Description
Technical field
The invention belongs to food safety tracing technology field, it is related to a kind of oil and foodstuffs full supply chain based on block chain
Credible retrospect model and its construction method.
Background technique
In recent years, food safety accident, safety problem are commonplace, " tonyred duck's egg ", melamine milk powder ", " trench
The events such as oil ", " cadmium rice " make us startling, and the health of consumer is seriously threatened safely, and the public is to food matter
The requirement of amount safety is continuously improved.Oil and foodstuffs include finished product of grain, raw grain grease etc., are the necessitys in national life, covering
All residents in China ensure the safety of oil and foodstuffs supply, have to national life and health, social harmonious development very great
Meaning.Due to the features such as oil and foodstuffs supply chain is complicated, cycle period is long and risk factors are more, oil and foodstuffs supply ring at present
Section is there are a large amount of safety problem, such as excessive pesticide residues, food origin disease problem caused by industrial pollution, produces and processes link
It operates violation, is illegal using food additives, storing and transporting security problem, product fake and forged commodity etc..It is therefore desirable to improve food to supply
The transparency of chain is answered, and carries out credible, accurately and effectively food safety trace back.
There is prolonged research and development in all respects for the safe traceability system of oil and foodstuffs.Pass through application
Barcode technology, RFID (radio frequency identification) technology and wireless sensor network etc. are detected and are remembered to each link of supply chain
Record, and formulates corresponding information traceable system and Legal System, gradually establish food is identified, is logged in, is tracked and
The information system of retrospect, domestic five more influential agricultural product traceability systems: Shanghai eats agricultural quality safety
Information query system, the retrospect of Beijing Municiple Agriculture Bureau's edible food (vegetables) quality safety, century agriculture-countryside-farmer " trace to the source management by food safety
System ", Chinese beef cattle whole process quality safety system for tracing and managing, national vegetables quality safe tracing system.Tradition retrospect is crucial
There are certain drawbacks, the traceability system established at present uses centralization, the control mode of centralization for technology, system and system,
Acquisition, typing, storage and management from production to the data of the entire supply chain of sale are completed by part core enterprise, therefore number
According to management, there is ability that is imaginary, distorting, delete in enterprise to data；All data are stored in central database, once middle calculation
Attacked according to library, all data of whole system will be destroyed, therefore Information Security have it is to be hoisted；In supply chain link
In section, the reliability that down-stream enterprise provides data to upstream firm is difficult to verify, so as to form the information between enterprise
Isolated island needs to improve at the authentic and valid aspect for guaranteeing information transmitting.Consumer and regulator are to providing the true of information in system
Property, reliability leave a question open.The retrospect of normal food supply chain is to one of agri-food supply chains or certain several link traces, and grain
The supply chain of oil food is sufficiently complex, and risk factors are more, cycle period is long, involve a wide range of knowledge, and the derivative link of each link is many
It is more, or even different link is alternately repeated circulation, such as production link also includes drying the processes such as preliminary working technique, storage, transport,
And in logistics links, province, city, different enterprises at county level are also required to freight house to store product, therefore nested corresponding storage link.
Therefore causing inside and outside source hazardous material to generate, process is complicated and changeable, active specific aim prevention and control difficulty is big.In face of so huge link
With data volume, the resource consumption of traditional food traceability system is big, speed is slow, low efficiency.
The appearance of block chain technology is so that the above problem knows about certainly scheme, to realize that secure and trusted oil and foodstuffs chase after
System of tracing back provides a practical way.Currently, research of the block chain technology in financial field has tended to be mature, and in recent years
Being applied to foodstuff traceability field in block chain has certain research and exploration, but traces to the source in oil and foodstuffs that there has been no elder generations in field safely
Example, the peer-to-peer network (P2P) that is related to, cryptographic algorithm and common recognition algorithm etc. determine block chain technology have decentralization,
Data can not distort, information transparency, the characteristics such as traceable.Changed data can be navigated to step by step by hash function, protected
The every data for having demonstrate,proved each main body in supply chain system can trace, convenient for calling to account and supervising.Common recognition algorithm can ensure that data
Consistency, the data tampering behavior of single node will receive all monitoring nodes of the whole network and repulsion, therefore ensure that information flow
It is logical and Trading parties data open and clear, broken problem of detached island of information existing for legacy system, realize supply chain circulation,
The data record of transaction, information transmitting, can guarantee the reliability, accuracy and the transparency of data.Food safety thing is occurring
Therefore when, food traceability system can be quickly and accurately positioned the link of problem generation, and find the root of problem, tracing problem production
Product whereabouts, clearly defining responsibilities enterprise simultaneously call to account, and reduce adverse effect caused by food safety accident, ask food safety is solved
Topic has a very important significance.

