Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with embodiment, it is clear that described reality
Applying example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field
Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
Block chain technology because of its decentralization, the characteristics such as can not distort, can audit and be widely used in number and deposit card, supply
Chain finance, medical privacy information protection, electronic bill, resource is credible fields such as shared.It can help to join by block chain technology
A set of faith mechanism is quickly set up with each side of block chain, to greatly push the development in digital financial field, and area
Block chain technical operation mechanism more efficient, more and more enterprise institutions and personal user tend to arrive digitalization resource storage
It is as shown in Figure 1 a kind of schematic diagram of block chain network in block chain.
Block chain network in Fig. 1 includes client, endorsement node, common recognition node and submits node.Usual user passes through
Client sends transaction motion to endorsement node, and endorsement node carries out user identity and transaction legitimacy after receiving transaction motion
Verifying, is back to client for verification result；Client verifies verification result, will be in transaction motion after checking and finding correct
It is packaged to cochain content, and the packaged data is sent to common recognition node；Common recognition node is ranked up the packaged data
Afterwards, the block that the data after sequence are new according to block strategy generating, and the block is sent to submission node, submit node pair
Transaction in block is verified, and carries out uplink operation to data after the completion of verifying.
With the fast development of internet, more and more Internet companies have all been pushed outwardly content catering service, because
This can all generate a large amount of data daily, what which usually exponentially increased, and inevitably, criminal also can be
The some illegal contents of interconnection Web realease or content of maliciously starting a rumour are removed due to the characteristic that the decentralization of block chain can not distort
The non-block chain network cut off in whole network on all nodes or joint are more than that the node of 51% or more the whole network removes modification chain
Upper data, otherwise can not delete illegal contents or malice is started a rumour content, once therefore illegal contents cochain, will be to society and phase
It closes individual and causes irremediable loss.
Based on this, Some Enterprises can audit cochain content, and auditing standards and sensitive content library are formulated by enterprise
And incomplete disclosure is as it can be seen that audit behavior is also dominated by enterprise side completely.For personal or company interest, cancels or shield without authorization
The phenomenon that covering the upload content of content provider happens occasionally, therefore the content auditing mode is short of fairness and reasonability.
On the basis of the above problem, the embodiment of the present invention provides transaction endorsement method, apparatus, area in a kind of block chain
Block chain network, server and user terminal；The technology can be applied in block chain technology in the scene of data cochain, especially
The scene that content in block chain to uplink data is audited.
For convenient for understanding the present embodiment, first to the transaction in a kind of block chain disclosed in the embodiment of the present invention
Endorsement method describes in detail, and this method is applied to the endorsement node in block chain, as shown in Fig. 2, this method includes as follows
Step:
Step S202 receives the transaction motion from client；It wherein, include to cochain content in the transaction motion.
The client can be mounted in answering on the mobile terminal (such as mobile phone, tablet computer) or computer of user
With program, the SDK (Software Development Kit, Software Development Kit) being also possible on computer.It is above-mentioned to
Cochain content is usually that user wants text, picture or video for uploading etc..In addition to cochain content, above-mentioned transaction motion is logical
It often further include subscriber identity information, Transaction Information etc..
Step S204, simulation execute the intelligent contract on above-mentioned block chain, with audit to cochain content, obtain audit knot
Fruit.
Above-mentioned intelligence contract is usually a kind of computer protocol that contract is propagated, verified or executed in a manner of information-based, should
Intelligent contract is usually the chain code write on block chain, which can encode transaction assets, and wherein trading instruction can
With modification transaction assets.In instantiation, intelligent contract needs endorsement to order strategy, which usually requires endorsement to order
Node endorses to transaction, it is understood that can verify or state whether transaction is legal for endorsement node.
In specific implementation, it is interacted by the SDK of client and block chain network, the intelligence on block chain can be called
Energy contract (alternatively referred to as chain code), and endorsement node is used as according to the node of verifying demand selected part audit side, so as to
Corresponding endorsement strategy is generated, one or more endorsement node is generally included in endorsement strategy.For example, the chain code of endorsement strategy
It can write are as follows: peer chaincode instantiate-C<channelid>-nSensitive-Chaincode-P " AND
('Org1.peer','Org2.peer','Org3.peer')"；In the endorsement strategy only have Org1.peer, Org3.peer and
Tri- endorsement nodes of Org3.peer, which are all endorsed, to be passed through, this endorsement process just calculates real completion.
