A method for managing copyrights of content is disclosed. The method for managing copyrights of content of the present invention comprises: a step in which a server for managing copyrights of content receives first content from a user terminal; a step in which the server extracts unique information of the first content; a step in which the server searches for second content that at least partially matches or is similar to the first content by using the unique information of the first content; and a step in which, if the second content is retrieved, information on copyright usage and profit of the second content is provided to the user terminal.

Description

How to manage copyright of content

The present invention relates to a method for managing copyrights of contents, and more particularly, to a method for managing copyrights for secondary works by using unique information of contents.

Recently, as content production technology has become widely distributed to the general public, and the Internet environment in which it can be distributed has developed, the single-person media market in which individuals directly produce and distribute content has grown significantly. The single-person media market has developed to realize monetization by providing content for a fee or attracting paid advertisements, rather than simply sharing content in terms of hobbies. In such a situation, problems such as copyright infringement of content have become a major problem.

Some major content distribution platforms have their own copyright management system, introducing a function to block uploading and distribution of content suspected of infringing copyright by others. However, such a copyright management system has a block that blocks the use of some or all of the work of others as it is, but there is a limit to blocking the secondary work that partially transforms and edits it.

In recent years, as the editing technology of sound sources and images has developed and such technology is widely distributed to the public, it has become easier to produce secondary works. And as content consumers' tastes diversify, consumption of such secondary works is increasing. However, there is no system for requesting permission or distributing profits even though the use of such secondary works requires permission from the primary author.

Therefore, there is an increasing demand for a management method capable of determining whether or not a secondary work is a secondary work in an efficient and highly accurate method, and performing profit management according to the work.

Hereinafter, a method for managing copyright of content according to an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The content copyright management method may be performed through the server 100 connected to the Internet through a network. The content copyright management method of the present invention may be performed by one single server device, and in some cases, each step may be performed separately or cooperatively by two or more server devices. For convenience of explanation, the following description is based on what is performed by one server device 100. However, it does not exclude that each step is performed separately or cooperatively by two or more server devices.

Referring to FIG. 1, the server 100 performing the copyright management method of the present invention may be connected to the user terminal 200 through a network. A plurality of user terminals 200 may exist and may be connected to the server 100 through a network, respectively.

The server 100 may include a communication unit 110, a unique information extraction unit 120, a search unit 130, a determination unit 140, a copyright information database 150, and a unique information database 160. Each configuration of the above-described server 100 will be described in detail while describing each step below.

Referring to FIG. 2, the method for managing copyright of content of the present invention includes receiving a first content (S100), extracting unique information of the first content (S200), and searching for a second content (S300). , Determining whether the first content is a secondary work of the second content (S400), providing copyright usage and profit information of the second content (S500), dividing the first content revenue into the first and second content contributions And storing the unique information of the first content in the database (S700).

Hereinafter, each step of the method for managing copyright of content according to the present invention will be described in detail.

In the step S100 of receiving the first content, the server 100 receives the first content from the user terminal 200. The first content may be transmitted to the server 100 through a network.

Here, the first content may have various formats. For example, the first content may be a work such as video, music, image, or text. Hereinafter, for convenience of description, the first content is described as an example of music.

The communication unit 110 of the server 100 is connected to the user terminal 200 through a network. The server 100 may first receive a request for uploading the first content from the user terminal 200. When the server 100 receives an upload request, the server 100 may provide an interface for uploading a file including the first content to the user terminal 200. The user terminal 200 transmits the first content data stored in the user terminal 200 or a link for accessing the first content to the server 100 by using the provided interface.

In the step of extracting the unique information of the first content (S200), the server 100 extracts the unique information of the first content.

Here, the unique information refers to information obtained by extracting only unique features that can distinguish the first content from other content. This unique information is smaller in volume and size than the first content itself, so that it is possible to determine whether the content is identical by comparing and analyzing only the teaching information without the need to compare and analyze the entire content of the first content.

The unique information may be, for example, multimedia fingerprint information. The multimedia fingerprint information may be described in various forms according to the type of content. For example, when the content is audio content, the multimedia fingerprint information may be audio fingerprint information. The audio fingerprint information is metadata extracted from a specific area of audio content. The audio fingerprint information may be used to track information of the copyright holder, seller, or purchaser even in the process of distribution after the audio content is generated by inserting the information of the copyright holder, the seller, or the purchaser in some cases.

Using such fingerprint information, it is possible to easily determine whether the contents are identical or similar.

The unique information may be other types of metadata that are distinguished from the fingerprint, such as a watermark, for example.

