The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It is also to be understood that the terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the specification of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As shown in the method flowchart of fig. 1, a flowchart of a specific embodiment of a wine information tracing method based on a block chain provided by the present invention includes the following steps:
s1, establishing a alliance chain comprising a plurality of wine factory nodes and supervision agency nodes by using a block chain bottom platform;
step S2, acquiring first anti-counterfeiting information corresponding to the anti-counterfeiting code of the wine bottle body by using a wine factory node, and uploading the first anti-counterfeiting information to a block chain for storage after the first anti-counterfeiting information is signed by a wine factory private key;
step S3, second anti-counterfeiting information obtained through calculation according to anti-counterfeiting codes of the wine bottle bodies obtained by the agent and the retailer is obtained, and the second anti-counterfeiting information is uploaded to a block chain for storage after being signed by the agent or the retailer through a private key;
step S4, third anti-counterfeiting information obtained through calculation according to anti-counterfeiting codes of wine bottle bodies purchased by consumers is obtained, whether corresponding first anti-counterfeiting information and second anti-counterfeiting information exist in a block chain is inquired according to the third anti-counterfeiting information, original information of wine in private databases of wine manufacturers, agents and retailers is inquired according to the third anti-counterfeiting information, fourth anti-counterfeiting information is calculated according to the original information, whether the fourth anti-counterfeiting information is consistent with the first anti-counterfeiting information and the second anti-counterfeiting information is judged, and a judgment result is fed back to the consumers.
Specifically, the step S1 is to combine multiple winery manufacturers and third-party monitoring agencies, each agency establishes one or more block chain nodes, and forms a block chain network together, and maintains data in the block chain through a P2P protocol, so as to identify the data together, thereby ensuring that the data of each node is consistent, and the data is indelible and cannot be tampered.
Nodes for information uploading and inquiring can be respectively set for consumers, agents and retailers, so that the consumers or the agents can conveniently trace the source of the wine and inquire the authenticity of the wine.
In a preferred embodiment, the step S2 further includes calculating the bottle body anti-counterfeit code by a hash operation to obtain a hash value of the bottle body anti-counterfeit code.
The hash operation is to convert an input (also called pre-mapped pre-image) of an arbitrary length into an output of a fixed length by a hash algorithm, and the output is a hash value. This transformation is a kind of compression mapping, i.e. the space of hash values is usually much smaller than the space of inputs, different inputs may hash to the same output, so it is not possible to determine a unique input value from a hash value. In short, it is a function of compressing a message of an arbitrary length to a message digest of a certain fixed length.
The first forgery prevention information in the present embodiment is information including a hash value obtained by hash operation (it is also understood that the second forgery prevention information, the third forgery prevention information, and the fourth forgery prevention information related to steps S3 and S4 are all of this type).
In a preferred embodiment, the step S2 further includes storing the anti-counterfeit code of the wine bottle and the original information of the wine in a private database of the wine manufacturer.
Specifically, the original information is stored for the purpose of facilitating retrieval by a user during tracing, wherein the uplink data format may adopt but is not limited to { anti-counterfeiting code hash, information hash } (the hash is the hash value calculated above).
In a preferred embodiment, the step S3 further includes calculating the anti-counterfeit code of the bottle body obtained by the agent and the retailer by using a hash operation to obtain a hash value of the anti-counterfeit code of the bottle body obtained by the agent and the retailer by the hash operation.
Similarly, the anti-counterfeiting code is not directly uploaded in the data processing in step S3, so as to protect the privacy information of the drinks manufacturer, prevent the anti-counterfeiting code from being leaked, and prevent illegal persons from performing illegal behaviors such as counterfeiting.
In a preferred embodiment, the step S3 further includes storing the anti-counterfeit code and the original information of the wine bottle body obtained by the agent and the retailer in private databases of the agent and the retailer.
When the consumer goes back to the source to inquire the authenticity, the information about the wine taken by the agent or the retailer, i.e. the original information in the embodiment, also needs to be displayed.
As an alternative embodiment, as shown in fig. 2, the flow of the anti-counterfeiting processing steps performed by the nodes such as the white spirit enterprises and the dealers by using the traceability method of the present invention is shown as follows:
a white spirit manufacturer firstly generates an anti-counterfeiting code, stores the anti-counterfeiting code in a spirit bottle body and calculates the hash value of the anti-counterfeiting code. And secondly, calculating the hash value of the wine production information. And then the two generated data are uploaded to a block chain system for storage after the private key signature of the wine enterprise is completed. The data format on the chain is { anti-counterfeiting code hash, information hash }, and the anti-counterfeiting code and the original information of the wine are stored in the internal system of the wine enterprise.
After the dealers and the retailers take the wine, the anti-counterfeiting code information of the wine is read. And similarly, calculating the hash value of the anti-counterfeiting code, and then calculating the hash value of the anti-counterfeiting code according to the self information. After being signed by the private key of the own organization, the signature is uploaded to a block chain system for storage. The on-chain data format is similar to the production mechanism. Similarly, agents and retailers also store raw information in their own internal systems.
In a preferred embodiment, the step S4 further includes calculating the anti-counterfeit code of the bottle body purchased by the consumer by using a hash operation to obtain a hash value of the anti-counterfeit code of the bottle body purchased by the consumer, similarly to the first anti-counterfeit information and the second anti-counterfeit information.
Preferably, the step S4 further includes writing the verification result into the private database of the blockchain and the corresponding node if the fourth anti-counterfeit information is consistent with the first anti-counterfeit information and the second anti-counterfeit information, and querying the private database of the wine manufacturer, the agency or the retailer for the original information about the anti-counterfeit code of the wine bottle body and feeding the information back to the consumer.
Specifically, the step of the consumer performing query tracing is as shown in fig. 3, the consumer may input the anti-counterfeiting code according to the APP, then the APP performs the query of the hash value according to the processing step of step S4, and finally the result of the judgment (for example, original information is not queried or original information about wine is queried about wine manufacturers and agents) is displayed to the consumer, and the consumer may judge the authenticity according to the result of the query.
As a preferred embodiment, the present invention processes data by using a private key signature, specifically, the private key signature is intended to realize the identity authentication of a user, in the digital signature, a public key is an identity flag, and when the private key signature is used, if a receiving party or a verifying party verifies and passes through the public key, it can be determined that a signer is the person who owns the private key, because the private key is known only by the signer. By the method, whether the data are uploaded by wine manufacturers or dealers and the like can be effectively verified, and authenticity of the data is guaranteed.
As an optional implementation manner, the above steps S1-S2-S3-S4 further need to use a data uploading step, as shown in fig. 4, including five links of production, logistics, distribution, retail and consumer, and in combination with the steps S1-S4 of the tracing method of the present invention, the relevant information of each link is calculated by a hash operation method and then uploaded to the blockchain system, so that the tracing effect is better achieved, and the following defects in the conventional technology are also avoided:
the identification of the anti-counterfeiting chip requires specific equipment identification, and the popularization rate is not high
The anti-counterfeiting data is stored in a centralized manner and is easy to be attacked by hackers or tampered with by internal works
The source tracing operation of the anti-counterfeiting information can not be carried out
Chip procurement development and verification require costs.
