when the original production element information needs to be called, the cloud traceability platform can decrypt the stored encrypted original production element information by using a private key of the manufacturer digital certificate to obtain the original production element information, and then the subsequent operation is completed.

Step 12: the method comprises the steps that a carrier terminal reads an NFC label to obtain a manufacturer digital certificate and NFC label identification information, encrypted original circulation element information obtained by encrypting original circulation element information by using a public key of the manufacturer digital certificate is written into the NFC label, and the encrypted original circulation element information and the NFC label identification information are sent to a cloud traceability platform, so that the cloud traceability platform stores the encrypted original circulation element information and the NFC label identification information in a correlation mode.

After leaving the factory, the product may arrive at the consumer after a certain circulation, when the product circulates to the distributor, the distributor may obtain circulation factor information of the product circulated to the distributor, the distributor may automatically acquire the circulation factor information of the product using a terminal device (for example, referred to as a distributor terminal), for example, the current date and the location may be detected by a mobile phone, or the circulation factor information may be manually entered by the distributor, or the like. The original circulation element information of the product may include a collection date of the circulation information, a collector of the circulation information, a location where the circulation information is collected, a location where the product is stored, environmental information where the product is stored, a current level of a distributor, and the like, that is, the circulation element information of the product is information related to a circulation situation of the product. For convenience of description, in the embodiment of the present invention, circulation element information acquired by a legal circulation dealer is referred to as original circulation element information.

Because one-stage or multi-stage circulation is possible in the actual circulation, each stage of circulation trader can acquire the information of circulation elements from the circulation of the product to the current circulation by adopting the mode, and the complete circulation condition of the product from the factory to the final arrival at the consumer can be acquired by the accumulated record of each stage of circulation condition of all circulation traders.

In addition, when the product is circulated to a certain current place, the current circulation merchant can obtain the manufacturer digital certificate and the NFC label identification information by reading the NFC label at the product package unsealing position, then the obtained original circulation element information is encrypted by using the public key of the manufacturer digital certificate to obtain the encrypted original circulation element information, the encrypted original circulation element information is further written into the NFC label, and the encrypted original circulation element information and the NFC label identification information are uploaded to the cloud traceability platform together, and the cloud traceability platform can perform associated storage on the encrypted original circulation element information and the NFC label identification information uploaded by the circulation merchant terminal after receiving the two information. The original circulation element information is encrypted by the manufacturer digital certificate and then transmitted and stored, so that the original circulation element information can be ensured to be prevented from being tampered and stolen by lawbreakers in the transmission and storage processes as much as possible, the safety of the circulation information is ensured as much as possible, and the possibility of counterfeiting products is radically reduced.

It can be understood that if there are multiple levels of circulation merchants, each level of circulation merchants can upload original circulation element information of commodities circulating to the local place to the cloud traceability platform in an associated manner with the NFC tag identification information after encryption processing, and the cloud traceability platform can obtain the complete circulation path condition of the product in the whole circulation process through accumulated uploading of each level of circulation merchants.

Step 13: the consumer terminal reads the NFC label to obtain NFC label identification information, encrypted production element information and encrypted circulation element information, and sends the encrypted production element information, the encrypted circulation element information and the NFC label identification information to the cloud traceability platform.

The product leaves the factory after, the product that is provided with aforementioned NFC label can circulate in the market, when circulating to consumer department, the consumer can perhaps trace back the source and verify whether this product is genuine, the consumer can use the NFC label that consumer's terminal (for example have the cell-phone of NFC function) set up on the direct scanning product of consumer terminal this moment in order to read NFC label identification information, encrypt production essential element information and encrypt circulation essential element information, and pass through the cell-phone and upload these information associations that the scanning obtained to the cloud platform of tracing back, and then with tracing back the source and distinguish the true and false of product through the cloud platform of tracing back.

