Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a US national application of International Application No. PCT/CN 2019/073378, filed on Jan. 28, 2019, which is based upon and claims priority to Chinese Patent Application No. 201810662615.9, filed on Jun. 25, 2018, the entire contents of which are incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to blockchain network technologies, for example, to a post-processing method and apparatus based on copyright registration information, a device, and a medium. 
     BACKGROUND 
     After an author creates original works such as written works, oral works, musical works, comedic works, quyi works, dance works, acrobatic works, fine arts works, photography works, engineering design drawings, product design drawings, maps, schematic drawings, model works, architectural works and film works, etc., the author generally needs to register and confirm the copyright of his/her works at the first time, and then use them publicly. 
     After the copyright registration and confirmation, in addition to the author&#39;s own use, transaction operations such as copyright assignment and permission may generally be involved, or there may be illegal use without the permission of the author, the author needs to protect his/her rights based on copyright registration information, that is, there may be many post-processing operation requirements based on the copyright registration information. 
     Among the copyright transaction and protection solutions, some are performed offline, and some are performed online. The offline solution, i.e., private negotiation between both parties, has relatively transparent negotiation content, but it is obviously inefficiency, and especially in the Internet era, there is a large amount of original information on the Internet, it is sometimes difficult to obtain information of the author, and one by one negotiation is also time-consuming. The online solution, i.e., post-processing operations performed by an Internet service platform, has the problem that the post-processing operation is transparent, for example, the transaction price is not in public, and the rights protection evidence is difficult to confirm.

     DETAILED DESCRIPTION 
     The present disclosure will be described in detail below with reference to the accompanying drawings and the embodiments. It should be understood that, the specific embodiments described herein are only used to explain the present disclosure rather than to limit the present disclosure. In addition, it should also be noted that, for convenience of description, only part but not all structures related to the present disclosure are illustrated in the accompanying drawings. 
     Embodiment 1 
       FIG. 1  is a flow chart of a post-processing method based on copyright registration information according to Embodiment 1 of the present disclosure. The embodiment may be applicable to post-processing operations of copyright registration information such as copyright transaction and copyright protection, and may be particularly to the scenes where the post-processing operation such as the copyright transaction and the copyright protection are not public, and processing efficiency and credibility are low. The entire post-processing method based on the copyright registration information may generally be executed in cooperation with a copyright service platform and a blockchain system. The blockchain may be a public chain or an alliance chain. The copyright service platform may be a server platform specially used for a user to register copyright information. Alternatively, the copyright service platform may be a totem platform that can interact with nodes and clients in the blockchain network. Correspondingly, the copyright registration information may be image copyright registration information. The solution according to embodiments of the present disclosure may be applied to the copyright service platform. The method may be executed by a post-processing apparatus based on copyright registration information according to embodiments of the present disclosure. The apparatus may be implemented in the form of software and/or hardware. Referring to  FIG. 1 , the method includes the following acts. 
     At block S 110 , copyright registration information is obtained. 
     The copyright registration information refers to information configured to prove the copyright author&#39;s ownership for the copyright registration content. Alternatively, the copyright registration information may include encrypted copyright author information and copyright content abstract; or the encrypted copyright author information, the copyright content abstract and trusted timestamp information. 
     The encrypted copyright author information is generated by encrypting creator information input by the user. The copyright author information includes but is not limited to: name, ID (identity) card, passport, organization name, organization certificate number, etc. The copyright content abstract is generated by performing abstract extraction on the copyright content. The trusted timestamp information refers to a timestamp file configured to represent that the copyright author owns the copyright of the copyright content. 
     The copyright registration information may also include: the encrypted copyright author information, the copyright content abstract, the trusted timestamp information and copyright content description information. The copyright content description information refers to the overall description or the summary of central idea of the creative content, which is optional content. 
     In detail, the copyright service platform may obtain, based on the blockchain address and the block number of the copyright registration information stored in the copyright service platform and required for post-processing operation, the copyright registration information from the blockchain network, and the copyright service platform may also obtain the copyright registration information from the client configured in the copyright service platform through the user input. 
     At block S 120 , at least two participant information and post-processing information of a copyright post-processing operation are obtained based on the copyright registration information. 
     The copyright post-processing operation refers to the operation performed by the copyright author after copyright registration and confirmation. The copyright post-processing operation may include copyright transaction operations such as copyright assignment and permission, and may also include copyright protection operations and other operations. The participant information may include but is not limited to: the name, the ID card, the passport, the organization name, the organization certificate number, etc. The post-processing information is information of the copyright post-processing operation. Exemplarily, different copyright post-processing operations correspond to different post-processing information. 
