In another embodiment, the specific signal may be an ultrasonic signal.

The signal detector 120 may be electrically isolated from the signal generator 110. The signal detection unit 120 may be configured to receive a signal output from the signal generation unit 110 through the touched finger. The signal detecting unit 120 may be configured to detect a distortion of a bio-signal transmitted through a finger. The bio-signal can be distorted depending on the structure of the finger, the constituent material, etc. during transmission through the finger. The signal detector 120 can detect the distorted signal.

The finger recognition unit 130 may be implemented to store and / or compare the detected bio-signals. When a new signal is input, the finger recognition unit 130 can recognize the user authentication, that is, the finger of the user, by comparing the input signal with the stored signal information. That is, when a new signal is input, recognition security can proceed by analyzing whether it is a signal having the same characteristics as those of the stored finger.

In an embodiment, the finger recognition unit 130 may store signal information about a finger of a single user. In another embodiment, the finger recognition unit 130 may store signal information for a plurality of users' fingers.
