Claim:
1. An apparatus for determining co-location of devices comprising: a receiver connected to a communication channel configured to receive from a device over the communication channel: a database including: a query engine connected to said database configured to compare the one or more stored remote audio signatures to the remote audio signature received over said communication channel, wherein the query engine only performs the comparisons for remote audio signatures that have the same network location, the query engine thereby limiting its query set of remote audio signatures in the database; and a processor responsive to said query engine configured to report 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 said communication channel matches an audio signature stored in said database within a threshold confidence level, wherein the reported remote device identifications identify likely co-located devices without attributing the device location data or device location of one device to the device location data or device location of another device.
