Networking data library technology.Its main feature is that it is decentralization, open and clear, allow each user to each may participate in maintenance data-base recording.Area
Block chain network is the new application mould of the computer technologies such as Distributed Storage, point-to-point transmission, common recognition mechanism, Encryption Algorithm
Formula.Block chain network mainly includes data Layer, intelligent contract layer etc., wherein data Layer encapsulates bottom data block and phase
The basic datas such as the data encryption of pass and timestamp and rudimentary algorithm, and bottom data block is presented with chain structure, i.e. block
Chain is a kind of a kind of linked data structure for being sequentially in time combined into data block in such a way that sequence is connected, and with close
The distributed account book that can not be distorted He can not forge that code mode guarantees.
This step introduces block chain network, and intellectual property authority organ's node is any end of State Intellectual Property Office's authorization
End, this endpoint to register is in block chain network, as a node in block chain network.This step uses block chain technology energy
Realize that the distributed recording and distributed storage of intellectual property data, so-called distributed recording can exactly be weighed by intellectual property
Prestige organ nodes records intellectual property data generates intellectual property block, and carries out cochain, intellectual property in block chain network
Data are not recorded by the mechanism of a centralization.So-called distributed storage is that data can store in all participations maintenance
In the node of data, rather than it is centrally stored in the agency node of centralization.
The intellectual property data of this step includes patent data, such as the applying date, application number, publication date, publication number, proprietary term
Title, Main classification number, applicant, inventor, agency etc.；Branding data, such as the applying date, application number, message serial number, application
People, trade mark registration number etc..The unique number of intellectual property can be the intellectual properties such as application number, grant number or trade mark registration number
Unique identification.
In one embodiment, step S1, comprising:
Step S101 is inquired and is read data: being searched from own database according to unique number corresponding with unique number
Intellectual property data return to miscue to requesting party if not finding, if finding, it is corresponding to read unique number
Intellectual property data, include statutory status in intellectual property data.
Intellectual property authority organ node is stored with all to State Intellectual Property Office's application in own database
Intellectual property data, and this intellectual property data is according to the data synchronization updating with intellectual property data library, to guarantee knowledge
Property right data are latest datas.It is intellectual property data library that own database, which can also be defined,.
Intellectual property authority organ's node is searched by unique number and obtains intellectual property data, when not finding data
When, it is believed that the unique number mistake of requesting party's input returns to miscue to requesting party, please again defeated such as unique number mistake
The prompt such as enter.Intellectual property authority organ node can obtain unique volume of intellectual property owner input by interactive interface
Number, this miscue is returned to by interactive interface, and intellectual property owner is waited to input unique number again.
Step S102, judges statutory status: whether the statutory status in judgemental knowledge property right data is licensing status, if
Unauthorized state, then to requesting party return it is unauthorized can not cochain prompt if licensing status then unique number and knowledge are produced
Flexible strategy are according to generation intellectual property block.
The statutory status of intellectual property generally comprises application status, open state, substantive examination state, bulletin state and authorization shape
State etc..Usually the intellectual property with licensing status is just easy to produce IP dispute situation, therefore this step is known in generation
Before knowing property right block, intellectual property authority organ node also judge will the intellectual property of cochain whether be in licensing status, guarantor
The corresponding intellectual property data of intellectual property block that demonstrate,proving will generate is the intellectual property having the right.
Step S103 compares unique number: by all unique numbers in unique number and preset block chain list into
Row compares, and when not having unique number in block chain list, then unique number and intellectual property data is generated intellectual property area
Block.
All nodes in block chain network are preset with a block chain list, include block chain in block chain list
In the corresponding unique number of each block of cochain, intellectual property data and cryptographic Hash.Any node generates in block chain network
After block and broadcast, other blocks update the block chain list of itself, in order to complete the synchronization of data.
In order to guarantee the uniqueness for the intellectual property data that will be generated, avoid identical intellectual property data it is multiple on
Chain, after guaranteeing that intellectual property data is the intellectual property having the right, intellectual property authority organ node also by unique number with
Whether all unique numbers in block chain list compare, judge the intellectual property data obtained cochain.When block chain
When there is no unique number in list, it is believed that this intellectual property data also not by cochain, intellectual property authority organ node continue into
Row generates intellectual property block step.
Judgemental knowledge property right data: step S104 when having contained unique number in block chain list, continues judgemental knowledge
Whether property right data intellectual property data corresponding with unique number in block chain list is identical, if they are the same, then returns to knowledge production
The prompt of Data duplication cochain is weighed, if it is different, unique number and intellectual property data are then generated intellectual property block.
