The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission (P2P transmission), a consensus mechanism, an encryption algorithm and the like, and is essentially a decentralized database; the blockchain can be composed of a plurality of serial transaction records (also called blocks) which are connected in series by cryptography and protect the contents, and the distributed accounts connected in series by the blockchain can effectively record the transaction by multiple parties and can permanently check the transaction (can not be tampered). The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.

The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after consensus on the valid request is completed, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the service information to a shared account (network communication) completely and consistently after encryption, and performs recording and storage; the intelligent contract module is responsible for registering and issuing contracts, triggering the contracts and executing the contracts, developers can define contract logics through a certain programming language, issue the contract logics to a block chain (contract registration), call keys or other event triggering and executing according to the logics of contract clauses, complete the contract logics and simultaneously provide the function of upgrading and canceling the contracts; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.

An intelligent contract may be understood as a computer program that runs on a distributed ledger (i.e., blockchain) that presets rules, has status, conditional responses, can encapsulate, validate, execute complex behaviors of distributed nodes, and performs information exchange, value transfer, and asset management. Based on a distributed architecture, a consensus algorithm and the like of a block chain, the intelligent contracts allow users who are not trusted to finish transactions without any trusted intermediary or authority of a third party, and meanwhile, the digital intelligent contracts can be flexibly embedded into various tangible or intangible assets, transactions and data, so that active or passive assets, information management and control are realized, and programmable intelligent assets, systems and the like are gradually constructed.

Fig. 1 is a diagram of a network architecture according to an embodiment of the present application. As shown in fig. 1, the network architecture includes a terminal device 10e, a terminal device 10f, and a plurality of nodes (specifically, as shown in fig. 1, a node 10a, a node 10b, a node 10c, and a node 10d) in a blockchain network. The node 10a, the node 10b, the node 10c and the node 10d are all block link points in a block link network, and may be a node server or other node devices; the terminal device 10e may be a user terminal that initiates a data uplink request, the terminal device 10e may upload copyright information of a work that needs to be uplinked to a block chain network, and any block chain node (e.g., the node 10a) in the block chain network may generate a new block according to the copyright information of the work uploaded by the terminal device 10e, and broadcast the newly generated block in the block chain network, so that a node in the block chain network recognizes the newly generated block, that is, after the node 10a newly generates the block, the newly generated block may be broadcast to the node 10b, the node 10c, and the node 10d, and the block that passes the recognition may be formally uplinked, and the node in the block chain network may store a block chain in a local area. The terminal device 10f is a user terminal initiating a work use request, when a user uses a work, the user terminal corresponding to the user can send the use request to the blockchain network, the blockchain network can charge a certain copyright fee to the user according to an intelligent contract, and after the charging is successful, the user can be provided with a use permission.

The

terminal devices

10a and 10b may each include a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device (e.g., a smart watch, a smart band, etc.), and the like.

Please refer to fig. 2, which is a schematic diagram of a copyright data processing scenario provided in an embodiment of the present application. As shown in fig. 2, the node 10a may be represented as any blockchain node in a blockchain network, when the product a is created, the ownership of the product a is owned by the copyright owner, when the remaining objects need to use the product a, a certain fee needs to be paid to the copyright owner to obtain the usage right of the product a, and how to collect the fee can be determined by the copyright owner. The terminal device 10e may be represented as a request terminal corresponding to a copyright owner of a work a, and the terminal device 10e may upload the copyright information to be uplink for the work a to the blockchain network, so that a blockchain node (e.g., the node 10a) in the blockchain network may uplink the copyright information to be uplink uploaded by the terminal device 10e, and the copyright information to be uplink may include work information (e.g., name of the copyright work: work a,), copyright owner information (e.g., account information of the copyright owner: account 123) and authorization fee (e.g., c m/month).

After receiving the to-be-uplink copyright information uploaded by the terminal device 10e, the node 10a in the block chain network may verify the to-be-uplink copyright information, and the node after the verification may perform uplink. The verification process may include: detecting whether the received to-be-uplink copyright information is sent by the terminal equipment 10e, namely detecting whether the to-be-uplink copyright information is tampered in the uploading process, which can also be called an signature verification process; after the verification is passed, the node 10a may further detect whether the locally stored copyright block chain 20b already stores copyright information for the work a, if the locally stored copyright block chain 20b already stores the copyright information corresponding to the work a, it indicates that the copyright information of the work a has been formally linked up, and the node 10a may delete the copyright information to be linked up if the received copyright information to be linked up is invalid data; if the copyright information corresponding to the work a is not detected in the locally stored copyright block chain 20b, the copyright information to be linked may be packaged into the copyright block 20a, the block header of the copyright block 20a may include a Hash (Hash) corresponding to the largest block in the locally stored copyright block chain, and after the consensus of the copyright blocks 20a passes, the commonly-known copyright block 20a may be added to the copyright block chain 20b for formal linking.

