[0075] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0076] An embodiment of the present application provides a method for managing copyright information. This method can be implemented by a computing device, which can be a terminal or a server. Among them, the terminal can be a mobile phone, a tablet computer, a desktop computer, a laptop computer, etc., and the server can be a single server, a server cluster, etc.

[0077] Copyright is the legal ownership of the right to copy computer programs, literary works, music works, photos, games, movies, etc. The copyright owner can be an individual or a company. For practical needs, the copyright owner may change the copyright, and the change methods can include selling, licensing, cooperation, transfer, etc. Among them, selling means that the copyright owner sells its copyright to other individuals or companies. In this case, the original copyright owner no longer has the copyright, and the new owner will have the right to grant licenses or use the content work in other ways. Licensing means that the copyright owner can license its copyright to other individuals or companies. The licensor still retains the copyright, but the licensee can use the content work under the agreed conditions. Cooperation means that the copyright owner can cooperate with others or companies to jointly use the copyright. In this case, the copyright owner may share the copyright with another person or company and share the responsibilities and rights of using, licensing, and obtaining benefits. Transfer means that the copyright owner can transfer a part of the copyright to other individuals or companies, such as transferring the right to use the copyright in a certain region while retaining the right to use the copyright in other regions.

[0078] Currently, after the copyright owner changes the copyright of their content work, a change log is generated. When it is necessary to query the copyright information at a certain point in time later, the change log closest to that time point can be queried first, and the corresponding copyright information can be restored based on the change log. The whole process is relatively cumbersome and the efficiency is very low.

[0079] An embodiment of the present application provides a method for managing copyright information. In this method, when changing the copyright of a target content work, a snapshot of the current latest copyright information of the target content work is first generated. Furthermore, based on this snapshot, the copyright is updated without directly modifying the original copyright information. In addition, after the snapshot is updated, the update time of the snapshot is also recorded. In this way, when querying the copyright information of the target content work at a certain point in time later, the corresponding snapshot can be directly found according to the update time, thus providing an implementation basis for the historical traceability requirements of copyright information.

[0080] The following describes the method for managing copyright information provided by the embodiment of the present application. This method can be implemented by a computing device. Refer to Figure 1 , and the processing flow of this method can include the following steps:

[0081] Step 101, obtain a copyright change instruction for the target content work.

[0082] Among them, the target content work is any content work that needs to maintain copyright information, and can be a computer program, literary work, music work, photo, game, movie, etc.

[0083] In implementation, when a user needs to change the copyright of a target content work, a copyright change instruction for the target content work can be sent to the computing device. Specifically, the copyright change instruction for the target content work can be triggered by the user through the human-computer interaction interface of the terminal and sent to the computing device by the terminal. The copyright change instruction can carry the work identifier of the target content work and change indication information. Among them, the change indication information is used to indicate the update of the copyright information of the target content work to record the specified change operation of the copyright of the target content work. The specified change operation can include sale, authorization, cooperation, transfer, etc.

[0084] For example, if the copyright owner of the target content work is Company A and the change type is to authorize Company B, the change indication information can indicate the update of the copyright information of the target content work to add relevant information about authorizing Company B.

[0085] Step 102, obtain the first updated copyright information of the target content work and generate a snapshot of the first updated copyright information.

[0086] Among them, the first updated copyright information is the latest copyright information of the target content work, which is used to record the latest copyright status of the target content work.

[0087] In implementation, the computing device may store the copyright information corresponding to multiple content works respectively. After receiving the copyright change instruction for the target content work, the computing device obtains the first updated copyright information of the target content work, and this first updated copyright information is the latest copyright information of the target content work.

[0088] Then, the computing device uses the Copy-on-write technology to generate a snapshot of the first updated copyright information, that is, to generate a copy of the first updated version information.

[0089] In addition, it should be noted that if the copyright information of the target content work has not been updated after being entered, then this copyright information is used as the above-mentioned first updated copyright information.

[0090] Step 103: Update the snapshot of the first updated copyright information according to the copyright change instruction to obtain the second updated copyright information.

[0091] In implementation, after the computing device obtains the snapshot of the first updated copyright information, it updates the snapshot according to the change indication information carried in the copyright change instruction to obtain the second updated copyright information.

[0092] For example, if the change indication information is used to indicate that the copyright of the target content work is licensed to Company B, then relevant information can be added to the snapshot, and the relevant information is used to record that the copyright of the target content work is licensed to Company B.

[0093] Step 104: Use the second updated copyright information as the latest copyright information of the target content work, and store the second updated copyright information and the first update time correspondingly.

