The technical field

The present invention relates to digital rights management (hereinafter called "DRM"). More specifically, the invention relates to a method for granting a license to the client device corresponding to the encrypted content, which provides a license in response to the license request, relevant content that is distributed through superdistribution to a third party in the system convert DRM and convert DRM it uses.

Prior art

With the development and popularization of computer engineering was digitized most commercial of copyrighted works, such as books, magazines, comics, soundtracks, movies, radio or newspaper, produced, operated and governed in analog form.

Despite the fact that the commercial objects of copyright are reusable, they are always high quality and they are easy to copy and modify. Moreover, it is easy to transfer and distribute, even large objects of copyright in a short time. Such characteristics and advantages of digital forms are the cause of digitizing analog copyright gaining momentum.

However, such advantages of digital forms may apply to the to the driving force behind the violation of the rights of authors and benefits of copyright. Because the copy is identical to the original, it weakens the desire to buy the original, and correct, and copy without the author's approval are simple, the object of copyright is easy to steal, transmit, and distribute. Accordingly, illegal copyright instantly distributed over the Internet, it is impossible to legally manage.

These negative factors can reduce the mood of the author, which can reduce the desire to create, in respect of copyright. In addition, they can cause to the authors doubted the transition to digital form. Accordingly, there is a need for technical protection device for digital copyright objects, which allows for effective management of copyright, while maintaining the benefits of the digital form.

Accordingly, in order to protect the rights and benefits of digital copyright, the proposed technology application of DRM for digital content. In addition, it uses various types of DRM.

DRM is a method that prevents the use of digital content without permission, in order to protect copyright and advantages of the copyright owner. Usually provide content server using the DRM encrypts and transmits the content and the PE edit license valid users, so that only valid users can reproduce and display the content. The license includes a content encryption key used to decrypt the content, and the right to use the content, which is the information content.

On the other hand, in the prior art, the client device reproduces and displays only the contents through a predetermined type of DRM. Moreover, in the same way, the server delivers the content to the client device by applying to it some type of DRM.

Fig. 1 is an image showing a variant of the method for providing a client device to the content to which DRM is applied, according to the prior art.

The client device 110 is connected to the first server 120 corresponding to the first type of DRM, through a predetermined communication network. The first server 120 includes a server of the content delivery server edition license. When the client device 110 sends a request to content server 120 of the content delivery server 120 providing transmits content to the client device 110 content encrypted under the first type of DRM. The client device 110 sends a license request to the server 120 edition license is, corresponding to the first type of DRM to observe the copyright of the encrypted content. After the client device 110 receives issued a license from the server 120 to issue licenses, it can use the content. That is, the client device 110 decrypts, reproduces and outputs the encrypted content using the decryption key included in the license.

Since the first server 120 in accordance with the prior art provides only content encrypted by a predetermined type of DRM, it cannot provide the content encrypted by other types of DRM.

Moreover, in Fig. 1, along with the fact that the user plays back the content using the client device 110, when the user reproduces the same content using the second client device 130 that supports the second type of DRM, it can transfer content from a client device 110 to the second client device 130. However, because the second client device 130 supports the type of DRM that is different from the type of the client device 110, may be reproduced content transmitted to the second client device 130 from the client device 110.

In order to solve such problems, Korean patent publication No. 10-2005-0120579 described the scheme of the La support input and output of content between devices of different types of DRM. Patent publication pre-emptive in that it can be used between devices of different types of DRM by type conversion DRM from content. However, when the content that is converted to the type of DRM, extends through superdistribution a third party because the third party does not possess a license corresponding to the content, the third party may not be reproduced distributed through superdistribution content.

Accordingly, there is a need for a method that allows obtaining a license by a third party, when the content that is converted to the type of DRM, extends through superdistribution third party. The server corresponding to the DRM before converting, you may participate in providing an appropriate license to the user to freely distribute the content via superdistribution. At the same time, there is a need in the DRM conversion system that allows the license management content distributed through superdistribution.

The best option for carrying out the invention

In the present invention, the first server is a server corresponding to the first DRM and the second server is a server corresponding to the second DRM.

Further, with reference to the accompanying drawings will be explained a method of providing a client device license corresponding to encrypted content, and using that DRM conversion system according to the preferred options for implementation of the present invention.

Fig. 2 - the image schematically showing the description of the network connection system of converting DRM, according to a variant implementation of the present invention.

