Abstract
A scalable tag detection, location, tracking, recovery, and data collection system uses a social network of mobile devices, such as smartphones, as readers, to find lost or stolen goods that are tagged, or to read data or sensor values from tags at remote locations. A network service apparatus compiles IDs of tags of interest into a data structure representing a subset of all tagged items, and transmits the data structure information to the participating mobile devices. Each mobile device application can receive tag transmissions when in proximity to any tag. The mobile device processes received tags with the filter to determine if they are part of the composition of the data structure and thus a tag of interest. If so, the mobile device location, time, and tag ID, are relayed to the network service for additional analysis. The short range tag emits a low power, low duty factor signal.
