Abstract

A system and method is provided that authenticates a user using hybrid biometrics information, such as a user'"'"'s image information, a user'"'"'s voice information, etc. The user authentication method includes: acquiring a number of biometrics information; generating a number of authentication information corresponding to the acquired biometrics information; and performing an integral user authentication based on the by generated authentication information.

Claims

1. A user authentication method comprising:

receiving image information and voice information;

detecting a facial feature value and an object feature value based on the image information, and a voice feature value based on the voice information; and

performing an integral user authentication for authentication by determining whether the detected feature values match prestored information over a predetermined amount.

2. The method of claim 1, wherein performing the integral user authentication comprises at least one of the following:

determining whether a value for a preset word matches the detected voice feature value;

determining whether a motion state of an object of the image information is synchronized with the detected voice information; and

3. The method of claim 1, wherein performing the integral user authentication comprises:

displaying, by a controller, a randomly selected word; and

determining whether the detected voice feature value matches a feature value of the selected word over the predetermined amount.

4. The method of claim 1, further comprising:

generating facial authentication information for the facial feature value, motion information for the object feature value, and voice authentication information for the voice feature value to perform the integral user authentication.

5. The method of claim 4, further comprising:

determining that the authentication has failed when at least one of the facial authentication information, the voice authentication information, and the motion information is not authenticated.

6. A user authentication method comprising:

acquiring a number of biometrics information for authentication;

generating a plurality of authentication information corresponding to the acquired biometrics information respectively; and

performing an integral user authentication for authentication based on the generated authentication information by determining whether the detected feature values match previously stored information over a predetermined amount.

7. The method of claim 6, wherein the acquisition step comprises:

acquiring image information via a camera module; and

acquiring voice information via a microphone.

8. The method of claim 7, wherein the generation step comprises:

detecting a facial feature value and an object feature value based on the image information, and a voice feature value based on the voice information;

generating facial authentication information using the facial feature value;

generating voice authentication information using the voice feature value; and

generating motion information using the object feature value.

9. The method of claim 8, wherein the motion information comprises:

information regarding a motion state of a preset object.

10. The method of claim 8, wherein performing the integral user authentication comprises:

determining whether the authentication is successful based on the facial authentication information, the voice authentication information, and the motion information by determining whether the detected feature values match prestored information over a predetermined amount.

11. The method of claim 10, further comprising:

determining that the authentication has failed when at least one of the facial authentication information, the voice authentication information, and the motion information is not authenticated.

12. The method of claim 7, wherein the generation step comprises:

detecting a facial feature value and an object feature value based on the image information, and a voice feature value based on the voice information;

generating facial authentication information using the facial feature value;

generating voice authentication information using the voice feature value; and

generating synchronization information using the object feature value and the voice feature value.

13. The method of claim 12, wherein the synchronization information comprises:

information indicating whether the object feature value is synchronized with the voice feature value.

14. The method of claim 12, wherein performing the integral user authentication comprises:

determining whether the authentication is successful based on the facial authentication information, the voice authentication information, and the synchronization information by determining whether the detected feature values match prestored information over a predetermined amount.

15. The method of claim 14, further comprising:

determining whether the authentication has failed when at least one of the facial authentication information, the voice authentication information, and the synchronization information is not authenticated.

16. A mobile device comprising:

a camera module for acquiring an image;

a microphone for acquiring a voice; and

a controller for;

acquiring a facial feature value and an object feature value based on the acquired image information, and a voice feature value based on the acquired voice information; and

performing an integral user authentication for authentication by determining whether the detected feature values match prestored information over a predetermined amount.

17. The mobile device of claim 16, wherein the controller performs at least one of the following:
