Abstract:
1. An authentication device including a detection section generating a signal, an authentication section that authenticates the identity of a person based on time-series data, and a sensor comprising: a detection circuit section for generating a signal a piezoelectronic element protruding therefrom, and an authentication section that authenticates the identity of a person based on time-series data representing variance in friction detected at the detection section, wherein said piezoelectronic element detects a fingerprint and variance in friction when relative movement between the piezoelectronic element and a finger occurs, said detection circuit section generates a signal representing a variance in friction between the piezoelectronic element and finger based on the detected fingerprint, and said authentication section authenticates the identity of a person based on time-series output volatage data representing variance in friction generated by the detection circuit section.