It should be understood that the terminal device 10e may also upload the intelligent contract written by the developer to the block chain network along with the to-be-linked copyright information, and after the intelligent contract is packaged into the copyright block 20a along with the to-be-linked copyright information and added to the copyright block chain 20B for official linking, it indicates that the intelligent contract for the work a has been successfully deployed in the copyright block chain 20B, and the intelligent contract may set an authorization fee corresponding to the work a for performing a data transfer function, such as transferring the M amount from the account of the object a to the account of the object B.

After the uplink of the copyright information corresponding to the work a is completed, if the user wants to use the work a, the terminal device 10f corresponding to the user may send a usage request for the work a to the blockchain network, where the usage request may carry information of a usage object (i.e., the user) (e.g., account information of the usage object: account 234) and a usage period (e.g., 2 months). After receiving the usage request sent by the terminal device 10f, the node 10a in the block chain network may obtain authorization fee (c element/month) corresponding to the work a from the copyright block chain 20b, and according to the authorization fee and the usage period (2 months) carried by the usage request, may determine that the copyright fee corresponding to the usage object is: c x 2, according to the intelligent contract in the block chain network, the copyright fee of c x 2 amount can be transferred from the account of the use object to the account 123 of the copyright owner, wherein the account of the copyright owner can be obtained from the copyright block chain 20 b.

Please refer to fig. 3, which is a flowchart illustrating a copyright data processing method based on an intelligent contract according to an embodiment of the present application. As shown in fig. 3, the method may include:

step S101, acquiring copyright information to be linked associated with copyright works, generating a copyright block according to the copyright information to be linked, and adding the copyright block to a copyright block chain; the copyright information to be linked comprises work information corresponding to the copyright works, copyright person information and authorized asset distribution rules;

specifically, after obtaining the copyright ownership of the copyrighted work, the work copyright owner may upload copyright information (which may be called to-be-linked-up copyright information) for the copyrighted work to the blockchain network through the data submission node (which may be a client corresponding to the copyright owner, such as the terminal device 10e in the embodiment corresponding to fig. 2), where the to-be-linked-up copyright information may include: the copyright information corresponding to the copyright works, the copyright owner information, the authorized asset allocation rule and the like; the copyright works can be multimedia data, such as video, audio, images, texts, software application and the like; the copyright owner refers to an individual or a unit owning the ownership of the copyright work, and when the copyright owner is the copyright owner, the information of the copyright owner can be information such as an individual name, an identity card number, an individual account and the like; when the copyright person is a unit, the copyright person information can be information such as a unit name, a unit code, a unit account and the like; the authorized asset allocation rule may refer to a rule established to charge a copyright fee, i.e., an authorization fee for the copyrighted work. Before a data submitting node corresponding to a copyright owner uploads copyright information to be linked to a block chain network, the data submitting node can adopt an asymmetric encryption algorithm to establish a key pair; asymmetric encryption algorithms herein may include, but are not limited to: the Elgamal algorithm (an asymmetric encryption algorithm), the Rabin algorithm (an asymmetric encryption algorithm), the Diffie-Hellman algorithm (an asymmetric encryption algorithm), the ECC algorithm (elliptic curve encryption algorithm). The key pair may include a public key and a private key, and the private key is used for the data submitting node to digitally sign the to-be-uplinked copyright information uploaded to the blockchain network. After creating the key pair, the data commit node may upload the public key of the key pair to the blockchain network, while the private key is kept by the data commit node. It should be noted that public keys in the blockchain network are unique, and one public key corresponds to one data submitting node.