Because the product may be counterfeit, if the product is counterfeit, the encrypted information stored in the NFC tag may not be the encrypted original production element information written by the legal manufacturer at the time of product shipment and the encrypted original circulation element information written by the legal distributor during circulation, but the fake manufacturer imitates the encrypted information written by the legal producer and the legal distributor, so that the consumer scans and reads the natural, namely not real, encrypted original production element information and encrypted original circulation element information through the consumer terminal, therefore, in the embodiment of the invention, for the purpose of distinguishing, the information scanned and read by the consumer terminal and the information written by the legal producer are distinguished by the 'encrypted production element information' and the 'encrypted original production element information', and distinguishing information scanned and read by the consumer terminal and written by a legal distributor by using the 'encrypted circulation element information' and the 'encrypted original circulation element information'.

Step 14: the cloud traceability platform decrypts the encrypted production element information and the encrypted original production element information respectively by using a public key of the manufacturer digital certificate to obtain the production element information and the original production element information, decrypts the encrypted circulation element information and the encrypted original circulation element information respectively by using a private key of the manufacturer digital certificate to obtain circulation element information and original circulation element information, and matches and compares the production element information and the circulation element information with the corresponding original production element information and the original circulation element information respectively to determine the authenticity of the product and the production circulation condition according to a matching result.

After receiving the NFC tag identification information, the encrypted production element information, and the encrypted circulation element information uploaded by the consumer, the cloud traceability platform may first find a corresponding manufacturer digital certificate using the NFC tag identification information, then decrypt the encrypted production element information uploaded by the consumer terminal and the previously stored encrypted original production element information respectively using a public key of the manufacturer digital certificate to obtain the production element information and the original production element information, and decrypt the encrypted circulation element information uploaded by the consumer terminal and the previously stored encrypted original circulation element information respectively using a private key of the manufacturer digital certificate to obtain the circulation element information and the original circulation element information, that is, decrypt the encrypted production element information with the public key, and decrypt the encrypted circulation element information with the private key.

Further, matching and comparing the production element information obtained by decryption with the original production element information, matching and comparing the circulation element information obtained by decryption with the original circulation element information, and determining the authenticity and the production circulation condition of the product according to the final matching result.

When comparing two production factor information and two circulation factor information, respectively, there may be different comparison results, and some possible cases will be described below for the convenience of those skilled in the art to understand.

If the product is genuine, the cloud traceability platform can successfully decrypt the encrypted production element information uploaded by the consumer terminal by using the public key of the manufacturer digital certificate, and the obtained decrypted production element information is consistent with the original production element information.

If the product is a counterfeit product, since the counterfeiter does not know the encryption mode agreed between the cloud traceability platform and the cloud traceability platform, the cloud traceability platform cannot decrypt the encrypted production element information uploaded by the consumer terminal through the public key of the manufacturer digital certificate, and the finally obtained decryption result may be messy codes or cannot be decrypted at all, so that the finally obtained decrypted production element information is not matched with the original production element information naturally.

If the product is a counterfeit product, a counterfeiter may also obtain the private key of the manufacturer digital certificate in some way and encrypt the production information by the private key of the manufacturer digital certificate, but since the product is counterfeit, the obtained counterfeit production element information is definitely different from the original production element information of a legal manufacturer, so that even after the encrypted production element information uploaded by the consumer terminal is successfully decrypted by the private key of the manufacturer digital certificate, the obtained decrypted production element information is not matched with the original production element information.

As described above, if the product is genuine, the decrypted production factor information is the same as the original production factor information, and naturally matches with the original production factor information, and the matching result at this time indicates that the product is genuine. If the product is a counterfeit product, the decrypted production element information obtains a messy code due to a decoding error, or the decrypted production element information is the original encrypted production element information due to a decoding failure, or even if the decrypted production element information obtained by the decryption is different from the original production element information, the decrypted production element information and the original production element information are not matched in general, and the authentication result shows that the product is an unqualified product.

The matching description is only performed on the production factor information, and the circulation factor information is also understood in the same way, that is, if the matching result is consistent, the circulation information is true, which can truly reflect the circulation condition of the product, such as the name of the circulation provider and the specific circulation path, and if the matching result is inconsistent, the circulation is problematic.

