Abstract:
1. A method for assisting in processing a plurality of incoming data streams, the plurality of incoming data streams comprising a first data stream that specifies one or more locations of a mobile user at one or more times and a second data stream that specifies one or more values of a monitored attribute at a location of interest at one or more times, the method comprising: delivering a location-centric trigger to a location-based information monitoring system, the location-centric trigger specifying at least one spatial predicate condition relevant to the location of interest and at least one non-spatial predicate condition relevant to the location of interest; receiving a safe region from the location-based information monitoring system, the safe region comprising at least one of the one or more locations whose probability of satisfying the spatial predicate condition falls below a first predefined threshold, wherein the safe region comprises a rectangle having a maximum weighted perimeter; processing a current location of the mobile user against the safe region; and delivering the current location to the location-based information monitoring system only if the current location lies outside of the safe region, wherein at least one of: the delivering the location-centric trigger, the receiving, the processing, or the delivering the current location is performed using a processor.