After the data submitting node uploads the public key to the blockchain network, the data submitting node indicates that the data submitting node completes identity registration in the blockchain network, and the data submitting node has the qualification of data submission and information viewing in the blockchain network at the moment. Therefore, the data submitting node at this time can upload the copyright information to be uploaded to the blockchain network. After receiving the to-be-linked-chain copyright information uploaded by the data submitting node, the block chain node (e.g., the node 10a in the embodiment corresponding to fig. 2) may generate a copyright block (e.g., the copyright block 20a in the embodiment corresponding to fig. 2) according to the to-be-linked-chain copyright information, and add the copyright block to the copyright block chain (e.g., the copyright block chain 20b in the embodiment corresponding to fig. 2).

It should be understood that after receiving the copyright information to be uplink uploaded by the data submitting node, the block chain node may perform signature verification on the received copyright information to be uplink according to a public key corresponding to the data submitting node; generating a copyright block according to the copyright information to be linked, which passes the verification, and broadcasting the copyright block to a consensus node in a block chain network so that the consensus node verifies the copyright block; and when the number of the received verification passing messages of the consensus node is greater than the number threshold, determining that the copyright block consensus passes, and adding the copyright block which passes the consensus to the copyright block chain.

The process of the block chain node for checking the copy information to be uplinked specifically comprises the following steps: the block chain node can decrypt the digital signature carried by the copyright information to be uplink according to a public key corresponding to the data submitting node, acquire first abstract information corresponding to the digital signature, further perform hash operation on the received copyright information to be uplink according to a hash algorithm, generate second abstract information corresponding to the received copyright information to be uplink, if the first abstract information is detected to be the same as the second abstract information, the copyright information to be uplink passes the verification, generate a copyright block according to the copyright information to be uplink, and add the agreed copyright block to the copyright block chain. If the digital signature carried in the to-be-uplink copyright information received by the block chain node is not the digital signature of the data submission node, that is, the digital signature in the to-be-uplink copyright information is the digital signature generated by using the false private key, the block chain node directly displays that the decryption fails when decrypting by using the real public key. The first abstract information is abstract information aiming at the copyright information to be uplink, which is obtained by the data submission node according to the Hash operation calculation, the second abstract information is abstract information aiming at the actually received copyright information to be uplink, which is obtained by the block chain node according to the Hash operation calculation, and the Hash algorithm used by the data submission node and the block chain node is the same.

The hash algorithm may compress data or messages into digests, not only fix the format of the data, but also reduce the amount of the data, and the hash algorithm may include, but is not limited to, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. Taking the SHA-256 algorithm as an example, the SHA-256 algorithm can generate a 256-bit hash value for any size of data, and can generate different hash values for different data.

The specific process of the block link point identifying the copyright block specifically comprises the following steps: the block chain node may broadcast the generated copyright block in the block chain network, that is, the copyright block is sent to the other nodes in the block chain network in a point-to-point transmission manner, after the other nodes verify the copyright block, the verification result may be broadcast in the block chain network, when a node exceeding a number threshold (the number threshold is associated with a common identification mechanism, and different common identification mechanisms may correspond to different number thresholds, such as 51%) in the block chain network passes the copyright block, it indicates that the copyright block passes the common identification, and the copyright block may be added to the copyright block chain for formal uplink. Wherein, the consensus algorithm includes but is not limited to: proof of Work (PoW), Proof of rights (PoS), Proof of Work and Proof of rights (PoW + PoS), Proof of equity authorization (Delegated Proof of stamp, DPoS), Practical bypath Fault-tolerant algorithm (PBFT), and Rayleigh Consensus Protocol (RCP).

Please refer to fig. 4, which is a diagram illustrating a chain of copyright blocks written in the copyright block provided by the present application. As shown in fig. 4, the node 10a may obtain a generation timestamp corresponding to each block in the copyright block chain 30e, where a block with a largest generation timestamp is a block with a largest block height in the copyright block chain 30 e; obtaining a hash value (namely, a previous block hash value) corresponding to the block with the largest block height and the current time, generating a hash value (namely, a current block hash value) corresponding to the to-be-linked-chain copyright information, and generating a block header 30b in the new block based on the previous block hash value, the current time and the current block hash value; the block body 30c in the block to be verified is generated based on the copyright information to be linked, and the block 30a can be generated according to the block header 30b and the block body 30 c. The node server may broadcast the generated tile 30a to the rest of the blockchain nodes in the blockchain network 30d (the blockchain network 30d includes the node 10a), analyze the to-be-uplink copyright information in the tile 30a through a consensus algorithm, and determine whether the work information, the copyright owner information, and the authorized asset allocation rule in the to-be-uplink copyright information are valid information. If it is determined that the to-be-linked copyright information in the block 30a is valid data and the data storage structure in the block 30a conforms to the data structure specified by the copyright block chain 30e, it indicates that the block 30a passes the verification and returns the verification result to the node 10 a. When most of the blockchain nodes (e.g., more than 50% of the blockchain nodes) in the blockchain network return a verification result to the node 10a, it indicates that the block 30a is verified, and the verified block 30a may be added to the copyright blockchain 30 e.

