The method of the embodiment of the application can be executed in user equipment, network equipment or equipment formed by integrating the user equipment and the network equipment through a network. The user equipment comprises but is not limited to various terminal equipment such as a computer, a mobile phone, a tablet computer and the like; including but not limited to implementations such as a network host, a single network server, multiple sets of network servers, or a cloud-computing-based collection of computers. Here, the Cloud is made up of a large number of hosts or web servers based on Cloud Computing (Cloud Computing), which is a virtual computer of distributed Computing that consists of a collection of loosely coupled computers.
Fig. 2 shows a schematic topology of the embodiment of the present application in implementation, where a user uses a user terminal 210 to send a request for recording copyright information to a network device, and a service node 220 is used as a device for executing the method for recording copyright information in the embodiment of the present application, and is configured to execute various processes when recording copyright information. Fig. 3 illustrates a processing flow of a method for recording copyright information according to an embodiment of the present application, where the service node 220 performs at least the following processing steps:
step S301, a copyright information recording request sent by a user is acquired. The copyright information recording request comprises verification information about the content of the works, and is used for verifying the source of the works and the content of the works so as to ensure that the recorded copyright information can be used for judging the attribution of the copyright of the works.
In one embodiment of the present application, the verification information about the content of the work may include content digest information and a digital signature of the content of the work. The content summary information is a hash value obtained after hash calculation is performed on the content of the work, for example, for a software work, the content summary information may be a hash value obtained after the software source code is calculated through a sha256 algorithm or other one-way hash algorithms, and if the software source code is changed, the content summary information is changed, so that the uniqueness of the recorded content of the work can be ensured.
The digital signature is a ciphertext obtained by encrypting the content abstract information through the private key of the user, each user can generate a public key and a private key in a reliable mode and provide the public key for the service node, the private key is used for generating the digital signature when a request is submitted, the service node can decrypt the digital signature through the public key to obtain the content abstract information, and the content abstract information is compared with the content abstract information obtained through Hash calculation, so that the uniqueness of a work source can be ensured.
It should be understood by those skilled in the art that the specific content of the verification information related to the content of the work is only an example, and other existing or future verification information may be applicable to the present invention, and is included in the scope of the present invention and is incorporated by reference herein. For example, the user may also directly provide the original text of the work content in the provided copyright information recording request, that is, the verification information may be the original text and the digital signature of the work content, and the service node performs corresponding hash calculation on the original text of the work content to obtain the content summary information, thereby also realizing verification on the source of the work and the work content.
Step S302, according to the verification information about the work content and the time stamp of the copyright information recording request sent by the user, determining the copyright information to be written into the latest block of the block chain. In determining copyright ownership, the following and other determination factors are needed: the source of the work, the content of the work, and the time of creation of the work, i.e., the copyright ownership of the work can only be determined if it is determined who created what work at what time.
Since the verification information about the content of the work can be used to verify the source of the work and the content of the work, and the user sending a copyright information recording request is more time-efficient than the cumbersome copyright registration procedure, the time stamp of the user sending the copyright information recording request can be used to indicate the creation time of the work. Therefore, the judgment factors required when the copyright attribution is determined can be reflected according to the verification information about the work content and the copyright information determined by the timestamp of the copyright information recording request sent by the user, the information cannot be tampered after the information is written into the block of the block chain, and the copyright of the work can be effectively prevented from being maliciously registered in advance by lawbreakers.
In some embodiments of the present application, copyright information of a plurality of works may be written in each block, and thus when determining copyright information to be written in a latest block of a blockchain, the copyright information to be written in the latest block of the blockchain may be determined according to the verification information about the content of the works, which is obtained in a preset amount or within a preset time, and a timestamp of a copyright information recording request sent by a user. For example, it may be configured that, when 8 copyright information recording requests are received, the copyright information to be written into the latest block of the blockchain is determined based on the received requests, and at this time, the copyright information to be written into the latest block of the blockchain includes the copyright information of 8 works. In addition, it is also possible to determine the copyright information to be written into the latest block of the block chain based on a preset time, for example, after each new block is generated, starting a timer, and determining the copyright information to be written into the latest block of the block chain based on the copyright information record received within 60 seconds, and if 10 pieces of copyright information records are received within 60 seconds, the copyright information to be written into the latest block of the block chain includes the copyright information of 10 works.
