The present invention relates to a user-generated content service using digital rights management, and more particularly, to a user-generated content service method for allowing a user-generated content service to be performed only on one website using digital rights management.

Recently, with the evolution of the Internet and the development of digital authoring tools, the production and distribution of User Created Contents (UCC) is rapidly spreading, and the copyright issue related to user generated contents is emerging as a new issue.

However, as a way to solve the copyright problem, if the user wants to protect the rights of the contents author by simply applying a digital rights management system (hereinafter referred to as 'DRM') to user-generated content, activation of user-generated content is required. It can be shrunk.

Accordingly, there is a need for a method for facilitating the dissemination of user-generated content generated by others and activating the dissemination of user-generated content and at the same time protecting the rights of authors for the user-generated content.

It is an object of the present invention to provide a user-generated content service freely from a single website using DRM.

The object of the present invention is not limited to the above-mentioned object, and other objects that are not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, the user-created content service method according to an embodiment of the present invention (D) encrypting the uploaded content from the client accessing the website by applying the DRM, and storing the encrypted content (b) downloading the stored encrypted content; and (d) registering the downloaded content with the DRM applied to the edited content. do.

In order to achieve the above object, the user-created content service method according to an embodiment of the present invention comprises the steps of (a) downloading the DRM applied content from a website, (b) releasing the DRM from the content, (C) editing the content of which the DRM has been released, and uploading to the website by applying the DRM to the edited content.

Specific details of other embodiments are included in the detailed description and the drawings.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, and only the embodiments make the disclosure of the present invention complete, and the general knowledge in the art to which the present invention belongs. It is provided to fully inform the person having the scope of the invention, which is defined only by the scope of the claims.

1 is a diagram illustrating a system for a user generated content service according to an embodiment of the present invention.

Referring to FIG. 1, the system 100 according to the present invention includes web servers 110 and 130 for storing user-produced content in various forms such as moving images and still images or providing user-produced content that is already stored. Clients 150 and 180 for downloading and executing or editing user-generated content stored in the web servers 110 and 130 and the web servers 110 and 130 and the clients 150 and 180 may be connected to a wired or wireless medium. It includes a network 190 to connect through. In addition, the system 100 according to the present invention may further include a DRM server 195.

The network 190 may include any type of communication network capable of transmitting data information, including a general mobile communication network or an internet communication network.

The DRM server 195 may be connected to the web servers 110 and 130 or the clients 150 and 180 through the network 190, and the web servers 110 and 130 or the clients 150 and 180 may be connected. Provides DRM information about user-generated content uploaded or downloaded at the request of.

In this case, the clients 150 and 180 may provide a function of uploading user-generated content produced by the users 140 and 160 to the web servers 110 and 130. 130 stores the uploaded content by applying DRM.

DRM is a technology concept for protecting digital content that is easy to copy and distribute. It is a right object to allow access to digital content only to users who pay a certain price or to use encrypted digital content. It is a technology that prevents illegal distribution of digital content by requiring a license called RO). Conventional technologies related to such DRM include OMA DRM (Open Mobile Alliance DRM) technology and US DRM system.

For example, when the user-generated content to which the DRM is applied is stored in the web server A 110, the user A 140 may download and edit or execute the stored user-generated content from the web server A 110. In this case, since the downloaded user-created content has been applied with DRM, the client A 150 should also be equipped with the same DRM system as the DRM system mounted on the web server A 110.

In addition, the user A 140 completes the editing of the downloaded user-created content, and uploads the edited user-created content to a web server B 130 other than the web server A 110 that was originally stored. In this case, uploading is not normally performed. Since the DRM is applied when the edited user-created content is uploaded, even if the DRM system is not mounted or mounted on the web server B 130, a DRM system different from the DRM system mounted on the web server A 110 is mounted. In this case, the uploading itself to the web server B 130 may not be performed or may be difficult to be normally serviced even when uploaded.

Instead, user A 140 may upload the edited user-generated content to web server A 110, and the edited user-generated content may be stored in web server A 110 along with the original user-generated content. .