     When the copyright post-processing operation is the copyright protection operation, the post-processing information of the copyright post-processing operation is copyright protection information. Alternatively, obtaining the at least two participant information and the post-processing information of the copyright post-processing operation based on the copyright registration information may include acts of: obtaining copyright holder information, copyright infringer information and infringement evidence information of the copyright protection operation based on the copyright registration information. The copyright holder is the copyright author. Correspondingly, the copyright infringer refers to the party illegally using the copyright content of the copyright author without the permission of the copyright author. The infringement evidence information may include the infringement time, the infringement content and the infringement evidence website address, etc. 
     In detail, when the copyright service platform receives that any user submits a work to be protected through the copyright service platform or a client interface (such as a browser interface or an application interface on the client) and initiates a copyright protection request, the copyright service platform may obtain the copyright registration information from the blockchain network based on the information of the work to be protected and the address stored in the blockchain, determine the copyright holder information based on the copyright registration information, determine the infringement evidence information by performing operations such as webpage crawling, recognition matching, user confirmation based on the copyright registration information, and determine the copyright infringer information based on the infringement evidence information. 
     When the copyright post-processing operation is the copyright transaction operation, the post-processing information of the copyright post-processing operation may be the copyright transaction information. Alternatively, obtaining the at least two participant information and the post-processing information of the copyright post-processing operation based on the copyright registration information may include acts of: obtaining purchaser information, seller information and transaction processing information of a copyright transaction processing based on the copyright registration information. The transaction processing information may include transaction object information, transaction time information, and transaction amount information. The seller is the copyright author. Correspondingly, the purchaser is the party who purchases the copyright content or the copyright of the copyright author. The transaction object information refers to the information of the trading work. 
     In detail, when there is a transaction between the copyright author and the purchaser who needs to use or to purchase the work, a transaction request including the information of the work to be traded may be initiated to the copyright service platform. After the transaction request is received, the copyright service platform may obtain the copyright registration information of the work to be traded from the blockchain network based on the information of the work to be traded and the address stored in the blockchain, determine the seller information based on the copyright registration information, and determine the purchaser information and the transaction processing information based on the transaction request of the information of the work to be traded and the copyright registration information. 
     It should be noted that, the copyright transaction operation may also be organized by the copyright service platform. In detail, the copyright service platform may display the information of the work to be traded to the user, and use advanced intelligent image recognition technologies such as accurate image understanding, graphic understanding to intelligently understand, recognize, and automatically generate labels, thereby facilitating the user to query the target image. When the copyright service platform detects that the user purchases any work that can be traded, it may obtain the copyright registration information from the blockchain network based on the information of the work and the address stored in the blockchain, and determine the seller information, the purchaser information and the transaction processing information based on the copyright registration information. 
     At block S 130 , the at least two participant information and the post-processing information are sent as a transaction request into a blockchain network to request to add into a block for storage. 
     In detail, the copyright service platform may perform corresponding processing such as encryption on the at least two participant information and the post-processing information as the transaction request, and transmit the transaction request to the blockchain network to instruct indicating a block generation node in the blockchain network to store the transaction request in the blockchain. 
     Exemplarily, different copyright post-processing operations may have different ways of determining the transaction request, and there may also be different ways of determining the transaction request for the same copyright post-processing operation. Following embodiments may describe several methods for determining the transaction request based on the copyright transaction information and the copyright protection information, and sending the transaction request in the blockchain network to request to add into the block for storage. 
     With the technical solution according to embodiments of the present disclosure, the copyright service platform sends the information of the copyright post-processing operation as the transaction request into the blockchain network for storage, such that the information of the copyright post-processing operation is transparent to the copyright service platform and the trading parties, and cannot be tampered with, thereby weakening the power of the copyright service center, and ensuring the credibility, accuracy and transparency of the information of the copyright post-processing operation. In addition, since the information of the copyright post-processing operation maintains its credibility through the blockchain technology, it may better use Internet resources, and simplify the process of the post-processing operation, thereby improving the processing efficiency of the post-processing of the copyright registration information. 
     Embodiment 2 
       FIG. 2  is a flow chart of a post-processing method based on copyright registration information according to Embodiment 2 of the present disclosure. On the basis of the above embodiments, the embodiments make further description for obtaining copyright holder information, copyright infringer information and infringement evidence information of a copyright protection operation based on the copyright registration information when the copyright post-processing operation is the copyright protection operation. Referring to  FIG. 2 , the method includes the following acts. 
     At block S 210 , copyright registration information is obtained. 
     At block S 220 , webpage crawling is performed through the Internet. 
