Abstract

An apparatus and method having biometric identification intrusion and access control. The apparatus features a monitoring system, visual input device and an audible input device. The visual and audible input devices are coupled to control circuits of the monitoring system which can implement an authentication process responsive to both visual and audile inputs.

Claims

1. An apparatus comprising:

a monitoring system which includes control circuits;

a visual input device coupled to the control circuits; and

an audible input device coupled to the control circuits wherein the control circuits, responsive to both visual and audile inputs, implement an authentication process.

2. An apparatus as in claim 1 wherein electrical signals from the visual input device are combined with signals from the audible input device to provide a multi-faceted authentication indicator.

3. An apparatus as in claim 2 wherein the control circuits determine actionable commands based on comparisons of the indicator to a set of decision rules.

4. An apparatus as in claim 3 which includes a manually operable input member to arm or disarm the monitoring system.

5. An apparatus as in claim 4 which includes additional circuits coupled to the control circuits to evaluate at least one of audible or visual instructions to arm or disarm the monitoring system.

6. An apparatus as in claim 2 wherein the control circuits combine the electrical signals to enroll authorized subjects and to generate a template of their respective facial features and voice elements.

7. An apparatus as in claim 6 wherein the control circuits progressively update the template of enrolled authorized subjects to account for physical changes and background changes.

8. An apparatus as in claim 6 wherein the control circuits capture at least one visual image of a subject'"'"'s facial features and a voice command from that subject.

9. An apparatus as in claim 8 wherein the control circuits recognize elements of the facial features and the voice command of the subject.

10. An apparatus as in claim 9 wherein the control circuits establish scores for the elements of the facial features and the voice command.

11. A process of authenticating a subject comprising:

initiating operation of a user authenticating process in response to one of recognizing a predetermined type of image, or, receiving an audio trigger;

providing substantially constant illumination at a face viewing region;

obtaining a sequence of images of a subject from the face viewing region;

using the sequence to detect face shapes;

obtaining audible input from the subject;

processing the audible input to identify a speaker identity; and

combining information from detected face shapes with the speaker identity and automatically determining an associated confidence score.

12. A process as in claim 11 wherein combining information is based on a rule set as functions of the face and voice score trustworthiness.

13. A process as in claim 11 which includes comparing the confidence score to a predetermined set of rules.

14. A process as in claim 13 where, responsive to results of the comparing, determining if one of access should be provided, further credentials from the subject should be requested, or an alarm should be initiated.

15. A process as in claim 14 which includes permitting the subject to disarm an alarm system.

16. A process as in claim 15 where disarming includes providing a visual or audible input and generating a disarm command.

17. A process as in claim 16 which includes providing a manually operable input for generating the disarm command.

18. A method of using biometric identification for disarming an alarm system comprising:

providing a detector/sensor unit having a camera for capturing images and text-dependent voice recognition;

enrolling authorized subjects and generating a template of their facial features and voice elements;

progressively enhancing the template to account for physical changes of the authorized subjects and background changes;

capturing at least one visual image of an individual'"'"'s facial features and a voice command from the individual;

recognizing elements of the facial features and the voice command of the individual;

establishing scores and trustfulness for the elements of the facial features and the voice command;

normalizing the face and voice scores based on minimum and maximum scores;

characterizing qualities of the face and voice elements based on the face and voice scores;

selecting a fusion weight from a quality and trustfulness matrix and computing a fused score;

comparing fused score against the template of enrolled authorized subjects;

disarming the alarm system where a template match is detected and denying access where a template match is not detected.