After client sends transaction motion, each endorsement node in endorsement strategy can receive transaction motion,
Then whether the subscriber identity information in each endorsement node verification transaction motion meets preset requirement, if met the requirements,
Then simulate execution (auditing result will not be usually recorded in block chain after executing intelligent contract to cochain content by simulation) intelligence
Contract, which can carry out content auditing to cochain content in transaction motion, to obtain to cochain content legality
Or illegal auditing result.Wherein, whether it is illegal contents or evil which usually audits to cochain content
Meaning is started a rumour content etc..
Step S206 generates endorsement as a result, the endorsement result is back to client according to above-mentioned auditing result.
Node endorse according to the legitimacy of the auditing result to cochain content, corresponds to and generates endorsement result.In to cochain
When to hold auditing result be legal, the endorsement result of corresponding endorsement node is that endorsement passes through, when being to cochain content auditing result
When illegal, the endorsement result of corresponding endorsement node is that endorsement does not pass through.Endorsement result is back to client by endorsement node, such as
All endorsement nodes, which are endorsed, in fruit endorsement strategy passes through, and client will be sent to common recognition node to cochain content；Common recognition section
Point is treated cochain content and is ranked up, and new block is generated further according to block generation strategy, and sends block to submission node；It mentions
It hands over node to verifying in block to cochain content, cochain content is treated after the completion of verifying and carries out uplink operation.If back
All endorsement nodes have one or more endorsement not pass through in book strategy, will upload failure to cochain content.
The present invention provides a kind of transaction endorsement method in block chain, this method is applied to the endorsement section in block chain
Point, this method receive the transaction motion from client first；Then simulation executes the intelligent contract on block chain, is handed over auditing
In easy motion to cochain content；Endorsement is finally generated according to auditing result as a result, and endorsement result is back to client.This
The intelligent contract that invention is endorsed on node by block chain is audited to cochain content, not by the full powers control of any individual or entity
System, thus the auditing flow is open and clear, avoids auditing result by interference caused by subjective factors, to improve in block chain cochain
Hold the fairness and reasonability of audit.
The embodiment of the present invention also provides the transaction endorsement method in another block chain, and this method is described in above-described embodiment
It is realized on the basis of method；The specific mistake to cochain content is audited in the description of this method emphasis by the intelligent contract on block chain
Journey；As shown in figure 3, this method comprises the following steps:
Step S302 receives the transaction motion from client；It wherein, include to cochain content in the transaction motion.
Step S304 calls preset content auditing algorithm by the intelligent contract on block chain；Wherein, which examines
Accounting method operates on endorsement node.
Above-mentioned preset content auditing algorithm is usually filtering sensitive words algorithm, and filtering sensitive words algorithm can use DFA
(Deterministic Finite Automaton, determine finite automaton) algorithm.The feature of the DFA algorithm are as follows: have one
Finite state set and some sides for leading to another state from a state, each edge are marked with a symbol, one of them
State is initial state, and certain states are final state, it is understood that is available by current state state and event event
Next state next state=event+state is illustrated in figure 4 the flow chart that state is converted in DFA algorithm.
S, U, V and Q indicate state in Fig. 4, a and b expression movement, usually can according to be input in DFA event (
Can be understood as to cochain content), it determines and is acted by which from a state to another state.In filtering sensitive words
It is not event and state conversion, and is to look for, if any sensitive word " Chinese spy " and " trade war ", it is necessary first to construct quick
Feel word data structure, as shown in Figure 5.As shown in Figure 5, if the sensitive word for having multiple initial characters different will constitute more it is independent
All initials can be stored in individual lead-in superclass by keyword tree in order to improve search efficiency.
When being stored with 1577 sensitive words in the corresponding local library of DFA algorithm, DFA algorithm is obtained and has carried out sensitive word knowledge
Other average time-consuming and accuracy rate, as shown in table 1.DFA algorithm carries out sensitive word and identifies consumed average time as shown in Table 1
Considerably less, accuracy rate is also higher.
Table 1
Step S306 audits algorithm audit to cochain content through the above, obtains auditing result.
Above content audit algorithm can be audited to which whether cochain content is illegal contents or content of maliciously starting a rumour, usually
Can be determined to which whether cochain content includes sensitive word to which whether cochain content is legal by auditing, and obtain auditing result.