[0094] In implementation, after updating the snapshot of the first updated copyright information to obtain the second updated copyright information, the second updated copyright information and the first update time can be stored correspondingly. Among them, the first update time can be the time point when the snapshot of the first updated copyright information is updated, which can be accurate to hours, minutes or seconds, and this is not limited in the embodiments of the present application. See Table 1 below, which shows the corresponding relationship between the copyright information and the update time of the content work:

[0095] Table 1

[0096]

[0097]

[0098] Among them, the updated copyright information 1 is the initial copyright information of the content work, T1 is the generation time of the initial copyright information, the updated copyright information 2 is the copyright information obtained after updating the snapshot of the updated copyright information 1, T2 is the time point when the snapshot update of the updated copyright information 1 is completed, the updated copyright information 3 is the copyright information obtained after updating the snapshot of the updated copyright information 3, and T3 is the time point when the snapshot update of the updated copyright information 2 is completed.

[0099] In a possible implementation, it is also possible to query the copyright information of the target content work at a specified time point. Correspondingly, see Figure 2 , and the processing may include the following steps:

[0100] Step 201, receive the first copyright query request for the target content work sent by the terminal.

[0101] Among them, the work identifier of the target content work and the first time point are carried in the first copyright query request.

[0102] In implementation, when the user needs to query the copyright information of the target content work at the first time point, the user can send the first copyright query request for the target content work to the computing device through the terminal. The work identifier of the target content work and the first time point can be carried in the first copyright query request.

[0103] Step 202, determine the second update time that is the closest to the first time point before the first time point among the update times corresponding to the updated copyright information of the target content work.

[0104] In implementation, after receiving the first copyright query request, query the second update time that is the closest to the first time point before the first time point among the update times corresponding to the updated copyright information of the target content work. The following is an example for illustration:

[0105] For example, the corresponding relationship between the updated copyright information and the update time of the target content work is shown in Table 2 below.

[0106] Table 2

[0107] Copyright Information Update Time Update Copyright Information 11 January 12, 2024, 09:25 Update Copyright Information 22 July 10, 2024, 11:23 Update Copyright Information 33 October 25, 2024, 14:12 …… ……

[0108] If the first time point carried in the received first copyright query request is August 1, 2024, then by querying Table 2 above, the second update time 11:23 on July 10, 2024, which is the closest to the first time point before the first time point, can be determined.

[0109] Step 203, obtain the third updated copyright information corresponding to the second update time in the updated copyright information of the target content work.

[0110] In implementation, in combination with the example in step 202 above, the third updated copyright information can be queried as updated copyright information 22.

[0111] Step 204, send the third updated copyright information to the terminal.

[0112] In implementation, after the terminal receives the third updated copyright information, it can visually display the relevant content of the third updated copyright information on the display screen.

[0113] In a possible implementation, it is also possible to generate a snapshot identifier for each generated snapshot. Correspondingly, the processing can be as follows:

[0114] After the snapshot of the first updated copyright information is updated to obtain the second updated copyright information, a first snapshot identifier of the second updated copyright information can be generated, and the second updated copyright information, the first snapshot identifier, and the first update time are stored correspondingly. The snapshot identifier can be an incrementing numerical value. See Table 3 below, which shows the corresponding relationship between the copyright information, snapshot identifier, and update time of the content work.

[0115] Table 3

[0116] Copyright Information Update Time Snapshot ID Update Copyright Information 1 T1 0 Update Copyright Information 2 T2 1 Update Copyright Information 3 T3 2 …… …… ……

[0117] Among them, updated copyright information 1 is the initial copyright information of the content work, T1 is the generation time of the initial copyright information, "0" is the snapshot identifier of the initial copyright information; updated copyright information 2 is the copyright information obtained after updating the snapshot of updated copyright information 1, T2 is the time point when the snapshot update of updated copyright information 1 is completed, "1" is the snapshot identifier of updated copyright information 2; updated copyright information 3 is the copyright information obtained after updating the snapshot of updated copyright information 3, T3 is the time point when the snapshot update of updated copyright information 2 is completed, "2" is the snapshot identifier of updated copyright information 3, and so on.

[0118] In addition, the snapshot identifier can also be obtained by performing a hash operation on the corresponding copyright information. For example, a hash operation is performed on the second updated copyright information to obtain the first snapshot identifier of the second updated copyright information.

[0119] The above are only several forms of snapshot identifiers given as examples, and the embodiments of the present application do not limit the specific form of the snapshot identifier.

[0120] In a possible implementation, it is possible to query the copyright information of the target content work at a specified time point based on the snapshot identifier. Correspondingly, as Figure 3 shown, the processing can include the following steps:

[0121] Step 301, receive a second copyright query request for the target content work sent by the terminal.

[0122] Among them, a second snapshot identifier is carried in the second copyright query request.

[0123] In implementation, when a user needs to query the copyright information of a target content work at a certain time point, the user can send a second copyright query request for the target content work to the computing device through a terminal. The work identifier of the target content work and the second snapshot identifier can be carried in the first copyright query request.

[0124] Step 302: Update the copyright information of the target content work, and obtain the fourth updated copyright information corresponding to the second snapshot identifier.

[0125] In implementation, the computing device can query the correspondence between the updated copyright information of the target content work and the snapshot identifier, and determine the fourth updated copyright information corresponding to the second snapshot identifier.

