Corresponding data backup；
It is not directly by the raw information of drug and enterprise in the present invention for the business privacy and interests of enterprise
What true identity information was issued on block chain, but just issued after carrying out corresponding information pre-processing.I.e. by medicine
The initial data of product is encoded according to relevant criterion, forms bar code or RFID label tag is bundled in packaging, be then based on this
Label information calculates its cryptographic Hash, is stored in the cryptographic Hash as metadata on block chain, and believes with enterprise's true identity
Breath carries out public key and role of the company information of matching publication for enterprise, by public key and the role of above-mentioned drug metadata and enterprise
It as drug tracing information, is issued on block chain, so that each block chain node possesses and the drug tracing information
Corresponding data backup.
S104, it is traded based on the drug flow on preset Trading Model building block chain, what block chain was recorded in realization
Drug tracing information is updated.
For the ease of to medicine information management and record, by the process of circulation of drug correspond on block chain for one friendship
Easily, for example, a box drug is transported from A to B in physical world, a transaction is initiated to B for A in reflection to block chain.At this
Preset Trading Model is used in inventive embodiments to record the workflow in the drug traceability system, thus to circulating
The information of drug afterwards is updated and is recorded in real time.
Specifically, having redefined transaction data structure, transaction output data structure and block head in the Trading Model
Data structure enables to the Trading Model more to meet the related application in drug traceability system.It realizes to existing area
The extension of the UTXO model of block chain application, UTXO model is a kind of Trading Model of block chain, and drug traceability system is a set of
Physical message system, drug circulates information in existing actual provision chain network, also there is the record in tracing information system.In order to incite somebody to action
Be mapped, drug traceability system constructs entire workflow using a kind of UTXO model of extension.
From referring to fig. 2, for bit coin UTXO model, in bit coin system, a bit coin of transaction value one is transferred accounts,
Comprising fields such as input, comfortable and versions, output includes quantity, the locking fields such as script and version, input include unlock script,
The fields such as transaction Hash, output index and version.The output of transaction shows the bit coin quantity transferred accounts and recipient, receives
Side is embodied by locking script, and the people that can provide corresponding locking script is the bit coin that this stroke count amount can be used, commonly
Bit coin transfer accounts, locking script is public key verifications script.To UTXO model structure in drug traceability system of the invention
It is extended, as shown in figure 3, increasing following field newly: metadata, type, life cycle and block life cycle.Type refers to
The type traded in system, each type all corresponds to a link in practical Drug supply chain, for example, may include: life
Produce, leave, reaching, being packaged, beat again packet, unpack, cancelling and storing trimming etc..
The drug flow transaction of drug traceability system can be more in line with based on the UTXO model after extension.
S105, in response to medicine information inquiry request, Transaction Inquiries are carried out on block chain, the transaction that inquires is carried out
Parsing, obtains the practical circulation information of the drug.
Query service is carried out by query service provider, is specifically included that
In response to medicine information inquiry request, the corresponding member of the drug is obtained by drug query service provider
Data；
It is retrieved on local block chain according to the corresponding metadata of the drug, obtains the institute comprising the metadata
There is transaction；
The All Activity is parsed, the practical circulation information of the drug is obtained.
Specifically, the initial data of drug is encoded according to relevant criterion, bar code or RFID label tag binding are formed
On Key works Drug packing.Enterprise in supply chain is by scanning above-mentioned bar code or RFID label tag, the initial data after being encoded
And its cryptographic Hash is calculated, this cryptographic Hash is denoted as metadata, stores metadata on block chain, and metadata can be by as drug
The index of inquiry.When query service provider handles inquiry request, first according to the metadata retrieval local block of the drug
Chain finds all transaction comprising the metadata, and parses All Activity, the practical circulation situation of the drug is obtained, by the medicine
The corresponding information of the practical circulation situation of product returns to request sender as feedback information.
The present invention provides a kind of drug information management methods, after carrying out Role Management and authentication to enterprise, so that
The node that enterprise is all used as block chain, and based role management and authentication are participated in, enterprise's equity is joined
With, possess identical permission, and pre-process to drug raw information and enterprise identity information, it can be to drug raw information
It is hidden with the true identity information of enterprise, ensure that the business privacy of enterprise, while can based on preset Trading Model
Drug flow transaction is constructed according to type of transaction, so that the publication of Transaction Information is more accurate and timely, to improve drug
The efficiency and accuracy of tracking of information.
