技术领域 FIELD

[0001] 本发明涉及数字版权管理(下文称作'DRM')。 [0001] The present invention relates to digital rights management (hereinafter referred to as 'DRM'). 更具体地说,本发明涉及一种用于为客户端装置提供对应于加密内容的许可证的方法,该方法可以在DRM转换系统中响应于与超分配给作为第三人的第三客户端装置的内容相对应的许可证请求而提供许可证,还涉及使用该方法的DRM转换系统。 More particularly, the present invention relates to a method for a client device for providing a license corresponding to the encrypted content, the method may be responsive to the third and Super assigned to the third party client in a DRM conversion system content device corresponding to the license request and provide the license, also relates to the use of this method to convert DRM system.

背景技术 BACKGROUND

[0002] 随着计算机技术的发展与普及,大部分以模拟形式制作、保存以及管理的商业交易版权客体,如书籍、连环漫画、唱片、电影、广播或报纸已被数字化。 [0002] With the development and popularization of computer technology, most analog form production, preservation and management of business transactions copyright objects, such as books, comics, music, movies, radio or newspapers have been digitized.

[0003] 尽管数字化的商业交易版权客体被反复使用,但它们具有持久的高质量,并且易于复制和修改。 [0003] Although the digitization of business transaction subject matter of copyright is repeatedly used, but they have a long-lasting, high-quality and easy to copy and modify. 此外,即使是大量的版权客体也易于在短时间内传送和散布。 In addition, even if a large number of objects are also easy to copyright in the transport and spread in a short time. 数字形式的这种特点和优点使得模拟版权客体被高速地数字化。 Digital form such features and advantages of the subject matter of copyright is the analog to digital high speed.

[0004] 然而,数字形式的这些优点会成为侵犯作者版权以及版权客体利益的因素。 [0004] However, these advantages in digital form factor will be the object of infringement of copyright and copyright interests. 由于拷贝与原版相同,从而使购买原版的意愿减弱,并使得不经作者同意的修改和拷贝变得很简单,因此容易偷窃、传送和散布版权客体。 Because identical copies of the original, so that the will weaken the original purchase, and to modify and copy could not be agreed by the author becomes very simple, so easy to steal, transmit and distribute copyright objects. 因此,违法的版权客体即刻在互联网上传播,结果是不能从法律上控制它们。 Therefore, the subject matter of copyright law on the Internet instantly spread, the results can not control them from the law.

[0005] 这种消极因素降低了作者的热情,并且能降低对于版权客体的制作意愿。 [0005] This negative factor in reducing the author's enthusiasm for the subject matter of copyright and can reduce the production of wishes. 而且,这些消极因素使作者对数字化产生了疑虑。 Moreover, these negative factors make the digitized author had doubts. 因此,对于数字版权客体,需要一种技术保护设备能够有效地管理版权,同时充分保证数字化带来的优点。 Therefore, for digital rights object, the need for a technical protection devices to efficiently manage copyright, taking full advantage of digital technology brings assurance.

[0006] 因此,为了保护数字版权客体的利益和权益,提出了一种将DRM应用到数字内容的技术。 [0006] Therefore, in order to protect the copyright of digital objects interests and rights, proposed a DRM technology is applied to digital content. 而且,各种DRM类型已被使用。 Furthermore, various types of DRM have been used.

[0007] DRM是一种为了保护版权持有者的利益和权益而防止未经允许使用数字内容的技术。 [0007] DRM is an order to protect the interests and rights of copyright holders to prevent unauthorized use of digital content technology. 通常,用于提供使用DRM类型的内容的服务器对内容进行加密并发送,并且传送许可证至授权的用户以使得只有授权用户才能再现并输出该内容。 Typically, the type used to provide the use of DRM content server encrypts and sends the content, and to transfer the license to authorized users so that only authorized users can reproduce and output the content. 许可证包括用于解密内容的内容解密密钥和作为内容使用信息的内容使用权限。 License includes a content decryption key and decrypting the content using the content information as a content utilization right.

[0008] 另一方面,在相关技术中,客户端装置只是再现和输出预定DRM类型的内容。 [0008] On the other hand, in the related art, the client device is reproduced and output a predetermined type of DRM content. And

且,以同样方式,服务器通过应用一种DRM类型而向客户端装置提供内容。 And, in the same manner, by applying a DRM server type to provide content to the client device.