Specific embodiment
Below with reference to example, the present invention is described in further detail.
The embodiment of the present invention realizes the building process of the credible retrospect model of the oil and foodstuffs full supply chain based on block chain, packet
Following steps one are included to step 5, illustrate each step below.
Step 1: analysis oil and foodstuffs full supply chain link.
By understanding related grain and edible oil mills, and field research oil and foodstuffs factory, such as certain flour mill
Production and processing process, design are eaten by the grain and oil that production link, processing link, storage link, logistics links and sales section form
Product full supply chain link, as shown in Figure 1.
The information of each link acquisition is by being stored in the traceability system based on this model construction after verifying, to establish true
Real reliable full database, may be implemented to carry out the entire supply chain of same batch products complete supervision and retrospect.
Production link, which refers to, harvests oil and foodstuffs, records its relevant information, including implantation time, harvest time, product batches etc..
Processing link includes the work such as drying process, decladding, processing to harvest product and records information, including product number, processing
Process etc..Storage link records its storehouse information, such as storehouse numbers, enters the outbound time.Logistics links include harvest product
And after processing finished product logistics transportation, such as haulage vehicle, conveying people.Sales section, which refers to, carries out the finished product completed the process
Sale, record selling spot, salesman etc..To complete the prison of the entire supply system from oil and foodstuffs harvest to sale of finished goods
Pipe and retrospect.
Step 2: establishing the credible retrospect model of oil and foodstuffs full supply chain, cloud database is uploaded data to.
For oil and foodstuffs production and the supervision and trace back process of intermediate links, in conjunction with block chain technology, design and supply
The corresponding enterprise's node of chain link establishes the credible retrospect model of oil and foodstuffs full supply chain, as shown in Fig. 2, production link, plus
Work link, storage link, logistics links and sales section respectively correspond node 1, node 2, node 3, node 4 and node 5.
Due to oil and foodstuffs full supply chain be in agri-food supply chains it is most complicated, based on the more feature of its link, from life
Producing sale needs acquisition, record, the total data amount of upload very huge and complicated, and being stored on block chain will appear cost
High, the problem of burden is big, low efficiency, therefore huge product basic data is stored in cloud database by the present invention, then by cloud data
Basic data in library carries out the cryptographic Hash deposit block chain that Hash operation obtains together with the label data of Product labelling information
In, to guarantee the cost and efficiency of block catenary system operation.
The oil and foodstuffs data that each enterprise's node is uploaded to block chain will follow the constraint of intelligent contract, only meet intelligence
The data that energy treaty conditions require could upload success.Since the data format that different enterprise's nodes upload is not quite similar,
The multi-source heterogeneous data of different enterprise's nodes carry out the unification of data format by intelligent contract, and basic data passes through number again
Signature technology is verified data and is uploaded and stored to cloud database.Basic data is uploaded to the detailed process of cloud database
Are as follows: Hash operation is carried out to obtain data summarization to a large amount of basic datas of product, system is generated by Asymmetric Cryptography
Public key and private key encrypt data summarization by private key, and encrypted data summarization is as signature value together with basic data
After uploading to cloud database, cloud database can be decrypted the encrypted data summarization (signature value) received by public key,
Data summarization after the completion of decryption is compared with to basic data with the data summarization that same Hash operation method obtains, if right
It is more consistent than result, it proves that data are true and reliable and is not tampered, a large amount of basic datas are smoothly stored in cloud database；If result is not
Unanimously illustrate that data have passed through to distort then not by verifying, database can not be stored in.By digital signature technology, each enterprise's section
The data of point deposit cloud database are effectively credible, therefore the authenticity of a large amount of basic datas is guaranteed in cloud database.
