Detailed Description
With the increasing popularity of the internet, more and more users choose to disclose their own creative works on the internet. The original works of the users usually need to be approved by a work auditor before being published in the internet.
The original review specifically refers to a process in which a work auditor arranges professionals to audit the work uploaded by a user through a special auditing method (for example, a retrieval comparison method). After the original audit is passed, the works uploaded by the user can be regarded as original works; otherwise, the work is considered to be possibly involved in plagiarism.
In the related art, when a product auditor performs original audit on a product uploaded by a user, a special auditor (or a team) is usually arranged to perform original audit operation. The reviewer will typically first read the user's work and determine a number of keywords. Then, the auditor searches the database for the works carrying the keywords based on the keywords. After finding the works, the auditor compares the searched works with the works uploaded by the user. If the expression mode and the expression meaning of the works uploaded by the users and the retrieved works are almost the same, the works uploaded by the users can be determined to be suspected of plagiarism. If the expression mode or the expression meaning of the work uploaded by the user is inconsistent with the expression mode or the expression meaning of the retrieved work, the work uploaded by the user can be determined to be the original work, and the original work is allowed to be uploaded to the internet.
As can be seen from the above process, in the related art, since a single work auditor usually performs the original audit when performing the original audit, the original audit may be centralized, so that the audit result is not objective, and even the error audit occurs.
Based on the method, the original auditing method of the works based on the block chain is provided. According to the method, a plurality of auditing nodes are selected in the block chain system, and the final auditing result is determined according to the auditing result of the to-be-audited work initiated by the user by each auditing node, so that the original auditing can be decentralized, and the error auditing caused by single auditing is avoided.
Specifically, the nodes in the blockchain system may interact with other node devices in the blockchain, and select a plurality of product review nodes. Then, after receiving the audit transaction initiated by the user, the nodes in the block chain system can respond to the transaction initiated by the user, distribute the works to be audited carried in the transaction to the audit nodes, and perform original audit on the works to be audited by the audit nodes. After each audit node submits the audit result, the nodes in the block chain system can also respond to the audit result submitted by each audit node and determine the final audit result aiming at the to-be-audited work based on the audit result returned by each audit node.
The technical solution proposed in the present application will be described below with reference to specific examples.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for checking originality of a work based on a blockchain according to the present application. As shown in fig. 1, the method includes:
s101, interacting with other node devices in the block chain, and selecting a plurality of product auditing nodes;
s102, responding to a transaction initiated by a user, distributing the to-be-audited works carried in the transaction to each auditing node, and performing original auditing on the to-be-audited works by each auditing node;
and S103, responding to the auditing results submitted by the auditing nodes, and determining the final auditing result aiming at the to-be-audited work based on the auditing results returned by the auditing nodes.
The block chain system may be a public chain (public block chain), a Private chain (Private block chain), a federation chain (Consortium block chain), or any combination thereof, which is constructed based on a server or a server cluster. The above-described blockchain system may include several nodes. The node can be a mobile phone, an IPAD and other terminal equipment.
The nodes may include audit nodes and non-audit nodes. And the auditing nodes are selected after the nodes included in the block chain system are mutually interacted through a preset election algorithm. When the original audit is performed on the works to be audited, the audit results uploaded by the audit nodes are usually referred to. The non-audit node can also perform original audit, but when the original audit is performed on the work to be audited, the audit result uploaded by the non-audit node is not usually referred to.
It should be noted that, under certain conditions, the audit node and the non-audit node may be converted into each other. For example, the audit condition of each node may be maintained in the block chain, and when the audit node often does not participate in the audit or the result of the audit is always inconsistent with the final audit result, it may be stated that the audit node "works" carelessly and needs to be converted into a non-audit node. After the audit node is converted into a non-audit node, the non-audit node which actively participates in audit and has the audit result always consistent with the final audit result in the non-audit node can be converted into the audit node.
When a user broadcasts a transaction (audit transaction) through a certain node, the nodes can perform original audit on works uploaded by the user respectively, and audit results are commonly identified to the block chain. After receiving the review result commonly identified by each review node, the node in the block chain may determine a final review result for the work to be reviewed based on the review result returned by each review node.