[0009] 图1是表示根据相关技术用于将应用DRM的内容提供给客户端装置的方法的实施 [0009] FIG. 1 is a diagram for the application of DRM content to the embodiment of the method of the client apparatus according to the related art

例的视图。 Example view.

[0010] 客户端装置110通过预定的通信网络与对应于第一DRM类型的第一服务器120连接。 [0010] The client device 110 via a predetermined communication network corresponding to the first type of the first DRM server 120 is connected. 第一服务器120包括内容提供服务器和许可证颁发服务器。 The first server 120 includes a content providing server and licensing server. 当客户端装置110将内容提供请求发送至内容提供服务器120时,内容提供服务器120将经第一DRM类型加密的内容发送至客户端装置110。 When the client device 110 sends the request to the content provider the content providing server 120, the content providing server 120 transmits the first type of DRM encrypted content to the client device 110. 客户端装置110将许可证请求发送至对应于第一DRM类型的许可证颁发服务器120,从而实现上述加密内容的版权保护。 The client device 110 will permit request to correspond to the first type of DRM licensing server 120, enabling the encrypted copyrighted content. 在客户端装置110从许可证颁发服务器120收到所颁发的许可证之后,它就可以使用内容。 After the client device 110. The server 120 receives from the license issued by the licensing, it can use the content. S卩,客户端装置110使用包含在许可证中的解密钥而对加密内容进行解密、再现以及输出。 S Jie, the client device 110 using the decryption key included in the license and decrypts the encrypted content, reproduction and output.

[0011] 由于根据相关技术的第一服务器120只提供由预设的DRM类型所加密的内容,因此不能提供由其他DRM类型所加密的内容。 [0011] Since the related art according to a first server 120 provided by the type of preset DRM encrypted content, and therefore can not be provided by other types of DRM encrypted content.

[0012] 此外,在图1中,在用户使用客户端装置110再现内容的同时,当用户使用支持第二DRM类型的第二客户端装置130再现相同内容时,他能将上述内容从客户端装置110传送至第二客户端装置130。 When [0012] Further, in FIG. 1, the user uses client device 110 to reproduce the content, while when the user uses a second type of support for the second DRM client device 130 to reproduce the same content, he can from the client above transfer means 110 to the second client device 130. 然而,由于第二客户端装置130支持的DRM类型不同于客户端装置IIO支持的DRM类型,因此不能再现从客户端装置IIO传送到第二客户端装置130的内容。 However, since the second client device 130 supports the DRM client device type is different from IIO supports DRM type and can not be reproduced from the client device IIO content to the second client device 130.

[0013] 为了解决这种问题,韩国专利公开文献No. 10-2005-0120579已介绍了一种支持不同DRM类型的设备之间进行内容的输入和输出的配置。 [0013] In order to solve this problem, Korean Patent Publication No. 10-2005-0120579 has introduced a support DRM content between different types of input and output device configuration. 上述专利公开文献的优势在于它能通过转换内容的DRM类型而在不同DRM类型的设备之间使用。 Disclosed in the aforementioned Patent Document advantage that it can convert the content through DRM DRM type and between different types of equipment used. 然而,当将转换了DRM类型的内容超分配给作为第三人的第三客户端装置时,由于作为第三人的第三客户端装置没有用于相应内容的许可证,因此作为第三人的第三客户端装置不能再现所超分配的内容。 However, when the conversion of the DRM content type is assigned to a third party over a third client device, as a third party due to a third client device corresponding content license is not used, so as a third person The third client device can not reproduce the super distribution content. [0014] 因此,需要一种方法可以实现当将转换了DRM类型的内容被超分配给作为第三人 [0014] Thus, a method can be realized when the conversion of the DRM content type is assigned to a third party over

的第三客户端装置时,可使该作为第三人的第三客户端装置能获得许可证。 When the third client device allowing the third person, as a third client device can obtain a license. 对应于转换之前的DRM的服务器端可参与向用户提供相应的许可证以自由地超分配内容。 Corresponding to the conversion before the DRM server can participate to provide users with the appropriate license to freely allocate over content. 同时,要求DRM At the same time, the requirements of DRM