Step 3: the structure of design data block.
The cryptographic Hash of basic data in the Product labelling data and database of each link in oil and foodstuffs full supply chain
Common operation obtains root cryptographic Hash, and enterprise's node through safeguarding alone is uploaded and broadcasted to the block chain node of the whole network, the whole network institute
Have block chain node by common recognition process verification after be stored in newest data block, and on chain to upper level data block to
It completes by the process of data deposit block chain, as shown in Figure 3.Wherein block head encapsulates parent block cryptographic Hash, current block version
This number, timestamp, the cryptographic Hash of current block etc., block body include the brief information data (day by a certain link of verifying
Phase, product batches etc.) and database cryptographic Hash.
Trace back process are as follows: the traceability system of consumer-user or regulatory agency model through the invention inputs to be checked batch
Secondary product code is traced, and product code is directly targeted to the given zone build comprising this product information, recalls this product
All intermediate links data carry out product back-tracing.
The data of node input are stored in data block by uploading and after verifying of knowing together, the number generated to different links
According to the identification code for forming 32 before the root cryptographic Hash in the block head of block plus 16 codings of corresponding batch products, every number
One is stored according to the corresponding 32 bit identification code of block to be specifically used to store in the data block of identification code.Before same batch products
16 codings are identical, and rear 16 codings of different links are different, and the traceability code in consumer's hand is finally generated according to identification code.In
When retrospect, for consumer by inputting traceability code in system, system navigates to identification code area automatically according to identical preceding 16 codings
The identification code of same batch products in block identifies the corresponding data block of all link data of this batch products, passes through ratio
All data of storage within a block are traced back to identification code, while being shown data in Web system by server end,
Complete the retrospect to product.
Step 4: establishing intelligent Contract Model.
For a large amount of multi-source heterogeneous oil and foodstuffs data, data are handled by intelligent contract, it will not apposition
It can be uploaded after formula, different type, the data of different length are unified, do further common recognition verifying.
The implementation procedure of intelligent contract is as shown in figure 4, the business manager of each link is according to actual requirement system in supply chain
Determine terms of agreement content, intelligent contract is set according to terms of agreement to the preset trigger condition of data processing, when data upload,
Judge whether data meet the call format of upload, if the data format that the acquisition of current enterprise node uploads, which meets, is deployed to block
The prerequisite of catenary system intelligence contract, then data can be uploaded and continue the integrity verification of next step.If number
Prerequisite is not met according to format, then data is handled by preset code and is judged again, can be carried out later next
The data integrity validation of step.For the full supply chain of oil and foodstuffs, transaction, information transmitting between links etc. according to
It is carried out according to the intelligent contract made.
Intelligent Contract Model framework is write and is generated contract code as shown in figure 5, the specified treaty content of contract each side, compile
It is published to after translating on all nodes of block catenary system, each node verifies the validity of treaty content, and all nodes are logical
The whole network casting completion deployment is carried out after crossing common recognition verifying, the contract after deployment is stored in block catenary system, reaches trigger condition every time
When can call and run automatically.The data format of some node is verified the intelligent contract-defined interface of calling to execute, and data upload
When reach trigger condition contract and start to execute, whether each node verification result correct after being finished, after being verified, area
Block catenary system can broadcast the result of execution to each node of the whole network, and the data of upload are deposited into newest data block
In.
Step 5: forming agri-food supply chains block serobila system structure.
In agri-food supply chains field, the framework of block chain can be divided into: data Layer, network layer, common recognition layer, contract layer and application
Layer.As shown in Figure 6.Data Layer includes that different enterprises upload the food related data verified by common recognition mechanism, is stored in distribution
The data block of database, data block is connected in chronological order constitutes block catenary system.By specific hash algorithm and
Merkle data tree structure, by deposits such as the Food circulation data, the transaction data that are received in a period of time with timestamp and
The data block of root cryptographic Hash；Network layer encapsulates networking mode (P2P network) and data authentication mechanism of block catenary system etc.
