Abstract
Authentication of a user wearing a head mounted display using wireless channel characteristics, such as wireless channel sounding, is disclosed. A transmission signal from a signal transmitter passes over the face or other parts of the head of the user and is received by a signal receiver, also in, at or near the head mounted display. The input signal received is processed according to the known transmission signal that was transmitted to obtain wireless channel characteristics. Based on these wireless channel characteristics a signal signature is identified, for example, using a machine learning based embedding technique. If the signal signature thus determined matches a signal signature previously associated with the user then the user is authenticated. User access to a resource or action may then be granted automatically.