When having contained unique number in block chain list, it is believed that this intellectual property data cochain.But due to there is also
The same unique number, intellectual property data have situations such as update, therefore also continue judging the intellectual property data of cochain
Whether the intellectual property data obtained with intellectual property authority organ's node is identical, such as identical, then it represents that be identical intellectual property
Data, in order to avoid repeating cochain, intellectual property authority organ node is to intellectual property data without cochain.If it is different, then
Intellectual property data is thought there are update status, this intellectual property data is not to repeat cochain, intellectual property authority organ section
Point continues to generate intellectual property block step.
The judgement that the present embodiment passes through statutory status in the lookup of unique number and intellectual property data, it is ensured that will generate
Intellectual property block be to have applied in the intellectual property of state of having the right.By by unique number and intellectual property data with
Block chain list is compared, and avoids the repetition cochain for repeating block, guarantees the uniqueness of intellectual property block.
In one embodiment, in step S1, unique number and intellectual property data are generated into intellectual property block, packet
It includes:
Creation of knowledge property right block: step S111 includes block head and block body in intellectual property block, wraps in block head
Cryptographic Hash variable, timestamp variable, the unique number variable of cryptographic Hash variable, current block containing previous block, in block body
Include intellectual property data variable.
In creation of knowledge property right block, intellectual property authority organ's node passes through in preset Blockchain class
New_block method is created.When creating new block by Blockchain class, if intellectual property authority organ node
Primary creation block, then also create an empty block chain list, for storing the information of the block of cochain.If intellectual property
Authoritative organ's node has contained block chain list, then without creating empty block chain list.
Assignment: intellectual property data is carried out abstract by cryptographic hash algorithm and handles to obtain abstract word by step S112
Current time is assigned to timestamp variable, by unique number by abstract character assignment to the cryptographic Hash variable of current block by symbol
It is assigned to unique number variable, intellectual property data is assigned to intellectual property data variable.
Cryptographic hash algorithm is the very basic also very important technology of information technology field, it can be by random length
Binary value (plaintext) is mapped as the binary value (hash value) of shorter regular length, and different plaintexts is difficult to be mapped as
Identical hash value.Common cryptographic hash algorithm includes MD4 (Message Digest eap-message digest), (MD4's changes MD5
Into version), SHA-1 etc..Abstract character is generated calculating using cryptographic hash algorithm intellectual property data, can guarantee that knowledge produces
The integrality of flexible strategy evidence.Current time is assigned to timestamp variable by this step, as time evidence, it is ensured that intellectual property data
It is true and reliable.Unique number is also carried out assignment by this step, corresponding as the lookup that can be convenient subsequently through unique number
Intellectual property block.
Before the character assignment that will make a summary is to the cryptographic Hash variable of current block, intellectual property authority organ node can also be incited somebody to action
Abstract character is signed, and by the abstract character assignment after signature to the cryptographic Hash variable of current block, signature, which can determine, to be known
Know the node identities of property right block generation side.
Step S113 generates intellectual property block: the cryptographic Hash of last-of-chain block is obtained from preset block chain list, it will
The cryptographic Hash of last-of-chain block is assigned to the cryptographic Hash variable of previous block, generates an intellectual property block.
The characteristics of due to block chain network, each block must include the cryptographic Hash of previous block, therefore this step is from certainly
Cryptographic Hash of the cryptographic Hash of last-of-chain block as previous block is obtained in the block chain list of body node.Wherein, last-of-chain block is
The newest block being added into block chain network.
The present embodiment is relied on by the new_block method creation of knowledge property right block in preset Blockchain class
It the timestamp of block chain network and the characteristics such as can not distort, ensure that the intellectual property block of creation can not be tampered, as rear
Continuous evidence uses.
Step S2, broadcast intellectual property block: intellectual property authority organ's node broadcasts intellectual property block to block
Other nodes in chain network, intellectual property block complete cochain in block chain network, form new block chain.
In order to guarantee that the integrality and consistency of each node data in block chain network, this step are generating intellectual property area
It after block, is also broadcasted, for the synchronous intellectual property data of other nodes.
In one embodiment, step S2, comprising:
Step S201, broadcast: intellectual property authority organ's node by the corresponding unique number of intellectual property block, abstract word
Symbol and intellectual property data are added in block chain list after the cryptographic Hash of previous block, and the intellectual property block of generation is determined
Justice is last-of-chain block, and intellectual property block is broadcasted to other nodes into block chain network.
Intellectual property authority organ node before being broadcast, is also updated itself block chain list, guarantees that itself is counted
According to integrality.When broadcasting, starting common recognition orderer node is saved intellectual property authority organ node by orderer
Point establishes connection with multiple peer-to-peer network peer nodes, and intellectual property block is broadcasted to peer node, and by intellectual property area
Block is stored in peer node.
