The embodiment of the invention also provides a product tracing method based on NFT creation.
Referring to fig. 2, an embodiment of a product tracing method based on NFT creation in the present application is provided. In this embodiment, the product tracing method based on NFT creation includes:
s10, acquiring source certification information of the product;
the source identification information is specifically data that can provide identification for the source of the product to ensure that the product can be verified to have a legitimate, true, and legitimate source. The source identification information is prepared and provided by a relevant product outlet unit or a production unit of the product before the product is produced, and data is collected and sorted, and is associated with the product when the product is produced, so that the product can acquire the corresponding source identification information through the product after entering the market, determine the source of the product and verify the product.
Step S20, determining the certification information of the product according to the source certification information, and importing the certification information into a block chain;
the certification information is information that is used for storing in the blockchain after the source certification information is collated or processed. It should be noted that, when the source identification information includes a paper document, the paper document needs to be scanned to obtain a corresponding electronic document, and the corresponding electronic document is used as the identification information.
The block chain is a platform for storing the certification information, and data stored on the block chain has the characteristics of being not forged, not being tampered and being traceable based on the characteristic of block chain decentralization, so that the safety and the reliability of the certification information stored on the block chain are guaranteed. The blockchain may select a platform with a large number of NFT projects, such as a public chain or a federation chain.
The step of introducing the certification information into the block chain is to uplink data of the certification information in the block chain, pack the data in one block into a new block through a consensus mechanism of the block chain, and link the new block to the previous block to form data which cannot be tampered on the chain.
Step S30, creating an NFT of the product in the blockchain according to the certification information, so that the client verifies the product according to the source certification information in the NFT.
The NFT (Non-variant Token) is a virtual asset corresponding to a product, and provides guidance on how a user obtains the corresponding NFT while the user purchases the product, so that the user obtains the virtual asset corresponding to the product while obtaining a physical product. It should be noted that the evidence for creating the NFT may be any electronic data, and in this embodiment, the evidence information is used as the evidence for creating the NFT, so that the user can determine the source evidence information in the NFT to verify the product when obtaining the NFT of the product. Meanwhile, NFT also adds virtual collection value to the product.
The client is specifically a tool prepared for product verification, and a user can obtain the NFT corresponding to the product through the client after obtaining the product, and determine the source certification information in the NFT.
In specific implementation, a corresponding NFT is created on the block chain according to the certification information, after a user obtains a product, the user is guided to obtain the NFT corresponding to the product through a client, and the product is verified through the source certification information in the NFT.
The invention provides a product tracing method based on NFT creation, which comprises the steps of obtaining source certification information of a product, determining certification information of the product according to the source certification information, leading the certification information into a block chain, creating NFT of the product in the block chain according to the certification information, enabling a client to verify the product according to the source certification information in the NFT, and enabling the NFT created according to the source certification information to be free of counterfeiting or tampering except a design party, a production party and a related authorized unit, so that the source of the product can be accurately certified, and the accuracy of an anti-counterfeiting verification result of the product is improved.
Further, in this embodiment, the source identification information includes information of a product party, and the information of the product party includes verifiable digital information of a product unit or a product person;
the product output party is specifically the party responsible for the product output behavior of the product, and can be a company unit or a personal unit. The digital information may include a digital certificate, which is a digital certificate that can prove the identity information of the production unit or the producer, and can be signed electronically, for example, the digital certificate may be in the form of a digital U-shield or software. Digital certificates are typically issued by an institution with public trust, e.g., a bank or government. In addition, when the output unit or the output person can not provide the digital certificate, the digital information can also comprise bank account data with the same name as the output party, and the output party is proved through ways such as a small remittance record or a remark message serial number in the bank account data.
Further, depending on the size of the party, the party may choose to provide more information to prove the identity of the party, which may include a brand certificate and/or a business license of the party, and an identification of the party.
In addition, in other embodiments, the information of the output party can also comprise an original legal statement template with guarantee terms, and the output unit or the output person signs the statement, so that the reliability of the information of the output party is further improved. The signing mode of the declaration can be signing with a digital certificate of a product unit or a product person, or signing with a traditional paper file.