Optionally, the data submitting node may also upload an intelligent contract compiled by a developer to the block chain network along with the to-be-linked copyright information, the block chain node performs signature verification according to the to-be-linked copyright information carrying the intelligent contract, generates a copyright block, and performs formal linking after the copyright block passes the common identification, which indicates that the intelligent contract is successfully issued in the block chain network. The intelligent contract refers to a computer program code written by a developer by using an intelligent contract high-level language, the intelligent contract written by the high-level language can be compiled into byte codes in an Ethernet workshop virtual machine of the block chain nodes through a compiler, and the Ethernet workshop virtual machine can be used for interpreting and executing the byte codes in the intelligent contract. The intelligent contract high-level languages include, but are not limited to, identity (an intelligent contract programming language), Serpent (an intelligent contract programming language), and LLL (an intelligent contract programming language), for example, a developer may write an intelligent contract using identity, and use a compiler to compile the intelligent contract written by identity into an ethernet virtual machine byte code, and then submit the compiled ethernet virtual machine byte code to a blockchain network along with transaction data and uplink the ethernet virtual machine byte code. A plurality of contract methods such as a method of setting an authorized asset allocation rule, a method of setting a copyright holder account, a method of setting a use object account, and the like may be included in the smart contract.

Step S102, when receiving a usage request of a target object for copyrighted works, obtaining authorized asset allocation rules associated with the copyrighted works from a copyright block chain, and determining a transfer data volume corresponding to the target object based on the authorized asset allocation rules and a service life carried by the usage request;

specifically, after the copyright information corresponding to the copyrighted work is stored in the uplink, when a usage request of a target object for the copyrighted work is received, the block link point may obtain a usage period carried by the usage request, and may also obtain an authorized asset allocation rule associated with the copyrighted work from the copyrighted block chain, and according to the authorized asset allocation rule and the usage period, may determine a transfer data volume corresponding to the target object, where the transfer data volume may be a copyright fee that the target object should pay to use the copyrighted work, and the copyright fee is determined by the usage period of the target object and the authorized asset allocation rule corresponding to the copyrighted work. For example, the authorized asset allocation rule that the blockchain node acquires the copyrighted work from the copyrighted blockchain is as follows: m yuan/year (i.e. authorization fee), the service life carried in the use request is: in 3 years (namely the period of applying for the target object to use the copyrighted work), the transfer data volume corresponding to the target object can be determined to be 3 × m elements; when the copyrighted work is a game application, the authorized asset allocation rule of the copyrighted work may be: n tokens/month, and when the service life carried in the use request is 2 months, it can be determined that the transfer data amount corresponding to the target object is 2 × n tokens. In other words, the data amount to be transferred corresponding to the target object may refer to digital assets such as rmb, dollar, and the like, or may refer to virtual assets such as game coins and the like.

Optionally, when the authorization requester applies for the usage right for the copyrighted work to the copyright owner, and when the authorization requester and the copyright owner achieve authorization intention and sign an authorization agreement, an authorization uplink request for the copyrighted work may be sent to the blockchain network, so as to apply for uplink storage of information of the authorized person (i.e., the authorization requester) and an authorization duration to the blockchain network. After receiving an authorized uplink request sent by an authorized requester, a block chain node can acquire work information, authorized person information and an authorization deadline carried by the authorized uplink request; when detecting that the copyright block chain has the work information, packaging the work information, the information of authorized persons and the authorization time limit into an authorization block, and adding the authorization block to the copyright block chain; the authorization block is used for recording object information having a usage right of a copyrighted work. In other words, the copyright owner can authorize the usage right of the copyrighted work to the authorization requester, and can uplink store the authorization information (including the information of the work, the information of the authorized person, the authorization period and the like) of the copyrighted work during copyright authorization. After receiving the authorization information, the block chain node also needs to check and sign the received authorization information, and after the check and sign are passed, a new authorization block can be generated, and the authorization block which passes the consensus is added to the copyright block chain. The signature verification process of the authorization information and the consensus process of the authorization blocks may refer to the description in step S101, and are not described again.

