Description

基于数字版权管理的内容对象下发方法及其系统技术领域本发明涉及数字版权管理(DRM, Digital Rights Management)技术领域, 尤其是涉及一种基于数字版权管理的内容对象下发方法及其系统。 BACKGROUND made based method and system of the present invention relates to the field of digital rights management (DRM, Digital Rights Management) DRM content object under, and particularly to a method and system based on the fat content of the digital rights management objects. 背景技术伴随着现代通信技术的不断发展,数字版权管理(DRM, Digital Rights Management)技术在通信终端上的应用程度越来越普遍,同时使得数字版权管理和内容计费问題也越来越突出。 BACKGROUND With the continuous development of modern communication technologies, digital rights management (DRM, Digital Rights Management) technology application degree in communication terminals and more common, while allowing digital rights management and content billing problems are more prominent. 而开放移动联盟(OMA, Open MobileAlliance) DRM规范通过基于客户端的DRM代理(DRMAgent)和版权发布者(RI, Rights Issuer )之间的版权对象获取协议(ROAP, Rights Object Acquisition Protocol)构建了OMA DRM的安全架构,保证了移动终端对基于DRM的内容对象的使用权限和安全性问题。 The Open Mobile Alliance (OMA, Open MobileAlliance) DRM specification constructed OMA DRM by obtaining copyright objects between client DRM agent (DRMAgent) and the rights issuer (RI, Rights Issuer) protocol (ROAP, Rights Object Acquisition Protocol) security architecture to ensure that the rights and security issues using mobile terminals based DRM content object. 在OMADRM中,内容对象(Content)是经过加密处理的,所以客户不能直接使用,要想对某内容对象(比如一首歌)进行使用,必须要获取对应该内容对象的版权对象(RO, Rights Object),该获取的RO中提供了对该内容对象的解密方法,并且同时规定了客户对内容对象的使用权限,客户在申请RO的过程中要遵从于ROAP协议。 In OMADRM, the content objects (Content) is encrypted, so the customer can not be used directly, in order for a content object (such as a song) for use, must acquire a rights object to be content object (RO, Rights object), RO which acquired a decryption method provides the content objects, and also provides the customers' access to content objects, RO customers in the process of applying the protocol to follow in ROAP. 通常在业务的实际运作中,客户对同一内容对象的消费方式可以有很多种(比如消费一次,不限量使用一周,或在同一域成员中使用等),其中不同的消费方式对应着不同的RO,而不同的RO则对应不同的计费策略。 Usually in the actual course of business, the customer can have on the consumption patterns of the same content objects are many (such as consumer once, unlimited use a week or in the same domain members, etc.), where different consumption patterns corresponding to different RO while the RO is different corresponding to different charging policies. 业务提供者可以通过制定新的消费方式以及费率等来吸引更多的消费者,从而提高业务竟争力。 Service providers can attract more consumers through the development of new consumption patterns and rates, so as to improve business competitiveness. 在内容计费方面,客户在使用相关内容过程中要支付两部分费用, 一部分是网络流重费,另一部分则;IJISL权使用费。 In terms of content billing, customers use the content during the two to pay part of the cost, is part of a network flow heavy fee, the other part; IJISL royalties. 通常内容发布者(CI, Content Issuer)和版权发布者(RI, Rights Issuer)主要关注的是版权使用费,但在具体业务运作中,客户在关注版权使用费的基础上,通常还要关注网络流量费。 Usually content publishers (CI, Content Issuer) and the rights issuer (RI, Rights Issuer) main concern is the copyright royalties, but in the specific business operations, customers on the basis of the focus on copyright royalties, usually also concerned about the network traffic charges. 也就是说, 客户在下载或分发内容对象之前,就应该清楚地知道要下栽的内容对象文件大小、该内容对象都有哪些消费方式以及不同消费方式下的费用是怎样计算的, 以便客户衡量及选择是否要下栽该内容对象。 