Step S303, generating the latest block of the block chain based on the copyright information in the latest block of the block chain to be written. Therefore, a user can submit a copyright information recording request at any time after the creation of the work is finished, the copyright information of the work is required to be recorded, and the time stamp of the copyright information recording request sent by the user is close to the creation time of the work, and the related copyright information is recorded in the block chain and is difficult to tamper, so that the attribution of the copyright of the work can be accurately judged based on the recorded copyright information.
In some embodiments of the present application, before determining the copyright information to be written into the latest block of the blockchain, verification information about the content of the work may be verified, confirming that the verification information was generated by the sending user. Therefore, the source of the work is verified once before the block is generated, so that the problem that other users maliciously falsely use the private key of the actual creator of the work to submit the copyright information recording request to cause the recorded copyright information to be wrong is avoided.
In a practical scenario, the service node may obtain the public key of each user by using a digital signature technology. The verification information about the work content at least comprises the content abstract information and the digital signature of the work content, the digital signature of the work content is decrypted according to the public key of the corresponding user to obtain a decryption result, then judgment is carried out according to the comparison result of the decryption result and the content abstract information of the work content, and if the decryption result and the comparison result are consistent, the verification information can be confirmed to be generated by the sending user.
In some embodiments of the present application, public key digest information may also be included in the copyright information record request submitted by the user as one of the verification information about the content of the work. At this time, when verifying the verification information on the work content, it may be confirmed that the verification information is generated by the sending user, based on a comparison result of the decryption result and the content digest information of the work content, and a verification result of the public key to the public key digest information.
For example, the service node may calculate the public key digest information digest1 by performing hash calculation on the public key of the user, compare the public key digest information digest2 in the received copyright information recording request, and if the verification result shows that digest1 and digest2 are consistent, it indicates that the public key of the user is correct. Thus, the digital signature decrypted based on the public key of the user is also correct, and if the decryption result of the digital signature matches the comparison result of the content digest information of the work content, it indicates that the verification information is indeed generated by the transmitting user. If the verification result is that the digest1 and the digest2 are not consistent, it indicates that the public key on the service node is wrong, and the comparison result between the decryption result of the digital signature and the content digest information of the content of the work is not trusted, and even if the comparison result is consistent, it cannot be confirmed that the verification information is generated by the sending user.
In summary, in order to ensure the most reliable verification, the copyright information to be written into the latest block of the block chain may include the following: public key or public key digest information of the user, a time stamp of the user's transmission copyright information recording request, content digest information of the content of the work, and a digital signature of the content of the work, as shown in fig. 4. The digest information may be hash values generated by various unidirectional hash algorithms.
In order to ensure the reliability of the recorded copyright information at the time of actual deployment, a backup node 230 may be provided in addition to the service node 220. Fig. 5 shows a schematic topology of a scheme in which a backup node is deployed in implementation, where a service node (master node) 220 provides a service to outside, receives a request sent by a user and performs corresponding processing, and after generating a latest block of the block chain, broadcasts the latest block to a backup node 230, so that the backup node updates the block chain according to the latest block. Each backup node has a complete backup of the blockchain, and if the data in the service node is wrong, a correct copy can be easily found from the backup node, so that the accuracy of the data content in the blockchain is ensured.
Based on the same inventive concept, the embodiment of the present application further provides a device for recording copyright information, the corresponding method of the device is the method in the foregoing embodiment, and the principle of solving the problem is similar to the method.
The equipment for recording the copyright information is used for reliably recording the copyright information of the works of the user through the block chain, ensures that the actual creation time of the copyright of the works can be accurately recorded, cannot be tampered, and can effectively avoid the copyright of the works from being maliciously registered in advance by lawbreakers. Fig. 1 shows a schematic diagram of the contents of blocks in a blockchain for recording copyright information in an embodiment of the present application, where each block may contain the following contents:
block size: the size of the whole block can be marked, so that the block positioning and the reading of data in the block are facilitated;
parent block hash: the hash value of all information of the previous block, so that each block can form a chain and be verified one by one until the first block;
time stamping: the time of each block generation;
copyright quantity: the number of copyright information contained in each block;
a single piece of copyright information: information on the determination of copyright attribution for each work.
