摘要： The present invention relates to methods, devices, computer program products as well as a signal for providing privacy to a user in relation to data, which data can be a content identifier (cr_id) for identifying content. For that reason a usage right certificate (UR) generated in relation to the data, includes the data (cr_id), concealed user identifying information (for example by using (H(PK//RAN)) and random data (RAN)) enabling the verification of the user identity in the user identifying information. In this way a user is guaranteed privacy in relation to information, such as content he has purchased.
摘要翻译：本发明涉及方法，设备，计算机程序产品以及用于向用户提供关于数据的隐私的信号，哪些数据可以是用于识别内容的内容标识符（cr_id）。为此，相对于数据生成的使用权证书（UR）包括数据（cr_id），隐藏的用户识别信息（例如通过使用（H（PK // RAN））和随机数据（RAN））使能在用户识别信息中验证用户身份。以这种方式，用户可以保证与信息有关的隐私，例如他购买的内容。

摘要： Methods of and devices (D1) for authorizing an operation requested by a first user (P2) on a content item (C1) in accordance with a user right (UR1). The user right may identify the first user or a second user (P) and authorizes the user in question to perform the requested operation on the content item. If the user right identifies the second user, the operation is authorized upon receipt of information linking a user right of the first user and the user right of the second user. Preferably the information comprises one or more domain certificates (DC1, DC2) identifying the first and second users as members of the same authorized domain (AD). Preferably a content right (CR1) enabling the operation is used, whereby the user right authorizes the second user to employ the content right.
摘要翻译：用于根据用户权限（UR 1）授权第一用户（P 2）对内容项目（C 1）请求的操作的方法和设备（D 1）。用户权限可以识别第一用户或第二用户（P）并授权有问题的用户对内容项目执行所请求的操作。如果用户权利识别第二用户，则在接收到链接第一用户的用户权限和第二用户的用户权限的信息时，操作被授权。优选地，信息包括将第一和第二用户标识为相同授权域（AD）的成员的一个或多个域证书（DC 1，DC 2）。优选地，使用启用该操作的内容权限（CR 1），由此用户权限授权第二用户使用内容权限。

摘要： The present invention relates to a method and a system for performing digital rights management. The idea of the invention is that a master right associated with a content is stored at a first authorised device (211). An authorised device is a device which can be considered trusted and performs actions with contents according to the associated rights. These devices enforce rights that are bound to contents, and perform the security tasks of the DRM system employed. A subright is derived from the master right, which subright controls what type of access a second authorised device (261) is given to the associated content. Finally, the subright is distributed to the second authorised device, given that the second device complies with predetermined distribution criteria associated with the master right. The device distributing the subright authenticates the device which is to receive the subright, ensuring that the second device can be trusted.

摘要： A method of providing conditional access to a content item, which content item is protected by a particular security mechanism, comprising providing unconditional access to a sample content item (105) protected by the same particular security mechanism. The sample content item (105) could be e.g. a trailer for the content item (104). Preferably the protected content item (104) is formatted using a particular formatting scheme like MPEG-2, and the sample content item (105) is formatted using the same formatting scheme. If acquisition of rights by a client (120) is necessary for playback of the content item (104), this is preferably refused until the sample content item (105) has been accessed by said client (120).

摘要： This invention relates to a method of processing rights relating to content, that can be communicated between devices. Typically, a Digital Rights Management (DRM) system imposes limitations of use and distribution, imposed by the service provider, content provider or distributor. The method of the invention renders it possible for a user who has received DRM rights to restrict the right further. The invention is more particularly related to the receipt of DRM rights to Authorized Domain Digital Rights Management (AD-DRM) systems and the introduction of user attributed rights in the form of further restrictions introduced to the received DRM rights. The invention further relates to a Rights Program Template (RPT) facilitating the introduction of such further restrictions in a user friendly way. Finally, the invention relates to a system supporting the method of the invention.
摘要翻译：本发明涉及处理与内容有关的权利的方法，其可以在设备之间进行通信。通常，数字版权管理（DRM）系统施加了由服务提供商，内容提供商或经销商施加的使用和分配的限制。本发明的方法使接收DRM权限的用户进一步限制权限成为可能。本发明更特别地涉及对授权域数字权限管理（AD-DRM）系统的DRM权限的接收以及引入到所接收的DRM权限的进一步限制形式的用户归属权限的引入。本发明还涉及一种以便于用户友好的方式促进进一步限制的权利计划模板（RPT）。最后，本发明涉及一种支持本发明方法的系统。

摘要： A broadcast data stream that contains a stream of encrypted data and a stream of messages. Data in successive segments of the stream of encrypted data is decryptable with successive decryption information from the messages. The stream of encrypted data is stored upon reception. The items with decryption information for the encrypted data are stored independently retrievable from the stream. Additionally synchronization information is generated and stored to link respective points in the stored stream of encrypted data to respective ones of the items with decryption information. During replay of a stored part of the stream of encrypted data the items with decryption information for the points in said stored part are retrieved. The retrieved items with decryption information are combined with the stream during replay at times selected under control of the synchronization information. The stream is fed to a decoder and the decryption information is combined with the stream by feeding the decryption information to a secure device, which in response to the decryption information feeds control words to the decoder.