It is assumed that the first client device 202 on the supports of the first type of DRM, and the second client device 205 and the third client device 206 support the second type of DRM.

As shown in Fig. 2, the first client device 202 receives the first content of the first type of DRM and the first license corresponding to the first content, and reproduces the first content. Here the first server 201 may be a server for providing the content and the license of the first type of DRM.

When the user of the client device 202 wishes to reproduce the first content from the second client device 205, the system 203 conversion converts DRM DRM first content of the first type of DRM and the first license corresponding to the first content to form a second content of the second type of DRM, and a second license corresponding to the second content. In the embodiment of the present invention, the first client device 202 and the second client device 205 support respectively different types of DRM. For example, the first type of DRM can be MS-DRM, and the second type of DRM can be OMA-DRM-protected content.

Convert DRM converts the first content of the first type of DRM and the first license in the intermediate format, and then converts the intermediate format into a second content of the second type of DRM and a second license. Convert DRM is described in detail in Korean patent publication No. 2005-120579.

On the other hand, when the second client device 205 distributes the converted content by superdistribution third client device 206, a third party, the third client device 206 to use the content passes the request to the license corresponding to the second content, the system 203 convert DRM. System 203 convert DRM receives the license request and shall receive from the second server 204 and transmits the third client device 206 a second license corresponding to the second content distributed through superdistribution third client device 206. In the embodiment of the present invention, the second client device 205 and the third client device 206 support the same type of DRM.

Here superdistribution aimed at the dissemination of content and licenses separately. The user can distribute them used the contents to a third party through superdistribution. The third person, taking the content that receives the license, regardless of the contents and uses common content.

Here the third client device 206, requesting a license, may request approval from the first server 201 together with the license request. When the system 203 convert DRM receives a license request from a third client device 206, it may request from the first server 201 approve the issuance of a license to the relevant content.

When the system 203 pre is obrazovaniya DRM receives a license request from a third client device 206 and requests approval of the issuance of a license to the relevant content from the first server 201, server convert DRM can identify the first server 201 corresponding to the type of DRM to content conversion, which requests a license by accessing the database Protocol conversion.

That is, the system 203 convert DRM writes to the database Protocol conversion Protocol conversion DRM, convert DRM. When the system 203 convert DRM receives a license request for particular content, it can identify the DRM server, the corresponding DRM to convert the associated content, by accessing a database of Protocol conversion.

System 203 convert DRM may be composed of a server convert DRM and customer conversion DRM. That is a separate system circuit 203 convert DRM can be included in a server, convert DRM, and the remaining diagrams can be included in the client convert DRM-protected content.

In the embodiment, the system 203 convert DRM may include only the translation server without DRM client convert DRM. In this case, the server convert DRM performs all functions 203 convert DRM-protected content.

Each of the client devices 202, 205 and 206, in accordance with the present invention, may include a personal computer, personal digital assistants (PDA), smart phone, pocket PC, re Osney phone, MP3 player, the predetermined communication module such as module multiple access, code-division multiplexing, a Bluetooth module, a communication module in the IR range, charge wired/wireless local area network, and can carry a given microprocessor to perform the function of the media to perform a set of computational steps.

Fig. 3 is a block diagram of the algorithm, showing how the DRM conversion system according to a variant implementation of the present invention.

At step 301, the DRM conversion system converts the first content of the first type of DRM and the first license corresponding to the first content to form a second content of the second type of DRM and a second license corresponding to the second content. For example, the DRM conversion system can convert the first "wish list" the contents of the first type of DRM and the first license corresponding to the first "desired" content to form a second desired content of the second type of DRM and a second license corresponding to the second "desired" content.

In the embodiment of the present invention, the DRM conversion system can record the conversion of DRM in the database. For example, the Protocol conversion, the DRM may include first content information converting DRM on the basis of the transformation the first DRM license corresponding to the first content or the information server to issue a license relative to the first content.

In addition, in another embodiment of the present invention part of the DRM conversion system can be installed on the terminal client.

At step 302, the DRM conversion system receives the request for the license corresponding to the second content distributed to a third party through superdistribution. That is, in the present invention, since the third person takes only a second content from a client device, providing the second content, the third party queries the system convert DRM license corresponding to the second content.