The device for recording copyright information in the embodiment of the present application may be a user device, a network device, or a device formed by integrating a user device and a network device through a network. The user equipment comprises but is not limited to various terminal equipment such as a computer, a mobile phone, a tablet computer and the like; including but not limited to implementations such as a network host, a single network server, multiple sets of network servers, or a cloud-computing-based collection of computers. Here, the cloud is made up of a large number of hosts or network servers based on cloud computing (cloud computing), which is a virtual computer of distributed computing that consists of a collection of loosely coupled computers.
Fig. 2 shows a schematic topology structure of the embodiment of the present application in implementation, where a user uses a user terminal 210 to send a request for recording copyright information to a network device, and a service node 220 is a device for recording copyright information in this embodiment, and is used to perform various processing when recording copyright information. Fig. 6 is a schematic structural diagram of an apparatus for recording copyright information according to an embodiment of the present application, where the apparatus includes a receiving device 610, a data processing device 620, and a block generating device 630. The receiving device 610 is used for acquiring a copyright information recording request sent by a user. The copyright information recording request comprises verification information about the content of the works, and is used for verifying the source of the works and the content of the works so as to ensure that the recorded copyright information can be used for judging the attribution of the copyright of the works.
In one embodiment of the present application, the verification information about the content of the work may include content digest information and a digital signature of the content of the work. The content summary information is a hash value obtained after hash calculation is performed on the content of the work, for example, for a software work, the content summary information may be a hash value obtained after the software source code is calculated through a sha256 algorithm or other one-way hash algorithms, and if the software source code is changed, the content summary information is changed, so that the uniqueness of the recorded content of the work can be ensured.
The digital signature is a ciphertext obtained by encrypting the content abstract information through the private key of the user, each user can generate a public key and a private key in a reliable mode and provide the public key for the service node, the private key is used for generating the digital signature when a request is submitted, the service node can decrypt the digital signature through the public key to obtain the content abstract information, and the content abstract information is compared with the content abstract information obtained through Hash calculation, so that the uniqueness of a work source can be ensured.
It should be understood by those skilled in the art that the specific content of the verification information related to the content of the work is only an example, and other existing or future verification information may be applicable to the present invention, and is included in the scope of the present invention and is incorporated by reference herein. For example, the user may also directly provide the original text of the work content in the provided copyright information recording request, that is, the verification information may be the original text and the digital signature of the work content, and the service node performs corresponding hash calculation on the original text of the work content to obtain the content summary information, thereby also realizing verification on the source of the work and the work content.
The data processing device 620 is configured to determine the copyright information to be written into the latest block of the block chain according to the verification information about the work content and the time stamp of the copyright information recording request sent by the user. In determining copyright ownership, the following and other determination factors are needed: the source of the work, the content of the work, and the time of creation of the work, i.e., the copyright ownership of the work can only be determined if it is determined who created what work at what time.
Since the verification information about the content of the work can be used to verify the source of the work and the content of the work, and the user sending a copyright information recording request is more time-efficient than the cumbersome copyright registration procedure, the time stamp of the user sending the copyright information recording request can be used to indicate the creation time of the work. Therefore, the judgment factors required when the copyright attribution is determined can be reflected according to the verification information about the work content and the copyright information determined by the timestamp of the copyright information recording request sent by the user, the information cannot be tampered after the information is written into the block of the block chain, and the copyright of the work can be effectively prevented from being maliciously registered in advance by lawbreakers.
