Finally, the original author can protect own article copyright through an original author copyright maintenance module in the system.
The article publishing company functional module comprises a transaction proposal consensus module, an auction quotation submitting module, a copyright article management module and a publishing company reddening module; the transaction proposal consensus module is the basis of a copyright article generation module and an auction module in the system, and can consensus the basic information of the copyright article so as to link the information of the copyright article and can also consensus the auction amount and ownership of the copyright article. An auction bid module is submitted through which a publisher can initiate a bid in an auction campaign. And the copyright article management module is aimed at a publishing company which owns the copyright article ownership, and can set the authority of a certain copyright article by the publishing company and can conduct secondary auction on the copyright article according to the real-time article value. Finally, the scoring module of the publishing company prescribes the scoring rule of the publishing company in the auction, and the earning earnings of the publishing company in the auction are ensured.
The system basic functional module specifically comprises a node consensus algorithm module, an intelligent contract execution module, a related certificate issuing module and an on-chain data query module, and the copyright article assisting module provides a rule for the consensus group node in the transaction proposal consensus module to complete consensus with which consensus algorithm, and the optimized PBFT consensus algorithm is cited and the quality of the consensus group node can be effectively improved by being matched with the construction of a node credit model. And the intelligent contract execution module is used for realizing requirements such as generation of the copyright articles, auction bartering and the like in the system in the form of intelligent contracts, so that related requirements can be realized in time after node consensus is finished. And the related certificate issuing module is the basis of joining the system alliance chain by the publishing company, wherein a CA organization contained in the related certificate issuing module can issue an access certificate for the publishing company, and can provide an electronic copyright certificate for an original author. And the on-chain data query module mainly provides verification functions for users, namely, the users can check some key information such as whether the information of the copyright articles is successfully linked up and whether the ownership of the copyright articles is transferred. And the copyright article auxiliary module can assist the original author to carry out NFT on the original article autonomously, so that the copyright article is generated. Specifically, the method can convert the basic information of an article submitted by a user when the NFT of the article is performed into a JSON format file so that an original author can send a request proposal to a consensus group in a transaction proposal consensus module, thus the article information is initially consensus, and the information of an article is recorded on a blockchain through consensus, and finally a copyright article is generated.
The node in the node consensus algorithm module is divided into consensus nodes and candidate nodes, the consensus groups are formed by the consensus nodes to participate in the consensus process and achieve the consensus result, the candidate nodes are used as substitutes of the consensus nodes and do not participate in the consensus process, but need to accept the consensus result, a node reputation model is built in the node consensus algorithm module, the behavior of the node in each round of consensus flow is monitored, the nodes are judged by changing the node reputation value, and when the reputation value of a certain node is too low, the node is removed from the consensus groups, so that the quality of the node of the whole consensus groups is improved.
The reputation model comprises the following three parts: monitoring the behavior of the consensus nodes, updating the reputation value of the consensus nodes and updating the nodes in the consensus group. The node reputation model is constructed and the reputation value of the consensus node is calculated as follows: the reputation value of a publisher as a consensus node is initialized to 60, up to 100, which will be updated according to the following formula:
；
wherein ,Rrepresenting the degree of reputation of the user,indicate->The common knowledge of the wheels is that,xrepresenting a security parameter; if a consensus node has no malicious behavior and is actively involved in consensus, it will be marked as an honest node, and its reputation value will increase in logarithmic form; if a certain consensus node does not generate a valid blockOr not timely sending voting information, indicating that the node is not actively involved in the consensus process, the reputation value of the node is linearly reduced, namelyxFalls within the interval (0, 1); if the information sent by a node is inconsistent with other nodes, then it is marked as a malicious node, the reputation value will be reduced directly to 1, meaning that the node will be removed from the consensus group, and the system will select the remaining candidate nodes to supplement the consensus group.