And/or the source certification information comprises design certification information, wherein the design certification information comprises design files, model files, design concept data and/or design process certification data of the product;
the design certification information is specifically data that can certify the design process of the product, and in this embodiment, the design certification information includes design files, model files, design concept data, and/or design process certification data. The design files include files involved in designing the product, such as cdr file of CorelDraw software or ai file of Adobe illustrator software. The design process proof material may be a screenshot file of the design process. In other embodiments, the design verification information may further include version alternation data of the product design to verify the version alternation process of the product from the initial version design to the later version design.
And/or the source certification information comprises product evaluation information, and the product evaluation information comprises a certificate and/or an evaluation report of the product.
The product evaluation information is specifically data that can be used to prove the value of a product when the product is a work with cultural or artistic value, such as an artwork. It should be noted that, some artworks cannot provide corresponding information of the production person and/or design certification information due to long production time, and the like, and the product evaluation information plays a role in compensating in such a situation. Further, the certification and/or evaluation report of the product is made by an organization with public trust. In other embodiments, the product assessment information may also include an exhibitions certification for the product at the related art exhibitions.
In addition, when the work can provide the information of the producer and/or the design certification information of the work, the corresponding information of the producer and/or the design certification information can still be used as the source certification information of the work, the information of the producer can be a digital certificate, an identity card and/or bank account data of an author, and the design certification information can be the creation material, creation manuscript and/or draft of the work.
In other embodiments, the source certification information may also include issuer information, providing information about the issuer of the product, to verify the regularity of the product distribution channel.
The product source, the design source and the value effectiveness of the product can be fully proved through the product party information, the design certification information and/or the product evaluation information, a reliable basis is provided for product verification, and the reliability of product verification is improved.
Further, in this embodiment, the step of determining certification information of the product according to the source certification information and importing the certification information into a block chain includes:
and when the data volume of the design certification information is less than or equal to a preset data volume, determining that the certification information comprises the design certification information and importing the design certification information into the block chain.
It should be noted that each operation on the blockchain has a corresponding gas cost, and in particular, the corresponding gas cost is generated according to the computing and storage resources consumed by the operations in the blockchain. In this embodiment, corresponding costs are also paid for importing the certification information into the blockchain and creating the NFT, and when the data amount of the certification information is greater than the preset data amount, the generated costs will affect the sales operation of the product.
In this embodiment, the source certification information includes manufacturer information, design certification information and/or product evaluation information, wherein the design files and model files in the design certification information have a larger data size than other contents of the source certification information, which may generate a gas cost higher than a predetermined requirement. Therefore, in the future, before the source certification information is imported into the blockchain, it is necessary to determine the data size of the design certification information, and when the data size of the design certification information is smaller than or equal to the preset data size, it is determined that the certification information of the imported blockchain includes the design certification information, so as to ensure that the operation of importing the data into the blockchain does not incur a cost higher than the preset requirement.
In addition, the preset data amount and the preset requirement are determined according to gas cost standards of the block chain in practical application and the type of the product.
By judging whether the data volume of the design certification information is less than or equal to the preset data volume or not, and when the data volume of the design certification information is determined to be less than or equal to the preset data volume, the certification information is determined to comprise the design certification information and the block chain is led in, the cost higher than the preset requirement is not generated by the operation related to the block chain, and the cost of product preparation at the early stage is reduced.
Further, based on the above embodiment, another embodiment of the product tracing method based on creating the NFT in the present application is provided. In this embodiment, referring to fig. 3, the source certification information includes design certification information, and the step of determining certification information of the product according to the source certification information and importing the certification information into the block chain includes:
step S21, when the data volume of the design certification information is larger than the preset data volume, adding a digital watermark into the design certification information, encrypting the design certification information, and importing the encrypted design certification information containing the digital watermark into the preset storage platform;
it should be noted that, when the data size of the design verification information is larger than the preset data size, the cost of introducing the design verification information into the block chain and creating the NFT will be higher than the preset requirement. In this embodiment, the design verification information is imported to the predetermined storage platform to reduce the required cost, and in other embodiments, the design verification information may be compressed and then imported to the block chain.
The preset storage platform is specifically a storage platform outside the blockchain, and further, because the storage platform outside the blockchain does not have the decentralized characteristic, the design certification information needs to be encrypted and protected, so that the security of the design certification information stored in the preset storage platform is improved.