转换系统能控制被超分配的内容的许可证。 Conversion system is able to control the distribution of content over a license. 发明内容 SUMMARY

[0015] 因此,为解决在现有技术中出现的上述问题而提出本发明,并且本发明的一个目的是提供一种用于向客户端装置提供对应于加密内容的许可证的方法以及使用该方法的DRM转换系统,即当由DRM转换系统进行DRM转换的内容被超分配给作为第三人的第三客户端装置并收到来自所述作为第三人的第三客户端装置的许可证请求时,就会响应于所述许可证请求接收来自对应于被加密DRM类型的服务器的许可证,并将所述许可证提供给该作为第三人的第三客户端装置。 [0015] Thus, to solve the above problems occurring in the prior art and the present invention is made, and an object of the present invention is to provide a method for providing a license corresponding to the encrypted content to the client device using the method, and DRM conversion systems approach, that is, when carried out by the DRM conversion system converts DRM content is assigned to a third party over a third client device and the third received a license from the client device as a third person When requested, they will receive in response to the request for a license from the license corresponding to the type of server DRM encryption, and the license provided to the third party as a third client device.

[0030] 下面将参照附图解释根据本发明的优选实施例的用于向客户端装置提供对应于加密内容的许可证的方法以及使用该方法的DRM转换系统。 [0030] Examples will now be explained with reference to the accompanying drawings for providing a license corresponding to the encrypted content to the client device and a method of using the method DRM conversion system according to a preferred embodiment of the present invention.

[0031] 图2是表示根据本发明的实施例的DRM转换系统的网络连接关系的示意图。 [0031] FIG. 2 is a schematic diagram showing the connection relationship of the network according to an embodiment of the present invention DRM conversion system. [0032] 假设第一客户端装置202支持第一DRM类型,并且第二客户端装置205和第三客 [0032] assumed that the first client device 202 supports a first DRM type, and the second client device 205 and a third passenger

6户端装置206支持第二DRM类型。 6 client device 206 supports a second type of DRM.

[0033] 如图2所示,第一客户端装置202接收第一DRM类型的第一内容和对应于所述第一内容的第一许可证,并且再现所述第一内容。 [0033] As shown, the first client device 2 receives the contents of the first 202 of the first type and a first DRM license corresponding to the first content, and reproducing the first content. 这里,第一服务器201可以是提供第一DRM 类型的内容和许可证的服务器。 Here, the first server 201 may provide the server first type of content and DRM licenses.

[0034] 当客户端装置202的用户想要从第二客户端装置205再现第一内容时,DRM转换系统203对第一DRM类型的第一内容和对应于所述第一内容的第一许可证进行DRM转换, 以生成第二DRM类型的第二内容和对应于所述第二内容的第二许可证。 [0034] When a user wants to client device 202 from the second client device 205 reproducing the first content, DRM system 203 converts the first type of first DRM content and a first license corresponding to the content of the first DRM certificate be converted to generate a second DRM content and a second type corresponding to the second license to the second content. 在本发明的实施例中,第一客户端装置202和第二客户端装置205分别支持不同的DRM类型。 In an embodiment of the present invention, the first client device 202 and the second client device 205 support different types of DRM. 例如,所述第一DRM类型可以是MS-DRM,而所述第二DRM类型可以是OMA-DRM。 For example, the first DRM type may be MS-DRM, DRM type and the second can be OMA-DRM.

[0035] DRM转换将第一DRM类型的第一内容和第一许可证转换为中间格式,然后将该中间格式转换为第二DRM类型的第二内容和第二许可证。 [0035] DRM converting the first content of the first type and a first DRM license is converted to an intermediate format, and then converts the intermediate format to a second DRM content and a second type of the second license. 所述DRM转换已在韩国专利公开文献No. 2005-120579中详细说明。 The DRM conversion has been published literature in Korean Patent No. 2005-120579 in detail.

