摘要： To ensure that digital rights cannot be forged or tampered with, they can be digitally signed. However, this means that updating the digital rights is no longer possible, as this would invalidate the digital signature. The present invention proposes that the issuer of digital rights issues rights which are signed in elementary pieces, rather than as a whole. Rather than issuing a right to play back a piece of content three times, the provider issues for example three rights to play back the content once in a particular AD, of which two may be transferred to other domains. The digital rights are individually protected by signatures and it is no longer possible to forge digital rights. As an enhancement the rights that can be transferred are indicated as such and stored securely to prevent tampering. When the right is transferred, it must be signed by the person who originally received it.
摘要翻译：为确保数字权利不能被伪造或被篡改，可以进行数字签名。然而，这意味着不再可能更新数字版权，因为这将使数字签名无效。本发明提出数字版权发行人的签发单位，而不是整体签字。提供者不是发布三次播放内容的权利，而是在特定广告中提供三个权利，例如播放内容一次的三个权限，其中两个可以转移到其他域。数字权利由签名单独保护，不再可能伪造数字版权。作为增强，可以转让的权利被这样表示并被安全地存储以防止篡改。当权利被转移时，必须由最初收到的人签名。

摘要： This invention relates to a system and a method of generating an Authorized Domain (AD) by selecting a domain identifier, and binding at least one user (P1, P, PN1), at least one device (D1, D2, . . . , DM), and at least one content item (C1, C2, . . . , CNZ) to the Authorized Domain (AD) given by the domain identifier (Domain ID). Hereby, a number of verified devices (D1, D2, . . . , DM) and a number of verified persons (P1, P2, . . . , PN1) that is authorized to access a content item of said Authorized Domain (100) is obtained. In this way, access to a content item of an authorized domain by a user operating a device is obtained either by verifying that the content item and the user is linked the same domain or by verifying that the device and the content item is linked to the same domain. Thereby, enhanced flexibility for one or more users when accessing content in an authorized domain is obtained while security of the content is still maintaining. This is further done in a simple, secure and reliable way.

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： A method of verifying the authenticity of an image (1) rendered on a display screen (10) involves using a graphical representation of an authentication code (2) associated with the image. The graphical representation of the authentication code is also rendered on the display screen, while optional guide marks (3) may also be displayed. Both the image (1) and the associated authentication code (2) are read using a scanner (20), preferably a handheld linear scanner. The scanner calculates an authentication code based upon the image and compares the calculated authentication code with the authentication code read from the display.

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： A device (1) for decrypting encrypted images comprises an array of sensor elements (11) for sensing a first image, for example an encrypted image, and an array of display elements (12) for displaying a second image, for example a decrypted image. At least some display elements comprise integrated sensor elements, thus reducing the number of parts of the device. The integrated display/sensor elements (13) may be constituted by polymeric LED elements. The sensor function of the integrated elements may also be used for positioning the device relative to a terminal, and/or for checking a biometric feature of the user.

摘要： A method of generating a common secret between a first party and a second party, preferably devices (101-105) in a home network (100) that operate in accordance with a Digital Rights Management (DRM) framework. The devices calculate the common secret by evaluating the product of two polynomials P(x, y) and Q(x, z) using parameters previously distributed by a Trusted Third Party (TTP) and parameters obtained from the other party. Preferably the parties subsequently verify that the other party has generated the same secret using a zero-knowledge protocol or a commitment-based protocol. The method is particularly suitable for very low power devices such as Chip-In-Disc type devices.
摘要翻译：优选地，在第一方和第二方之间生成公共秘密的方法，优选地根据数字版权管理（DRM）框架操作的归属网络（100）中的设备（101-105）。这些设备通过使用先前由可信第三方（TTP）分发的参数和从对方获得的参数来评估两个多项式P（x，y）和Q（x，z）的乘积来计算公共秘密。优选地，各方随后使用零知识协议或基于承诺的协议来验证对方已经生成了相同的秘密。该方法特别适用于非常低功率的器件，例如片内盘式器件。
