Abstract: A method in a computing device includes: via a short-range interface of the computing device, detecting a plurality of beacons emitted by another computing device, each beacon containing an identifier of the other computing device; obtaining respective proximity indicators corresponding to the beacons; generating a first set of aggregated attributes from the proximity indicators; storing the first set of aggregated attributes in association with the identifier of the other computing device; and transmitting the first set of aggregated attributes to a server configured to detect physical proximity between the computing device and the other computing device based on the first set of aggregated attributes.