After the authorization information corresponding to the copyrighted work is subjected to uplink storage, when a block link point receives a use request of a target object for the copyrighted work, acquiring a historical block associated with the copyrighted work from a copyrighted block link; the history blocks comprise authorization blocks and copyright blocks; if the target object information carried by the use request is inconsistent with the information of the authorized person in the authorization block, determining the transfer data volume corresponding to the target object based on the authorized asset allocation rule in the copyright block and the service life carried by the use request; if the target object information carried by the use request is consistent with the information of the authorized person in the authorization block, and the service life belongs to the authorization life, determining the target object as an authority opening state; if the target object information is consistent with the authorized person information and the service life does not belong to the authorized period, the copyright fee (i.e. the transfer data volume) corresponding to the target object is determined based on the authorized asset allocation rule and the service life in the copyright block. In other words, when the block link node receives a request for using the copyrighted work from a target object, it may verify whether the target object is an authorized person of the copyrighted work according to authorization information stored in the copyrighted block chain, that is, determine whether the target object information is the same as the authorized person information in the authorization information, and if the target object information is not the same as the authorized person information in the authorization information, determine a transfer data size corresponding to the target object according to an authorized asset allocation rule and a service life carried in the request for using. If the target object information is the same as the information of the authorized person in the authorization information, further comparing whether the service life carried in the use request belongs to the authorization life in the authorization information, if the service life belongs to the authorization life, determining the target object to be in an authority opening state, namely the target object can not pay copyright fees to the copyright person during the authorization period (in the embodiment of the application, all the copyright fees during the authorization period are paid when the authorized person and the copyright person sign an authorization protocol by default, so that the copyright fee can not be paid when the copyright work is used during the authorization period), and then using the copyright work; if the service life does not belong to the authorized life, the copyright fee corresponding to the target object is determined according to the authorized asset distribution rule and the service life.

Optionally, the transfer data size corresponding to the target object may be determined by calling an intelligent contract in the copyright block chain, and when a request for using the copyright work by the target object is received, the intelligent contract in the copyright block chain may be triggered, and the data size to be transferred of the target object is determined by executing the intelligent contract.

And step S103, acquiring the transfer data volume from the account of the target object based on the intelligent contract, transferring the transfer data volume to the account corresponding to the copyright owner, and setting the use permission of the copyright works for the target object.

Specifically, the block link point may obtain a copyright block for the copyrighted work from the copyright block chain, read account information of a copyright holder from the copyright block, input an intelligent contract with the account information for the target object and the account information of the copyright holder, which are carried in the use request, as parameters, call the intelligent contract to obtain the transfer data amount from the account of the target object and transfer the transfer data amount to the account corresponding to the copyright holder, and set the use permission for the copyrighted work for the target object. In other words, after the blockchain node deducts the transfer data amount from the account balance of the target object and adds the deducted transfer data amount to the account of the copyright owner, the blockchain node may open the usage right for the copyright work for the target object. For example, the copyrighted work is video data in a network playing platform, when a user a (i.e., a target object) wants to view the video in the network playing platform, a client corresponding to the user a may send a use request to a blockchain network, where the use request may carry account information of the user a and a term (i.e., a use term) for the user a to apply for viewing the video, and after receiving the use request sent by the client corresponding to the user a, a blockchain node may determine a copyright fee (i.e., a transfer data amount) that the user a should pay according to an authorization fee associated with the video in a copyright blockchain and the term for the user a to apply for using the video, and when the blockchain node deducts the copyright fee from the account of the user a and transfers the copyright fee to the account of the video copyright owner, the blockchain node may grant the use right (including viewing the video, playing the video) to the user a, Permission to forward video, etc.), that is, after payment of the copyright fee is successful, the user a can successfully watch the video.

