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： The present invention relates to adding watermark information to film prints. This performed when duplicating an original film print (405) to an undeveloped copy film (407), where a surface of the original film print is positioned close to a surface of the undeveloped film. The surface of the undeveloped film is exposed with light transferred through the surface of the original film print. The watermark is obtained from a number of individually controllable light sources (411), such that the light transferred through the surface of the original film print (405) has a predefined pattern depending on how the light from the light source (409) is controlled. The invention further relates to a storage medium comprising instructions for performing the method of adding watermark information, a system for adding watermark information and a system for determining the legality of a film print copy.
摘要翻译：本发明涉及向胶片印刷品添加水印信息。当将原始胶片打印（405）复制到未打印的复印胶片（407）时，其中原始胶片打印件的表面位于未开发胶片的表面的位置。未开发的膜的表面暴露于通过原始胶片印刷表面的光。从多个独立可控的光源（411）获得水印，使得通过原始胶片印刷（405）的表面传输的光具有取决于来自光源（409）的光的控制的预定图案。本发明还涉及包括用于执行添加水印信息的方法的指令的存储介质，用于添加水印信息的系统和用于确定胶片打印副本的合法性的系统。

摘要： A method of and device for controlling import of content into a domain comprising a number of devices. The method comprises checking for the presence of a domain watermark in the content, and if the domain watermark is found in the content, refusing import of the content into the domain, and if the domain watermark is not found in the content, allowing import of the content into the domain and causing the domain watermark to be embedded into the content. Optionally, re-importing into the "original" domain might be allowed. In this embodiment the method further comprises refusing import of the content into the domain if the domain watermark is found in the content unless the identifier matches an identifier for the domain. Other payloads in the domain watermark can be used to e.g. implement location- or time-based restrictions on import.
摘要翻译：一种用于控制将内容导入包括多个设备的域的方法和设备。该方法包括在内容中检查域水印的存在，如果在内容中发现域水印，拒绝将内容导入到域中，并且如果在该内容中没有找到域水印，则允许导入内容进入域并导致域水印嵌入到内容中。可选地，可以允许重新导入“原始”域。在该实施例中，如果在内容中找到域水印，则该方法还包括拒绝将内容导入到域中，除非标识符与域的标识符匹配。域水印中的其他有效载荷可以用于例如实施进口定位或基于时间的限制。

摘要： A system (100) comprising a plurality of interconnected devices (101-105) and being arranged to provide the devices (101-105) conditional access to protected content items, characterized in that the system (100) is arranged to restrict the number of simultaneous sessions involving said protected content items to a predetermined total limit. Preferably the system (100) restricts the number of content items that can be accessed simultaneously to the predetermined limit. Security modules (300) such as smart cards can be used for this purpose. Each security module (300) may be arranged to restrict the number of content items to which it provides access simultaneously to an individual limit, which can change over time. The system restricts the sum of the individual limits to the predetermined total limit. If the limit is reached, further sessions may be refused or allowed at reduced quality level.

摘要： Items of media information are stored in separately reusable blocks of memory. Items are split into a plurality of layers, so that the item can be represented at reduced quality by a subset of the layers without using a remainder of the layers. Each layer is stored in a respective one of the blocks. When information of a subsequent item is stored, a block for storing the information of the second item dependent on a number of blocks that is in use for storing information. An unused block is selected when the number of blocks that is in use is below a threshold number. When the number is above the threshold number a block is re-used that was previously used for storing a layer from said remainder. Preferably, when the layers are encrypted, different layers of the first item are encrypted independently of one another, so that each layer can be decrypted even if the remainder has been overwritten.

摘要翻译：媒体信息的项目被存储在可重复使用的存储块中。项目被分割成多个层，使得可以通过层的子集以低质量来表示项目，而不使用层的其余部分。每个层存储在相应的一个块中。当存储后续项目的信息时，存储用于存储第二项目的信息的块，这取决于正用于存储信息的块的数量。当使用的块的数量低于阈值数时，选择未使用的块。当数量高于阈值数时，重新使用先前用于存储来自所述余数的层的块。优选地，当层被加密时，第一项目的不同层被彼此独立地加密，使得即使其余部分被覆盖也可以对每个层进行解密。

摘要： A method of enabling disintermediation in a business model, as well as an arrangement (100) therefor. Extra information related to the business model is embedded in content such as music, which is then distributed via a third party (202) to a rendering device (204). The rendering device (204) generates an audible signal (120) that can be picked up by a receiver (220) such as a mobile phone. The receiver (220) processes the signal (120) to obtain the embedded information, which is then used in the course of the business model.

摘要： A receiving device (110) for securely storing a content item (102) on a storage medium (111). The content item (102) is stored in a secure format, and has an associated license file. The license file (141) is encrypted using public key associated with a group of playback devices (120, 121), so that each playback device (121) in the group can decrypt the license file (141) and play the content item (102), but devices outside the group cannot. A playback device (121) can provide a device-specific public key to a Content Distribution Management System (CDMS). The CDMS then returns the secret key for the group encrypted with the public key of the playback device (121). The playback device (121) then securely obtains the secret key of the group and is subsequently able to decrypt the license file (141).