In an embodiment, when determining the final review result for the to-be-reviewed work based on the review result returned by each review node, a mechanism of few subject to majority may be adopted. Specifically, if the number of the audit nodes with the audit result of passing is greater than the number of the audit nodes with the audit result of failing, the final audit result of the to-be-audited work is determined as the audit passing; otherwise, the audit is determined to be not passed.
In another embodiment, when determining the final review result for the to-be-reviewed work based on the review result returned by each review node, an absolute threshold method may be adopted. Specifically, the number of the auditing nodes whose auditing results are passed may be counted, and the number may be compared with a preset threshold. If the number reaches the preset threshold value, determining that the final audit result aiming at the to-be-audited works is approved; otherwise, the audit is determined to be not passed. The preset threshold may be set by a developer based on experience; or calculated based on a neural network model.
According to the technical scheme, on one hand, the block chain has the memory content which is not tampered, so that the works uploaded by a user can be guaranteed not to be tampered when the works are subjected to original audit, and the authenticity of the works is guaranteed;
on the other hand, the final audit result of the to-be-audited work is made by referring to the audit results submitted by the selected audit nodes, so that the original audit can be decentralized, and the error audit caused by single audit is avoided.
The technical scheme described in the application is divided into three links of electing an audit node, performing original audit and replacing the audit node for detailed description.
Election auditing node
When a checking platform for original works is built based on a block chain, a plurality of checking nodes are usually selected from all nodes included in the block chain through a preset selection algorithm.
In one embodiment, the election algorithm may be an election algorithm based on a DPOS consensus mechanism.
The DPOS (deleted Proof of title) consensus mechanism is a consensus algorithm based on voting (refer to voting shareholders). Specifically, a statistical method may be used to determine, among the nodes included in the block chain, a number of nodes having the accounting right based on the voting result submitted by each node.
When selecting audit nodes based on the DPOS consensus mechanism, the original product audit platform builder (which may be a node in the block chain) may determine the number Q of audit nodes (usually, Q may be 21 or 101). After the number of the auditing nodes is determined, the building party can inform each node in the block chain to vote and collect the voting results of each node. After the building party obtains the voting summarization result, the votes obtained by the nodes can be sorted from top to bottom based on a mathematical statistic analysis method, and the node with the position of the top Q position is used as the auditing node.
After the audit nodes are elected, after the nodes in the block chain receive the transaction initiated by the user, the final audit result for the to-be-audited work can be determined based on the audit results submitted by each audit node.
In another embodiment, when selecting the review node, the original work review platform builder may sequence the review correctness rates corresponding to the node devices maintained in the block chain in order from large to small. Then, the construction party can select the first N nodes from the sorted nodes as the auditing nodes; the auditing correctness rate indicates the probability that the auditing result of a corresponding node for a certain work is consistent with the final auditing result of the work; the above N is a natural number.
The above-mentioned audit accuracy specifically refers to a probability that an audit result of a corresponding node for a certain work is consistent with a final audit result of the work.
In one case, each node in the block chain is generally a known or official auditing party who has participated in auditing the original works of the internet, and in the related art, the node generally has an examination on the auditing capability. At this time, when the auditing correctness corresponding to the node is determined, the checking capability assessment made on the node can be referred to the relevant field, and the auditing correctness of the node is calculated (if the auditing capability is strong, the auditing correctness is high), so that the probability that the auditing result made is consistent with the final auditing result of the product when the node is used for auditing the original product can be pre-judged.
For example, in the field of review of original works, related review units usually review the review capability of a reviewer, so that reviewers with poor review capability can be eliminated, and the high efficiency and the fairness of review teams are kept. At the moment, when the original work audit platform builder builds the platform, the auditor is used as a node, and the audit capability check result can be converted into the audit accuracy rate corresponding to the node through a mathematical method.
After the verification accuracy corresponding to each node is determined, the original work verification platform builder can sequence the verification accuracy corresponding to each node device maintained in the block chain according to the numerical value from large to small.
After the sorting is finished, the original work auditing platform builder can select the first N nodes from the sorted nodes as the auditing nodes; wherein N is a natural number.
