Abstract

A multi-modal type wearable user authentication apparatus includes a housing; an electrode plate disposed at a rear surface of the housing to contact a user wrist; a display panel disposed at a front surface of the housing; and a multi-modal type user authentication sensor including mutually separated first and second electrodes disposed at the lower end of the display panel and constituting an edge and a bio recognition module disposed at the center.

First claim

What is claimed is:

1 . A multi-modal type wearable user authentication apparatus, comprising:
a housing; an electrode plate disposed at a rear surface of the housing to contact a user wrist; a display panel disposed at a front surface of the housing; and a multi-modal type user authentication sensor comprising mutually separated first and second electrodes disposed at the lower end of the display panel and constituting an edge and a bio recognition module disposed at the center.

2 . The multi-modal type wearable user authentication apparatus of claim 1 , wherein the first electrode is disposed in a direction of the display panel and has an upper portion coated with an insulating material in order to prevent interference from occurring due to a finger contact.

3 . The multi-modal type wearable user authentication apparatus of claim 2 , wherein the first electrode corresponds to a reference electrode using when sensing a bio signal formed through the electrode plate and the second electrode.

4 . The multi-modal type wearable user authentication apparatus of claim 1 , further comprising a switch disposed at the lower end of the first electrode to detect a finger pressure.

5 . The multi-modal type wearable user authentication apparatus of claim 4 , further comprising a control module included within the housing and that receives a fingerprint acquired through the bio recognition module and a bio signal acquired through the electrode plate and the first and second electrodes, when the finger pressure is detected.

6 . The multi-modal type wearable user authentication apparatus of claim 5 , wherein the control module analyzes a correlation between the received fingerprint and the received bio signal to perform user authentication.

7 . The multi-modal type wearable user authentication apparatus of claim 6 , wherein the control module determines effectiveness by analyzing whether the received bio signal exists within an effective segment.

8 . The multi-modal type wearable user authentication apparatus of claim 7 , wherein the control module extracts a first characteristic point related to a dynamic element from the received bio signal and extracts a second characteristic point related to a static element from the acquired fingerprint, if the effectiveness is effective.

9 . A multi-modal type wearable user authentication method performed by a multi-modal type wearable user authentication apparatus, the multi-modal type wearable user authentication method comprising:
acquiring a fingerprint through a bio recognition module; acquiring a bio signal through an electrode plate and first and second electrodes; detecting a finger pressure through a switch; receiving, when the finger pressure is detected, the acquired fingerprint and the acquired bio signal; and performing user authentication by analyzing a correlation between the received fingerprint and the received bio signal.

10 . A computer readable recording medium that can be executed by a computer that records a computer program of a multi-modal type wearable user authentication method comprising:
a function of acquiring a fingerprint through a bio recognition module; a function of acquiring a bio signal through an electrode plate and first and second electrodes; a function of detecting a finger pressure through a switch; a function of receiving the acquired fingerprint and the acquired bio signal, when the finger pressure is detected; and a function of performing user authentication by analyzing a correlation between the received fingerprint and the received bio signal.
