Abstract

An individual'"'"'s identity is verifiable using voice biometrics. A voice biometric system includes a receiver configured to receive, from a remote communications device, a voice biometric sample of a party attempting to obtain a service from a remote system. The service is provided contingent on authentication of the party as the individual. The voice biometric system also includes a processor configured to compare the voice biometric sample received by the receiver to voice biometric information obtained from a storage to authenticate the identity of the party as the individual. The receiver and processor are provided within a communications network.

Claims

1. A voice biometric system for verifying an individual'"'"'s identity, comprising:

a receiver, within a communications network, configured to receive, from a remote communications device remote from and intermediate to the voice biometric system and a remote system, a voice biometric sample, from a party attempting to obtain a service from the remote system via the remote communications device, the service being provided contingent on authentication of the party as the individual; and

a processor, within the communications network, configured to compare the voice biometric sample received by the receiver to voice biometric information obtained from a storage to authenticate the party as the individual,

wherein the authentication of the party as the individual is performed by the voice biometric system responsive to a selective request from the remote communications device.

2. The voice biometric system of claim 1,

wherein the voice biometric sample is packetized according to an internet protocol.

3. The voice biometric system of claim 1,

wherein the remote system further includes a remote client communications device configured to provide access to the service to a plurality of parties authenticated as individuals.

4. The voice biometric system of claim 1,

wherein the remote system further includes a transaction apparatus configured for use by the party to request the service.

5. The voice biometric system of claim 1,

wherein the remote communications device comprises a telephony device.

6. The voice biometric system of claim 1,

wherein the remote communications device comprises an intelligent peripheral communications platform in the communications network.

7. The voice biometric system of claim 1,

wherein the remote communications device comprises a voicemail communications platform in the communications network.

8. The voice biometric system of claim 1,

wherein the remote communications device comprises a wireless network communications platform in the communications network.

9. The voice biometric system of claim 1,

wherein the remote system is configured to selectively determine whether to request the authentication by the voice biometric system.

10. A method for verifying an individual'"'"'s identity, comprising:

receiving, within a voice biometric system in a communications network, from a remote communications device remote from and intermediate to the voice biometric system and a remote system, a voice biometric sample, from a party attempting to obtain a service from the remote system via the remote communications device, the service being provided contingent on authentication of the party as the individual; and

comparing, within the voice biometric system, the received voice biometric sample to voice biometric information obtained from a storage to authenticate of the party as the individual,

wherein the authentication of the party as the individual is performed by the voice biometric system responsive to a selective request from the remote communications device.

11. The method for verifying an individual'"'"'s identity of claim 10,

wherein the voice biometric system comprises a server.

12. The method for verifying an individual'"'"'s identity of claim 10,

wherein the voice biometric sample is packetized according to a voice over Internet protocol.

13. The method for verifying an individual'"'"'s identity of claim 10,

wherein the voice biometric system includes the storage from which the voice biometric information is obtained, and

wherein the storage comprises a speech characteristics database that stores pre-registered voice information in association with identification information that identifies the individual.

14. The method for verifying an individual'"'"'s identity of claim 10,

wherein the voice biometric system performs a confidence check to determine a probability that the party is the individual, and

wherein the party is authenticated as the individual based on the determined probability.

15. The method for verifying an individual'"'"'s identity of claim 10,

wherein authentication using the voice biometric system is provided as a subscription service.

16. A computer readable medium storing a program that verifies an individual'"'"'s identity, comprising:

a receiving code segment that receives, within a voice biometric system in a communications network, from a remote communications device remote from and intermediate to the voice biometric system and a remote system, a voice biometric sample from a party attempting to obtain a service from the remote system via the remote communications device, the service being provided contingent on authentication of the party as the individual; and

a comparing code segment that compares, within the voice biometric system, the received voice biometric sample to voice biometric information obtained from a storage to authenticate the party as the individual,

wherein the authentication of the party as the individual is performed by the voice biometric system responsive to a selective request from the remote communications device.

17. The computer readable medium of claim 16,

wherein voice biometric samples are received from a plurality of parties attempting to obtain a service from a plurality of remote systems.

18. The computer readable medium of claim 16,

wherein the remote communications device comprises a remote network communications platform, and

wherein voice biometric samples are received from a plurality of remote network communications platforms.

19. The computer readable medium of claim 16,

wherein the voice biometric information is received over the internet.

20. The computer readable medium of claim 16,

wherein the remote system further includes a transaction platform used by the public to conduct a financial transaction.