For example, assume that 21 audit nodes are needed in a practical situation (i.e., N is 21). At this time, the original work auditing platform builder can select the first N nodes from the sorted nodes as the auditing nodes.
And at this moment, the selection of the auditing nodes in the block chain system is finished, and the establishment of the original work auditing platform is finished.
Secondly, performing original examination
When a user needs to upload works created by the user in the internet, the user can upload the works to be examined to the blockchain through an external account (an account pre-allocated to the user) and initiate a transaction.
In response to the transaction initiated by the user, the node corresponding to the external account can distribute the to-be-audited work carried in the transaction to each auditing node, and each auditing node performs original auditing on the to-be-audited work.
When the verification is implemented, the node corresponding to the external account can respond to the transaction initiated by the user, invoke the sending logic in the contract code of the original verification intelligent contract deployed in the block chain, and distribute the works to be verified carried in the transaction to each verification node.
In one case, the original audit intelligence contract may be created by an external account and stored in a block. At this time, when the intelligent contract is called, the nodes in the block chain can be directly called.
In another case, the original audit intelligence contract may be created by an external account and stored locally at the node. At this time, when the intelligent contract is called, the intelligent contract may be executed by calling a block header corresponding to the original audit intelligent contract in the block chain.
After the auditing nodes and the hands start the transaction initiated by the user, the original auditing of the works to be audited can be initiated.
Here, it should be noted that, in order to justify the original audit, before performing the original audit on each audit node, the audit sequence of each audit node generally needs to be randomly determined. After the audit sequence is determined, each audit node needs to return the audit result to the intelligent contract for storage according to the audit sequence.
In an embodiment, if any audit node does not return an audit result according to the randomly determined audit sequence, or does not return an audit result within a preset time period, it may be determined that the audit result of the audit node is a failure, and it may be considered that the audit node performs an audit operation "without scrutiny".
When the review node performs original review on the above-mentioned to-be-reviewed works, in an embodiment, a retrieval comparison method (not described in detail here) may be adopted. If the expression mode and the expression meaning of the works uploaded by the users and the retrieved works are almost the same, the works uploaded by the users can be determined to be suspected of plagiarism. If the expression mode or the expression meaning of the work uploaded by the user is inconsistent with the expression mode or the expression meaning of the retrieved work, the work uploaded by the user can be determined to be the original work, and the original work is allowed to be uploaded to the internet.
In an embodiment, in order to save the auditing workload of the auditing node (auditor), before the sending logic in the contract code of the original auditing intelligent contract deployed in the blockchain is called, the checking logic in the contract code of the original auditing intelligent contract deployed in the blockchain may be called first, and the preliminary checking may be performed on the work to be audited. And if the preliminary check is passed, further calling a sending logic in the contract code of the original auditing intelligent contract deployed in the block chain.
In practical applications, the nodes of the block chain may be identified in advance by an original audit intelligence contract including check logic. The check logic has multiple check modes and can correspond to different work types.
For example, when the type of the work to be checked is a picture, the checking logic may be a picture similarity check. When the type of the work to be checked is text, the check logic may be hash check. The correspondence between the check logic and the work type may refer to related technologies, and is not particularly limited herein.
After a user initiates an audit transaction through an external account, the node corresponding to the external account may first determine the type of the work to be audited corresponding to the user. After the type of the work to be audited is determined, the node can call the checking logic corresponding to the work type in the contract code of the original auditing intelligent contract deployed in the block chain, so as to perform preliminary checking on the work to be audited.
If the preliminary verification passes, the to-be-inspected works can be considered to be qualified after the preliminary verification, and further manual verification is needed. At this time, the node may further invoke a sending logic in the contract code of the original audit intelligence contract deployed in the block chain, so that each audit node performs original audit on the to-be-audited work.
If the preliminary verification is not passed, the work to be examined can be determined as the plagiarism-suspected work in the preliminary examination stage. At the moment, manual auditing of the auditing nodes (auditors) can be avoided, workload of the auditing nodes can be reduced, and auditing efficiency is improved.
When each auditing node returns the auditing result to the original auditing intelligent contract according to the auditing sequence, the determining logic in the contract code of the original auditing intelligent contract can be further called, and the final auditing result aiming at the to-be-audited works is determined based on the auditing result returned by each auditing node.