In some embodiments of the present application, copyright information of a plurality of works may be written in each tile, and thus when determining copyright information to be written in the latest tile of the blockchain, the data processing apparatus 620 may determine copyright information to be written in the latest tile of the blockchain based on the verification information about the content of the works, which is acquired in a preset number or in a preset time, and a timestamp of a copyright information recording request sent by a user. For example, it may be configured that, when 8 copyright information recording requests are received, the copyright information to be written into the latest block of the blockchain is determined based on the received requests, and at this time, the copyright information to be written into the latest block of the blockchain includes the copyright information of 8 works. In addition, it is also possible to determine the copyright information to be written into the latest block of the block chain based on a preset time, for example, after each new block is generated, starting a timer, and determining the copyright information to be written into the latest block of the block chain based on the copyright information record received within 60 seconds, and if 10 pieces of copyright information records are received within 60 seconds, the copyright information to be written into the latest block of the block chain includes the copyright information of 10 works.
The block generating means 630 is configured to generate the latest block of the block chain based on the copyright information in the latest block of the block chain to be written. Therefore, a user can submit a copyright information recording request at any time after the creation of the work is finished, the copyright information of the work is required to be recorded, and the time stamp of the copyright information recording request sent by the user is close to the creation time of the work, and the related copyright information is recorded in the block chain and is difficult to tamper, so that the attribution of the copyright of the work can be accurately judged based on the recorded copyright information.
In some embodiments of the present application, the data processing device 620 may verify the verification information about the content of the work before determining the copyright information to be written in the latest block of the blockchain, confirming that the verification information was generated by the sending user. Therefore, the source of the work is verified once before the block is generated, so that the problem that other users maliciously falsely use the private key of the actual creator of the work to submit the copyright information recording request to cause the recorded copyright information to be wrong is avoided.
In an actual scenario, a digital signature technology may be utilized, the receiving device of the service node may obtain a public key of each user, at this time, the verification information about the work content at least includes content digest information and a digital signature of the work content, the data processing device 620 first decrypts the digital signature of the work content according to the public key of the corresponding user to obtain a decryption result, then determines according to a comparison result between the decryption result and the content digest information of the work content, and if the two are consistent, may confirm that the verification information is generated by the sending user.
In some embodiments of the present application, public key digest information may also be included in the copyright information record request submitted by the user as one of the verification information about the content of the work. At this time, when verifying the verification information on the work content, it may be confirmed that the verification information is generated by the sending user, based on a comparison result of the decryption result and the content digest information of the work content, and a verification result of the public key to the public key digest information.
For example, the data processing apparatus of the service node may calculate the public key digest information digest1 by performing hash calculation on the public key of the user, compare the public key digest information digest2 in the received copyright information recording request, and if the verification result shows that the public key of the user is correct, the data processing apparatus of the service node indicates that the public key of the user is identical to the public key of the digest1 and the public key of the digest 2. Thus, the digital signature decrypted based on the public key of the user is also correct, and if the decryption result of the digital signature matches the comparison result of the content digest information of the work content, it indicates that the verification information is indeed generated by the transmitting user. If the verification result is that the digest1 and the digest2 are not consistent, it indicates that the public key on the service node is wrong, and the comparison result between the decryption result of the digital signature and the content digest information of the content of the work is not trusted, and even if the comparison result is consistent, it cannot be confirmed that the verification information is generated by the sending user.
In summary, in order to ensure the most reliable verification, the copyright information to be written into the latest block of the block chain may include the following: public key or public key digest information of the user, a time stamp of the user's transmission copyright information recording request, content digest information of the content of the work, and a digital signature of the content of the work, as shown in fig. 4.
In order to ensure the reliability of the recorded copyright information at the time of actual deployment, a backup node 230 may be provided in addition to the service node 220. At this time, the device corresponding to the service node may further include a sending device, configured to send data to the backup node. Fig. 5 shows a schematic topology of a scheme in which a backup node is deployed in implementation, where a service node (master node) 220 provides a service to outside, receives a request sent by a user and performs corresponding processing, and after generating a latest block of the block chain, its sending device is used to broadcast the latest block to a backup node 230, so that the backup node updates the block chain according to the latest block. Each backup node has a complete backup of the blockchain, and if the data in the service node is wrong, a correct copy can be easily found from the backup node, so that the accuracy of the data content in the blockchain is ensured.
