Node is handled, i.e. the executing subject of method can be food information processing node.Node on the block chain includes described in 1
Food information handles node, 1 consumer's management node and at least one supplier management node.Method shown in Fig. 2 mainly includes
Step S101 is specific as follows to step S103:
S101, according to the identity information and public key of each node made an appointment, in cycle time from the block
The encryption information that chain receives carries out authentication, obtains the vendor identity verification result of each encryption information.
Wherein, the encryption information is the private key encryption information that the supplier management node is broadcasted on block chain.Tool
Body, the node on block chain, especially supplier's management node constantly by flow through oneself node processing food information or
Other information is broadcast on block chain, so that all nodes can receive on block chain.Such as it can be supplier management
A collection of food packaging is completed in the every processing of node, is broadcast to block chain after the packaging of the batch is just completed information encryption.It can also be with
Such as supplier management node will just be broadcasted at interval of 24 hours after the information encryption for completing food packaging in previous 24 hours
To block chain.Food information handles node at interval of a cycle time (such as 1 hour or 1 day), to the area period Zhong Cong
The information that block chaining receives intensively carries out authentication.It wherein, is all each node on block chain from the received information of block chain
The encryption information of broadcast.Authentication can be understood as verifying the identity of each encryption information publisher node.Such as
To food packaging class encryption information its mark publisher node be the corresponding supplier management node in packing factory, then need verify with
The public key that the corresponding supplier management node in packing factory is made an appointment, if food packaging class encryption information can be decrypted, if not
It can decrypt, then it represents that the node for encrypting the food packaging class encryption information is not the corresponding supplier management node in packing factory, body
Part authentication failed.
In a kind of concrete implementation mode, supplier management node for example including raw material, adds the food information of oneself
Add, the place of production, process the information such as ground, supplier, according to unified format and after private key encryption and signature, is sent to block
It is closely broadcasted in chain.Other nodes of block chain can receive this food information, and temporarily store.Food information handles node
(such as 1 day), the food information of all nodes were received in a period of time.Food information handles node to the label of these food informations
Name carries out authentication.Authentication includes being verified according to the node identities and public key information that record on wound generation block, is obtained
To food information validation verification result.
The encryption information received in the cycle time from the block chain, it can be understood as be stored in caching
Information can be and be removed or covered over time, such as is removed or covered after 2 cycle times.Believed by food
Breath processing node carries out the authentication of publisher node to these information, so that being not necessarily to each section during block verifying
Point verifies the identity of information publisher one by one, reduces the resource consumption of each node of block chain, shortens subsequent block
Verification time.
S102 generates food information block, and the food information block is broadcasted to the block chain, the food letter
Ceasing block includes the encryption information and the corresponding vendor identity verification result of the encryption information.
Specifically, it can be understood as be to test the encryption information and the corresponding vendor identity of the encryption information
It demonstrate,proves result and generates food information block, then broadcast food information block on the block chain, so that block chain
Upper all nodes receive the food information block.
Food information block mainly includes two parts: block head and block main information.Block head is for local area
Block is identified and the relationship of minute book block and previous block.Block main information is the information of this block record.?
In a kind of implementation, the acquisition process of food information block, which specifically may is that, is determined as the food information for current time
The timestamp of block；The vendor identity verification result corresponding to the encryption information and the encryption information obtains Hash
Value, is determined as the block-identified of the food information block for the cryptographic Hash；With the timestamp of the food information block, institute
It is block head that the block-identified and previous cycle time for stating food information block, which corresponds to the block-identified of block, is added with described
Confidential information and the corresponding vendor identity verification result of the encryption information are block main information, obtain food information area
Block.
For example, food information handles node according to validation verification as a result, generating food information block.Wherein, food is believed
It ceases and records effective food information and invalid food information, and the summation of invalid information and effective information in the block main body of block
It is all food informations that food information processing node receives in 1 day.The block head of food information block then has recorded currently
It is Hash (hash) value (the information hash metaplasia recorded in block main body at value) of block, the timestamp for generating block, previous
The cryptographic Hash of block.