In this manner, user-generated content registered on any web server, i.e., any web site, can be edited or executed by multiple clients equipped with the same type of DRM system mounted on the web server. The user-produced content or executed user-produced content may not be posted to other websites, thereby enabling the utilization of the user-produced content under certain requirements and at the same time preventing illegal distribution of the user-produced content.

2 is a block diagram showing the configuration of a web server according to an embodiment of the present invention, and corresponds to the web server A 110 or the web server B 130 shown in FIG. 1.

2, the web server according to the present invention includes a client interface module 210, a decoding module 220, an encoding module 230, a DRM interface module 240, a DRM packaging module 250, and a storage module ( 260 and downloading processing module 270.

The client interface module 210 receives uploaded user-generated content or downloads user-generated content while communicating with a plurality of clients 150 and 180 via the network 190.

The decoding module 220 decodes the uploaded user generated content, and the encoding module 230 re-encodes the decoded user generated content.

The DRM interface module 240 is connected to the DRM server 195 to receive DRM information from the DRM server 195 such as an authentication key, an encryption key, a rights object, etc. required for the web server to apply DRM to user-generated content. In this case, applying DRM may be understood as encrypting content using the above DRM information.

The DRM packaging module 250 encrypts user generated content encoded by the encoding module 130 using the DRM information.

The storage module 260 stores user generated content encrypted by the DRM packaging module 250.

If there is a request for downloading from the client, the downloading processing module 270 extracts the user-generated content stored by the storage module 260, adds the DRM information and the attribute information on the user-generated content, and then downloads the downloaded content. For the transfer to the client interface module 210.

In this case, the DRM information added by the downloading processing module 270 may include website information operated by a web server, client information for downloading, user information for downloading, and the like. In addition, the attribute information indicates information indicating whether the user-produced content is executable or editable.

In addition, the downloading processing module 270 may release and download the DRM when the uploading user and the downloading user are the same.

3 is a block diagram showing the configuration of a client according to an embodiment of the present invention, and corresponds to Client A 150 or Client B 180 shown in FIG.

Referring to FIG. 3, the client according to the present invention includes a server interface module 310, a control module 320, an editing module 330, a content execution module 340, and a user-generated content generation module 350.

The server interface module 310 receives the downloaded user-generated content or uploads the user-generated content while communicating with the web server through the network 190.

The editing module 330 provides a means for editing the downloaded user-generated content, and the content execution module 340 provides a means for executing the downloaded user-generated content.

The user-generated content generation module 350 generates user-generated content using a web camera connected to a client or an application program for capturing data. In addition, the user-generated content generation module 350 may extract and provide content stored in the connected storage medium by accessing another storage medium connected to the client.

The control module 320 controls operations between the server interface module 310, the editing module 330, the content execution module 340, and the user-generated content generation module 350.

The editing module 330 and the content execution module 340 may have the same DRM function as that of the DRM mounted on the web server. The DRM software may be downloaded and installed from the DRM server 195 or a web server. An editing module or a content execution module with a DRM function may be downloaded from a web server.

The client may receive DRM information such as an authentication key, encryption key, rights object, etc. necessary for applying DRM to user-generated content from the web server, but may also receive it from the DRM server 195, and for this purpose, the DRM server 195 It may further comprise an interface means for communication with.

Hereinafter, a method of providing a user-generated content service according to the present invention by the operation of each component illustrated in FIGS. 2 and 3 will be described in detail.

In this case, the "user-generated content service" in the present specification includes uploading the user-generated content to the web server or downloading the user-generated content stored in the web server by the client. In addition, the 'user-generated content service' includes a client downloading and executing or editing user-generated content stored in a web server.

4 is a flowchart illustrating a process of uploading user-generated content according to an embodiment of the present invention, which may be understood as a process of registering user-generated content for the first time.

First, user-generated content is generated by the user-generated content generation module 350 of the client (S410). In this case, the generated user-created content may be edited by the editing module 330.

The control module 320 accesses a website provided by the web server and uploads the generated user-generated content through the server interface module 310 (S420). In this case, the control module 320 generates the uploaded file for efficient uploading. The user-produced content may be encoded and uploaded, and information identifying a client or information of a user uploading the content may also be uploaded.

