Abstract: A location tracking unit for use with a location based service system is presented. The location tracking unit comprises: a navigation receiver adapted to implement a location tracking function; data processing means adapted to determine an occupied location according to a first location matching process, the first location matching process using navigation data from the navigation receiver and a first set of geographic data; and data processing means adapted to verify the integrity of the first location matching process based on a second location matching process using navigation data and a second set of geographic data.

Abstract: A UPnP-compliant MediaRenderer-Control Point combination is enabled to exploit an organizational context of a content item as represented in a UPnP Content Directory Service. To this end, the combination is enabled to receive a URI representative of a Content Directory Service description, together with an objectID representative of the content item.

Abstract: A system implements a secure transaction of data between a server and a remote device. The remote device comprises: processing means adapted to process input data according to a security process; data storage means adapted to store verification information derived from the input data according to an encryption algorithm; and communication means for communicating the input data which has been processed by the security process to the server. The server is adapted to transmit a verification request to the remote device, and to verify the integrity of the security process based on verification information received from the communication means of the remote device in response to the verification request.

Abstract: Bandwidth use between an access provider system (14) and a user computer (10) is adapted to an amount of subscription quotum that has been used by a subscriber. Quotum use information is representative of an amount of data that has been exchanged between the user computer (10) and an access provider system (14) since a predetermined time point. A request is received for retrieving media information from the network (16) and for rendering that media information at the user computer (10). In response to the request a selection is made between a plurality of versions of the requested media information, dependent on the quotum use information. Different versions require respective different data rates for transmission from the access provider system (14) to the user computer (10). The more quotum has been used, the lower the data rate of the selected version.