     In detail, when the copyright service platform receives that any user submits a work to be protected through the copyright service platform or the client interface (such as a browser interface or an application interface on the client) and initiates a copyright protection request, the copyright service platform may recognize the work to be protected based on intelligent image recognition and other functions, determine the crawling target based on the recognition result, and crawl the webpage on the Internet according to the crawling target. 
     At block S 230 , the webpage crawled is matched to content of a copyright registration object corresponding to the copyright registration information, to recognize a suspected infringing webpage, and a snapshot or a website of the suspected infringing webpage is taken as the infringement evidence information. 
     The snapshot is a quick way to read all content, including the website URL of the current webpage, included in the current webpage. 
     In detail, content in the crawled webpage is matched to the content of the copyright registration object corresponding to the copyright registration information. The crawled webpage is determined as the suspected infringing webpage, when the match is successful or the matching degree reaches a preset threshold value such as 80%. In order to reduce the probability of fraud on the copyright service platform and to improve authenticity and reliability of the evidence, the copyright service platform may take the snapshot of the suspected infringing webpage or the website of the webpage as the infringement evidence information, such that the block generation node may, based on the website of the webpage or the website included in the snapshot, access the network to intercept the webpage, and retain it as the evidence, thereby ensuring that the evidence stored in the blockchain is actually available from the Internet. 
     At block S 240 , publisher information of the suspected infringing webpage is extracted as the copyright infringer information, and the copyright holder information is determined based on the copyright registration information. 
     The publisher refers to a user who publishes relevant content on the webpage. The publisher of the suspected infringing webpage is a user who publishes a content highly similar to the copyright registration object of the copyright author on the webpage. 
     In detail, after the suspected infringing webpage included in the Internet is identified through webpage crawling, and the website of the webpage is determined as the infringement evidence information, the copyright service platform may obtain publisher account information of the infringing content included in the webpage based on the suspected infringing webpage, and obtain the publisher information based on the publisher account information, and determine the publisher information as the copyright infringer information. Moreover, the information of the copyright author is determined as the copyright holder information based on the obtained copyright registration information. 
     At block S 250 , the copyright holder information, the copyright infringer information, and the infringement evidence information are sent as the transaction request into the blockchain network to request to add into the block for storage. 
     In detail, the copyright service platform may processes the copyright protection information, i.e., the copyright holder information and the copyright infringer information, and the infringement evidence information, and transmits it as the transaction request to the blockchain network to instruct the block generation node in the blockchain network to store the transaction request in the blockchain. 
     Exemplarily, sending the copyright holder information, the copyright infringer information, and the infringement evidence information as the transaction request into the blockchain network to request to add into the block for storage includes acts of: adding the copyright holder information, the copyright infringer information and the infringement evidence information to a first intelligent contract as the transaction request, and sending the transaction request into the blockchain network. The infringement evidence information is the website, and the first intelligent contract is configured to request the block generation node to obtain the suspected infringing webpage from the Internet based on the website, and add the suspected infringing webpage into the block for storage. 
     The first intelligent contract includes executable code segments configured to control the functions executable by the block generation node. 
     In detail, the copyright service platform adds the copyright protection information to the first intelligent contract as the transaction request, and sends the transaction request into the blockchain network. After the block generation node in the blockchain network receives the transaction request, it may, based on the website in the first intelligent contract, access the network to intercept the webpage, and store the webpage intercepted in the blockchain as the infringement evidence information. 
     With the technical solution according to embodiments of the present disclosure, the copyright protection information is sent as the transaction request to the blockchain network for storage, such that the copyright protection information is transparent to the copyright service platform, the copyright infringer and the copyright holder, and may not be tampered with, thereby weakening the power of the copyright service center, and ensuring the credibility, accuracy and transparency of the copyright protection information. In addition, since the copyright protection information is implemented based on the blockchain technology, problems that the copyright protection evidence is difficult to obtain and the authenticity is difficult to guarantee can be solved, and the process of the post copyright protection can be simplified, thereby improving the processing efficiency of the copyright protection operation. 
     Embodiment 3 
       FIG. 3  is a flow chart of a post-processing method based on copyright registration information according to Embodiment 3 of the present disclosure. On the basis of the above embodiments, the embodiments make further description for sending the participant information and the post-processing information as the transaction request into the blockchain network to request to add into the block for storage when the copyright post-processing operation is a copyright transaction operation. Referring to  FIG. 3 , the method includes the following acts. 
     At block S 310 , copyright registration information is obtained. 
     At block S 320 , at least two participant information and post-processing information of the copyright post-processing operation are obtained, based on the copyright registration information. 
