A method of controlling operation of an inhaling device, the inhaling device comprising a gas flow path through which gas can be drawn by the action of a user puff, a gas flow sensor within the gas flow path and a memory, the method comprising: recording gas flow measurements from the gas flow sensor; comparing the gas flow measurements with the user puff signature stored in memory to provide a correlation score; and enabling or disabling further operation of the device based on a value of the correlation score. This method allows an inhaling device, such as an electrically operated smoking device or a medical inhaler to authenticate a user of the device based on a detected puffing behaviour. |
