Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a block chain voucher issuing and depositing method based on network data interaction according to an embodiment of the present invention, and fig. 2 is a schematic structural diagram of a block chain voucher issuing and depositing system based on network data interaction according to an embodiment of the present invention, as shown in fig. 1, the method includes:
and step S01, obtaining the node quantization index of the application node according to the storage information of the data interaction of the application node.
The block chain-based certificate issuing and storing system of the embodiment of the invention mainly comprises: the system comprises a block chain certificate storing and distributing server, a service background for short, at least one block chain and application nodes corresponding to user accounts of the block chains. As shown in fig. 2, the service background is connected to the blockchain 1 and the blockchain 2, and the service background is connected to the n application nodes. Each application node can establish a corresponding user account in each block chain according to actual needs.
The service background monitors each application node, processes the business logic of data interaction of the application nodes, and stores and traces the key information on the block chain. Taking the intellectual property system as an example, the data interaction mainly refers to the authorization or transfer transaction event of the patent right.
And the service background calculates a Proof of Value (POV) and a node quantization index of an active program for representing each application node in a certificate issuing and storing system according to the recorded storage information of the data interaction of the application nodes.
Each application node can be registered and set in each block chain according to actual needs, so that a user account corresponding to the application node in the block chain is created, and an account address is allocated. The user account is a digital key and an address for determining ownership, and plays a role in managing private keys, addresses and blockchain data.
Because the account creation of the user is a time-consuming process, the certificate issuing and storing system can generate accounts in batches in advance, and when the user registers, unused accounts are automatically selected for binding. The previously generated empty account is a blockchain account, which is essentially a pair of public and private keys, the public key generating an account address, and the private key being accessible. Then the system binds with the private key when registering the user, which is equivalent to the account assigned with the block chain. The private key exists, namely a json format keystore file, and is stored on the service background when being generated in batches.
And step S02, if the application node meets the preset trigger condition for issuing the pass certificate, calling a pass certificate contract to the block chain corresponding to the trigger condition for issuing the pass certificate.
The basic characteristics of the application certificate passing issued by the block chain can be preset according to actual needs by the certificate passing issuing and storing system, and the basic characteristics comprise: name, identification, amount issued, credential issuance trigger, etc., and writes these base characteristics to the credential contract. The permit is deployed onto the blockchain at the beginning of the building and running of the blockchain. The block chain may be a federation chain. As shown in fig. 2, the blockchain 1 and the blockchain 2 respectively store corresponding certification contracts.
The specific deployment process can be performed by calling an interface through an administrator account, and a certain bottom-layer certificate needs to be consumed during the period: such as bitcoin, etherhouse, EOS, etc. Parameters of the deployment interface are a block chain server address URL, an account name and an account password, and the interface returns a contract address for use in subsequently calling a contract.
The service background stores the corresponding certificate issuing triggering conditions of each block chain for triggering certificate issuing. Whether the application nodes meet preset pass certificate issuing triggering conditions or not is judged through monitoring of the application nodes, and the pass certificate issuing triggering conditions can be set to be various issuing types according to actual needs of the block chains. And if any application node meets any preset certification-passing issuing triggering condition, calling the stored certification-passing contract from the corresponding block chain.
Step S03, according to the triggering condition of the certificate issuing and the node quantization index of the application node, obtaining the number of certificates issued by calculation through a certificate issuing algorithm in the certificate issuing contract, and indicating the block chain to send the certificates issued to the user account corresponding to the application node according to the number of the certificates issued.
And the service background calculates the pass number T of the application pass issued this time through a pass issuing algorithm in the pass contract. Wherein the passport issuance algorithm may be expressed as follows:
T＝F(C,V)；
as can be seen, the number T of issued passes depends on the pass issuing trigger condition C currently satisfied by the application node and the node quantization index V corresponding to the application node.
And the service background sends a certification issuing request to the corresponding block chain, so that the block chain issues application certification of a certification amount T to the user account corresponding to the application node, the issuing of the certification is closely related to the value certification and the activity degree of the user account in a certification issuing and storing system, and the certification is not acquired by dishonest evidence acquiring means such as long-term startup or repeated bill swiping.
According to the embodiment of the invention, the node quantization indexes of each application node are obtained through the storage information of data interaction, and when the application nodes meet the triggering condition of issuing the certificates, the application certificates are sent to the application nodes according to the number of the certificates obtained by calculating the node quantization indexes, so that the certificate issuing distribution mechanism is more open and scientific, the high energy consumption waste of a block chain system is avoided, and the good digital economic system ecology is favorably constructed.