No matter the identification result is, the cloud traceability platform can feed the identification result back to the consumer terminal, so that the consumer can directly know the verification traceability result and the production circulation condition of the authenticity of the product by checking the mobile phone. If the product is determined to be genuine, the consumer can be relieved to use the product, and if the product is determined to be non-genuine, the product can be reported to the related alarm platform directly through the mobile phone, for example, a report message is sent to the 12315 platform directly. For example, if it is determined that the circulation element information is not authentic, it may be determined that the product is obtained through an unauthorized channel or even an illegal channel, and the product may not be purchased enough and may be reported to the relevant departments at the same time. In the embodiment of the invention, the mode of encrypting and decrypting the production and circulation element information of the product through the manufacturer digital certificate not only can be convenient for consumers to know the real circulation condition of the product so as to ensure the safety of the production and circulation element information of the product, but also can add certain interest to the users when the users consume the product and increase the probability of purchasing the product.

And, if the product is genuine, the cloud traceability platform can also send the decrypted production element information (namely, original production element information) and the decrypted circulation element information (namely, original circulation element information) to the consumer terminal, so that the consumer can check the original production element information and the original circulation element information of the product, and the production condition and circulation of the product are roughly known, so that the consumer can visually know the whole circulation process of the product, and can also know the complete circulation element information of the product at each stage of circulation merchant, and the circulation process of the product can be made transparent by the way, so that the consumer can conveniently supervise to a certain extent, and the brand recognition degree of the product can be improved. Meanwhile, the product can be promoted in consumers, and the brand image of the product is erected in the heart of the consumers.

If the product is a non-genuine product, the cloud traceability platform can also respectively identify the decrypted production element information and the original production element information and then send the identification to the consumer terminal, for example, the original production element information is marked by characters such as green or 'genuine product production information', the decrypted production element information (i.e. counterfeit production information) is marked by characters such as red or 'counterfeit production information', similarly, the true and false circulation element information can also be processed identically, and under the condition of multi-stage distributors, the cloud traceability platform can also correspondingly send the counterfeit circulation information and the true circulation information to the consumer, so that the consumer can directly determine the circulation link with problems from the numerous distributors, and the consumer can conveniently and intuitively know the difference between the production circulation conditions of the genuine product and the counterfeit product, increase follow-up prevention consciousness to similar counterfeit product, the user of being convenient for simultaneously knows the counterfeit and real circulation key element information, plays the prerequisite of certain suggestion effect to the user under, can also warn the user so that the user reports relevant department.

In a possible implementation, after the consumer terminal receives the true and false and the feedback result of the circulation condition fed back by the cloud tracing platform, the consumer terminal can display the product according to the sequence of the circulation time in a hierarchical manner so as to visually display the circulation path of the product, for example, the product is displayed in a tree-shaped manner, for example, the product is displayed in a text manner according to the time sequence, or each circulation position can be marked on a map in a time sequence or in different colors, so that a user can visually know the circulation path of the product, the user can know the complete circulation path of the product more visually, the interest of consumption is further promoted, and meanwhile, the consumer can perform preliminary true and false judgment on the circulation condition of the product.

According to the introduction, the production element information and the circulation element information of the product are verified mainly through the cloud traceability platform, in practice, the cloud traceability platform can be a server with data processing, storage and management functions, please refer to the architecture diagram of the cloud traceability system shown in fig. 3, and the cloud traceability platform in the embodiment of the invention can include a digital certificate management module, an NFC tag management module, a production element information management module, a circulation element information management module and a traceability verification module. Wherein, the digital certificate management module is used for storing and managing a manufacturer digital certificate, the NFC label management module is used for storing and managing NFC label identification information of an NFC label, the production element information management module is used for storing and managing production element information of a product, the production element information of the product can comprise original production element information, encrypted original production element information, decrypted encrypted production element information and other information related to the production and production of the product, the circulation element information management module is used for storing and managing circulation element information of the product, the circulation element information of the product can comprise original circulation element information, and the tracing verification module is used for performing product authenticity tracing verification and feeding back an obtained verification result to the consumer terminal.

In one possible embodiment, after obtaining the original production element information, the manufacturer may also write the original production element information directly into the NFC tag through the manufacturer terminal. And after the original circulation element information is obtained by the circulation provider, the original circulation element information can be directly written into the NFC label through the circulation provider terminal.