Optionally, the block link points may further obtain a historical work set from the work publishing platform based on the time period parameter; the work history set comprises all history works published in the work publishing platform in a time period; determining the similarity between each historical work in the historical work set and the copyright work in the block chain, determining the historical work with the similarity larger than a similarity threshold value as the similar work corresponding to the copyright work, and acquiring the publisher information corresponding to the similar work; if the publisher information is inconsistent with the information of the copyright person corresponding to the copyright work, determining the similar work as an infringement state; and generating infringement prompt information aiming at the similar works based on the infringement state, and sending the infringement prompt information to the terminal equipment corresponding to the publisher of the similar works. The work publishing platform is a platform for publishing the works for reading, viewing and interacting by users, such as a network video playing platform, a content interaction platform, an audio playing platform and the like, the historical works refer to the works published on the work publishing platform, and the infringement refers to the fact that a publisher publishes the works in the work publishing platform under the condition that the publisher does not obtain the copyright of the works, and the infringement is the infringement.

The block chain link point can acquire all works issued in a period of time from the work issuing platform at intervals (time period parameters can be set in the intelligent contract) to form a historical work set. Of course, the block link points can only obtain historical works of the same type as the copyrighted works from the work publishing platform to form a historical work set, and if the copyrighted works are video data, all videos published in a certain time period are obtained from the work publishing platform to form the historical work set; if the copyright works are audio data, all audio released in the time period is obtained from the work release platform to form a historical work set; and if the copyright works are image data, all images released in the time period are acquired from the work releasing platform to form a historical work set. The block link points can adopt a similarity algorithm to calculate the similarity between the copyrighted work and each historical work in the historical work set, and the historical works with the similarity larger than a similarity threshold value are used as the similar works of the copyrighted work. If the distributor of the similar works is the copyright person of the copyright works, the similar works do not constitute infringement; if the publisher of the similar works is not the copyright owner of the copyright works, the similar works are determined to be plagiarism works, namely the similar works can be determined to be an infringement state, the block link points can generate infringement prompt information, and the infringement prompt information is sent to the terminal equipment corresponding to the publisher of the similar works. It should be understood that when the copyrighted work is of different data types, different similarity calculation modes can be adopted, for example, when the copyrighted work is image data, the similarity between the copyrighted work and the historical work can be calculated through a perceptual hash algorithm, a corresponding character string is generated for the copyrighted work according to a certain rule (the rule here can be determined by the hash algorithm), the character strings between the copyrighted work and the historical work are compared, and the closer the result is, the higher the similarity is; when the copyrighted work is text data, the Similarity between the copyrighted work and the historical work can be determined according to a keyword matching method, or the copyrighted work is mapped to a vector space, and the Similarity is calculated by using Cosine Similarity (Cosine Similarity), Euclidean Distance (Euclidean Distance) and other methods, and the like.

Optionally, the block link point may identify works similar to the copyrighted works in the work distribution platform and determine whether the similar works are infringing, and may charge the unauthorized distributors or infringers for copyright fees according to an intelligent contract.

Optionally, the infringement prompt message sent to the publisher at the block link point may include an infringement deadline for the similar works, that is, a deadline for the publisher of the similar works in the infringement state to revoke the similar works from the work distribution platform or pay a copyright fee to the copyright holder. The block chain node can acquire time information, and when the time information exceeds an infringement deadline, similar works are inquired in a work issuing platform; and if the similar works are detected to be in a release state in the work release platform, generating legal documents aiming at the similar works based on the intelligent contract. In other words, when the publisher of the similar works belonging to the infringement state refuses to revoke the similar works from the work publishing platform and refuses to pay the copyright fees to the copyright holders of the copyright works, the block link points generate legal documents after the infringement deadline, and the legal documents can be submitted to the court according to the intelligent contract.

Please refer to fig. 5, which is a schematic diagram of another copyright data processing scenario provided in the embodiment of the present application. As shown in fig. 5, the blockchain node 10a may obtain a historical work set 40b from the work distribution platform 40a, and calculate the similarity between the copyrighted work and each historical work in the historical work set 40b by using a similarity algorithm, to obtain a similarity set 40c between the copyrighted work and the historical work, where the similarity between the copyrighted work and the historical work 1 is: 0.12, the similarity between copyrighted works and historical works 2 is: 0.32, etc. According to the similarity and the publisher information corresponding to the historical works, an infringing work set 40d may be determined from the historical work set 40b, and if the infringing work set 40d may include: historical works 4, historical works 10 and the like, the node 10a can send infringement prompt information to the issuer of the infringed works, namely send the infringement prompt information to the terminal equipment corresponding to the corresponding issuer, so as to remind the issuer to cancel the issuance of the infringed works on the issuing platform, or pay copyright fees to the copyright holders of the copyright works.
