摘要： The invention proposes a method to provide privacy for users or a user from a group of users with respect to authorizations they are granted, where such authorizations are expressed using digital authorization certificates, and with respect to domain certificates in case of groups of users. The idea is to conceal the user identity in the certificates, while the certificate itself remains in the clear. In this way, certificates can be widely and openly available, e.g. in a public network, without a random observer being able to link a user to an authorization or to identify a user within a domain. Privacy is also provided towards the certificate verifier by means of zero-knowledge protocols, which are carried out between the user and the verifier in order for the verifier to check a user's entitlement to a certificate. Privacy is further provided towards the certificate issuer as well, by means of a mechanism that allows the anonymous (buying or) issuing of certificates from the issuer.

摘要： A method of providing automatically verifiable trust in a content resolution process in which a PDR resolves a content reference identifier (CRID) identifying a content item using a resolution authority record (RAR) to obtain a locator identifying a location where the PDR can obtain the content item. Preferably, the measure comprises computing a digital signature over at least part of the contents of the CRID, the locator and/or the RAR. The method may also comprise encrypting at least a data portion of the CRID, RAR or locator. Digital rights needed to access the content item can be provided with the CRID, RAR or locator.

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 authorized device (211). An authorized 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 authorized device (261) is given to the associated content. Finally, the subright is distributed to the second authorized 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 and system for digital rights management, in which access to a piece of content is granted in accordance with a license owned by a license owner to a client who is a member of a domain. This requires successfully verifying that a membership relation exists between the client and the domain as reflected in a first state variable, and that an association relation exists between the license owner and the domain as reflected in a second state variable. Both relationships are revoked by executing an online protocol between the parties in the relationship after which both remove the corresponding state variable. The domain controller propagates the state administration relating to the domain is propagated to the client so that the client can update its state administration.

摘要： A conditional access system for controlling the access of receivers of end-users to data content transmitted from a data content source in an uplink system. The uplink system scrambles the content supplied from the content source, generates entitlement control messages containing a control word and an entitlement identification, and transmits the scrambled content and the entitlement control messages. A descrambler, an entitlement control message decoder and storage for recording entitlement identifications are associated to the receiver. The entitlement control message decoder supplies a control word to the descrambler for descrambling a part of the received scrambled content for which the receiver is entitled, if a match between the entitlement identification in the entitlement control message and the recorded entitlement identification exists. The content is subdivided into scenes having their own scene identification. The uplink system incorporates the scene identifications in the entitlement control messages.

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 person (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 the Authorized Domain (100) is obtained. In this way, access to a content item of an authorized domain by a person operating a device is obtained either by verifying that the content item and the person are linked to the same domain or by verifying that the device and the content item are linked to the same domain. Thereby, enhanced flexibility for one or more persons 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.