The consensus node is divided into a master node and a slave node, wherein the master node is responsible for initiating block proposal, collecting and calculating ticket numbers to determine a consensus result. The slave node is responsible for voting on the proposed block to assist in achieving the correct consensus result. In the traditional practical Bayesian consensus algorithm, a simple remainder method is generally adopted to determine the identity of the master node, and the method easily exposes the identity of the master node in advance so as to cause the master node to be attacked, thereby influencing the node consensus efficiency in the system blockchain network. Therefore, in this embodiment, an optimized PBFT consensus algorithm is applied to the present copyright protection system, and the specific optimization method of the consensus algorithm is as follows: a verifiable random function is added in the master node selection method so as to realize dynamic random selection of the master node, the identity of the master node can be verified by other nodes, and meanwhile, the quality of the whole consensus group node can be effectively improved by matching with the constructed node reputation model, so that the usability of the system in the aspect of node consensus is improved.
The verifiable random function (Verifiable Random Function) is a pseudo-random function with verification function, which mainly comprises three parts: key pair generation algorithmG、Value-ProofGenerating algorithmSRandom number verification algorithmV. For a particular inputxPrivate key of inputterSKThe verifiable random function outputs a random numbervOne proofproofThe verifier can verify whether the random number is generated by the input through the three parts of the output random number, the proof and the initial input. Generated random numbervNode reputation value in node reputation modelRWill have an important impact on whether a node can be selected as the master node. Specific master node extraction and generation of effective proposals such asAlgorithm 1;

Second, the generation of the master node depends largely on the value of the random number that it generates itself, while the generation of the random number for each node depends on the seed. Thus, the security of the seed determines the security of the master election. The initialization of the seeds in this embodiment is shown as follows:
wherein NFor the total number of nodes, the public keys of all nodes in the consensus group are obtainedPKPerforming a hash operation to obtain initial seedSeed 0 Meanwhile, in order to avoid the seed being operated by a malicious node, the seed is refreshed every n rounds, and the refreshing mode is as follows: the master node of the nth round receives 2fThe public key of +1 slave nodes (including the master node) is operated in a similar way to the above formula, and the obtained result is a new seedSeed i The method comprises the steps of carrying out a first treatment on the surface of the Random number related to step 2 of algorithm 1ValueProof ofProofFrom verifiable random functionsValue-ProofGenerating algorithmSCan be specifically expressed as, wherein S 1 Private key through input nodeSKSeed and seedSeedGenerating random numbersValueCan be specifically expressed as->，S 2 By and withS 1 The same input is used for generatingProof，Can be specifically expressed as->The method comprises the steps of carrying out a first treatment on the surface of the Step 3 in algorithm 1, the slave node passes the verification algorithmVThereby verifying from the master nodeValueValue by inputting master node public keyPKSeed(s)SeedRandom numbers from master nodesValueProof ofProofTo verify random numbersValueFurther verifying the validity of the proposal from the master node, which can be expressed in particular as:V(PK, Seed, proof, value)→true/falsethe built-in judgment conditions of the algorithm are as follows: if random numberValueThe following formula is satisfied:

The method for calculating the score obtained by each cited seal comprises the following steps: if the article currently referenced by the auction article isiThis is, howeveriThe cited times of the article are respectivelym 1 , m 2 ,… m i Then each of these cited marks occupiesP 2 The red dividing ratio of (2) is respectively
。
The method separates the auction avails of originators from the quoted chapter numbers, effectively avoids some originators from hiding the quoted chapter information in order to maximize avails, if an article is not introduced into any article=0. Secondly, the reddening among the quoted marks is carried out according to the reference times of the articles, so that the income of the high-quality articles in the system can be remarkably improved, mutual learning and reference among originators are facilitated, the circulation of the articles in the system is promoted, and the awareness of the originators and the income of the articles are improved
Step 5: the publishing agent which acquires the copyright article ownership through auction uses the copyright article management module to set the reading authority of the copyright article, and judges the real-time value of the article according to the information fed back by the common user function module, thereby determining whether to conduct online auction on a copyright article again;
step 6: if the publishing agent decides to conduct secondary auction on the copyright article, other publishing agents can continuously conduct bidding on the copyright article through the auction quotation submitting module, if the bidding is successful, the publishing agent initiating the auction determines final payment amount on the basis of the node consensus algorithm module through the transaction proposal consensus module, and the intelligent contract executing module is matched to complete transfer of copyright ownership of the copyright article. The publishing company initiating the auction and the related originators can acquire corresponding benefits through respective reddening modules and matching with an intelligent contract executing module;
in step 6, the red-out mechanism of the secondary auction of the copyright article by the publishing agency is specifically as follows: in order to avoid overlong auction period, the system is set to be redP 3 And satisfy a function ofP 1 But hereP 3 No longer contains the marked seal for reddening, and the final price is set asQThe original author and the cited article are respectively divided into redFinal benefit of publishing house->；
For articles with the quoted times reaching the standard, the system takes out a part of the obtained score as a reward to the original person, and sets the part of the score asP 4 ，A security interval for the number of article introduction, wherein +.>，mFor the articles to be referred to by the reference number,P 4 the calculation formula of (2) is as follows:
。
step 7: if the copyright of a certain original author is infringed, the related certificate issuing module and the on-chain data query module are used for acquiring the copyright certificate or the information on the copyright article chain to maintain the copyright of the original author.
