1. A device for authenticating a user, comprising:
microphone circuitry configured to capture an ambient sound over a predetermined period, and
controller circuitry configured to:
measure the energy of the ambient sound over a predefined period;
compare the time series of the measured energy with a received time series of the measure of the energy of the ambient sound from a second device known to be close to the user, wherein the measured energy includes no personal information from the ambient sound; and
authenticate the user of the second device as the user of the device in the event of a positive comparison.