In other words, the customer before downloading or distributing content objects, it should be well aware of the contents of the object to be tilted downward and crashed file size, what are the contents of the object of consumption and costs under different consumption patterns is how to calculate in order to measure customer and select whether you want the content object tilted downward and crashed. OMA DRM^范具体给出了基于DRM的内容对象基本下栽模式,如图l所示,为OMADRMM^范给出的第一种内容对象J^下栽模式的主要处理过程示意图,其主要实现过程如下:al.客户首先到CI上进行内容浏览,选择自身想要的内容对象(Content X) 及其对该Content X的消费方式;a2.客户端按照客户的选择下栽经过加密处理的ContentX,并保存在客户端本地;a3.其中客户端保存的Content X文本头中包含有对应RI的通用资源定位符(URL, Uniform Resource Locator)信息,客户会根据该URL地址信息连接RI,以ROAP协议发起用于解密ContentX的RO的申请处理;a4.RI在接收到客户的请求后,触发计费处理,并将对应的RO下发给客户; a5.客户在获取到RO后,基于该RO对下栽的ContentX进行解密使用。 The OMA DRM ^ given range based on the specific DRM content object substantially tilted downward and crashed mode, shown in Figure l, ^ tilted downward and crashed main processing mode is a schematic diagram of a first content object OMADRMM ^ J given range, to achieve its main as follows: al client first content to browse the CI, select the content object (content X) and the content X consumption patterns themselves want; a2 client in accordance with the customer's choice tilted downward and crashed through ContentX encryption processing. and stored locally on the client;. a3 wherein the stored client Content X text header contains the corresponding RI universal resource locator (URL, Uniform resource locator) information, the client connects RI based on the URL address information to ROAP application protocol initiates a process for decrypting an RO ContentX; a4.RI after receiving requests from a client, the accounting process is triggered, and the corresponding RO to the customer;. after a5 RO acquired customer, based on the RO the ContentX tilted downward and crashed to decrypt use. 如图2所示,为OMADRM^范给出的第二种内容对象M下栽模式的主要处理过程示意图,其主要实现过程如下:bl.客户预先在CI和RI上定购相关内容对象(ContentY)和对应的消费方式、以及用于解密该Content Y的RO, CI在定购条件满足时将客户定购的Content Y推送给客户;b2. RI在定购条件满足时将客户定购的RO推送给客户;b3.客户基于RI推送的RO对CI推送的ContentY进行解密使用。 2, the main process of the second content object OMADRM ^ M tilted downward and crashed given range mode schematic, the main process is as follows:. Bl customer previously ordered content objects (contentY) on the CI and RI and the corresponding consumption, and means for decrypting the Content Y is RO, when the order conditions are met CI customer ordered Content Y pushed to the client;. b2 RI when ordering the conditions of the customer orders to the client pushed RO; B3 customer RI-based push-RO to decrypt CI push ContentY use. 如困3所示,为OMA DRM^范给出的第三种内容对象M下栽模式的主要处理过程示意图,其主要实现过程如下:cl.客户预先在CI上定购相关内容对象(Content Z)和对应的消费方式, CI在定购条件满足时将客户定购的Content Z推送给客户;c2.客户端在ContentZ推送完成后,会自动向RI发起用于解密Content Z的RO申请处理;c3. RI在接收到客户端发来的请求时,下发对应用于解密ContentZ的RO给客户;c4.客户端基于RI下发的RO对CI推送的Content Z进行解密使用。 As shown trapped 3, a schematic view of the main process of the third OMA DRM ^ M tilted downward and crashed content object model given range, the main process is as follows:. Cl customer previously ordered content objects (Content Z) on the CI and corresponding consumption patterns, CI when ordering conditions are met the customer ordered Content Z pushed to the customer;. c2 client after ContentZ push is complete, the application will automatically initiate the RO process used to decrypt Content Z to RI; c3 RI. upon receiving the request sent by the client, delivers an RO to be applied to the client decryption ContentZ;. C4 client based on the RO issued by the RI pushed Content Z CI decrypt use. 