The first embodiment is as follows:
a block chaining-based certified traceability method, see fig. 1, includes the following steps:
s1: collecting product production information including basic information, production link locations and time;
specifically, step S1 collects all data in the production process of the product. For example, the product name, production date, inspector, inspection date, ex-warehouse information, warehousing information, logistics information, and location and time of each production link.
S2: transmitting the product production information to a data collector;
specifically, production information is generally collected by a traceability enterprise and transmitted to a data collector.
S3: receiving processing data uploaded by a data enterprise, analyzing the processing data, dividing the processing data into traceability data and commodity data, storing the commodity data into a solr, and storing the traceability data into a block chain through a web3j component to complete information chaining;
specifically, the processing data is typically an xml format file, and step S3 stores some commodity data that is not desired to be disclosed to the consuming user into the solr. solr refers to an independent enterprise-level search application server. And storing the traceability data which can be disclosed to the consuming user into the block chain for the consuming user to inquire. The web3j component is a lightweight, Reactive, type-safe Java library.
S4: receiving a query instruction which is uploaded by equipment and contains a commodity, calling a block which stores traceability data in the commodity on a block chain according to the query instruction, and checking traceability information stored in the block.
In particular, the commodity data is generally confidential information, such as user information and enterprise information, which is not desired to be disclosed to the outside for the consumer to inquire. The consuming user can only query the tracing data stored in the blockchain. When a consumer wants to query the traceability data of a certain commodity, the consumer scans the identification, such as a two-dimensional code, on the commodity through the traceability APP on the device, sends out a query instruction, calls a corresponding block on the block chain according to information such as the name or code of the commodity in the query instruction, and sends the traceability information in the block to the device of the consumer for display. Therefore, the efficiency can be improved, and the important information can not be changed.
According to the method, the data are classified into the traceability data and the commodity data for classified storage, a consumer can inquire the traceability information stored on the block chain, and the safety and the operation speed of the data are improved.
Preferably, the product production information is collected by identification bar code, identification two-dimensional code, RFID radio frequency reading and/or ocr identification software.
Specifically, the traceability enterprise can acquire product production information by various methods such as bar code identification, two-dimensional code identification, RFID reading, ocr identification and the like. ocr is a common type of character recognition software.
Preferably, the storing the source tracing data into the block chain through the web3j component specifically includes:
the traceback data is converted into a binary string, which is stored into a blockchain by the web3j component.
Specifically, after the method finishes data chaining, data is packaged and stored on the block chain, and anyone can not delete or modify the data, so that the authenticity of the traceability information is ensured.
Preferably, the block chain is a federation chain;
specifically, the method adopts a alliance chain instead of an unlimited public chain system, and can protect user privacy and enterprise confidentiality to the maximum extent on the basis of ensuring decentralized operation.
Before the collecting the product production information, the method further comprises the following steps:
and when receiving a joining application initiated by the equipment, auditing the joining application, and when the auditing is passed, defining the equipment initiating the joining application as the node of the alliance chain.
Specifically, the block chain in the method is a federation chain, and when a device wants to participate in the certified tracing source block chain, the device needs to apply in advance, and the device can become a node after passing the certification. A node comprises a personal computer, server, etc. that provides computing power. According to the method, identity control is introduced into the block chain, the internal trust of the network is enhanced, verification operation is simplified, and system efficiency is improved.
Preferably, after completing the uplink of the information, the method further comprises:
in the block chain block generating process, when two nodes are detected to calculate the titles issued by the block chain at the same time, the node with longer working time is obtained, and the preset block reward is distributed to the node.
Specifically, a currency age mechanism is added in the method, and when two nodes calculate topics issued by a block chain at the same time in the block chain generating process, the method can automatically judge which node has longer working time and distribute block rewards to the nodes with longer working time. The automatic judgment allocates the block reward to the nodes with longer working time, thereby effectively preventing the concurrency defect of the block chain network.
Preferably, each commodity is provided with a unique traceability code, a traceability certificate and a password, the traceability code is used for a consumer to inquire traceability information, the password is used for getting the traceability certificate of the commodity, and the password is arranged inside a package of the commodity and corresponds to the traceability code one to one.
Specifically, since the password is provided inside the package of the commodity, the password can be obtained only by destroying the package of the commodity. When a consumer wants to obtain the traceability permit, the consumer firstly destroys the package of the commodity, and after obtaining the password, inputs the password in the traceability APP to search the corresponding traceability code, so as to obtain the only traceability permit.
Preferably, the traceability certificate of each item can only be retrieved once.
Specifically, since the traceability certificate of each commodity can only be received once, when the commodity is consumed for the first time, the consumer can receive the traceability certificate through the traceability code, so that if an illegal user forges a counterfeit commodity by using a package of the commodity, the subsequent consumer cannot receive the traceability certificate through the traceability code, and the commodity can be described as being consumed or forged at this time. The retrieved traceability pass-throughs can be stored directly in the user's wallet of the consuming user.
Preferably, after the reviewing the tracing information stored in the block, the method further includes:
when a scanning instruction of a consumer scanning the tracing code in the commodity is received, inquiring whether the tracing permit still exists in the commodity, and if so, distributing the tracing permit of the commodity to the consumer; if not, the commodity is judged to be a non-genuine commodity.
Specifically, the traceability certificate of each commodity can be received only once, so that before a consumer receives the traceability certificate, it is first determined whether the commodity still has the traceability certificate, and if the traceability certificate exists, it is determined that the commodity consumption condition is normal, which is the first consumption. If the source certificate is not passed, the commodity is indicated to be consumed, and the commodity may be illegal.
Preferably, after the tracing certificate of the commodity is distributed to the consuming user, the method further comprises:
and recording consumption users, time and places on the blocks storing the tracing data in the commodity on the block chain.
Specifically, in order to ensure the authenticity of the tracing information, after the user receives the tracing certificate, it is indicated that the user has consumed the commodity, and at this time, the consuming user, the time and the location need to be recorded in the blockchain.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
