WIPO Patent Application WO/2015/188723
Kind Code:
A1
Abstract:
A proximity relation is determined in various example embodiments. A method can comprise: acquiring a proximity relation between devices and at least one visible light source associated with each device of the devices in at least one moment; and determining a proximity relation of the devices according to the proximity relation between the devices and at least one visible light source associated with each device of the devices in at least one moment. A solution is thus provided for determining a proximity relation without acquiring actual geographic locations of the devices, which improves security and protects user privacy.