同时,OMADRM规范还具体给出了基于DRM的分发模式用例,所谓分发模式是指一个客户将保存在自己客户端上的内容对象分发给其他客户使用的方式,如图4所示,为OMADRM规范给出的第一种内容对象分发模式的主要处理过程示意图,其主要处理过程如下:dl.对于已保存在设备Dl上的ContentX,可以通过本地连接或可移动存储媒介等将Content X转发给设备D3;d2,由于ContentXA经过加密的,且设备D1申请过的RO不能在设备D3上使用,所以设名。 Meanwhile, OMA DRM specification also shows the contents of the specific object based on the distribution mode DRM use cases, a so-called distributed mode refers to a client stored on their client available to other clients using the embodiment shown in Figure 4, for the OMA DRM specification a schematic view of a first main processing content object given distribution mode, the main process is as follows:. dl for ContentX saved on the device Dl can be connected via a local or removable storage media, etc. to the device forwards the content X D3; d2, since the RO ContentXA encrypted, and the requested device D1 can not be used in the device D3, so set name. 3要想对ContentX进行使用,必须要申请自己的RO,即设备D3要向RI申请用于解密Content X的RO;d3. RI对使用设备D3的客户进行计费,并将用于解密Content X的RO下发给设备D3。 3 in order to ContentX for use, must apply for their own RO, namely device D3 RI want to apply for decryption Content X of RO;. D3 RI to customers using devices D3 for billing, and will be used to decrypt Content X D3 to the device under the RO. 如图5所示,为OMADRM^L范给出的第二种内容对象分发模式的主要处理过程示意图,其主要处理过程如下:el.设备D2将已下栽保存的Content Y转发给设备D3,其中设备D2转发的Content Y中包含可直接预览的内容片断;e2.客户在设备D3上先对可预览的内容片断进行预览,然后决定是否购买该ContentY;e3.客户决定购买该ContentY,向RI申请用于解密ContentY的RO;e4.RI对使用设备D3的客户进行计费,并将用于解密ContentY的RO下发给设备D3。 5, a schematic view of the main process of the second content object distribution pattern OMADRM ^ L given range, the main process is as follows:. El device D2 which has been tilted downward and crashed saved Content Y forwarded to the device D3, wherein the device D2 forwarded content Y contains direct preview of the content segments;. e2 customer first to preview the piece of content preview on the device D3, and then decide whether to buy the contentY;. e3 customer decides to purchase the contentY, to RI ContentY application used to decrypt the RO; e4.RI to customers using the charging device D3 and D3 to the device for decryption ContentY under the RO. 如图6所示,为OMA DRM规范给出的第三种内容对象分发模式的主要处理过程示意图,其主要处理过程如下:fl.设备Dl将已下栽保存的Content Z转发给设备D2,其中设备D1转发的Content Y中包含有可预览的内容片断;f2.设备D2接收到ContentZ和其中包含的可预览内容片断后,发现该可预览的内容片断必须有相应的RO解密才能进行预览,于是设备D2向RI申请用于解密可预览内容片断的RO;f3. RI对使用设备D2的客户进行计费,并将用于解密可预览内容片断的RO 下发给i史备D2;f4.客户基于RI下发的RO在设备D2上对可预览内容片断进行解密预览,以决定是否购买该Content Z;f5.客户决定购买该ContentZ,向RI申请用于解密ContentZ的RO;伤.RI对使用设备D2的客户进行计费,并将用于解密ContentZ的RO下发给设备D2'从上述OMA DRM给出的Content基本下发模式和基本分发模式可以看出, 客户是预先在CI上选取 6, a schematic view of a third main processing content object distribution mode is given OMA DRM standard, the main process is as follows:. Fl Dl forwarding device that has been saved Content Z tilted downward and crashed to the device D2, wherein device D1 forwarded content Y contains preview content segments; after f2 device D2 receives the preview content segments ContentZ and contained therein, it was found that the preview content segments must have the appropriate RO decryption to preview, then application device D2 for the RI preview RO to decrypt the content segments;. f3 RI customers device D2 for charging and for the sent history i D2 apparatus decrypts the content segments preview RO;. f4 customer based issued by the RI RO carried