In this case, when you stop a server corresponding to the type of DRM to convert, and issued a second license corresponding to the second distributed content, this leads to an inappropriate rejection of the source of the content.

At step 303, the DRM conversion system is requesting approval or disapproval in accordance with the license request to the first server. That is, since a license is obtained by converting the first license corresponding to the first content of the first type of DRM, and the first license is issued from the first server, the DRM conversion system makes a request for the approval the Oia or disapproval in accordance with the license request. Moreover, the DRM conversion system may identify the first server by accessing the database, which records the Protocol converting DRM-protected content.

In the embodiment, the DRM conversion system does not request approval or disapproval in accordance with the license request, but the third party may request approval from the first server with the license request. At the same time, the DRM conversion system may provide third party information to the first server corresponding to the type of DRM to convert.

When the answer of approval is received from the first server (step 304), the DRM conversion system requests the second server, the second license corresponding to the second content distributed through superdistribution third party (step 305).

At step 306, the DRM conversion system receives from the second server a second license corresponding to the second content distributed through superdistribution, and transmits a second license to a third party.

In the embodiment of the present invention, when the DRM conversion system receives a reply of approval from the first server, it can take from the first server distribution prescribed value of money charged by a third party. In addition, the DRM conversion system can provide cha is th value distributed money to the second server.

Fig. 4 is a block diagram of the algorithm, showing the method of operation of a client device, according to a variant implementation of the present invention.

At step 401, the client device receives the content from the source device through a predetermined conversion DRM. Here the content is the content that is converted from a first type of DRM to the second type of DRM. For example, the source device via the DRM conversion system distributes through superdistribution desired music content converted to the type "2 DRM from DRM 1, a client device a third party. Accordingly, the client device can receive the desired music content converted to the type "DRM 2".

At step 402, the client device queries the system convert DRM license corresponding to the content converted to the second type of DRM.

In the embodiment of the present invention, the client device may send the first server request approval corresponding to the license request. In addition, the DRM conversion system may transmit to the first server a request for approval of issue of the license corresponding to the license request.

At step 403, the DRM conversion system receives the request for the license corresponding to the content converted by the second the imps DRM.

At step 404, when the DRM conversion system receives a reply of approval from the first server corresponding to the first type of DRM, it transmits to the second server, a license request for the content.

At step 405, the DRM conversion system takes the license for the content from the second server.

At step 406, the DRM conversion system transmits the accepted license to the client device.

At step 407, the client device receives the license corresponding to the converted content from the second server through the DRM conversion system.

In the embodiment of the present invention, the client device may be able to pay at least one server associated with the first type of DRM, the DRM conversion system, and a server corresponding to the second type, a predetermined amount of money for the license corresponding to the converted content. Here any of the server associated with the first type of DRM, the DRM conversion system, and a server corresponding to the second type, receives payment of the prescribed value of money, and the server (or system), taking payment, you may allocate a predetermined amount of money to other servers (systems).

According to a variant implementation of the present invention, the license corresponding to the converted content is produced behold verum, corresponding to the second type of DRM, and may include one decryption key for the content of the second type of DRM or information usage rights for the content.

Fig. 5 is a block diagram of the internal arrangement convert DRM according to a variant implementation of the present invention.

As shown in Fig. 5, the system 500 convert DRM includes Converter 501 DRM, base 502 data Protocol conversion, the receiver 503 license request, section 504 request approval and section 505 of the grant of the licence. In the embodiment of the present invention the part of the system 500 convert DRM can be installed on the terminal client.

The Converter 501 converts DRM first content of the first type of DRM and the first license corresponding to the first content to form a second content of the second type of DRM and a second license corresponding to the second content.

In the embodiment of the present invention, the Converter 501 DRM can record the conversion of DRM in accordance with the conversion of DRM in the database 502 data Protocol conversion.

The receiver 503 license request accepts the request of the license corresponding to the second content that is distributed through superdistribution third party.

In the embodiment of the present invention behold the tion 504 request approval requests the first server, corresponding to the type of DRM before conversion, approval or disapproval in accordance with the license request. In addition, section 504 of the request for approval may identify the first server by accessing the database Protocol conversion, in which is written the Protocol converting DRM-protected content.

When section 505 of the grant of the licence receives approval, it queries the second server a second license corresponding to the second content distributed through superdistribution third party, and receives and transmits a second license corresponding to the second content distributed through superdistribution third party.
