Description
Technical field
The present invention relates to field of information security technology, specifically a kind of supply chain status data based on block chain is chased after
Track method.
Background technology
With the development of information technology, it is not retrievable one that internet just like has become all trades and professions development institute
Point, especially in enterprise information exchange and data sharing.Information, data sharing between enterprise, except conventional buying, transaction
Etc. the exchange of information, also a kind of special information exchange-supply chain.
Supply chain is around a series of relevant enterprises, by commodity-circulate, information flow, logistics, the control of cash flow, from buying
Raw material start to being made middle and final products and product is sent to one in consumer's hand by production, distribution etc.
The allomeric function structure that links enterprise is constituted.So the information sharing in supply chain is related to production and the pin of many enterprises
Sell, the efficiency of supply chain directly determines the development of enterprise in whole supply chain.
At present, many large enterprises of China have had been provided with good logistics supply chain management ability and very strong logistics
Optimize with supply chain management and realize, but most of medium-sized and small enterprises the aspect such as popularization and application of supply chain management be still within compared with
Low-level.Such situation is greatly, because the backwardness in enterprise management idea is caused, to be on the other hand also due to
Technical reason.And in face of market environment complicated and changeable, realize that efficient supply chain management is inherently not easy very much.
Enterprise in supply chain tends not to grasp useful information accurately and in time.Requirement of the supply chain to enterprise at this stage is first
It is information-based, the enterprise for having carried out informationization is only possible to make good use of supply chain management, and the upstream and downstream firms with supply chain enter row information
It is shared.Yet with technical limitation, at this stage in the supply chain state tracking between enterprise, information share and security is low, raw
The information such as product, logistics exchange more scattered, inadequate system, share dynamics not enough.
So, in this process, between enterprise effectively, accurately pass on information, be supply chain management success or not
It is crucial.The application of new technology is to solving the problems, such as enterprise is likely to occur in supply chain management information asymmetry in supply chain management
It is particularly significant.
Enterprise needs the information content for exchanging larger in supply chain, including enterprise's condition of production, delivery situation, logistics information
Etc. the information of many aspects.Block chain carry out data distribution formula store when, modification of the individual node to database be all it is invalid,
The data stability of block chain is high with reliability.So block chain technology is used for the exchange of information of supply chain and very may be used with shared
By with safety.
However, the multiple departments for needing the information shared more scattered in supply chain and being related in enterprise's production, so
In traditional information sharing of supply chain, because the production schedule change of enterprise is frequent, supply chain down-stream enterprise cannot in time with
Enter the change of upstream firm, this causes supply chain effect in itself not played.
The content of the invention
The invention aims to overcome above-mentioned the deficiencies in the prior art part, there is provided a kind of supply based on block chain
Chain state data tracing method, the method proposes that a kind of new supply chain exchanges the mode of information, and utilizes block chain technology reality

Different department informations are divided into different service lines, every service line by the enterprise that node A is represented according to corporate business situation
Split further according to related service logic, become different coherent service nodes；If the node A information to be uploaded is certain
Information on one service node, then node A need the service node information that will be currently sent, related industry on other service lines
Business nodal information, the following related plan nodal information for occurring are uploaded in block chain in the lump；
（4）According in block chain other each from the legitimacy of the register information checking node A of node, and verify it is legal after make
The authenticity of the data received with the public key verifications host node of node A, storage is by the data verified and the corresponding number of generation
Word fingerprint, the digital finger-print that will be generated is together with corresponding timestamp write-in block chain；
（5）After data write-in block chain, information network interior joint B gets the information of node A uploads and preserves in t, should
Information includes business section related on the information of a certain service node that the enterprise that node A is represented currently occurs, other service lines
Point information and the following related plan nodal information for occurring；
（6）At the t+1 moment, node B receives the information of the follow-up service node for occurring in node A, on t+1 moment other service lines
The related service node information plan nodal information related to the t+1 moment；There is phase in the business information that node B is received twice
With service node, now node B the accurate of supply chain status data is judged according to the similarities and differences of information on identical services node
Property is simultaneously linked up according to result with node A.
In the above-mentioned technical solutions, only host node has the right of modification block chain, is respectively only capable of inquiring about oneself from node
Information uploads record.
In the above-mentioned technical solutions, from node real time record block chain current state, in order to block chain network
When node is destroyed, can be recovered from node from any one.

The inventive method proposes that according to corporate business situation can be divided into different department informations by the enterprise in supply chain first
Different service lines, every service line is split further according to related service logic, becomes different service nodes；Supply chain
In enterprise carry out business information it is shared when, be no longer that Information Sharing is carried out to the current event for occurring, but sharing letter
The service conditions of company is just planned before breath in advance according to above-mentioned partitioning scheme, and present node has just been carried out before information exchange
Plan of operation below.Information then will the current service node information for occurring, related business section on other service lines when exchanging
Point information, the following related plan nodal information for occurring are sent to down-stream enterprise in the lump.Down-stream enterprise is receiving this time
Preserved after information, down-stream enterprise also can receive the service node of follow-up generation and now on other service lines in subsequent time
Related service node information and now related plan nodal information.This information for receiving twice of down-stream enterprise has suitable one
Part is the node for overlapping, if this partially overlaps, the information of node does not change, and illustrates the production schedule of upstream firm
Do not change.If this partially overlaps, the information of node changes, and shows that the production schedule of upstream firm there occurs
Change, down-stream enterprise can judge the change of upstream firm according to different information twice, also can further be linked up with upstream firm
Confirm.And service node information all carries other related service nodes and plan information every time, down-stream enterprise is repeatedly connecing
Judgement can be analyzed according to each information for receiving after receipts.
May be divided into for business event according to business such as buying, production, logistics different by one traditional manufacturing industry company
Then these service lines are divided into different service nodes by service line according to corresponding workflow.This enterprise of family is in one
In supply chain, then when it carries out business information exchanges, just not only only share current generation event, but according to corresponding
The current thing for occurring is associated and shares to down-stream enterprise in the lump with reference to prospective project by buying, production, logistics plan.
This method is based on the supply chain status data method for tracing of block chain, first by clear and definite business event line, segmentation
The mode of service node and then associated services nodal information increases information sharing dynamics between enterprise, makes originally scattered information more
System；Secondly, information is shared during supply chain can be increased by way of the nodal information repeated in related information is verified