In another possible implementation manner, after obtaining the original production element information, the manufacturer may further extract key information from the original production element information to obtain summary production element information, and then directly write the summary production element information into the NFC tag through the manufacturer terminal. And after obtaining the original circulation element information, the circulation provider can extract key information of the original circulation element information to obtain summary circulation element information, and then the summary circulation element information is directly written into the NFC label through the circulation provider terminal. For example, the original production factor information is "place of origin: manufacturer located in the city wuhou MM street NN plant; the production date is as follows: 15 points on 12, 6 and 6 days in 2017 for 33 points; filling information: the general production element information obtained after the general extraction of the K filling opening of the YY section filling pipe of the XX type filling machine is' origin: manufacturer to capital plant; the production date is as follows: 12 months and 6 days 2017; filling information: XX model filler ", it can be seen that the summary production element information after summary extraction includes key information in the original production element information, but the amount of information is relatively reduced.

Further, when the product is distributed to the consumer, the consumer can scan the NFC tag on the product through the mobile phone to directly obtain the original production element information and the original distribution element information, or can directly obtain the summary production element information and the summary distribution element information, so that the user can conveniently and quickly know the production condition of the product, and the authenticity of the product can be preliminarily and quickly determined through the information, for example, for a certain brand of product, a production factory is not set up at all at the success, and if the original production element information or the summary production element information obtained through scanning indicates that the production place is success, the product can be obviously determined to be a counterfeit product. If the authenticity of the product is further determined, the verification feedback method with the cloud tracing platform introduced in the foregoing can be adopted to further verify the authenticity.

Moreover, because the NFC function in the terminal equipment is used for scanning the NFC label to obtain the information stored in the NFC label without equipment networking, the production element information and the circulation element information of the product can be obtained by directly using the NFC scanning function when the consumer terminal cannot be networked or does not need networking (flow is saved) by directly writing the unencrypted production element information and the unencrypted circulation element information into the NFC label, so that the hardware and environment requirements for checking the production element information and the circulation element information can be reduced to a certain extent, the popularization is facilitated, and meanwhile, the consumer can roughly judge the authenticity and circulation condition of the product in advance.

In a specific implementation process, the multiple types of information written in the NFC tag can be stored in a partitioned manner, that is, the information in the NFC tag can be stored in a partitioned manner, and unified storage and management of different types of information can be realized by the way of partitioned storage, so that the efficiency of information management is improved. For example, the storage area of the NFC tag may be divided into three independent storage areas, the manufacturer digital certificate may be stored in a first storage area, unencrypted information (e.g., original production element information and original circulation element information) may be stored in a second storage area, and encrypted information (e.g., encrypted original production element information and encrypted original circulation element information) may be stored in a third storage area, or the first storage area may be used to store the manufacturer digital certificate, the second storage area may be used to store production-related information (e.g., original production element information and encrypted original production element information), and the third storage area may be used to store circulation-related information (e.g., original circulation element information and encrypted original circulation element information), or other division manners may be used, and will not be illustrated, it should be understood that the foregoing two possible storage area division manners are merely illustrative and are not to be construed as limiting the embodiments of the present invention.

In the embodiment of the invention, most of the current terminal equipment has the NFC function, the NFC function can be conveniently used through the terminal equipment without additionally installing application software, and meanwhile, the NFC label does not need expensive reading and writing equipment, so that the production and use cost can be greatly reduced by carrying out the product authenticity verification and the product traceability through the NFC label used by a low threshold, thereby reducing the environment and equipment requirements of the consumer for verifying the product authenticity and the product traceability and being beneficial to popularization and use. Moreover, after the cloud traceability platform decrypts the original production element information and the original circulation element information of the product through the manufacturer digital certificate, then the decrypted information is respectively compared with the original information uploaded by the manufacturer and the negotiable merchant to verify the authenticity and the source tracing of the product, the possibility that the original production information and the original circulation information of the product are falsified and stolen can be reduced, so that the authenticity verification of the product and the accuracy of production circulation tracing can be ensured, the consumer can conveniently and effectively distinguish the product, meanwhile, the original production element information and the original circulation element information are encrypted and protected by a manufacturer digital certificate, the method can prevent other counterfeiters from stealing the original information of the product and effectively avoid being counterfeited, radically reduces the possibility of the product being counterfeited so as to further ensure the safety of the product, and further can protect the interests and the reputation of legal manufacturers to a certain extent.