So being audited by content auditing algorithm can be realized to cochain content by following step 01-03:
Step 01, judge to whether include preset sensitive word in cochain content；If quick to not include in cochain content
Feel word, executes step 02；If executing step 03 to include sensitive word in cochain content.
Above-mentioned sensitive word is usually to relate to political affairs, relate to Huang, relate to the words and phrases such as sudden and violent.It will be corresponding with content auditing algorithm to cochain content
Sensitive dictionary is matched, and matching result is obtained；Wherein, the cryptographic Hash of sensitive dictionary and the sensitivity dictionary, is stored in block
On chain；If matching result is that it fails to match, determine to not include sensitive word in cochain content；If matching result be matching at
Function is determined to include sensitive word in cochain content.
Above-mentioned sensitivity dictionary is usually the set of the related sensitive word pre-established.The sensitivity dictionary is laggard by encrypting
It is uploaded to block chain together with Hash (cryptographic Hash) after row base64 coding, any node in block chain alliance is wanted
Update sensitive dictionary, it is necessary to by other members agreement in alliance, the sensitive dictionary that is encrypted on block chain and Hash pairs corresponding
Owner is open and clear, therefore any node is all difficult to distort sensitive dictionary privately, to prevent because of individual interests without authorization
The phenomenon that distorting sensitive dictionary, while also safer legal Vaporous atomization is brought to the supplier to cochain content.
Step 02, determine that auditing result is legal.
Step 03, determine that auditing result is illegal.
Step S308 generates endorsement as a result, the endorsement result is back to client according to above-mentioned auditing result.
Transaction endorsement method in above-mentioned block chain, receives from after the transaction motion of client through the intelligence on block chain
Energy contract calls preset content auditing algorithm, and is audited by the content auditing algorithm and obtain auditing result to cochain content,
Endorsement is finally generated as a result, the endorsement result is back to client according to above-mentioned auditing result.Which calculates content auditing
Method operates on endorsement node and treats cochain content and audited, it is ensured that auditing each time is examined by endorsement node
Core is controlled by Content Management side's full powers, and auditing flow is open and clear and can audit, simultaneously because content on all block chains
It can not distort, therefore the cochain content after can auditing automatically to content better adapts to the requirement currently supervised.
The embodiment of the present invention also provides the transaction endorsement method in another block chain, and this method is described in above-described embodiment
It is realized on the basis of method；This method emphasis description content audits the determining detailed process to cochain content legality of algorithm, and
The detailed process of endorsement result is generated according to auditing result；As shown in fig. 6, this method comprises the following steps:
Step S602 receives the transaction motion from client；It wherein, include to cochain content in the transaction motion.
Step S604 calls preset content auditing algorithm by the intelligent contract on block chain；Wherein, which examines
Accounting method operates on endorsement node.
After endorsement node receives transaction motion, simulation is executed into the intelligent contract on block chain, which will adjust
Carry out content auditing with content auditing algorithm (for example, filtering sensitive words algorithm DFA), with check on the endorsement node to cochain
Whether content includes sensitive word.
Step S606, audits algorithm judges to whether include preset sensitive word in cochain content through the above；Such as
Fruit is above-mentioned to not include sensitive word in cochain content, executes step S608；If above-mentioned to include sensitive word in cochain content, hold
Row step S612.
It is segmented firstly the need of cochain content is treated, the sensitive word in obtained word segmentation result and sensitive dictionary is carried out
It compares, if preliminary audit survey result is no sensitive word without sensitive word in the word segmentation result, in order to ensure the accuracy of judgement needs
It treats cochain content and carries out secondary audit；If having sensitive word in the word segmentation result, will directly be determined as non-to cochain content
Method that is to say that auditing result is illegal.
Step S608 calls third party's service audit to cochain content by preset network interface；Execute step
S610。
Step S610 determines that auditing result is legal if the audit of above-mentioned third party's service passes through；Execute step S614.
Above-mentioned third party's service is usually the preset audit algorithm of demand according to audit side, for example, cochain can be treated
Content such as is segmented, goes stop words, removes meaningless word at the processing, then is extracted to the content characteristic that treated to cochain content
(content characteristic may include the corresponding word feature of content, text style feature and semantic feature) then uses classifier pair
Content characteristic is filtered, and obtains filter result；The confidence level of content auditing is obtained finally by filter result, if confidence level
Value is less than preset threshold value, determines that auditing result is legal；If confidence value is more than or equal to preset threshold value, determines and examine
Core result is illegal.
