1. A method of determining a measure of proximity between a first device that is mobile and a second device, the method comprising:
obtaining a first device signature comprising an indication of a first point in time and a first parameter associated with the first point in time, wherein the first parameter is characteristic of a first measurement performed by a first sensor comprised in the first device;
obtaining a second device signature comprising an indication of a second point in time and a second parameter associated with the second point in time, wherein the second parameter is characteristic of a second measurement performed by a second sensor comprised in the second device; and
determining, based on the first device signature and the second device signature, the measure of proximity between the first device and the second device.