When the client interface module 210 of the web server receives the uploaded user-generated content from the client and transmits the generated user-generated content to the decoding module 220, the decoding module 220 decodes the delivered user-generated content and then operates the web server. The encoding module 230 re-encodes the decoded user generated content to be suitable (S430).

Then, the DRM packaging module 250 applies the DRM to the encoded user-generated content to package it (S440). In this case, the DRM information required for applying the DRM may be received or stored in advance when the user-created content is uploaded, or may be provided through the DRM interface module 240. Examples of the DRM information may include an authentication key, encryption key, rights object, user information, client information, and the like.

The storage module stores the DRM packaged user-generated content by the DRM packaging module 250, thereby completing the uploading process of the user-generated content (S450).

5 is a flowchart illustrating a process of downloading user-generated content according to an embodiment of the present invention.

When the user downloads the user-generated content stored in the web server, the downloading processing module 270 extracts the corresponding DRM content from the DRM content stored by the storage module 260 (S510). In this case, the DRM content refers to user-generated content packaged by the DRM packaging module 250.

The downloading processing module 270 determines whether the user who has requested the downloading is the same as the user who uploaded the extracted DRM content, that is, the content publisher (S520). This determination may be performed based on user information (eg, user identification information or password) used when the user accesses the web server through the client.

If the content publisher and the downloading user are the same, the DRM applied to the user-generated content is released (S530). Otherwise, the DRM information is added (S540). The added DRM information may include client information and website information of a web server.

Then, the downloading processing module 270 adds attribute information indicating information indicating whether the user-produced content is executable or editable (S550), and then sends the requested user-generated content to the client interface module 210. Download to the client through (S560).

The user-generated content downloaded according to the attribute information is not allowed to be edited but can be executed only, or both editing and execution can be allowed, and the content of the attribute information is uploaded when the corresponding user-generated content is uploaded. Can be determined by the user.

On the other hand, when the content publisher and the downloading user are the same, the downloading processing module 270 may release the DRM applied to the user-generated content and download the same to the client without adding additional attribute information.

6 is a flowchart illustrating a process of executing user-generated content according to an embodiment of the present invention.

First, according to the method illustrated in FIG. 5, the server interface module 310 of the client accesses a website provided by a web server and downloads user-generated content to which DRM is applied (S610).

Then, the control module 320 determines whether a player with a DRM function exists in the client, that is, whether the content execution module 340 provides the DRM function (S620).

If the content execution module 340 mounted on the client merely provides a function of executing user-generated content, the control module 320 checks whether separate DRM software is mounted on the client (S630). In this case, the DRM software corresponds to the DRM system mounted on the web server, and may be provided by the web server and installed in the client.

If even the DRM software is not mounted on the client, the control module 320 displays a message indicating that execution of the downloaded user-generated content is not possible through the screen of the client (S640).

On the other hand, if the content execution module 340 provides the DRM function or if the separate DRM software is installed on the client, the content execution module 340 or the DRM software checks the DRM information and the user who wants to execute the content is justified. Check whether the user (S650).

If it is confirmed that the user who wants to execute the content is a legitimate user, the content execution module 340 determines whether the downloaded content is executable (S660).

Whether the content can be executed or not can be determined by attribute information attached when the content is downloaded. For example, if the attribute information is set to not executable, it is not executed even if it is recognized as a legitimate user. In this case, whether or not it may be executed may be determined according to the conditional attribute information. For example, it may be executed only when a corresponding condition is satisfied according to user information (age, gender) or client information (IP address).

If it is recognized that the user is a legitimate user by confirming the DRM information, the DRM of the downloaded user-generated content is released to decrypt the encrypted user-generated content.

After the operation S660 is performed, if it is determined that execution of the downloaded content is not possible, the control module 320 or the content execution module 340 displays a message indicating that the execution of the downloaded user-generated content is impossible. Display through the screen (S640).

On the other hand, if it is determined that execution of the downloaded user-generated content is possible, the content execution module 670 decodes and executes the user-generated content (S670).

