Abstract

A telephonic authentication system, method and program product. An authentication system is provided for authenticating a user of a telephonic device that includes a setup system for capturing and storing an authentic user speech pattern sample; a comparison system that compares the authentic user speech pattern sample with an inputted speech pattern sample and generates a comparison result; and a control system for controlling access to the telephonic device. The control system analyzes the comparison result for an initial inputted speech pattern sample received when a telephone call is initiated and periodically analyzes comparison results for ongoing inputted speech pattern samples received during the telephone call.

Claims

1. An authentication system for authenticating a user of a telephonic device, comprising:

a setup system for capturing and storing an authentic user speech pattern sample;

a comparison system that compares the authentic user speech pattern sample with an inputted speech pattern sample and generates a comparison result; and

a control system for controlling access to the telephonic device, wherein the control system;

analyzes the comparison result for an initial inputted speech pattern sample received when a telephone call is initiated; and

periodically analyzes comparison results for ongoing inputted speech pattern samples received during the telephone call.

2. The authentication system of claim 1, wherein the control system terminates the telephone call if the authentic user speech pattern sample does not match the initial inputted speech pattern sample.

3. The authentication system of claim 2, wherein the control system terminates the telephone call if the authentic user speech pattern sample does not match an ongoing inputted speech pattern sample.

4. The authentication system of claim 1, wherein:

the setup system is configured for capturing and storing an authentic user voice sample;

the comparison system is configured for comparing the authentic user voice sample with an inputted voice sample and generating a comparison result; and

the control system;

analyzes the comparison result for an initial inputted voice sample received when a telephone call is initiated; and

periodically analyzes comparison results for ongoing inputted voice samples received during the telephone call.

5. The authentication system of claim 4, wherein the telephonic device comprises a system that provides access to a conference call.

6. The authentication system of claim 1, wherein the telephonic device includes an interactive collaboration system that shares data amongst a plurality of devices participating in a call in response to a recognized speech pattern.

7. The authentication system of claim 6, wherein the interactive collaboration system shares data selected from the group consisting of:

speaker information, attachments, and chat.

8. A method for authenticating a plurality of users accessing a conference call, comprising:

capturing and storing an authentic speech pattern sample for each user;

initiating access of a joining user to the conference call;

comparing an initial inputted speech pattern sample of the joining user with the authentic speech pattern samples and generating a compare result;

deciding whether to allow access to the conference call based on the compare result for the joining user;

periodically comparing ongoing inputted speech pattern samples for all joined users obtained during the conference call with the authentic speech pattern samples to generate a set of periodic compare results; and

deciding whether to terminate access to the conference call for any of the joined users based on the periodic compare results.

9. The method of claim 8, wherein deciding whether to allow access to the conference call based on the compare result for the initial inputted speech pattern sample includes:

denying access to the conference call if the initial inputted speech pattern sample does not match one of the authentic speech pattern samples.

10. The method of claim 9, wherein deciding whether to terminate access to the conference call based on the periodic compare for any joined users includes:

terminating the conference call for a joined user if one of the ongoing inputted speech pattern samples of the joined user does not match one of the authentic speech pattern samples.

11. The method of claim 8, further comprising:

capturing and storing an authentic voice sample for each user;

comparing an initial inputted voice sample of the joining user with the authentic voice samples and generating a second compare result;

deciding whether to allow access to the conference call based on the second compare result for the joining user;

periodically comparing ongoing inputted voice samples for all joined users obtained during the conference call with the authentic voice samples to generate a second set of periodic compare results; and

deciding whether to terminate access to the conference call for any of the joined users based on the second set of periodic compare results.

12. The method of claim 11, wherein deciding whether to terminate access to the conference call for any of the joined users is based on weighted average of the first and second sets of periodic compare results.

13. A program product stored on a computer readable medium, which when executed, authenticates a user of a device, comprising:

program code configured for capturing and storing an authentic user speech pattern sample and voice sample;

program code configured for comparing the authentic user speech pattern sample and voice sample with an inputted speech pattern sample and inputted voice sample respectively, and for generating a comparison result; and

program code configured for controlling access to the device by analyzing the comparison result for an initial inputted speech pattern sample and voice sample, and by periodically analyzing comparison results for ongoing inputted speech pattern samples and voice samples.

14. The program product of claim 13, further comprising program code configured for providing a collaborative interface through which information can be shared amongst a plurality of devices in response to inputted speech pattern samples and inputted voice samples.

15. The program product of claim 14, wherein the information shared amongst the plurality of devices is selected from the group consisting of:

speaker information, attachments, and chat.

16. The program product of claim 13, wherein the inputted speech pattern sample comprises a distinctive manner of oral expression, having a characteristic selected from the group consisting of:

phonetic duration, the duration between pauses, pitch, pause proportion, articulation rate, fluent speech rate, mean sentence length, and stuttering.

17. The program product of claim 16, wherein the inputted voice sample comprises a measure of frequency and amplitude.

18. The program product of claim 13, wherein the device comprises a telephone and access is terminated if the authentic user speech pattern sample does not match the initial inputted speech pattern sample.

19. The program product of claim 18, wherein the device terminates a telephone call if the authentic user speech pattern sample does not match an ongoing inputted speech pattern sample.

20. The program product of claim 13, wherein authentication of a user is based on a weighted average of a first compare result for a set of speech pattern samples and a second set of compare results for voice samples.

21. A method for deploying an authentication system for authenticating a user of a telephonic device, comprising:

providing a computer infrastructure being operable to;

capture and store an authentic user speech pattern sample;

compare the authentic user speech pattern sample with an inputted speech pattern sample and generate a comparison result; and

control access to the telephonic device, including;

analyzing the comparison result for an initial inputted speech pattern sample received when a telephone call is initiated; and

periodically analyzing comparison results for ongoing inputted speech pattern samples received during the telephone call.