Fig. 3 is a flowchart of another block chaining ticket issuing and saving method based on network data interaction according to an embodiment of the present invention, and as shown in fig. 3, the step S01 specifically includes:
step S011, obtaining the label quantization indexes of the application nodes corresponding to the labels through a preset quantization index algorithm according to the storage information of the data interaction of the application nodes and the labels corresponding to the storage information of the data interaction.
When data interaction occurs among the application nodes, the service background performs data preprocessing on data content contained in the data interaction to obtain at least one label corresponding to the data content, and stores the label in the storage information, so as to obtain the label corresponding to the storage information of the data interaction.
And obtaining a relation matrix corresponding to the label according to the storage information of the data interaction containing the same label and the output and receiving relation in the data interaction process. For example, the storage information of the data interaction is that, when the application node a sends a certain data content to the application node B, the application node a is an output side of a label corresponding to the certain data content, and the application node B is a receiving side of the label corresponding to the certain data content. Taking intellectual property as an example, the application node a authorizes or transfers the patent D to the application node B, and the data preprocessing on the content of the patent D can obtain the corresponding label 1 and label 2 corresponding to the patent D, so that the application node a is the output side of the label 1 and label 2, and the application node B is the receiving side of the label 1 and label 2.
And then, obtaining the label quantization indexes of the application nodes corresponding to the labels according to a preset quantization index algorithm, and obtaining the quantization ranking of the application nodes under the labels according to the size of the indexes, wherein the higher the ranking is, the more active the application node corresponding to the label is.
Further, before the step S011, the block chain voucher issuing and saving method based on network data interaction further includes:
and S010, performing preset natural language processing on the data content of the data interaction storage information to obtain the labels with the preset label quantity corresponding to the data interaction storage information.
There are many methods that can be used to pre-process data content, and natural language processing is merely exemplified here. The data content is analyzed by natural language, and keywords are extracted as tags. The specific extraction mode may be obtained by constructing different extraction models according to different fields and performing training, or may be obtained by using a keyword ranking algorithm in natural language processing, and obtaining a preset number of top-ranked keywords, for example, 5 keywords, as tags corresponding to the data content, which is not specifically limited herein.
And step S012, obtaining the node quantization index of each application node according to the label quantization index.
The node quantization index of the application node is obtained by further analyzing the label quantization indexes corresponding to the labels under the application node, for example, the node quantization index of the application node can be obtained by performing weighted average on a plurality of label quantization indexes with the highest numerical values, and the node quantization index can be specifically set according to actual needs.
According to the embodiment of the invention, the label quantization indexes corresponding to the labels are obtained through the labels corresponding to the data interaction storage information which are obtained in advance, and then the node quantization indexes of the application nodes are further obtained, so that the node quantization indexes can be more scientifically and reasonably obtained and used for evidence-based distribution.
Fig. 4 is a flowchart of a block chaining ticket issuing and saving method based on network data interaction according to another embodiment of the present invention, and as shown in fig. 4, the step S01 specifically includes:
step S013, according to the data interaction storage information of each application node and the labels corresponding to the data interaction storage information, calculating the label contribution index and the label demand index of each application node corresponding to the labels through a preset contribution index algorithm and a preset demand index algorithm; the label contribution index is used for representing the index of the application node as a data interaction output party, and the label demand index is used for representing the index of the application node as a data interaction receiving party.
According to the output and receiving relation of data interaction, an output party of the data interaction is considered to contribute to the corresponding landmark, and a receiving party of the data interaction is considered to form a demand for the corresponding landmark, so that when the quantitative index of the label is calculated, the label contribution index for representing the contribution degree of the application node to the label and the label demand index for representing the application node to a label demand program can be calculated according to a contribution index algorithm and a demand index algorithm respectively.
The contribution index algorithm and the demand index algorithm can be set according to actual needs, such as a method for establishing a service index library and a service searching method based on a social network, and the invention patent number is as follows: CN104182483A, a service sequencing and recommending method and system based on social network interaction data, patent number: CN 104199843A. Only one of which is given here by way of example:
applying label contribution index of node i
Label demand index for application node i
Wherein, δ is a preset damping coefficient, which represents the probability of the application node i sending to the application node j, the value is between 0 and 1, and can be set according to the network characteristics of different block chains, cjThe number of objects externally connected by the application node j in the block chain, and the number of application nodes potentially capable of being used as a receiver when the application node j is used as a data interaction output party, cj' is the number of objects connected by the application node j in the blockchain, and is also the number of potential application nodes that can be used as output sides when the application node j is used as a receiving side.
And step S014, obtaining a node quantization index of each application node according to the label contribution index and/or the label demand index.
And obtaining the node quantization index of each application node according to the obtained label contribution index and label demand index. Specifically, the node quantization index may directly adopt a tag contribution index or a tag demand index, or may be obtained by performing weighted summation or the like on the tag demand index of the tag contribution index, and may be set according to actual needs.