     At block S 330 , part or all of the at least two participant information and the post-processing information are encrypted with a public key set by the copyright service platform, the part or all of the at least two participant information and the post-processing information encrypted are sent as the transaction request into the blockchain network to request to add into the block for storage. 
     The participant information is the purchaser information and the seller information. The post-processing information is transaction processing information. The transaction processing information may include transaction object information, transaction time information, and transaction amount information. 
     In detail, due to the openness and transparency of the blockchain record information, in order to protect the security of copyright transaction information, the copyright service platform may encrypt part or all of the purchaser information, the seller information and the transaction processing information such as the transaction amount information, with the public key in an asymmetric key pair randomly generated or fixedly set by the copyright service platform, and transmit the encryption result as the transaction request into the blockchain network, such that the block generation node in the blockchain network stores the transaction request in the blockchain. 
     At block S 340 , a private key corresponding to the public key is fed back to a participant. 
     Since the asymmetric encryption public key and the asymmetric encryption private key appear in pairs, when the asymmetric encryption public key is used for encryption, the asymmetric encryption private key needs to be used for decryption. Therefore, in order to enable the participant to query the information involved in the copyright transaction operation, the copyright service platform needs to feed back the private key corresponding to the public key to the participant after the copyright service platform encrypts part or all of the participant information and the post-processing information with the public key set by the copyright service platform. 
     Exemplarily, when there are other users who have the right to query the information, the copyright service platform may also feed back the private key corresponding to the public key to the user who has the permission. 
     With the technical solution according to embodiments of the present disclosure, the copyright service platform encrypts, with the public key set by the copyright service platform, the copyright transaction information as the transaction request, and sends the transaction request to the blockchain network for storage, such that the copyright transaction information is transparent to the copyright service platform and the trading parties, and may not be tampered with, thereby weakening power of the copyright service center and ensuring the credibility, accuracy and transparency of the copyright transaction information. 
     In order to further ensure the security of the information of both parties involved in the transaction, the copyright service platform may also encrypt the part or all of the participant information and the post-processing information by using a public key provided by the participant. Exemplarily, sending the participant information and the post-processing information as the transaction request into the blockchain network to request to add into the block for storage includes acts of: encrypting part or all of the participant information and the post-processing information with a public key provided by at least one participant; and sending the part or all of the participant information and the post-processing information encrypted as the transaction request into the blockchain network to request to add into the block for storage. 
     In detail, the copyright service platform may send a public key providing message to the participants, i.e., the purchaser and the seller, to cause the purchaser and the seller to respectively provide his/her public key in the asymmetric key pair to the copyright service platform. The copyright service platform may use the public key of the purchaser and/or the seller to encrypt part or all of the participant information and the post-processing information, and send the encrypted result as the transaction request into the blockchain network for storage. 
     It is possible to encrypt part or all of the participant information and the post-processing information by using the public keys of the purchaser and the seller, respectively, to form two encrypted information, and the two encrypted information may be sent as two different transaction requests into the blockchain network for storage, to allow different users having the permissions to inquire and learn. 
     It is also possible to encrypt part of the participant information and the post-processing information or encrypt different parts of all the information by using the public keys of the purchaser and the seller. For example, the participant information may be encrypted by using the public key of the purchaser, and part or all of the post-processing information may be encrypted by using the public key of the seller. 
     Correspondingly, since the copyright transaction information is encrypted by using the public key of the purchaser and/or the seller, any user or the copyright service platform can view the encrypted information only when one or two of the purchaser and/or the seller agree and provide the private key, which ensures the privacy of both parties and the security of transaction information. 
     With the technical solution according to embodiments of the present disclosure, the copyright service platform encrypts the copyright transaction information by using the public key of the participants as the transaction request, the security of the information of both trading parities can be furthered ensured, and by sending the transaction request into the blockchain network for storage, such that the copyright transaction information is transparent to the copyright service platform and both parties of the transaction, and may not be tampered with, thereby weakening the power of the copyright service center and ensuring the credibility, accuracy and transparency of the copyright transaction information. 
     Embodiment 4 
       FIG. 4  is a flow chart of a post-processing method based on copyright registration information according to Embodiment 4 of the present disclosure. On the basis of the above embodiments, the embodiments also provide a method for sending the participant information and the post-processing information as the transaction request into the blockchain network to request to add into the block for storage when the copyright post-processing operation is the copyright transaction operation. Referring to  FIG. 4 , the method includes the following acts. 
     At block S 410 , copyright registration information is obtained. 