[0036] 另一方面,当第二客户端装置205将所转换的内容超分配给作为第三人的第三客户端装置206时,为了使用该内容,第三客户端装置206向DRM转换系统203发送对应于所述第二内容的许可证的请求。 [0036] On the other hand, when the second client device 205 over the converted content assigned to a third party when the third client device 206, in order to use the content, the third DRM client device 206 to the switching system 203 transmits a request of the second content corresponding to the license. DRM转换系统203收到所述许可证的请求,从第二服务器204 接收对应于超分配至第三客户端装置206的第二内容的第二许可证,并将该第二许可证发送至第三客户端装置206许可证。 DRM system 203 receives a request to convert the license, 204 receives the second license to the super distribution corresponding to the third client device 206 of the second content from the second server, and sends the second license to the first three client device 206 permits. 在本发明的实施例中,第二客户端装置205和第三客户端装置206支持相同的DRM类型。 In an embodiment of the present invention, the second client device 205 and a third client DRM device 206 support the same type.

[0037] 这里,所述超分配意味着单独分配内容和许可证。 [0037] Here, the super-distribution means that the content and distribution of a single license. 用户通过超分配能将自己使用的内容分配给第三人。 Content Users can assign their own use by ultra-assigned to a third party. 已接收到内容的第三人不考虑所述内容如何而获得许可证并使用所分配的内容。 Has received the third party does not consider the contents of the content to obtain a license and using the assigned content.

[0038] 这里,已请求许可证的第三客户端装置206能连同许可证请求一起向第一服务器201请求批准。 [0038] Here, has requested a permit third client device 206 can request together along with the license server 201 to the first request for approval. 当DRM转换系统203收到来自第三客户端装置206的许可证请求时,它能向第一服务器201请求相应内容的许可证颁发批准。 When the DRM license conversion system 203 receives a license request from a third client device 206, it can request the appropriate content server 201 to the first issue approval.

[0039] 当DRM转换系统203收到来自第三客户端装置206的许可证请求并且向第一服务器201请求相应内容的许可证颁发批准时,DRM转换服务器能辨别对应于所述内容转换之前的DRM类型的第一服务器201,在DRM转换服务器中通过查阅转换日志数据库来请求许可证。 [0039] When the DRM license conversion system 203 receives a request from a third client device 206 and 201 to the first server requests corresponding content licensing approval, DRM server can identify the corresponding conversion of the content before conversion The first type of DRM server 201, the DRM conversion server by referring to the conversion log database to request a license.

[0040] 也就是说,DRM转换系统203在每次DRM转换时将关于DRM转换的日志记录在转换日志数据库中。 [0040] In other words, DRM conversion system 203 at each DRM convert DRM conversion on logging in the conversion log database. 当DRM转换系统203收到特定内容的许可证请求时,通过查阅转换日志数据库,DRM转换系统203可以辨别对应于相应内容转换之前的DRM类型的DRM服务器。 When the DRM conversion system 203 receives the license request specific content, by referring to the conversion log database, DRM conversion system 203 may correspond to identify appropriate content prior to conversion of DRM types of DRM servers. [0041] DRM转换系统203可以包含DRM转换服务器和DRM转换客户端。 [0041] DRM conversion system 203 can include servers and convert DRM convert DRM client. 即,DRM转换系统203的部分配置可以包含在DRM转换服务器中,而其余配置可以包含在DRM转换客户端中。 I.e., DRM conversion system 203 may comprise part of the configuration in the DRM conversion server, and the remaining configuration may be included in the DRM client conversion. [0042] 在本实施例中,DRM转换系统203可以仅仅包括DRM转换服务器而没有DRM转换客户端。 [0042] In the present embodiment, DRM conversion system 203 may include only a DRM transformation server without DRM translating client. 在这种情况下,DRM转换服务器实现DRM转换系统203的所有功能。 In this case, DRM server implementations DRM conversion system converts all the features of 203. [0043] 根据本发明的客户端装置202、205和206中的每个可以包括PC,个人数字助理(PDA),智能电话,掌上电脑,便携电话,MP3播放器,诸如码分多址复用模块、蓝牙模块、红外线通信模块(IrDA)等的预定通信模块,有线/无线LAN网卡,并且可以安装用于实现多媒体再现功能的预定微处理器以完成预定的计算处理。 [0043] According to the present invention, the client device 202, 205 and 206 each may include PC, a personal digital assistant (PDA), smart phones, PDAs, mobile phones, MP3 players, such as Code Division Multiple Access module, Bluetooth module, infrared communication module (IrDA) and other predetermined communication module, wired / wireless LAN card, and can be installed microprocessor for multimedia reproduction function scheduled to complete a predetermined calculation process. [0044] 图3是表示根据本发明的实施例的DRM转换系统的处理方法的流程图。 [0044] FIG. 3 is a flowchart showing processing method according to an embodiment of the present invention the DRM conversion system.

