The issued value of the product may be obtained by hashing the calculated value of the product one or more times. The process of generating the issued value according to the code value is irreversible, so that the anti-counterfeiting capability is improved to a certain extent.
The code value of the package may contain a list of issued values and quantities of products within the package, a timestamp, a random value, and a digital signature of the above information by the packager.
The code value of the packet is attached to the packet, and can be printed by a label or written in a chip mode or the like. It should be noted that the process of attaching the code value to the bag is as irreversible as possible, for example, using a fragile sticker to print, using a chip that is not removable or rewritable, thereby increasing security.
S503: an issue value for the packet is generated from the code value of the packet, and the issue value for the packet is stored in the blockchain along with the issue values for all products within the packet.
The issued value of the packet is the information disclosed by the product in the circulation process, and can be obtained by hashing the code value to obtain a calculated value and hashing the calculated value one or more times.
The information stored to the blockchain may contain the digital signature of the packager in addition to the release value of the package and the release values of all products within the package.
S504: and in the process of packet circulation, storing the distribution value of the packet and the circulation information of each circulation node into the block chain.
In the process of packet circulation, for example, each link of warehousing, ex-warehouse and transportation, there are corresponding senders and receivers. The sender and the recipient may be the same entity or may be different entities.
When the package is circulated, a packager of the package initiates the circulation of the package for the first time, and a receiver of the package continues the circulation.
The flow information of each node may include: the distribution value of the sender, the receiver and the package, and the description information of time, place, environment and the like.
Because the flow is carried out in the form of the packet in the flow process, only the issuing value of the packet and the flow information of each flow node are required to be stored in the block chain, and the processing efficiency is improved.
S505: and when the package can not maintain the overall management and operation, performing at least one splitting treatment on the package to obtain the product to be traced.
A schematic of the packaging and unpacking of a product is shown in fig. 6. When the package is unable to maintain overall management and operation, it may be a portion of the product within the shipping or sales package, i.e., the package is broken up. The unpacker that splits the packet is the last receiver of the packet in the flow process.
To record this process of splitting a packet, corresponding information needs to be stored in the blockchain, for example: unpacking person, distribution value of the package, calculation value and quantity list of products in the package, and description information of time, place and the like. Since the distribution value and quantity lists of all products in the package are already stored and published in the blockchain, in order to avoid directly adopting this information, the calculation value and quantity lists of all products in the package are stored in the blockchain during the process of splitting the package.
Since the products in the packet may be lost or lost during the streaming process, when the packet is split, the number and quantity of all product calculation values in the packet may be less than or equal to the number and quantity of all product distribution values disclosed before the packet is streamed.
It should be noted that, after the bag is split, the products in the bag can continue to circulate, or can be packaged again to generate a new bag and then continue to circulate.
S506: and acquiring a code value attached to the product to be traced, and generating a calculated value and a release value of the product to be traced according to the code value.
After the bag is circulated and split for many times, the consumer purchases a product from the dealer, and the product is a product to be traced. Because the code value is attached to the product, the code value of the product to be traced can be acquired, and the calculated value and the issued value of the product to be traced are generated.
S507: and inquiring circulation information corresponding to the product to be traced in the block chain according to the code value, the calculated value and the issued value of the product to be traced so as to perform tracing verification on the product to be traced.
Because the release value or the calculated value of each link of the product in the circulation process is stored in the block chain, the circulation information of the product can be inquired in the block chain according to the code value, the calculated value and the release value of the product to be traced.
If the circulation information of the product to be traced is complete, the product tracing verification is successful.
After the to-be-traced product is successfully traced, the number of the to-be-traced products can be verified according to the number of the products from the same circulation source and the total number of the products from the same circulation source, which are stored in the block chain, of the to-be-traced products.
And if the sum of the number of the normal products and the number of the products from the same circulation source with the product to be traced is less than or equal to the total number of the products owned by the circulation source, the product to be traced is the normal product.
In an implementation scenario, if the information of the flow path of the product is missing, tracing the source of the product to be traced fails, and the product to be traced may be a counterfeit product.
In another implementation scenario, if the sum of the number of products from the same circulation source and the number of products to be traced is greater than the total number of products from the circulation source, there is a possibility that the products to be traced are counterfeit products.
Besides tracing and counterfeiting the product according to the code value, the calculated value and the issued value of the product, production enterprises can additionally provide inquiry and verification of the associated secret code hidden in the product, and more multimedia data information for verifying authenticity such as the production place, raw materials, processing process, packaging specification, appearance characteristics, packaging process and the like of the product. When the product is successfully verified, information related to the consumer, the distributor, the calculated value and quantity of the product, and the like, can be stored in the blockchain.
The embodiment of the application provides a source tracing anti-counterfeiting method, which comprises the steps of firstly obtaining code values and the number of products to be transferred, and packaging the products to generate packages. And generating a calculated value and a release value of the product and a code value of the package according to the code value of the product, and attaching the code value of the package to the package. And generating an issuing value of the packet according to the code value of the packet, storing the issuing value of the packet and issuing values of all products in the packet into the blockchain, and circulating the packet at the moment. And in the process of transferring the packet, storing the distribution value of the packet and the transfer information of each transfer node in the block chain. And when the package can not maintain the overall management and operation, the package is subjected to at least one splitting treatment to obtain a product. Aiming at a product to be traced in the hands of a final consumer, a code value attached to the product to be traced can be acquired, a calculation value and a release value of the product to be traced are generated, and circulation information of the product to be traced is inquired in a block chain according to the code value, the calculation value and the release value of the product to be traced. According to the traceability method, the product is circulated for many times from production, and the complete circulation information reaching the consumer is stored in the block chain, so that effective traceability verification can be performed on the circulation information of the product. By storing the release value obtained by calculation according to the code value attached to the product to be circulated in the block chain, the early leakage of the traceability anti-counterfeiting information of the product to be circulated is avoided, and the anti-counterfeiting traceability security is further improved.