The reference quotation relation between copyright articles is realized by writing an intelligent contract code (ERC-5521 protocol, which is an improved version of NFT basic ERC-721 protocol) which is open in an Ethernet community into the system, so that the reference and the referenced relation between the NFT are introduced while the system is used for NFT of an original article, and the original author can choose to enable the NFT issued by an individual to appear in a system NFT relation network in the 'ancestor' identity, namely the article does not quote any other article. This approach in the present system may provide a reliable, trusted, and transparent history that allows users to query to track and analyze their relationships.
FIG. 4 is a diagram illustrating an optimized practical Bayesian consensus process of the present invention, wherein first, nodes in a consensus group determine a master node by running a verifiable random function, then the master node receives a transaction proposal from a client and generates a block broadcast to all network nodes, each slave node verifies the identity of the master node and votes for block information according to a conventional consensus algorithm process (mainly including three phases of Pre-preparation-Commit), sends the voting result to other nodes except itself, and when a node receives 2fAfter a Prepare message from the other node, it may send a wait message to the other node indicating that the proposal has been agreed to by most nodes. Finally, the consensus node counts the voting result, if agreeing to the sum of the reputation values of the proposed nodes,/>, wherein NAs a total number of nodes,ffor the number of abnormal nodes, according to the algorithm requirement,fand (3) withNSatisfy->. At this point, the block will be committed, otherwise, the blockThe block will be discarded as an illegal or invalid block. Finally, the algorithm evaluates the behavior of each consensus node, updates the reputation value of the consensus node, and adjusts the state of the consensus node according to the reputation model constructed by the system.
FIG. 5 is a flow chart showing the transaction auction and ownership change of an article according to the present invention, which adds an article auction mechanism to increase the popularity of the article, thereby increasing the popularity of the original, and increasing the profits of the original while guaranteeing the copyright of the original. The auction flow is generally as follows: by accepting the bid port, the auctioned copyright article can receive bids from different publishers and store the bids in the IPFS as a data source. And the user decides whether to terminate the auction according to the real-time avails fed back by the system, if the auction is terminated, the bid receiving port is closed, and the NFT right-determining and avail-scoring stage is entered. The system feeds back the auction result and the payable amount to the client, the buyer client pays online, the payable amount is stored in the intelligent contract and the payable amount is distributed to all parties according to the red-out mechanism of the system. At the same time, the buyer client initiates a proposal requesting to change the ownership of the NFT, links up the new block through a consensus mechanism, here marks that the copyright and ownership of the copyright article are successfully separated, and finally the auction ends, the copyright article appears in the homepage of the publishing company owning the copyright article, and the user obtains the right to read the copyright article by accessing the homepage of the publishing company.
The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, the scope of which is defined by the claims. Various modifications and equivalent arrangements of this invention will occur to those skilled in the art, and are intended to be within the spirit and scope of the invention.
