Abstract: An apparatus and method for authenticating a user of a vapour generating system include emitting a transmitted signal from a mouthpiece of the system into an oral cavity of the user and detecting a received signal that includes reflections of the transmitted signal from the tongue of the user. The received signal is analysed to derive characteristics of it that include Doppler shifts resulting from the tongue moving towards or away from the receiver. Operation of the system is enabled only if the user moves their tongue in a predetermined pattern, for example by inaudibly speaking a password, so that the derived characteristics match corresponding characteristics of the authorized user that have been stored in a preliminary training step. The predetermined pattern of movement of the tongue is not easy for an unauthorized person to detect or to reproduce. The transmitted signal may be a high frequency acoustic signal.
