Abstract

User interaction with a secure resource is controlled or mediated by the security server that includes a telephony interface by which the server is either coupled to the telephone system or provides messages to the telephone system directly or through an intermediate component. A biometric data store stores biometric data, such as speech data or visual recognition data. If desired the biometric data may also be stored in association with the extension identifiers of the telephone system. A biometric verification/.identification system accesses this data store and evaluates provided user biometric data vis-à-vis the stored biometric data to determine if the user may control or interact with the secure resource. If interaction is permitted, the security server sends control signals to the secure resource. The telephone system provides an interface through which the user trains the system to store the biometric verification/.identification data of that user.

Claims

1. An apparatus for interacting with a secure resource accessible through a telephone system of the type that provides telephone access through a plurality of extensions, comprising:

a security server having an interface for sending messages to said telephone system, said messages being adapted to provide control signals to said secure resource;

a biometric data store that stores biometric data associated with at least one user;

a biometric data input system coupled to said security server and operable to obtain user biometric data from said user;

said biometric verification/identification system being configured to access said data store and to evaluate said user biometric data vis-à

-vis said stored biometric data and to provide instructions to said security server and thereby provide control signals for interacting with said secure resource.

2. The apparatus of claim 1 wherein said interface is a telephony interface coupled to said telephone system.

3. The apparatus of claim 1 wherein said interface is an interface coupling said security server with an intermediate system that in turn communicates with said telephone system.

4. The apparatus of claim 1 wherein said interface is a network interface for communicating messages over a network between said security server and said telephone system.

5. The apparatus of claim 1 wherein said data store is configured to store biometric data in association with at least one of said plurality of extensions.

6. The apparatus of claim 1 wherein said biometric data input system is operable to obtain user biometric data from a user operating one of said plurality of extensions.

7. The apparatus of claim 1 wherein said security system is configurable through training to operate upon biometric data from said user.

8. The apparatus of claim 1 wherein said security system is configurable through training to operate upon biometric data from said user using training speech provided using said telephone system.

9. The apparatus of claim 1 wherein said security system includes direct interface for coupling to said secure resource.

10. The apparatus of claim 9 wherein said direct interface is a wired connection to said secure resource.

11. The apparatus of claim 9 wherein said direct interface is a network connection communicating with said secure resource.

12. The apparatus of claim 9 wherein said direct interface is a wireless connection communicating with said secure resource.

13. The apparatus of claim 1 wherein said biometric data input system is a voice input system.

14. The apparatus of claim 1 wherein said biometric data input system is a voice input system communicating with said telephone system through at least one of said extensions.

15. The apparatus of claim 1 wherein said biometric verification/identification system employs a speaker verification/identification system.

16. The apparatus of claim 1 wherein said biometric verification/identification system automatically determines an extension identifier associated with said one of said plurality of extensions being operated by said user, and uses said extension identifier in accessing said stored biometric data.

17. The apparatus of claim 1 wherein said biometric verification/identification system employs a speech recognition system that compares the user'"'"'s speech with a predefined list of keywords.

18. The apparatus of claim 1 wherein said biometric verification/identification system employs a speech recognition system that employs a wordspotting system for identifying keywords within a speech utterance.

19. The apparatus of claim 1 wherein said biometric verification/identification system employs a speaker verification/identification system that assesses at least one a text independent component and at least one text dependent component.

20. The apparatus of claim 1 wherein said security server couples to said telephone system as one of said plurality of extensions

21. A method of interacting with a secure resource accessible through a telephone system of the type that provides telephone access through a plurality of extensions comprising the steps of:

receiving user biometric data from a user operating one of said extensions;

obtaining user extension information that identifies which one of said extensions the user is operating;

using said user extension information and said user biometric data to access a data store containing stored biometric data associated with stored extension information;

evaluating said user biometric data vis-à

-vis said stored biometric data and providing instructions to interact with said secure resource based on the results of said evaluating step.

22. The method of claim 21 wherein said biometric data is speech data.

23. The method of claim 21 wherein said biometric data is speech data provided through said one of said extensions.

24. The method of claim 21 wherein said biometric data is speech data and said evaluating step is performed using a speaker verification/identification technique applied to said speech data.

25. The method of claim 21 wherein said biometric data is speech data and said evaluating step is performed using a speaker recognition to compare said speech data with a predefined set of keywords.

26. The method of claim 21 wherein said biometric data is stream of continuous speech data and said evaluating step is performed by wordspotting to identify keywords within said continuous speech data.

27. The method of claim 21 wherein said biometric data is stream of continuous speech data and said evaluating step is performed by assessing at least one text independent component and at least one text dependent component.

28. A method of interacting with a secure resource accessible through a telephone system of the type that provides telephone access through a plurality of extensions comprising the steps of:

receiving user biometric data from a user;

using said user biometric data to access a data store containing stored biometric data associated with said user;

evaluating said user biometric data vis-à

-vis said stored biometric data and providing instructions to interact with said secure resource based on the results of said evaluating step.

29. The method of claim 28 further comprising storing biometric data associated with a plurality of users.
