Abstract
Co-location of devices is determined by receiving at a query engine from a device, a remote audio signature and associated remote device identification and device location data and comparing in the query engine remote audio signatures stored in a database to the remote audio signature. The remote database further stores remote device identification and device location data associated with the stored audio signatures. The query engine only performs the comparisons for remote audio signatures that have the same location data. The query engine thereby limits its query set of remote audio signatures in the database. A processor reports a remote device identification associated with the remote audio signature of the device received over the communication channel and the remote device identification associated with the stored remote audio signature when an audio signature received over the communication channel matches an audio signature stored in the database within a threshold confidence level.