[0126] Step 303: Send the fourth updated copyright information to the terminal.

[0127] In implementation, after receiving the fourth updated copyright information, the terminal can visually display the relevant content of the fourth updated copyright information on the display screen.

[0128] In another possible implementation, for each updated version information, an update time and an expiration time can be set. Correspondingly, the processing can be as follows:

[0129] After updating the snapshot of the first updated version information to generate the second updated version information, the first update time of the second updated version information can be used as the first expiration time corresponding to the first updated copyright information.

[0130] Based on Table 1 above, after introducing the expiration time, the following Table 4 can be obtained:

[0131] Table 4

[0132] Copyright Information Update Time Expiration Time Update Copyright Information 1 T1 T2 Update Copyright Information 2 T2 T3 Update Copyright Information 3 T3 T4 …… …… ……

[0133] For example, T2 among them is the update time of the updated version information 2 and also the expiration time of the updated version information 1.

[0134] The following is illustrated by an example:

[0135] See Figure 4, at time T123, the version information X of a certain content work was entered, and the entry time was used as the update time, and the expiration time was empty at this time. At time T135, the snapshot of version information X was updated to obtain copyright information Y, and the time point when the update was completed was used as the update time of copyright information Y and the expiration time of copyright information X. At time T158, the snapshot of version information Y was updated to obtain copyright information Z, and the time point when the update was completed was used as the update time of copyright information Z and the expiration time of copyright information Y.

[0136] In addition, the user can also send a copyright deletion instruction for the target content work to the computing device. In this case, the time point when the copyright deletion instruction is received can be used as the expiration time of the latest copyright information of the target content work. See Figure 4 , at time T567, a copyright deletion instruction for the content work was received, and the time point when the instruction was received was used as the expiration time corresponding to copyright information Z.

[0137] In a possible implementation, the update time and the expiration time can be combined to query the copyright information of the target content work at a specified time point. Correspondingly, as Figure 5 shown, this process can include the following steps:

[0138] Step 501, receive a third copyright query request for the target content work sent by the terminal.

[0139] Among them, the work identifier of the target content work and the second time point are carried in the third copyright query request.

[0140] In implementation, when the user needs to query the copyright information of the target content work at the second time point, the user can send a third copyright query request for the target content work to the computing device through the terminal. The work identifier of the target content work and the second time point can be carried in the third copyright query request.

[0141] Step 502, in the updated copyright information of the target content work, determine the fifth updated copyright information whose corresponding update time is before the second time point and whose corresponding expiration time is after the second time point.

[0142] In implementation, after receiving the third copyright query request, in the corresponding relationship among the updated copyright information, update time, and expiration time of the target content work, query the fifth updated copyright information whose corresponding update time is before the second time point and whose corresponding expiration time is after the second time point. The following is an example for illustration:

[0143] For example, the corresponding relationship among the updated copyright information, update time, and expiration time of the target content work is shown in Table 5 below,

[0144] Table 5

[0145]

[0146] If the second time point carried in the received third copyright query request is June 1, 2024, then by querying Table 5 above, it can be found that the second time point is between the update time and the expiration time of the updated copyright information 11.

[0147] Step 503: Send the fifth updated copyright information to the terminal.

[0148] In implementation, after the terminal receives the fifth updated copyright information, it can visually display the relevant content of the fifth updated copyright information on the display screen.

[0149] In another possible implementation, the user can query the copyright life cycle of the target content work. Correspondingly, referring to Figure 6 , this process may include the following steps:

[0150] Step 601: Receive the copyright life cycle query request for the target content work sent by the terminal.

[0151] Among them, the work identifier of the target content work is carried in the copyright life cycle query request.

[0152] In implementation, when the user needs to know the copyright life cycle of the target content work, the user can send a copyright life cycle query request for the target content work to the computing device through the terminal, and the work identifier of the target content work is carried in the copyright life cycle query request.

[0153] Step 602: Obtain all the updated copyright information of the target content work and the corresponding update times.

[0154] In implementation, after receiving the copyright life cycle query request for the target content work, the computing device queries out all the updated copyright information of the target content work and the corresponding update times.

[0155] Step 603: Send all the updated copyright information of the target content work and the corresponding update times to the terminal.

[0156] In implementation, after the terminal receives all the updated copyright information of the target content work and the corresponding update times, it can be visually displayed on the monitor.

[0157] The embodiments of the present application provide a method for managing copyright information. In this method, when the copyright of the target content work is changed, a snapshot of the current latest copyright information of the target content work is first generated. Then, based on this snapshot, the copyright is updated, rather than directly modifying the original copyright information. In addition, after the snapshot is updated, the update time of the snapshot is also recorded. In this way, when querying the copyright information of the target content work at a certain time point later, the corresponding snapshot can be directly found according to the update time, thus providing a basis for realizing the historical traceability requirement of the copyright information.

[0158] Based on the same technical concept, the embodiments of the present application further provide a device for the method of managing copyright information.
