Abstract
The method of proximity detection between a first and a second device (DVC, DVC), carried out by the first device (DVC), comprises the steps of collecting a first information on exposure of the first device (DVC) to electromagnetic waves; receiving a second information on exposure of the second device (DVC) to electromagnetic waves from the second device (DVC); determining a matching information between the first information on exposure and the second information on exposure and detecting either proximity or non-proximity between the first and the second device (DVC, DVC) based on the matching information.