Based on the above embodiment, the work of different type of transaction is flowed into using Trading Model provided by the invention below
Row description.
A kind of transaction errors correcting method is provided in another embodiment of the invention, this method comprises:
When recording drug ownership transfer by the preset Trading Model, by the sender of drug and practical reception
Side carries out transaction record as recipient simultaneously；
When the error of the public key of the practical recipient, the drug received is carried out again by the sender of the drug
It issues, realizes the change to original transaction.
Drug ownership turns in all corresponding practical logistics of most of transaction in drug traceability system based on block chain
It moves.If drug corresponding bit coin when drug is shifted with logistics, is recorded in system also by Trading Model, that is, UTXO model
The transfer of drug ownership, similar with bit coin, the practical recipient of only drug has permission the drug that will be received and issues again.
Therefore, if when using traditional UTXO Trading Model, the recipient added in discovery information system after Drug Flow issues is public
Key error, this transaction can not be changed at this time, and will lead to after recipient receives goods can not carry out this batch of medicine in information system
Operation, can not track so as to cause this batch of medicine in information system.To solve the above-mentioned problems, in Trading Model of the invention
When the transaction that treatment of pharmaceutical products ownership is shifted, additionally can increase a recipient to be oneself is current sender, once
It was found that error, can initiate a transaction by current sender again and correct.
By taking the UTXO model after Trading Model is extension as an example, generates a transaction and be used to indicate the production of drug, reach
It is as follows with the step of leaving:
S201, type of transaction is determined, wherein the type of transaction can be production, reach or leave；
S202, all UTXO account books are synchronized；
S203, the relevant information of drug is read from Key works Drug packing；
S204, the cryptographic Hash for calculating the information read in S203, obtain metadata；
S205, it is retrieved in UTXO account book according to metadata, if the not record of the drug, and this this operation is not raw
It produces, then it is assumed that this batch of drug is illegal, is no longer handled；
If S206, the record for finding drug in S205, continue the body that relevant manufactures are inquired to query service provider
Part carries out a step card；
S207, a transaction is generated, the data structure of transaction is as shown in figure 3, include the information such as metadata, type；
S208, the transaction is broadcasted.
Actual Drug supply chain is extremely complex, and steps described above can not cover all actual transaction classes
Type.Type of transaction further includes being packaged, beating again packet and unpack, for example, production and final sales are all minimum packages, and is being transported
It needs to be packaged in journey, vanning, if situations such as encountering breakage, it is also necessary to unpack and repack.For these different packagings
Grade, by designing corresponding mechanism of exchange, so that the transaction in information system can preferably correspond to the drug in physical system
Circulate situation.
UTXO Trading Model can be multiple-input and multiple-output, for the drug of Different Package grade, for example, will be many small
Box is packaged as bigger packaging, then the input by the output of the corresponding transaction of these capsule drugs as current packaging transaction, output
Then the new metadata packed greatly of addition, this transaction issue oneself by oneself, then complete to be packaged transaction in information system, right
Answer the practical packing link in physical system.
When UTXO Trading Model handles above-mentioned transaction, above-mentioned transaction is defined as target transaction, i.e. the target transaction packet
Include but be not limited to be packaged transaction, unpack transaction and one of packaging transaction again.It is corresponding, the processing method are as follows:
In response to being target transaction with the type of transaction, the account book information in the Trading Model is synchronized；Described in acquisition
Corresponding first metadata of target transaction original packaging, and first metadata is retrieved in the account book information,
If retrieving drug record corresponding with first metadata, the second of the corresponding target packaging of the target transaction is obtained
Metadata；
Correlation between first metadata and second metadata is verified, if being proved to be successful, is given birth to
At the Transaction Information of the target transaction；
The Transaction Information is broadcasted on the block chain.
