Abstract:
A personal authentication device includes: acoustic signal transmission means  701  for transmitting a first acoustic signal to a part of a head of a user; acoustic signal observation means  702  for observing a second acoustic signal which is an acoustic signal after the first acoustic signal propagates through the part of the head; acoustic property calculation means  703  for calculating an acoustic property from the first acoustic signal and the second acoustic signal; and user identification means  704  for identifying the user, based on the acoustic property or a feature value extracted from the acoustic property and relating to the user.

Claim (Index 2):
The personal authentication device according to  claim 1 , comprising\n a storage unit which stores beforehand, for at least one person, an acoustic property at a time of propagation of an acoustic signal through a predetermined part of a head of the person or a feature value extracted from the acoustic property, wherein the user identification unit identifies the user, by comparing the acoustic property calculated from the second acoustic signal with the acoustic property stored in the storage unit or comparing the feature value extracted from the acoustic property calculated from the second acoustic signal with the feature value stored in the storage unit.