     At block S 420 , at least two participant information and post-processing information of copyright post-processing operation are obtained, based on the copyright registration information. 
     At block S 430 , the participant information and the post-processing information are added to a second intelligent contract as the transaction request, and the transaction request is sent into the blockchain network. 
     The second intelligent contract is configured to request the block generation node to generate an asymmetric key pair, and encrypt part or all of the participant information and the post-processing information by using a public key. The participant information is the purchaser information and the seller information. The post-processing information is the transaction processing information. The transaction processing information may include the transaction object information, the transaction time information, and the transaction amount information. 
     In detail, in order to further improve the credibility of transaction information processing, and improve the efficiency of the copyright post-processing operation, the copyright service platform may directly add the copyright transaction information, i.e., the purchaser information and the seller information, and the transaction processing information, to the second intelligent contract as the transaction request, and transmit the transaction request to the blockchain network, such that the block generation node automatically generates the asymmetric key pair based on executable codes of the second intelligent contract in the transaction request, and encrypts the part or all of the participant information and the post-processing information with the public key. 
     At block S 440 , a private key fed back by the block generation node to the copyright service platform or the participant is received. 
     In detail, the copyright service platform may receive the private key fed back by the block generation node to the user having the permission such as the purchaser and the seller, and forward the private key to the corresponding user. 
     With the technical solution according to embodiments of the present disclosure, the copyright service platform directly adds the copyright transaction information to the second intelligent contract, such that the block generation node generates the asymmetric key pair based on the rule of the second intelligent contract, and encrypts the copyright transaction information by using the public key, and stores it. Thus, the credibility of the copyright transaction information can be improved, and the efficiency of the post copyright transaction operation can be improved. Moreover, the power of the copyright service center can be weakened, and the credibility, accuracy and transparency of the copyright transaction information can be ensured. 
     Exemplarily, sending the participant information and the post-processing information as the transaction request into the blockchain network to request to add into the block for storage may also include acts of: adding the participant information and the post-processing information to a third intelligent contract as the transaction request, and sending the transaction request into the blockchain network; receiving the private key providing message fed back by the block generation node, informing a participant to provide an asymmetric key pair based on the private key providing message, and forwarding the asymmetric key to the block generation node, to request the block generation node to encrypt part or all of the at least two participant information and the post-processing information based on a public key of the asymmetric key pair. 
     The third intelligent contract is configured to request the block generation node to feed back the private key providing message. The private key providing message refers to information for indicating the copyright service platform to provide the private key to the block generation node. Alternatively, the private key providing message may include the information of the user that needs to provide the private key, such as the seller information and/or the purchaser information. 
     In detail, the copyright service platform adds the copyright transaction information to the third intelligent contract as the transaction request, and transmits the transaction request to the blockchain network, such that the block generation node feeds back the private key providing message to the copyright service platform based on the rule of the third intelligent contract in the transaction request. After the private key providing message fed back by the block generation node is received, the copyright service platform may inform the corresponding participants to provide the asymmetric key pair based on the information of the participant that needs to provide the asymmetric key pair in the private key providing message, and forwards the asymmetric key pair to the block generation node, such that the block generation node encrypts part or all of the participant information and the post-processing information by using the public key in the asymmetric key pair. 
     With the technical solution according to embodiments of the present disclosure, the copyright service platform directly adds the copyright transaction information to the third intelligent contract, such that the block generation node feeds back the private key providing message to the copyright service platform based on the rule of the third intelligent contract, and encrypts and stores the copyright transaction information by using the public key of the participant fed back by the copyright service platform. Thus, the credibility of the copyright transaction information can be improved, and the efficiency of the post copyright transaction operation can be improved. Moreover, the power of the copyright service center can be weakened, and the credibility, accuracy and transparency of the copyright transaction information can be ensured.

       FIG. 5  is a flow chart of a post-processing method based on copyright registration information according to Embodiment 5 of the present disclosure. On the basis of the above embodiments, the embodiments also provide a method for sending the participant information and the post-processing information as the transaction request into the blockchain network to request to add into the block for storage when the copyright post-processing operation is the copyright transaction operation. Referring to  FIG. 5 , the method may include the following acts. 
     At block  510 , copyright registration information is obtained. 
     At block  520 , at least two participant information and post-processing information of copyright post-processing operation are obtained based on the copyright registration information 
     At block  530 , part or all of the participant information and the post-processing information are signed and encrypted, the part or all of the at least two participant information and the post-processing information signed and encrypted are sent as the transaction request into the blockchain network to request to add into the block for storage. 
     The participant information is the purchaser information and the seller information. The post-processing information is the transaction processing information.