Element；Common recognition layer is built a consensus mechanism, is known together algorithm comprising PoW, PoS, BFT, PBFT etc., alliance's block linkwork of field of food
System, realizes each node needle using share authorisation verification (DPoS) and practical Byzantine failure tolerance algorithm (PBFT) more agreed with etc.
The validity of food data is reached common understanding；Contract layer encapsulates the contract script generation that each node executes on the agri-food supply chains of foundation
Code, the execution of the intelligent contract based on block chain execute automatically when reaching expected trigger condition；Application layer includes food supply
Each enterprise client of chain and user and supervision department carry out the client of retrospect inquiry.
Embodiment 1:
By carrying out research study on the spot to Hebei flour mill, the data of each production link are obtained, this grain and oil is eaten
Product full supply chain is credible retrospect model feasibility carry out analysis verifying.Using the credible retrospect model of oil and foodstuffs full supply chain as core
The heart builds the credible retrospect prototype system framework of oil and foodstuffs full supply chain according to the flour mill is practical, including oil and foodstuffs
P2P network, cloud database and the traceability system groups of clients that data collection station, the distributed node of full supply chain link are constituted
At as shown in Figure 7.The flour mill is related to the complete supply chain link sold from harvesting wheat to flour, comprising harvesting wheat, does
Dry working process, storage, flour processing, packaging, storage, Product transport and sale etc..Since flour mill's intermediate links are examined
It is low, not tight to check on to look into dynamics, and enterprises operation violation, interests manage not in place, final milling product caused by driving
There are quality problems, in addition the data from production to sale are excessively huge, it is difficult to carry out data query, defective in quality is a certain
Batch products can not navigate to specific link, can not precise responsibilities main body, caused by consequence be seriously but difficult to solve.
In conjunction with the credible retrospect model of oil and foodstuffs full supply chain provided by the invention and system architecture, it is complete to build oil and foodstuffs
The prototype system for retrospect that supply chain is credible, as shown in figure 8, providing solution for the above problem.
Prototype system is made of front end webpage, server, cloud database and block chain network.Front end webpage uses front end language
Speech (HTML, CSS, JavaScript) is simultaneously aided with Bootstrap+AngularJS Development of Framework, server section by
WebService technology realizes that block chain network is developed based on Hyperledger Fabric Open Framework.In data input ring
Section, uploads product relevant test data, and when data format is legal, database is written after verifying.Harvesting wheat it
Afterwards, test lot product data make unique product IDs to block catenary system according to the present invention, and product IDs follow this batch to produce
The production and processing of product requires to be passed to next link, and processing, storage, logistics and sales section scan the product batch of a upper link
Subcategory number, and information is uploaded into block catenary system.If artificially being modified in processing link traceability code, due to traceability code according to
The cryptographic Hash of product batches code and data block obtains, therefore can not be with the Kazakhstan in database when storing in a warehouse link scanning traceability code
Uncommon value corresponds to, and cannot be verified by common recognition in block catenary system, data can not be stored in database.So appointing in supply chain link
What data tampering behavior can be all detected, and guarantee the authentic and valid of data.Finally when detecting, pass through traceability system client
Input traceability code carries out the total data that inquiry obtains product, as shown in Figure 9, Figure 10, since storage link processing is improper, causes
Product quality is not up to standard, can be with precise positioning to the storage link to go wrong by data comparison.
If the inspection of flour occurs slipping and defective product is not arrived by supervision department's sampling observation, defective product is sold to consumption
It is whether consistent by retrospect contrast product ID in person's hand, if the product IDs in consumer's hand by distorting, are tracing results page
It can position rapidly to corresponding problem Risk factor, recall defective product to reduce damage sequence and punish to owner,
Reinforce the quality safety for guaranteeing the supervision of problem Risk factor milling product.Therefore oil and foodstuffs full supply chain of the invention can
Letter retrospect model come realize product traceability be it is feasible, all links of flour mill's products in circulation can be covered, can ensure grain and oil eat
Quality and consumers' rights and interests and health.