According to the embodiment of the invention, the label contribution index and the label demand index are respectively obtained according to the output and receiving relation in data interaction, and then the node quantization index is further obtained, so that the active program of the application node can be more accurately analyzed, and the more scientific and reasonable node quantization index is obtained and is used for calculating the number of the certificates.
Fig. 5 is a schematic structural diagram of another block chain voucher issuing and depositing system based on network data interaction according to an embodiment of the present invention, and based on the above embodiment, the block chain voucher issuing and depositing method based on network data interaction further includes:
step S04, if the preset certificate storing triggering condition is judged to be met, a certificate storing request is sent to the block chain; wherein the certificate storing request comprises certificate storing data;
and step S05, the block chain stores the chain of the evidence storage data.
The block chain is also pre-deployed with a certificate-storing contract for performing uplink storage on key certificate-storing data on the block chain so as to ensure that all certificate-storing data are stored in a distributed manner on the block chain, and the integrity and the effectiveness of the certificate-storing data are ensured through an asymmetric encryption and signature mechanism. For example, for an intellectual property system, including a patent authorization or transfer transaction event: content of patent rights, parties to the transaction, price of the transaction, time of the transaction, etc.
The evidence storage data covers the related data for calculating the node quantization index, ensures that each piece of related data can be traced, ensures the authenticity and integrity of the data, and technically ensures that the quantization calculation process has the trust characteristic of going to the center.
The specific certificate storage triggering is judged by the service background according to a preset certificate storage triggering condition, and if the judgment meets the certificate storage triggering condition, a certificate storage request is sent to the block chain. And the block chain calls a storage contract and stores the chain storage data in the storage request.
Further, the step S04 specifically includes:
and S041, if the preset certificate storage triggering condition is met, uploading the certificate storage data needing certificate storage to a distributed storage system to obtain a file identifier corresponding to the certificate storage data.
Step S042, sending a certificate storing request to the block chain; wherein the certificate storing request comprises the file identification.
Since the process of performing uplink storage by the blockchain needs to consume the bottom layer certificate and the storage space of the blockchain is limited, in order to save the consumption of the bottom layer certificate and the storage space of the blockchain, for the storage data including the large certificate storing file, the service background may store the certificate storing file to the distributed storage system IPFS shown in fig. 5, and obtain a file identifier corresponding to the certificate storing file, for example, a Hash value, so that the corresponding certificate storing file may be obtained from the distributed storage system according to the file identifier.
At this time, the certificate storing request sent by the service background to the block chain may include the file identifier and characteristic information of the certificate storing file, such as an author, a unit, and publication time of the file.
A specific example of the credentialing process is given below:
1. and deploying the storage and verification contract on the block chain, returning a storage and verification contract address, and deploying and storing the storage and verification contract on the block chain at the beginning of system operation, wherein the storage and verification contract address is the same as the verification contract.
2. The front-end application (e.g., WeChat, APP, browser, etc.) uses the HTML form to collect the relevant information of the certified file entered by the user, such as the file name, file description, file picture, file, etc. Different corresponding related information of different certificate issuing and storing systems. For intellectual property rights such as patents, it shall be the name of the patent, the applicant, the publication number, the classification number, the text of the patent.
3. And the service background uploads the certificate storage file to the IPFS.
4. And receiving a link Hash value corresponding to the returned uploaded content, and storing the link Hash value in a service background.
5. And the service background calls a verification contract through the verification contract address to store the characteristic information of the file and the Hash value which is returned by the IPFS and corresponds to the verification file into the block chain.
6. The service background monitors the block chain event, after the deposit certificate contract successfully stores the deposit certificate into the block chain, an event is triggered, and all relevant information of the deposit certificate can be acquired in the event callback.
7. When the event is triggered, the service background reads the event content and stores the related information into the database of the background service.
8. When a user inquires through the front-end application, the service background reads data and assembles the data according to a certain format.

According to the embodiment of the invention, the key data needing to be certified is subjected to uplink storage on the block chain through the pre-deployed certification contract, so that the integrity, reliability and traceability of the key data are ensured.
Fig. 6 is a schematic structural diagram of a block chaining credential issuing and depositing device for network data interaction according to an embodiment of the present invention, and as shown in fig. 6, the device includes: the system comprises an index calculation module 10, a certificate approval triggering module 11 and a certificate approval calculation module 12; wherein the content of the first and second substances,
the index calculation module 10 is configured to obtain a node quantization index of an application node according to storage information of data interaction of the application node; the certification passing triggering module 11 is configured to, if the application node meets a preset certification passing issuance triggering condition, invoke a certification passing contract to a block chain corresponding to the certification passing issuance triggering condition; the voucher calculation module 12 is configured to calculate, according to the voucher issuance trigger condition and the node quantization index of the application node, a voucher amount through a voucher issuance algorithm in the voucher contract, and instruct the block chain to send a voucher to the user account corresponding to the application node according to the voucher amount.