Due to including the block-identified of previous block, each food information in the block head of food information block
It can be mutually authenticated between block, block sequence can not distort.Again because be using the cryptographic Hash of block main information as
It is block-identified, the block head of the block-identified block head for being stored in this block and next block, therefore the block of each block
Main information is also that can be verified, and block main information can not be distorted.As it can be seen that there is food information block information can not usurp
The characteristic changed improves the safety of food information.
The food information block broadcasted on block chain can all be received by all nodes on block chain, and to the food
Information block carries out content verification, obtains the result of content verification.When the number of nodes that content verification passes through is greater than threshold value, such as
80% or more node passes through the content verification of the food information block, then all nodes receive the food information block, and
The food information block is stored in respective node local storage space.Local storage space is different from above-mentioned caching, can be with
Understanding is a kind of memory block stored for a long time.Local storage space for example can be in readable storage medium storing program for executing.
S103, determine the block chain to the verification result of the food information block be by when, by the food
Information block is saved into local storage space.
Specifically, it is determined that the block chain is to pass through to the verification result of the food information block, it can be understood as root
According to all nodes to the verification result of the food information block, verifying of the block chain to the food information block is determined
It as a result is to pass through.In one implementation, it can be the encryption information that will be received in cycle time from the block chain, really
It is set to cache information；The food information block broadcasted in the block chain is received, and obtains the block of the food information block
Main information.Judge encryption information in the block main information of the cache information and the food information block whether one
It causes, if so, node verification result is determined as first kind verification result, if it is not, node verification result is then determined as second
Class verification result.Similarly, each node also carries out above-mentioned judgement when receiving food information block on block chain, obtains
A kind of or the second class verification result.Each node broadcasts the node verification structure to the block chain, and receives the area
The node verification result of all node broadcasts on block chain.Based on same intelligent contract, all node broadcasts on the block chain
In node verification result, if the accounting of first kind verification result, which is greater than or equal to, passes through threshold value, it is determined that the block chain is to institute
The verification result for stating food information block is to pass through.The accounting of first kind verification result can be understood as obtaining first kind verifying
As a result accounting of the number of nodes in block chain total node number amount.Such as a total of 20 nodes of block chain, specifically include 1 food
Product information processing node, 1 consumer's management node and 18 supplier management nodes, wherein 18 supplier management nodes
The supplier either enterprise, group of 18 links on agri-food supply chains are respectively corresponded.To some food information block, 19
A node obtains first kind verification result, and 1 node obtains the second class verification result, and is 80% by threshold preset, then really
Determining block chain is to pass through to the verification result of the food information block, and each node receives the food information block, and by the food
Product information block is saved into local storage space, and it is accurate to the transparency and information of all participants to which thereby enhance food information
Property.
In another example food information, which handles node, is broadcast to all nodes of block chain for the food information block of generation.Block
The record (information that cycle time content is received from block chain) that all nodes of chain are stored according to oneself node believes the food
Breath block is verified.If having more than 50% node confirms that the food information block does not have mistake, all nodes receive the food
Product information block is stored into the local storage space of oneself node.If confirming, the food information block does not have vicious node
Quantity is not up to 50% confirmation in node total number amount, then abandons the food information block, receives supplier management node again
The information of broadcast repeats the above steps, and food information block is just stored local storage space until reaching common understanding.
Above-mentioned steps S103 (determine the block chain to the verification result of the food information block be by when, will
The food information block is saved into local storage space) it is not only the step of food information processing node executes or area
The step of all nodes are carried out on block chain.
A kind of food information processing method is present embodiments provided, handles node applied to the food information on block chain,
Node on the block chain includes 1 food information processing node, 1 consumer's management node and at least one supply
Quotient's management node, by according to the identity information and public key of each node made an appointment, in cycle time from the area
The encryption information that block chaining receives carries out authentication, obtains the vendor identity verification result of each encryption information, described
Encryption information is the private key encryption information that the supplier management node is broadcasted on block chain；Food information block is generated, and
The food information block is broadcasted to the block chain, the food information block includes the encryption information and the encryption
The corresponding vendor identity verification result of information；Determining the block chain to the verification result of the food information block
For by when, the food information block is saved into local storage space, there is food information block information can not distort
Characteristic improves the safety of food information, improves food information to the transparency and information accuracy of all participants, into
And improve be food information reliability.
It is another food information processing method flow diagram provided in an embodiment of the present invention, in above-mentioned reality referring to Fig. 3
