Abstract
A method for recognising a user whose body is capable of re-transmitting an electromagnetic signal in the form of an electromagnetic wave. The method is implemented on a transceiver device and includes the following steps on the device: transmitting an electromagnetic pulse signal; obtaining a re-transmitted signal when the user is in the vicinity of the device, the signal depending on the transmitted pulse signal; comparing the re-transmitted signal with at least one reference signal of the user; and recognising the user if the re-transmitted signal is close to the reference signal.