In one embodiment, the determination logic may be a minority-compliant majority. Specifically, if the number of the audit nodes with the audit result of passing is greater than the number of the audit nodes with the audit result of failing, the final audit result of the to-be-audited work is determined as the audit passing; otherwise, the audit is determined to be not passed.
In another embodiment, the determination logic may be an absolute threshold method. Specifically, the number of the auditing nodes whose auditing results are passed may be counted, and the number may be compared with a preset threshold. If the number reaches the preset threshold value, determining that the final audit result aiming at the to-be-audited works is approved; otherwise, the audit is determined to be not passed. The preset threshold may be set by a developer based on experience; or calculated based on a neural network model.
After the final audit result of the to-be-audited work is determined, the node corresponding to the user can give feedback to the user based on the final audit result.
In one case, if the final audit result is that the audit is not passed, the node may prompt the user of the audit result through a display unit, and may further present the reason why the audit is not passed to the user through the display unit, so that the user may modify the work based on the reason.
In another case, if the final audit result is that the audit is passed, the node may determine that the work uploaded by the user is a creative work and may disclose the creative work to the internet, and make a corresponding prompt to the user. In practical application, the node can automatically display the works through a public platform (for example, know, search fox, and the like); or the node may disclose the works after permission of the user.
In an embodiment, in order to avoid that the user frequently submits work audit maliciously, when the user initiates an audit transaction, a part of audit fee may be deducted from an account corresponding to the user.
The examination fee is a cost required for the original examination. In one case, the audit fee may be a gasoline fee resulting from executing the smart contract. In another case, the audit fee may be an audit offer of an auditor. It should be noted that the type of the audit fee may be determined according to actual situations, and is not limited herein.
At this time, since the audit fee is the fee to be submitted by the user when initiating the audit transaction, a certain expense is caused to the user, so that the user can initiate the audit transaction only when having a real requirement, thereby avoiding the user from submitting the work audit maliciously and frequently.
Thirdly, replacing the auditing node
In order to urge the auditing node (auditor) to carry out original auditing operation, the application also provides a method for replacing the auditing node.
Specifically, after the final audit result corresponding to the work to be audited is determined each time, the audit result of each audit node may be compared with the final audit result, and the audit accuracy corresponding to each audit node is updated based on the comparison result;
the above-mentioned audit accuracy specifically refers to a probability that an audit result of a corresponding node for a certain work is consistent with a final audit result of the work. When the auditing correctness rate corresponding to a certain node is calculated, the counted number of times that the auditing result of the node which has finished auditing is consistent with the final auditing result corresponding to each auditing can be divided by the number of times that the block chain where the node is located undertakes original auditing.
For example, assume that the block chain in which node a is located has already undertaken 50 original audit jobs. The number of times that the audit result of the node a in the 50 audits is consistent with the final audit result corresponding to each audit is 40. Therefore, the audit correctness rate corresponding to the node a is calculated to be that 40 divided by 50 equals to 80%.
In practical application, the probability that the audit result is consistent with the final audit result when the corresponding node is audited aiming at the new to-be-audited work can be predicted based on the audit accuracy rate, so that the operation capability of the corresponding node is reflected,
since the audit nodes in the application are audited according to the randomly determined audit sequence, the audit node at the end of the audit sequence may copy the audit nodes before the audit node to make a false audit, and thus the corresponding audit accuracy rate is improved. In order to avoid the above situation, when the auditing correctness rate corresponding to the auditing node is changed, the auditing nodes can be firstly sequenced according to the auditing sequence of the auditing nodes; and then, updating the auditing correctness rates corresponding to all auditing nodes from the sequenced first node to the Mth node. The above M may be set by a developer according to a need or experience, and is not particularly limited herein.
Since the audit node corresponding to the audit node at the end of the audit sequence (after the mth node) is not updated, it is possible to avoid that the audit node performs a false audit to improve the corresponding audit accuracy.
When a user initiates an audit transaction, the audit transaction is sent to an audit node for original audit verification, and interaction with a non-audit node can be carried out, so that the non-audit node can also audit the to-be-audited works.