Further, a digital watermark is added to the file of the design certification information to provide copyright protection. In addition, the data of the design certification information is subjected to encryption processing to improve the security of the data, such as hash encryption or symmetric encryption.
During specific implementation, the data volume of the design certification information in the source certification information is determined, whether the data volume is larger than the preset data volume or not is judged, when the data volume is larger than the preset data volume, the digital watermark is added into a file of the design certification information, the data of the design certification information is encrypted, and the encrypted design certification information added with the digital watermark is imported into a preset storage platform.
Step S22, determining that the certification information comprises a target address, adding a protection password in the target address and leading the target address into the block chain; and the target address is the address of the design certification information on the preset storage platform.
The target address is specifically an address used for positioning a storage position of the design certification information after the design certification information is imported into a preset storage platform. Further, the target address is an address protected by an SSL (Secure Sockets Layer) certificate, and meanwhile, the target address may be a URL or an IP address.
Furthermore, by adding a protection password to the target address to obtain the processed address, the design certification information on the preset storage platform can be prevented from being accessed by the target address after the non-NFT owner obtains the target address.
In this embodiment, the certification information of the import block chain includes the information of the product and the target address processed by the protection password, and the design certification information stored in the preset storage platform can be accessed through the target address. It should be noted that the information on which the NFT is created is the information of the producer and the destination address processed by the protection password.
During specific implementation, after the design certification information is imported into a preset storage platform, the storage address of the design certification information in the preset storage platform is determined, a protection password is added to the storage address, and the address processed by adding the protection password is imported into a block chain as the certification information.
By importing the design certification information into the preset storage platform and taking the address of the design certification information in the preset storage platform as the certification information for importing the block chain, the cost required for importing the certification information into the block chain and creating the NFT when the data volume of the design certification information is larger than the preset data volume can be reduced, and the cost for early preparation of products is reduced. Meanwhile, the design certification information and the target address are correspondingly encrypted, so that the data security when a preset storage platform is used instead of a block chain can be improved.
Further, based on the above embodiment, a further embodiment of the product tracing method based on creating the NFT is provided. In this embodiment, referring to fig. 4, after the step of creating the NFT of the product in the blockchain according to the certification information, the method further includes:
step S31, generating corresponding identification information according to the NFT; controlling a manufacturing module to manufacture an entity identifier corresponding to the identification information, wherein the entity identifier is a verification identifier of the product; the identification information comprises image information, a two-dimensional code and/or an electronic tag;
specifically, the entity identifier is an instantiated identifier created using the identification information as the content. Wherein, the content of the identification information is generated according to the corresponding NFT of the product, and the entity identification can be integrated with the product or separated from the product and attached to the mating element of the product. Furthermore, the form of integration of the identification information and the product can be that a solid label is manufactured by a labeling machine and is pasted on the product, the solid label can be a fragile label or a VOID label, and can also be laser-engraved on the product by a laser engraving machine or code-sprayed on the product by a code-spraying machine so as to form a solid identification on the product. Further, the identification information may be separated from the product in a form that is printed on a packing box, a certificate, a manual, a card and/or a hang tag of the product by a printer to manufacture the identification information on the kit to form the physical identification.
Furthermore, each NFT has a unique code as an identifier after being created, and the content of the identification information can be generated according to the code of the NFT after the NFT of the product is created. Specifically, the manner of generating the identification information includes: generating corresponding image information according to the NFT codes through a preset image coding rule; generating a corresponding two-dimensional code according to the NFT code by a two-dimensional code generator; the NFT code information is recorded in an IC Chip (Integrated Circuit Chip) having an RFID (Radio Frequency Identification) or NFC (Near Field Communication) function, thereby forming an electronic tag Chip. Correspondingly, the identification information corresponds to the image information, the two-dimensional code and/or the entity identification of the electronic tag.
In addition, through the scanning of the entity identification by the client, the verification website with the SSL certificate can be accessed, the NFT of the corresponding product is obtained, and the source certification information of the corresponding product can be determined through the NFT.
Step S32, when a scanning instruction of the identification information is received, acquiring native data of a terminal corresponding to the scanning instruction, wherein the native data comprises time information, position information and/or account information generated in the terminal; determining production information of the product according to the native data; importing the production information into the blockchain and updating the proof of origin information in the NFT.