Step S612 determines that auditing result is illegal；Execute step S614.
Step S614 carries out signature processing to above-mentioned auditing result, the auditing result after being signed.
The signature is usually CA (Certificate Authority, digital certificate service organization) certificate signature, with statement
Or guarantee the correctness of the auditing result.
Auditing result after above-mentioned signature is determined as endorsement as a result, the endorsement result is back to client by step S616
End.The endorsement result generally includes auditing result and CA signing certificate.
After client receives the endorsement result of all endorsement nodes, the whether correct, comparison by the signature of verifying endorsement
Whether the endorsement result of all endorsement nodes is correct and checks whether the endorsement result for having received all endorsement nodes.
Transaction endorsement method in above-mentioned block chain passes through the intelligence on block chain after endorsement node receives transaction motion
Whether energy contract calls preset content auditing algorithm, and judged by the content auditing algorithm to include default in cochain content
Sensitive word；If calling third party's service audit to cochain content to not include sensitive word in cochain content, if audit is logical
It crosses and determines that auditing result is legal；If determining that auditing result is legal to include sensitive word in cochain content；Finally audit is tied
Fruit carries out signature processing, obtains endorsement result.Which, which treats cochain content and carries out secondary audit, can guarantee auditing result
Correctness, and content auditing algorithm is completed on endorsement node, entire auditing flow is open and clear, and has centainly controllable
Property.
The embodiment of the present invention also provides the transaction endorsement method in another block chain, and this method is applied in block chain
Client, as shown in fig. 7, this method comprises the following steps:
Step S702 waits for that cochain content generates transaction motion according to this if received to cochain content；Wherein, the friendship
It include to cochain content in easy motion.
It is above-mentioned to the cochain content text that be usually content providers uploaded in the client by register account number, picture or
Person's video etc..Above-mentioned transaction motion not only includes also typically including subscriber identity information, Transaction Information etc. to cochain content.
Above-mentioned transaction motion is sent to the endorsement node in endorsement strategy included by step S704, to pass through endorsement node
Simulation executes the intelligent contract on block chain, to audit to cochain content, obtains auditing result；It is generated and is endorsed according to auditing result
As a result.
In specific implementation, it is interacted by the SDK of client and block chain network, the intelligence on block chain can be called
Energy contract, and according to the node of verifying demand selected part audit side as endorsement node, so as to generate corresponding endorsement
Strategy.
Transaction endorsement method in above-mentioned block chain waits for that cochain content is raw according to this if received after cochain content
At transaction motion；The transaction motion is sent to the endorsement node in endorsement strategy included again, to hold by endorsement node simulation
Intelligent contract on row block chain obtains auditing result to audit to cochain content；Endorsement result is generated according to auditing result.
The intelligent contract which is endorsed on node by block chain is audited to cochain content, not by the control of any individual or entity,
Thus the auditing flow is open and clear, auditing result is avoided by interference caused by subjective factors, to improve block chain cochain content

Judging result, at this point, endorsement node the judging result for treating cochain content is signed, endorsed as a result, finally will
Endorsement result is sent to the block platform chain of content providers.
After all endorsement nodes have all sent endorsement result in endorsement strategy, whether block platform chain owns judgement
The endorsement result of endorsement node is legal (being equivalent to endorsement to pass through), if it is not, failing to cochain content cochain；If
It is legal, then it will carry out being packaged one transaction of composition to cochain content, and be sent to common recognition node after signing to the transaction, altogether
Know node cochain content treated according to current common recognition algorithm and be ranked up, and according to block generation strategy generate after sorting to upper
The block is committed to Committer node (alternatively referred to as submission node) by the corresponding block of chain content.Above-mentioned block generates plan
Slightly usually can according to cochain content type or data format etc. divide block.
After Committer node receives block, the transaction motion that can be submitted to content providers in block is verified,
It is to call VSCC (validator system chaincode, proving program system chain code) conduct relevant to the transaction
A part of transaction verification process determines the validity of transaction, and indicate within a block which transaction be it is effective which be nothing
Effect, so that content providers listen to invalid transaction and effective transaction.If verification failure (that is to say that transaction is invalid
), then the transaction motion of content providers is invalid.If being proved to be successful and (that is to say that transaction is effective), block is appended to
On alliance's block chain, by broadcasting to cochain content to all nodes in alliance's block chain for content providers, alliance's block is written
Catenary system, and modify world state.