The index calculation module 10 monitors each application node, processes the service logic of data interaction between the application nodes, and stores and traces the key information on the block chain.
The index calculation module 10 calculates a node quantization index for representing the value proof and the active program of each application node in the certificate issuing and storing system according to the recorded storage information of the data interaction of the application nodes, and sends the node quantization index to the certificate issuing and storing system 12.
Each application node can be registered and set in each block chain according to actual needs, so that a user account corresponding to the application node in the block chain is created, and an account address is allocated. The user account is a digital key and an address for determining ownership, and plays a role in managing private keys, addresses and blockchain data.
Because the account creation of the user is a time-consuming process, the certificate issuing and storing system can generate accounts in batches in advance, and when the user registers, unused accounts are automatically selected for binding. The previously generated empty account is a blockchain account, which is essentially a pair of public and private keys, the public key generating an account address, and the private key being accessible. Then the system binds with the private key when registering the user, which is equivalent to the account assigned with the block chain. The existing private key is a json format keystore file, and is stored in the certification-related triggering module 11 when being generated in batches.
The basic characteristics of the application certificate passing issued by the block chain can be preset according to actual needs by the certificate passing issuing and storing system, and the basic characteristics comprise: name, identification, amount issued, credential issuance trigger, etc., and writes these base characteristics to the credential contract. The permit is deployed onto the blockchain at the beginning of the building and running of the blockchain.
The pass-certificate triggering module 11 stores pass-certificate issuing triggering conditions corresponding to each block chain for triggering pass-certificate issuing, and determines whether the application node meets preset pass-certificate issuing triggering conditions or not by monitoring each application node, wherein the pass-certificate issuing triggering conditions can be set to various issuing types according to actual needs. If any application node meets any preset certification-based issuing triggering condition, the certification-based triggering module 11 calls the stored certification-based contract from the corresponding block chain and sends the contract to the certification-based calculating module 12.
The certification passing calculation module 12 calculates the certification passing amount T of the application certification passing issued this time through a certification passing issuing algorithm in the certification passing contract. Wherein the passport issuance algorithm may be expressed as follows:
T＝F(C,V)；
as can be seen, the number T of issued passes depends on the pass issuing trigger condition C currently satisfied by the application node 12 and the node quantization index V corresponding to the application node 12.
The evidence-passing calculation module 12 sends a evidence-passing issuing request to the corresponding block chain, so that the block chain issues application evidence of corresponding evidence-passing quantity T to the user account corresponding to the application node, the issuing of the evidence-passing is closely related to the value proof and the activity degree of the user account in the evidence-passing issuing and storing system, and dishonest evidence-obtaining means such as long-term startup or repeated bill-swiping are not required.

And obtaining a relation matrix corresponding to the label according to the storage information of the data interaction containing the same label and the output and receiving relation in the data interaction process. For example, the storage information of the data interaction is that, when the application node a sends a certain data content to the application node B, the application node a is an output side of a label corresponding to the certain data content, and the application node B is a receiving side of the label corresponding to the certain data content.
And then, obtaining the label quantization indexes of the application nodes corresponding to the labels according to a preset quantization index algorithm, and obtaining the quantization ranking of the application nodes under the labels according to the size of the indexes, wherein the higher the ranking is, the more active the application node corresponding to the label is.
Further, the index calculation module is further configured to:
and obtaining the labels with the number of the preset labels corresponding to the data interaction storage information by carrying out preset natural language processing on the data content of the data interaction storage information.
There are many methods that can be used to pre-process data content, and natural language processing is merely exemplified here.

The specific extraction mode may be obtained by constructing different extraction models according to different fields and performing training, or may be obtained by using a keyword ranking algorithm in natural language processing, and obtaining a preset number of top-ranked keywords, for example, 5 keywords, as tags corresponding to the data content, which is not specifically limited herein.
The node quantization index of the application node is obtained by further analyzing the label quantization indexes corresponding to the labels under the application node, for example, the node quantization index of the application node can be obtained by performing weighted average on a plurality of label quantization indexes with the highest numerical values, and the node quantization index can be specifically set according to actual needs.
The apparatus provided in the embodiment of the present invention is configured to execute the method, and the functions of the apparatus refer to the method embodiment specifically, and detailed method flows thereof are not described herein again.
According to the embodiment of the invention, the label quantization indexes corresponding to the labels are obtained through the labels corresponding to the data interaction storage information which are obtained in advance, and then the node quantization indexes of the application nodes are further obtained, so that the node quantization indexes can be more scientifically and reasonably obtained and used for evidence-based distribution.
