Abstract
Entity identity information and location identity information are sensed and made available to subscriber applications through a secure location-aware services infrastructure, thereby allowing for the creation of location-based services. Information detected by a sensor is passed to an interface aggregator for conversion to a standardized format and then forwarded to location registers for the domain of the sensors. Subscriber applications query the registers to determine which entities are in a particular location and to determine the location of entities. By unifying diverse sensing technologies, location information can be simultaneously obtained on varying degrees of granularity. In addition, the system is scalable to large scenarios by using a plurality of sensors, interface aggregators, and registers.