Wherein, original packaging is the initial packaging of drug, and target is packaged as needing during circulation to original packet
Packaging after dress change is packaged transaction for example, corresponding to, then original packaging is the inner wrapping of drug, and target is packaged as being packaged
Big packaging afterwards；For transaction of unpacking, original packaging is big packaged configuration, and target is packaged as inner wrapping form；For packing again
Transaction, original packaging are the packaging of the first seed type, and target is packaged as the packaging of Second Type, and the first kind and Second Type are not
Together.
I.e. when the processing of UTXO Trading Model is packaged, unpacks and pack transaction again, need to determine input according to type of transaction
Then the metadata of packaging determines that corresponding metadata is packed in output, then carries out input in UTXO and pack corresponding metadata
Verifying, then judge to output and input the correlation between metadata, to generate transaction.
Wherein, being packaged transaction may include:
In response to being to be packaged transaction with the type of transaction, the account book information in the Trading Model is synchronized, wherein described
It is packaged transaction characterization drug and the transaction packed circulate greatly is packaged by inner wrapping；
The corresponding metadata of drug inner wrapping is obtained, and the corresponding metadata of the drug inner wrapping is believed in the account book
It is retrieved in breath, if retrieving drug record corresponding with the metadata, obtains the corresponding metadata of the big packaging of drug；
By the corresponding metadata of the inner wrapping and corresponding its correlation of metadata validation of the big packaging, if verifying
Success then generates the Transaction Information for being packaged transaction；
The Transaction Information is broadcasted on the block chain.
It is opposite with transaction is packaged, it unpacks, is by one big packaging as input, multiple inner wrappings are as output.Here is
For to pack again, it is illustrated:
S301, type of transaction is determined, type is attached most importance to packaging here；
S302, all UTXO account books are synchronized；
S303, damaged big packaging acquisition relevant information is read；
The cryptographic Hash (SHA256) of information is obtained in S304, calculating S303, obtains metadata；
S305, it is retrieved in UTXO account book according to metadata, if the not record of the drug, then it is assumed that this batch of drug is non-
Method is no longer handled；
If it is legal to think in S306, S305, all inner wrappings being successively read in damaged big packaging obtain related letter
Breath.
S307, the cryptographic Hash for calculating all inner wrapping information got in S306, as metadata.
S308, by the metadata of inner wrapping, whether they are related to the metadata validation packed greatly；
If being verified in S309, S308, a new transaction is generated, inner wrapping is repackaged into new big packet
Dress, adds new metadata etc..
S310, broadcast transaction.
A kind of storage pruning method is additionally provided in embodiments of the present invention, comprising:
Corresponding piece of life cycle of the block chain and transaction life cycle are set, wherein described piece of life cycle passes through
The maximum value of the life cycle of All Activity is determined in block, and the transaction life cycle passes through the practical shelf-life of drug
It is determined；
The first block of the block chain and the timestamp of the last one block are obtained respectively；
The temporal information for obtaining the first block is calculated according to the timestamp, and obtains the block Life Cycle of first block
Phase；
Judge first block temporal information whether be more than first block block life cycle, if it is,
Delete first block.
The characteristics of block chain is that all nodes can all store complete data, as time goes by, participates in the storage of node
Burden can be increasing, traces this special scenes for drug, devises storage pruning method to guarantee whole block chain
Size keeps in the reasonable scope, mitigating the storage burden for participating in node.Cardinal principle is to increase " block life cycle " and " life
Period " field is abandoned if the time that first block of block chain stores has been more than block life cycle.Wherein, block is raw
The life period is to be determined by the maximum value of the life cycle of All Activity in block, and the life cycle of transaction is the reality by drug
What the border shelf-life determined.It can be obtained by the timestamp of first block and the timestamp of the last one block of the block chain
The temporal information of first block, the temporal information characterize the block there are the times.The life cycle of first block is obtained,
Whether the temporal information for judging first block is more than its life cycle, if so, first block is deleted, if it is not, not doing then
Any processing.It should be noted that above-mentioned storage pruning method can be only applied on first block, guarantee the line of block chain
Property trackability.
Since the pruning method is only applied on first block, it is possible to first block does not arrive life cycle also, but
Second block has arrived, and system will not trim at this time, until first block is to life cycle, will be deleted first area at this time
Block, then second block has reformed into first block, can also be deleted at once.And so on, due to having for drug itself
The effect phase be it is stable, system can reach dynamic equilibrium in long-term operation.