Referring to FIG. 3, the step (S200) of extracting the unique information of the first content may include a specific detailed step. The step of extracting the unique information of the first content (S200) includes extracting the audio signal from the first content (S210), the step of removing the audio noise of the first content (S220), the target of extracting the unique information of the audio signal It may include setting a section (S230) and generating audio fingerprint information of the audio signal (S240).

The step of extracting an audio signal from the first content (S210) may be applied when the first content is not audio content but video content. When the video content is received as the first content, the server 100 may generate audio fingerprint information by extracting an audio signal from the video. However, this step (S210) may be omitted when the first content is audio content.

In the step S220 of removing audio noise of the first content, various types of noise included in the first content are removed to generate fingerprint information for only the original signal. To this end, various types of noise removal techniques can be applied.

Specifically, in the present invention, a method in which the server 100 checks audio noise characteristic information of the first content and removes noise using an audio noise removal algorithm suitable for the characteristic information may be used.

The detailed contents of this step (S220) will be described with reference to FIG. 4. The step of removing audio noise of the first content (S220) includes checking the audio noise characteristic information of the first content (S221), selecting an audio noise removal algorithm suitable for the type (S222), and the selected audio removal algorithm It may include removing audio noise of the first content by using (S223).

Here, the step of confirming the audio noise characteristic information of the first content (S221) is a step in which the server 100 identifies the type and characteristic of the first content and checks the audio noise characteristic information according to the type and characteristic of the content. .

For example, when the first content has a characteristic of a concert recording content, the first content may include tangible noise (such as cheers of the audience). In addition, when the first content has a characteristic of a personal broadcast with specific music as background music and narration is included, the narration may be recognized as tangible noise in the first content.

A more detailed step may be performed to check the audio noise characteristic information of the first content. Specifically, the step of confirming the audio noise characteristic information of the first content (S221) includes a step (S221a) of providing a plurality of types of the audio noise characteristic to the user terminal by the server and at least one type selected by the user. It may include a step (S221b).

In the step S221a of providing the server with a plurality of types of audio noise characteristics to the user terminal, when the server 100 receives the first content upload request from the user terminal 200, the server 100 sends the user terminal 200 ) Can be implemented in the form of providing an interface. The step S221a may be displayed as an interface for selecting the type of first content to be uploaded or uploaded to the user terminal 200. Specifically, a view of a sound source officially released to the user terminal 200, an edited sound source, a sound source recorded in a concert, and a content in which the sound source is used as background music may be provided, and a request may be made to select one of these views.

The step of receiving at least one type selected by the user (S221b) may be accomplished by the user selecting one of these views and transmitting the information to the server 100.

In the step of selecting an audio noise removal algorithm suitable for a type (S222), the server 100 selects an audio noise removal algorithm suitable for the type according to noise characteristic information among a plurality of audio noise removal algorithms. Here, the type of the audio noise characteristic received in the previous step (S221b) may be utilized. To this end, the server 100 may store a plurality of audio noise removal algorithms or may be prepared in a state that can receive and use them from the outside.

The step of removing audio noise of the first content using the selected audio removal algorithm (S223) is a step in which the server 100 removes the audio noise of the first content using the audio removal algorithm selected in the previous step (S222). .

As described above, the server 100 may remove audio noise from the first content.

Referring back to FIG. 3, when the step S220 of removing audio noise from the first content as described above is completed, a step S240 of generating audio fingerprint information may be performed.

Before the server generates audio fingerprint information (S240), an operation (S230) of setting an audio fingerprint extraction target section of the audio signal may be performed. This may be to set a time period to which the audio signal is to be extracted. Setting the time interval may be performed according to a rule predetermined in the server 100.

When an audio fingerprint extraction target section of the audio signal is set, a fingerprint information generation step (S240) may be performed on the corresponding section. Through this process, audio fingerprint information of the first content may be finally generated.

Referring again to FIG. 2, the following steps will be described. When the audio fingerprint information of the first content is secured, the step of searching for the second content (S300) is performed.

In the step of searching for the second content (S300), the server 100 searches for second content that at least partially matches or is similar to the first content by using the unique information of the first content.

In the step of searching for the second content (S300), the unique information of the content stored in the unique information database 160 held by the server 100 or the unique information database 160 accessible to the server 100 and the first And comparing the unique information of the content.

The server 100 performs an algorithm for comparing the unique information of the candidate group, which may be the second content, with the unique information of the first content. This algorithm can determine whether or not two unique pieces of information are identical and how similar they are according to a predetermined criterion. The server 100 may determine second content that is at least partially coincident with or similar to the first content by using the degree of matching and the degree of similarity determined by the algorithm.