Specifically, the non-audit node may read the works uploaded by the user in the block chain, and make a corresponding audit result for the to-be-audited works based on an audit method (e.g., a retrieval comparison method). After the audit result is obtained, the non-audit node can encrypt and store the audit result, and upload the encrypted audit result to the block chain.
After the final audit result of the to-be-audited work is determined, the non-audit node may upload the decryption key to the block chain, so that other nodes in the block chain obtain the audit result of the non-audit node, thereby comparing the audit result of each non-audit node on the to-be-audited work with the final audit result, and updating the audit accuracy of each non-audit node based on the comparison result.
In one embodiment, the above-described change audit node procedure may be initiated periodically. Specifically, the following steps may be periodically performed on each audit node in the block chain in sequence: and determining whether the checking accuracy of the checking node reaches a preset threshold value.
And if not, determining the non-audit node with the maximum audit accuracy from the non-audit nodes, and replacing the audit node with the determined non-audit node.
And if so, indicating that the auditing accuracy of the auditing node reaches the standard. The audit node is not replaced.
The preset threshold is generally the auditing accuracy rate accepted by the industry in the original auditing field. The threshold value may be set by a developer based on experience, or obtained by a neural network algorithm, and is not limited herein.
For example, assume that the preset threshold is 70%. If the auditing correctness rate corresponding to a certain auditing node does not reach 70%, the auditing correctness rate of the auditing node does not reach the standard, the working capacity is poor, and the node is required to be replaced. Therefore, in the above better auditing node procedure, the auditing node can be replaced by the non-auditing node with the highest statistical auditing accuracy.
According to the program, the auditing node can always keep high auditing accuracy through the method for replacing the auditing node, so that the auditing node is supervised and urged.
In another embodiment, the last elimination may be used to replace the auditing node.
In practical application, the auditing nodes and the non-auditing nodes can be respectively sequenced from high to ground according to the respective corresponding auditing correctness rates of the auditing nodes and the non-auditing nodes. Then, the correct auditing rate of the auditing node at the end is compared with the correct auditing rate of the non-auditing node at the head.
If the non-audit node has a high contention rate, replacing the audit node with the non-audit node; otherwise, no replacement operation is performed.
And the adoption of the tail elimination system can still effectively urge the audit node to carry out audit work, thereby improving the quality and efficiency of original audit.
In another embodiment, the related operation of replacing the auditing node can also be carried out by using a mode of large shuffling periodically.
In practical application, the auditing nodes and the non-auditing nodes can be mixed together for sequencing according to the auditing accuracy, and then the node with the top N ranking is selected as the auditing node. And N is the number of the auditing nodes preset by the original auditing platform.
By adopting the mode of regularly shuffling the cards greatly, the auditing nodes can be effectively supervised and urged to audit, so that the original auditing quality and efficiency are improved.
The following describes embodiments of the present application with reference to an actual scene.
Referring to fig. 2, fig. 2 is a structural diagram of an original auditing platform built based on a blockchain network according to the present application. As shown in fig. 2, the original auditing platform is constructed based on a block chain. The block chain comprises a plurality of nodes. The nodes comprise auditing nodes which are selected by an election algorithm. The auditing node in the block chain can respond to the auditing transaction initiated by the user and carry out original auditing on the to-be-audited works uploaded by the user.
After a user initiates an audit transaction through a corresponding account of the user, the node 1 corresponding to the account can call a sending logic in the original audit intelligent contract, and the audit transaction can be sent to each audit node for audit.
Each audit node can upload respective audit results according to the randomly determined audit sequence.
After the node 1 receives the auditing results submitted by the auditing nodes, the determining logic in the original auditing intelligent contract can be called to determine whether the number of the auditing results passing the auditing nodes reaches the preset threshold value.
If the result is reached, the node 1 can determine that the work is the original work. After determining that the works uploaded by the users are original works, the node 1 can interact with the users through the carried interaction module to determine whether the users disclose the original works. If the node receives a response that the user confirms disclosure, the creative work can be sent to a server side corresponding to a disclosure platform (for example, a client), so that the disclosure of the creative work is completed.