Step S202, it is synchronous: other nodes read unique number in intellectual property block, the cryptographic Hash of previous block,
After the cryptographic Hash and intellectual property data of current block, unique number, the cryptographic Hash of current block and intellectual property data are added
It is added to after the cryptographic Hash of previous block described in block chain list, the intellectual property block of generation is defined as last-of-chain block,
The cochain for completing intellectual property block, forms new block chain.
Other nodes in block chain network can receive the intellectual property comprising intellectual property data by peer node
Block.The cryptographic Hash of unique number, current block in intellectual property block and intellectual property data are updated to by other nodes
In itself block chain list, it is synchronous to complete data.
For the present embodiment after generating intellectual property block, the broadcast of also progress block is synchronous with data, ensure that block
The data integrity and consistency of all nodes in chain network.
Step S3, generate transaction block: intellectual property transaction node obtains the Transaction Information that intellectual property owner sends
Cochain is requested, and includes Transaction Information and unique number in the request of Transaction Information cochain, and intellectual property transaction node believes transaction
Breath generates transaction block, will be on the block chain where trading post block chaining to unique number.
Intellectual property transaction node in this step can be it is multiple, register and have in transaction in block chain network
The terminal of chain right is intellectual property transaction node.Transaction Information include obligee's information, assignee's information, trade contract,
Number of deals etc., trade contract can be by including ordinary license, Exclusive License, compulsory licensing, transfer etc..Intellectual property transaction node
The Transaction Information of intellectual property owner input can be obtained by interactive interface.
In one embodiment, in step S3, intellectual property transaction node obtains the transaction that intellectual property owner sends
Information cochain is requested, and includes Transaction Information and unique number in the request of Transaction Information cochain, and intellectual property transaction node will be handed over
Easy information generates transaction block, comprising:
Step S301 judges Transaction Information: obtaining the Transaction Information cochain request that intellectual property owner sends, transaction letter
Include Transaction Information and unique number in breath cochain request, judgemental knowledge property right owner and obligee in Transaction Information or
Whether assignee is identical, if it is different, then returning to miscue to requesting party.
Before Transaction Information is generated transaction block by intellectual property transaction node, judgemental knowledge property right owner and Transaction Information
In obligee's information or assignee's information it is whether consistent, if inconsistent, by interactive interface to requesting party return mistake mention
Show, such as obligee or the prompt of assignee's illegal request avoid other staff to guarantee that transaction is the request of relationship severity person
Cochain after playing tricks to Transaction Information.
Judgemental knowledge property right data: step S302 if they are the same, is then obtained in preset block chain list by unique number
The corresponding intellectual property data of last-of-chain block judges whether is obligee in the obligee and intellectual property data in Transaction Information
It is identical, if it is different, then returning to miscue to requesting party, if they are the same, then Transaction Information is generated into transaction block.
Other than judging the consistency of above-mentioned Transaction Information, intellectual property transaction node also passes through unique number and obtains last-of-chain
Intellectual property data in block, judge obligee in Transaction Information whether with the Rights owners one in intellectual property data
It causes, in order to guarantee that obligee is the owner of intellectual property.If searched by unique number less than last-of-chain block, it is believed that this
Unique number then also returns to miscue to requesting party without corresponding intellectual property data, such as the non-cochain of intellectual property data, hands over
Easy information can not the prompt such as cochain.
The present embodiment is by way of judging Transaction Information, it is ensured that transaction cochain request is the request of interest-related persons,
Pass through judgemental knowledge property right data, it is ensured that the obligee that will be generated in the Transaction Information of transaction block is possessing for intellectual property
Person.
In one embodiment, in step S3, the Transaction Information is generated transaction block by intellectual property transaction node, will
On block chain where trading post block chaining to unique number, comprising:
Step S311 creates transaction block, includes block head and block body in block of trading, includes previous area in block head
The cryptographic Hash variable of block, the cryptographic Hash variable of current block, timestamp variable include Transaction Information variable in block body.
The step of this step is with creation of knowledge property right block is similar, since transaction block should all be based on the knowledge of cochain
Property right block, therefore when creation transaction block, without creating unique number variable.Creation trade block when, intellectual property
Transaction node is created by the new_block method in preset Blockchain class.
Step S312, assignment: carrying out abstract by cryptographic hash algorithm for Transaction Information and handle to obtain abstract character, will
Character assignment make a summary to the cryptographic Hash variable of current block, current time is assigned to timestamp variable, by Transaction Information assignment
Give Transaction Information variable.
Before the character assignment that will make a summary is to the cryptographic Hash variable of current block, intellectual property transaction node can also will make a summary
Character is signed, and by the abstract character assignment after signature to the cryptographic Hash variable of current block, signature can determine trading post
The node identities of block generation side.
Step S313, generates transaction block: the corresponding last-of-chain block of unique number is obtained from preset block chain list