out on the device D2 to preview the content decryption preview clips to decide whether to buy the content Z;. f5 customer decides to purchase the ContentZ, RI to apply for decryption ContentZ of RO; hurt .RI to use customer billing device D2, D2 and to the device for decryption at the ContentZ RO 'from the above-mentioned OMA DRM Content delivery mode given basic and fundamental distribution pattern can be seen, the client is pre-selected on the CI 下栽的Content,并选取使用该Content的消费方式, 这样客户一旦下栽了相关Content之后,就已经选定了使用该Content的消费方式,后续客户若要基于其他消费方式对该已下栽的该Content进行使用时,通常需要重新登录CI,以重新选择对该Content的消费方式,从而使客户更改消息方式对已下栽的Content进行使用存在操作不便性,进而使得客户更改已下栽Content的消费方式的灵活性存在欠缺。 Tilted downward and crashed the Content, and choose to use the Content consumption patterns, so that customers once the relevant Content tilted downward and crashed, has been selected consumption patterns of use of the Content, the follow-up to customers based on other consumption of the already tilted downward and crashed when the Content for use, often requires re-login CI, to re-select the Content consumption patterns, enabling customers to change the way the message has been tilted downward and crashed to the Content that the operation carried out using the inconvenience, thereby enabling customers to make changes to the tilted downward and crashed Content there is a lack of flexibility in consumption patterns. 同时从上述OMADRM给出的Conten漆本分发模式可以看出,不同设备之间在进行容量较大的Content分发处理时,是将整个已下栽的Content (包含或不包含可预览的内容片断)转发给其他设备,这样势必会浪费分发客户的网络流量费。 Meanwhile Conten paint distribution mode of the present analysis can be seen from the above OMADRM, when performing a large capacity Content distribution processing between different devices is tilted downward and crashed to have the entire Content (with or without pieces of content preview) forwarded to other devices, this is bound to waste the customer's network to distribute traffic charges. 发明内容本发明提出一种基于数字版权管理的内容对象下发方法,以解决现有技术中客户对已下发内容对象的消费方式进行更改时欠缺灵活性的问题。 The present invention provides a method of hair under the content object-based digital rights management, in order to solve problems when customers make changes to the content object has issued consumption prior art lacks flexibility. 相应的,本发明还提出了一种基于数字版权管理的内容对象下发系统。 Accordingly, the present invention also proposes a system set at the content object based on DRM. 为解决上述问题,本发明提出的技术方案如下:一种基于数字版权管理的内容对象下发方法,包括步骤:内容发布者将第一客户定购的内容对象下发给第一客户,并将与该第一客户定购的内容对象对应的各个消费方式信息下发给第一客户。 To solve the above problems, the present invention proposes the following technical solution: a method based on the issued DRM content object, comprising the steps of: the content publisher will send the first client at the first client ordered the content object, and with the first information sent to customers under various consumption patterns of the first customers to order content object corresponding. 较佳地,所述方法还包括步骤:内容发布者将各个消费方式所对应的价格信息分别下发给第一客户。 Preferably, the method further comprising the step of: the content publishers price information corresponding to the respective consumption are sent to the first client. 较佳地,内容发布者将所述各个消费方式信息及对应的价格信息形成列表形式下发给第一客户。 Preferably, content publishers to the respective consumption price information and the corresponding information is formed delivers the first client list. 较佳地,内容发布者将所述各个消费方式信息及对应的价格信息承载在第一客户定购的内容对象文本头中,同第一客户定购的内容对象一并下发给第一客户.,较佳地,所述方法还包括步骤:第一客户在内容发布者下发的各个消费方式中选取一种消费方式,并基于选取的消费方式向版权发布者请求对应该消费方式的版权对象;