7 is a flowchart illustrating a process of editing user-generated content according to an embodiment of the present invention.

First, according to the method illustrated in FIG. 5, the server interface module 310 of the client accesses a website provided by a web server and downloads user-generated content to which DRM is applied (S710).

Then, the control module 320 determines whether there is a letter equipped with a DRM function on the client, that is, whether the editing module 330 provides the DRM function (S720).

If the editing module 330 mounted on the client provides only a function of simply editing user-generated content, the control module 320 checks whether separate DRM software is mounted on the client (S730). In this case, the DRM software corresponds to the DRM system mounted on the web server, and may be provided by the web server and installed in the client.

If even the DRM software is not mounted on the client, the control module 320 displays a message indicating that editing of the downloaded user-generated content is impossible through the screen of the client (S740).

Meanwhile, when the editing module 330 provides the DRM function, the editing module 330 checks the DRM information to check whether the user who wants to edit the content is a legitimate user (S750). The DRM information that can be used at this time may include website information, user information, and the like.

If it is confirmed that the user who wants to edit the content is a legitimate user, the editing module 330 determines whether editing of the downloaded content is possible (S760).

Whether the content can be edited can be determined by attribute information attached when the content is downloaded. For example, when the attribute information is set to not editable, editing is not performed by the editing module 330 even if it is recognized that the user is a legitimate user. At this time, whether or not editing is possible may be determined according to the conditional attribute information. For example, it may be edited only when a corresponding condition is satisfied according to user information (age, gender) or client information (IP address).

If it is recognized that the user is a legitimate user by confirming the DRM information, the DRM of the downloaded user-generated content is released to decrypt the encrypted user-generated content.

After the operation S760 is performed, if it is determined that editing of the downloaded content is not possible, the control module 320 or the editing module 330 may display a message indicating that editing of the downloaded user-generated content is impossible. Display through (S740).

On the other hand, if it is determined that editing of the downloaded user-generated content is possible, the user edits the downloaded user-generated content using the editing means provided by the editing module 330 (S770). After the user finishes editing, if the user saves the edited user-generated content, the editing module 330 applies the DRM to the edited user-generated content, the control module 320 is a web that downloaded the user-generated content before editing Control uploading user-generated content edited on the site. In this case, the edited user-generated content is preferably stored in the form of a file.

On the other hand, if the separate DRM software exists in the client in step S730, the DRM software controls the general-purpose editor. At this time, the general-purpose editor does not provide a DRM function by itself and performs editing under the control of the DRM software. That is, when the user attempts to edit using the general-purpose editor, the DRM software releases the DRM applied to the downloaded user-generated content (S780). Herein, releasing the DRM may be understood as decrypting the encrypted content using the DRM information. Thereafter, the DRM software causes the general-purpose editor to edit user-generated content (S782), and then applies DRM again when the editing is finished and stored (S784). At this time, the edited user's information may be added.

If you register on the original website after editing as above, other users can download or execute it, but if you register on another website, DRM is different so the above service is not provided.

If the edited user-generated content is delivered to another user rather than uploaded to the original website, the other user has a player or editor that subscribes to the original website and provides DRM functionality or downloads the aforementioned DRM software. If it is installed, it can be executed or edited by other users.

Meanwhile, the term 'module' used in the present embodiment refers to software or a hardware component such as an FPGA or an ASIC, and the module plays a role. However, modules are not meant to be limited to software or hardware. The module may be configured to be in an addressable storage medium and may be configured to play one or more processors. Thus, as an example, a module may include components such as software components, object-oriented software components, class components, and task components, and processes, functions, properties, procedures, subroutines. , Segments of program code, drivers, firmware, microcode, circuits, data, databases, data structures, tables, arrays, and variables. The functionality provided within the components and modules may be combined into a smaller number of components and modules or further separated into additional components and modules. In addition, the components and modules may be implemented to play one or more CPUs in a device or secure multimedia card.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.

According to the present invention, since user-generated content can be serviced only in one website, it is possible to prevent illegal distribution of user-generated content and to activate user-generated content service using a web server. .