[0045] 在步骤301中,DRM转换系统对第一DRM类型的第一内容和对应于所述第一内容 [0045] In step 301, DRM conversion system of the first type and the first DRM content corresponding to the first content

的第一许可证进行转换,从而生成第二DRM类型的第二内容和对应于所述第二内容的第二 Convert the first license, to generate a second DRM content and a second type corresponding to a second of said second content

许可证。 License. 例如,DRM转换系统可以转换第一DRM类型的第一内容"loved"和对应于第一内 For example, DRM conversion system can convert a first type of first DRM content "loved" and corresponds to the first

容"loved"的第一许可证,从而生成第二DRM类型的第二内容"loved"和对应于第二内容 Yung "loved" the first license, thereby generating a second type of the second DRM content "loved" and the content corresponding to the second

"loved"的第二许可证。 "Loved" the second license.

[0049] 在这种情况下,当对应于转换之前的DRM类型的服务器被取消时,并且对应于第二被分配内容的第二许可证被颁发时,将导致内容源的不当忽视。 [0049] In this case, when the DRM before conversion corresponding to the type of server is canceled, and the content corresponding to the second assigned when the second license is issued, will result in improper expense of content sources.

[0050] 在步骤303中,DRM转换系统根据所述许可证请求向第一服务器询问批准或不批准。 [0050] In step 303, DRM conversion system asked to approve the first server based on the license or not to approve the request. 即,由于所述许可证是通过转换对应于第一DRM类型的第一内容的第一许可证而获得的,并从第一服务器颁发第一许可证,因此DRM转换系统根据所述许可证请求询问批准或不批准。 That is, since the license is a license corresponding to the first by converting a first type of first DRM content is obtained, and a first license issued from the first server, so DRM conversion system in accordance with the license request asked to approve or disapprove. 此外,通过查阅记录有DRM转换日志的数据库,DRM转换系统能辨别第一服务器。 In addition, a review of records have DRM conversion log database, DRM conversion system can identify the first server. [0051] 在实施例中,DRM转换系统不根据所述许可证请求询问批准或不批准,而是作为第三人的第三客户端装置一方能连同许可证请求一起向第一服务器请求批准。 [0051] In an embodiment, DRM conversion system according to the permit request is not asked to approve or disapprove, but as a third party client devices along with a third person can permit request for approval along with the first server. 此时,DRM转换系统能将对应于转换之前的DRM类型的第一服务器信息提供给第三人一方。 At this point, DRM conversion system can correspond to convert DRM type before the first server information to a third party person. [0052] 当从第一服务器收到批准响应时(步骤304) , DRM转换系统向第二服务器请求对应于被超分配给作为第三人的第三客户端装置的第二内容的第二许可证(步骤305)。 [0052] When receiving the approval response from the first server (step 304), DRM conversion system corresponding to the second server request is assigned to a third party over a second content third client device of the second grant certificate (step 305). [0053] 在步骤306中,DRM转换系统从第二服务器接收对应于所超分配的第二内容的第二许可证,并将所述第二许可证发送至作为第三人的第三客户端装置。 [0053] In step 306, DRM conversion system from the second server receives the second license corresponding to the content of the second super distribution, and the second license is sent to a third party as a third client devices. [0054] 在本发明的实施例中,当DRM转换系统从第一服务器收到批准响应时,它能从第一服务器接收由作为第三人的第三客户端装置付帐的预定分配金额。 [0054] In an embodiment of the present invention, when the system receives approval of DRM converting a first response from the server, it can receive a predetermined amount assigned by a third party as a third pay for the client device from the first server. 而且,DRM转换系统可以将所分配金额的一部分提供给第二服务器。 Moreover, DRM conversion system can be provided as part of the allocated amount to the second server.
