Abstract: An access control system uses an existing file format standard, e.g. for personal data interchange (PDI) or image file interchange, for novel access control purposes to provide temporary access for a wireless key device to a lock device and its protected environment by creating appropriate temporary access defining data in a data object compliant with the file format standard and communicating the data object to the lock device via the wireless key device.

Abstract: A data processing apparatus, a method and computer program product for comparing a first object associated with said data processing apparatus with a second object associated with a remote data processing apparatus, are provided. The data processing apparatus comprises an input device operable to accept a first and a second set of data associated with said first object. Said first set of data describes said first object, and said second set of data describes a third object. Additionally, the data processing apparatus includes a memory. Said memory is adapted to store said first and said second set of data. The data processing apparatus further comprises a receiver. Said receiver is adapted to obtain a first subset of a third and a fourth set of data, respectively, from said remote data processing apparatus. Said third and said fourth set of data is associated with said second object, and said third set of data describes said second object, and said fourth set of data describes a fourth object.

Abstract: A portable communication apparatus for match-making with a plurality of remote communication apparatuses has memory means for storing first match-making data associated with the portable communication apparatus. The portable communication apparatus also has a transceiver for communication with an individual one of the remote communication apparatuses across a wireless link, so as to receive second match-making data associated with the individual remote communication apparatus. The wireless link is based on an apparatus-specific identity of the port able communication apparatus as well an apparatus-specific identity of the individual remote communication apparatus.

Abstract: A portable communication apparatus for match-making with a plurality of remote communication apparatuses has memory means adapted to store match-making data, including local match-making data associated with the portable communication apparatus. A transceiver is adapted for wireless communication with a first remote communication apparatus, so as to transmit the local match-making data to the first remote communication apparatus, as well as to receive first remote match-making data associated with the first remote communication apparatus. A processing device is adapted to perform a correlation analysis between the local match-making data and the first remote match-making data and—in case a result of the correlation analysis indicates a match between the portable communication apparatus and the first remote communication apparatus—provide an alert to a user of the portable communication apparatus.
