向客户端装置提供对应于加密内容的许可证的方法及使用该方法的数字版权管理转换系统 Provide encrypted content corresponding to license the method to the client device using the same method of DRM conversion system

技术领域 Technical Field

[1]本发明涉及数字版权管理(下文称作'DRM,)。 [1] 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第三人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 providing a client device corresponding to the encrypted content licenses, which can respond to the content and ultra-assigned to a third party a corresponding license in DRM conversion system providing a license authentication request, also relates to the method of the DRM conversion system.

背景技术 Background

[2]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、广播或报纸己被数字化。 [2] With the development and popularization of computer technology, most in analog form production, preservation and management of business transactions subject matter of copyright, such as books, comics, music, film, radio or newspapers have been digitized.

[3]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。 [3] Although the digital 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 copyright subject matter is also easy to transfer and distribute 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 high speed digitized.

[4]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。 [4] However, in digital form, these advantages will be a factor copyright infringing author and subject matter of 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。 Since identical copies of the original, so that the wishes of the original purchase weaken, and to modify and copy could not be agreed by the author becomes very simple, it is easy to steal, transport, and distribution of copyrighted subject matter. 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。 Thus, the law of copyright object immediately spread on the Internet, the result is that they can not be controlled from the law.

[5]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。 [5] This negative factor in reducing the author's enthusiasm, and can reduce the production of the subject matter of copyright will. 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 authors 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, the digital copyright subject matter, the need for a technical protection device can effectively manage copyright, taking full advantage of digital technology has brought guaranteed.

[6]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。 [6] Therefore, in order to protect digital copyright subject matter interests and rights, we proposed a DRM technology applied to digital content. 而且,各种DRM类型已被使用。 Furthermore, various types of DRM has been used.

[7] 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。 [7] 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 the content and send and transfer the license to the 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 to decrypt the content and use of the content of information as the content usage rights.

[8]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。 [8] On the other hand, in the related art, the client device only reproduces and outputs a predetermined DRM types of content. 而且,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。 Moreover, in the same way, through the application of a DRM server type to provide content to the client device.

[9]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例的视图。 [9] FIG. 1 is a related art for the application of DRM content to the view of an embodiment of the method of the client apparatus.

[10]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。 [10] The client apparatus 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 to provide content request to 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IIO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。 Client device IIO license request to correspond to the first type of DRM licensing server 120, in order to achieve the above-mentioned encrypted content copyright protection. 在客户端装置IIO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 IIO server 120 received from the licenses issued by the licensing, you can use the content. g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。 g Jie, the client device 110 uses the decryption key included in the license and decrypts the encrypted content, the reproduction and output.

[11]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。 [11] Because of the type provided by the pre-DRM encrypted content based on the first server-related technologies 120, and therefore can not be provided by other types of DRM encrypted content.

[12]此外,在图1中,在用户使用客户端装置IIO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IIO传送至第二客户端装置130。 When [12] In addition, in FIG. 1, the user using the client device while reproducing content IIO, when a user uses DRM support a second type of the second client device 130 to reproduce the same content, he can above from client means IIO sent 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110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 DRM type is different from the type of DRM client device 110 supports, and therefore can not be reproduced from the client device to the second client device IIO content 130.

[13]为了解决这种问题,韩国专利公开文献No.l0-2005-0120579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。 [13] In order to solve this problem, Korean Patent Publication No.l0-2005-0120579 has introduced a support DRM content between different types of input and output device configuration. On

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。 Mentioned patent document discloses advantage that it can convert the contents of DRM by and between different types of DRM types of equipment. 然而,当将转换了DRM类型的内容超分配给第三人时,由于第三人没有用于相应内容的许可证,因此第三人不能再现所超分配的内容。 However, when the conversion of DRM types of content ultra assigned to a third person, the third person since the license is not used for corresponding content, so the third person can not reproduce the distribution of content over.

[14]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第三人时,可使该第三人能获得许可证。 [14] Thus, a method can be achieved when the converted DRM type of content being super assigned to a third person, the third person can get 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。 Before conversion corresponding to the DRM server can participate in an appropriate license to provide users with the freedom to ultra distributing content. 同时, 要求DRM转换系统能控制被超分配的内容的许可证。 At the same time, requiring DRM conversion system is able to control the distribution of content over the license.

发明内容 DISCLOSURE

[15]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第三人并收到来自所述第三人的许可证请求时,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第三人。 [15] Thus, in order to solve the above problems occurring in the prior art, the present invention is proposed, and an object of the present invention is to provide a method for providing content corresponding to an encryption key to the client device and the use of the method When the DRM conversion system approach, that is, when carried out by the DRM conversion system converts DRM content is super-assigned to a third party and received a license request from the third person, will respond to the license request received from DRM encryption corresponding to the type of license server, and the license provided to the third party.