Specifically, the terminal is a terminal equipped by an authorized manufacturer or monitor in a production workshop of the product, and when the product is produced, the terminal scans the identification information corresponding to the product to enter the production information corresponding to the product, so that the production information can also be used as the batch information corresponding to the product. The data content of the production information is provided by the terminal, when the terminal scans the identification information, the time information, the position information and/or the account information of the terminal are/is acquired, and the acquired information is used as the production information of the corresponding product.
In addition, the acquired production information is the original data of the terminal, the original data is generated and recorded by the terminal, and the original data is acquired from the terminal when the identification information is scanned without being modified or added manually. The time information is time data recorded by the terminal, the position information is data of the position of the terminal, and the account information is account data of an account used by the terminal.
It should be noted that the production information represents production batch information of the corresponding product, and is different from the product side information and the design certification information, and different batches of individuals in the same product have different production information. The production information of the lead-in block chain is associated with the information of the product outlet and the design certification information, so that after the client scans the identification information to obtain the NFT, the source certification information in the NFT can be determined to also include the production information.
In specific implementation, after a product is produced, scanning instructions of identification information are obtained by scanning entity identifications matched with the product, and after the scanning instructions are determined, native data of a terminal are obtained, wherein the native data comprise time information, position information and/or account information of the terminal, the obtained native data are used as production information of a corresponding product, the production information is imported into a block chain, and source identification information is updated.
Further, in the present embodiment, the product may include not only a product produced by industry but also a work having a cultural or artistic value produced or created by a person, and when the product is such a work, the corresponding production information may be entered by the producer or creator using a terminal, or by a relevant authorized entity when the work is transported to the entity.
By acquiring the production information of the product and importing the production information into the block chain to update the source certification information, the reliability of the source certification information can be further improved aiming at the production batch of the specific product verification during production, and the reliability of the product verification is improved.
Further, in this embodiment, before the step of obtaining the native data of the terminal corresponding to the scan instruction, the method further includes:
when the scanning instruction of the identification information is received, determining a current account of the terminal; when the current account meets a preset condition, executing the step of acquiring the native data of the terminal corresponding to the scanning instruction; the preset conditions include: the current account is an account of a lender of the product or an account of an entity authorized by the lender of the product.
Specifically, the current account is an account that the terminal logs in for use in order to implement the function of scanning the identification information. For safety, a terminal account for implementing the function of scanning identification information needs to satisfy a preset condition, where the preset condition is that a current account is an account of a seller of a product or an account of a unit authorized by the seller of the product. The preset condition represents that the account has enough authority, the account of a seller or a brand enterprise is an account manager, the function of scanning identification information can be realized, other accounts are authorized to realize the authority of the function, and the authorized unit is a production workshop or a delivery unit.
By setting the preset conditions for the account of the terminal, the scanning and the inputting of the production information of the account which does not meet the preset conditions can be prevented, the possibility that the production information is falsified and forged by others is reduced, and the reliability of product verification is improved.
Further, in this embodiment, after the step of importing the production information into the block chain, the method further includes:
acquiring state information of the product; when the state information is first information, associating the identification information with blank information so as to output the blank information when the identification information is scanned; when the status information is second information, associating the identification information with the NFT so that the identification information is scanned and the source attestation information in the NFT is output; the first information characterizes that the product has not arrived at an authorized unit, and the second information characterizes that the product has arrived at the authorized unit.
Specifically, in order to prevent the leakage of the product in the transportation process after the production is finished, so that other people can scan the identification information to obtain the NFT, before the product is transported to an authorization unit, the state information is the first information, and when the state information is the first information, blank information is output when the identification information is scanned; when the product is transported to an authorization unit, the state information is second information, the identification information is associated with the NFT corresponding to the product, and the identification information can output source certification information in the corresponding NFT and the NFT when being scanned.
Whether the product reaches the state of an authorization unit is distinguished through the state information so as to determine the content output when the identification information of the product is scanned when the product has different state information, thereby preventing the NFT and the source certification information of the product from being leaked to other people, improving the safety of the NFT and the source certification information and improving the reliability of product verification.
In addition, an embodiment of the present invention further provides a storage medium, where a product tracing program based on NFT creation is stored on the storage medium, and when executed by a processor, the product tracing program based on NFT creation implements relevant steps of any embodiment of the above product tracing method based on NFT creation.