If the second content is searched in this step (S300), the process proceeds to step (S400) of determining whether the next first content is a secondary work of the second content. However, if the second content is not searched in this step (S300), the step of determining whether the first content is a secondary work of the second content (S400) does not proceed, and the unique information of the first content is stored in the unique information database. The step (S700) may be performed. The step of storing the unique information of the first content in the unique information database (S700) will be described again below.

The step S400 of determining whether the first content is a secondary work of the second content is performed when the second content is found in the previous step S300 as described above. In the step of determining whether the first content is a secondary work of the second content (S400), the server 100 directly compares the first content and the second content, or compares the unique information of the first content and the unique information of the second content. It is judged by comparison.

Here, comparing the unique information of the first content and the unique information of the second content may be the same as or different from the algorithm used in the step S300 of searching for the second content described above. Specifically, determining whether the work is a secondary work may be determined by the server 100 in consideration of at least one of the length and weight of a section that matches the unique information of the second content among the unique information of the first content.

Here, that the first content is a secondary work of the second content means that the first content is generated by using or including at least a part of the second content. Therefore, in determining whether the work is a secondary work, it can be determined by considering the initial creation time of the first content and the second content.

The step (S500) of providing copyright usage and profit information of the second content is performed when the second content is found in the previous step (S300) as described above. In addition, the step of providing copyright usage and profit information of the second content (S500) may be performed when it is determined that the first content is a secondary work of the second content.

In the step (S500) of providing copyright use and profit information of the second content, the server 100 reads information on the use and profit of the second content and provides the information to the user terminal 200.

To this end, the server 100 may include a copyright information database 150. The copyright information database 150 may be included in the server 100 including the communication unit 110 or may be included in a separate server accessible to the server 100 including the communication unit 110 in some cases.

The copyright information database 150 stores copyright usage and profit information of the second content. Here, the copyright use information may be information on whether or not a secondary work of the corresponding content is allowed to use the corresponding content as a primary work, if so, a specific permission condition, permission type, permission period, and permission area. In addition, the copyright revenue information may be information about a condition (minimum or maximum content usage fee), a distribution ratio, and a settlement method, etc. of revenue generated when a secondary work of the corresponding content uses the corresponding content as a primary work. Specifically, it may be information on how to divide the revenue generated by the secondary content into a primary content contribution and a secondary content contribution.

After the step (S500) of providing copyright usage and revenue information of the second content is performed, the user transmits information on whether or not the user agrees to the received usage and revenue information to the server 100. If the user agrees to the provided usage and revenue information, the first content service is started in the server 100.

The step of dividing the first content revenue into the first and second content contributions (S600) is performed when the service provision of the first content is started as described above, and profits are generated accordingly.

If the service of the first content is started, but no separate revenue is generated due to the separate first content, and a fee for using the second content is to be charged, the server 100 is the creator of the first content. Alternatively, you can charge a fee to the beneficiary of the service.

In the step of dividing the first content revenue into the first and second content contributions (S600), the server 100 divides the revenue generated based on the first content into a first content contribution and a second content contribution.

The server 100 may distribute the divided profits to creators or service beneficiaries of the first content and the second content after classifying the profits.

In the step of storing the unique information of the first content in the database (S700), the server 100 stores the unique information of the first content in the unique information database 160. The unique information of the first content stored in this way may be used to determine whether the first content is used as a primary work of another third content.

In the step of storing the unique information of the first content in the database (S700), it is possible to store not only the unique information of the first content but also information on the copyright use and profit of the first content. Information on the copyright usage and profit of the first content may be stored in the copyright information database. In addition, the unique information of the first content and information on the copyright use and profit of the first content may be matched and stored.

In some cases, the first content may be both a secondary work and a primary work. That is, the first content may be a secondary work using the second content and a primary work for the third content. In this case, when the server 100 receives the third content and extracts the unique information of the third content, the second content may be explored as a primary work. In addition, in this case, the revenue generated by the third content may be divided into a first content contribution, a second content contribution, and a third content contribution.

The step of storing the unique information of the first content in the database (S700) may be performed at any point after the step of extracting the unique information of the first content (S200). For example, storing the unique information of the first content in the database (S700) is after the step (S400) of determining whether the first content is a secondary work of the second content, and the copyright usage and profit information of the second content It is also possible to be performed before the providing step (S500).

In the above, embodiments of the copyright management method of the present invention have been described. The present invention is not limited to the above-described embodiments and the accompanying drawings, and various modifications and variations are possible from the perspective of those of ordinary skill in the field to which the present invention pertains. Therefore, the scope of the present invention should be defined by the claims of the present specification as well as those equivalents to the claims.
