    摘要： This invention relates to a system and method of providing conditional access to a data content item for a number of users, where the data content item is associated with a digital right that provides a user the right to access the data content item a predetermined number of times. The data content item is arranged in a number of subparts and the digital right is arranged in a number of sub-rights (100), initially designated as available sub-rights (101), where each available sub-right (101) provides a user the right to access a subpart of the data content item. When a user is granted (new) access to a content item a number of available sub-rights (101) is reserved. In this way, it is ensured in a very simple way that if a user in a multi-user scenario pauses access (also for a prolonged time) to the data content item then there will be sub-rights available so that the content may be accessed at a later time even if another user of the group starts spending sub-rights immediately after.

    摘要： This invention relates to a method and a system for evaluating proximity. A reference object is moved such that it enters at least two different proximity areas of two different proximity indicators, whereby proximity indications are generated. The time difference between the indications is measured. If the time difference is within predefined range it is ascertained that the reference object is within a well defined area. Thus, the fact that the speed of movement of a physical object is significantly limited is used for obtaining reliable proximity evaluations.

    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： There is provided a system operable to execute automatic synchronization therein. The system comprises a first data memory (20) for storming a first data set, said first memory (20) being coupled to a communication network (10). The system further includes a portable device (100) including a second data memory (130) for storing a second data set, said portable device being provided with a wireless transceiver (150) wherein said transceiver (150) includes a data memory (320) for storing a record of synchronization updates required to synchronize the first and second data sets into mutual conformity. The transceiver (150) is operable when introduced together with the portable device (100) within communication range of the communication network (10, 30a) to at least partially synchronize automatically said first and second data sets.

    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.
